This reverts commit e1223747c27e22c4c4c3006af10d58aec9718b28. Reason for revert: Breaks WebRTC roll into Chromium. E.g: https://ci.chromium.org/ui/p/chromium/builders/try/cast_shell_linux/1166014/overview Original change's description: > wayland: Add a common interface for screencast and remote desktop portal > > Change adapts the `base_capturer_pipewire` so that a portal can be > injected in the capturer. This allows the remoting to inject its > own portal for the purpose of capturing desktop stream as long > as the injected portal provides implementation of the new interface > that is added as part of this change. > > Additionally, a method has been exposed on the capturer to get > details about the portal session so that the remoting > implementation can use the same underlying session for controlling > inputs on the remote host. > > Finally, desktop capturer interface is extended with a generic > method `GetMetadata` that is used to retrieve session related > information by CRD and relay it over to its input injector. Clients > provide override for the method and it eventually invokes the > underlying `GetSessionDetails` method on the portal instance. > > Bug: chromium:1291247 > Change-Id: I81b7ce3b949d8be2e24e2d303d5fbc76a849209c > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/256400 > Reviewed-by: Alexander Cooper <alcooper@chromium.org> > Commit-Queue: Salman Malik <salmanmalik@google.com> > Cr-Commit-Position: refs/heads/main@{#36323} Bug: chromium:1291247 Change-Id: I73fbb1b9a103d61fd8d7f04bb8452b3e29da9025 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/256801 Bot-Commit: rubber-stamper@appspot.gserviceaccount.com <rubber-stamper@appspot.gserviceaccount.com> Owners-Override: Henrik Boström <hbos@webrtc.org> Commit-Queue: Henrik Boström <hbos@webrtc.org> Cr-Commit-Position: refs/heads/main@{#36331}
