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

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

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.

We need to access internal state to work around resources not being released on
old API versions. Add a reference to the bug about this and suppress the lint
warning.

All (later customizable) GlFrameProcessors after the
ExternalCopyFrameProcessor receive their input from a normal OpenGL
texture not an external texture, so they won't need to worry about
the textureTransformMatrix.

getCurrentTrackGroups and getCurrentTrackSelections are
retained for now, but moved from Player to ExoPlayer, to
ease the transition for some application code that currently
uses these methods.

There are two major blockers to this test:

- H265 muxing is not available for API<24, so setting video mimeType to H265
  will fail on those devices.
- AMR audio encoding is buggy on some device and it's not a widely used format.

The solution: use a video that is encoded with AVC/MP3, to ensure transcoding
to AVC/AAC.

Re-enable tests that have no muxer support for timestamps going backwards.

Tests running on the B-frame sample will be added in a future commit.

We use the `createForCodec` method that does not take a `MediaFormat` during
transformation, the error message always includes "no configured MediaFormat",

The muxer doesn't support HEVC below API 24. The is documented in
the TransformationRequest javadoc and the Transformer.Builder will
throw if HEVC is requested below API 24 so the option should not
be part of the demo for those devices.

isTypeSupportedOrEmpty is very specific and a little hard to
understand unless you know the one thing it's useful for. This
commit replaces it with isTypeSupported, which can be used in
conjunction with the recently added containsType method.
