Before this change, the timestamps output from composition playback is offset
with the renderer offset. After this change, the offset is removed and the
timestamp behaviour converges with Transformer, that is, the timestamps of
video/images frames will follow that of the composition. For example, with a
composition of two 10-s items, clipping the first with 2s at the start, the
timestamp of the first frame in the second item, will be 8s.

When the frame release control invalidates a buffer and returns that
the buffer must be ignored, we need to exit early before performing
additional checks that may result in method calls using the invalid
buffer.

Usages removed in this CL are:
- onProcessedStreamChange, which was already called from the VideoSink
(via VideoFrameRenderControl)
- setOutputSurface, which was also already called from the VideoSink
- setFrameRate, which this CL now sets in the VideoSink
PiperOrigin-RevId: 640530903
Before this CL, we were checking whether the video sink was initialized
to determine whether it should be used. In the meantime,
shouldUseVideoSink has been introduced. Use this boolean to check
whether to use the video sink as it's a clearer signal.

This avoids having to add AnalyticsListener and catching the `onPlayerReleased` callback.
The `Exoplayer.release()` method is blocking and one can be sure that the player is released if the call returned. However, the method is useful for UI testing and asserting that the player is released after a certain UI action, e.g. closing the activity or detaching a window.

The CMCD data was incorrectly added to the `dataSpec` of the media segment instead of the init segment.
Also relaxed the condition for playbackRate to be C.RATE_UNSET when creating an instance of CmcdData.Factory as there was nothing enforcing this check.

When running in asynchronous mode, MediaCodec will be running the CPU to signal input and output buffers being made available for use by the player. With ExoPlayer.experimentalSetDynamicSchedulingEnabled set to true, ExoPlayer will wakeup to make rendering progress when MediaCodec raises these signals. In this way, ExoPlayer work will align more closely with CPU wake-cycles.

Currently ExoPlayer schedules its main work loop on a 10 ms interval. When renderers cannot make any more progress (ex: hardware buffers are fully written with audio data), ExoPlayer should be able to schedule the next work task further than 10ms out into the future.
Through `experimentalSetDynamicSchedulingEnabled` and these changes to `MediaCodecAudioRenderer`, ExoPlayer can use the data provided by the audio renderer to dynamically schedule its work tasks based on when it is expected that progress can be made.

If subtitle-parsing-during-extraction is enabled (now defaults to on),
the 'outer' extractor class name is often
`SubtitleTranscodingExtractor`, leading to some slightly useless error
messages like:
`None of the available extractors (FragmentedMp4Extractor, Mp4Extractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, TsExtractor, MatroskaExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, AviExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor, SubtitleTranscodingExtractor)`

If MediaCodec allocates passes an image buffer with a cropped region,
SurfaceTexture.getTransformMatrix will cut off 2 pixels from each dimensions.
The resulting videos will appear a little stretched.
This patch inspects the SurfaceTexture transform matrix, and guesses what the
unscaled transform matrix should be.

This case is most likely to happen when re-preparing a multi-period
live stream after an error. The live timeline can easily move on to
new periods in the meantime, creating this type of update.
The behavior before this change has two bugs:
- The player resolves the new start position to a subsequent period
that existed in the old timeline, or ends playback if that cannot
be found. The more useful behavior is to restart playback in the
same live item if it still exists.
- MaskingMediaSource creates a pending MaskingMediaPeriod using the
old timeline and then attempts to create the real period from the
updated source. This fails because MediaSource.createPeriod is
called with a periodUid that does no longer exist at this point.
We already have logic to not override the start position and need
to extend this to also not prepare the real source.

The two affected tests where playing until a specific
position to enable the player to read ahead. The method
pauses at exactly the target position, but then has
temporarily undetermined behavior because the playback
thread uses player.getClock().onThreadBlocked() that lets
the playback thread make progress in parallel to the test
thread. The tests were flaky because they sometimes made
so much progress that they ended playback before we could
query the updated renderer state.
This can be fixed by using
run(player).untilBackgroundThreadCondition instead, which
is guaranteed to be fully deterministic, but may not be able
to stop at exactly the desired position (which we don't
really need anyway for this test).

