From ANSI-CTA-608-E R-2014 section 8.4:
> When closed captioning is used on line 21, field 2, it shall conform
> to all of the applicable specifications and recommended practices as
> defined for field 1 services with the following differences:
> 1. The non-printing character of the miscellaneous control-character
> pairs that fall in the range of 0x14, 0x20 to 0x14, 0x2F in field 1,
> shall be replaced with 0x15, 0x20 to 0x15, 0x2F when used in field
> 2.
> 2. The non-printing character of the miscellaneous control-character
> pairs that fall in the range of 0x1C, 0x20 to 0x1C, 0x2F in field
> 1, shall be replaced with 0x1D, 0x20 to 0x1D, 0x2F when used in
> field 2.
This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.
The `isMiscCode` method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.

This is a no-op, but it's more 'correct' because it avoids any potential

Although it can be useful to check the output format, it's not required or needed.
For some AudioProcessor implementations, it is stated/obvious that

Make it easier to support use of RGBA_101012 rather than RGBA_8888 for EGL

The reason for making the Muxer public is that we want to add an option

Currently, repeating the same item (via seekNext/Previous) implicitly
results in a seek to the default position of the current item, which
looks exactly the same as a direct seek. As a result, we don't send
onMediaItemTransition as we would for every other seekNext/Previous
call.
This can be fixed by explicitly marking the repeat case in the internal
BasePlayer/ExoPlayerImpl methods, so that the callback can be triggered.

- The naming DefaultMuxer is more consistent with the rest of
Transformer codebase (e.g. DefaultEncoderFactory).
- By hiding the implementation details of DefaultMuxer, the transition
to in-app Muxer will be seamless for apps using DefaultMuxer.
- The current plan is that DefaultMuxer will become the in-app muxer.

We already have logic to end all session except the current one if the
current one doesn't have a MediaPeriodId yet. This is assuming that this
only happens after a seek on the app side where the player doesn't have
detailled knowledge about the MediaPeriodIds yet.
Currently this logic isn't triggered if the window we are coming from
doesn't have its MediaPeriodId either as we run into another check that
keeps sessions around until we have a valid windowSequenceNumber.
Swapping both conditions fixes this case without breaking any of the
other known transition scenarios.

When debugging and fixing Issue: google/ExoPlayer#10666 I wanted to write a regression
test, but needed to add a test first... This is just a small bit of
coverage to start with. It checks the field/channel filtering works
correctly, but doesn't check any styling info. It also doesn't test
'pop on' subtitles (i.e. when the subtitle isn't shown until a 'end of
subtitle' signal is received).

If the sample type is Dolby Vision and the display does not support Dolby Vision, then the capabilities DecoderSupport flag is set to DECODER_SUPPORT_FALLBACK_MIMETYPE. This denotes that the renderer will use a decoder for a fallback mimetype if possible. This alters track selection as tracks with DecoderSupport DECODER_SUPPORT_PRIMARY are preferred.
UnitTests included
-DefaultTrackSelector test that checks track selection reordering with DECODER_SUPPORT_FALLBACK_MIMETYPE
-MediaCodecVideoRenderer test that checks setting of DecoderSupport flag based on Display's Dolby Vision support

Currently, a frame is dropped if it's requested release time is in the past.
This mode was added to support previewing. However, in normal ExoPlayer
playback, slightly late frames (<30ms late) are also rendered. On MediaCodec
side, this means calling `releaseOutputBuffer` with a release time in the
past.
PiperOrigin-RevId: 479615291
This mode is supported by using `C.TIME_UNSET` (which is a negative value). The
new logic decouples the value of `C.TIME_UNSET` and the frame dropping
behaviour.

* `MediaCodecRenderer` itself will be no-op for this method.
* `MediaCodecAudioRenderer` will propagate this value to its `audioSink`.
* Add logics in `DecoderAudioRenderer` to calculate `outputStreamOffsetUs`.

Currently `FrameProcessor.releaseOutputFrame()` method supports
Release at a specific system time
Drops the frame
This API is not that convenient to use when the caller wants to release a frame, now, regardless of the release time. A use case is to release (present) a frame when no frame is shown for a while, and it's thus better to just release the frame, now.
Currently if MCVR wants a frame to be rendered now, MCVR calls release frame with a set offset like 10us: `releaseOutputFrame(System.nanoTime() + 10_000)`. The 10us offset is to prevent the frame processor dropping the frame, due to thread hopping delays.
To make the API better usable, consider adding a mode for releasing the frame now, like (bold marks the new mode)
- Use C.TIME_UNSET to drop
- **Use -1 to release the frame immediately, or**
- Use an actual release time.

A follow up to stopping speaker playback with a Player decorator from
https://github.com/androidx/media/issues/15.
It looks like we will need to change to using playback suppression to avoid
errors like https://github.com/androidx/media/issues/167, when we don't start
a foreground service.
We may not have this implemented by 1.0, but would like it in the API and it seems to be appropriate.

* Before this CL, the texture was stored during the construction of the LUT processor. This failed since if one creates a list of GlEffects on the application thread, the texture will get stored in the application thread during the effect creation and not on the GL thread, which executes the FrameProcessors.

If the back buffer is using too much memory, there is a risk

The stream offset is used to calculate the presentation time of
a metadata object when reading and later when playing, to calculate
the current presentation time to decide whether to send the metadata
to the output.
Accordingly, the presentation time of a pending metadata that has been
calculated with a given offset needs to be recalculated when the
stream offset changes.
