`findDecoder/EncoderForFormat` seem to be more restrictive than querying
`MediaCodecList` as done for playback, and it's not clear that the cases where
no codec is found correspond to actual cases that would fail given that it
seems this returns an empty string for many cases in production.
Switch to using `MediaCodecUtil` and `EncoderUtil` for querying codecs instead.

MediaMuxer does not support out-of-order video frames API 25. Use
a test file with frames in order in
loopingTranscodedAudio_producesExpectedResult. This is necessary for
tests that transmux video samples.

A passthrough effect allows for testing having an intermediate
effect injected, which uses different OpenGL shaders from having no
effects.

Previously `ChannelMixingAudioProcessor` output float because it was
implemented using the audio mixer's float mixing support.
Move the implementation over to just using the `ChannelMixingMatrix` and make
it publicly visible in the common module so it can be used by apps for both
playback and export.
Also resolve a TODO that no longer had a bug attached by implementing support
for putting multiple mixing matrices to handle different input audio channel
counts, and fix some nits in the test code.
Tested via unit tests and manually configuring a `ChannelMixingAudioProcessor`
in the transformer demo app and playing an audio stream that identifies
channels, and verifying that they are remapped as expected.

Before this CL, SurfaceTexture.onFrameAvailable was used to tell whether a frame
was available in the VideoFrameProcessor's output texture. This was incorrect, as
it would rely on having the texture be written to before the
SurfaceTexture.onFrameAvailableListener is invoked, leading to null-pointer-
exceptions on timeouts.
Instead of using DefaultVideoFrameProcessor different interfaces to set that we
want to output to a texture, and get that output texture, use one interface that
sets a listener, and renders to a texture iff that listener is set. As this
listener is executed on the GL thread, this also allows us to no longer need to
expand visibility for the GL task executor and tasks.

Previously, we always used ImageReader to read from the output of DefaultVideoFrameProcessor, for pixel tests. This has a limitation of not being
able to read HDR contents, so that we couldn't support HDR pixel tests.
Reading from a texture allows us to use glReadPixels to read from
DefaultVideoFrameProcessor, and build upon this to implement HDR pixel tests. We do
still want tests for surface output though, because real use-cases only will output
to Surfaces.
Also, add some tests for outputting to textures, since this test infrastructure is
a bit complex.

The failure reason (no network) will be logged in the test output, but the test will not be marked as failing, rather skipped.

This was trimmed using the Transformer Demo, from ~4 seconds to 300ms
Otherwise, this test file will be quite large, and folks who clone the repo will
have to clone this content as well. Trimming the file also allows the test to
take less time, while still testing the core purpose of the file, to confirm that 4k extraction/decode/GL/encode/muxing works.

This test file used to be remote, which led to various errors in loading the file or timing out during the muxer or overall transformer.

This test is not run on emulator, triage or postsubmit, and does not
provide value to the library in it's current state. It could be
deleted, however it still may have use for analysis of exported files
on MH.

Add format codec info, which can make test skipping checks more similar to the
actual Transformer decoder checks.
Also for the test file, the actual format was 720p, but somehow the file name and
media metadata indicated 1080p. This format mismatch led to some decoding errors,
so fix the format (and associated errors). This also allows us to remove the
exception catch in ForceInterpretHdrVideoAsSdrTest, which was included due to
errors from the incorrect format.

Implement getMediaFormatInteger, a helper method simulating mediaformat.getInteger(name, defaultValue).
This reduces the API 29 restriction from MediaFormatUtil.getColorInfo to API 24, in
particular removing the method-based restriction to a constant-based restriction,
so that we can reduce usage of the API 29 class.
This also allows us to slightly simplify prior use-cases where we'd check
containsKey and getInteger to have a default value.
PiperOrigin-RevId: 511184301
Previously, this was limited to API 29. Expand this to all API versions.
Also, update the test to:
(1) skip based on SDR format input instead of HDR format input
(2) Check the exception message in order to disambiguate between the decoder tone
mapping error, and general video format support error.

Rename ScaleToFitTransformation to ScaleAndRotateTransformation.
This better represents the operations that can be accomplished using this
effect. The name was originally named ScaleToFit* because it's not obvious how
to scale to fit using OpenGL, and this effect handled the scaling to fit in a way that no other MatrixTransformations did.
However, it's hard to discover how to rotate when skimming names of effects, so
it's probably more useful to convey that this effect rotates, than that it
scales to fit.

Otherwise, a lack of HDR decoding support will result in the tests checking output files for HDR output, like HdrEditingTest.transform_noRequestedTranscode_hdr10File_transformsOrThrows, failing.
PiperOrigin-RevId: 510213020
Some of the test methods in `TransformationTest` don't check
capabilities. Add a check just scoped to decoding (not checking
encoding, but the default encoder factory may fall back).
PiperOrigin-RevId: 510088562
It may be confusing for 3P apps, for us to have separate error codes for (1) if
encoding HDR is not supported at all by the device, and (2) if encoding the
format, which happens to be HDR, is not supported by the device. Instead, we can
communicate this in the error message.
PiperOrigin-RevId: 509188666
It doesn't actually make sense for them to be placed in the Transformer, because the error's root causes are actually only in codecs. Also, a few codec errors were
repeated, so deduplicate these instances
PiperOrigin-RevId: 506937695
* Overload added `(cause, errorCode, isVideo, isDecoder, details)`,
where `details` is a string of values to be added to the error message
of the `TransformationException`.
* Overload with `MediaFormat` and `mediaCodecName` moved to
`DefaultCodec`, because all usages of that overload were from
`DefaultCodec`, and this allows a simplified API because of internally
stored values.
* `mediaCodecName` removed from overload that takes a `Format`.
* Reordered `createForCodec` parameters.

Add checks to GL tone-mapping pixel tests, to ensure the device's decoder, API
version, and OpenGL implementation support GL tone-mapping before attempting it.
These tests should be run on mobile harness, to detect per-device failures, and
so are moved to transforemr/mh. Per b/263395272, these tests should ultimately
be in an effect/mh directory.

Also add a Builder to EditedMediaItem to avoid having a constructor with
many optional parameters, or a chain of constructors.
