This method is no longer needed since we added SubtitleConfiguration#id
in https://github.com/androidx/media/commit/59d98b9a4e2381647f3e4552b6935bcca1be6f89.

DownloadHelper is in the ExoPlayer module, so there's no reason
why it can't use ExoPlayer specific track selections. That said,
we want our UI components to operate on generic
TrackSelectionParameters, and we want such UI components to be
useful for selecting tracks for download. To keep this interop,
it's necessary to have DownloadHelper accept generic
TrackSelectionParameters, or to require application code to
convert them. The first approach seems preferable!

This constructor always does the wrong thing for non-adaptive groups
containing more than 1 track, because it'll incorrectly generate an
adaptive selection. Replace it with a constructor for specifying a
single track within the group instead.

Only log GL exceptions in GlUtil if they aren't thrown. Otherwise,
it's up to the caller whether or not to log them to avoid logging them
twice.

Destroying the context destroys all of OpenGL (see
https://www.khronos.org/opengl/wiki/OpenGL_Context), so deleting
textures is redundant.

This test tests the same cases as the FrameEditorDataProcessingTest
as currently the main FrameEditor functionality is to apply a
transformation matrix using a TransformationFrameProcessor.

Test list can be structured so tests don't need to be in different
classes, cleaning up the location of new test cases.

As evidenced by the somewhat awkward logic in PlayerControlView, the
previous design wasn't very friendly to expected usage. There will be
more usage when the track selection dialog components are migrated,
which would be similarly awkward without this change.

This is consistent with the new MediaSessionStub that accepts page index 0
and the JavaDoc of legacy and new service callbacks.

When a live stream is joined while ads are already playing, the LOADED event is
missed and we don't have ad information for those ads in the ad group that are
before the ad index at which we joined. This way we can clip the duration when we
receive the LOADED event for the last ad in the group. This fixes the problem of
the playback controls being hidden when content resumes after the ad group.

There's no media3 equivalent to the
`com.google.android.exoplayer:exoplayer` dependency.

We use SSIM to measure the transcoding quality between. SSIM is a widely used
tool that compares the luma channel between two images, and generates a score
from 0 to 1 that indicates "how similar" the two images are.

In `SsimHelper`, we decode the two videos, extract matching frames and
calculates the mean SSIM (SSIM averaged all matching frames) for both videos.
Matching frames are referred to as "comparisonFrame" in the CL, which is
selected based on the frame number and a user-set comparison interval.
For instance, if the interval is 7, then every seventh frames are compared.

We use MediaCodec/MediaExtractor to decode the video, and use ImageReader to
extract the decoded frame.

The SSIM calculation logic is a inspired by and modified from the CTS
[MSSIMMatcher](https://cs.android.com/android/platform/superproject/+/master:cts/tests/tests/uirendering/src/android/uirendering/cts/bitmapcomparers/MSSIMComparer.java;l=1?q=mssimcom)
that has some errors and extra features we don't need (like handling RGB
images).

Adds TranscodeQualityTest to ensure high quality transcoding.

When investigating how 'bad' a failure is, it's useful to see the diff
between input and output bitmaps.

The command is not needed, because the specified branch is already the
default branch on GitHub so will be checked out by clone automatically.

The AsyncronousMediaCodecAdapter should call MediaCodec.start()
on the same thread it calls MediaCodec.flush(), i.e. the playback
thread. This change removes the experimental flag that allowed
calling MediaCodec.start() from the callback thread.

The flag was flipped to true already.
