The current implementation of `JpegMotionPhotoExtractor.sniff` returns
`true` for any image with Exif data (not just motion photos). Improving
this is tracked by b/324033919. In the meantime, when we 'extract' a
non-motion photo with `JpegMotionPhotoExtractor`, the result is
currently a single empty image track and no video track (since there's
no video, since this isn't a motion photo). This 'empty' image track
is usually used to transmit metadata about the video parts of the
image file (in the form of `MotionPhotoMetadata`), but this metadata is
also (understandably) absent for non-motion photos. Therefore there's
no need to emit this image track at all, and it's clearer to emit no
tracks at all when extracting a non-motion photo using
`JpegMotionPhotoExtractor`.
This change also removes a `TODO` that is misplaced, since there's no
image bytes being emitted here (and never was).
PiperOrigin-RevId: 604688053
These are often the same for image tracks, since we usually drop the
whole image file (both the container and actual encoded image bytes)
into a single sample, but there are cases where we emit a track with
`containerMimeType=image/jpeg` but **no** samples (from
`JpegMotionPhotoExtractor`, to carry some metadata about the image +
video byte offsets).
It's therefore more correct to implement the `supportsFormat` check
based on `sampleMimeType`, so that these 'empty' image tracks are not
considered 'supported' by `ImageRenderer`.

Before supporting transmuxing when both no op effects and regular rotations are set, move setting the muxerWrapper rotation out of shouldTranscodeVideo() to ensure the muxerWrapper rotation is only set at the appropriate times.
This cl also ensures the state between the muxerWrapper and the list of video effects is consistent by clearing the list of videoEffects in trim optimization. If trim optimisation is being applied, then EditedMediItem.effects.videoEffects only contains no-op effects or regular rotations that get be applied in the muxer wrapper. Therefore, we should clear the list of video effects to ensure that no effect gets applied twice.

The new test introduced in 45bd5c6f0a is flaky because we only

interactions) are flaky.
This can be fixed by fully playing the media once and then seeking

Previously, input assets had to be all SDR or all HDR.
After this CL, if tone-mapping is requested, HDR and SDR may mix in any order. If tone-mapping is not requested, SDR may precede HDR, but not vice versa, until SDR to HDR tone-mapping is implemented

1. Inputting the decoded format's color to VideoFrameProcessor.registerInputStream
for each stream.
2. Calculating the estimated decoded format's color for each stream, by estimating
it based on MediaCodec tone-mapping.

As per MP4 spec ISO 14496-12: 8.7.5 Chunk Offset Box, Both "stco" and
"co64" can be used to store chunk offsets. While "stco" supports 32-bit
offsets, "co64" supports 64-bit offsets.
In non fragmented MP4, the mdat box can be extremely large, hence muxer
uses "co64" box.
But for fragmented MP4, muxer does not write any data in this chunk offset
box (present in "moov" box) because all sample related info is present in
"moof" box.
Technically, "co64" box should also work in fragmented MP4because
its empty only but QuickTime player fails to play video if "co64"
box is present in fragmented MP4 output file.

The seek table in a Xing/Info header is very imprecise (max resolution
of 255 to describe each of 100 byte positions in the file). Seeking

An audio file can only play sound between two PCM samples (the 'start'

duration from a count of PCM samples we need to subtract one first (the

This only changes durations by one PCM sample (21us - 22us for 44.1kHz sample
rate).

Mp4Muxer does not support out of order B-frames. Currently it
silently writes out of order B-frames, producing an invalid file (with

Although `Mp4Extractor` is somehow able to process this invalid file and
`Exoplayer` is able to play it but that is unexpected.
The `sample.mp4` test file contains B frames. Other test files does not
contain `H264 video + AAC audio` format hence created a new test file by

HLS distinguishes between 'subtitles' (WebVTT or TTML distributed in
separate files with their own playlist) and 'captions' (CEA-608 or 708,

