When generating silence for AudioProcessingPipeline, audio never
queued EOS downstream.
Linked to this, when silence followed an item with audio, the silence
was added to SilentAudioGenerator before the mediaItem reconfiguration
occurred. If the silence had effects, the APP would be flushed after
silence queued EOS, resetting APP.isEnded back to false, so AudioGraph
never ended.
Regression tests reproduce failure without fix, but pass with it.

For each event, the timestamp and presentation time is logged. The trace can
then be dumped to a tsv file and easily imported in a spreadsheet.

signalEndOfInputStream is needed for when streams have different amounts of
frames, so that if the primary stream finishes after a secondary stream, it
can end without waiting indefinitely for the secondary stream's matching
timestamps.
onEnded mirrors this API on the output side, which will be necessary to
know when to call signalEndOfInput on downstream components (ex. on downstream)

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

SingleInputVideoGraph implements GraphInput now, so the asset loaders would
interface directly with SIVG, rather than VideoSampleExporter. This is to pave
way for multi-asset video processing.

* Allow more than one input bitmap at a time.
* Allow Compositor to take in and set up an Executor. Otherwise,
Compositor resources may be created on one thread and accessed on another.
* Add a Compositor TestRunner to reuse test code more.
* Update VideoFrameProcessingTaskExecutor to use a new onError listener, so
that it's more reusable in non-DVFP contexts, like for Compositor.

durationUs is almost always going to be a larger number than the sample

TransformerAndroidTestRunner#run will throw any exception that occurs,

Frame buffers are focused, not current. EGL Contexts may be current but this
is a prerequisite for focusing a framebuffer, and this alone isn't
sufficient to make a bitmap.
Clear this up as it can make some complex tests harder to understand, if the
methods needed don't match up in naming.

Add documentation for threading requirements at the class level (in
addition to existing documentation on the methods) to improve
discoverablility. Also fix a couple of nits in the javadoc (US English
spelling, avoid passive voice) and in `OnInputFrameProcessedListener`.

This allows us to simplify and reduce thread initialization, hops and the
synchronization cost associated with them, especially when more and more VFPs

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
data output is. In the event that it is different, additional
AudioProcessor instances must be used to ensure the encoder will still
be able to accept the audio buffers.

Providing the sync token in the api allows the client to decide which waiting method they would like to use depending on the use case, allowing them to optimise if possible.

This fixes a broken javadoc link and makes it possible to customize media
source creation via the asset loader factory without also having to

Goal of tests (SequenceExportTest) that use this media is for the
silence and the media to match exactly with audio format, however
`sample_with_increasing_timestamps.mp4` had a different sample rate.

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.

With the upcoming "handle format changes" CL, stereo -> mono audio
would add an AudioProcessor. Robolectric decodes output encoded data,
which crashes some AudioProcessors because the number of frames may not
be an integer.

The effects pipeline must receive images in the sRGB colorspace due to the color transfers applied in the shaders. Currently the burden to making sure images are in the right colorspaces falls onto apps. This CL ensures that this is not the case anymore.

Audio only tests are now using RAW audio where possible, which is
passed through the Robolectric decoders/encoders, and can be handled by
the AudioProcessor instances accurately.

To more accurately describe what they do, especially as Compositor will
starts to use more contexts or threads, and it's important to know what

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.

The existing NullableType has been deprecated 5 years ago and causes
crashes in Kotlin apps because Kotlin doesn't recognize this annotation
as a nullable type annotation.
While we can't align on a single @Nullable annotation yet, we can at
least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all
requirements, including full Kotlin compatiblity. To avoid the
cumbersome name, we can redefine it as our own @NullableType
annotation. (We can't use @Nullable to avoid name clashes with the main
@Nullable annotation from AndroidX)

208eefc0fd introduced using `DefaultDecoderFactory.getDecoderInfo(format) != null` caused certain tests not to be skipped when they were expected to be, creating more mh failures.
PiperOrigin-RevId: 537820370
ExoPlayer extractors (backing `MetadataRetriever`) now parse the color format
from the bitstream so using `MetadataRetriever` should be an equivalent but
more lightweight way to verify the color info.
Also remove try/catch blocks in test code calling into these methods, and add
skipping based on decoder capabilities in the cases where it was missing.

In some cases the codec selected for decoding has a different MIME type than
the media. In thoses cases Transformer continued to use the media's MIME type
and that caused codec configuration failures.
Removed `EncoderUtil.findCodecForFormat()` as we stopped using the method it
uses for finding a codec. Plus, the method is only used in the test.
See also `MediaCodecUtil.getALternativeCodecMimeType()`.
