This change - adds new type VideoTrackSourceConstraints expressing min/max FPS constraints. - adds new method VideoTrackSourceInterface::ProcessConstraints. - adds new method VideoSinkInterface<>::OnConstraintsChanged. - updates AdaptedVideoTrackSource and VideoBroadcaster to forward the constraints to sinks. - adds several unit tests for the added functionality. - and finally, implements OnConstraintsChanged in VideoStreamEncoder. Chromium will be updated in coming CLs to supply constraints set through the MediaStream module. go/rtc-0hz-present Bug: chromium:1255737 No-Try: true Change-Id: Iffef239217269c332a1aaa902ddeae2440929e22 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/235040 Commit-Queue: Markus Handell <handellm@webrtc.org> Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> Reviewed-by: Henrik Andreassson <henrika@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35197}
