Removed `Android.mk` and `Application.mk`, allowing `CMake` to run directly from the build.gradle file. Users no longer need to check out `NDK` or depend on it, simplifying the usage of the Flac extension.
Also fixed a copy-pasted comment in `CMakeLists.txt` of Opus and IAMF.

We need to rebuild any native components of the app to prevent crashes on devices with 16 KB page support.
Tested on a device that supports 16 KB pages and runs Android 15, as well as on older Android devices.

The version and flags are stored in a single integer,
with the version in the higher 8 bits and the flags in
the lower 24 bits. The version should be 1 and the
flags should be 0.
Surprisingly the incorrect value was ignored by many
players and hence the bug was never caught.
With the bug, the video does not play on
`Samsung Galaxy S22 Ultra` and works well
after fixing the bug.

Minor improvement to allow an Media3 browser to pass extras
when connecting the initial browser in `MediaControllerImplLegacy`.
Before this change an empty bundle was sent. After this change
the connection hints of the `Media3 browser is used as root hints
of the initial browser that connects when the Media3 browser is
built in `MediaBrowser.buildAsync`.

This helps avoid overflows in intermediate calculations.
Verified the value in the test using `BigInteger`:
```

$3 ==> 405323966463344

The implementation of these methods was updated from direct java integer
arithmetic in 885ddb167e.
In this change, `RoundingMode.FLOOR` was used to try and maintain
compatibility with java integer division. This was incorrect, because
java integer division uses `DOWN` (i.e. towards zero), rather than
`FLOOR` (i.e. towards negative infinity) semantics.
This change fixes the compatibility.
The dump file changes in this CL relate to tests that exercise edit
list behaviour. This involves manipulating negative timestamps, which
explains why they are impacted by this change.

- Updated `DefaultTrackSelector.SpatializerWrapperV32.canBeSpatialized` to handle IAMF format.
- Modified `isAudioFormatWithinAudioChannelCountConstraints` to check for `NO_VALUE` of `channelCount` to improve readability.
Note: `DefaultTrackSelector.SpatializerWrapperV32.canBeSpatialized` is not triggered for the IAMF format due to the unset channel count (`Format.NO_VALUE`). The update ensures completeness.

Object-based audio is more efficient and flexible than channel-based audio, supporting a broader range of devices. This update makes `DefaultTrackSelector` prefer object-based audio when other factors are equal, ensuring its use whenever possible.

When calling `MediaController.getCommandButtonForMediaItem(MediaItem)`
command buttons with custom commands that are not available
shouldn't be advertised to the controller when connected to
a Media3 session.
In contrast, when connected to a legacy session, available commands
are not enforced when advertising commands. Similarly, when sending
a custom commands that is referenced by a command button for media
items, sending is permitted without the command being available.
This is required because available commands match to custom actions
in `PlaybackStateCompat` of the legacy session. Adding commands for
media items to custom action of the `PlaybackStateCompat` would
interfere with other use cases.

This was missed in da724c8cc4
I tried to write a test for this, but got stuck crafting valid test
data. I was able to create a new fragmented MP4 file containing only a
TTML track:
```shell
$ MP4Box -add simple.ttml -frag 2000 sample_fragmented_ttml.mp4
```
Then I tried naively removing the `ftyp` and `moov` boxes with a hex
editor, but using this in `FragmentedMp4ExtractorNoSniffingTest` gave
me an `EOFException` that I didn't get to the root cause of.

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.

PlaybackVideoGraphWrapper will soon contain an input and an output video

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.

Just clearing the overrides only helps if a text override was
previously set. If the text is shown because of app defined track
selection parameters for language or role flags, the "none" button is
currently not working and we need to clear these flags explicitly.

The workaround in ExternalTextureManager.forceSignalEndOfStream
was being applied even when the decoder did output all frames, and only
the GL pipeline was slow.
This change ensures that workaround is not applied when the decoder
has already produced all output frames.

If a codec received the EOS signal and already returned the last
output buffer, we should expect the output EOS very quickly. If
it doesn't arrive within 100ms, we can proceed to end the stream
manually without waiting any further to prevent cases where the
codec is completely stuck otherwise.
