The method was recently introduced and only searched for matching
samples up to index==length. However, SampleQueue uses a circular
array to index its data and the search should continue until
relativeStartIndex+length, while also handling the overflow
in the circular array.
The tests for seeking didn't cover these overflow cases yet
because they always started writing data in an empty SampleQueue.
This can be fixed by prewarming the queue with placeholder data
to force using the overflow logic in the various seek methods.

When hardware buttons are used to control the volume of the remote device, the call propagates to `MediaSessionCompat.setPlaybackToRemote(volumeProviderCompat)`. However, `volumeProviderCompat` was created incorrectly when the new device volume commands were present (COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS and COMMAND_ADJUST_DEVICE_VOLUME_WITH_FLAGS), i.e. with volumeControlType = `VOLUME_CONTROL_FIXED`. This resulted in `VolumeProviderCompat` which doesn't call `onSetVolumeTo` or `onAdjustVolume` and hence doesn't propagate the calls to the `Player`. Instead, it only worked with the deprecated commands which ensured the volumeControlType was `VOLUME_CONTROL_ABSOLUTE`.
This bug was introduced in c71e4bf1ff (1.0 media 3 release) when `PlayerWrapper`'s call to `createVolumeProviderCompat` was mostly rewritten to handle the new commands, but the two if-statements were not amended.

This fixes a bug with playing very short audio files, introduced by
fe710871aa
The existing code using floor integer division results in playback never
transitioning to `STATE_ENDED` because at the end of playback for the
short sample clip provided `currentPositionUs=189937`,
`outputSampleRate=16000` and `(189937 * 16000) / 1000000 = 3038.992`,
while `writtenFrames=3039`. This is fixed by using `Util.ceilDivide`
so we return `3039`, which means
`AudioTrackPositionTracker.hasPendingData()` returns `false` (since
`writtenFrames ==
durationUsToFrames(getCurrentPositionUs(/* sourceEnded= */ false))`).

Periods that are not the last in the manifest are always ended
and non-dynamic periods are also always ended by definition.
Also, some periods may not be able to declare their final duration
accurately and we need to account for some inaccuracy. This can be
done by testing whether no further full segment within the duration
can be expected.
If stream is not considered final and `ClippingMediaSource` is read to `endUs`, then `BaseRenderer.readSource` returns `C.RESULT_NOTHING_READ`. In that case, the `lastBufferInStreamPresentationTimeUs` is not set and the last frame is not rendered.
PiperOrigin-RevId: 554418971
This workaround was added for TS streams that do not adjust their
timestamps to start from zero. Over time, the default audio sink
logic has become more robust towards unexpected timestamps and
we no longer need this workaround to jump forward in time.
The workaround also actively caused issues by adjusting the audio
timestamps backwards if the stream starts with large negative
values. See Issue: androidx/media#291. This caused playback to get stuck due
to another bug in the first-frame rendering logic in the video
renderer that is now fixed.

We currently only force the first frame if the frame timestamp is
greater than the stream *offset*.
This is wrong for two reasons:
1. The timestamp and the offset are not comparable and it should be
the stream start position.
2. The check should only be applied at stream transitions where we
need to make sure that a new first frame isn't rendered until we
passed the transition point.
We have to fix both issues together, because fixing just issue (1)
causes seeks to before the start position to no longer render the
frame (and playback will be stuck). A new test covers this case.
We also amend the stream transition test case to actually test what it
promises to test and add a test for prerolling samples at the
beginning, to ensure the first frame is still renderered.
Issue: androidx/media#291
PiperOrigin-RevId: 552858967
We currently use 3 different booleans to track the state of the first

After this change, every queued bitmap is treated as an individual input stream
(like a new MediaItems).
This change merges the FrameDropTest and FrameDropPixelTest into one (while maintaining all the test cases)
- This is accomplished by generating bitmaps with timestamps on it in FrameDropTest and compare them with goldens (one may call this a pixel test, please lmk if you want this to be renamed)
- 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

