This renames the following (in alphabetical order, non-exhaustive):
AudioCaptureStream -> AudioCaptureTrack
AudioNodeStream -> AudioNodeTrack
AudioNodeExternalInputStream -> AudioNodeExternalInputTrack
DirectMediaStreamTrackListener -> DirectMediaTrackListener
MediaStream -> MediaTrack
- Note that there's also dom::MediaTrack. Namespaces differentiate them.
MediaStreamGraph -> MediaTrackGraph
MediaStreamTrackListener -> MediaTrackListener
MSG -> MTG (in comments)
ProcessedMediaStream -> ProcessedMediaTrack
SharedDummyStream -> SharedDummyTrack
SourceMediaStream -> SourceMediaTrack
StreamTime -> TrackTime
TrackUnionStream -> ForwardedInputTrack
- Because this no longer takes a union of anything, but only a single track
as input.
Other minor classes, members and comments have been updated to reflect these
name changes.
