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).

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 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.
PiperOrigin-RevId: 548705032
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.

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.
PiperOrigin-RevId: 547189941
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.

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`).

Previously `AsynchronousMediaCodecCallback.mediaCodecException` was

The result after that commit was that we would **only** suppress/ignore
the expression if a flush was currently pending, and we would throw it
both before and after the flush. This doesn't really make sense, so this
commit changes the behaviour to also throw the exception during the
flush.
This commit also corrects the assertion in
`flush_withPendingError_resetsError` and deflakes it so that it
consistently passes. The previous version of this test, although the
assertion was incorrect, would often pass because the
`dequeueInputBuffer` call would happen while the `flush` was still

When MediaCodecRenderer is given an empty sample stream, it puts

We can fix this by:

more than one change at once (this fixes the tracking for empty
sample streams that are not the first in the queue).
- Checking if none of the previous streams queued any samples in
onStreamChanged to handle this in the same way as the case
where we already output all samples (this fixes the problem when
the empty sample stream comes first in the queue).
- Also calling onProcessedStreamChange for the case above, which

- a live server side inserted postroll placeholder can be inserted to
a `AdPlaybackState` in well-defined and tested way (helper method)
- a postroll placeholder is NOT ignored when
`AdPlaybackState.getAdGroupIndexAfterPositionUs` is called (this
is required when evaluating the `nextAdGroupIndex`).
- a postroll placeholder is ignored when
`AdPlaybackState.getAdGroupIndexForPositionUs` is called (this is
required to not attempt to play the ad and is analogous to ignore the
post roll placeholder in a single period timeline).
- `MediaPeriod.getFollowingMediaPeriodInfo()` does not include a
`MediaPeriodInfo` for the placeholder postroll when building the
queue.

Playback parameter signalling can be quite complex because
(a) the renderer clock often has a delay before it realizes
that it doesn't support a previously set speed and
(b) the speed set on media clock sometimes intentionally
differs from the one surfaced to the user, e.g. during
live speed adjustment or when overriding ad playback
speed to 1.0f.
This change fixes two problems related to this signalling:
1. When resetting the media clock speed at a period transition,
we don't currently tell the renderers that this happened.
2. When a delayed speed change update from the media clock is
pending and the renderer for this media clock is disabled
before the change can be handled, the pending update becomes
stale but it still applied later and overrides any other valid
speed set in the meantime.
Both edge cases are also covered by extended or new player tests.

MediaCodecRenderer currently has two independent paths to trigger
events at stream changes:
1. Detection of the last output buffer of the old stream to trigger
onProcessedStreamChange and setting the new output stream offset.
2. Detection of the first input buffer of the new stream to trigger
onOutputFormatChanged.
Both events are identical for most media. However, there are two
problematic cases:
A. (1) happens after (2). This may happen if the declared media
duration is shorter than the actual last sample timestamp.
B. (2) is too late and there are output samples between (1) and (2).
This can happen if the new media outputs samples with a timestamp
less than the first input timestamp.
This can be made more robust by:
- Keeping a separate formatQueue for each stream to avoid case A.
- Force outputting the first format after a stream change to
avoid case B.

Robolectric allowed tests to incorrectly use the constructors on older SDK
levels (where they were non-public). This most commonly occurs for
AccessibiltyEvent and AccessibilityNodeInfo.
2) When reflection was used to instantiate classes that were instrumented by
Robolectric, all constructors were accessible.
Fix issues across Google3 Robolectric tests that were affected by this issue.
A forthcoming change will fix the instrumentation in Robolectric to prevent
this type of issue from occurring.
Tested:
TAP --sample ran all affected tests and none failed

If a renderer error happens while processing readahead data for the
next item in the playlist, we currently throw the error immediately
and only set the item id in the error details. This makes it harder
to associate the error to the right item. For example, the user
facing UI is likely not updated to show the failing item when the
error is reported.
This can be improved slighly by force setting the position to the
failing item. The playback still fails immediately, but this can't
be avoided because the renderer itself went into an error state.

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).

Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.
Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.
Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

This inconsistency was exposed by an upcoming change to deprecate
`POSITION_UNSET` in favour of `INDEX_UNSET` because position is an

Our FakeClock generally makes sure that playback tests are fully
deterministic. However, this fails if the test uses blocking waits
with clock.onThreadBlocked and where relevant Handlers are created
without using the clock.
To fix the flakiness, we can make the following adjustments:
- Use TestExoPlayerBuilder instead of legacy ExoPlayerTestRunner
to avoid onThreadBlocked calls. This also makes the tests more
readable.
- Use clock to create Handler for FakeVideoRenderer and
FakeAudioRenderer. Ideally, this should be passed through
RenderersFactory, but it's too disruptive given this is a
public API.
- Use clock for MediaSourceList and MediaPeriodQueue update
handler.

Currently, repeating the same item (via seekNext/Previous) implicitly
results in a seek to the default position of the current item, which
looks exactly the same as a direct seek. As a result, we don't send
onMediaItemTransition as we would for every other seekNext/Previous
call.
This can be fixed by explicitly marking the repeat case in the internal
BasePlayer/ExoPlayerImpl methods, so that the callback can be triggered.

We already have logic to end all session except the current one if the
current one doesn't have a MediaPeriodId yet. This is assuming that this
only happens after a seek on the app side where the player doesn't have
detailled knowledge about the MediaPeriodIds yet.
Currently this logic isn't triggered if the window we are coming from
doesn't have its MediaPeriodId either as we run into another check that
keeps sessions around until we have a valid windowSequenceNumber.
Swapping both conditions fixes this case without breaking any of the
other known transition scenarios.

If the sample type is Dolby Vision and the display does not support Dolby Vision, then the capabilities DecoderSupport flag is set to DECODER_SUPPORT_FALLBACK_MIMETYPE. This denotes that the renderer will use a decoder for a fallback mimetype if possible. This alters track selection as tracks with DecoderSupport DECODER_SUPPORT_PRIMARY are preferred.

If the back buffer is using too much memory, there is a risk
playback could get stuck because LoadControl refuses to load
further data. This eventually results in a stuck-buffering
playback error.
We can detect this case, clear the back buffer and then ask
the LoadControl again to avoid failing playback in such a case.

The stream offset is used to calculate the presentation time of
a metadata object when reading and later when playing, to calculate
the current presentation time to decide whether to send the metadata
to the output.
Accordingly, the presentation time of a pending metadata that has been
calculated with a given offset needs to be recalculated when the
stream offset changes.

considered equal, which resulted in no call to
Player.Listener.onTimelineChanged when calling
ExoPlayer.setShuffleOrder. This in turn resulted in no call to

that the new shuffle order is used when constructing the masked

1. The offloadSchedulingEnabled value doesn't need to be in
PlaybackInfo because it's never updated in EPII.
2. The sleepingForOffload value in EPII wasn't updated explicitly
(just via the return value of a method). It was also only
meant to be enabled while the player is actively playing, but
confusingly triggered from a path where the player may
theoretically be buffering as well.
3. The offload sleeping (=not scheduling doSomeWork) was interwoven
into the actual scheduling code making it slightly hard to follow.
This can be improved slightly by keeping the offload sleeping
decision and the scheduling separate.

Some Player implementations have no playlist capability but can still
set a MediaItem for playback. Examples are a MediaController connected

that replaces everything that is currently played.

We generally nest the `Builder` for `Foo` inside `Foo`. In this case,
there's already a `DefaultTrackSelector.Parameters.Builder` type visible
to a developer, it just happens to be the 'common'
`TrackSelectorParameters.Builder`, so using it is a bit weird. For
example this code snippet doesn't compile because
`DefaultTrackSelector.Parameters.Builder#build()` returns
`TrackSelectionParameters`. This CL fixes that problem and the code
snippet now compiles.

DefaultTrackSelector.Parameters params =
new DefaultTrackSelector.Parameters.Builder(context).build()

Unconditionally sleep for offload, if the audio buffer is full.
Previously ExoPlayer would not sleep if the expected wake-up was
in 2s. This was to prevent underrun if the wake-up was delayed.
Experiments have shown that the wakup audio buffer is far more
than 2s (around 1min). Additionally,
the metric was incorrect because it measured both,
AudioTrack + DSP.
Finally, this metric was erroneous after a gapless transition,
when the head position would reset to 0 and thus the computed
delay until next wakeup was too large.
