670b091738 Bug 866434 - Part 2: Give each AudioParam that is connected to an AudioNode an AudioNodeStream; r=roc 
These MediaStreams are used as a way to down-mix the input AudioChunks, and
also as a way to get proper stream processing ordering.  The MediaStream for
the source AudioNode is an input to these streams, and these streams in turn
are inputs to the MediaStream that the AudioNode that owns the AudioParam owns.
This way, the Media Streams Graph processing code will order the streams so
that by the time that the MediaStream for a given node is processed, all of the
MediaStreams belonging to the AudioNode(s) feeding into the AudioParam have
been processed.

This has a tricky side-effect that those streams also being considered when
determining the input block for the AudioNodeStream belonging to the
AudioParam's owner AudioNode.  In order to fix that, we simply special case
those streams and make AudioNodeStream::ObtainInputBlock ignore them.

3490a03af3 Bug 850587. Part 2: Make NotifyHasCurrentData fire when a stream would be able to produce data if it was not blocked. r=jesup 
Also removes NotifyHasCurrentData's boolean parameter; we just fire this
once and treat a stream that has once had current data as always
having current data (since we block a stream that would advance
beyond its available data).

We had problems because we'd call Destroy on a port after calling Destroy on
its streams. This patch makes the port's Destroy ControlMessage not use a stream,
instead we get the stream from the port directly. It also makes us update the
graph's mPortCount only when the port is finally destroyed; this fixes a potential
bug where the current graph could shut down when all streams are removed, before
all ports have been completely destroyed.

15411af0fe Bug 779715. Part 4: Play all tracks of a media stream with multiple tracks. r=jesup 
Until now we've identified the "first active track" of a stream and played only that. Instead,
it makes more sense to play all the tracks.
For video, we pick the last track that has a video frame for the current time, and display that.

d3b9aab0ce Bug 779715. Part 1: Add basic support for ProcessedMediaStreams. r=jesup 
The main thing this patch does is to add ProcessedMediaStream objects and
MediaInputPorts connecting streams. ProcessedMediaStreams are an abstract
class that doesn't constrain what processing is actually performed, except
that for now we assume a stream's processing depends only on its inputs
window of data between mCurrentTime and mStateComputedTime.
This patch reorganizes the way the blocking status of each stream is computed.
The streams are partitioned into groups so that every stream which can affect
the blocking status of another stream is in the same group as that other stream.
We also add a pass to order the streams by dependency so we can process the streams
in order of dependency; this pass also identifies the streams that form part of a
cycle.

c069a47ae8 Bug 779721. Part 3: Don't clean up streams on the MediaGraph thread during a forced shutdown. r=jesup 
This is actually a better fix for bug 774597. We can rely on main thread code to call
Destroy on all the MediaStreams normally. These Destroy calls can be handled even when the
MediaGraph thread has been shut down, since MediaStreamGraphImpl::AppendMessage will
call RunDuringShutdown on the Destroy messages.

78f550e377 Bug 779721. Part 1: Simplify MediaStreamGraph's invariants around when messages are processed. r=jesup 
Rename mBlockingDecisionsMadeUntilTime to mStateComputedTime. The invariant is that
all graph state is known up to mStateComputedTime but not beyond it (except for some
stream contents that may be buffered beyond it).
Get rid of mMessageAffectedTime and all the code around computing "affected times" and "action times".
Instead, all messages take effect at mStateComputedTime.
Get rid of the two-phase execution of messages. Everything can just happen in a single Run() method.

5aa5e1864b Bug 750258. Advance mBlockingDecisionsMadeUntilTime to include time lost when the media graph control thread was stopped and all streams had underruns. r=jesup 
The first part just handles the case where nsAudioStream failed to allocate a stream. It won't be playing
anything, so instead of trying to get the audio position, just fall back to the media graph current time.
Otherwise GetPositionInFrames returns -1 and things go badly from there.
The second part simplifies the calculation of the next mCurrentTime to just make it based on real time.
We had some code to not let it advance past the end of a stream's buffer, but the next part will make that
unnecessary.
The third part is the real fix. When the new current time has advanced past mBlockingDecisionsMadeUntilTime,
that means the control loop didn't run in time to replenish the audio output buffers and keep up with its
other duties. Effectively all streams have been blocked between mBlockingDecisionsMadeUntilTime and
the new current time. Account for that by adding the difference as extra blocked time for every stream.
We only need to ensure that the stream is marked blocked from mBlockingDecisionsMadeUntilTime indefinitely
far into the future, and then update mBlockingDecisionsMadeUntilTime to the new current time, because the
code takes into account that only blocking decisions up to mBlockingDecisionsMadeUntilTime are valid.
