daeea81e50 Transformer GL: Create demo UI for changing resolution.
Also, add 144p as an acceptable output resolution, to allow for
a more obvious resolution difference when running the demo.

18442b7f0a Fix condition for when to use the FrameEditor.
outputHeight is the actual output height while
transformation.outputHeight could be Format.NO_VALUE
causing the FrameEditor to be used more often than
necessary in the old version.

4af0610067 Shorten log tags to 23 char limit
When calling Android's Log class directly, there's a LongLogTag
lint check that detects tags over the 23 char limit, however it
cannot detect long log tags in ExoPlayer due to the way that we
log via our own Log class. This commit adds @Size annotations to
enforce the same rule.

ed0a53b439 Make FrameEditorTest less flaky
Increase timeout for dequeueing a frame from the codec to reduce flakiness. At a timeout of 2 seconds there was a 2/1000 flake rate and at 3 seconds 0/1000. Set the timeout to 5 seconds to give plenty of leeway.

4dca984aa5 Transformer GL: Apply transformation_matrix to vertex position.
Previously, transformation_matrix was incorrectly applied to
texture sampling coordinates, which led to transformations
seemingly moving in the opposite position, and an undesirable
GL_CLAMP_TO_EDGE behavior when sampling outside the edge of
the texture.

7e82225fa8 Update javadoc to reflect removal of WebM container option

0578b2e4b2 Transformer GL: Create setTransformationMatrix().
Allows a transformation matrix to be input into Transformer,
to apply vertex transformations like cropping, rotation,
and other transformations built into android.graphics.Matrix.

Not building out into a VertexTransformation class yet, as
that class structure wouldn't make sense until we can modify
resolution, per TODOs.

34975a7a89 Increase transformer min API version to 21
This will remove the need to implement compat code handling very old API
versions where some symbols are not available, and it reduces the burden of
dealing with media framework issues around concurrent codec usage that are
worse on older API versions. Top apps that we've surveyed as potential users
for transformer library features are using API 21 or later.

775983c34b Flip input buffer even if the end of stream is reached.
Sometimes the empty end of stream buffer has a non-zero
data limit. Calling flip first, resets the limit to the
position which is zero in these cases.

5694a07ace Add unit test for FrameEditor
The test extracts and decodes the first video frame in the test media, renders it to the frame editor's input surface and then processes data. It then reads back the output from the frame editor, converts it to a bitmap and then compares that with a 'golden' bitmap (which is just the same as the test media's first video frame).

94ef005b17 Rename decoderInputFormat in transformer renderers
- This format is passed to the PassthroughPipeline, which doesn't use
  any decoder.
- In most other cases where it is used, it is not relevant that this
  format will be or has been passed to the decoder. What's relevant is
  that it is the format of the input.

0fbd4959fd Transformer: Move required Builder context to be a constructor arg.
Deprecates setContext() and moves the required Context arg into the constructor.

This way, the parameter can later be final and non-null, per the comment at:
ecb47ba564/depot/google3/third_party/java_src/android_libs/media/libraries/transformer/src/main/java/androidx/media3/transformer/TranscodingTransformer.java (97L)

Also, fixes setOutputMimeType_unsupportedMimeType_throws by providing a context
in the builder, and updating the FrameworkMuxer#supportsOutputMimeType to catch
IllegalArgumentExceptions thrown by FrameworkMuxer#mimeTypeToMuxerOutputFormat.

88d7b14b49 Do not queue empty input buffers.
Follow-up to a comment on 6f0f7dd1be: Buffers that are useful to pass
to the sample/passthrough pipeline should either contain data or the
end of input flag. Otherwise, passing these buffers along is unnecessary
and may even cause the decoder to allocate a new input buffer which is
wasteful.

6f0f7dd1be Adjust timestamp even if frame is dropped.
The `SefSlowMotionVideoSampleTransformer` drops frames by
setting `buffer.data = null` and updates the timestamps of the
frames it keeps. However, these buffers with dropped frames
are still used in the pipeline as they may contain other useful
information, specifically whether the end of the input has been
reached. So, the timestamps should also be updated for the buffers
where frames are dropped.

beccfaba3b Avoid buffers used by OpenGL getting GC'ed
The `GlUtil` wrappers for attributes/uniforms allocate buffers that are passed into OpenGL, and it seems that the distorted output was caused by these buffers being garbage collected.

The issue was difficult to reproduce manually. Add a test that does repeated transcodes in a loop (marked `@Ignore` for now because it runs for a long time and requires network access so may be flaky) to make it easier to run many transcodes and look for inconsistent output. For now the consistency check is just based on the file size which is very likely to change if the actual video frames change.

Verified that the test fails before, and passes once the attributes and uniforms are stored in fields as in this CL.

af1d5856dc Merge transformer video renderers.
This change merges `TransformerMuxingVideoRenderer` and
`TransformerTranscodingVideoRenderer` into `TransformerVideoRenderer`.
Besides all features supported by `TransformerTranscodingVideoRenderer`
the new merged `TransformerVideoRenderer` also supports SEF slow motion
flatting without re-encoding like the `TransformerMuxingVideoRenderer`.
To do this, it uses a `SefSlowMotionVideoSampleTransformer` with
the `PassthroughPipeline`.

18a15fb995 Transformer: Rename setOutputMimeType() to setContainerMimeType().
This mime type is technically for the Muxer, and determines
the container used. In the context of the transformer, this can
be thought of more as a container mime type, to avoid confusion
with the video mime type and audio mime type.

Deprecates setOutputMimeType().

5ae60f2be7 Split VideoSamplePipeline from TransformerTranscodingVideoRenderer.
The `VideoSamplePipeline` handles all steps from decoding to
re-encoding that where previously in
`TransformerTranscodingVideoRenderer`. The renderer is now only
responsible for reading the format, reading input, passing it to the
pipeline and passing the pipeline's output to the muxer.

When no transformations are needed, decoding and re-encoding is
skipped using the `PassthroughPipeline`.