The method is only allowed to be called on prepared items.
This check was currently missing and also causing the
corresponding test to be flaky in ExoPlayerTest.

Before this change, if a playback error is thrown the test fails with a
timeout and no additional info:
```
java.util.concurrent.TimeoutException
at androidx.media3.exoplayer.e2etest.WebvttPlaybackTest.stallPlayerUntilCondition(WebvttPlaybackTest.java:361)
```
After this change, the test failure includes a much more useful stack
trace, e.g. from 0352db9a37:
```
Caused by: java.lang.IllegalStateException: Legacy decoding is disabled, can't handle text/vtt samples (expected application/x-media3-cues).

To override this change, and go back to parsing during rendering,
apps must make two method calls:
1. `MediaSource.Factory.experimentalParseSubtitlesDuringExtraction(false)`
2. `TextRenderer.experimentalSetLegacyDecodingEnabled(true)`

The test currently resets the time too far in the past and then has
to run through ~30000 additional iterations of doSomeWork to reach
the end, sometimes triggering the test timeout.
Fix it by resetting the time to the intended start position when
transitioning items.

This means the content source is 'prepared' instantly with a
placeholder, enabling all further preparation steps (e.g. loading
preroll ads) while the actual content is still preparing. This
improvement can speed up the start time for prerolls in manifest-based
content that doesn't have a zero-time preparation step like progressive
media.

This allows apps to better detect when the platform
reclaims a codec. This requires adding the error code
to MediaCodecDecoderException.

The class currently tracks the input format itself, updating it too
early in onConfigure() instead of onFlush(). This causes issues when
the format changes and the new values are applied to the silence
skipping logic of the old format. The fix is to use the base class
input format handling instead.
Issue: androidx/media#1352

Due to loading a MediaSourceFactory via reflection:
Before this change
* the content type was logged as an integer, rather than a human-readable string
* `ClassNotFoundException` was swallowed silently by `maybeLoadSupplier` without telling the user what module they were missing
After:
* ClassNotFoundException is swallowed silently ONLY when determining supported types
* ClassNotFoundException is bubbled up when we are trying to play media without the corresponding module properly loaded
PiperOrigin-RevId: 632568989
The same doSomeWork iteration that triggers the silence skipping
discontinuity may already have another discontinuities (like
AUTO_TRANSITION), which should take precedence over the silence
skipping.

When the period has loaded to the end of the source, the `period.getBufferedPositionUs` will be set to `C.TIME_END_OF_SOURCE`, which is a negative value. Thus, the original `continueLoadingPredicate` will never turn to `false`, as the `bufferedPositionUs` is definitely less than the target preload position that is expected to be positive.
In this change, we added `PreloadMediaSource.PreloadControl.onLoadedToTheEndOfSource(PreloadMediaSource)` to indicate that the source has loaded to the end. This allows the `DefaultPreloadManager` and the custom `PreloadMediaSource.PreloadControl` implementations to preload the next source or take other actions.
This bug was not revealed by the the `DefaultPreloadManagerTest` because the related tests were all using the `FakeMediaSource` and only setting the preload target to `STAGE_TIMELINE_REFRESHED`. Thus, the tests for testing the `invalidate()` behaviors were modified to use the real progressive media whenever possible, unless we have to use `FakeMediaSource` to squeeze a chance to do more operations between the preloading of sources to test some special scenarios.

For offloaded playback, reset the tracking field for stream completion in `DefaultAudioSink` prior to calling `AudioTrack.stop()` so that `AudioTrack.StreamEventCallback#onPresentationEnded` correctly identifies when all pending data has been played.

When the PlaybackParameters are set to their DEFAULT value, we
currently bypass the audio processor chain when determining the
output media position, under the assumption that no timestamp
change happens in the audio processors. This assumption may not
be true as the audio processors can change playout durations on
their own accord independent of the provided PlaybackParameters.
To correctly reflect any updated playout duration, we can just
always check the audio processor chain. The default implementation
will continue to assume that only the SonicAudioProcessor changes
the playout duration.
