You can get into this environment with: + +``` +$ ./pw-uninstalled.sh -b builddir +``` + +In most cases you would want to run the default pipewire daemon. Look +below for how to make this daemon start automatically using systemd. +If you want to run pipewire from the build directory, you can do this +by doing: + +``` +cd builddir/ +make run +``` + +This will use the default config file to configure and start the daemon. +The default config will also start `pipewire-media-session`, a default +example media session and `pipewire-pulse`, a PulseAudio compatible server. + +You can also enable more debugging with the `PIPEWIRE_DEBUG` and +`WIREPLUMBER_DEBUG` environment variables like so: + +``` +cd builddir/ +PIPEWIRE_DEBUG="D" WIREPLUMBER_DEBUG="D" make run +``` + +You might have to stop the pipewire service/socket that might have been +started already, with: + +``` +systemctl --user stop pipewire.service \ + pipewire.socket \ + pipewire-media-session.service \ + pipewire-pulse.service \ + pipewire-pulse.socket +``` + +## Installing + +PipeWire comes with quite a bit of libraries and tools, run: + +``` +meson install -C builddir +``` + +to install everything onto the system into the specified prefix. +Depending on the configured installation prefix, the above command +may need to be run with elevated privileges (e.g. with `sudo`). +Some additional steps will have to be performed to integrate +with the distribution as shown below. + +### PipeWire daemon + +A correctly installed PipeWire system should have a pipewire +process, a pipewire-media-session (or alternative) and an (optional) +pipewire-pulse process running. PipeWire is usually started as a +systemd unit using socket activation or as a service. + +Configuration of the PipeWire daemon can be found in +`/usr/share/pipewire/pipewire.conf`. Please refer to the comments in the +config file for more information about the configuration options. + +The daemon is started with: +``` +systemctl --user start pipewire.service pipewire.socket +``` + +If you did not start the media-session in pipewire.conf, you will +also need to start it like this: +``` +systemctl --user start pipewire-media-session.service +``` +To make it start on system startup: +``` +systemctl --user enable pipewire-media-session.service +``` +you can write ```enable --now``` to start service immediately. + +### ALSA plugin + +The ALSA plugin is usually installed in: + +On Fedora: +``` +/usr/lib64/alsa-lib/libasound_module_pcm_pipewire.so +``` +On Ubuntu: +``` +/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_pipewire.so +``` + +There is also a config file installed in: + +``` +/usr/share/alsa/alsa.conf.d/50-pipewire.conf +``` + +The plugin will be picked up by alsa when the following files +are in `/etc/alsa/conf.d/`: + +``` +/etc/alsa/conf.d/50-pipewire.conf -> /usr/share/alsa/alsa.conf.d/50-pipewire.conf +/etc/alsa/conf.d/99-pipewire-default.conf +``` + +With this setup, `aplay -l` should list a pipewire device that can be used as +a regular alsa device for playback and record. + +### JACK emulation + +PipeWire reimplements the 3 libraries that JACK applications use to make +them run on top of PipeWire. + +These libraries are found here: + +``` +/usr/lib64/pipewire-0.3/jack/libjacknet.so -> libjacknet.so.0 +/usr/lib64/pipewire-0.3/jack/libjacknet.so.0 -> libjacknet.so.0.304.0 +/usr/lib64/pipewire-0.3/jack/libjacknet.so.0.304.0 +/usr/lib64/pipewire-0.3/jack/libjackserver.so -> libjackserver.so.0 +/usr/lib64/pipewire-0.3/jack/libjackserver.so.0 -> libjackserver.so.0.304.0 +/usr/lib64/pipewire-0.3/jack/libjackserver.so.0.304.0 +/usr/lib64/pipewire-0.3/jack/libjack.so -> libjack.so.0 +/usr/lib64/pipewire-0.3/jack/libjack.so.0 -> libjack.so.0.304.0 +/usr/lib64/pipewire-0.3/jack/libjack.so.0.304.0 + +``` + +The provided `pw-jack` script uses `LD_LIBRARY_PATH` to set the library +search path to these replacement libraries. This allows you to run +jack apps on both the real JACK server or on PipeWire with the script. + +It is also possible to completely replace the JACK libraries by adding +a file `pipewire-jack-x86_64.conf` to `/etc/ld.so.conf.d/` with +contents like: + +``` +/usr/lib64/pipewire-0.3/jack/ +``` + +Note that when JACK is replaced by PipeWire, the SPA JACK plugin (installed +in `/usr/lib64/spa-0.2/jack/libspa-jack.so`) is not useful anymore and +distributions should make them conflict. + + +### PulseAudio replacement + +PipeWire reimplements the PulseAudio server protocol as a small service +that runs on top of PipeWire. + +The binary is normally placed here: + +``` +/usr/bin/pipewire-pulse +``` + +The server can be started with provided systemd activation files or +from PipeWire itself. (See `/usr/share/pipewire/pipewire.conf`) + +``` +systemctl --user start pipewire-pulse.service pipewire-pulse.socket +``` + +You can also start additional PulseAudio servers listening on other +sockets with the `-a` option. See `pipewire-pulse -h` for more info. + + +## Uninstalling + +To uninstall, run: + +``` +ninja -C builddir uninstall +``` + +Depending on the configured installation prefix, the above command +may need to be run with elevated privileges (e.g. with `sudo`). + +Note that at the time of writing uninstallation only works with the +same build directory that was used for installation.

Nodes can choose + (or be forced) to be scheduled asynchronously. The graph will not wait for + the output of the node to continue processing but it will use the output + of the previous cycle (or silence) instead. This adds one cycle of latency + but it can avoid having some nodes blocking the processing graph. Non realtime + streams and filters now also use this asynchronous processing instead of + their own slightly broken version. + * The concept of node.sync-group was added. This groups nodes with overlapping + sync-group together when one of them sets the node.sync = true. This is now + used to make sure all nodes are scheduled together when JACK transport is + started so that they all see the same transport time. + * Config parsing errors are reported earlier and much better with line and + column numbers where the parsing started to fail. + * Add support for mandatory metadata when negotiating buffer parameters. This + can be used to only negotiate extra buffer planes when certain metadata is + negotiated. One use case is the explicit sync support that requires 2 + extra fds for the timelines. + * Explicit sync metadata and support was added. + * Support was added for making and using multiple data-loops in the server + and clients. Support for CPU affinity and priorities was added to the + data-loops as well. + * The log topic debug levels can now be changed at runtime with metadata. + The log levels in the pulse server can be dynamically changed with a + /core message. + * The UCM conflicting devices patches were merged. + * Add snapcast-discover module to stream to snapcast servers. + * Rework how peers are linked and the counters are updated. Resume the + peers when a node is unlinked and not yet processed. This should cause + less occasional dropouts in the graph when reconnecting things. + * Many GStreamer element updates. + * Many more fixes and improvements. + +Enjoy the summer vacation! + + +## Highlights (since the previous 1.1.83 release) + - Small fixes here and there. + +## PipeWire + - Compilation fixes after enabling -Werror=float-conversion + +## Modules + - The module-rtp-sap now propagates the cleanup.sec property to the + rtp-source and the rtp-source now sets a property with the receiving + status. + - Fix for ROC 0.3, explicitly specify sender encoding.

Nodes can choose + (or be forced) to be scheduled asynchronously. The graph will not wait for + the output of the node to continue processing but it will use the output + of the previous cycle (or silence) instead. This adds one cycle of latency + but it can avoid having some nodes blocking the processing graph. Non realtime + streams and filters now also use this asynchronous processing instead of + their own slightly broken version. + - The concept of node.sync-group was added. This groups nodes with overlapping + sync-group together when one of them sets the node.sync = true. This is now + used to make sure all nodes are scheduled together when JACK transport is + started so that they all see the same time. + - Config parsing errors are reported earlier and much better with line and + column numbers where the parsing started to fail. + - Add support for mandatory metadata when negotiation buffer parameters. This + can be used to only negotiate extra buffer planes when certain metadata is + negotiated. One use case is the explicit sync support that requires 2 + extra fds for the timelines. + - Support was added for making and using multiple data-loops in the server + and clients. Support for CPU affinity and priorities was added to the + data-loops as well. + - The log topic debug levels can now be changed at runtime with metadata. + The log levels in the pulse server can be dynamically changed with a + /core message. + - The UCM conflicting devices patches were merged. + + +## PipeWire + - snap support has been added. + - Implement async processing. (#3509) + - Support for explicit sync was added. + - Config parsing errors are reported earlier and much better. + - A -P option was added to provide extra properties to the context. This can be + used to enable some features that use rules. + - properties.rules was added to enhance properties based on some rules. + This deprecates the vm.overrides. + - Support was added for security-context. This makes it possible for a flatpak + to request a socket with specific properties from pipewire to mount in the + flatpak. The session manager can then assign permissions based on the connection + properties. + - Support for fixed arrays in pw_array was improved. + - PipeWire server and clients can now use multiple threads to process the nodes + in parallel. + - device.rules and node.rules were added to update device and node properties + based on rules. + - device.param and node.param can now be used to configure params when devices + and nodes are created. + - Memory will now try to use MFD_NOEXEC_SEAL. + - The driver id of a node is now placed in the properties. + - A potential race was fixed when adding and removing ports to the scheduling + lists. + +## Modules + - Priorities for the FFADO threads can be configured now. + - The loopback module now has support for up and downmixing. + - Extra properties can now be configured per native-connection socket. + - The pulse-tunnel can now automatically reconnect when the connection is + broken. + - The RTP module now supports the PTP management protocol. + - The RTP sender can now use a timer to send out multiple packets per + quantum. + - A new module was added for loading Parametric EQ. + - The simple-protocol module now has per stream configurable properties + and can also be used to interface with a snapcast server. + - Support for local services was added to raop, rtp and pulse avahi + discoverers.

