An audio file can only play sound between two PCM samples (the 'start'
and 'end' of section of a wave form). Therefore when calculating
duration from a count of PCM samples we need to subtract one first (the
'end' sample which has no duration of its own).
This only changes durations by one PCM sample (21us - 22us for 44.1kHz sample
rate).

The extractor knows the PCM encoding of the losslessly
encoded data in the samples and should set it in the
Format to allow downstream components to use this information.

We introduce SubtitleParser.Factory that supports no formats to be used FragmentedMp4Extractors that will not do any subtitle parsing on the extraction side. We also slowly move away from using SubtitleTranscodingExtractor to SubtitleTranscodingExtractorOutput (hence making it public).
This is required by individual Extractor impls so that they can start using SubtitleTranscodingExtractorOutput rather than be wrapped by SubtitleTranscodingExtractor. The latter is to be deprecated after all the subtitle related Extractors have achieved this migration.

Whenever the inputColorInfo updates, update the samplingGlShaderProgram.
Also, allow either SDR or gamma2.2 to be used for HDR->SDR tone-mapping
`outputColorInfo` request. This is required because we can't update the
`outputColorInfo`, but plan to always use gamma2.2 for `outputColorInfo` in the
future.
This allows VideoFrameProcessor to work as is for exoplayer previewing, but
only when not seeking. As we haven't plumbed the per-stream inputColorInfo from
ExoPlayer down to VFP.registerInputStream, follow-up CLs will be needed to
properly support previewing with changing inputColorInfo.

This behavior was previously available as opt-in via
`MediaItem.DrmConfiguration.Builder.setPlayClearContentWithoutKey` and
`DefaultDrmSessionManager.Builder.setPlayClearSamplesWithoutKeys`. This
change flips the default of both these properties to true.
This should speed up the time for playback to start when playing DRM
content with a 'clear lead' of unencrypted samples at the start.
Previously playback would wait until the keys for the later encrypted
samples were ready. The new behaviour could result in mid-playback
stalls/rebuffers if the keys are not ready yet by the transition from
clear to encrypted samples, but this is not really a regression since
previously playback wouldn't have started at all at this point.

PiperOrigin-RevId: 595701540
When the media notification controller is requested for a session
with `getConnectedControllerForSession` and the `Future` is not null
but not yet completed, the `Future` was returned either way. This was
reported as creating a race condition between the notification
being requested for update the very first time, and the media
notification controller having completed connecting to the session.
Returning null from `getConnectedControllerForSession` when the
`Future` is available but not yet done fixes the problem. This is
safe because for the case when a notification update is dropped,
the media notification controller will trigger the update as soon
as the connection completes.

`Cea608Parser` and `Cea708Parser` don't currently work correctly on
their own without the re-ordering of input buffers implemented in
`CeaDecoder`, and it's not clear how we can properly do this re-ordering
during extraction. This change ensures that if 'parse subtitles
during extraction' is enabled, CEA-6/708 subs will be passed through
without transcoding and can then be decoded during rendering by
`Cea6/708Decoder`.
PiperOrigin-RevId: 595658628
Invalid frames have no impact on ExoPlayer ability to play the media and should not fail on errors.
Some tools can add 100Mb images in the tags that will trigger recoverable OOM with this fix.
The `Cea608DecoderTest` added here fails if re-ordering is removed from
`CeaDecoder`.
The `Cea608ParserTest` is added with `@Ignore` because there's currently
no re-ordering support in this part of the subtitle handling pipeline
(partly because there's no concept of 'current playback time', meaning
it's hard to know **when** to re-order).

When the 'when' timer of the notification is disabled
`DefaultMediaNotificationProvider` may set `C.TIME_UNSET`

This change sets `0L` instead of `C.TIME_UNSET` when the

Mp4Muxer does not support out of order B-frames. Currently it
silently writes out of order B-frames, producing an invalid file (with
negative sample durations).
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
running `sample.mp4` via `Transformer` after applying some effects.
PiperOrigin-RevId: 594016144
This more closely matches the intended, documented behaviour of this
method. The previous implementation was incorrectly checking
`sampleDataEnd + newSampleSize`, but it's more correct to compare
`existingSampleDataLength + newSampleSize`, in order to handle the
case of non-zero `sampleDataStart`. We've already checked above whether
`newSampleSize` fits after `sampleDataEnd` without growing or
reshuffling the array, so no need to basically repeat that check.
In the case of handling one sample at a time, the previous
implementation resulted in `sampleData` growing by `sampleSize`
**every time** the pointers reached the end. With the new check for
`sampleDataStart == sampleDataEnd`, this is avoided by always writing
each new sample at the start of the array (because the previous sample
has already been consumed), meaning `sampleData` remains equal to
`sampleSize` without growing.

