This refactors the `supportsFormat` method on the MediaCodecVideoRenderer to be a static method that can be called from external components to determine if a video format is supported by the device renderers. Since `context` is the only component that is part of the MCVR, it can easily be obtained externally and passed to the method.
This can help optimize format support decisions ahead of time of a player having been instantiated, such as removing unsupported representations from a dash manifest.
This could also be done for the MCAR but would also require passing in the AudioSink and isn't required at this time.
This change is a no-op, because
`SubtitleTranscodingExtractorOutput.seekMap` forwards directly to the
delegate implementation, but it seems clearer to always use the
wrapper.
Also remove a no-op assignment in `MatroskaExtractor`.
This is a follow-up to Issue: androidx/media#1779 where I manually checked every
implementation of `Extractor.init` for a similar mistake.

These Uris are not widely supported yet and were only meant to be
used with content Uris. Restricting this more tightly allows
controllers to use these Uris more easily as they have a stricter
guarentee on what it's needed to load these Uris. Media session
apps with different types of Uris can convert them by setting up
a ContentProvider if needed.

This CL also fixes EOS handling to account for not-yet-copied samples in
`remainingInputToCopyFrameCount`, which would throw off the final output
sample count calculation.
For testing, we allow a tolerance of 0.000017% drift between expected
and actual number of output samples. The value was obtained from running
100 iterations of `timeStretching_returnsExpectedNumberOfSamples()` and
calculating the average delta percentage between expected and actual
number of output samples. Roughly, this means a tolerance of 40 samples
on a 90 min mono stream @48KHz.

If a codec received the EOS signal and already returned the last

it doesn't arrive within 100ms, we can proceed to end the stream

The buffered position was last updated before the beginning of
the renderer loop in doSomeWork. As the loading happens on a
background thread, it may have progressed further already
depending on how long it took to run the renderer loop.
It's slightly more correct to pass in an updated value to
shouldStartPlayback so that playback can start quicker if the
buffering is particularly fast.

We began to use a different preload thread than the main thread in the `DefaultPreloadManagerTest`, then in the test execution, we should also ensure that the events queued on the preload looper have been executed.
Also, there is an edge case also causing flakiness. Assume that `DefaultPreloadManager` is preloading source B, then the app invalidates and triggers another sequence of preloading, say they are A, B and C. There is possibility that source B finishes preloading (started before `invalidate`) when A starting to preload, then `onPreloadSkipped` will be triggered for source B instead of `onPreloadCompleted`. However, the functional block inside of `onPreloadSkipped` is dispatched asynchronously, and by then it's possible that B starts to preload again at the consequence of A being completed, then the functional block just mentioned may think that the current source matches at B, and will advance the current preloading source to C, without informing the `Listener.onPreloadCompleted` for it. As the result, the `Listener.onPreloadCompleted` can never be triggered for B for the second sequence. To fix this, we should prevent the functional block in `onPreloadCompleted`, `onPreloadError`, `onPreloadSkipped` to be even dispatched, when the source doesn't match the current preloading one.

When a Media3 controller calls play on a Media3 session, the call
is currently not routed through the platform session at all.
This means the usual exemption to start a FGS for media controller
interactions is not triggered.
We can manually ensure this exemption is given by sending a custom
platform command to the session. The Media3 session will never
receive this command as it's not a known Media3 custom command.
Sessions will see a single onConnect call with a platform controller
from the sender app though. We can prevent this on newer versions of
the code by dropping the onCommand call early.

The max number of commands for media items of a browser or controller
can be configured with `setMaxCommandsForMediaItems(int)` on
`MediaController.Builder` and `MediaBrowser.Builder`. An app that has
only limited space for displaying commands can hint this limit to the
session.
A session can receive the value of a connected browser or controller
through `getMaxCommandsForMediaItems()` of a `ControllerInfo` that
is passed into every callback method. The session can then pick the most
sensible commands instead of making the browser app truncating the commands
rather randomly.
When a `MediaBrowser` is connected against a legacy `MediaBrowserServiceCompat`,
the max number of commands is automatically added to the root hints. Conversely,
the value passed in with the root hints to `MediaLibraryService` by a legacy
`MediaBrowserCompat`, is read into `ControllerInfo` like for a Media3 browser.

Note that unlike the legacy implementation, custom media items
commands can be used for any media items with Media3 API. This
includes `MediaItem` instances that are received from sources
different to `MediaLibraryService` methods.
Hence when connected against a Media3 session these custom commands
can be used with a `MediaController` as well as with a `MediaBrowser`.
Interoperability with `MediaBrowserServiceCompat` will

This check is also done when setting a surface on ExoPlayerImpl,
but by the time we configure the codec the surface may have become
invalid (e.g. when it is destroyed). Even though we immediately remove
a destroyed surface, we could still accidentally use it before the
removal is processed. To avoid these edge cases, we can simply not
configure the codec with an invalid surface.

