This mode allows the extractor to support streams with multiple
programs declared in the PAT, but only one PMT. This is necessary
to support tuner-obtained media.

textWidth can be negative if textLeft extends parentRight (i.e.
the subtitle is positioned entirely off the screen to the RHS).
We should just discard and log a warning in this case.

Implement VP9 profile 2 - 10 bit BT2020 support with libvpx. This code truncates the 10 bits to 8. We'll later update this to upload half-float or 16 bit short textures.

Pending: Convert BT2020 to DCI-P3 before render.

I'll add the same code to V2 after initial review.

This change exposes declared CEA-608 and EMSG tracks. The

I'm going to introduce an EmptySampleStream that will be used in
some cases in conjunction as part of 608/EMSG support. This change
avoids EmptySampleStream having to provide a dummy format.

At the end of playback, BufferProcessors need to be drained to process all
remaining data, then the output needs to be written to the AudioTrack before
stop() is called.

Clarify naming for ClearKey DRM support

Added support for CENC ClearKey

This allows the TsExtractor to automatically determine the
closed caption tracks to expose by parsing available
descriptors.

This allows BufferProcessors to partially and/or asynchronously handle
input/output. Document contract for queueInput and getOutput.

Update ResamplingBufferProcessor to use the new interface.

Separate submitting bytes vs. writing data to the AudioTrack.

This CL allows passing multiple formats describing CC channels to the
TS payload reader factory. As a simple usecase, ATSC can expose both
608 channels by passing a two element list with the corresponding
accessibility channels. The HLS media source can construct this list
from the EXT-X-MEDIA:TYPE="CLOSED-CAPTIONS" tags, including language
and selection flags. The interface extends without modification to
708.

Pending work:
* Multiple CC channels in HLS.
* caption_service_descriptor parsing for overriding the user's selection.
* 708 support in SEI reader.

supported by the device.
