Subject: Bug 1914835 - With ScreenCaptureKit embed the mouse cursor directly.
|
|
r=webrtc-reviewers,ng
|
|
|
|
The MouseCursorMonitor on macOS is rather expensive, as for every pulled frame
|
|
it compares all pixels of the cursors used for the current and last frames.
|
|
Getting to the pixels may also incur a conversion.
|
|
|
|
Note that this comparison happens even if the backend reports it had embedded
|
|
the cursor already, as the embedding only affects composing the monitored cursor
|
|
into a captured frame.
