Resampling as a term is overloaded, however it was raised as a
confusing term in a meeting recently, as the 1P team initially thought
this would change the sample rate. The naming of this `AudioProcessor`
now matches `ToInt16PcmAudioProcessor`.

Added onSetMediaItems callback listener to allow the session to modify/set MediaItem list, starting index and position before call to Player.setMediaItem(s).

Added conditional check in MediaSessionStub.setMediaItem methods to only call player.setMediaItem rather than setMediaItems if player does not support COMMAND_CHANGE_MEDIA_ITEMS

Clarify that we always output on full range colors, and don't handle
hdrStaticInfo input yet.

This makes it implicitly clear that if the value of a getter changes due
to a change in command availability then the listener will be invoked,
without needing to explicitly document every command on every listener
method.

We stop estimating new position when pausing until we
receive a new position from the player. However, this
means that we will continue to return a possible stale
previous position. Updating the current position before
pausing solves this issue.

We currently only document it for the getCurrentMediaItem(), but
the command was always meant to cover all information about the
current media item and the position therein.

To correctly hide information for controllers, we need to filter
the Timeline when bundling the PlayerInfo class if only this
command is available.

Usages of the deprecated methods in Transformer.Builder will be removed
in a follow-up CL.

PiperOrigin-RevId: 502889423

This is to avoid regressions introduced by removing the convenience
methods from TransformationRequest.

PiperOrigin-RevId: 502864512

When bundling PlayerInfo, we need to remove information if the
controller is not allowed to access it. This was only partially
done at the moment.

TESTED: Manually verified the ColorInfo is propagated when VSP is used.

To always generate silent audio, `removeAudio(true)` can be used in conjunction.

This class will be used in a follow-up CL.

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.

PlayerWrapper advertises PlaybackStateCompat actions to the legacy
MediaSession based on the player's available commands.

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").

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.

The command check for setDeviceMuted was wrong.

PiperOrigin-RevId: 502355332

This player didn't fully check all player commands before calling the
respective methods.

PiperOrigin-RevId: 502353704

The method to dispatch actions in MediaControllerImplBase takes
a Player.Command, but the value is only used to check if we
are setting a surface and need to handle the special blocking
call. This can be cleaned up by removing the parameter and calling
a dedicated blocking method where needed. This also ensures we
have to mention the relevant Player.Command only once in each
method.

PiperOrigin-RevId: 502341862

This avoids throwing exceptions for correct (but deprecated) Player
method invocations.

PiperOrigin-RevId: 502341428

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.