Linked to this, when silence followed an item with audio, the silence

silence queued EOS, resetting APP.isEnded back to false, so AudioGraph

This tracker aims to replicate the behavior of a specific codec to

The main demo app was still targeting API 29 to avoid scoped storage
restrictions. It is now updated to 34 (like the rest of the demo apps)
and handles scoped storage as it should handle it.
More specifically:
- We need to request READ_MEDIA_... permissions instead of
READ_EXTERNAL_STORAGE from API33.
- The legacy scoped storage opt-out can be removed
- READ_MEDIA_... permissions don't allow arbitrary file access
if the file doesn't end in a typical media file extension, so
this change adds a remark on the guide page to place samples
in the app-specific directory.
- We also don't have to request permissions for the app-specific
directories.
- Custom json files can't be placed in arbitray local locations
because they don't end in a media file extension, as there is
no way we can request a permission to load them. This means we
can remove the storage request logic in SampleChooserActivity.

This was done because it was deemed correct to only start at timestamp

This fixes two things in one go:
1. In order to indicate 'end of a cue' **without** relying on
`CuesWithTiming.durationUs`, `SubripParser` should have been emitting
an empty `List<Cue>` instead of the current behaviour of a
single-item list with `cue.text=""`.
2. There's no need for the empty cue (or cue list), we can use
`durationUs` to indicate the end of each list of cues.
There's no real need to ever have a `Cue` with `text=""`, so also
deprecate `Cue.EMPTY`.

Reading a discontinuity from a media period indicates that a position
reset is required. As part of this event, the media period may need
further loading (e.g in a MergingMediaPeriod where one stream reported
a discontinuity and the other need to reload from this position).
This currently fails if the media periods was already fully loaded and
we started loading further items in the playlist. As a result, playback
is stuck forever. We can fix this by detecting that further loading is
needed and resetting the loading period to the current one.
The existing MergingPlaylistPlaybackTest already covers this case
reliably, because it combines all the right preconditions (merging
source, clipping to get a discontinuity and a playlist).

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

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

`EGL14` was added in API 17, so move all references into the `Api17` wrapper

Remove some defensive calls to check that a context is current. Checking for GL
errors after calls should catch the case of calling GL methods without a
context (which is also only likely to come up early in development), and these
checks were not done consistently across all methods anyway. That allows
removing the API 17 requirement from `SceneRenderer` (where previously it
wasn't documented).

The streams return end-of-input if they read no samples, but know that
they are fully buffered to at least the clipped end time. This helps to
detect the end of stream even if there are no new buffers after the end
of the clip (e.g. for sparse metadata tracks).
The race condition occurs because the buffered position is evaluated
after reading the sample. So between reading "no sample" and checking
the buffered position, the source may have loaded arbitrary amounts
of data. This may lead to a situation where the source has not read
all samples, reads NOTHING_READ (because the queue is empty) and then
immediately returns end-of-stream (because the buffered position
jumped forward), causing all remaining samples in the stream to be
skipped. This can fixed by moving the buffered position check to
before reading the sample, so that it never exceeds the buffered
position at the time of reading "no sample".

When a renderer is pre-enabled (while another playback is still
ongoing), we pass mayRenderStartOfStream=false to Renderer.enable.
This ensures we don't show any first frames while the previous media
is still playing.
Currently, we never tell the renderer when we actually stop playing
the previous media so that it could render the start of the stream,
because we allow this as soon as the renderer is in STATE_STARTED and
we assume that we have to be in STATE_STARTED to make this stream
transition.
While this assumption is true, there are also cases where we can't
start the renderers because they are not ready yet and the video
renderer can't become ready because it didn't render its first frame.
This effectively blocks playback forever.
The most direct way of solving this, is to tell the renderer that
playback has transitioned and that it is now allowed to render the
start of the stream. This means it can never get blocked as described
above.