(#3149) + +# PipeWire 0.3.68 (2023-04-06) + +This is a bugfix release that is API and ABI compatible with previous +0.3.x releases. + +This release contains a huge number of changes, some of which might cause +regressions. Please report anything that seems to fail after the upgrade. +UCM devices in particular might have changed names, profiles and ports that +might require changes in custom scripts. + +## Highlights + - Symbolic links to the pipewire binary are now used instead of recompiling + the same binary multiple times. + - Changes to the graph scheduler related to quantum/rate updates and + calculation of the node states. Things should start and switch between + quantums and rates more smoothly now and especially virtual devices should + now only run when required. + - A new RTP session module was added. This uses the Apple MIDI protocol + to configure low-latency bidirectional MIDI (and with a PipeWire specific + extension, also audio) between machines. OPUS encoding was added to the + RTP formats. The SAP module was separated from the rtp-sink/source module + to make it more usable. + - A new runtime debug property was added to all streams and nodes to trigger + a save of the raw samples to a wav file. Support for this has also been + added to the echo-canceler to debug potential issues. + - Module pulse-tunnel has improved rate matching and synchronization + support. It should also not drift anymore for capture devices. + - The link-factory now ignores by default the link.passive property. This means + that tools like pw-link or jack clients and wireplumber can't make passive + links anymore. The reason is that there is now much more advanced logic in + PipeWire itself to handle passive links based on node and port properties. + - The RAOP sink was ported to new OpenSSL functions. Digest passwords are + handled correctly now and support for more devices was added. + - The ACP code was updated with new PulseAudio UCM code: "Create multiple + profiles per verb for conflicting devices". This might change the names + of devices, profiles and ports so scripts might need to be updated. + - Upmixing is disabled again by default. We now ship config files that + distros can install to enable upmixing again. The reason being that PipeWire + should not apply fancy DSP processing to audio by default. + - Many cleanups and bugfixes, including some crashes and memory corruption + bugs. + +## PipeWire + - Various FreeBSD compilation fixes. + - Don't crash when calling _connect twice in stream/filter. (#3091) + - Links are now installed instead of compiling the pipewire binary + multiple times. + - There is now a new core event bound_props that augments the bound_id event + with the global properties. This can be used to get the global.serial among + other global properties. It also makes it possible in the future to let the + server allocate unique names or uuids. + - Fix a bug where the server could go into an infinite reconfigure loop when + the samplerate of a driver would change. + - When a samplerate was forced, restore the previous best samplerate when the + samplerate is no longer forced. (#2133) + - Rework how the states of the nodes in the graph are calculated. A more + refined algorithm is now used that only runs nodes that need to run. + - Rework how the quantum change is applied to the graph. Drivers are now + responsible for using the new updated rate/quantum before starting a new + cycle. This avoids starting a cycle with an old quantum first. + - pw-stream and pw-filter will now ensure that the Trigger event is called + from the main thread. + - node.force-rate=0 will now force the node.rate on the graph, forcefully + switching the hardware into the new rate if possible. (#3026) + - Additional checks were added to the thread-loop to check locking order. + - Additional checks were added to pw-stream and pw-filter to check if methods + are called from the right thread context. + +## modules + - A new RTP session module was added. This uses the Apple MIDI protocol + to configure bidirectional MIDI (or audio) between machines. + - SAP support was removed from module-rtp-source and module-rtp-sink and + moved to a separate module. This makes it possible to use the RTP modules + without SAP support as well. + - The echo-cancel module now has support to save the signals to a wav + file for debugging purposes. + - The RTP modules now have support for the OPUS codec. + - The RAOP module was ported to new openssl encryption functions and handles + digest passwords correctly now. + - module-raop-discover now has match rules to be able to select the streams + and set properties. + - Module pulse-tunnel has improved rate matching and synchronization + support. (#3093) + - Fix potential memory corruption and infinite loops because + module-pulse-tunnel was unloaded from the wrong thread. + - The link-factory now ignores by default the link.passive property. This means + that tools like pw-link or jack clients and wireplumber can't make passive + links anymore. The reason is that there is now much more advanced logic in + PipeWire itself to handle passive links based on node and port properties. + - module-echo-cancel will now clear its buffers after a suspend to avoid + playing stray samples. + - module-raop-sink will now handle 0 timing_port replies. (#3133) + +## SPA + - The adapter module now has support for saving the raw audio to a wav + file for debugging purposes. + - The ACP code was updated with new PulseAudio UCM code: "Create multiple + profiles per verb for conflicting devices". This might change the names + of devices, profiles and ports so scripts might need to be updated. + - Upmixing was disabled again by default. We now ship config files that + distros can install to enable upmixing again. (#3081) + - audioadapter and audioconvert have seen improvements in the experimental + non-DSP/passthrough mode. + - Fix a potential race where the dummy drivers could fail to stop a timer + and cause endless warnings in the logs. + - The ALSA plugin has experimental support for IRQ based scheduling. This + should decrease latency for some (mostly USB) drivers. This should bring + latency within JACK latency. More work on this will be done before the + 1.0 release later this year. + - Audioconvert now has support for volume ramping. (#3046) + - A new loop method was added the check if a thread is currently running the + loop. + - channelmix.disable and resample.disable now generate an error when true + and channelmixing or resampling is required in the converter. + +## Bluetooth + - Fix a crash in some cases when a device was disconnected. + - Support async transport state changes. This avoids some lockups when the + bluetooth backend is having issues. (#3023) + - Align BAP sinks. This improves synchronization between earpieces. + +## ALSA + - Improve properties in pw-top and pavucontrol. + +## pulse-server + - Improve error handling from pulse-tunnel. + - Generate silence correctly for unsigned formats as well. + - Review buffer params. The streams should now just work with 1 or 2 + buffers. + - module-rtp-send and module-rtp-recv now have support for the OPUS codec. + +# JACK + - Make sure we don't call any callbacks anymore when deactivating. (#2781) + +## GStreamer + - Sort the device by priority in deviceprovider. (#3072) + +# PipeWire 0.3.67 (2023-03-09) + +This is a bugfix release that is API and ABI compatible with previous +0.3.x releases. + +## Highlights + - The loopback module and other couples streams will now not randomly + fail in some cases. (#3028) + - The RTP module now has support for sending and receiving MIDI as + well. + - The compress offload sink has seen many improvements. It now uses + ioctls directly to bypass limitations of tinycompress (to be able + to detect the available codecs, for example). + - Pulse server compatibility was improved for some apps by improving + the format parsing and FIX_ stream flag handling. + - The min quantum in the pulse server was changed from 256/48000 to + 128/48000 to fix some issues with games that expect 5ms or less of + latency. + - The Bluetooth plugin has seen many improvements in packet scheduling + to attempt to reduce stuttering on some devices. + - The ALSA plugin now handles some impossible cases better. This fixes + recording in QEMU again. (#2971) + +## PipeWire + - SPDX tags were added to the code for copyright information. + - The random number functions were made more usable. + - The port property code was moved from the adapter to the port + implementation itself to make it more useful and unified for the + cases where no adapter is used (midi and video). + - Fix a potential overflow in mixer areas. + - Improve runnable state calculations of nodes. This is part of + ongoing work to avoid running nodes that should not need to run. + - The stream will now always call the process function when using + trigger, even if there are no buffers. This avoids stalls of the + processing graph in some cases. (#3028) + - Links are now marked as passive by PipeWire itself so that + the right thing happens in all cases. + - Implement the in/out/true values for the node.passive property. + Place a passive state on ports to make passive links on a port + by port basis. + +## Tools + - pw-cat has seen improvements in the encoded file playback case. + +## Modules + - The rtp module has support for MIDI now. + - DSCP is now configurable in the RTP module. + - The loopback module doesn't randomly fail to work anymore. (#3028) + +## SPA + - The null-audio sink can now be given a format and it will return this + instead of the default float ones. This makes it possible to make a + null-sink that has a given format. + - The compress offload sink has seen many improvements. It now no longer + uses tinycompress to be able to detect the available codecs. + - The ALSA plugin now handles some impossible cases better. (#2971) + - Fix compilation on older compilers. (#3050) + +## Pulse-server + - The FIX_ flags are now implemented more correctly by fixating the + stream to the format of the sink/source they ask to be connected to. + There is now also an option to override the fixation based on rules. + - Format parsing was improved and should now support all format strings + supported by pulseaudio including upper and lower case variants + and shortcuts. + - Channelmap parsing was improved and should now reject invalid + channelmaps as well as support the shortcuts supported by pulseaudio. + - Escape codes in module arguments now work as it does in pulseaudio. (#3071) + - The min quantum was changed from 256/48000 to 128/48000 to fix some + issues with games that expect 5ms or less of latency. + +## JACK + - jack.passive-links can now be used to have a JACK client make passive + links and the node.passive property is no longer used for this because + it has a different function. + - The qsynth rule was updated to the new node.passive features. It is now + only passive on the output side. + +## Bluetooth + - BAP delay and transport latency are handled now. + - A2DP and SCO can now use bigger buffers to improve quality when the + reception is jittery. + - The AT+BCC command is now implemented. + - Packet encoding now happens ahead of time when possible to avoid delays + before sending it. + - Source should now always produce complete (padded) buffers to avoid sync + problems. + - Don't set unnecessary socket options. + +## GStreamer + - The pipewiresrc now has an autoconnect argument. + - The metadata plane count is now handled correctly in more cases. + - Stream errors are now handled correctly to stop the GStreamer elements. + +# PipeWire 0.3.66 (2023-02-16) + +This is a bugfix release that is API and ABI compatible with previous +0.3.x releases. + +## Highlights + - Fix a regression in the pulseaudio module-combine-stream because the new + module-combine-stream was not installed. + - PipeWire can now generate a limits.d config file with our recommended + settings for priorities and memlock. + - Modules, exec and objects can now be loaded depending on conditions. One + example is the X11-bell module that can now be disabled with a custom + property override. + - Filter-chain has a new mysofa based spacializer plugin. + - Support was added for different clocks that allow the RTP modules to work + with a PTP clock, for example. + - Many bugfixes and improvements. + + +## PipeWire + - Avoid rate switches when the graph is idle. + - The rate selection algorithm was improved. This ensures minimal performance + and quality loss when resampling. + - The default min.quantum was set to 32 again after it got erroneously changed + to (the too low) 16 in version 0.3.45. + - Fix compilation issues with rust bindings because of macros in defines. + Work around it for now. (#2952) + - Invalid file mappings are now refused (#2617 #2914 #3007) + - Modules, exec and objects can now be loaded depending on conditions. One + example is the X11-bell module that can now be disabled with a custom + property override. + - Filter now also supports _trigger_process() to drive the graph. + - TID is now added to the journald log. + - PipeWire generates and installs */etc/security/limits.d/25-pw-rlimits.conf* + that by default contains project's recommended settings. Creation of the + pipewire group is left to the distro or user ( `groupadd -r pipewire` ). + See the rlimits-* Meson options for controlling this behavior. + - Additionally there is now by default disabled Meson option that will + install */etc/security/limits.d/20-pw-defaults.conf* with the current Linux + default memlock value. Distros with only kernels >=5.16 or always using + systemd v251 or newer do not need this. But all other builds should set the + `-Dpam-defaults-install=true` Meson option to ensure that the memlock value + is always large enough. Thanks to Rickie Schroeder for pointing out that + the default Linux memlock value has been somewhat recently increased. + +## modules + - Install module-combine-stream. + - RTP source now has support for custom channel names. + - RTP source will now stop when inactive. + - Filter-chain has a new mysofa based spacializer plugin. + - The RTP modules can now use direct clock timestamps to send and receive + packets.

Higher + quality formats with higher performance are chosen first. + * Make sure the time reported by pw_stream is always increasing, + even when the driver and clock changes. + * There is now also a system service and socket that can be used + to enable PipeWire systemwide. This is however not recommended + and disabled by default. + * Fix channelmixer 5.1 to stereo mix matrix. It was not reading + the conversion matrix correctly and cause channels to be + dropped. The channelmixer will now also normalize the volume, + like what pulseaudio does. + * The channelmixer will now just copy channels when no layout + has been given. It has also optimized paths for this. This + makes it possible for apps to request > 8 channels from the + alsa plugin (ardour). + * Port, Node and Link will now also emit an error on the + resources in addition to updating the error in the info. This + would make it easier to track negotiation errors in the session + manager later. + * many small fixes and cleanups. + * Fix compatibility: + + DOSBox: fix crash because of double free in pw_stream + +- Session manager improvements + * The session manager will now try to configure the client to + the channel configuration of the sink/source.

This + catches some old apps linked against 0.2 that want to use the + alsa plugin. + * Fix compatibility: + + linphone (ALSA SIGFPE when _status() is called + before _prepare()). + +PipeWire 0.3.10 + +This is a bugfix release that is API and ABI compatible +with previous 0.3.x releases. + +- Many improvements to the pulse layer. + * GStreamer pulsesink element now works. + * Fixes some segfaults. + * Enable rtkit for client threads. + * fixes capture of monitor stream by name + * implement some more extensions, this makes paman + work and removes some warnings. + +- Many improvements to the GStreamer elements + * negotiation rework, avoid calling GStreamer methods from + the PipeWire callbacks because they might block and cause + deadlocks. + * Add support for non-string property values. + * improve stability after buffer and format + renegotiation. + * Rework the device provider. + * pipewiresink can now provide a stream that can + be consumed by apps like cheese. + +- Many improvements to the JACK layer: + * Rework the buffer_size callbacks. Make sure we call + the callback from a 'safe' thread and that we don't + call the process callback while the application is + handling the callback. This improves stability in + apps like Carla when PipeWire dynamically changes + the buffer size. + * Improve compatibility with apps that call + get_buffer_frames() with a 0 size (calfjackrack) + * JACK can now create nodes that can be set as a + sink/source in PulseAudio/ALSA apps (you can make an + effects rack and set that as default sink for + apps). + +- Added a group id property for nodes. This makes it + possible to schedule nodes with the same driver even + when they are otherwise not linked together. To make + this work well a new flag needed to be added to nodes + to signal when they are ready for processing. + + Together with the GStreamer fixes, this makes things + like: + + gst-launch-1.0 -v pipewiresrc path=51 stream-properties="props,node.group=1" ! + audio/x-raw ! pipewiresink stream-properties="props,node.group=1" + + work as expected with PipeWire managing the resampling + to keep the clocks of the devices in sync. + + This can later also be used to force devices to be grouped + together to create a JACK-like scheduling group. + +- Streams and filter now use PIPEWIRE_NODE and + PIPEWIRE_LATENCY env variables as fallback. + +- ACP add per device port list. This makes UCM devices + expose the right ports. + +- Fix some segfaults in ACP and UCM. + +- make pw-cat use the metadata to find default devices. + +- The media session can now save and load audio device + Profiles and Routes (volumes), stream volumes and + the default sink and sources. + +PipeWire 0.3.9 + +This is a bugfix release that is API and ABI compatible +with previous 0.3.x releases. + +- Fix bad audio in chrome + +- Remove some errors that are not real errors. + +- Fix 100% cpu when disconnecting devices. + +- Improve pulseaudio introspection of formats + +- Fix JACK metadata handling, carla can now monitor the + port it creates and insert midi. + +- Add a new permission bit (M) that is needed to be able + to configure metadata on an object.

This can be used to make + JACK nodes look like a device (like an effects rack). + +- Improvements in the session manager in how it links + ports. Now it will try to link matching channels first + and be more intelligent otherwise. The session manager + will also configure the stream to the device port + configuration when needed. + +- Add ofono backend for Bluetooth HeadSet support. + +- Improve default source and sink handling. They are now + stored with their id, instead of name, in the metadata. + This makes it work better with JACK because of JACK's + limited name length. + +- Improve environment variables to make it possible to + create and connect to servers other than "pipewire-0". + Implement this in pulseaudio, JACK and alsa layers. + +- Add an alsa mixer plugin so that alsamixer works with + PipeWire. It will configure the default source/sink + volumes. + +- Fix capture devices. There was something wrong with how + the resampler was used that caused corruption in the + signal when the resampler was active. + +- We now ship alsa card paths, profile-sets configuration + files and udev rules so that we don't have to rely on + the pulseaudio ones. + +- Many build and stability fixes. + + +PipeWire 0.3.7 + +This is a bugfix release that is API and ABI compatible +with previous 0.3.x releases. + +- Improved PulseAudio compatibility. The alsa card profile + code was reused from PulseAudio. Devices now support + all profiles, ports, jack detection, UCM and hardware + mixers that PulseAudio implements. There should not + be (almost) any difference between PipeWire and PulseAudio + in how it presents and manages devices. + Other missing API pieces such as the default sink/source + and move_stream are implemented now. At this point + it should be possible to replace PulseAudio with the + compatibility layer for those who want to try. + +- Many fixes and improvements to the GStreamer elements. + pipewiresrc now has the ability to periodically resend + the last frame. This makes it possible for use-cases like + screensharing to only update the screen on changes while + still keeping the client side encoder busy. PipeWire + elements can now also share a connection between them. + +- Improvements to the bluetooth nodes. Dynamically adding + and removing devices should work much smoother now. Many + fixes and improvements to a2dp and sco nodes. + +- Reduced memory usage by using less pre-allocated memory + where possible. JACK clients are especially using less + memory. + +- Support for passive links is added again. These are links + that don't cause the associated driver to become active. + This makes it possible to have blocks of effects+sinks go + to suspend as a group when not in use. + +- Both consumers and producers can now ask to renegotiate + the format. This required some cleanups and improvements + to how links and node states were handled. More work is + needed to implement more use cases. + +- Important fixes to how memory is shared with clients. Memory + was not correctly freed in all cases, which would result + in reuse of the wrong memory. + +- Support for planar formats for audio and video was added. + +- Improved error handling in the session manager. + +- Metadata is now used to manage default audio source and + sink devices. The session manager will try to link streams + to the default device. Changing the default device will + move streams to the new device. PulseAudio and JACK layers + respect the default source/sinks. + +- Metadata is used to tag the desired output device for + a stream and the session manager will move streams when + the metadata changes. The PulseAudio layer uses this to + implement the move_stream feature. + +- Many fixes to the security modules. The session manager now + has a flatpak module that grants permissions to flatpak + apps. The PulseAudio layer now respects the permissions of + objects. Security related properties are made read-only + now. Different access modules can now coexist. + +- The portal module has been split up in 2 parts: + 1) a part living in the daemon that monitors the portal + dbus owner and tags all clients from this PID. This + part has to run in the daemon in order to securely + tag the clients. + 2) a part in the session manager that uses the permission + store to manage the permissions of portal managed + clients. + + +PipeWire 0.3.6 + +This is a bugfix release that is API and ABI compatible +with previous 0.3.x releases. + +- Extensive memory leak fixing and stress testing was done. + A big leak in screen sharing with DMA-BUF was fixed. +- Compile fixes +- Stability improvements in jack and pulseaudio layers. +- Added the old portal module to make the Camera portal + work again.

