In `ExternalTextureManager` in seemingly rare cases end of stream is signaled
at the point where a frame is currently pending processing. In that case the
video end of stream signal was lost. If the muxer timeout was enabled this
case would result in throwing an exception, but otherwise the operation would
get stuck
Add code to signal end of stream in `onInputFrameProcessed` as well, so that we
signal end of stream when the pending frame is handled.
Tested by running
`TransformerEndToEndTest.loopingTranscodedVideo_producesExpectedResult` several
times.

In addition to the changes in 3a5c4277a7
This change essentially reverts 30e5bc9837 (Merged Jul 2022).
From this CL on, `VideoFrameProcessor` takes in non-offset, monotonically
increasing timestamps. For example, with one 5s and one 10s video,
- `VideoFrameProcessor`'s input should start from 0
- On switching to the second video (10s), the timestamp of the first frame in
the second video should be at 5s.
In ExoPlayer however, `streamOffset` is managed differently and thus needs
correction before sending the frames to `VideoFrameProcessor`:
- The timestamp of the first video is offset by a large int, so the first frame
of the first media item has timestamp (assuming) 10000000000000000
- The last frame of the first media item has 10000005000000000
- At this point the stream off set is updated to 10000005000000000
- The pts of the first frame of the second video starts from 0 again.

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.

NPE in toneMap_hlgFrame_matchesGoldenFile and toneMap_pqFrame_matchesGoldenFile was created because a uEnableColorTransfer uniform was being created on the HDR path, when HDR shader files don't have this uniform. (they don't support disable color transfers right now)
Fix: only create the uniform when input is SDR.
manually tested on failing tests

By having a single base class for GL shader programs we simplify the customization
of new shader programs. The concrete cases include
- Allow frame dropping in shader program
- Creating a FrameCache that selectively (based on timestamp) replays and clears
the cached content

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.

Since the composite matrix is ultimately rewritten to, we need to ensure it's cleared (to identity) before update.
Test plan: use an effect as a time based approach and see that the effect no longer clips
PiperOrigin-RevId: 518886623
Reduce nesting by using an early return. Also, rename
`outputSizeOrRotationChanged` to `outputChanged`, because this also applies to when the output surface changes.
Also, update local variable initialization, add some javadoc, and remove unneeded
local variable

d288891c77 added clearing depth buffers to GLUtil, so there is no need to have allow apps to have a custom clearOutputFrame.
Also removes default implementations in GLObjectsProvider know that these methods have been implemented.

Instead of using a long frameDurationUs with Math.floor, use a double
frameDurationUs with Math.round,
Before, playing an image with 30 fps over 1 second would result in the final
timestamp not being aligned to the expected 1 second timestamp. Over long
periods of time, this can lead to significant timestamp drift. Additionally,
for TimestampWrapper and constrained multi-asset, where TimestampWrapper
begins the 2nd effect on the 2nd asset's startTimeUs, this floor() behavior
can lead to the first few frames of the 2nd asset using the first asset's
effects, due to timestamps being mismatched.

By making this method accept context, we can use DefaultDataSource.Factory in the DatasourceBitmapLoader to support a wider range on URI schemes in Bitmap Overlays. (and implement a local file picker for images for custom bitmap overlays in the demo transformer app)

To create this file TextureInfo has been moved to common and renamed to GLTextureInfo.
We'll look to expand the interface in future to cover more of the methods around GL object maintenance in future as required.
PiperOrigin-RevId: 514445397
Before, we used to never call glDeleteFramebuffers, which could
in theory lead to leaks in the number of frame buffers
available and make releasing the GL context more expensive.

Used an actual captured image with set color profile for test to minimise the chance of the test flaking. Also renamed the media/bitmap/overlay folder to media/bitmap/input_images for clarity.

Based on 1000 test runs an emulator, with the current timeout releasing
fails (even with no custom effects) about one percent of the time.
Releasing normally completes in about 30 ms but occasionally
`eglTerminate` took up to 200 ms (and even releasing an effect
took up to 80 ms in one case).
With the new timeout of 500 ms, we still catch stuck effects reasonably
quickly but the number of flaky test failures should be less than one in
ten thousand.

Uses the first mediaItem's format as the output format.
If there is `Presentation` supplied in the `Composition.effects`, add it as the
last effect of the first EditedMediaItem.
PiperOrigin-RevId: 512082659
Also remove @WorkerThread annotations, as static checks associated with
this annotation aren't useful in this part of the codebase because
almost no methods are called on the main thread.
This change should be a no-op.
PiperOrigin-RevId: 512060367
Currently if releasing a shader program throws we don't release the GL
context, which could leak resources, and any errors are silently dropped
as we suppress notifications during releasing.
Improve resource cleanup and debuggability of errors from custom effects
by continuing to release shaders on failure (for runtime and
`VideoFrameProcessingException`s) and always clean up the GL context.
Note: this doesn't help with the case where releasing a custom shader
blocks for a long time, causing releasing the frame processor to
time out.
PiperOrigin-RevId: 512042501
Also, allow isNoOp to default to false without the TODO, so that implementations
of isNoOp must opt-in to implementing the override in order to be considered for
skipping the effect (ex. for transcoding in Transformer).

Rename:
* MatrixShaderProgram to DefaultShaderProgram, and
* FinalMatrixShaderProgramWrapper to FinalShaderProgramWrapper.
PiperOrigin-RevId: 510498547
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.
PiperOrigin-RevId: 510480078
Now that the GLEffectFrameProcessor handles external (video) and internal (image) input, components used only for external input needs should be moved to the ExternalTextureManager for code clarity
