- 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.

We need the filename of the output videos to be predictable, because
MobileHarness requires the exact filename to pull the file.

Fixes the gradle compilation failures.
Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.

This change moves methods that are the same in
`TransformerAudioRenderer` and `TransformerVideoRenderer` to
`TransformerBaseRenderer`.

Document that apps should retain `GlUtil.Program` while the program is in use,
and keep a reference to attributes/uniforms within the program to make sure
they don't get GC'd causing any allocated buffers passed to GL to become
invalid.
Tested manually by running gldemo and transformer.

The features supported by `TranscodingTransformer` are a
superset of those supported by `Transformer` after merging
the video renderers in <unknown commit>. This change removes
`TranscodingTransformer` and adds its features to `Transformer`.

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.

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.

In the near future, we will be able to specify which tests run on this
target explicitly, at which point this ignore will be removed.

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.

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`.

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().

Simple, initial implementation to allow setResolution()
to set the output height, for downscaling/upscaling.
Per TODOs, follow-up CLs may change layering, add UI,
or allow querying decoders for more resolution options.

The decoder writes to `OpenGlFrameEditor`'s input `Surface`
and the `OpenGlFrameEditor` writes to the encoder's input `Surface`.

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`.

When dropping the remainder, the decoder and encoder timestamps start diverging after a few buffers when no speed changes are supposed to occur. Tracking the remainder keeps them in sync.

* Remove GlUtil.Program String[] constructor to unify and just use the
String constructor.
* Add getAttributeArrayLocationAndEnable() to simplify things a tiny bit.
* Increase usage of constant values.

`TransformerAudioRenderer` reads input and passes `DecoderInputBuffer`s to the `AudioSamplePipeline`. The `AudioSamplePipeline` handles all steps from decoding to encoding. `TransformerAudioRenderer` receives `DecoderInputBuffer`s from the `AudioSamplePipeline` and passes their data to the muxer.
`AudioSamplePipeline` implements a new interface `SamplePipeline`. A pass-through pipeline will be added in a future cl.

If the number of samples changes, the sizes will help us to verify whether they are just split differently or extra data was added.

This helps to prevent issues where decoders can't handle negative
timestamps. In particular it avoids issues when the media accidentally
or intentionally starts with small negative timestamps. But it also
helps to prevent other renderer resets at a later point, for example
if a live stream with a large start offset is enqueued in the playlist.

`checkNotNull` should be avoided where possible.
This change adds `@EnsuresNonNull` or `@EnsuresNonNullIf` to configuration methods for fields they initialize.
`checkNotNull` is now avoided for the `@MonotonicNonNull` formats by adding `@RequiresNonNull` annotations.
`checkNotNull` is now avoided for the encoder and decoder in `feedMuxerFromEncoder()`, `feedEncoderFromDecoder()`, `feedDecoderFromInput()`, etc. by creating local variables for `encoder` and `decoder` in `render` after the configuration method calls and passing these as non-null parameters.

Also check that the output video MIME type is supported with the given container MIME type in `TranscodingTransformer` and `TransformerBaseRenderer`.
PiperOrigin-RevId: 405645362
When no encoder video MIME type is specified, the `TransformerTranscodingVideoRenderer` now uses the video MIME type of the input for the encoder format.
The input format is now read in a new method `ensureInputFormatRead` which is called before the other configuration methods. This removes the logic for reading the input format from `ensureDecoderConfigured`, because it is now needed for both encoder and decoder configuration but the encoder needs to be configured before GL and GL needs to be configured before the decoder, so the decoder can't read the format.
The width and height are now inferred from the input and the frame rate and bit rate are still hard-coded but set by the `MediaCodecAdapterWrapper` instead of `TranscodingTransformer`.
PiperOrigin-RevId: 405631263
This introduces a new option `setAudioMimeType` in `TranscodingTransformer.Builder` and a corresponding check whether the selected type is supported. This check is done using `supportsSampleMimeType` which is now part of the `Muxer.Factory` and `MuxerWrapper` rather than `Muxer`.
A new field `audioMimeType` is added to `Transformation` and the `TransformerAudioRenderer` uses this instead of the input MIME type if requested.