Also properly pause inactive nodes. +- Use "true" and "false" in properties when we are talking + about a boolean. +- pulseaudio: improve compatibility + + +PipeWire 0.3.0 + +The 0.3 release is a major milestone in the development of +PipeWire. It features a complete redesign of the scheduling +mechanisms that make it possible to run a JACK compatibility +layer with comparable performance to JACK2. + +The API has been reworked and is declared stable now. All +development files and runtime paths are versioned so that +future incompatible changes can be done without breaking +existing applications. + +PipeWire 0.3 also includes a (now mandatory) session manager +that populates and controls the PipeWire graph. This example +session manager is very simple and not configurable. It is +expected that future version will either switch to a more +flexible session manager (like WirePlumber) or improve the +configuration options of the example session manager. + +PipeWire 0.3 includes both PulseAudio, JACK and ALSA +compatibility libraries that are known to support a wide range +of applications. The ALSA library is pretty complete at this +point. The JACK and mostly the PulseAudio compatibility +libraries need more work. See the Wiki pages for the current +compatibility problems. We do not yet encourage people to +switch away from their existing audio solutions (PulseAudio +or JACK) but we would love to hear from people who try it +anyways. Future versions will mostly focus on improving +compatibility further to make PipeWire a drop-in replacement. + +PipeWire comes with some GStreamer plugins to consume and +produce data for PipeWire. The consumer (pipewiresrc) is +working well in most cases. The sink (pipewiresink) is known +to be somewhat problematic for now. + +PipeWire 0.2.97 + +Eighth pre-release for upcoming 0.3: + +- Build fixes +- pw-cat improvement: Fix remote name, add midi support +- add device subscribe params for completeness +- jack and pulseaudio compatibility fixes +- Fix a bug in resampler, add quality option, tweaked quality + settings, tested now against https://src.infinitewave.ca/ + testsignals and submitted results for publication. +- Fix awkwardness in buffer negotiations, the default number of + buffers was 4 and jack could only handle 2, causing + corruption.

This includes: + + - Making available sources of video (such as from a capture devices or + application provided streams) and multiplexing this with + clients. + - Accessing sources of video for consumption. + - Generating graphs for audio and video processing. + +Nodes in the graph can be implemented as separate processes, +communicating with sockets and exchanging multimedia content using fd +passing. + +## Building and installation + +The preferred way to install PipeWire is to install it with your +distribution package system. This ensures PipeWire is integrated +into the rest of your system for the best experience. + +If you want to build and install PipeWire yourself, refer to +[install](INSTALL.md) for instructions. + +## Usage + +The most important purpose of PipeWire is to run your favorite apps. + +Some applications use the native PipeWire API, such as most compositors +(gnome-shell, wayland, ...) to implement screen sharing. These apps will +just work automatically. + +Most audio applications can use either ALSA, JACK or PulseAudio as a +backend. PipeWire provides support for all 3 backends. Depending on how +your distribution has configured things this should just work automatically +or with the provided scripts shown below. + +PipeWire can use environment variables to control the behaviour of +applications: + +* `PIPEWIRE_DEBUG=` to increase the debug level (or use one of + `XEWIDT` for none, error, warnings, info, + debug, or trace, respectively). +* `PIPEWIRE_LOG=` to redirect log to filename +* `PIPEWIRE_LOG_SYSTEMD=false` to disable logging to systemd journal +* `PIPEWIRE_LATENCY=` to configure latency as a fraction. 10/1000 + configures a 10ms latency. Usually this is + expressed as a fraction of the samplerate, + like 256/48000, which uses 256 samples at a + samplerate of 48KHz for a latency of 5.33ms. + This function does not attempt to configure + the samplerate. +* `PIPEWIRE_RATE=` to configure a rate for the graph. +* `PIPEWIRE_QUANTUM=` to configure latency as a fraction and a + samplerate. This function will force the graph samplerate to + `denom` and force the specified `num` as the buffer size. +* `PIPEWIRE_NODE=` to request a link to the specified node. The + id can be a node.name or object.serial of the target node. + +### Using tools + +`pw-cat` can be used to play and record audio and midi. Use `pw-cat -h` to get +some more help. There are some aliases like `pw-play` and `pw-record` to make +things easier: + +``` +$ pw-play /home/wim/data/01.\ Firepower.wav +``` + +### Running JACK applications + +Depending on how the system was configured, you can either run PipeWire and +JACK side-by-side or have PipeWire take over the functionality of JACK +completely. + +In dual mode, JACK apps will by default use the JACK server. To direct a JACK +app to PipeWire, you can use the `pw-jack` script like this: + +``` +$ pw-jack +``` + +If you replaced JACK with PipeWire completely, `pw-jack` does not have any +effect and can be omitted. + +JACK applications will automatically use the buffer-size chosen by the +server. You can force a maximum buffer size (latency) by setting the +`PIPEWIRE_LATENCY` environment variable like so: + +``` +PIPEWIRE_LATENCY=128/48000 jack_simple_client +``` +Requests the `jack_simple_client` to run with a buffer of 128 or +less samples. + + +### Running PulseAudio applications + +PipeWire can run a PulseAudio compatible replacement server. You can't +use both servers at the same time. Usually your package manager will +make the server conflict so that you can only install one or the +other. + +PulseAudio applications still use the regular PulseAudio client +libraries and you don't need to do anything else than change the +server implementation. + +A successful swap of the server can be verified by checking the +output of + +``` +pactl info +``` +It should include the string: +``` +... +Server Name: PulseAudio (on PipeWire 0.3.x) +... +``` + +You can use pavucontrol to change profiles and ports, change volumes +or redirect streams, just like with PulseAudio. + + +### Running ALSA applications + +If the PipeWire alsa module is installed, it can be seen with + +``` +$ aplay -L +``` + +ALSA applications can then use the `pipewire:` device to use PipeWire +as the audio system. + +### Running GStreamer applications + +PipeWire includes 2 GStreamer elements called `pipewiresrc` and +`pipewiresink`. They can be used in pipelines such as this: + +``` +$ gst-launch-1.0 pipewiresrc ! videoconvert ! autovideosink +``` + +Or to play a beeping sound: + +``` +$ gst-launch-1.0 audiotestsrc ! pipewiresink +``` + +PipeWire provides a device monitor as well so that + +``` +$ gst-device-monitor-1.0 +``` + +shows the PipeWire devices and applications like cheese will +automatically use the PipeWire video source when possible. + +### Inspecting the PipeWire state + +To inspect and manipulate the PipeWire graph via GUI, you can use [Helvum](https://gitlab.freedesktop.org/ryuukyu/helvum). + +Alternatively, you can use use one of the excellent JACK tools, such as `Carla`, +`catia`, `qjackctl`, ... +However, you will not be able to see all features like the video +ports. + +`pw-mon` dumps and monitors the state of the PipeWire daemon. + +`pw-dot` can dump a graph of the pipeline, check out the help for +how to do this. + +`pw-top` monitors the real-time status of the graph. This is handy to +find out what clients are running and how much DSP resources they +use. + +`pw-dump` dumps the state of the PipeWire daemon in JSON format. This +can be used to find out the properties and parameters of the objects +in the PipeWire daemon. + +There is a more complicated tool to inspect the state of the server +with `pw-cli`. This tool can be used interactively or it can execute +single commands like this to get the server information: + +``` +$ pw-cli info 0 +``` + +## Documentation + +Find tutorials and design documentation [here](doc/index.dox). + +The (incomplete) autogenerated API docs are [here](https://docs.pipewire.org). + +The Wiki can be found [here](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/home) + +## Contributing + +PipeWire is Free Software and is developed in the open.

In this example we use +`dlopen()` as the method used on Linux. + +A plugin always consists of two parts, the vendor path and then the .so file. + +As an example we will load the "support/libspa-support.so" plugin. You will +usually use some mapping between functionality and plugin path as we'll see +later, instead of hardcoding the plugin name. + +To `dlopen` a plugin we then need to prefix the plugin path like this: + +\code{.c} +#define SPA_PLUGIN_DIR /usr/lib64/spa-0.2/" +void *hnd = dlopen(SPA_PLUGIN_DIR"/support/libspa-support.so", RTLD_NOW); +\endcode + +The environment variable `SPA_PLUGIN_DIR` and `pkg-config` variable +`plugindir` are usually used to find the location of the plugins. You will +have to do some more work to construct the shared object path. + +The plugin must have exactly one public symbol, called +`spa_handle_factory_enum`, which is defined with the macro +`SPA_HANDLE_FACTORY_ENUM_FUNC_NAME` to get some compile time checks and avoid +typos in the symbol name. We can get the symbol like so: + +\code{.c} +spa_handle_factory_enum_func_t enum_func; +enum_func = dlsym(hnd, SPA_HANDLE_FACTORY_ENUM_FUNC_NAME)); +\endcode + +If this symbol is not available, the library is not a valid SPA plugin. + + +# Enumerating Factories + +With the `enum_func` we can now enumerate all the factories in the plugin: + +\code{.c} +uint32_t i; +const struct spa_handle_factory *factory = NULL; +for (i = 0;;) { + if (enum_func(&factory, &i) <= 0) + break; + // check name and version, introspect interfaces, + // do something with the factory. +} +\endcode + +A factory has a version, a name, some properties and a couple of functions +that we can check and use. The main use of a factory is to create an +actual new object from it. + +We can enumerate the interfaces that we will find on this new object with +the `spa_handle_factory_enum_interface_info()` method. Interface types +are simple strings that uniquely define the interface (see also the type +system). + +The name of the factory is a well-known name that describes the functionality +of the objects created from the factory. `` contains +definitions for common functionality, for example: + +\code{.c} +#define SPA_NAME_SUPPORT_CPU "support.cpu" // A CPU interface +#define SPA_NAME_SUPPORT_LOG "support.log" // A Log interface +#define SPA_NAME_SUPPORT_DBUS "support.dbus" // A DBUS interface +\endcode + +Usually the name will be mapped to a specific plugin. This way an +alternative compatible implementation can be made in a different library. + + +# Making A Handle + +Once we have a suitable factory, we need to allocate memory for the object +it can create. SPA usually does not allocate memory itself but relies on +the application and the stack for storage. + +First get the size of the required memory: + +\code{.c} +struct spa_dict *extra_params = NULL; +size_t size = spa_handle_factory_get_size(factory, extra_params); +\endcode + +Sometimes the memory can depend on the extra parameters given in +`_get_size()`. Next we need to allocate the memory and initialize the object +in it: + +\code{.c} +handle = calloc(1, size); +spa_handle_factory_init(factory, handle, + NULL, // info + NULL, // support + 0 // n_support + ); +\endcode + +The info parameter should contain the same extra properties given in +`spa_handle_factory_get_size()`. + +The support parameter is an array of `struct spa_support` items. They +contain a string type and a pointer to extra support objects. This can +be a logging API or a main loop API for example. Some plugins require +certain support libraries to function. + + +# Retrieving An Interface + +When a SPA handle is made, you can retrieve any of the interfaces that +it provides: + +\code{.c} +void *iface; +spa_handle_get_interface(handle, SPA_NAME_SUPPORT_LOG, &iface); +\endcode + +If this method succeeds, you can cast the `iface` variable to +`struct spa_log *` and start using the log interface methods. + +\code{.c} +struct spa_log *log = iface; +spa_log_warn(log, "Hello World!\n"); +\endcode + + +# Clearing An Object + +After you are done with a handle you can clear it with +`spa_handle_clear()` and you can unload the library with `dlclose()`. + + +# SPA Interfaces + +We briefly talked about retrieving an interface from a plugin in the +previous section. Now we will explore what an interface actually is +and how to use it. + +When you retrieve an interface from a handle, you get a reference to +a small structure that contains the type (string) of the interface, +a version and a structure with a set of methods (and data) that are +the implementation of the interface. Calling a method on the interface +will just call the appropriate method in the implementation. + +Interfaces are defined in a header file (for example see +`` for the logger API). It is a self contained +definition that you can just use in your application after you `dlopen()` +the plugin. + +Some interfaces also provide extra fields in the interface, like the +log interface above that has the log level as a read/write parameter. + +See \ref spa_interface for some implementation details on interfaces. + + +# SPA Events + +Some interfaces will also allow you to register a callback (a hook or +listener) to be notified of events. This is usually when something +changed internally in the interface and it wants to notify the registered +listeners about this. + +For example, the `struct spa_node` interface has a method to register such +an event handler like this: + +\code{.c} +static void node_info(void *data, const struct spa_node_info *info) +{ + printf("got node info!\n"); +} + +static struct spa_node_events node_events = { + SPA_VERSION_NODE_EVENTS, + .info = node_info, +}; + +struct spa_hook listener; +spa_zero(listener); +spa_node_add_listener(node, &listener, &node_event, my_data); +\endcode + +You make a structure with pointers to the events you are interested in +and then use `spa_node_add_listener()` to register a listener. The +`struct spa_hook` is used by the interface to keep track of registered +event listeners. + +Whenever the node information is changed, your `node_info` method will +be called with `my_data` as the first data field. The events are usually +also triggered when the listener is added, to enumerate the current +state of the object. + +Events have a `version` field, set to `SPA_VERSION_NODE_EVENTS` in the +above example. It should contain the version of the event structure +you compiled with. When new events are added later, the version field +will be checked and the new signal will be ignored for older versions. + +You can remove your listener with: + +\code{.c} +spa_hook_remove(&listener); +\endcode + + +# API Results + +Some interfaces provide API that gives you a list or enumeration of +objects/values. To avoid allocation overhead and ownership problems, +SPA uses events to push results to the application. This makes it +possible for the plugin to temporarily create complex objects on the +stack and push this to the application without allocation or ownership +problems. The application can look at the pushed result and keep/copy +only what it wants to keep. + +## Synchronous Results + +Here is an example of enumerating parameters on a node interface. + +First install a listener for the result: + +\code{.c} +static void node_result(void *data, int seq, int res, + uint32_t type, const void *result) +{ + const struct spa_result_node_params *r = + (const struct spa_result_node_params *) result; + printf("got param:\n"); + spa_debug_pod(0, NULL, r->param); +} + +struct spa_hook listener = { 0 }; +static const struct spa_node_events node_events = { + SPA_VERSION_NODE_EVENTS, + .result = node_result, +}; + +spa_node_add_listener(node, &listener, &node_events, node); +\endcode + +Then perform the `enum_param` method: + +\code{.c} +int res = spa_node_enum_params(node, 0, SPA_PARAM_EnumFormat, 0, MAXINT, NULL); +\endcode + +This triggers the result event handler with a 0 sequence number for each +supported format. After this completes, remove the listener again: + +\code{.c} +spa_hook_remove(&listener); +\endcode + +## Asynchronous Results + +Asynchronous results are pushed to the application in the same way as +synchronous results, they are just pushed later. You can check that +a result is asynchronous by the return value of the enum function: + +\code{.c} +int res = spa_node_enum_params(node, 0, SPA_PARAM_EnumFormat, 0, MAXINT, NULL); + +if (SPA_RESULT_IS_ASYNC(res)) { + // result will be received later + ... +} +\endcode + +In the case of async results, the result callback will be called with the +sequence number of the async result code, which can be obtained with: + +\code{.c} +expected_seq = SPA_RESULT_ASYNC_SEQ(res); +\endcode + +# Implementing A New Plugin + +***FIXME*** + + + +\addtogroup spa_handle + +See: \ref page_spa_plugins + +*/ diff --git a/doc/dox/api/spa-pod.dox b/doc/dox/api/spa-pod.dox new file mode 100644 index 0000000..0bba2a4 --- /dev/null +++ b/doc/dox/api/spa-pod.dox @@ -0,0 +1,1034 @@ +/** \page page_spa_pod SPA POD + +\ref spa_pod (plain old data) is a sort of data container.

