The tests were flaky because CompositionPlayer registers audio sequences'
formats to the audio pipeline in first-come-first-serve order. With the change
in bc8d82355f, the audio format is deterministic.
The test is turned off in 060356ea00

Sonic would accumulate truncation errors on float to int conversions
that caused the final output sample count to drift noticeably, by
hundreds of samples on streams of a few minutes of length. The fix now
keeps track of the truncation error and compensates for it.
Other small fixes include eliminating lossy operations (e.g. int
division) and using doubles instead of floats for resampling where
helpful.
This CL also introduces `SonicParameterizedTest`, which helps test
resampling on an arbitrary number of randomly generated parameters,
with random sample data. `SonicParameterizedTest` uses `BigDecimal`s
for calculating sample count values, as to avoid precision issues with
large sample counts.

When processing edit lists in MP4 files, the media start position may be a non-keyframe. To ensure proper playback, the decoder must preroll to the preceding keyframe, as these preroll samples are essential for decoding but are not rendered.

In case of negative PTS workaround, instead of disallowing all cases where samples are not in presentation order, we now validate that the first sample's presentation time is the smallest. This adjustment allows for correctly applying an offset to ensure all samples have a presentation time >= 0.

Limit input image size in Transformer to be less than 4096x4096.
For very large images, this can reduce memory usage substantially,
and stays away from `GL_MAX_TEXTURE_SIZE` - often 4096

These tests do not test performance. Moving them out of this directory
ensures they are run on emulators and on all physical devices.

MediaMuxer doesn't support B-frame before API 25.
The fix is added only in those test which appeared in triage failure.
It can be added to other tests as they are discovered.

Make ByteBufferGlEffect public.
Build a speed test, and end to end test that verify
frames can be copied to CPU-accessible ByteBuffer

Disable assertions and make sure playback passes.
The flake is caused by having different sequences starting with MediaItems of
different audio format, and it's undefined behaviour as to which one CompositionPlayer chooses to use.

These tests do not test performance. Moving them out of this directory
ensures they are run on emulators and on more than 1 physical device.

The logic was assuming that the shader program was only flushed when
seeking. This is true if a single renderer is used but, with multiple
renderers, the shader program can be flushed at the transition.
This change is necessary to make the test pass for prewarming because 2
video renderers will be used in that case.

The audio mixing is not deterministic on real device testing because of
threading, but runs deterministically on robolectric tests

Use ExoPlayer dynamic scheduling to reduce the render() interval for
older API devices where `DefaultCodec.getMaxPendingFrameCount()` is set
to 1 in order to prevent frame drops.
Controlled via API on DefaultDecoderFactory.
Add TransformerForegroundSpeedTest that mimics transcoding while the app
is in foreground.

App users can choose arbitrary data that might not be
anticipated by developers. Transformer shouldn't `checkState` based on
media data or file type -- report an error for unsupported data instead.
Public API change `ImageAssetLoader` needs to parse MIME type and now accepts
`Context` as parameter.

Package-private until API is more useable.
Similar to frame analyzer mode: uses ImageReader instead of an encoder,
and no muxer.

Transformer.experimentalSetMaxFramesInEncoder controls max number
of frames in encoder.
VideoFrameProcessor now allows delayed releasing of frames to Surface,
while still using the original presentation time.
VideoSampleExporter can now configure video graphs to not render frames
automatically to output surface.
VideoSampleExporter.VideoGraphWrapper tracks how many frames are ready
to be rendered to Surface, and how many frames are already in-use by encoder.
