The encoder surface is no longer needed for the OpenGL setup and frame
processor initialization, as a placeholder surface is used instead. So
all of the setup can now be done in the factory method.

This requires an additional nanos to micros conversion because
the SurfaceTexture uses nanos. But as the timestamps from the
MediaCodec decoder (propagated in DefaultCodec#releaseOutputBuffer) are
in microseconds no precision is lost here.
Also add test that checks output video duration.

MAXIMUM_AVERAGE_PIXEL_ABSOLUTE_DIFFERENCE was copied from a test
class, but BitmapTestUtil isn't a test. So the javadoc needs
rewording to reflect that.

* The AdvancedFrameProcessor calls use() in updateProgramAndDraw().
* The AdvancedFrameProcessor has the same input and output dimensions.

Configuring the frame sizes between frame processors is now the
FrameProcessorChain's rather than the caller's responsibility.
The caller can getOutputSize() and override it for encoder fallback
in configure().
PiperOrigin-RevId: 437048436
The factory method is replaced by a public constructor and
configure() method which configures the input/output surfaces
and handles the OpenGL setup.
This is a prerequisite for removing the responsibility of the
caller to configureSizes() before creating the chain in a follow-up.

This allows us to bypass many device-specific issues, that only occur when
decoding directly to an encoder surface, without OpenGL. This also allows us
to maintain fewer code branches, which require additional testing to verify
correctness.
PiperOrigin-RevId: 437003138
Allow apps to modify how frames are presented, via modifying resolution.
A follow-up CL will provide aspect ratio, cropping, etc.
PiperOrigin-RevId: 436963312
SEF is similar to frame editing, where the input and output videos are
not intended to match, so SSIM will not provide a reliable value. To
check SSIM correctly in future, we would need to provide
golden/expected video files to compare output against.

The FrameProcessorChain manages a List<GlFrameProcessor>.
FrameProcessorChainDataProcessingTest now tests chaining ScaleToFit-

This currently causes the test to fail on Pixel 6 Pro running a recent S build
SQ1D.220205.004.
There is no need to test audio transcoding while we are measuring video
quality.
PiperOrigin-RevId: 435635314
ExternalCopyFrameProcessor's output dimensions match the input
size not the output size. So the intermediate texture size
should match the input size.
Also rename configureOutputDimensions to configureOutputSize.
PiperOrigin-RevId: 435058789
Use android.util.Size, whose naming is much easier to understand than Pair<Integer, Integer>, in both FrameProcessor and EncoderUtil.

* Move auto-adjustments for transformation matrices from the
VideoTranscodingSamplePipeline constructor to the new
ScaleToFitFrameProcessor.
* Add GlFrameProcessor#getOutputDimensions() to allow for GlFrameProcessors with
different input and output dimensions. This is a prerequisite for
Presentation.
* Tested with unit tests (and manually just in case).
* A follow up CL will implement change the FrameProcessor input to be scale and
rotate values as requested by the user. This was kept out of this CL to
reduce CL review size. Presentation will also be implemented in a follow up
CL.

If an OpenGL call blocks because the encoder's input surface is full,
this will now block the background thread while the main thread can
continue querying encoder output and free up encoder capacity until
it accepts more input unblocking the background thread.
PiperOrigin-RevId: 433283287
This will allow for easier customisation of the additional tasks
performed by the test runner, such as calculating metrics like SSIM.
PiperOrigin-RevId: 432434850
This test tests the same cases as the FrameEditorDataProcessingTest
as currently the main FrameEditor functionality is to apply a
transformation matrix using a TransformationFrameProcessor.

We use SSIM to measure the transcoding quality between. SSIM is a widely used
tool that compares the luma channel between two images, and generates a score
from 0 to 1 that indicates "how similar" the two images are.
In `SsimHelper`, we decode the two videos, extract matching frames and
calculates the mean SSIM (SSIM averaged all matching frames) for both videos.
Matching frames are referred to as "comparisonFrame" in the CL, which is
selected based on the frame number and a user-set comparison interval.
For instance, if the interval is 7, then every seventh frames are compared.
We use MediaCodec/MediaExtractor to decode the video, and use ImageReader to
extract the decoded frame.
The SSIM calculation logic is a inspired by and modified from the CTS
[MSSIMMatcher](https://cs.android.com/android/platform/superproject/+/master:cts/tests/tests/uirendering/src/android/uirendering/cts/bitmapcomparers/MSSIMComparer.java;l=1?q=mssimcom)
that has some errors and extra features we don't need (like handling RGB
images).
Adds TranscodeQualityTest to ensure high quality transcoding.

All (later customizable) GlFrameProcessors after the
ExternalCopyFrameProcessor receive their input from a normal OpenGL
texture not an external texture, so they won't need to worry about
the textureTransformMatrix.

There are two major blockers to this test:
- H265 muxing is not available for API<24, so setting video mimeType to H265
will fail on those devices.
- AMR audio encoding is buggy on some device and it's not a widely used format.
The solution: use a video that is encoded with AVC/MP3, to ensure transcoding
to AVC/AAC.

Fallback is only disabled for robolectric and instrumentation tests.
For MH tests, fallback is not disabled, as it may be needed due to
the broad range of devices available.

- Add a checkbox in the demo app to enable experimental HDR editing.
- Add an `experimental_` method to `TransformationRequest` to enable HDR editing.
- Add fragment/vertex shaders for the experimental HDR pipeline. The main difference compared to the existing shaders is that we sample from the decoder in YUV rather than RGB (because the YUV -> RGB conversion in the graphics driver is not precisely defined, so we need to do this to get consistent results), which requires the use of ES 3, and then do a crude YUV -> RGB conversion in the shader (ignoring the input color primaries for now).
- When HDR editing is enabled, we force using `FrameEditor` (no passthrough) to avoid the need to select another edit operation, and use the new shaders. The `EGLContext` and `EGLSurface` also need to be set up differently for this path.

TransformerTest sounds like a unit test for Transformer but these
tests test behaviour that involves multiple stages of the pipeline.
PiperOrigin-RevId: 425378369
If
a) the end of stream buffer arrives with a frame rather than an
empty buffer or
b) processDataV29() renders several decoder output buffers to the
FrameEditor's input Surface immediately before encountering the
EOS flag
these frames were previously stuck in the FrameEditor's input Surface
and never fed to the encoder.
PiperOrigin-RevId: 424898820
This test tests that all frames are processed when transcoding
video to a different sample MIME type (and that the transformation
completes successfully).

Expected images are taken on emulators, so a larger acceptable
difference from expected images must be accepted on physical devices.

Being able to see the output of the GL pipeline is useful for debugging. For
example, when we previously saw flakiness it would have been useful to be able
to tell quickly whether the output looked wrong without needing to run a
transformation to the end then inspect the output file, and when working on
support for HDR editing it's useful to be able to do manual testing on devices
that don't support HDR encoding (but do support decoding/processing it with
GL).
Also change the progress indicator to be linear as this looks better in the
demo app when shown next to the debug preview.
PiperOrigin-RevId: 414999491
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.

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.

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).
PiperOrigin-RevId: 413131811
We need the filename of the output videos to be predictable, because
MobileHarness requires the exact filename to pull the file.

The features supported by `TranscodingTransformer` are a

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.
