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.

/**
|
|
* Base class of AudioTrack and VideoTrack. The AudioTrack and VideoTrack
|
|
* objects represent specific tracks of a media resource. Each track has aspects
|
|
* of an identifier, category, label, and language, even if a track is removed
|
|
* from its corresponding track list, those aspects do not change.
|
|
*
|
|
* When fetching the media resource, an audio/video track is created if the
|
|
* media resource is found to have an audio/video track. When the UA has learned
|
|
* that an audio/video track has ended, this audio/video track will be removed
|
|
* from its corresponding track list.
|
|
*
|
|
* Although AudioTrack and VideoTrack are not EventTargets, TextTrack is, and
|
|
* TextTrack inherits from MediaTrack as well (or is going to).
