Both interfaces are not really needed as the methods can be called
on the respective classes directly. This also avoid error-prone
situations where classes define to/fromBundle methods with parameters
that should be used instead of the parameter-less version.
Also deprecate all existing CREATOR static instances and make the
corresponding fromBundle method public where needed.

* Rename method f(n) to a more helpful name.
* Move the private inner class to the bottom.
* Move public fields before private fields but below the static field.
* Make `private ParsableByteArray data` final.
* Make sure `parseSequenceHeader` can only be called once.
DefaultTrackSelector now has all logic necessary for selecting an
image track.
If isPrioritizeImageOverVideoEnabled is set to true, image track will
try to be selected first and a video track will only be selected if no
image track is available. If isPrioritizeImageOverVideoEnabled is set
to false, image track will be selected only if video track wasn't
selected.

BundleableUtil is the only class that really depends on the type
inheritence from Bundleable. However, it only needs this as a way
to define Function<T, Bundle> and Function<Bundle, T>, which could
just be passed in as parameters as it's already done for some of
these methods.
Also rename the class to BundleCollectionUtil accordingly.

Unfortunately we can't fail any more obviously at this point, because
manifests often contain config for multiple DRM schemes, and when
parsing the manifest we don't know which scheme is going to be used for
playback. It would be unreasonable to fail playback due to incomplete
ClearKey config if playback was otherwise going to succeed using e.g.
Widevine.

This has been documented to work since this class was created, but until
now we were always trying to resolve using the current application's
`Resources.getIdentifier` method. This commit changes to resolve to the
other app's `Resources` object if the package name doesn't match the
current package.
This will only work if the current app has package-visibility to the
destination package: http://g.co/dev/packagevisibility
This is hard to test because to do so robustly requires being able to
guaranteed that another test APK will be installed with a known raw

This change applies to standalone WebVTT files linked directly from the manifest.

When transmuxing, we usually only need to offset the timestamp by the position of a mediaItem in a sequence.

The events happens in the following order, assuming two media items:
1. First media item is fully decoded, record the last frame's pts
- Note frame processing is still ongoing for this media item
2. Renderer sends `onOutputFormatChanged()` to signal the second media item
3. **Block sending the frames of the second media item to the `VideoSink`**
4. Frame processing finishes on the first media item
5. The last frame of the first media item is released
6. **Reconfigure the `VideoSink` to apply new effects**
7. **Start sending the frames of the second media item to the `VideoSink`**

Some devices supporting Performance Points for decoder coverage are missing coverage over the CDD requirements for H264. For these cases ExoPlayer should fall back to legacy resolution and frame rate support checks.

This change moves the handling of any media button event into
`MediaSessionImpl.onMediaButtonEvent(intent)`. This includes
the double click handling from `MediaSessionLegacyStub`.
The advantage is that everything is in one place which allows
to offer `MediaSession.Callback.onMediaButtonEvent` with which
an app can override the default implementation and handle media
buttons in a custom way.
Media button events can originate from various places:
- Delivered to `MediaSessionService.onStartCommand(Intent)`
- A `PendingIntent` from the notification below API 33
- An `Intent` sent to the `MediaButtonReceiver` by the system dispatched
to the service
- Delivered to `MediaSessionCompat.Callback.onMediaButtonEvent(Intent)`
implemented by `MediaSessionLegacyStub` during the session is active
- Bluetooth (headset/remote control)
- Apps/system using `AudioManager.dispatchKeyEvent(KeyEvent)`

Since DEFAULT_MAX_CHANNEL_COUNT was increased from 8 to 10,
getMaxSupportedChannelCountForPassthrough always throws if its loop
enters its second iteration (channelCount of 9). This is due to
Util.getAudioTrackChannelConfig returning CHANNEL_INVALID when passed a
channelCount of 9, and setting CHANNEL_INVALID as the AudioFormat's
channel mask throws an exception.
This change skips each iteration where CHANNEL_INVALID is returned.
HttpEngine was added in Android SDK 34. This DataSource is preferable to the DefaultHttpDataSource if supported as it offers better performance and more modern features.