only applies to subtitles and not captions. This change makes the same
transformation for caption formats.
This resolves an error like:
```

I'm also not able to repro the character duplication reported in
Issue: androidx/media#887 by just changing the manifest in this CL. I'm not yet
sure on the exact differences between the stream provided on GitHub

(`DashMediaSource.Factory.experimentalParseSubtitlesDuringExtraction(true)`),
though I'm not sure on the exact reason for that yet.

This is because currently
1. Player sets a surfaceView to render to
2. Player intializes the renderer
3. MCVR initializes the VideoSinkProvider, by extension VideoGraph
But when 1 happens, MCVR doesn't set the surfaceView on the VideoGraph because
it's not initialized. Consequently after VideoGraph is initialized, it doesn't
have a surface to render to, and thus dropping the first a few frames.

The MP4 data in JPEG motion photos can contain multiple `video/hevc` tracks, but only the first is at a playable frame rate while the others are low-fps, high-res tracks designed for specific use-cases (not direct video playback).
ExoPlayer currently selects the unplayable track by default, because it
has a higher resolution. This change introduces a flag to
`Mp4Extractor` that results in the first video track being marked as
`ROLE_FLAG_MAIN`, and all subsequent video tracks `ROLE_FLAG_ALTERNATE`
- this then results in the playable lower-res track being selected by
default.

This test demonstrates ExoPlayer's current behaviour default extraction

`fromBundle` doesn't distinguish between `FIELD_BITMAP` and `FIELD_TEXT`

avoid including them when the value is null.
I've separated this from a later change to add
`Cue.toSerializableBundle` which will also skip setting a bitmap value
into the `Bundle` if `this.bitmap == null`. This is partly because it
results in changes to a lot of extractor test dump files, and it's
easier to review that as a separate change.

This change fixes a bug with seeking forward in MIDI. When seeking forward,
the progressive media period attempts to seek within the sample queue, if a
key-frame exists before the seeking position. With MIDI, however, we can
only skip Note-On and Note-Off samples and all other samples must be sent
to the MIDI decoder.
When seeking outside the sample queue, the MidiExtractor already
instructs the player to start from the beginning of the MIDI input. With
this change, only the first output sample is a key-frame, thus the
progressive media period can no longer seek within the sample queue and
is forced to seek from the MIDI input start always.

When transmuxing, the `EncodedSampleExporter` maintains a queue of input
buffers that get filled with encoded data by the asset loader. The number of
buffers was limited to avoid using more and more memory if producer (asset
loader) gets far ahead of the consumer (exporter).
Previously this limit was fixed at 10 buffers, but increasing the number of
buffers can make some transmux operations much faster. Allow allocating between
a min and max number of buffers, and also set a target allocation size beyond
which new buffers can't be allocated. This allows audio formats which require
many small buffers to be processed more quickly, while preventing allocating
too much memory for hypothetical very high bitrate formats.
'Remove video' edits on local videos in particular get much faster, because
audio buffers are very short and there are lots of them. With a sample 10
minute video, a 'remove video' edit took 2 seconds (36 seconds before this
change). With a sample 1 minute removing video took 0.25 seconds after this
change (2.5 seconds before).
The speed improvement is smaller for other types of edits that retain the video
track. Transmuxing a 10 minute video retaining the video track took 26 seconds
(40 seconds before).

The dump file diff as part of this change is because using AudioGraph

This is equivalent to the existing `scaleLargeTimestamp` method with the
following changes/improvements:
* No longer specific to timestamps (there was nothing inherently

and docs suggested it shouldn't be used for non-timestamp use-cases).
* Additional 'perfect division' checks between `value` and `divisor`.
* The caller can now provide a `RoundingMode`.
* Robust against `multiplier == 0`.
* Some extra branches before falling through to (potentially lossy)
floating-point math, including trying to simplify the fraction with
greatest common divisor to reduce the chance of overflowing `long`.
This was discussed during review of 6e91f0d4c5

Periods that are not the last in the manifest are always ended

After this change, every queued bitmap is treated as an individual input stream

- The most part of the change comes from DefaultVideoFrameProcessorVideoFrameRenderingTest. The overall working is
- We bypass the input manager
- The TestFrameGenerator generates frames based on timestamps. In this case, we generate frames with timestamps on it
- The generated frame is sent to texture output and in turn saved to bitmaps
- We then compare the generated bitmap with the goldens

When generating silence for AudioProcessingPipeline, audio never
queued EOS downstream.
Linked to this, when silence followed an item with audio, the silence

silence queued EOS, resetting APP.isEnded back to false, so AudioGraph
never ended.

The end-to-end test output for the overlapping SRT and SSA subtitles
is currently incorrect. They will be fixed in a future change that
updates `TextRenderer` to support this overlap.
The 'extra' samples visible in the extractor test output files are
