We aim to have the same media item instance published in the timeline that is passed to the createMediaSource(mediaItem) method. This means when the manifest uri is manually replaced by a developer, the media item published in the next timeline update is still the same.
Note: This leads to the fact that the manifest published in that timeline is loaded from a different URI than the URI of the media item in the same timeline.

- The new CacheWriter is simplified somewhat
- Blocking on PriorityTaskManager.proceed is moved out of
CacheWriter and into the Downloader tasks. This is because
we want to shift only the caching parts of the Downloaders
onto their Executors, whilst keeping the blocking parts on
the main Downloader threads. Else we can end up "using"
the Executor threads indefinitely whilst they're blocked.

Sometimes it's useful to be able to block until something on some other thread
"really has finished". This will be needed for moving caching operations onto
the executor in Downloader implementations, since we need to guarantee that
Downloader.download doesn't return until it's no longer modifying the
underlying cache.
One solution to this is of course just to not interrupt the thread that's
blocking on the condition variable, but there are cases where you do need to do
this in case the thread is at some other point in its execution. This is true
for Downloader implementations, where the Download.download thread will also
be blocking on PriorityTaskManager.proceed. Arranging to conditionally
interrupt the thread based on where it's got to is probably possible, but seems
complicated and error prone.

Previously if the AudioCapabilities reported that an encoding/channel count was

DefaultAudioSink does not support passthrough of every possible format (for

tested and recent GitHub issues indicate that trying to use it leads to no
audio being played).
Add additional checks to make sure the encoding is in the list of encodings that
are known to work with passthrough in DefaultAudioSink.

EventTime contains information about when an event happened and where
it belongs to. Both places can be fully described using timeline, window
index, media period id and position.
Right now, only the information for where the event belongs to is fully
contained in EventTime, whereas the time when the event happened only has
the position, and none of the other information (timeline, window, period).
This change adds the missing information, so that the EventTime can easily
be used without having access to the Player. This also ensures Event
metadata is self-contained and can be stored and reused later.

This is useful for merging the FFmpeg video support pull request,

the tts:textAlign properties from the source data (currently this
information is stripped when we remove all span styling). I think this

Assert incoming buffers are little endian in the DefaultAudioSink.

PiperOrigin-RevId: 310889382
When operating the MediaCodec in asynchronous mode, we are seeing
NPEs raised from the DefaultAudioSink because output buffers are pushed
to the DefaultAudioSink with the DefaultAudioSink not configured yet.
This is possible to happen if an output buffer is passed with
MediaCodecAudioRenderer.processOutputBuffer() before an output format
change.
One possible code path to trigger this is when an output format change
is pending and we flush MediaCodec (e.g. for a seek): the callback is
waiting in the looper's queue but we ignore all currently queued
callbacks after a flush().
This commit checks for a pending output format change during a flush():
if one exists, and the next MediaCodec output callback right after the
flush() is an output buffer (and not a new output format), then the
pending output format is propagated first.
The only adapter that needs to change is the
AsynchronousMediaCodecAdapter which previsouly deleted all pending
callbacks immediately on flush(). The AsynchronousMediaCodecAdapter now
needs to also handle every enqueued callback in order to identify is
there's a pending output format change.
Testing: added unit tests for the new code. I have verified that if we
pass an output buffer to the audio renderer before the output format, it
will result on the specific NPE, but I cannot reproduce the base
scenario (an output format change is pending when flushing) on a real
device because we can't know if an output format is indeed pending.

Fixes AsynchronousMediaCodecBufferEnqueuerTest broken tests by

it seems to work with the current robolectric shadow MediaCodec. This is
at the moment preferred compared to making the test more complicated.

Currently, DashMediaPeriod only takes into account as CEA-608 accessibility tags as embedded
closed captions tracks CEA-608. CEA-708 closed captions format is parsed when is present on
its own AdaptationSet, but not when is embedded as an accessibility tag in a video AdaptaticonSet.
Embedded CEA-708 support is added by parsing accessibility tags like the example below:
<Accessibility schemeIdUri="urn:scte:dash:cc:cea-708:2015" value="1=lang:eng;2=lang:deu"/>
<Accessibility schemeIdUri="urn:scte:dash:cc:cea-708:2015" value="1=lang:eng;2=lang:eng,war:1,er:1"/>
so it creates a new CEA-708 track for accessibility tags with schemeIdUri = urn:scte:dash:cc:cea-708:2015
and extract accessibilityChannel and language from value attribute.

With sample prepare (non-chunkless) the `Format` object in the TrackGroup is derived from the data in the stream and data in the manifest. This change includes the roleFlags from the HLS manifest parse in the final derived format.
DownloadManager doesn't know enough about the Downloader implementations to
know that interrupting the thread is the right thing to do. In particular,
if a Downloader implementation wants to delegate work to additional worker
threads, then it will probably not want its main thread to be interrupted
on cancelation. Instead, it will want to cancel/interrupt its worker threads,
and keep its main thread blocked until work on those worker threads has
stopped (download() must not return whilst the Downloader is still touching
the cache).
This change moves control over what happens to the individual Downloader
implementations.

- Stop throwing InterruptedException from CacheUtil. When a CacheUtil operation
throws or returns, the caller should always check its own state to determine
whether they canceled the operation. If a caller is trying to catch
InterruptedException separately to IOException to do something different in
that case, they're probably doing the wrong thing. So it's simpler, and probably
less error prone, just to throw an IOException in the case of interruption.
- Throwing InterruptedIOException is also consistent with what our Extractor and
DataSource implementations do.

The player's initial PlaylistTimeline has no ad cue points, so its first
MediaPeriodId has no nextAdGroupIndex. When the AdsMediaSource provides its
first timeline, the cue points become known. For the case where a preroll cue
point appeared, the preroll was detected due to isAd changing on the
MediaPeriodId. For the case where a midroll/postroll cue point appeared, the
MediaPeriodId was actually treated as the same, which leads to keeping the
unclipped original MediaPeriod.
Fix this behavior by checking for nextAdGroupIndex becoming set or decreasing.

DownloadRunner.getDownloader was creating Downloader instances before the actual

A previous change added these getters to CacheDataSource, but it can
also be useful to retrieve these components directly from the factory.
This is useful for tasks where we're going to need to build multiple

also need to operate directly on the same components. It's a bit more
natural to retrieve them from the factory than from an arbitrary

you create a CacheDataSource instance earlier than you would otherwise
just to use its getters, and/or create one just to use its getters and

While most ExoPlayer code parsing ByteBuffers is called with buffers in big
endian, in certain situation, buffers in little endian are used too.
MediaCodec produced ByteBuffers are in little endian, while buffers
receive from the sources are in big endian (ByteBuffer's default).
As a result, some code called from AudioSink in passthrough parsed
bytebuffer in little endian. This is not correct because those
format are specified in BigEndian.
Changing the endianness of the ByteBuffer returned from MediaCodec
would impact a lot more code that can currently be tested in the
current COVID lockdown situation.
As a result, this patch instead make the parsing code independent
of the ByteBuffer.order() set. All the code that is called from
