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.

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

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.

This change allows an overlay to be sized with respect to the video dimensions.

Events on the wrapper should be propagated to TransformerInternal as
soon as they occur, switching round the process so TransformerInternal
does not have to query MuxerWrapper.

This CL is a prerequisite for the child CL, where MuxerWrapper can
simplify the internal state and logic.

We might as well keep this enabled by default, rather than having to
manually toggle it on to investigate RTL issues like Issue: androidx/media#227.

Before, it was possible for onDurationUs() and onAllTracksRegistered()
to be called before onTrackAdded() because they are called from
different threads. onDurationUs() and onAllTracksRegistered() are called
from the Transformer internal thread, and onTrackAdded() is called from
the playback thread.

This is useful if an app passes a custom AssetLoader that can only
output encoded or decoded samples.

Did not do this optimisation for `AdPlaybackState.AdGroup` as its length is zero for `AdPlaybackState` with no ads.

No need to pass default values while fetching keys, which we always set in `AdPlaybackState.AdGroup.toBundle()`.

Added another check in test to make sure we don't add keys to bundle for fields with `null` values.

AssetLoader declares the tracks with a setTrackCount() method. Setting
the track count on the MuxerWrapper is easier than calling
registerTrack() as many times as the number of tracks.

AssetLoader declares the tracks with a setTrackCount() method. Setting
the track count on the FallbackListener is easier than calling
registerTrack() as many times as the number of tracks.

PiperOrigin-RevId: 496919969

The TransformationRequest passed to FallbackListener (and
createSupportedTransformationRequest) can have null for values that
are inferred from source. Within fallback, this can be height, width,
video mime type and audio mime type (HDR mode is not linked to source).
requestedFormat has these values populated from source, and
supportedFormat then finds the closest supported values to the
requested.

If any of the values in supportedFormat do not match the
requestedFormat, then this method would build upon the
TransformationRequest and update ALL possible fallback fields. This is
a problem because the fallback listener compares the original request
to the fallback one and notifies about all the fields that have
changed.

This CL changes this so that only the values that are not the same as
requested are changed in the supported request that is given to the
fallback listener.
