Moves to a new setup where a decoder manages a single SourceMediaStream internally. Each stream returned from mozCaptureStream(UntilEnded) is a TrackUnionStream which is fed by the decoder's SourceMediaStream. We want the captured streams to be blocked while the media element is not playing. We do that by blocking any captured stream that has no SourceMediaStream feeding into it, and blocking any SourceMediaStream while its decoder is not playing. We arrange for the decoders's PlaybackEnded to be delayed until its SourceMediaStream has finished according to the media stream graph. This ensures the state of captured media streams corresponds more closely to the media element state. --HG-- extra : rebase_source : 3324ff0e9bdce9c71a23c0f5f2032815e9046081
