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}
