If the input is HDR (HLG), check encoder capabilities for HDR support
and request tone-mapping to SDR during decoder configuration otherwise.
Capabilities are only checked for API 31 and above, as HDR editing is
not supported before.

As the encoder capabilities check needs to happen before selecting the
encoder to use (as this may depend on the resolution output by the
effects chain), the EncoderWrapper checks all candidate encoders
for the MIME type for HDR capabilities and only requests fallback to
SDR if none of them support it.

When the actual encoder is selected, the wrapper checks that it matches
one of the encoders is checked capabilities for.

Configure the GL shaders and encoder to take in HDR metadata.

This mostly just consists of passing the Format.colorInfo through
the VideoTranscodingSamplePipeline down to the encoder, rather than passing
the PQ-ness down to the GL step.

Due to b/237674316, this will remove HDR10+ support temporarily to introduce
support for HLG10.

Manually tested to confirm that HLG10 operations that don't affect color display
correctly after this CL with "HDR editing" in the demo checked, and continue to display incorrectly (as before this CL) without the option unchecked.

The old getString() will throw because FRAME_RATE can only be float or int.

We used "ALL_COOECS" previously, and it is not necessary because "ALL_CODECS"
additionally the codecs that support tunneling/secure decoding, which there
is no use case in Transformer.

Although MediaCodec claims supporting float frame rate, encoder init failed on
API21 Nexus 5. Since it's just a performance hint to the codec, it's OK to
generalize it to other API versions.

- Improve variable naming to include time units for clarity
- Fix existing timestamp calculations to respect time units as well as track tempo (default values for now)
- Ensure the synthesizer produces PCM for the correct amount of time (including gaps between commands).

The GlEffectsFrameProcessor that will be part of the effects module
uses the DebugViewProvider. So it does not make sense for it
to be an inner interface of Transformer.

The FinalMatrixTransformationProcessorWrapper ensures that the
surface is only replaced when it is not being rendered to and vice
versa.

The outputHeight in the TransformationRequest is the height of
the frame as it would be displayed (i.e., after applying any
rotation specified in the format). So pass-through should only
be used if the requested outputHeight matches the input
format's height after applying the rotation.

pixelWidthHeightRatio is now passed to setInputFrameInfo instead of
the factory.

This will be useful for downgrading to a lower resolution during
a slow preview and for processing slide-shows once sequential
multi-asset editing is supported.

videoEncoderFormatUnsupported_completesWithError() has recently
been flaky on API 31 emulators on presubmit because a different
exception than the expected exception is thrown.
This disables it on those emulators to reduce testing noise
until the underlying problem is investigated and resolved.

This change is just renaming. There is no functional change intended.
The FrameProcessor interface will be created in a follow-up.

`TextRenderer` is updated to output `CueGroup`, which contains the presentation time of the cues, in microseconds.

After this change GlEffects can use any GlTextureProcessor not just
SingleFrameGlTextureProcessor.
MediaPipeProcessor now implements GlTextureProcessor directly which
allows it to reuse MediaPipe's output texture for its output texture
and avoids an extra copy shader step.

(cherry picked from commit e25bf811)

After this change, FrameProcessorChain chains any GlTextureProcessors
instead of only SingleFrameGlTextureProcessors.

The GlTextureProcessors are chained in a bidirectional manner using
ChainingGlTextureProcessorListener to feed input and output related
events forward and release events backwards.

This is useful for testing Transformer in the same way as it is used
in tests and to see only the real transformation time.

In follow-ups the FrameProcessorChain will set an instance of this
listener for each GlTextureProcessor to chain it with its previous
and next GlTextureProcesssor.

The wrapper
* catches exceptions for each task and notifies the
  listener (this will be used more in follow-ups when processFrame
  is split into lots of listeners and callbacks),
* removes finished tasks from the queue and signals any exceptions
  that occurred to the listener each time a new task is executed.

PiperOrigin-RevId: 455114693
(cherry picked from commit 10050a1e)

This change adds a SurfaceProvider interface which is necessary to
allow for texture processors whose output size becomes available
asynchronously in follow-ups.
VTSP's implementation of this interface wraps the encoder and provides
its input surface together with the output frame width, height, and
orientation as used for encoder configuration.
The FrameProcessorChain converts the output frames to the provided
orientation and resolution using a ScaleToFitTransformation and
Presentation replacing EncoderCompatibilityTransformation.

- Fixed MidiExtractor state issues which caused seeking to behave unexpectedly. Ensures the extractor is now always in the file loading state after returning RESULT_END_OF_INPUT.
- Fixed an infinite loop in MidiExtractor caused by the file data array having an initial size of 0. The extractor attempted to increase the capacity of the array by using this size of 0 in it's calculations.

The native GL errors are in an arbitrary order according to
https://www.khronos.org/registry/OpenGL-Refpages/es2.0/xhtml/glGetError.xml
This means any of them could contain the most useful message
so it's better to use all for the GlException's message rather than
picking the last message and logging all others.

Based on
https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface,
frame dropping behaviour depends on the target SDK version.
After this change transformer will only use
MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK
version are at least 29 and default to its pre 29 behaviour where each
decoder output frame must be processed before a new one is rendered
to prevent frame dropping otherwise.

Also remove deprecated Transformer.Builder constructor without a
context and the context setter.

PiperOrigin-RevId: 453971097
(cherry picked from commit 3f718b0d)

Transformer always enabled glAssertionsEnabled, so there should
be no functional change.

ExoPlayer previously disabled glAssertionsEnabled, so GlUtil logged
GlExceptions instead of throwing them. The GlExceptions are now
caught and logged by the callers so that there should also be no
functional change overall.

This change also replaces EGLSurfaceTexture#GlException with
GlUtil#GlException.

This removes the prior restriction of needing to remember not to crop and set aspect ratio in the same Presentation.Builder, and makes each class a bit more targeted.

This is partially made feasible by the past work to merge consecutive
MatrixTransformations into a single MatrixTransformationFrameProcessor, which
ensures that there's no loss in quality between successive MatrixTransformations.
