AudioMixingUtil#mix handles input & output in float or Int16 PCM. Given
Float and Int16 use different sample ratnes, this util handles
conversion between the two, based on the encoding being mixed to.
Migrate AudioMixer to use the util, removing AudioMixingAlgorithm
interface and implementation. ChannelMixingAudioProcessor will be
migrated after additional performance checks.

This serves as a sort of test with more frames for the compositor for now
(before more varied video system tests come later when integrating with
Transformer), showing it doesn't error out and outputs the right
amount of frames.
Due to the VFPTestRunner having a 5s timeout, and mostly due to presubmit
emulators being very slow with OpenGL, there is a sort of limitation
to how many frames this type of test can have, depending on the test target

Frame buffers are focused, not current. EGL Contexts may be current but this

On a MediaItem change, the input Format (and Effects to apply) may be
different. Therefore the AudioProcessingPipeline must be reconfigured
to determine what processing is active, and what the AudioFormat of the

be able to accept the audio buffers.

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

Issue: When running the Transformer related test cases, the tests are flaky
because the order in which audio and video samples are interleaved seems to
differ in few instances.
Root cause: When running a transformation the sample producer (Asset loader)
and sample consumer (Sample pipeline) both runs on different thread and
theoretically there is no reason for behaviour to be deterministic because
the number of samples produced/written depends on how fast individual thread
works. So it is indeed surprising that test somehow worked deterministically in
majority of instances (may be something to do with Robolectric environment).
Solution: Since we don't expect the order of sample interleaving to be deterministic, make the dumping logic deterministic where all the video
samples will be collected and then dumped together (similarly for audio). This would mean we won't be able to see the interleaving so for that we need to
add separate test case verifying the interleaving logic only.
Pending: Test case for interleaving.

Tone-mapping an HDR video with MediaCodec on sm-s908u1 was timing out.

In ASwB, all Transformer tests can be run by right-clicking on the project and

files within a project (ex. all non-analysis tests) to run tests on.
Add @Ignore to analysis tests, which are not intended to be run anyways
when determining whether Transformer is working on some device. These
tests also don't have proper skipping logic when a device doesn't support a

This eases manual testing, for example when debugging whether tests all pass
on a device.
When analysis tests are desired to be run, it should be easy to comment out

Simplify the audio encoder input timestamp calculation. The new calculation
avoids drifting by tracking the total number of bytes encoded rather than
tracking the timestamp and remainder separately, and also makes the timestamps
match the decoder output buffer timestamps.
Also switch one of the export tests that was passing through AMR samples over
to using WAVE audio. The problem with using AMR is that the compressed samples
are not necessarily an integer number of audio frames and the shadow decoder
would pass them from input to output, so the audio encoder was receiving
non-integer numbers of audio frames.
Tested by logging the timestamps at the decoder output and encoder input with
forcing transcoding audio, and verifying that after this change the audio
timestamps are no longer off by one.

The video asset loader renders decoder output to a surface texture, and if the

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.
PiperOrigin-RevId: 522362101
Handling of the stream offset and start position was unnecessarily
complex and even incorrect. It was going to be an issue for
concatenation of video and image input.
The stream offset is the offset added before decoding/encoding to
make sure it doesn’t fail in case of negative timestamps (which do
rarely occur).
The start position is equal to the stream offset, plus the clipping
start time if the media is clipped.
Before this change:
- Samples were offset by the start position before decoding, and this
offset was removed before muxing.
- The startPosition of the first MediaItem in a sequence was used for
all the MediaItems in this sequence (which is incorrect).
- The stream offset was removed before applying the GL effects and
added back before encoding so that it was not visible to the OpenGL
processing.
After this change:
- The start position is subtracted in the AssetLoader, so that the
downstream components don’t have to deal with the stream offsets and
start positions.
- Decoded samples with negative timestamps are not passed to the
SamplePipelines. The MediaMuxer doesn’t handle negative timestamps
well. If a stream is 10 secondes long and starts at timestamp -2
seconds, the output will only contain the samples corresponding to the
first 8 (10 - 2) seconds. It won’t contain the last 2 seconds of the
stream. It seems acceptable to remove the first 2 seconds instead.