Access is package-private and it will allow the media controller logic
to interact with the underlying platform session directly if needed.
Interop: When a MediaController connects to an older session (before this
change), it won't get the platform token from the session directly.
Many controllers will be set up with a platform or compat token though
and we can simply keep the already known token and use it. The only
cases where we still don't have a platform token in the MediaController
are the cases where the controller is created with a SessionToken based
on a ComponentName.

disabled. To enable preloading,
`ExoPlayer.setPreloadConfiguration(PreloadConfiguration)` can be

`LoadControl` determines when to preload with its implemenation of `shouldContinuePreloading(timeline, mediaPeriodId, bufferedDurationUs)`.

the player isn't currently loading for playback. Apps can override this

This CL adds `SonicTest` and `RandomParameterizedSonicTest` as
initial basic unit testing for `Sonic.java`. The tested scenarios
do not necessarily verify a correct implementation of Sonic, but rather
hope to catch any behaviour change from the current implementation.
The change includes a small fix for a lossy simplification and also
checks whether the output sample count matches the expected drift from
the truncation accumulation error present in Sonic's resampler. This is
important as pre-work for fixing issues with unexpected durations within
`SonicAudioProcessor` and `SpeedChangingAudioProcessor` that cause AV
sync issues for speed changing effects.
This is a partial roll forward of e88d6fe459, which was rolled back in
873d485056.

AudioTrack doesn't automatically ramp up the volume after a flush
(only when resuming with play after a pause), which causes audible
pop sounds in most cases. The issue can be avoided by manually
applying a short 20ms volume ramp, the same duration used by the
platform for the automatic volume ramping where available.
Together with the already submitted 6147050b90, this fixes the
unwanted pop sounds for most cases in the desired way. It only
leaves two cases that are not handled perfectly:
- If the media file itself contains a volume ramp at the beginning,
we wouldn't need this additional ramping. Given the extremely
short duration, this seems ignorable and we can treat it as a
future feature request to mark the beginning of media in a special
way that can then disable the volume ramping.
- For seamless period transitions where we keep using the same
AudioTrack, we may still get a pop sound at the transition. To
solve this, we'd need a dedicated audio processor to either ramp
the end of media down and the beginning of the next item up, or
apply a very short cross-fade. Either way, we need new signalling
to identify cases where the media originates from the same source
and this effect should not be applied (e.g. when re-concatenating
clipped audio snippets from the same file).

When sending a custom command with `browser.sendCustomCommand` when
connected to a legacy browser service, the custom command was delivered to `MediaSessionCompat.Callback.onCustomAction` instead of the service method
`onCustomAction`. The difference is that the service version can return an
async response with a bundle, while the session callback version doesn't
have a return value.
Hence, the service method was never called and it wasn't possible to send
a reponse or signal an error back to the browser. The resulting
`ListanableFuture` simply always immediately resolved to a success.
This change overrides `ListenableFuture<SessionResult> sendCustomCommand(SessionCommand command, Bundle args)` in
`MediaBrowserImplLegacy` to use the `MediaBrowserCompat` method to send
instead of the `MediaControlleCompat` method that was used by the subclass
`MediaControllerImplLegacy`. This involves the service callback instead of the
session callback and enables `MediaBrowser` to get the actual return value
from the legacy service.

- Added logic to parse media duration from the `mdhd` box for accurate frame rate calculation.

- Verified accuracy with tools like `mediainfo` and `ffprobe`.
Issue: androidx/media#1531
**Note**: The slight difference in frame rate values in dump files that aren’t MP4s with an edit list or fragmented MP4s isn’t due to differences in `tkhd` and `mdhd` duration values (which should be identical for non-edited or non-fragmented files). Rather, it’s because they are calculated using different timescales. The `mvhd` box defines a global movie timescale, which is used for the track's `tkhd` duration. Meanwhile, each track’s `mdhd` box defines its own timescale specific to its content type, which we now use for more accurate frame rate calculation.

The muxer might not have accepted the first sample, if it
is waiting for audio track.
This bug causes issue when
1. VideoSampleExporter gives first sample (timestamp = 0) to the muxer.
2. Muxer does not write it because its waiting for audio track.
3. The video pipleline has processed all the sample and they are ready
to be consumed.
4. VideoSampleExporter fetches the next available sample from encoder (which is still with timestamp = 0) but it changes its timestamp to last timestamp because VideoSampleExporter thinks it has muxed the sample at timestamp zero, but in reality it hasn't. This is because the flag `hasMuxedTimestampZero` is set when queueing the input, rather than actually muxing the input.
This scenario can happen when video is processed much faster than
the audio.

Previously, track IDs were added to `trackIndicesPerSampleInQueuedOrder`
even when the sample was not committed. This caused issues where attempts
to read samples from the `SampleQueue` returned `C.RESULT_READ_NOTHING`,
which led to an exception being thrown due to the assumption that samples
were available to read.
This fix updates the logic to track sample commits by comparing the write index before and after calling `SampleQueue.sampleMetadata`. Track indices are only added if the sample was committed, ensuring accurate sample handling and avoiding exceptions.

LAST_SAMPLE_DURATION_BEHAVIOR_SET_FROM_END_OF_STREAM_BUFFER_OR_DUPLICATE_PREVIOUS
This CL also combines LAST_SAMPLE_DURATION_BEHAVIOR_SET_FROM_END_OF_STREAM_BUFFER
and LAST_SAMPLE_DURATION_BEHAVIOR_DUPLICATE_PREVIOUS.
The reason for combining the two enums is that, when the option
to use END_OF_STREAM_BUFFER is selected and if the EOS buffer is
not provided then the muxer anyways fallbacks to duplicate
duration behavior.
The last sample with 0 durations seems less useful so
change the default behavior to non-zero duration.
This will also match the behavior with MediaMuxer.
