Small refactoring change to simplify the logic a tiny bit by removing one
unnecessary variable. No functional change intended.

This is a prerequisite step to making the `ResamplingAudioProcessor` public.

This method allows to call through to `StreamManager.focus()` of the currently playing SSAI stream.

Starting with Android 13 (API 33) an app needs to request the
permission to post notifications or notifications are suppressed.
This change documents this in the class level JavaDoc of the
`DownloadService`.

Issue: google/ExoPlayer#10884
PiperOrigin-RevId: 501346908

Starting with API 33 the POST_NOTIFICATION permission needs to be
requested at runtime or the notification is not shown.

Note that with an app with targetSdkVersion < 33
but on a device with API 33 the notification permission is automatically
requested when the app starts for the first time. If the user does not
grant the permission, requesting the permission at runtime result in
an empty array of grant results.

The migration strategy is to deprecate `androidx.media3.session.BitmapLoader` and copy the file into common since BitmapLoader is a public interface that apps could be relying on.

It makes more sense to have it in the AssetLoader now that decoding is
done there, particularly as the decoder factory should rarely be
customized.

Also remove the setter from the AssetLoader.Factory because it's
uncommon to have setters in a factory.

This improves performance and makes the code more intuitive.

It's unusual to have setters on a Factory.

For TV devices the skip button needs to have the focus to be accessible with
the remote control. This property makes this configurable while being set to
true by default.

The FrameProcessor is created on the GL thread, but:
- setInputFrameInfo() is currently called from the playback thread.
- release() is currently called from the transformer internal thread.

When audio processors are enabled during tunneling, they must produce
output immediately, ensuring that the timestamps of the output samples
correspond to the input and that no additional samples are produced.
This requirement is documented in the Javadoc of DefaultAudioSink.

However, this alone doesn't guarantee all buffers are immediately
written to the AudioTrack, because the AudioTrack writes are
non-blocking and may need multiple attempts.

When draining the audio sink at the end of the stream, we currently
fail in this situation because we assert that the timestamp must be
set (=the drain operation is a no-op). But this may not be true when
the previous non-blocking write wasn't fully handled. We can fix this
by saving the last timestamp and reusing it during draining.

There is no API to allow applications to use these currently. Until
that exists, these classes do not need to be public.

This makes more sense as SampleConsumer.dequeueInputBuffer returns the
same buffer as long as it is not queued.

Whether to write a sample or not was based on the timestamp of the
previous sample, rather than the current sample.

Split ExoPlayerAssetLoaderRenderer into audio and video renderers.

Initialising the fields as Integer and then getting a String on compute time is slow. Instead we directly initialise these fields as String. Improves the time taken in bundling PlayerInfo further to less than 200ms from ~300ms.

Also modified a test to improve productive coverage.

This brings together the multiple details about a muxer track, and
reduces the need for additional variables and more complicated track
tracking.

Throw a ParserException instead of a NullPointerException if the sample table (stbl) is missing a required sample description (stsd).

As per the javadoc for AtomParsers.parseTrack, ParserException should be "thrown if the trak atom can't be parsed."

Improves the time taken to construct playerInfo from its bundle from ~400 ms to ~300 ms.

Also made `Timeline.Window.toBundle(boolean excludeMediaItem)` public as it was required to assert a condition in tests.

PiperOrigin-RevId: 499512353

The old names are not really correct anymore because:
- The Audio/VideoTranscodingSamplePipelines do not decode anymore.
- The pipelines now mux the encoded data.

Whilst testing fallback functionality, I found that we were
aggressively reducing the resolution if it was not supported. A quick
test found that we could reduce by a much smaller increments.
Performance wise it appears these checks are incredibly quick.

The code for checking supported sizes was duplicated, with one case
having a bug because of this duplication (2/3 case). This CL abstracts
this into a loop.

Added another check in each of these tests to make sure we don't add keys to bundle for fields with default values.

Also fixed comments of similar changes in `AdPlaybackStateTest` and `MediaMetadataTest`.

Based on experimentation it seems that buffers can occasionally (roughly 1% of test runs) be dropped when rendering off-screen from EGL on the emulator. Specifically, in this test, sometimes after rendering three buffers with distinct timestamps only the first and third buffers' timestamps are handled in the `ImageReader`'s image available callback causing the assertion checking all frames rendered to fail. This behavior seems to be independent of the nanosecond presentation time attached to the buffers (as expected for off-screen rendering).

Introducing a pause of 1 second between rendering each frame reduces the flake rate to around 1/2000. This increases the run time of some of the tests, so this change also removes the 5 second `FRAME_PROCESSING_WAIT_MS` (it seems to be unnecessary when rendering off-screen) and instead uses a latch to wait until the frame processor has handled 'end of stream'.

- Do not fail silently if selectedEffects is null.
- Do not add an empty overlay effect to the Transformer to avoid
  transcoding video all the time.

- Improve AssetLoader Javadoc
- Fix Javadoc of sample pipelines
- Improve Javadoc of Transformer.startTransformation
- Move thread hops for Transformer listener callbacks to
  TransformerInternal

PiperOrigin-RevId: 499156604

When a listener method is deprecated, the new method should (by
default) called through to the deprecated one. This is because any
class that implements the method that is now deprecated needs to still
receive that callback.

It appears when onTransformationError(MediaItem, Exception) was
deprecated in favour of onTransformationError(MediaItem,
TransformationException), this deprecation was the wrong way round, and
the newer callback - onTransformationError(MediaItem,
TransformationResult, TransformationException) continued this mistake.

This CL now corrects this.
