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

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.

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.

(cherry picked from commit 931562c2)

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.

(cherry picked from commit fdfca880)

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.

(cherry picked from commit d6a6b447)

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 a105d033)

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.

SingleFrameGlTextureProcessor is now an abstract class containing a
default implementation of the more flexible GlTextureProcessor interface
while still exposing the same simple abstract methods for single frame
processing it previously did.

FrameProcessorChain and GlEffect will be changed to use
GlTextureProcessor in follow-ups.

This change makes MediaSessionPermissionTest.removeMediaItems()
non-flaky. This is a quick fix though it'd be good to refactor this
test file.

PiperOrigin-RevId: 453162764
(cherry picked from commit 34ca3bc3)

Implementations of this interface will be able to drop or add frames,
change timestamps, accept multiple input frames before producing
output, and process frames on their own background thread.

A default implementation of this interface will be added to SingleFrameGlTextureProcessor in a follow-up.

PiperOrigin-RevId: 453159835
(cherry picked from commit 63436390)

This internal listener avoids wrapping the TransformationExceptions
in PlaybackExceptions that are handled via the Player.Listener and
is also used for FrameProcessingExceptions which already avoided
the PlaybackException layer previously.

This listener will also be useful in follow-ups for encoder-related
TransformationExceptions that are thrown in the SurfaceProvider that
will be called on the GL thread.

(cherry picked from commit 35b5147e)

Once the more advanced GlTextureProcessor interface exists,
it will be possible to change the output size of a GlTextureProcessor
between frames. To keep the re-configuration based on the frame sizes
minimal, things indepedent of the frame size, such as the GlProgram,
can be initialized in the constructor.
