This method should be assumed to clear the data of the underlying array
(it will do this if the new limit > data.length).
This means it should only be called (directly) before writing into the
backing array.
It shouldn't be used as a shorthand for position=0, limit=x - those
should be two explicit method calls.
Most of these changes are no-ops, but they make the code more correct.
The TS SectionReader can't be easily changed to be 'safe', because it
relies on sectionData maintaining state between iterations of the while
loop. Instead I've added comments justifying the existing code.

This ensures we have full test coverage for proguard configs now.
The only configs not covered by tests are:
- IMA and OkHttp which copy recommended configs from the respective
library. I couldn't reproduce failures by removing them (and thus
couldn't write a test that ensures they are correct).
- Some dontwarn lines that just suppress warnings.
In addition, this change fixes a couple of related issues:
- Moved AV1 proguard config to correct module.
- Removed mentioning of deprecated ExtractorMediaSource from README
- Suppressed warning from IMA code that prevent proguarding under
strict rules
- Fixed wrong proguard exclusion in VP9 module.
- Moved FLAC exclusion (DefaultExtractorsFactory) to correct module.
- Added AlertDialog suppression for de-jetified code.
- Removed unusued dependency from UI module that causes large APK
size increase.

Previously the PlaybackStatsListener needed to handle all events
individually, which required to keep some state of the player and
to resolve potentially transient state changes.
Using onEvents allows to channel all simultanous updates through
one method so that no transient player state and other
inconsistencies need to be handled. This makes the logic easier
to read.
In addition it also allows to resolve all simultaneous events to
use one EventTime (with one timestamp).

In many cases it doesn't matter for the test itself how many windows
a timeline has, or even how the timeline of a MediaSource looks like.
And since we introduced the MediaItem-based APIs, single-window
Timelines are the only fully supported Timelines. Thus there is no
point in specifiying this explicitly.
Using these assumptions, we can remove some boilerplate when setting
up standard FakeTimelines or FakeMediaSources with a standard
FakeTimeline.

The current code creates placeholder metadata elements if there is no

The EventTime wasn't part of the onEvents callbacks so far because the

different media periods). By adding a query method to obtain the

Previously, VideoFrameReleaseTimeHelper didn't receive PTS values for
frames that were skipped. This would lead to unnecessary sync loss when
encountering such buffers, because the helper would see a frame-rate
change (i.e., the next frame being significantly longer than previous
ones). After this change, VideoFrameReleaseTimeHelper is notified of
all frame PTS values, so it can retain sync in this case.
This change also propagates onStarted and onPositionReset to the helper.
This paves the way for decoupling frame-rate estimation from release
adjustment sync. Note that currently, loss of sync effectively resets
both. This is unnecessary. For example, if the renderer is paused and
later resumed, then release adjustment sync needs to be reset, but any
frame-rate estimate we have is still valid.

RunnableFutureTask is not reusable. Trying to reuse it meant that a
failure in one doWork() call would cause subsequent download() calls
to (a) not block until the runnable has finished executing (does not
apply when using a direct executor), and (b) throw the same failure
as thrown from the first doWork() call.
This could cause #8078 if the initial failure occurred before the
content length was resolved. Retries are not blocked on their work
completing due to (a), and the download would be marked as failed due
to (b). The work itself could then resolve the content length, which
causes the stack trace in this issue.

Background:
1. When the player has multiple audio renderers, by default they share a
single AudioSink.
2. When any new renderer is enabled, all disabled renderers are reset
prior to the new renderer being enabled. This is to give them a chance
to free up resources in case the renderer being enabled needs them. These
reset calls are expected to be no-ops for renderers that have never been
enabled.
The issue:
The problematic case arises when there are two audio renderers and a third
renderer (e.g., text) is being enabled. In this case, the disabled audio
renderer's reset call ends up resetting the AudioSink that's shared with the
enabled audio renderer. The enabled audio renderer is then unable to make
progress, causing playback to freeze.
This is a minimal fix that directly prevents the mentioned issue. There are
multiple follow-ups that would probably make sense:
1. Having ExoPlayerImplInternal track which renderers need to be reset, and
only resetting those renderers rather than all that are disabled. This
seems like a good thing to do regardless, rather than relying on those
calls being no-ops.
2. If we want to continue sharing AudioSink, we need to formalize this much
better and make sure we have good test coverage. Messages like
MSG_SET_VOLUME are also delivered to the AudioSink multiple times via
each of the renderers, which works currently because DefaultAudioSink
no-ops all but the first call in each case. This is pretty fragile though!