This makes it possible to skip over unknown +POD types. The POD start is always aligned to 8 bytes. + +POD's can be efficiently constructed and parsed in real-time threads without +requiring memory allocations. + +POD's use the SPA type system for the basic types and containers. See +the SPA types for more info. + + +# Types + +POD's can contain a number of basic SPA types: + +- `SPA_TYPE_None`: No value or a NULL pointer. +- `SPA_TYPE_Bool`: A boolean value. +- `SPA_TYPE_Id`: An enumerated value. +- `SPA_TYPE_Int`, `SPA_TYPE_Long`, `SPA_TYPE_Float`, `SPA_TYPE_Double`: + various numeral types, 32 and 64 bits. +- `SPA_TYPE_String`: A string. +- `SPA_TYPE_Bytes`: A byte array. +- `SPA_TYPE_Rectangle`: A rectangle with width and height. +- `SPA_TYPE_Fraction`: A fraction with numerator and denominator. +- `SPA_TYPE_Bitmap`: An array of bits. + +POD's can be grouped together in these container types: + +- `SPA_TYPE_Array`: An array of equal sized objects. +- `SPA_TYPE_Struct`: A collection of types and objects. +- `SPA_TYPE_Object`: An object with properties. +- `SPA_TYPE_Sequence`: A timed sequence of POD's. + +POD's can also contain some extra types: + +- `SPA_TYPE_Pointer`: A typed pointer in memory. +- `SPA_TYPE_Fd`: A file descriptor. +- `SPA_TYPE_Choice`: A choice of values. +- `SPA_TYPE_Pod`: A generic type for the POD itself. + + +# Constructing A POD + +A POD is usually constructed with a `struct spa_pod_builder`. The builder +needs to be initialized with a memory region to write into. It is +also possible to dynamically grow the memory as needed. + +The most common way to construct a POD is on the stack. This does +not require any memory allocations. The size of the POD can be +estimated pretty easily and if the buffer is not large enough, an +appropriate error will be generated. + +The code fragment below initializes a POD builder to write into +the stack allocated buffer. + +\code{.c} +uint8_t buffer[4096]; +struct spa_pod_builder b; +spa_pod_builder_init(&b, buffer, sizeof(buffer)); +\endcode + +Next we need to write some object into the builder. Let's write +a simple struct with an Int and Float in it. Structs are comparable +to JSON arrays. + +\code{.c} +struct spa_pod_frame f; +spa_pod_builder_push_struct(&b, &f); +\endcode + +First we open the struct container, the `struct spa_pod_frame` keeps +track of the container context. Next we add some values to +the container like this: + +\code{.c} +spa_pod_builder_int(&b, 5); +spa_pod_builder_float(&b, 3.1415f); +\endcode + +Then we close the container by popping the frame again: + +\code{.c} +struct spa_pod *pod; +pod = spa_pod_builder_pop(&b, &f); +\endcode + +`spa_pod_builder_pop()` returns a reference to the object we completed +on the stack. + +## Using varargs Builder + +We can also use the following construct to make POD objects: + +\code{.c} +spa_pod_builder_push_struct(&b, &f); +spa_pod_builder_add(&b, + SPA_POD_Int(5), + SPA_POD_Float(3.1415f)); +pod = spa_pod_builder_pop(&b, &f); +\endcode + +Or even shorter: + +\code{.c} +pod = spa_pod_builder_add_struct(&b, + SPA_POD_Int(5), + SPA_POD_Float(3.1415f)); +\endcode + +It's not possible to use the varargs builder to make a sequence or +array, use the normal builder methods for that. + +## Making Objects + +POD objects are containers for properties and are comparable to JSON +objects. + +Start by pushing an object: + +\code{.c} +spa_pod_builder_push_object(&b, &f, SPA_TYPE_OBJECT_Props, SPA_PARAM_Props); +\endcode + +An object requires an object type (`SPA_TYPE_OBJECT_Props`) and a context +ID (`SPA_PARAM_Props`). The object type defines the properties that can be +added to the object and their meaning. The SPA type system allows you to +make this connection (See the type system). + +Next we can push some properties in the object: + +\code{.c} +spa_pod_builder_prop(&b, SPA_PROP_device, 0); +spa_pod_builder_string(&b, "hw:0"); +spa_pod_builder_prop(&b, SPA_PROP_frequency, 0); +spa_pod_builder_float(&b, 440.0); +\endcode + +As can be seen, we always need to push a prop (with key and flags) +and then the associated value. For performance reasons it is a good +idea to always push (and parse) the object keys in ascending order. + +Don't forget to pop the result when the object is finished: + +\code{.c} +pod = spa_pod_builder_pop(&b, &f); +\endcode + +There is a shortcut for making objects: + +\code{.c} +pod = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Props, SPA_PARAM_Props, + SPA_PROP_device, SPA_POD_String("hw:0"), + SPA_PROP_frequency, SPA_POD_Float(440.0f)); +\endcode + +## Choice Values + +It is possible to express ranges or enumerations of possible +values for properties (and to some extend structs). This is achieved +with choice values. + +Choice values are really just a choice type and an array of choice values +(of the same type). Depending on the choice type, the array values are +interpreted in different ways: + +- `SPA_CHOICE_None`: No choice, first value is current. +- `SPA_CHOICE_Range`: Range: default, min, max. +- `SPA_CHOICE_Step`: Range with step: default, min, max, step. +- `SPA_CHOICE_Enum`: Enum: default, alternative,... +- `SPA_CHOICE_Flags`: Bitmask of flags. + +Let's illustrate this with a props object that specifies a range of +possible values for the frequency: + +\code{.c} +struct spa_pod_frame f2; + +spa_pod_builder_push_object(&b, &f, SPA_TYPE_OBJECT_Props, SPA_PARAM_Props); +spa_pod_builder_prop(&b, SPA_PROP_frequency, 0); +spa_pod_builder_push_choice(&b, &f2, SPA_CHOICE_Range, 0); +spa_pod_builder_float(&b, 440.0); // default +spa_pod_builder_float(&b, 110.0); // min +spa_pod_builder_float(&b, 880.0); // min +pod = spa_pod_builder_pop(&b, &f2); +pod = spa_pod_builder_pop(&b, &f); +\endcode + +As you can see, first push the choice as a range, then the values. A range +choice expects at least three values, the default value, minimum and maximum +values. There is a shortcut for this as well using varargs: + +\code{.c} +pod = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Props, SPA_PARAM_Props, + SPA_PROP_frequency, SPA_POD_CHOICE_RANGE_Float(440.0f, 110.0f, 880.0f)); +\endcode + +## Choice Examples + +This is a description of a possible `SPA_TYPE_OBJECT_Format` as used when +enumerating allowed formats (`SPA_PARAM_EnumFormat`) in SPA objects: + +\code{.c} +pod = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Format, SPA_PARAM_EnumFormat, + // specify the media type and subtype + SPA_FORMAT_mediaType, SPA_POD_Id(SPA_MEDIA_TYPE_audio), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(SPA_MEDIA_SUBTYPE_raw), + // audio/raw properties + SPA_FORMAT_AUDIO_format, SPA_POD_CHOICE_ENUM_Id(4, // 4 values follow + SPA_AUDIO_FORMAT_S16, // default + SPA_AUDIO_FORMAT_S16, // alternative1 + SPA_AUDIO_FORMAT_S32, // alternative2 + SPA_AUDIO_FORMAT_F32 // alternative3 + ), + SPA_FORMAT_AUDIO_rate, SPA_POD_CHOICE_RANGE_Int( + 44100, // default + 8000, // min + 192000 // max + ), + SPA_FORMAT_AUDIO_channels, SPA_POD_Int(2)); +\endcode + +## Fixate + +We can remove all choice values from the object with the +`spa_pod_object_fixate()` method. This modifies the pod in-place and sets all +choice properties to `SPA_CHOICE_None`, forcing the default value as the +only available value in the choice. + +Running fixate on our previous example would result in an object equivalent +to: + +\code{.c} +pod = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Format, SPA_PARAM_EnumFormat, + // specify the media type and subtype + SPA_FORMAT_mediaType, SPA_POD_Id(SPA_MEDIA_TYPE_audio), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(SPA_MEDIA_SUBTYPE_raw), + // audio/raw properties + SPA_FORMAT_AUDIO_format, SPA_POD_Id(SPA_AUDIO_FORMAT_S16), + SPA_FORMAT_AUDIO_rate, SPA_POD_Int(44100), + SPA_FORMAT_AUDIO_channels, SPA_POD_Int(2)); +\endcode + + +# Parsing A POD + +Parsing a POD usually consists of: + +- Validating if raw bytes + size can contain a valid POD. +- Inspecting the type of a POD. +- Looping over the items in an object or struct. +- Getting data out of POD's. + +## Validating Bytes + +Use `spa_pod_from_data()` to check if maxsize of bytes in data contain +a POD at the size bytes starting at offset. This function checks that +the POD size will fit and not overflow. + +\code{.c} +struct spa_pod *pod; +pod = spa_pod_from_data(data, maxsize, offset, size); +\endcode + +## Checking The Type Of POD + +Use one of `spa_pod_is_bool()`, `spa_pod_is_int()`, etc to check +for the type of the pod. For simple (non-container) types, +`spa_pod_get_bool()`, `spa_pod_get_int()` etc can be used to +extract the value of the pod. + +`spa_pod_is_object_type()` can be used to check if the POD contains +an object of the expected type. + +## Struct Fields + +To iterate over the fields of a struct use: + +\code{.c} +struct spa_pod *pod, *obj; +SPA_POD_STRUCT_FOREACH(obj, pod) { + printf("field type:%d\n", pod->type); +} +\endcode + +For parsing structs it is usually much easier to use the parser +below. + +## Object Properties + +To iterate over the properties in an object you can do: + +\code{.c} +struct spa_pod_prop *prop; +struct spa_pod_object *obj = (struct spa_pod_object*)pod; +SPA_POD_OBJECT_FOREACH(pod, prop) { + printf("prop key:%d\n", prop->key); +} +\endcode + +There is a function to retrieve the property for a certain key +in the object. If the properties of the object are in ascending +order, you can start searching from the previous key. + +\code{.c} +struct spa_pod_prop *prop; +prop = spa_pod_find_prop(obj, NULL, SPA_FORMAT_AUDIO_format); + // .. use first prop +prop = spa_pod_find_prop(obj, prop, SPA_FORMAT_AUDIO_rate); + // .. use next prop +\endcode + +## Parser + +Similar to the builder, there is a parser object as well. + +If the fields in a struct are known, it is much easier to use the +parser. Similarly, if the object type (and thus its keys) are known, +the parser is easier. + +First initialize a `struct spa_pod_parser`: + +\code{.c} +struct spa_pod_parser p; +spa_pod_parser_pod(&p, obj); +\endcode + +You can then enter containers such as objects or structs with a push +operation: + +\code{.c} +struct spa_pod_frame f; +spa_pod_parser_push_struct(&p, &f); +\endcode + +You need to store the context in a `struct spa_pod_frame` to be able +to exit the container again later. + +You can then parse each field. The parser takes care of moving to the +next field. + +\code{.c} +uint32_t id, val; +spa_pod_parser_get_id(&p, &id); +spa_pod_parser_get_int(&p, &val); +... +\endcode + +And finally exit the container again: + +\code{.c} +spa_pod_parser_pop(&p, &f); +\endcode + +## Parser With Variable Arguments + +In most cases, parsing objects is easier with the variable argument +functions. The parse function look like the mirror image of the builder +functions. + +To parse a struct: + +\code{.c} +spa_pod_parser_get_struct(&p, + SPA_POD_Id(&id), + SPA_POD_Int(&val)); +\endcode + +To parse properties in an object: + +\code{.c} +uint32_t id, type, subtype, format, rate, channels; +spa_pod_parser_get_object(&p, + SPA_TYPE_OBJECT_Format, &id, + SPA_FORMAT_mediaType, SPA_POD_Id(&type), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(&subtype), + SPA_FORMAT_AUDIO_format, SPA_POD_Id(&format), + SPA_FORMAT_AUDIO_rate, SPA_POD_Int(&rate), + SPA_FORMAT_AUDIO_channels, SPA_POD_Int(&channels)); +\endcode + +When parsing objects it is possible to have optional fields. You can +make a field optional be parsing it with the `SPA_POD_OPT_` prefix +for the type. + +In the next example, the rate and channels fields are optional +and when they are not present, the variables will not be changed. + +\code{.c} +uint32_t id, type, subtype, format, rate = 0, channels = 0; +spa_pod_parser_get_object(&p, + SPA_TYPE_OBJECT_Format, &id, + SPA_FORMAT_mediaType, SPA_POD_Id(&type), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(&subtype), + SPA_FORMAT_AUDIO_format, SPA_POD_Id(&format), + SPA_FORMAT_AUDIO_rate, SPA_POD_OPT_Int(&rate), + SPA_FORMAT_AUDIO_channels, SPA_POD_OPT_Int(&channels)); +\endcode + +It is not possible to parse a sequence or array with the parser. +Use the iterator for this. + +## Choice Values + +The parser will handle choice values as long as they are of type +`none`. It will then parse the single value from the choice. When +dealing with other choice values, it's possible to parse the +property values into a `struct spa_pod` and then inspect the choice +manually, if needed. + +Here is an example of parsing the format values as a POD: + +\code{.c} +uint32_t id, type, subtype; +struct spa_pod *format; +spa_pod_parser_get_object(&p, + SPA_TYPE_OBJECT_Format, &id, + SPA_FORMAT_mediaType, SPA_POD_Id(&type), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(&subtype), + SPA_FORMAT_AUDIO_format, SPA_POD_Pod(&format)); +\endcode + +`spa_pod_get_values()` is a useful function. It returns a +`struct spa_pod*` with and array of values. For normal POD's +and choice none values, it simply returns the POD and one value. +For other choice values it returns the choice type and an array +of values: + +\code{.c} +struct spa_pod *value; +uint32_t n_vals, choice; + +value = spa_pod_get_values(pod, &n_vals, &choice); + +switch (choice) { +case SPA_CHOICE_None: + // one single value + break; +case SPA_CHOICE_Range: + // array of values of type of pod, cast to right type + // to iterate. + uint32_t *v = SPA_POD_BODY(values); + if (n_vals < 3) + break; + printf("default value: %u\n", v[0]); + printf("min value: %u\n", v[1]); + printf("max value: %u\n", v[2]); + break; + + // ... +default: + break; +} +\endcode + + +# Filter + +Given two POD objects of the same type (object, struct, ..) one can +run a filter and generate a new POD that only contains values that +are compatible with both input POD's. + +This is, for example, used to find a compatible format between two ports. + +As an example we can run a filter on two simple POD's: + +\code{.c} +pod = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Format, SPA_PARAM_EnumFormat, + SPA_FORMAT_mediaType, SPA_POD_Id(SPA_MEDIA_TYPE_audio), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(SPA_MEDIA_SUBTYPE_raw), + SPA_FORMAT_AUDIO_format, SPA_POD_CHOICE_ENUM_Id(4, // 4 values follow + SPA_AUDIO_FORMAT_S16, // default + SPA_AUDIO_FORMAT_S16, // alternative1 + SPA_AUDIO_FORMAT_S32, // alternative2 + SPA_AUDIO_FORMAT_F32 // alternative3 + )); + +filter = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Format, SPA_PARAM_EnumFormat, + SPA_FORMAT_mediaType, SPA_POD_Id(SPA_MEDIA_TYPE_audio), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(SPA_MEDIA_SUBTYPE_raw), + SPA_FORMAT_AUDIO_format, SPA_POD_CHOICE_ENUM_Id(3, // 3 values follow + SPA_AUDIO_FORMAT_S16, // default + SPA_AUDIO_FORMAT_S16, // alternative1 + SPA_AUDIO_FORMAT_F64 // alternative2 + )); + +struct spa_pod *result; +if (spa_pod_filter(&b, &result, pod, filter) < 0) + goto exit_error; +\endcode + +Filter will contain a POD equivalent to: + +\code{.c} +result = spa_pod_builder_add_object(&b, + SPA_TYPE_OBJECT_Format, SPA_PARAM_EnumFormat, + SPA_FORMAT_mediaType, SPA_POD_Id(SPA_MEDIA_TYPE_audio), + SPA_FORMAT_mediaSubtype, SPA_POD_Id(SPA_MEDIA_SUBTYPE_raw), + SPA_FORMAT_AUDIO_format, SPA_AUDIO_FORMAT_S16); +\endcode + +# POD Layout + +A POD always starts with a size/type pair of uint32_t in native endianness, +followed by size in bytes of the payload data and padding.

