In `MediaPipelineTransmit::SetTrack()` when a track of different MTG is replaced, the transmission is stopped and restarted asynchronously. This can create a problem if a new stop has arrived in the meantime. The transmission should not be restarted in that case.
This change adds a boolean, to check when an asynchronous start is expected and ignores it if not needed.

waiting until StartIceChecks is called, it is less likely that we will end up

Before this patch, if a send audio MediaStreamTrack ended, we ended up not
sending anything over the network. If replaceTrack() at that point replaced the
ended track with a live one, we'd start sending data again, but the rtp stream
would continue from where the previous track ended.
Having a gap in audio like that would confuse a receiver's *video* jitter
buffer, because it's trying to sync to an audio track that just had a massive
amount of "jitter" (it can't tell the difference).
This patch fixes this by adding a track layer in MediaPipelineTransmit that
remains active for as long as the MediaPipeline is active. Thus if the send
audio MediaStreamTrack ends, we continue sending silence over the network, which
the receiver can understand. If later replaced, the receiver sees real audio
instead of silence and continues gracefully.

This swaps things around so that received tracks in peer connections have a
content principal instead of a null principal initially.
This puts an extra requirement on us to not output any frames under the content
principal after ALPN has been negotiated with requested privacy, but before this
private principal has been signaled to the MediaPipelines. The private principal
is signaled from the STS thread, via the main thread, whereas media is consumed
directly by MediaPipelines after being received on the STS thread.
This patch adds an extra signaling path directly from the STS thread that tells
MediaPipelines to make their PrincipalHandle private, and to ignore any data
until the private PrincipalHandle is set. It also moves the responsibility of
updating the principal of the received MediaStreamTracks from TransceiverImpl
to MediaPipeline, so it's all in the same path.
This lets all MediaStream and MediaStreamTrack APIs consume received tracks
directly after getting exposed to JS without errors. In case privacy is later
requested, consumers that have already been set up must handle this on the fly.

This change mainly removes the `mTracks` member from MediaStream and moves all
associated members up a level, so that a MediaStream in practice represents a
single track.
Classes will be renamed in a future patch to reflect this.
Other changes include:
The new `mEnded` member of MediaStream changes meaning to only become true when
all data in the stream has been processed. It stems from
StreamTracks::Track::mEnded which used to become true as soon as the last bit of
data had been added to a track, and there could still be data in the track that
would get processed in future iterations. We are moving towards not having any
future data in tracks, which is why this change is ok to make -- keeping the old
behavior will soon not make sense.
TrackUnionStream is changed to no longer take a list of streams as input and
forward the union of their tracks to itself. Instead it's limited to having one
track as input at a time.
The autofinishing functionality that TrackUnionStream had before has been
transformed into an autoending functionality to allow it to defer ending until
its been told that it's ok to end through the control API. This lets a single
TrackUnionStream span the lifetime of multiple inputs, which will be useful for
making DecodedStream spec compliant with HTMLMediaElement::CaptureStream(), and
for implementing the currently discussed MediaRecorder::ReplaceTrack(), to name
a few potential use cases.
AudioNodeStreams used to only have a track (and thus an AudioSegment) if the
EXTERNAL_OUTPUT flag was enabled on them. With all MediaStreams now representing
a track, AudioNodeStreams inherently have an AudioSegment as a member. It is
however only used with data if the EXTERNAL_OUTPUT flag is enabled.

This adds a reference counted implementation of Telemetry::AutoTimer for use
in timing WebRTC calls. The telemetry is recorded when the reference count goes
from one to zero. This allows capturing the total call duration, rather than
the duration of individual PeerConnections. The timers are stored in a
HashTable, indexed by the Document URI, allowing for call durations to be
calculated individually for separate pages.
This reuses the existing WEBRTC_CALL_DURATION telemetry key. This means we
won't be able to compare telemetry from versions of Firefox with this change
to versions of Firefox without this change. The reason for making this change
is that the telemetry is not very useful in its current form, so I think it
makes sense to do this rather than adding a new key.

