When bundling PlayerInfo, we remove data when the controller is not
allowed to access this data via getters. We also remove data for
performance reasons. In the toBundle() method, it's currently hard to
make the connection between allowed commands and filtering, because
the values are checked at a different place. This can be made more
readable by forwarding the applicable Commands directly.

The only functional fix is to filter the Timeline when sending the
first PlayerInfo after a connecting a controller if the command to
get the Timeline is not available. This also allows us to remove a
path to filter MediaItems from Timelines as it isn't used.

If a device only supports 1920x1080 as maximum resolution, then adding
the 25% case ensures 8k is reduced correctly.

This is an AssetLoader that wraps a sequence of AssetLoaders. It will
be used for constrained multi-asset.

This class can currently only concatenate media items with the exact
same format.

PiperOrigin-RevId: 502525796

Also remove usages of TransformationRequest convenience methods
(setScale, setRotationDegrees and setResolution).

Some usages of setResolution can't be removed yet because they are used
for fallback.

This CL includes following changes:
1. Remove GCA related terms/links from java docs and comments.
2. Make class final where ever possible.
3. Append /* package */ for default classes.
4. Change java docs to recommended format.
5. Replace term "packet" with "sample" to avoid confusion.
6. Correct TODO format.
7. Delete MediaFormatUtil.java from muxer module and add its methods into MediaFormatUtil.java in common module.

Note: The java doc on various boxes has the limited description which was already present. In future I am planning to add proper small description for each box (from MP4 spec).

Not included in this CL:
1. Order of element correction as it will show lot of changes and might create confusion with other minor changes.
2. Correction in test cases (Only some renaming).

This is needed for constrained multi-asset to shift the timestamps of
the media items that are not the first in the sequence.

Also, omit the "actual" label from output files, as this boilerplate isn't necessary
(it doesn't disambiguate between any other saved filename like "expected").

PiperOrigin-RevId: 502378188

This should make debugging much easier as values will be more human-readable.
Before this CL, one needed to reference MediaFormatUtil to check the
colorSpace/colorTransfer/colorRange values and make sure values were as
expected.

Makes GlEffectsFrameProcessorPixelTest slightly more modular in preparation for
copying this into transformer/mh.

Refactoring change. No functional change intended.

Frame cache compensates for the fluctuation in frame processing times.

Imagine a frame takes 10ms to process, and the interval between two frames is
33ms. The third frame took 40ms to process.

If we don't have frame cache:
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms,
- Release frame 2 at t=33ms
- We start processing the third frame at t=33ms
- The third frame is due presentation at t=66ms
- But frame 3 is available at t=73ms, late

If we have a frame cache of say 3 frams,
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms
- Start processing frame 3, ready at t=50ms
- Release frame 2 at t=33ms
- Start frame 4, ready at t=60ms
- Frame 3 is due presentation at t=66ms
- Frame 3 isn't late

Previously, after calling MCVR.setOutput() with null, `frameProcessorManager`'s output surface is cleared. What was unexpected is `ExoPlayerInternal` notifies a zero output resolution after clearing the output surface. This zero resolution causes FrameProcessor to fail.

Move BitmapTestUtil from media3.effect to media3.test.utils.

This allows this class to be accessed from both transformer and effect tests.

Refactoring change. No functional change intended.

Each error will make the output be a solid color with a unique color.

Notifies event listener of FrameProcessor's new output size to layout the
PlayerView

This class may be removed soon, but in the meantime clarify this method's
javadoc summary fragment to make it marginally clearer that this only affects
the "displayed" height instead of the "encoded" height.

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.

PiperOrigin-RevId: 501244974

This improves performance and makes the code more intuitive.

PiperOrigin-RevId: 501220234

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.
