[Feature Request] Support HTMLVideoElement.getVideoPlaybackQuality() for
MediaStream playback
rdar://172649550
https://bugs.webkit.org/show_bug.cgi?id=310007
Reviewed by Eric Carlson.
We implement MediaPlayerPrivateMediaStreamAVFObjC::videoPlaybackQualityMetrics
by implementing counter gathering in SampleBufferDisplayLayer.
Everytime we enqueue a sample in
LocalSampleBufferDisplayLayer::enqueueBufferInternal, we check the AVSBDL
metrics and call the SampleBufferDisplayLayerClient callback if metrics have
changed.
We send this information to WebProcess via IPC.
We limit video metrics sampling to every 0.25seconds for perf reasons.
Covered by added test.