- This is to make sure we know about all the tracks before initializing

which the tracks are written has changed.
- The ImageAssetLoader also had to be updated to call onOutputFormat

If the Metadata passed to SegmentSpeedProvider is null, then the
SegmentSpeedProvider will always return 1f from getSpeed.
Initializing a SpeedChangingAudioProcessor requires a SpeedProvider.
Once configured,this audioProcessor is always active, so buffers are
passed through it. Because getSpeed is always 1, the processor performs
a no-op, but still has to do a buffer copy for each buffer.
By not initializing the audio processor when metadata is null, this
copy can be skipped and the audio pipeline is more performant.
Note: This change does not affect the multiple media-item case, which
is not supported with speed changes, as per Transformer API
documentation.

so fix the format (and associated errors). This also allows us to remove the
exception catch in ForceInterpretHdrVideoAsSdrTest, which was included due to
errors from the incorrect format.

- Split the transmux setting into transmuxAudio and transmuxVideo. This
is more flexible for apps and will also be useful for unit testing
(particularly as we can't test video transcoding on Robolectric at the
moment).
- Move these settings to Composition. It makes sense for these settings
to be next to forceAudioTrack. Apps may also want to set these
settings based on the current Composition's MediaItems.
- Add a Composition.Builder because Composition now contains a few
optional fields.

Implement getMediaFormatInteger, a helper method simulating mediaformat.getInteger(name, defaultValue).
This reduces the API 29 restriction from MediaFormatUtil.getColorInfo to API 24, in
particular removing the method-based restriction to a constant-based restriction,
so that we can reduce usage of the API 29 class.
This also allows us to slightly simplify prior use-cases where we'd check
containsKey and getInteger to have a default value.

When clipping a MediaItem with start time > 0, the audio was ending
before the video. This is because:
- Audio timestamps are computed based on the sample sizes, with a start
time set to streamOffsetUs (i.e. the streamStartPositionUs is not
taken into account).
- The SamplePipeline was subtracting streamStartPositionUs from the
timestamps before sending the samples to the muxer.
- As a result, the audio timestamps were shifted by
streamStartPositionUs, while they should be shifter by streamOffsetUs.

* Account for `AssetLoader` output types.
* Consider cases that are not audio/video specific.
* Use `Format#sampleMimeType` for track specific conditions to check.
* Untangle `SamplePipeline` initilization from `AssetLoader` state.

- Add silent audio when the output contains an audio track but the
current MediaItem doesn't have any audio.
- Add an audio track when generateSilentAudio is set to true.

Previously, this was limited to API 29. Expand this to all API versions.
Also, update the test to:
(1) skip based on SDR format input instead of HDR format input
(2) Check the exception message in order to disambiguate between the decoder tone
mapping error, and general video format support error.

Unstuck the muxer if the next timestamp in the track with the minimum
timestamp is larger than this minimum timestamp plus
MAX_TRACK_WRITE_AHEAD_US.

Before, if the upstream AssetLoader provides HDR to the VideoSamplePipeline when
HDR_MODE_EXPERIMENTAL_FORCE_INTERPRET_HDR_AS_SDR is requested, the
VideoSamplePipeline would attempt to tell the AssetLoader to output SDR, which
could be accomplished via MediaCodec tone-mapping in the AssetLoader.
However, this makes an assumption of the AssetLoader implementation, and
AssetLoaders may not all implement support for decoder tone-mapping. Remove javadoc
attempting to explain how AssetLoaders (ex. custom ones) could behave.

This method uses sampleRate, channelCount and pcmEncoding, so passing
AudioFormat is easier.
This will lead into a future change that builds the
encoderInputAudioFormat from encoder.getConfigurationFormat()

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.

Format.toString unfortunately doesn't log colorInfo, and as Format holds a very
large set of values, it's unclear that it should. ColorInfo is useful for codec
exceptions though, so log this in ExportException.createForCodec.

Otherwise, a lack of HDR decoding support will result in the tests checking output files for HDR output, like HdrEditingTest.transform_noRequestedTranscode_hdr10File_transformsOrThrows, failing.
