From bug 1564451 comment 20 (android):

  1. Temporarily mute/unmute camera's video track(s) when app goes into/out of background, for parity with Chrome for Android. Test it here.

For #1 we need to expose a platform API to mute/unmute all camera tracks, since nothing does that yet AFAIK.

This enables a use case where MediaManager disables a MediaStreamTrack's input
track, and all listeners of NotifyEnabledStateChanged on the MediaStreamTrack's
main track will get notified.

There can be 1 input track for N MediaStreamTracks, so this simplifies how many
tracks will need to be tracked by MediaManager and explicitly disabled in the
graph.

Depends on D86072.

Before this patch, re-enabling a camera track would first render an old frame
(from when it got disabled), then when the camera has started anew, render the
new frames.

With the patch, the black frame from disabling remains until the camera has
started and is sending new frames.

Depends on D86925

Attachment #9169716 - Attachment is obsolete: true

Previously it listened for them on main thread, as notified by the
MediaStreamTrack it was transmitting directly. With this patch it
listens for them through the TrackListener in the graph, and will
get notified when any track prior to the MediaStreamTrack's main
track in the graph changes enabled state as well.

Depends on D86926.

This allows newly created window listeners, in MediaManager instances where the
cameras have already been muted, to get the right state.

Depends on D86931

This affects HTMLMediaElement and MediaRecorder, which are the only implementors
of NotifyEnabledStateChanged.

This use case is going to become more common as users will be able to globally
mute cameras before requesting one. While muted, the camera is off and no frames
will flow. The old logic for showing disabled video tracks as black relied on a
frame appearing that could be turned black.

With this patch in this case we will create a frame if none has been seen yet,
and it will have a hardcoded size.

Depends on D87127

r=karlt

This follows on the same logic ForwardedInputTrack is using.
