When operating the MediaCodec in asynchronous mode, we are seeing
NPEs raised from the DefaultAudioSink because output buffers are pushed
to the DefaultAudioSink with the DefaultAudioSink not configured yet.
This is possible to happen if an output buffer is passed with
MediaCodecAudioRenderer.processOutputBuffer() before an output format
change.
One possible code path to trigger this is when an output format change
is pending and we flush MediaCodec (e.g. for a seek): the callback is
waiting in the looper's queue but we ignore all currently queued
callbacks after a flush().
This commit checks for a pending output format change during a flush():
if one exists, and the next MediaCodec output callback right after the
flush() is an output buffer (and not a new output format), then the
pending output format is propagated first.
The only adapter that needs to change is the
AsynchronousMediaCodecAdapter which previsouly deleted all pending
callbacks immediately on flush(). The AsynchronousMediaCodecAdapter now
needs to also handle every enqueued callback in order to identify is
there's a pending output format change.
Testing: added unit tests for the new code. I have verified that if we
pass an output buffer to the audio renderer before the output format, it
will result on the specific NPE, but I cannot reproduce the base
scenario (an output format change is pending when flushing) on a real
device because we can't know if an output format is indeed pending.

We currently propagate only ColorInfo, but propagating the whole Format
is generally useful (e.g., to get the frame-rate on the output side of
the decoder).
PiperOrigin-RevId: 310359650
This allows properties to propagate when switching view types
(e.g. bottomPaddingFraction).
It also allows the style-stripping code to be pushed up to SubtitleView
and therefore shared.

Fixes AsynchronousMediaCodecBufferEnqueuerTest broken tests by
enqueueing input buffers that have previously been dequeued from the
MediaCodec.
The test assumes that the shadow MediaCodec implementation can dequeue
at least 10 input buffers before queueing them back. Although fragile,
it seems to work with the current robolectric shadow MediaCodec. This is
at the moment preferred compared to making the test more complicated.

Currently, DashMediaPeriod only takes into account as CEA-608 accessibility tags as embedded
closed captions tracks CEA-608. CEA-708 closed captions format is parsed when is present on
its own AdaptationSet, but not when is embedded as an accessibility tag in a video AdaptaticonSet.
Embedded CEA-708 support is added by parsing accessibility tags like the example below:
<Accessibility schemeIdUri="urn:scte:dash:cc:cea-708:2015" value="1=lang:eng;2=lang:deu"/>
<Accessibility schemeIdUri="urn:scte:dash:cc:cea-708:2015" value="1=lang:eng;2=lang:eng,war:1,er:1"/>
so it creates a new CEA-708 track for accessibility tags with schemeIdUri = urn:scte:dash:cc:cea-708:2015
and extract accessibilityChannel and language from value attribute.

The PlaybackStateCompat#STATE_BUFFERING expects the playback to begin
once enough data has been buffered. This is however not the case if
playWhenReady is not set on the exoplayer.
Some part of the audio pipeline in the DefaultAudioSink
(PCM processors) are expecting little endian buffers.
As a result, in order to behave like MediaCodec,
make sure the passthrough MediaCodec-bypass pipeline
also processes little endian output buffers.

This aligns mkv with mp4, flv and ts extractors.
This issue was found when AAC in an MKV container was not offloaded
as format.codecs was null.

Previously the input format values were used,
but it could be incorrect if two format change were
occurring in quick successions.

These methods operate on a thread-safe collection and are thus
inherently thread-safe. This simplifies some player setup configurations
where initial listeners are added on a background thread (e.g. when
using a dependency injection framework).

Users of addTextOutput should instead query the current cues if they
need them. This is more consistent with how other listeners are handled.

We currently have DecoderVideoRenderer and VideoDecoderRenderer, which
is very confusing! This one is package private, so we can rename it to
remove some of the confusion.
Also fix some nullness issues.

In passthrough MediaCodec is not used except if
the format has a DRM.
Nevertheless the code was still requiring that a
passthrough decoder be present even if it was not going to be
used (aka no drm).
PiperOrigin-RevId: 309947271
- Fix DecoderAudioRenderer to re-init codec if the DRM session changes.
- Add canKeepCodec to DecoderVideoRenderer. Previously it was assumed
that the decoder could be re-used, but this will not be true in all
cases for FfmpegVideoRenderer.

If the condition isn't fulfilled, they currently block until the
test runner times out the test. Our usual approach is to timeout
in the test itself so that the error message is clearly showing the
blocked condition.
Also clean-up some documentation.

Now that MediaCodec is not use in passthrough, no
MediaCodec should be created in this mode.
Additionally, do not instantiate a MediaCodec in passthrough

These tests require longer content so that the ads are spaced apart far enough
to trigger preloading while content is playing (rather than immediately as soon
as a position is reported).

With sample prepare (non-chunkless) the `Format` object in the TrackGroup is derived from the data in the stream and data in the manifest. This change includes the roleFlags from the HLS manifest parse in the final derived format.