PiperOrigin-RevId: 547193927
For sync-sample-only formats, we have an optimization to drop all buffers
with less than the start time when writing them to the queue.
For the same formats, if we set a new start time (=seek), we only seek
to the buffer at or before the start time. This means the first sample
in the queue is different depending on whether we seek to a start time
or set a start time and then write samples. This is inconsistent and
effectively means the first sample depends on a race condition between
the Loader thread (writing samples) and the playback thread (attempting
an initial seek in the already loaded samples).
The effect of this inconsistency is that we have to decode one sample
we don't need (and could have skipped) and that some tests become flaky
if the test setup runs into the mentioned race condition.
The fix is to change the SampleQueue seek method to also seek to
a sample at or after the specified time, to align the behavior to the
case where we write the same samples to an empty queue.
The change also clarifies the Javadoc of
MimeTypes.allSamplesAreSyncSamples to note that this should really only
return true if the samples have no "duration" that matters. Otherwise,
we could reasonably return true for most subtitle formats although it
would break subtitle display because we'd remove samples that start
before the seek time.

We currently only log the input buffers to the codec, but the test

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.

When selecting progressive and HLS tracks, we currently check if
we can either seek in the existing samples or are starting from the
beginning of the stream. In both cases, we don't need to reload the
stream and can continue reading.
Seeking to the beginning isn't side-effect free though because it
also sets the startTimeUs to zero. Whether a seek to the beginning
is successful also depends on whether we already loaded a sample or
not. This mean that the startTimeUs value is set (or not set) based
on the speed of the Loader thread even for the same input starting
from the beginning. This race condition means the actual samples
we write to the stream may differ if the stream has initial samples
with negative timestamps.
We can avoid this race condition by checking if the queue is empty
first, so that we only call seekTo if really needed.

Robolectric writes warnings to the log output because the Surfaces

We have the optimization to skip buffers if the release time is
exactly the same as the one for the previous buffer. This makes
sense under the assumption that these buffers get released to
a visible Surface and will be ignored anyway.
However, it's also helpful to provide a customization option to not
do this for cases where the outputting MediaCodecAdapter is not
directly talking to a visible Surface or for tests where we can't
fully control the vsync timing of the Surface and want to ensure
we output all samples that are meant to be shown.

This plumbs a duration through `SampleQueue` which will make it easier
to handle transcoding muxed subtitles from e.g. SubRip to
`text/x-exoplayer-cues`.
This change is a no-op to the end-to-end behaviour of ExoPlayer because
currently we only support parsing sideloaded subtitles before
`SampleQueue`, and by adding the duration we don't affect the cues that
are ultimately output by `Player.Listener.onCues` (as shown by no change
to the golden files for `WebvttPlaybackTest` in this commit).
I considered making `CuesWithStartTimeAndDuration` implement
`Bundleable` (and deleting `CueEncoder/Decoder`) but decided against
it because we are deliberately not encoding `startTimeUs` (since that's
encoded as the sample time in `SampleQueue`). I also considered
introducing another type that only has `List<Cue>` and `durationUs`
fields, but it didn't seem necessary, since we want `startTimeUs`
everywhere else (except inside `SampleQueue`).

`MediaControllerImplBase` has 2 methods for updating listeners about `PlayerInfo` changes - `updatePlayerInfo` (for masking the state) and `onPlayerInfoChanged` (when communicating with the session). There is a set number of listener callbacks related to `PlayerInfo` updates and both methods should go through the same control flow (whether we know that masking will ignore most of them or not).
A unified method `notifyPlayerInfoListenersWithReasons` encapsulates only the shared logic of 2 methods - listeners' callbacks. This ensures that both methods call them in the same order and none are missed out.

This change uses this new method everywhere we currently `instanceof`

wrapping/delegating `Extractor` instances - because the `instanceof`

HLS is a slightly different case, because it directly re-instantiates
`Extractor` instances, which is not compatible with an arbitrary
wrapping structure. Luckily the only `Extractor` instances that HLS
re-instantiates do not support muxed subtitles, so won't be wrapped
in the first place (although future changes might use the
delegating-`Extractor` pattern for other purposes, which might affect
HLS).

When an app tried to re-prepare a live streeam with server side inserted
ad after a playback exception, the player tried to find the ad group by
its index in the ad playback state of the next timeline when creating
the first period.
If a source that supports server side ad, has removed the ad playback
state when the source has been removed, this causes a crash. For live
streams this is a reasonable thing to do given the exception could be
caused by an invalid ad playback state.
This change removes the ad metadata from the current period for live
streams and the timeline. In case the ad playback state is not reset
by the source, the first timeline refresh would ad the metadata again.