The `PreloadMediaSource` has below two new public methods that suppose to be called by the app:
* `preload(long)` allows the apps to preload the source at the passed start position before playback. The preload efforts include preparing the source for a `Timeline`, creating and caching a `MediaPeriod`, preparing the period, selecting tracks on the period and continuing loading the data on the period.
* `releasePreloadMediaSource()` allows the apps to release the preloaded progress.
The `PreloadMediaPeriod` is designed to facilitate the `PreloadMediaSource` for the preloading work. It has a new package-private method `selectTracksForPreloading` which will cache the `SampleStream` that corresponds to the track selection made during the preloading, and when the `PreloadMediaPeriod.selectTracks` is called for playback, it will uses the preloaded streams if the new selection is equal to the selection made during the preloading.
Also add a shortform demo module to demo the usage of `PreloadMediaSource` with the short-form content use case.

This change moves the release timestamp adjustment logic out of
MediaCodecVideoRenderer and into a standalone component, the
VideoFrameReleaseControl. The plan for VideoFrameReleaseControl is to use
it:
- from MediaCodecVideoRenderer, when ExoPlayer plays video in standalone

- from the CompositionPlayer's DefaultVideoSink, when CompositionPlayer
supports multiple sequences.
- (temporarily) from the CompositionPlayer's custom ImageRenderer while
we are implementing single-sequence preview, which is an intermediate
milestone for composition preview.

Media button event coming from the `MediaSessionService` are delegated
to the `MediaSessionImpl` and then sent to the session by using the
`MediaSessionStub` directly instead of using the `MediaController`
API.
Splitting the `MediaController.Listener` and `Player.Listener` in
`MediaNotificationManager` got reverted, and both listener are set to the
controller as before. This reverts the change that introduced a
different timing behaviour. It still holds, that a listener
registered on a `MediaController` that calls a method like `play()` is
called immediately and before the call has arrived at the player. This
change works around this behaviour from the library side by calling
`MediaSessionStub` directly with a `ControllerInfo`.

Previously, we calculated the next playlist reload time by adding the target duration (or half of it, depending on whether there is a real update in the new playlist snapshot) from the last load completion time, which makes the reload interval as long as `targetDuration(or half of it) + lastLoadDuration`. While still complying to the standard that "the client MUST wait for at least the target duration before attempting to reload the Playlist file again", this could cause buffering when the playback position is close to the end of live window. This change is to calculate the reload interval accurately by not adding the term `lastLoadDuration`.

If the `Subtitle` has 'active' cues at `OutputOptions.startTimeUs`, this
change ensures these are emitted in a `CuesWithTiming` with
`CuesWithTiming.startTimeUs = OutputOptions.startTimeUs`. If
`OutputOptions.outputAllCues` is also set, then another `CuesWithTiming`
is emitted at the end that covers the 'first part' of the active cues,
and ends at `OutputOptions.startTimeUs`.
As well as adding some more tests to `LegacySubtitleUtilWebvttTest`,
this change also adds more tests for `TtmlParser` handling of
`OutputOptions`, which transitively tests the behaviour of

When the controller of the `MediaNotificationManager` is disconnected,
the session is removed from the service without checking whether the
session hasn't already been removed. This caused flakiness in `MediaSessionServiceTest.addSession()`.

the controller can't make an assumption whether the session is still

Future.isDone and getDone doesn't imply the Future was successful

cancellation. Cancellation of these variables usually happens in

In some streaming scenarios, like offload, the sink may finish writing buffers a bit before playback reaches the end of the track. In this case a player may pause while in this 'stopping' state.
The AudioTrackPositionTracker needs to update the cached values it uses to calculate position in the `PLAYSTATE_STOPPED`/`PLAYSTATE_STOPPING` states if pause/play are called during this period.
PiperOrigin-RevId: 571345914
In offload mode, `AudioTrack#stop()` will put the track in `PLAYSTATE_STOPPING` rather than `PLAYSTATE_STOPPED`. The difference in state means that `AudioTrack` can be paused and played during this 'stopping' period.
Currently, if `AudioTrackPositionTracker#handleEndOfStream()` has been called then `DefaultAudioSink` in `pause()` won't call `AudioTrack#pause()`. `AudioTrack#pause()` should be called in this case if in offload mode.