The adapter +performs sample format, sample rate and channel mixing operations. + +All properties listed below are node properties. + +## Merger Parameters + +The merger is used as the input for a sink device node or a capture stream. It takes the various channels and merges them into a single stream for further processing. + +The merger will also provide the monitor ports of the input channels and can +apply a software volume on the monitor signal. + +@PAR@ node-prop monitor.channel-volumes = false +The volume of the input channels is applied to the volume of the monitor ports. Normally +the monitor ports expose the raw unmodified signal on the input ports. + +## Resampler Parameters + +Source, sinks, capture and playback streams contain a high quality adaptive resampler. +It uses [sinc](https://ccrma.stanford.edu/~jos/resample/resample.pdf) based resampling +with linear interpolation of filter banks to perform arbitrary +resample factors. The resampler is activated in the following cases: + +* The hardware of a device node does not support the graph samplerate. Resampling will occur + from the graph samplerate to the hardware samplerate. +* The hardware clock of a device does not run at the same speed as the graph clock and adaptive + resampling is required to match the clocks. +* A stream does not have the same samplerate as the graph and needs to be resampled. +* An application wants to activate adaptive resampling in a stream to make it match some other + clock. + +PipeWire performs most of the sample conversions and resampling in the client (Or in the case of the PulseAudio server, in the pipewire-pulse server that creates the streams). This ensures all the conversions are offloaded to the clients and the server can deal with one single format for performance reasons. + +Below is an explanation of the options that can be tuned in the sample converter. + +@PAR@ node-prop resample.quality = 4 +\parblock +The quality of the resampler. from 0 to 14, the default is 4. + +Increasing the quality will result in better cutoff and less aliasing at the expense of +(much) more CPU consumption. The default quality of 4 has been selected as a good compromise +between quality and performance with no artifacts that are well below the audible range. + +See [Infinite Wave](https://src.infinitewave.ca/) for a comparison of the performance. +\endparblock + +@PAR@ node-prop resample.disable = false +Disable the resampler entirely. The node will only be able to negotiate with the graph +when the samplerates are compatible. + +## Channel Mixer Parameters + +Source, sinks, capture and playback streams can apply channel mixing on the incoming signal. + +Normally the channel mixer is not used for devices, the device channels are usually exposed as they are. This policy is usually enforced by the session manager, so we refer to its documentation there. + +Playback and capture streams are usually configured to the channel layout of the sink/source +they connect to and will thus perform channel mixing. + +The channel mixer also implements a software volume. This volume adjustment is performed on the original +channel layout. ex: A stereo playback stream that is up-mixed to 5.1 has 2 a left an right volume control. + +@PAR@ node-prop channelmix.disable = false +Disables the channel mixer completely. The stream will only be able to link to compatible +sources/sinks with the exact same channel layout. + +@PAR@ node-prop channelmix.min-volume = 0.0 +@PAR@ node-prop channelmix.max-volume = 10.0 +Gives the min and max volume values allowed. Any volume that is set will be clamped to these +values. + +@PAR@ node-prop channelmix.normalize = false +\parblock +Makes sure that during such mixing & resampling original 0 dB level is preserved, so nothing sounds wildly quieter/louder. + +While this options prevents clipping, it can in some cases produce too low volume. Increase the +volume in that case or disable normalization. +\endparblock + +@PAR@ node-prop channelmix.lock-volumes = false +Completely disable volume or mute changes. Defaults to false. + +@PAR@ node-prop channelmix.mix-lfe = true +Mixes the low frequency effect channel into the front center or stereo pair. This might enhance the dynamic range of the signal if there is no subwoofer and the speakers can reproduce the low frequency signal. + +@PAR@ node-prop channelmix.upmix = true +\parblock +Enables up-mixing of the front center (FC) when the target has a FC channel. +The sum of the stereo channels is used and an optional lowpass filter can be used +(see `channelmix.fc-cutoff`). + +Also enabled up-mixing of LFE when `channelmix.lfe-cutoff` is set to something else than 0 and +the target has an LFE channel. The LFE channel is produced by adding the stereo channels. + +If `channelmix.upmix` is true, the up-mixing of the rear channels is also enabled and controlled +with the `channelmix-upmix-method` property. +\endparblock + +@PAR@ node-prop channelmix.upmix-method = psd +\parblock +3 methods are provided to produce the rear channels in a surround sound: + +1. none.

The rear channels as produced from the front left and right ambient sound (the +difference between the channels). A delay and optional phase shift are added to the rear signal +to make the sound bigger. +\endparblock + +@PAR@ node-prop channelmix.lfe-cutoff = 150 +Apply a lowpass filter to the low frequency effects. The value is expressed in Hz. Typical subwoofers have a cutoff at around 150 and 200. The default value of 0 disables the feature. + +@PAR@ node-prop channelmix.fc-cutoff = 12000 +\parblock +Apply a lowpass filter to the front center frequency. The value is expressed in Hz. + +Since the front center contains the dialogs, a typical cutoff frequency is 12000 Hz. + +This option is only active when the up-mix is enabled. +\endparblock + +@PAR@ node-prop channelmix.rear-delay = 12.0 +\parblock +Apply a delay in milliseconds when up-mixing the rear channels. This improves +specialization of the sound. A typical delay of 12 milliseconds is the default. + +This is only active when the `psd` up-mix method is used. +\endparblock + +@PAR@ node-prop channelmix.stereo-widen = 0.0 +\parblock +Subtracts some of the front center signal from the stereo channels. This moves the dialogs +more to the center speaker and leaves the ambient sound in the stereo channels. + +This is only active when up-mix is enabled and a Front Center channel is mixed. +\endparblock + +@PAR@ node-prop channelmix.hilbert-taps = 0 +\parblock +This option will apply a 90 degree phase shift to the rear channels to improve specialization. +Taps needs to be between 15 and 255 with more accurate results (and more CPU consumption) +for higher values. + +This is only active when the `psd` up-mix method is used. +\endparblock + +@PAR@ node-prop dither.noise = 0 +\parblock +This option will add N bits of random data to the signal. When no dither.method is +specified, the random data will flip between [-(1<<(N-1)), 0] every 1024 samples. With +a dither.method, the dither noise is amplified with 1<<(N-1) bits. + +This can be used to keep some amplifiers alive during silent periods. One or two bits of noise is +usually enough, otherwise the noise will become audible. This is usually used together with +`session.suspend-timeout-seconds` to disable suspend in the session manager. + +Note that PipeWire uses floating point operations with 24 bits precission for all of the audio +processing. Conversion to 24 bits integer sample formats is lossless and conversion to 32 bits +integer sample formats are simply padded with 0 bits at the end. This means that the dither noise +is always only in the 24 most significant bits. +\endparblock + +@PAR@ node-prop dither.method = none +\parblock +Optional [dithering](https://en.wikipedia.org/wiki/Dither) can be done on the quantized +output signal. + +There are 6 modes available: + +1. none No dithering is done. +2. rectangular Dithering with a rectangular noise distribution. This adds random + bits in the [-0.5, 0.5] range to the signal with even distribution. +3. triangular Dithering with a triangular noise distribution.

