This reverts commit dd20c9c1e3f681f6c33d1879c76f588bd4b095bd. Reason for revert: Speculative revert; looks like it causes crashes on official builders. See crbug.com/901319. Original change's description: > Add support for screen sharing with PipeWire on Wayland > > Currently, when users want to use the screen sharing and are using the > Wayland display server (the default on Fedora distribution), then it > doesn't work, because the WebRTC only includes the X11 implementation. > This change adds the support by using the PipeWire multimedia server. > > The PipeWire implementation in WebRTC stays in > screen-capturer-pipewire.c and is guarded by the rtc_use_pipewire build > flag that is automatically enabled on Linux. > > More information are included in the relevant commit messages. > > Tested on the current Chromium master and Firefox. > > The sysroot changes are requested in: > https://chromium-review.googlesource.com/c/chromium/src/+/1258174 > > Co-authored-by: Jan Grulich <grulja@gmail.com> > Co-authored-by: Eike Rathke <erathke@redhat.com> > Change-Id: I212074a4bc437b99a77bf383266026c5bfae7c4a > > BUG=chromium:682122 > > Change-Id: I212074a4bc437b99a77bf383266026c5bfae7c4a > Reviewed-on: https://webrtc-review.googlesource.com/c/103504 > Commit-Queue: Patrik Höglund <phoglund@webrtc.org> > Reviewed-by: Patrik Höglund <phoglund@webrtc.org> > Reviewed-by: Brave Yao <braveyao@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#25461} TBR=phoglund@webrtc.org,jamiewalch@chromium.org,niklas.enbom@webrtc.org,braveyao@webrtc.org,tomas.popela@gmail.com # Not skipping CQ checks because original CL landed > 1 day ago.