The Telemetry::AccumulateTimeDelta function reports in milliseconds but I had
assumed seconds when I added the hostname obfuscation ICE duration histogram.
This change adjusts the "high" value accordingly.
With the telemetry we've collected to date, 60% of the values are below 600
milliseconds, so I think that setting a high value of 30 seconds should be
sufficient even if there is a long tail. Since this does not change the data
being collected, no additional data-review is required, but it does require
renaming the key.

Freeing the conduits when the transceiver is stopped releases all of the
associated webrtc.org objects which results in substantial memory savings.
On my system, with an opt+debug build and 200 stopped transceivers, I see
373.17 MB of memory use in the content process without this patch, and
158.93 MB of memory use with this patch applied.
Going further and calling Shutdown_m as part of Stop() reduces the memory
use to 157.98 MB, which seems like a marginal improvement at the cost of
a much larger risk of introducing bugs.

In OnIncomingFrame() we check if the capture has started by calling
CaptureStarted() which holds a lock. If StopCapture() is called on the
control thread after we check CaptureStarted() it is possible that
_captureCapability will be zeroed out prior to frame being delivered because
the lock has been released. This would result in an unknown video type in
CalcBufferSize() and trigger an assertion there. This creates a local copy of
_captureCapability with the lock held to ensure it is not zeroed out when the

In order to encode video frame, we have to convert `webrtc::VideoFrame` to gecko's video data, and then send this YUV-based video data to the encoder.
The encoder won't return an encoded frame everytime when we call its `encode()`, so we have to wait until there are valid samples added to `mEncodedFrames`.
Then, convert the `MediaRawData` to `webrtc::EncodedImage` and provide an NAL entries list to indicate where the NALs are in the encoded bytes stream and how large they are. We would send those data back
to the consumer of the encoder via calling a callback function `OnEncodedImage()`.

This is inherently large, because modifying these bits of DOMMediaStream and
MediaStreamTrack affects all consumers and producers of all DOMMediaStreams and
MediaStreamTracks.
Things are generally much simpler now.
Producers of tracks now create a MediaStream in the graph, add it to a
MediaStreamTrackSource subclass that takes ownership of it, and add the source
to a MediaStreamTrack. Should the producer need a DOMMediaStream it is now much
simpler to create as the only thing needed is the current window. The stream is
a rather simple wrapper around an array of MediaStreamTracks.
HTMLMediaElement is still not as straight forward as other consumers since it
consumes the DOMMediaStream directly, as opposed to a set of tracks.
The new MediaStreamRenderer helper class helps bridge the gap between this fact
and the new track-based MediaStreamGraph interface, as it needs to juggle
registering multiple audio tracks for audio output. This hooks into existing
HTMLMediaElement logic and brings a welcome simplification to all the glue
previously needed there.

Because IPC call runs asynchronously in both remote decoder process and

scheduled to run after the flush promise is resolved, and Codec.queueInput()

To help check the validness of buffers, a session ID increased by flush
is added to both RemoteDataDecoder and remote codec service and will be
passed through IPC. If the passed ID doesn't agree with current session
ID, it means the buffer doesn't belong to current session and should be
discard.

This must have been broken while addressing review comments in Bug 1548841,
the first commit has it right and the last commit in the series breaks it.
Since we don't yet generate mDNS addresses in Firefox, the unit tests would not
catch this problem, and interoperability with other browsers would continue to
work due to peer reflex candidates.
We will have test coverage for this once we land generating our own mDNS
candidates. ICE will fail in the mochitests if we don't support resolving
mDNS addresses properly, which is how I discovered this bug.

In bug 1538508 we changed the MediaChangeMonitor to raise an error when we try
to create a decoder and we don't yet have the H.264 extra data, to maintain the
assumptions made by OpenH264/WebRTC. This however doesn't play nice with the
HLS demuxer, which won't always give you extra data after a seek.
So change the MediaChangeMonitor to by default assume that it should just drop
frames until it has the extra data it needs to create a decoder. We can flag
this mode off in the WebRTC MediaDataDecoder.