These were missing in 5211ff0dc1
Without these, the `": null"` is still logged (but the `"Unexpected

concatenation is compared to null as the boolean condition of the

concatentation is never `null`) i.e. (with excess parentheses for
clarity):
```
(("Unexpected " + cause.getClass().getSimpleName() + cause.getMessage()) != null)

Also add a test because obviously this isn't as simple as I'd thought.

This is similar to the HLS fix in 770ca66fbc
Similar to HLS, the original problem here was **not** modifying the
`Format` for caption tracks
embedded into the video stream. I tried just updating the format in
both places, but that caused new failures because the new
('transcoded') format was then fed into `FragmentedMp4Extractor` as
part of `closedCaptionFormats`, which resulted in the CEA-608 data
being emitted from `FragmentedMp4Extractor` with the incorrect
`application/x-media3-cues` MIME type (but the bytes were actually
CEA-608), meaning the transcoding wrapper passed it through without
transcoding and decoding failed (because obviously CEA-608 bytes can't
be decoded by `CueDecoder` which is expecting a `Bundle` from
`CuesWithTiming.toBundle`.
To resolve this we keep track of the 'original' caption formats inside
`TrackGroupInfo`, so we can feed them into `FragmentedMp4Extractor`.
For all other usages in `DashMediaPeriod` we use the 'transcoded'
caption formats.
PiperOrigin-RevId: 592866262
With fMP4 implementation there will be two writers `DefaultMp4Writer`

Changes includes:
1. Make Mp4Writer as an abstract class and keep only common functionality

2. Create a DefaultMp4Writer which contains existing logic to write MP4.
3. The fMP4 logic needs to access `pending sample buffer info` at various
places, so did refactoring to split List<Pair<BufferInfo, ByteBuffer>>
into two separate lists.

Issues with the current implementation
1. The implementation is unnecessarily complicated and can be
easily simplified.To make all the tracks start from the same time,
its only the first sample that require some timestamp adjustments
but the current implementation shifts all the timestamps. Since method
calculates the `sample duration`, shifting all the timestamps has no effect
as such.
2. The implementation always forced first sample to start at 0. But when we
want to use same method for `Fragmented MP4` then it will look inaccurate
as we will call this method for different `fragments` and each `fragment`
will not start from 0 presentation time. Although the output will be same
since this method returns `duration` and not the `timestamps`.
3. As per previous implementation if there is just one sample then
its duration is made equals to its presentation time, which looks incorrect.
With new changes, if a single sample is passed then its duration will always
be 0 irrespective of specified last sample duration behaviour.

getAudioCapabilities currently creates the receiver and returns
the current capabilities. This is error-prone because the

HLS distinguishes between 'subtitles' (WebVTT or TTML distributed in
separate files with their own playlist) and 'captions' (CEA-608 or 708,
distributed muxed into the video file).
The format transformation added in 7b762642db
only applies to subtitles and not captions. This change makes the same
transformation for caption formats.
This resolves an error like:
```
SampleQueueMappingException: Unable to bind a sample queue to TrackGroup with MIME type application/cea-608.
```
Also add two playback tests for HLS CEA-608, one that parses during
decoding (old way) and one during extraction (new way). Adding these
tests is what alerted me to this issue.

This was generated by combining the existing `ts/bbb_2500ms.ts` test
asset and a temporary `.srt` file using

This doesn't directly reproduce the problem fixed by
7ca26f898d,
because the CEA-608 subs are structured differently to the stream I
discovered the problem with (from Issue: androidx/media#887). However this test
does fail if that fix is reverted after

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

This stream does provide some regression protection, because it
currently fails with 'new' subtitle parsing
(`DashMediaSource.Factory.experimentalParseSubtitlesDuringExtraction(true)`),
though I'm not sure on the exact reason for that yet.

We deliberately left `Cea608Decoder` and `Cea708Decoder` intact when
creating the respective `SubtitleParser` implementations (in
27caeb8038
and
94e45eb4ad
respectively).
However we didn't correctly change the behaviour of
`SubtitleDecoderFactory.DEFAULT` in order to use these 'legacy'
implementations. We firstly left the `Cea608Decoder` instantiation