The matches key is used to +define the conditions that need to be met for the rule to be evaluated as true, and the actions +key is used to define the actions that are performed when the rule is evaluated as true. + +The matches key is always a JSON array of objects, where each object defines a condition that needs +to be met. Each condition is a list of key-value pairs, where the key is the name of the property +that is being matched, and the value is the value that the property needs to have. Within a condition, +all the key-value pairs are combined with a logical AND, and all the conditions in the matches +array are combined with a logical OR. + +The actions key is always a JSON object, where each key-value pair defines an action that is +performed when the rule is evaluated as true. The action name is specific to the rule and is +defined by the rule’s documentation, but most frequently you will see the update-props action, +which is used to update the properties of the matched object. + +In the matches array, it is also possible to use regular expressions to match property values. +For example, to match all nodes with a name that starts with my_, you can use the following condition: + +```css +matches = [ + { + node.name = "~my_.*" + } +] +``` + +The ~ character signifies that the value is a regular expression. The exact syntax of the regular +expressions is the POSIX extended regex syntax, as described in the regex (7) man page. + +In addition to regular expressions, you may also use the ! character to negate a condition. For +example, to match all nodes with a name that does not start with my_, you can use the following condition: + +```css +matches = [ + { + node.name = "!~my_.*" + } +] +``` + +The ! character can be used with or without a regular expression. For example, to match all +nodes with a name that is not equal to my_node, you can use the following condition: + +```css +matches = [ + { + node.name = "!my_node" + } +] +``` + +The null value has a special meaning; it checks if the property is not available +(or unset). To check if a property is not set: + +```css +matches = [ + { + node.name = null + } +] +``` + +To check the existence of a property, one can use the !null condition, for example: + +```css +matches = [ + { + node.name = "!null" + } + { + node.name = !null # simplified syntax + } +] +``` +To handle the "null" string, one needs to escape the string. For example, to check +if a property has the string value "null", use: + +```css +matches = [ + { + node.name = "null" + } +] +``` +To handle anything but the "null" string, use: + +```css +matches = [ + { + node.name = "!\"null\"" + } + { + node.name = !"null" # simplified syntax + } +] +``` + + +# CONTEXT PROPERTIES RULES @IDX@ pipewire.conf + +`context.properties.rules` can be used to dynamically update the properties +based on other properties. + +A typical case is to update custom settings when running inside a VM. +The `cpu.vm.name` is automatically set when running in a VM with the name of +the VM.

This will retrigger the `param_changed` event with an + \ref SPA_PARAM_Format as described below. + If the \ref SPA_PARAM_Format contains a modifier key, without the flag + \ref SPA_POD_PROP_FLAG_DONT_FIXATE, it should only contain one value in the + \ref SPA_CHOICE_Enum. In this case announce the \ref SPA_PARAM_Buffers accordingly + to the selected format and modifier. It is important to query the plane count + of the used format modifier pair and set `SPA_PARAM_BUFFERS_blocks` accordingly. + You might also want to add the option of adding explicit sync support to the + buffers, as explained below. + +Note: When test allocating a buffer, collect all possible modifiers, while omitting +`DRM_FORMAT_MOD_INVALID` from the \ref SPA_FORMAT_VIDEO_modifier property and +pass them all to the graphics API. If the allocation fails and the list of +possible modifiers contains `DRM_FORMAT_MOD_INVALID`, fall back to allocating +without an explicit modifier if the graphics API allows it. + +## add_buffer Hook + +This is relevant for producers. + +Allocate a DMA-BUF only using the negotiated format and modifier. + +## on_event Hook + +This is relevant for consumers. + +Check the type of the dequeued buffer.

Note: that the n_datas +might also contain extra fds for things like sync_timelime metadata, you need +to take this into account when persing the planes. + +Note: Some graphics APIs have separated functions for the modifier-less case +(`DRM_FORMAT_MOD_INVALID`) or are omitting the modifier, since it might be used +for error handling. + +## Example Programs + +- \ref video-src-fixate.c "": \snippet{doc} video-src-fixate.c title +- \ref video-play-fixate.c "": \snippet{doc} video-play-fixate.c title + +# DMA-BUF Mapping Warning + +It's important to make sure all consumers of the PipeWire stream are prepared +to deal with DMA-BUFs. Most DMA-BUFs cannot be treated like shared memory in general +because of the following issues: + +- DMA-BUFs can use hardware-specific tiling and compression as described by + modifiers. Thus, a `mmap(3)` on the DMA-BUF FD will not give a linear view of + the buffer contents. +- DMA-BUFs need to be properly synchronized with the asynchronous reads and + writes of the hardware. A `mmap(3)` call is not enough to guarantee proper + synchronization. (Maybe add link to linux syscall doc??) +- Blindly accessing the DMA-BUFs via `mmap(3)` can be extremely slow if the + buffer has been allocated on discrete hardware. Consumers are better off + using a proper graphics API (such as EGL, Vulkan or VA-API) to process the + DMA-BUFs. + +# Size of DMA-BUFs + +When importing a DMA-BUF with a proper graphics API the size of a single buffer plane +is no relevant property since it will be derived by the driver from the other properties. +Therefore consumers should ignore the field `maxsize` of a `spa_data` and the field +`size` of a `spa_chunk` struct. Producers are allowed to set both to 0. +In cases where mapping a single plane is required the size should be obtained locally +via the filedescriptor. + +# SPA param video format helpers + +SPA offers helper functions to parse and build a spa_pod object to/from the spa_video_info_* +struct. The flags \ref SPA_VIDEO_FLAG_MODIFIER and \ref SPA_VIDEO_FLAG_MODIFIER_FIXATION_REQUIRED +are used to indicate modifier usage with the format. `SPA_VIDEO_FLAG_MODIFIER` declares the +parsed/provided spa_video_info_* struct contains valid modifier information. For legacy +reasons `spa_format_video_*_build` will announce any modifier != 0 even when this flag is +unused. `SPA_VIDEO_FLAG_MODIFIER_FIXATION_REQUIRED` is exclusive to the parse helpers and +declares that the parsed spa_pod contains modifier information which needs to be fixated as +described above. The list of available modifiers has to be parsed manually from the spa_pod +object. + +- \ref spa_video_info_raw, \ref spa_format_video_raw_parse, \ref spa_format_video_raw_build +- \ref spa_video_info_dsp, \ref spa_format_video_dsp_parse, \ref spa_format_video_dsp_build + +# v4l2 + +Another use case for streaming via DMA-BUFs are exporting a camera feed from v4l2 +as DMA-BUFs.

An implementation of a graph based media processing engine. +2. An asynchronous IPC mechanism to manipulate and introspect + a graph in another process. + +There is usually a daemon that implements the global graph and +clients that operate on this graph. + +The IPC mechanism in PipeWire is inspired by Wayland in that it +follows the same design principles of objects and methods/events +along with how this API is presented to the user. + +PipeWire has a plugin architecture that allows new features to +be added (or removed) by the user. Plugins can hook into many +aspects of PipeWire and change the behaviour or number of +features dynamically. + + +# Principles + +The PipeWire API is an object oriented asynchronous protocol. +All requests and replies are method invocations on some object. + +Objects are identified with a unique ID. Each object implements an +interface and requests result in invocations of methods on the +interface. + +The protocol is message based. A message sent by a client to the +server is called a method. A message from the server to the client +is called an event. Unlike Wayland, these messages are not (yet) +described in an external protocol file but implemented directly in +a protocol plugin. Protocol plugins can be added to add new +objects or even protocols when required. + +Messages are encoded with \ref page_spa_pod, which make it +possible to encode complex objects with right types. + +Events from the server can be a reply to a method or can be emitted +when the server state changes. + +Upon connecting to a server, it will broadcast its state. Clients +should listen for these state changes and cache them. There is no +need (or mechanism) to query the state of the server. + +The server also has a registry object that, when listening to, +will broadcast the presence of global objects and any changes in +their state. + +State about objects can be obtained by binding to them and listening +for state changes. + + +# Versioning + +All interfaces have a version number. The maximum supported version +number of an interface is advertised in the registry global event. + +A client asks for a specific version of an interface when it binds +to them. It is the task of the server to adapt to the version of the +client. + +Interfaces increase their version number when new methods or events +are added. Methods or events should never be removed or changed for +simplicity. + + +# Proxies and Resources + +When a client connects to a PipeWire daemon, a new `struct pw_proxy` +object is created with ID 0. The `struct pw_core` interface is +assigned to the proxy. + +On the server side there is an equivalent `struct pw_resource` with +ID 0. Whenever the client sends a message on the proxy (by calling +a method on the interface of the proxy) it will transparently result +in a callback on the resource with the same ID. + +Likewise if the server sends a message (an event) on a resource, it +will result in an event on the client proxy with the same ID. + +PipeWire will notify a client when a resource ID (and thus also proxy +ID) becomes unused. The client is responsible for destroying the +proxy when it no longer wants to use it. + + +# Interfaces + +## struct pw_loop + +An abstraction for a `poll(2)` loop. It is usually part of one of: + +- `struct pw_main_loop`: A helper that can run and stop a `pw_loop`. +- `struct pw_thread_loop`: A helper that can run and stop a `pw_loop` + in a different thread. It also has some helper + functions for various thread related synchronization + issues. +- `struct pw_data_loop`: A helper that can run and stop a `pw_loop` + in a real-time thread along with some useful helper + functions. + +## struct pw_context + +The main context for PipeWire resources. It keeps track of the mainloop, +loaded modules, the processing graph and proxies to remote PipeWire +instances. + +An application has to select an implementation of a `struct pw_loop` +when creating a context. + +The context has methods to create the various objects you can use to +build a server or client application. + +## struct pw_core + +A proxy to a remote PipeWire instance. This is used to send messages +to a remote PipeWire daemon and to receive events from it. + +A core proxy can be used to receive errors from the remote daemon +or to perform a roundtrip message to flush out pending requests. + +Other core methods and events are used internally for the object +life cycle management. + +## struct pw_registry + +A proxy to a PipeWire registry object. It emits events about the +available objects on the server and can be used to bind to those +objects in order to call methods or receive events from them. + +## struct pw_module + +A proxy to a loadable module. Modules implement functionality such +as provide new objects or policy. + +## struct pw_factory + +A proxy to an object that can create other objects. + +## struct pw_device + +A proxy to a device object. Device objects model a physical hardware +or software device in the system and can create other objects +such as nodes or other devices. + +## struct pw_node + +A Proxy to a processing node in the graph. Nodes can have input and +output ports and the ports can be linked together to form a graph. + +## struct pw_port + +A Proxy to an input or output port of a node. They can be linked +together to form a processing graph. + +## struct pw_link + +A proxy to a link between in output and input port. A link negotiates +a format and buffers between ports. A port can be linked to many other +ports and PipeWire will manage mixing and duplicating the buffers. + + +# High Level Helper Objects + +Some high level objects are implemented to make it easier to interface +with a PipeWire graph. + +## struct pw_filter + +A `struct pw_filter` allows you implement a processing filter that can +be added to a PipeWire graph. It is comparable to a JACK client. + +## struct pw_stream + +A `struct pw_stream` makes it easy to implement a playback or capture +client for the graph. It takes care of format conversion and buffer +sizes. It is comparable to Core Audio AudioQueue or a PulseAudio +stream. + + +# Security + +With the default native protocol, clients connect to PipeWire using +a named socket. This results in a client socket that is used to +send messages. + +For sandboxed clients, it is possible to get the client socket via +other ways, like using the portal. In that case, a portal will +do the connection for the client and then hands the connection socket +to the client. + +All objects in PipeWire have per client permission bits, currently +READ, WRITE, EXECUTE and METADATA. A client can not see an object +unless it has READ permissions. Similarly, a client can only execute +methods on an object when the EXECUTE bit is set and to modify the +state of an object, the client needs WRITE permissions. + +A client (the portal after it makes a connection) can drop permissions +on an object. Once dropped, it can never reacquire the permission. + +Clients with WRITE/EXECUTE permissions on another client can +add and remove permissions for the client at will. + +Clients with MODIFY permissions on another object can set or remove +metadata on that object. + +Clients that need permissions assigned to them can be started in +blocked mode and resume when permissions are assigned to them by +a session manager or portal, for example. + +PipeWire uses memfd (`memfd_create(2)`) or DMA-BUF for sharing media +and data between clients. Clients can thus not look at other clients +data unless they can see the objects and connect to them. + + +# Implementation + +PipeWire also exposes an API to implement the server side objects in +a graph. + + +# Error Reporting + +Functions return either NULL with errno set or a negative int error +code when an error occurs.