'empty cue list' samples produced by `SsaParser`. They will go away
when this implementation is updated to remove this behaviour and rely
on `CuesWithTiming.durationUs` instead (the 'empty list' behaviour is
not required by the `SubtitleParser` interface).

Mark output sample as decode-only based on start time
We currently do the same check on the input timestamps and
expect the output timestamps to match. Some codecs produce
samples with modified timestamps and the logic is a lot safer
when the comparison with the start time is done on the output
side of the codec.
Issue: google/ExoPlayer#11000

This was done because it was deemed correct to only start at timestamp
zero when the code was originally written. However, in case of
prerolling from a keyframe, many samples will get the same timestamp,
which is not correct and interferes with downstream logic
that deals with timestamps.

This is a step towards adding general support for overlapping
subtitles in these formats (and others), both muxed and sideloaded:
* Issue: google/ExoPlayer#10295
* Issue: google/ExoPlayer#4794
This change adds these files to the end-to-end playback tests too, but
the subtitle track is currently disabled because renderer-side subtitle
parsing causes flaky tests (due to an uncontrolled thread in
`SimpleSubtitleDecoder`). The subtitle track will be re-enabled in
a follow-up change when loading-side subtitle parsing is added (so the
tests will no longer be flaky). At this point the overlapping subtitles
**still** won't be supported end-to-end, but a second change will
resolve this will changes in `TextRenderer` - which will change the
end-to-end playback dumps to reflect the overlapping subtitles.

Add Ogg ID Header and Comment Header Pages to the Ogg encapsulated Opus for offload playback. This further matches the RFC 7845 spec and provides initialization data to decoders.
PiperOrigin-RevId: 548080222
These tests allow to verify the samples sent for decoding,
when decoders are reset, which samples are dropped as decode-only
for video and which samples are sent to the AudioTrack for playback.
The test exercises all combinations of merges where audio or video
is the primary track and where audio, video or both are clipped.

We currently only log the input buffers to the codec, but the test
will be more complete and provide more insights into the playback
behavior if we also dump more information about these input buffers
(timestamps and flags) and also all output buffers with their
timestamps and whether they are rendererd (only relevant for video).
And also use the CapturingAudioSink to output the audio data we produce.
PiperOrigin-RevId: 546898937
Some adjustments to the test to make it more correct and prevent it
from becoming flaky:
- Use separate output dump files per test setup. Once we add more data
to these files, they are not guaranteed to be the same anymore.
- Use a seek position that is actually behind the midroll as described
in the test setup.
- Change ad insertion position to ensure the ad group duration doesn't
exceed the underlying media duration.
- Add a wait for isLoading to ensure the late insertion of an ad group
happens consistently at the same processing stage.
PiperOrigin-RevId: 546825183
This avoids issues with potential number clashes with ID_UNSET.
Also fixes some further parsing where adaptation set ids are referenced
from manifest properties.
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.
PiperOrigin-RevId: 544338451
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.
testvid_1022ms.mp4: channel count = 2, sample rate = 44100.
PiperOrigin-RevId: 543458948
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.
PiperOrigin-RevId: 542568875
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.
PiperOrigin-RevId: 541648853
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.

Previously, I assumed that SDR contents must be BT709, and HDR contents must be
BT2020. Turns out BT2020 is just wide-gamut, and SDR contents / transfers may be
represented in BT2020 color spaces.
Relax the check, so that we don't throw when valid BT2020 SMPTE 170M contents
are input into effects.

The actual csd data contains NAL units so it should always start with
a NAL unit start code (00 00 00 01).
This issue was not caught before because in the code there was no
validation to check whether its a valid NAL unit.

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.

Otherwise, this test file will be quite large, and folks who clone the repo will

- This is to make sure we know about all the tracks before initializing
the SamplePipelines. This allows to set the muxer and the fallback
listener track count before the SamplePipelines are built.
- As a result, the test files had to be updated because the order in
which the tracks are written has changed.
- The ImageAssetLoader also had to be updated to call onOutputFormat
repeatedly until it returns a non-null SampleConsumer.
- Also fix the trackCount sent to the muxer and fallback listener. The
correct track count can be computed now that we know about all the
tracks before building the SamplePipelines.

2. Feed those samples into Mp4 muxer.
3. Use extractor to extract the samples from muxed file and create dump file.

Add format codec info, which can make test skipping checks more similar to the
actual Transformer decoder checks.
Also for the test file, the actual format was 720p, but somehow the file name and
media metadata indicated 1080p. This format mismatch led to some decoding errors,
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.
