We have seen devices running on API21/23 fail transcoding because of setting
encoding profile/level.
Some devices (ale-123/nexus 7) on API21 returns ENOSYS (Function not
implemented) when being configured with a profile setting. (although API21
introduced the capability of setting encoding profile)
Some devices (nexus 5) on API23 fails configuration with a specific parameter
set, despite advertising support for it.
Not setting the baseline profile has no effect on encoding, because when not
set, the encoding will pick a suitable profile to use. Since baseline is
the lowest possible profile, the auto-picked value can't be worse than
baseline.

On some Android devices, the return value of
```
MediaCodecInfo.getCapabilitiesForType(mimeType).profileLevels
```
contains one entry for each encoding profile, like <profile, maxSupportedLevel>
but on some other devices, there are multiple entries for the same profile,
like <HIGH_PROFILE, LEVEL1>, <HIGH_PROFILE, LEVEL2>, <HIGH_PROFILE, LEVEL3>,
where we need to iterate through all the entries and find the max.

On some old devices, the encoding level needs to be set with the encoding
profile, but not on newer devices.
The profile/level override is applied by following

This is a breaking change if the annotation itself is in use in Kotlin
code. It's judged that the IntDefs in this commit are unlikely to be
referred to often in Kotlin code. This is because they're either:
- Related to esoteric parts of the library, or
- In a common part of the library but only returned from methods (and
never passed to callback methods).
A follow-up change will fix the positions of existing usages to match
this new config.

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.

Reason for not rolling back the rollback 9151103968: file name changed and
file content moved, the automated tool is unable to correctly apply the change.
Apply suggested AVC profile depending on the API version.
Use `AVCProfileHigh` only when there's encoder support.

This change makes GlUtil.Program an outer class named GlProgram,
and also moves private static helpers as well as the inner classes
Attribute and Uniform which were only used by GlUtil.Program to
GlProgram. Other static utility methods remain in GlUtil.
No functional changes intended.

The longer list of targets is only necessary for backwards
compatibility with existing Kotlin code that will stop compiling
if the position of the annotation becomes 'wrong' by marking it only
TYPE_USE. Since none of these IntDefs have been released (except in
media3 alpha1) we don't need to maintain this compatibility.
Also add a comment to all the places that *do* need the longer list of
targets, in order to explain why it's there and discourage copy-pasting
when defining new IntDefs in future.
Also fix some single-element arrays to remove the array notation.

- The MIME type should ideally default to HEVC if there is an encoder for it.
- Next, check if AVC is supported.
- If there is no encoder for AVC, then we should pick an encoder in the list of
existing encoders instead of abandoning the transformation.

Tested by confirming transformations still work and write to a output file in a
scoped-storage directory on a:

* Google Pixel 4 API 31 physical device

- 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.

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).

If muxerWrapper.release() was throwing an exception, the progress state
was not updated and getProgress could throw an exception.

When the decoder output buffer was partially read, a call to
Codec.getOutputBuffer() was returning the same buffer, but with the
position reset to 0. The reason was that, in
Codec.maybeDequeueAndSetOutputBuffer(), mediaCodec.getOutputBuffer()
was called with the same buffer index (L350 in old rev), even though
there was already a buffer available (outputBufferIndex >=0). This
change avoids calling mediaCodec.getOutputBuffer() if the previous
buffer has not been released.

If the encoder picks a fallback resolution the video pipeline needs
to take this into account when configuring the frameEditor and when
setting up the fallback TransformationRequest that's passed to the
fallbackListener.
PiperOrigin-RevId: 424611290
If the output sample MIME type is inferred from the input
but is not supported by the muxer, we fallback to transcoding
to a supported sample MIME type.
The audio and video renderers need to make sure not to select the PassthroughSamplePipeline for this case. Which sample MIME type
to choose is decided by the EncoderFactory.
PiperOrigin-RevId: 423272812
We may fall back to a different sample MIME type because
a) the sample MIME type inferred from the input is not supported
by the muxer or b) no encoders are available for the the requested
sample MIME type.
PiperOrigin-RevId: 422849036
TransformationRequest is otherwise immutable, so if we modify the
transformationMatrix in place (done before this cl) this may cause
confusing behaviour for apps when they reuse a TransformationRequest.
PiperOrigin-RevId: 422822916
After implementing fallback, it won't always be possible to
differentiate between muxer and encoder as the cause of an output
format not being supported.
PiperOrigin-RevId: 422780443
This CL implements fixing the input format to the encoder spec. Fixed
parameters include:
- MIME type
- Profile & level
- Resolution
- frame rate, and
- bitrate