**after** the `DefaultSubtitleParserFactory.supportsFormat()` check,
meaning that code would never be reached (since `supportsFormat` now
returns true for CEA-608). Then in the second change (which was supposed
to only be about CEA-708) we removed all instantiations of **both**
`Cea608Decoder` and `Cea708Decoder`. This change puts the decoder
instantiations back and moves them above the
`DefaultSubtitleParserFactory.supportsFormat` check, meaning they will
be used in preference to `DelegatingSubtitleDecoder`.
This resolves the immediately-disappearing subtitles tracked by

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.

When track is changed during playback, `playbackPositionUs` may be in middle of a chunk and `loadPositionUs` should be the start of that chunk. In this situation `loadPositionUs` can be less than the current `playbackPositionUs`, resulting into negative `bufferedDurationUs`.

The timestamp adjuster also estimates the number of wraparounds
of the 90Khz TS timestamp. It does that by assuming that a new
timestamp is always close to the previous one (in either direction).
This logic doesn't always work for duration estimates because the
timestamp at the end of the media is not close to the one at the
beginning and it may also never be less than the one at the beginning.
This can be fixed by introducing a new estimation model that assumes
the new timestamp is strictly greater than the previous one without
making the assumption that it has to be close to it.

Despite GL 3.0 not being required on API 29+, it is experimentally

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

We currently pause playback to prevent further progress while the
app thread runs assertion and triggers additional actions. This is
not ideal because we do not actually want to pause playback in

This can be improved by keeping the playback thread blocked and only
unblock it the next time the app thread waits for the player (either
via RobolectricUtil methods or by blocking the thread itself). To
add this automatic handling, this change introduces a new util class

This change moves the instantiation of the CompositingVideoSinkProvider
out of MediaCodecVideoRenderer so that the composition preview player can
re-use the CompositingVideoSinkProvider instance for driving the rendering of

The main point of the change is the ownership of the
VideoFrameReleaseControl, which decides when a frame should be rendered
and so far was owned by the MediaCodecVideoRenderer. With this change,
in the context of composition preview, the VideoFrameReleaseControl
is no longer owned by MediaCodecVideoRenderer, but provided to it.
This way, the CompositingVideoSinkProvider instance, hence the
VideoFrameReleaseControl can be re-used to funnel images into the

`mediaCrypto` is initialized before `codec` in
`maybeInitCodecOrBypass`. Before this change, it was possible for
`maybeInitCodecOrBypass` to complete with `mediaCrypto != null` and
`codec == null`, in particular if it was run as part of clearing the
player surface (since in that case, no video codec is initialized).
This inconsistent state then causes issues during a later invocation of
`maybeInitCodecOrBypass`, when `mediaCrypto` is still non-null, and
`mediaCryptoRequiresSecureDecoder = true`, but the
content has been changed to unencrypted with no associated DRM session.
This results in a playback error, because a secure decoder is
initialized but there's no DRM session available to work with it.
This change ensures that when `maybeInitCodecOrBypass` completes,
either both `mediaCrypto != null` and `codec != null` (i.e. codec
initialization was completed) or `mediaCrypto == null` and
`codec == null` (i.e. codec initialization was not completed). We also
ensure that when nulling out `mediaCrypto` we also set
`maybeInitCodecOrBypass = false`. A later change should be able to
demote `maybeInitCodecOrBypass` from a field to a local in order to
remove any risk of that part of state becoming out of sync. This
resolves the issue, because during the second invocation of
`maybeInitCodecOrBypass` an insecure decoder is now (correctly)
initialized and the unencrypted content is successfully played.

Statically importing values and using them directly is preferable to

`fromBundle` doesn't distinguish between `FIELD_BITMAP` and `FIELD_TEXT`
being present with a null value, or being absent, so we might as well
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.

Add an check when loading progressive media in case the load
is canceled. If the player is released very early, the progressive
media period may carry on with the initial loading unnecessarily.

