This test should run on all devices from API 21 (the media uses Baseline
profile level 3.0 H.264) to give us coverage of the full pipeline (forcing
re-encoding) and SSIM calculation on all devices.

Some devices under report their resolution support, like 2144 for 2160 in
H265, 1072 for 1080 in H264. This CL only takes care of these two cases,
- reporting 1920x1080 is supported when the device reports 1920x1072, and
- reporting 3840x2160 is supported when the device reports 3840x2144

* Group what's now many related test PNGs by moving them to their own directory.
* Move bitmap references to files where they're used, as each bitmap is only
used once each, except the original bitmap.

What a minimal implementation should include is now explained in the
interface javadoc while the method name reflects what the method does.

The stream with the mp3 track is added because
- We only encode to AAC
- We only encode when the source track is not AAC
Now that we have a way to force encoding, we no longer need the mp3 track.
The test asset is kept for later parameterized testing.

The MIME type was set to H265 to force transcoding. Now that we have an encoder
factory that forces encoding, switching back to H264 ensures the quality test
is conducted on more devices (those don't support H265 can be tested now).
However, H265 should be part of the quality test after we have proper mechanism
to skip test based on device capability.

We don't currently have enough understanding of the correlation between a
specific SSIM score and video quality. Dropping to .90 to make most tests pass.
Especially when there's no discernible difference from the videos with .9 and
.95 SSIM.

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.
PiperOrigin-RevId: 437028882
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.

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.
PiperOrigin-RevId: 436707240
The FrameProcessorChain manages a List<GlFrameProcessor>.
FrameProcessorChainDataProcessingTest now tests chaining ScaleToFit-
and AdvancedFrameProcessors.

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.