An endpoint may be backed by several nodes or no nodes at all. +Different endpoints may also be sharing nodes in some cases. + +An endpoint that does not map to any node may be useful to represent hardware +that the session manager needs to be able to control, but there is no way +to route media to/from that hardware through the PipeWire media graph. For +example, in a car we may have a CD player device that is directly wired to the +speakers amplifier and therefore audio flows between them without passing +through the controlling CPU. However, it is useful for the session manager to +be able to represent the *CD player endpoint* and the _endpoint link_ between +it and the amplifier, so that it can apply audio policy that takes into account +whether the CD player is playing or not. + +### Target + +An **endpoint** may be grouping together targets that can be reached by +following the same route and they are mutually exclusive with each other. + +For example, the speakers and the headphones jack on a laptop are usually +mutually exclusive by hardware design (hardware mutes the speakers when the +headphones are enabled) and they share the same ALSA PCM device, so audio still +follows the same route to reach both. + +In this case, a session manager may choose to group these two targets into the +same endpoint, using a parameter on the _endpoint_ object to allow the user +to choose the target (if the hardware allows configuring this at all). + +## Endpoint Stream + +An **endpoint stream** is attached to an **endpoint** and represents a logical +path that can be taken to reach this endpoint, often associated with +a _use case_. + +For example, the "Speakers amplifier" endpoint in a car might have the +following streams: + +- _Music_: A path to play music; + the implementation will output this to all speakers, using the volume + that has been configured for the "Music" use case. +- _Voice_: A path to play a voice message; such as a navigation message or + feedback from a voice assistant, the implementation will output this + to the front speakers only. Lowering the volume of the music (if any) + on these speakers at the same time. +- _Emergency_: A path to play an emergency situation sound (a beep, + or equivalent); the implementation will output this on all speakers. + Increasing the volume to a factory defined value if necessary (to ensure + that it is audible) while muting audio from all other streams at the + same time. + +In another example, a microphone that can be used for activating a voice +assistant might have the following streams: + +- _Capture_: A path to capture directly from the microphone; this can be used + by an application that listens for the assistant's wake-word in order + to activate the full voice recognition engine. +- _CaptureDelayed_: A path to capture with a constant delay (meaning that + starting capturing now will actually capture something that was spoken + a little earlier); this can be used by the full voice recognition engine, + allowing it to start after the wake-word has been spoken while capturing + audio that also includes the wake-word. + +Endpoint streams may be mutually exclusive or they may used simultaneously, +depending on the implementation. + +Endpoint streams may be implemented in many ways: + +- By plugging additional nodes in the media graph that link to the device node + (ex. a simple buffering node linked to an alsa source node could implement + the _CaptureDelayed_ stream in the above microphone example). +- By using a different device node (ex. different ALSA device on the same card) + that has a special meaning for the hardware. +- By triggering switches on the hardware (ex. modify ALSA controls on the + same device). + +## Endpoint Link + +An **endpoint link** connects two streams from two different endpoints, creating +a logical representation of media flow between the endpoints. + +An **endpoint link** may be implemented by creating one or more _links_ in the +underlying media graph, or it may be implemented by configuring hardware +resources to enable media flow, in case the flow does not pass through the +media graph. + +### Constructing + +Constructing an **endpoint link** is done by asking the _endpoint stream_ +objects to prepare it.

Some nodes hold a link to other +nodes. + +It is possible that the driver is the same as a node in the graph (for example node A) +but conceptually, the links above are still valid. + +The driver will then start processing the graph by emitting the ready signal. PipeWire +will then: + + - Check the previous cycle. Did it complete? Mark xrun on unfinished nodes. + - Perform reposition requests if any, timebase changes, etc.. + - The pending counter of each follower node is set to the required field. + - It then loops over all targets of the driver and atomically decrements the required + field of the activation record. When the required field is 0, the eventfd is signaled + and the node can be scheduled. + +In our example above, Node A and B will have their pending state decremented. Node A +will be 0 and will be triggered first (node B has 2 pending dependencies to start with and +will not be triggered yet). The driver itself also has 2 dependencies left and will not +be triggered (complete) yet. + +## Scheduling node A + +When the eventfd is signaled on a node, we say the node is triggered and it will be able +to process data. It consumes the input on the input ports and produces more data on the +output ports. + +After processing, node A goes through the list of targets and decrements each pending +field (node A has a reference to B and the driver). + +In our above example, the driver is decremented (from 2 to 1) but is not yet triggered. +node B is decremented (from 1 to 0) and is triggered by writing to the eventfd. + +## Scheduling node B + +Node B is scheduled and processes the input from node A. It then goes through the list of +targets and decrements the pending fields. It decrements the pending field of the +driver (from 1 to 0) and triggers the driver. + +## Scheduling the driver + +The graph always completes after the driver is triggered and scheduled. All required +fields from all the nodes in the target list of the driver are now 0. + +The driver calculates some stats about cpu time etc. + +# Remote nodes. + +For remote nodes, the eventfd and the activation is transferred from the server +to the client. + +This means that writing to the remote client eventfd will wake the client directly +without going to the server first. + +All remote clients also get the activation and eventfd of the peer and driver they +are linked to and can directly trigger peers and drivers without going to the +server first. + +## Remote driver nodes. + +Remote drivers start the graph cycle directly without going to the server first. + +After they complete (and only when the profiler is active), they will trigger an +extra eventfd to signal the server that the graph completed. This is used by the +server to generate the profiler info. + +## Lazy scheduling + +Normally, a driver will wake up the graph and all the followers need to process +the data in sync. There are cases where: + + 1. the follower might not be ready to process the data + 2. the driver rate is not ideal, the follower rate is better + 3. the driver might not know when new data is available in the follower and + might wake up the graph too often. + +In these cases, the driver and follower roles need to be reversed and a mechanism +needs to be provided so that the follower can know when it is worth processing the +graph. + +For notifying when the graph is ready to be processed, (non driver) nodes can send +a RequestProcess event which will arrive as a RequestProcess command in the driver. +The driver can then decide to run the graph or not. + +When the graph is started or partially controlled by RequestProcess events and +commands we say we have lazy scheduling. The driver is not always scheduling according +to its own rhythm but also depending on the follower. + +We can't just enable lazy scheduling when no follower will emit RequestProcess events +or when no driver will listen for RequestProcess commands.

This results in JACK clients being redirected to PipeWire. + +Other nodes are implemented by PipeWire clients. + +## The PipeWire clients + +PipeWire clients can be any process. +They can speak to the PipeWire server through a UNIX domain socket using the PipeWire native protocol. +Besides implementing nodes, they may control the graph. + +### Graph control + +The PipeWire server itself does not perform any management of the graph; +context-dependent behaviour such as monitoring for new ALSA devices, and configuring them so that they appear as nodes, or linking nodes is not done automatically. +It rather provides an API that allows spawning, linking and controlling these nodes. +This API is then relied upon by clients to control the graph structure, without having to worry about the graph execution process. + +A recommended pattern that is often used is a single client be a daemon that deals with the session and policy management. Two implementations are known as of today: + +- pipewire-media-session, which was the first implementation of a session manager.c + Today, it is used mainly in debugging scenarios. +- WirePlumber, which takes a modular approach: + It provides another, higher-level API compared to the PipeWire one, and runs Lua scripts that implement the management logic using the said API. + It ships with default scripts and configuration that handle linking policies as well as monitoring and automatic spawning of ALSA, bluez, libcamera and v4l2 devices. + The API is available for any process, not only from WirePlumber’s Lua scripts. + +### Node implementation + +With the nodes which they implement, clients can send multimedia data into the graph or obtain multimedia data from the graph. +A client can create multiple PipeWire nodes. +That allows one to create more complex applications; +a browser would for example be able to create a node per tab that requests the ability to play audio, letting the session manager handle the routing: +This allows the user to route different tab sources to different sinks. +Another example would be an application that requires many inputs. + +## API Semantics + +The current state of the PipeWire server and its capabilities, and the PipeWire graph are exposed towards clients -- including introspection tools like `pw-dump` -- as a collection of objects, each of which has a specific type. +These objects have associated parameters, and properties, methods, events, and permissions. + +Parameters of an object are data with a specific, well defined meaning, which can be modified and read-out in a controlled fashion through the PipeWire API. +They are used to configure the object at run-time. +Parameters are the key that allow WirePlumber to negotiate data formats and port configuration with nodes by providing information such as: + +- Multiple, supported sample rates +- Channel count +- Positions sample format +- Available monitor ports + +Properties of an object are additional data which have been attached on the behalf of modules and of which the PipeWire server has no native understanding. +Certain properties are, by convention, expected for specific object types. + +Each object type has a list of methods that it needs to implement. + +The session manager is responsible for defining the list of permissions each client has. Each permission entry is an object ID and four flags. The four flags are: + +- Read: the object can be seen and events can be received; +- Write: the object can be modified, usually through methods (which requires the execute flag) +- eXecute: methods can be called; +- Metadata: metadata can be set on the object. +- Link: any link can be made even to a port that is not visible by the owner of the port. + +### Object types + +The following are the known types and their most important, specialized parameters and methods: + +#### Core + +The core is the heart of the PipeWire server. +There can only be one core per server and it has the identifier zero. +It represents global properties of the server. + +#### Clients + +A client object is the representation of an open connection with a client process with the server. + +#### Modules + +Modules are dynamic libraries that are loaded at run time in the clients and in the server and do arbitrary things, such as creating devices or provide methods to create links, nodes, etc. + +Modules in PipeWire can only be loaded in their own process. A client, for example, can not load a module in the server. + +#### Nodes + +Nodes are the core data processing entities in PipeWire. +They may produce data (capture devices, signal generators, ...), consume data (playback devices, network endpoints, ...) or both (filters). +Notes have a method `process`, which eats up data from input ports and provides data for each output port. + +#### Ports + +Ports are the entry and exit point of data for a Node. +A port can either be used for input or output (but not both). +For nodes that work with audio, one type of configuration is whether they have `dsp` ports or a `passthrough` port. +In `dsp` mode, there is one port for channel of multichannel audio (so two ports for stereo audio, for example), and data is always in 32-bit floating point format. +In `passthrough` mode, there is one port for multichannel data in a format that is negotiated between ports. + +#### Links + +Data flows between nodes when there is a Link between their ports. +Links may be `"passive"` in which case the existence of the link does not automatically cause data to flow between those nodes (some link in the graph must be `"active"` for the graph to have data flow). + +#### Devices + +A device is a handle representing an underlying API, which is then used to create nodes or other devices. +Examples of devices are ALSA PCM cards or V4L2 devices. +A device has a profile, which allows one to configure them. + +#### Factories + +A factory is an object whose sole capability is to create other objects. +Once a factory is created, it can only emit the type of object it declared. +Those are most often delivered as a module: the module creates the factory and stays alive to keep it accessible for clients. + +### Common parameters and methods + +Every object implement at least the add_listener method, that allows any client to register event listeners. +Events are used through the PipeWire API to expose information about an object that might change over time (the state of a node for example). + +## Context + +The PipeWire server and PipeWire clients use the PipeWire API through their respective `pw_context`, the so called PipeWire context. +When a PipeWire context is created, it finds and parses a configuration file from the filesystem according to the rules of loading configuration files. + +*/ diff --git a/doc/dox/programs/index.md b/doc/dox/programs/index.md new file mode 100644 index 0000000..991ec72 --- /dev/null +++ b/doc/dox/programs/index.md @@ -0,0 +1,27 @@ +\page page_programs Programs + +Manual pages: + +- \subpage page_man_pipewire_1 +- \subpage page_man_pipewire-pulse_1 +- \subpage page_man_pw-cat_1 +- \subpage page_man_pw-cli_1 +- \subpage page_man_pw-config_1 +- \subpage page_man_pw-container_1 +- \subpage page_man_pw-dot_1 +- \subpage page_man_pw-dump_1 +- \subpage page_man_pw-jack_1 +- \subpage page_man_pw-link_1 +- \subpage page_man_pw-loopback_1 +- \subpage page_man_pw-metadata_1 +- \subpage page_man_pw-mididump_1 +- \subpage page_man_pw-mon_1 +- \subpage page_man_pw-profiler_1 +- \subpage page_man_pw-reserve_1 +- \subpage page_man_pw-top_1 +- \subpage page_man_pw-v4l2_1 +- \subpage page_man_spa-acp-tool_1 +- \subpage page_man_spa-inspect_1 +- \subpage page_man_spa-json-dump_1 +- \subpage page_man_spa-monitor_1 +- \subpage page_man_spa-resample_1 diff --git a/doc/dox/programs/pipewire-pulse.1.md b/doc/dox/programs/pipewire-pulse.1.md new file mode 100644 index 0000000..66d2ec8 --- /dev/null +++ b/doc/dox/programs/pipewire-pulse.1.md @@ -0,0 +1,58 @@ +\page page_man_pipewire-pulse_1 pipewire-pulse + +The PipeWire PulseAudio replacement + +# SYNOPSIS + +**pipewire-pulse** \[*options*\] + +# DESCRIPTION + +**pipewire-pulse** starts a PulseAudio-compatible daemon that integrates +with the PipeWire media server, by running a pipewire process through a +systemd service.

This makes it easier +to deal with. + +\code{.c} + if (spa_format_video_raw_parse(param, &data->format.info.raw) < 0) + return; + + printf("got video format:\n"); + printf(" format: %d (%s)\n", data->format.info.raw.format, + spa_debug_type_find_name(spa_type_video_format, + data->format.info.raw.format)); + printf(" size: %dx%d\n", data->format.info.raw.size.width, + data->format.info.raw.size.height); + printf(" framerate: %d/%d\n", data->format.info.raw.framerate.num, + data->format.info.raw.framerate.denom); + + /** prepare to render video of this size */ +} +\endcode + +In this example we dump the video size and parameters but in a real playback +or capture application you might want to set up the screen or encoder to +deal with the format. + +After negotiation, the process function is called for each new frame.

