- Tunneling can be enabled by calling:
trackSelector.setTunnelingAudioSessionId(
C.generateAudioSessionIdV21(this));
- If enabled, tunneling is automatically used when the renderers
and track selection combination support it. Tunneling is
automatically turned on and off through playlists if the support
changes.
Issue: #1688
under certain circumstances (e.g. seek to a position where the input format
changed) the audio track needs a reconfigure even if there aren't any
pending buffers
This class can accommodate extra information that may potentially
be specified by TrackSelectors in the future (e.g. configuration
for renderers). Even if we don't do this, it's cleaner to have a
proper class and an info field to refer to, as opposed to using a
Pair.

Also revert ability to query for a decoder that explicitly
supports tunneling, since in the new design we'll just be
querying the first decoder provided by the MediaCodecSelector
and then reporting what it supports. This is in line with
what we do when reporting support for adaptive switching.

Move initialization code from the audio renderers into handleBuffer. The audio
session id and tunneling enabled state can be altered using new setters.
This change is not intended to change the behavior of the audio renderers.
Before this change, the AudioTrack would always be reinitialized by the
renderers before calling handleBuffer.
Add a protected onAudioTrackUnderrun method for custom renderers that want to
implement custom handling of underruns.

These currently lead to cryptic ArrayIndexOutOfBoundsExceptions being thrown from System.arraycopy() so my proposal is to throw a more useful ParserException instead.

It's a nicer place for it to live once it starts being passed
around more widely (e.g. through the video renderer, for
tunneling)

Although the underlying platform AudioTrack is capable of
writing the AV sync header from M onward, I've opted not
to use the functionality since it appears to allocate an
unnecessary (and large) number of ByteBuffers. We can swap
over from O if this is addressed.

This is implemented in the same way as in MediaCodecRenderer.
Move codec != null guard into feedInputBuffer to handle the case of an input
format change with no dequeued buffers where the codec can't be reinitialized
immediately.

- Use a single constant for unset/unknown times across
all time bases. Note also that this moves away from
use of -1 for unset/unknown times in ms, which was a
bad choice (it might conflict with real times, such
as a time representing being just behind the start
of a live window).
- Add a few other unset constants, and use them.
- Fix some hardcoding of -1 where existing constants
should have been used.

In V1 we received complaints that Renderer was too locked down.
In particular, it wasn't possible to implement a Renderer that
wrapped another Renderer, since most of the methods were package
private and final (e.g. enable).
This change defines Renderer as a proper interface, removing
this limitation. A method-reordering-only change will follow
this one, to get things into a nice consistent/sane order in
each of the Renderer classes.

1. Rename "extensions" package to "decoder". It's used by both
text and (should be used by) metadata, so it's no longer just
for extensions.
2. Move Buffer objects move into the decoder package.
3. Rename SubtitleParser and MetadataParser to SubtitleDecoder
and MetadataDecoder respectively, since they extend Decoder.
Ditto for all subclasses.
4. Subtitle and Metadata decoders now throw their own exception
types rather than ParserException.
5. Move MediaCodec classes into a mediacodec package, with the
exception of the concrete audio and video renderers.
6. Create an audio package to hold the two audio renderer classes
plus related util classes.
7. Create a video package to hold the one video renderer class
plus related util classes.
After this change the following nice properties hold:
1. Want a video renderer? Look in the video package. Ditto for
audio, text and metadata.
2. All TrackRenderer implementations use a decoder of some kind
to decode buffers received from the source, so we have
consistent terminology there.

- The package is renamed to avoid conflicts with v1, should any
app wish to include both v1 and v2 for a period of time. This is
similar to the approach used by some other open source projects
(e.g. okhttp).
- Copyright year is updated everywhere for completeness.
