[Feature request] E-AC3 passthrough in Cast for ATV

Project Member Reported by tsunghung@chromium.org, May 20 2016 
Feature request: AC3/EAC3 passthrough in Cast receiver for Android TV.
That is, skip the decoding process and send the compressed (E)AC3 data to AudioTrack directly.
This feature is useful when a user connects a sound bar with (E)AC3 supported into an ATV. We can pass the raw (E)AC3 bitstream to the sound bar, and the sound bar will decode and render the audio.

We don't use AudioTrack anymore after Spitzer. To implement this you'll need to add a new AudioParameters stream type and refactor AudioBus containers to pass bitstream data instead of always deinterleaved float. You'll have to tell all the pieces from AudioRendererSink -> AudioOutputStream about your new stream type so they don't attempt to apply resampling, channel mixing, etc. You'll then need to write an OpenSLES output stream that can handle the E-AC3 data. You'll need to figure out how to check when this capability is available and how that might be reported to the renderer.

Comment 3 by tsunghung@chromium.org, May 20 2016 

Thank a lot for the heads-up, we will investigate how to add passthrough feature in Spitzer in our next release.
I have not studied Spitzer yet. Hopefully, we can create another AudioRendererSink implementation that goes to AudioTrack directly. Will discuss with you when we have better understanding of Spitzer architecture, thanks.

Add enumerations for compressed (E)AC3 sample format

This CL is part of enabling (E)AC3 passthrough feature. The new
enumerations indicate that the audio output is compressed (E)AC3
bitstream instead of PCM samples.

Use passthrough decoder for (E)AC3 formats

This CL is part of enabling (E)AC3 passthrough feature. Use "Android
raw decoder" for (E)AC3 audio formats. The decoder would only decrypt
but not decode the audio bitstream, i.e. the output would be clean but
compressed audio bitstream, not PCM.

Will create AudioTrack output stream to handle compressed bitstream
