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
PiperOrigin-RevId: 422513738
The app will be notified about fallback using a callback on
Transformer.Listener. Fallback may be applied separately for
the audio and video options, so an intermediate internal
FallbackListener is needed to accumulate and merge the track-specific
changes to the TransformationRequest.

Simplifying and clarifying variables, and adding comments.
Tested by confirming demo-gl and demo-transformer both
correctly display videos

After this change exceptions throw by MediaCodec during
encoding/decoding will result in TransformationExceptions with
ERROR_CODE_ENCODING_FAILED/ERROR_CODE_DECODING_FAILED.
Before this change ERROR_CODE_FAILED_RUNTIME_CHECK was used.

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

Codec and its factories can use MediaCodec directly as for API >= 21,
the SynchronousMediaCodecAdapter methods used in Codec just correspond
to a single MediaCodec call each so there is no reason to have another
wrapping layer.
PiperOrigin-RevId: 421041177
Exceptions thrown by MediaMuxer are converted MuxerExceptions
and later to TransformationExceptions with ERROR_CODE_MUXING_FAILED.
PiperOrigin-RevId: 421033721
The encoder and sonic are now set up in the constructor rather
than in a configuration method called from processData(). This
is more similar to VideoSamplePipeline and reduces null checks.
PiperOrigin-RevId: 420260526
Only allowing TransformationExceptions to be created using the factory methods helps keeping error messages consistent. This is consistent with ExoPlaybackException.
PiperOrigin-RevId: 419841025
Compensate for aspect ratio of input frames, so that they're applied on
rectangular frames instead of square normalized-device-coordinate frames.
This fixes distortion most visible when rotating any GL video 45°
(non-rectangular frames) or 90° (stretched frames)
Tested by rotating several landscape/portrait demo videos.
(Automated tests will follow in <unknown commit>)

* Move checking that the output format is supported by the muxer
from supportsFormat (which deals with the input format) to
ensureConfigured.
* Add maps for the supported MIME types so that the muxer can
return what MIME types it supports rather than just check a
MIME type.
PiperOrigin-RevId: 419578165
This is better than silently dropping tracks as done previously. Later,
we will implement fallback to transcoding to a supported MIME type.
PiperOrigin-RevId: 418006258
This more closely matches the pattern we have for all implementations
except DefaultMediaSourceFactory (e.g. ProgressiveMediaSource.Factory)
and other factory interfaces like (Http)DataSource.Factory.
PiperOrigin-RevId: 417826803
Switch to using sentence-case naming convention but with one character prefixes for different types.
This is a no-op change.
PiperOrigin-RevId: 417791624
Move static factories into a separate class and make it implement an interface
that will let tests customize encoder/decoder creation.
PiperOrigin-RevId: 417610825
Transformer uses ExoPlayer for reading input. Apps using Transformer
do not need to know this. So, PlaybackExceptions are converted to
TransformationExceptions with the same message, cause and error code.
The corresponding IO error codes are copied from PlaybackException.