Add experimental method to synchronize MediaCodec interactions

To check what is safely possible we keep track of the live offset
corresponding to the buffered duration and only deecrease the
target offset to a safe margin from the buffered duration.

Add more MediaCodec methods to MediaCodedAdapter so that renderers

PiperOrigin-RevId: 341023452
- This change removes the last piece of logic that could cause deferred
codec release (i.e., where the decision to release was made in
processEndOfStream rather than in onInputFormatChanged.
- After this change, whether the codec will be released as a result of
a format change is always established in onInputFormatChanged.
PiperOrigin-RevId: 341012403
This fixes a case where updateCodecOperatingRate would configure
the decoder to be drained and then released, only for
onInputFormatChanged to override the drain action with something
else.
We've not seen any reports of this issue, which suggests that either
it's OK to not release the decoder in such cases, or that the
case doesn't happen very often. I suspect that it's both, but let's
restore the intended behaviour for now.

This information is already available in the MappingTrackSelector,
but not currently forwarded to the TrackSelection.Factory.

In a later change, the AdPlaybackState will include the playing adsId (set by
the AdsLoader) and the ads loader will use this to determine what ad
information is associated with the playing/next periods, to allow loading ads
in playlists.
Apps can continue to pass just a URI for an ad tag with their MediaItem, in
which case the associated playlist will request that ad tag just and the same
state will be used for all occurrences of the ad tag.
This change has breaking changes to the AdsLoader interface and removes
deprecated ways of passing the ad tag, as it's very likely to go into a major
release anyway and not needing to handle the deprecated cases simplifies
ImaAdsLoader.

By default methods File.makeDir() and File.makeDirs() can return 'false' if file aleady exists or can not be created. Such silent ignore of the situation propagates misbehavior to the caller: CacheDataSink#173 : new FileOutputStream(file). And then it throws not correct exception type 'FileNotFoundException'. While correct exception should be 'no space left on the device'.
This can be fixed only with 'Files.createDirectories()' method that throws correct exception type.
1. Move logic to decide to re-initialize the codec rather than using
MediaCodec.setMediaDrmSession if (a) PlayReady is in use, and (b)
the new session is still provisioning. This would previously have
happened asynchronously after an input format change, after the
decoder has subsequently been flushed. After this change the logic
executes synchronously when the input format changes. This helps
with the ref'd bug, since we want to propagate reasons for codec
re-initialization through inputFormatChanged events.
2. Whilst moving the logic for re-initialization if PlayReady is
being used, I fixed a bug that would occur when switching from
[PlayReady --> non-PlayReady]. Re-use doesn't work in this case.
The old logic only checked for the [Something --> PlayReady] case.
3. Remove pointless codec flush if updating the DRM session having
not queued anything to the codec.

- I don't think the session recovering later would work, because

This avoids confusion that currently exists between "operating rate"

We currently implicitly rely on the internal playback thread to not send

We have a workaround for uneven sample stream durarions in playlists that
assumes a renderer allows playback if it's reading ahead or waiting for
the next stream.
652c2f9c18 changed this logic to no longer require to
wait until the next stream is prepared due to a change in how we advance
media periods in the queue. However, the code falsely still requires the
next stream to exist (even if it's not prepared). This can cause a stuck
buffering state when the difference in the duration of the streams is more
than what we buffer ahead because we never create the next stream in such
a case.
Note: DefaultMediaClock.shouldUseStandaloneClock has roughly the same logic
and also doesn't require the next stream to be present.
Also fix a test that seemed to rely on this stuck buffering case to test
stuck buffering detection. Changed the test to not read the end of stream
to ensure it runs into the desired stuck buffering case.

Without this patch, playback would be frozen indefinitely
until the user manually pauses and unpauses it.
This has the side effect of disabling offload until

As an audio server crash is considered very
infrequent, especially in stable conditions like
an audio only playback, it is unlikely that disabling
offload is an issue.

This test is intended to check that DefaultLoadControl will cause

case that its target buffer size is reached and playback still

on some setups an OOM actually ends up happening before this much
memory is allocated.
This change makes the target buffer size much smaller to avoid the