This gets rid of the reliance on the decode only flag that is still
set on input buffers to the decoder if they are less than the start
time.
We still need to set and check the decode-only flag in SimpleDecoder
to ensure compatbility with custom decoders that use the flag while
it's not fully removed.
PiperOrigin-RevId: 570736692
The interface requires the implementation to return null if the
decode-only flag is set. So instead of setting the flag and returning
null, we can simply not call the method and assume it's null.
The only reason where this wouldn't work is if the metadata format
has keyframe-like logic and requires previous metadata to decode
the next one. This is not something we came across before and it seems
ignorable. If that feature is needed in the future, we should instead
add a method to MetadataDecoder to set the first output timestamp.

The library already maintains the subscribed controllers internally. This
change adds `MediaLibrarySession.getSubscribedControllers(mediaId)` to
access subscribed controllers for a given media ID.
To accept a subscription, `MediaLibraryService.Callback.onSubscribe` is
required to return `RESULT_SUCCESS`. So far, this isn't the case for the
default implementation of the library.
This change implements `Callback.onSubscribe` to conditionally
provide `RESULT_SUCCESS`. The default calls `Callback.onGetItem(mediaId)` to
assess the availability of the media item. If the app retruns `RESULT_SUCCESS`
with a browsable item, the subscription is accepted. If receiving a valid item
fails, the subscription is rejected.

Changes
---
- Added `removeOfflineLicense(byte[])` and `getOfflineLicenseKeySetIds` and consumed them in their implementations
Background
---
- These APIs will help in addressing an increasing amount of `java.lang.IllegalArgumentException: Failed to restore keys: BAD_VALUE` which is our top playback error in our app
- Based on our discussion with Widevine team and [this exoplayer issue](https://github.com/google/ExoPlayer/issues/11202#issuecomment-1708792594)
- TL;DR: The failure occurs on startup if the user has 200+ offline licenses, we would like to add the functionality to remove offline licenses
**Note: Why we want these APIs in ExoMediaDrm and not in OfflineLicenseHelper**
- As per the issue above, we would like to access these 2 public APIs in MediaDrm that don’t exist in `OfflineLicenseHelper` or `ExoMediaDrm`
- APIs interested in:
- [MediaDrm#removeOfflineLicense()](https://developer.android.com/reference/android/media/MediaDrm#removeOfflineLicense(byte%5B%5D)): To remove offline license
- [MediaDrm#getOfflineLicenseKeySetIds()](https://developer.android.com/reference/android/media/MediaDrm#getOfflineLicenseKeySetIds()): To see number of offline licenses on startup
- We use `OfflineLicenseHelper` to download license for L1 and we don't interact with `ExoMediaDrm` directly. But for the alternate Widevine integration, we directly depend on `ExoMediaDrm` APIs to override and call CDM Native APIs.
- We would like to have the functionality of removing offline licenses for both integration which would need access to above APIs in `ExoMediaDrm`.

MediaCodecRenderer has already been updated to not rely on the

Before this change, media button events are routed from `onStartCommand`
of the `MediaSessionService` to the `MediaSessionCompat`, resolved by
the legacy library to a session command called on
`MediaSessionCompat.Callback` from where the command is delegated back
to the Media3 session.
With this change the keycode is resolved directly to a Media3 command
that is sent to the session through the media notification controller
of the session.
After this change, a playback or custom command sent to the session
from a notification, either as a pending intent (before API 33) or as
a legacy session command, look the same and the caller is the
media notification controller on all API levels.

With this change, the notification controller that is connected by
`MediaNotificationManager`, is used as a proxy controller of the
System UI controller. An app can use the proxy at connection time
and during the lifetime of the session for configuration of the
platform session and the media notification on all API levels.
This includes using custom layout and available player and session
commands of the proxy to maintain the platform session (actions,
custom actions, session extras) and the `MediaNotification.Provider`.
The legacy System UI controller is hidden from the public API,
instead the app interacts with the Media3 proxy:
- System UI is hidden from `MediaSession.getConnectedControllers()`.
- Calls from System UI to methods of `MediaSession.Callback`/
`MediaLibrarySession.Callback` are mapped to the `ControllerInfo`
of the proxy controller.
- When `getControllerForCurrentRequest()` is called during an operation of
System UI the proxy `ControllerInfo` is returned.