If gcc believes + the CFA is in %rsp, then unwinding may fail, because what's at the + CFA is not what gcc "expected" when it constructs the CFIs for the + places where the macros are instantiated. + + But we can't just add a CFI annotation to increase the CFA offset + by 128, to match the sub of 128 from %rsp, because we don't know + whether gcc has chosen %rsp as the CFA at that point, or whether it + has chosen some other register (eg, %rbp). In the latter case, + adding a CFI annotation to change the CFA offset is simply wrong. + + So the solution is to get hold of the CFA using + __builtin_dwarf_cfa(), put it in a known register, and add a + CFI annotation to say what the register is. We choose %rbp for + this (perhaps perversely), because: + + (1) %rbp is already subject to unwinding. If a new register was + chosen then the unwinder would have to unwind it in all stack + traces, which is expensive, and + + (2) %rbp is already subject to precise exception updates in the + JIT. If a new register was chosen, we'd have to have precise + exceptions for it too, which reduces performance of the + generated code. + + However .. one extra complication. We can't just whack the result + of __builtin_dwarf_cfa() into %rbp and then add %rbp to the + list of trashed registers at the end of the inline assembly + fragments; gcc won't allow %rbp to appear in that list. Hence + instead we need to stash %rbp in %r15 for the duration of the asm, + and say that %r15 is trashed instead. gcc seems happy to go with + that. + + Oh .. and this all needs to be conditionalised so that it is + unchanged from before this commit, when compiled with older gccs + that don't support __builtin_dwarf_cfa. Furthermore, since + this header file is freestanding, it has to be independent of + config.h, and so the following conditionalisation cannot depend on + configure time checks. + + Although it's not clear from + 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)', + this expression excludes Darwin. + .cfi directives in Darwin assembly appear to be completely + different and I haven't investigated how they work. + + For even more entertainment value, note we have to use the + completely undocumented __builtin_dwarf_cfa(), which appears to + really compute the CFA, whereas __builtin_frame_address(0) claims + to but actually doesn't.

This + happens automatically for the standard allocator functions such as + malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete, + delete[], etc. + + But if your program uses a custom allocator, this doesn't automatically + happen, and Valgrind will not do as well. For example, if you allocate + superblocks with mmap() and then allocates chunks of the superblocks, all + Valgrind's observations will be at the mmap() level and it won't know that + the chunks should be considered separate entities. In Memcheck's case, + that means you probably won't get heap block overrun detection (because + there won't be redzones marked as unaddressable) and you definitely won't + get any leak detection. + + The following client requests allow a custom allocator to be annotated so + that it can be handled accurately by Valgrind. + + VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated + by a malloc()-like function. For Memcheck (an illustrative case), this + does two things: + + - It records that the block has been allocated. This means any addresses + within the block mentioned in error messages will be + identified as belonging to the block. It also means that if the block + isn't freed it will be detected by the leak checker. + + - It marks the block as being addressable and undefined (if 'is_zeroed' is + not set), or addressable and defined (if 'is_zeroed' is set). This + controls how accesses to the block by the program are handled. + + 'addr' is the start of the usable block (ie. after any + redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator + can apply redzones -- these are blocks of padding at the start and end of + each block. Adding redzones is recommended as it makes it much more likely + Valgrind will spot block overruns. `is_zeroed' indicates if the memory is + zeroed (or filled with another predictable value), as is the case for + calloc(). + + VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a + heap block -- that will be used by the client program -- is allocated. + It's best to put it at the outermost level of the allocator if possible; + for example, if you have a function my_alloc() which calls + internal_alloc(), and the client request is put inside internal_alloc(), + stack traces relating to the heap block will contain entries for both + my_alloc() and internal_alloc(), which is probably not what you want. + + For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out + custom blocks from within a heap block, B, that has been allocated with + malloc/calloc/new/etc, then block B will be *ignored* during leak-checking + -- the custom blocks will take precedence. + + VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK. For + Memcheck, it does two things: + + - It records that the block has been deallocated. This assumes that the + block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - It marks the block as being unaddressable. + + VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a + heap block is deallocated. + + VALGRIND_RESIZEINPLACE_BLOCK informs a tool about reallocation. For + Memcheck, it does four things: + + - It records that the size of a block has been changed. This assumes that + the block was annotated as having been allocated via + VALGRIND_MALLOCLIKE_BLOCK. Otherwise, an error will be issued. + + - If the block shrunk, it marks the freed memory as being unaddressable. + + - If the block grew, it marks the new area as undefined and defines a red + zone past the end of the new block. + + - The V-bits of the overlap between the old and the new block are preserved. + + VALGRIND_RESIZEINPLACE_BLOCK should be put after allocation of the new block + and before deallocation of the old block. + + In many cases, these three client requests will not be enough to get your + allocator working well with Memcheck. More specifically, if your allocator + writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call + will be necessary to mark the memory as addressable just before the zeroing + occurs, otherwise you'll get a lot of invalid write errors. For example, + you'll need to do this if your allocator recycles freed blocks, but it + zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK). + Alternatively, if your allocator reuses freed blocks for allocator-internal + data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary. + + Really, what's happening is a blurring of the lines between the client + program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the + memory should be considered unaddressable to the client program, but the + allocator knows more than the rest of the client program and so may be able + to safely access it.

Normally, if an application uses a new + * feature in a library/API, it is unable to run on + * earlier versions of the library/API that do not + * support that feature. Such applications would either + * fail to launch or crash when an attempt to use the + * feature was made. This problem cane be solved using + * weakly-linked symbols. + * + * When a symbol in a framework is defined as weakly + * linked, the symbol does not have to be present at + * runtime for a process to continue running. The static + * linker identifies a weakly linked symbol as such in + * any code module that references the symbol. The + * dynamic linker uses this same information at runtime + * to determine whether a process can continue + * running. If a weakly linked symbol is not present in + * the framework, the code module can continue to run as + * long as it does not reference the symbol. However, if + * the symbol is present, the code can use it normally. + * + * (adapted from: http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html) + * + * A concrete example will help. Suppose that someone uses a version + * of a JACK client we'll call "Jill". Jill was linked against a version + * of JACK that contains a newer part of the API (say, jack_set_latency_callback()) + * and would like to use it if it is available. + * + * When Jill is run on a system that has a suitably "new" version of + * JACK, this function will be available entirely normally. But if Jill + * is run on a system with an old version of JACK, the function isn't + * available. + * + * With normal symbol linkage, this would create a startup error whenever + * someone tries to run Jill with the "old" version of JACK. However, functions + * added to JACK after version 0.116.2 are all declared to have "weak" linkage + * which means that their absence doesn't cause an error during program + * startup. Instead, Jill can test whether or not the symbol jack_set_latency_callback + * is null or not. If its null, it means that the JACK installed on this machine + * is too old to support this function. If it's not null, then Jill can use it + * just like any other function in the API. For example: + * + * \code + * if (jack_set_latency_callback) { + * jack_set_latency_callback (jill_client, jill_latency_callback, arg); + * } + * \endcode + * + * However, there are clients that may want to use this approach to parts of the + * the JACK API that predate 0.116.2. For example, they might want to see if even + * really old basic parts of the API like jack_client_open() exist at runtime. + * + * Such clients should include before any other JACK header. + * This will make the \b entire JACK API be subject to weak linkage, so that any + * and all functions can be checked for existence at runtime. It is important + * to understand that very few clients need to do this - if you use this + * feature you should have a clear reason to do so. + * + * + */ + +#ifdef __APPLE__ +#define WEAK_ATTRIBUTE weak_import +#else +#define WEAK_ATTRIBUTE __weak__ +#endif + +#ifndef JACK_OPTIONAL_WEAK_EXPORT +/* JACK_OPTIONAL_WEAK_EXPORT needs to be a macro which + expands into a compiler directive.

If so it is added to the list of mixer +; elements PA will control, keeping the order it read them in. If a +; mixer element described here has set the required= or +; required-absent= directives a path might not be accepted as valid +; and is ignored in its entirety (see below). However usually if a +; element listed here is missing this one element is ignored but not +; the entire path. +; +; When a device shall be muted/unmuted *all* elements listed in a path +; file with "switch = mute" will be toggled. +; +; When a device shall change its volume, PA will got through the list +; of all elements with "volume = merge" and set the volume on the +; first element. If that element does not support dB volumes, this is +; where the story ends. If it does support dB volumes, PA divides the +; requested volume by the volume that was set on this element, and +; then go on to the next element with "volume = merge" and then set +; that there, and so on. That way the first volume element in the +; path will be the one that does the 'biggest' part of the overall +; volume adjustment, with the remaining elements usually being set to +; some value next to 0dB. This logic makes sure we get the full range +; over all volume sliders and a very high granularity of volumes +; already in hardware. +; +; All switches and enumerations set to "select" are exposed via the +; "port" functionality of sinks/sources. Basically every possible +; switch setting and every possible enumeration setting will be +; combined and made into a "port".

This API (`The Linux Audio + Developer's Simple Plugin API') attempts to give programmers the + ability to write simple `plugin' audio processors in C/C++ and link + them dynamically (`plug') into a range of these packages (`hosts'). + It should be possible for any host and any plugin to communicate + completely through this interface. + + This API is deliberately short and simple. To achieve compatibility + with a range of promising Linux sound synthesis packages it + attempts to find the `greatest common divisor' in their logical + behaviour. Having said this, certain limiting decisions are + implicit, notably the use of a fixed type (LADSPA_Data) for all + data transfer and absence of a parameterised `initialisation' + phase. See below for the LADSPA_Data typedef. + + Plugins are expected to distinguish between control and audio + data. Plugins have `ports' that are inputs or outputs for audio or + control data and each plugin is `run' for a `block' corresponding + to a short time interval measured in samples. Audio data is + communicated using arrays of LADSPA_Data, allowing a block of audio + to be processed by the plugin in a single pass. Control data is + communicated using single LADSPA_Data values. Control data has a + single value at the start of a call to the `run()' or `run_adding()' + function, and may be considered to remain this value for its + duration. The plugin may assume that all its input and output ports + have been connected to the relevant data location (see the + `connect_port()' function below) before it is asked to run. + + Plugins will reside in shared object files suitable for dynamic + linking by dlopen() and family. The file will provide a number of + `plugin types' that can be used to instantiate actual plugins + (sometimes known as `plugin instances') that can be connected + together to perform tasks. + + This API contains very limited error-handling. */ + +/*****************************************************************************/ + +/* Fundamental data type passed in and out of plugin.

The access check + * is only performed once per client, subsequent checks return the same + * resolution. + * + * Permissions assigned to a client are configured as arguments to this + * module, see below. Permission management beyond unrestricted access + * is delegated to an external agent, usually the session manager. + * + * This module sets the \ref PW_KEY_ACCESS as follows: + * + * - If `access.legacy` module option is not enabled: + + * The value defined for the socket in `access.socket` module option, or + * `"default"` if no value is defined. + * + * - If `access.legacy` is enabled, the value is: + * + * - `"flatpak"`: if client is a Flatpak client + * - `"unrestricted"`: if \ref PW_KEY_CLIENT_ACCESS client property is set to `"allowed"` + * - Value of \ref PW_KEY_CLIENT_ACCESS client property, if set + * - `"unrestricted"`: otherwise + * + * If the resulting \ref PW_KEY_ACCESS value is `"unrestricted"`, this module + * will give the client all permissions to access all resources. Otherwise, the + * client will be forced to wait until an external actor, such as the session + * manager, updates the client permissions. + * + * For connections from applications running inside Flatpak, and not mediated by + * other clients (eg. portal or pipewire-pulse), the + * `pipewire.access.portal.app_id` property is to the Flatpak application ID, if + * found. In addition, `pipewire.sec.flatpak` is set to `true`. + * + * ## Module Name + * + * `libpipewire-module-access` + * + * ## Module Options + * + * Options specific to the behavior of this module + * + * - `access.socket = { "socket-name" = "access-value", ... }`: + * + * Socket-specific access permissions. Has the default value + * `{ "CORENAME-manager": "unrestricted" }` + * where `CORENAME` is the name of the PipeWire core, usually `pipewire-0`. + * + * - `access.legacy = true`: enable backward-compatible access mode. Cannot be + * enabled when using socket-based permissions. + * + * If `access.socket` is not specified, has the default value `true` + * otherwise `false`. + * + * \warning The legacy mode is deprecated.

The module creates + * virtual `echo-cancel-capture` source and `echo-cancel-playback` sink + * nodes and the associated streams. + * + * The echo-cancel module is mostly used in video or audio conference + * applications. When the other participants talk and the audio is going out to + * the speakers, the signal will be picked up again by the microphone and sent + * back to the other participants (along with your talking), resulting in an + * echo. This is annoying because the other participants will hear their own + * echo from you. + * + * Conceptually the echo-canceler is composed of 4 streams: + * + *\code{.unparsed} + * .--------. .---------. .--------. .----------. .-------. + * | mic | --> | capture | --> | | --> | source | --> | app | + * '--------' '---------' | echo | '----------' '-------' + * | cancel | + * .--------. .---------. | | .----------. .---------. + * | app | --> | sink | --> | | --> | playback | --> | speaker | + * '--------' '---------' '--------' '----------' '---------' + *\endcode + + * - A capture stream that captures audio from a microphone. + * - A Sink that takes the signal containing the data that should be canceled + * out from the capture stream. This is where the application (video conference + * application) send the audio to and it contains the signal from the other + * participants that are speaking and that needs to be cancelled out. + * - A playback stream that just passes the signal from the Sink to the speaker. + * This is so that you can hear the other participants. It is also the signal + * that gets picked up by the microphone and that eventually needs to be + * removed again. + * - A Source that exposes the echo-canceled data captured from the capture + * stream. The data from the sink stream and capture stream are correlated and + * the signal from the sink stream is removed from the capture stream data. + * This data then goes into the application (the conference application) and + * does not contain the echo from the other participants anymore. + * + * ## Module Name + * + * `libpipewire-module-echo-cancel` + * + * ## Module Options + * + * Options specific to the behavior of this module + * + * - `capture.props = {}`: properties to be passed to the capture stream + * - `source.props = {}`: properties to be passed to the source stream + * - `sink.props = {}`: properties to be passed to the sink stream + * - `playback.props = {}`: properties to be passed to the playback stream + * - `library.name = `: the echo cancellation library Currently supported: + * `aec/libspa-aec-webrtc`.