In `TextOverlay` and `DrawableOverlay`, treat `Bitmap` as a buffer, where we
allocate it rarely and reuse it as long as possible before making a new one.
In `BitmapOverlay`, avoid allocating GL textures too often as well.
Strongly reduces allocations and memory usage growth (saving ~100-150 MB on 4k60fps
at high end), at the cost of more code complexity and low-end using 70MB more, on
1/1 comparisons.

In `ExternalTextureManager` fields are accessed from the GL thread and the class needs to be constructed on the GL thread.
Also visibly document threading requirement in the parent class.

The issue that motivated adding this (frames unexpectedly being dropped by the
decoder) has been addressed, so we can turn off the logging to reduce
unnecessary allocations during transformation. We can easily turn on debug
logging in future as needed by setting `DebugTraceUtil.DEBUG = true`.
Also avoid allocations for string building at logging call sites by passing a
format string for extra info. Formatting the string now only happens when
debugging is turned on.
Tested manually by running transformations in the new state (DEBUG = false) and
with debugging turned on.

Serializing bitmap cues is currently broken, but this test is
incorrectly passing. This change makes two changes to introduce the same
failure (both changes are necessary, each one alone still passes):
1. Move from Robolectric to an instrumentation test.
2. Trigger the `Bitmap` to be serialized using a file descriptor, either
by calling `Bitmap.asShared` in the test when constructing the `Cue`,
or constructing the `Bitmap` from a 'real' image byte array instead a
1x1 token image.

The decoder and encoder won't accept high values for frame rate, so avoid
setting the key when configuring the decoder, and set a default value for the
encoder (where the key is required).
Also skip SSIM calculation for 4k, where the device lacks concurrent decoding
support.

At least some Android 14 devices still have the same invalid URL issue
when using ClearKey DRM, so might as well apply the check to newer
versions of Android as well.
Using `Integer.MAX_VALUE` risks causing arithmetic overflow in the codec
implementation.

We don't get the buffer back after decoding to make a proper decision
about whether dropping the buffer is needed, so we do the next best
thing and tell the codec to drop the buffer if its input timestamp is
less than the intended start time.

Move the reflective loading of VideoFrameProcessor from
MediaCodecVideoRenderer to the CompositingVideoSinkProvider. This is so
that all reflective code lives in one place. The
CompositingVideoSinkProvider already has reflective code to load the
default PreviewingVideoGraph.Factory.

In OverlayShaderProgram, this method is used quite a lot, and is the only method from Util.java in this file. Marginally reduce complexity by using a static import instead.

Reduce short-lived allocations of potentially large objects, like Bitmap.
Unfortunately, this does make the TextureOverlay interface more messy though, requiring a way to signal whether the texture should be flipped vertically.

These changes are also compatible with FFmpeg 5.1, which is now minimum supported version.
Also set -Wl,-Bsymbolic flag via target_link_options command which is more correct.
Split CompositingVideoSinkProvider.VideoSinkImpl in two classes:
- VideoSinkImpl now only receives input from MediaCodecVideoRenderer and
forwards frames to its connected VideoFrameProcessor
- VideoFrameRenderControl takes composited frames out of the VideoGraph
and schedules the rendering of those.
- CompositingVideoSinkProvider connects VideoSinkImpl with
VideoFramesRenderer.

This change adds `MediaController.getSessionExtras()` through
which a controller can access the session extras.
The session extras can be set for the entire session when
building the session. This can be overridden for specific
controllers in `MediaSession.Callback.onConnect`.

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.

The live offset override is used to replace the media-defined
live offset after user seeks to ensure the live adjustment adjusts
to the new user-provided live offset and doesn't go back to the
original one.
However, the code currently clips the override to the min/max
live offsets defined in LiveConfiguration. This is useful to
clip the default value (in case of inconsistent values in the media),
but the clipping shouldn't be applied to user overrides as
the player will then adjust the position back to the min/max
and doesn't stay at the desired user position.

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).
