+Subject: Bug 1819044 - fix build non-pipewire builds
+ r=webrtc-reviewers,pehrsons
+
+We should check only for PipeWire presence when building code specific
+to PipeWire.
+
+Differential Revision: https://phabricator.services.mozilla.com/D171071
+Mercurial Revision: https://hg.mozilla.org/mozilla-central/rev/7a879ad084a6e9768479c73cc5c3f4e9d95a2ab9
+
+Also includes:
+
+    Bug 1819044 - fix build non-pipewire builds (attempt #2) r=webrtc-reviewers,pehrsons
+
+    Make the new API available to everyone and just return an empty capturer
+    in case when building without PipeWire. It will not make any difference
+    because using X11 based capturers on Wayland is useless anyway so if we
+    fail for missing PipeWire on Wayland, it will have the same outcome.
