This generalizes our "does file still exist" check to also check
that the file is the expected length. If it's not, we don't trust
it. This avoids infinite recursion in CacheDataSource if a cache
file is truncated underneath the cache.

Implementations of ForwardingTimeline may override any of the two variants of
this method. We need to ensure that the customized override is always called.

Add back the deprecated method and make it final to forward to the
non-deprecated method in all cases for ForwardingTimelines.

The last selection criteria is the audio bitrate to prefer higher-quality
streams. We shouldn't apply this criterium though if the languages of the
tracks are different.

If the app seeks after we get an ads manager but before the player exposes the
timeline with ads, we would end up expecting to play a preroll even after the
seek request arrived. This caused the player to get stuck.

Wait until a non-empty timeline has been exposed via onTimelineChanged before
initializing IMA (at which point it can start polling the player position). Seek
requests are not handled while an ad is playing.

The implementation can't work properly unless these methods are called by
subclasses, so annotate them to require calling the super implementation when
overriding.

The error is closely related to the playback state IDLE and should be updated
in sync with the state to prevent unexpected event ordering and/or keeping the
error after re-preparation.

Update comment to indicate correct int value of "FLAG_ALLOW_CACHE_FRAGMENTATION" in ExoPlayer2 upstream DataSpec

Currently the value of FLAG_ALLOW_CACHE_FRAGMENTATION is defined as "1 << 4" but commented as "8". Either the value of FLAG_ALLOW_CACHE_FRAGMENTATION should be "1 << 3", or the comment should be 16. Here I am modifying the comment since it does not affect any current behavior.

The app is able to pass a more specialized array type, so the Arrays.copyOf call
produces an array into which it's not valid to store arbitrary AudioProcessors.

Create a new array and copy into it to avoid this problem.

Any seek before the first timeline becomes available will result in a NPE.
Change it to handle that case gracefully.

This situation happens if the first chunk to load is already behind the end
of the stream. In this case, the preparation never completes because
HlsSampleStreamWrapper gets stuck in a prepared=false and loadingFinished=true
state.

Gracefully handle this situation by attempting to load the last chunk if still
unprepared to ensure that track information is obtained as far as possible.
Otherwise, it wouldn't be possible to play anything even when seeking back.

Extract supplemental data from block additions in WebM/Matroska.

Allow storing supplemental data alongside samples in the SampleQueue and write
it as a separate field in DecoderInputBuffers.

Handle supplemental data in the VP9 extension by propagating it to the output
buffer.

Handle supplemental data for HDR10+ in MediaCodecVideoRenderer by passing it to
MediaCodec.setParameters, if supported by the component.

AdsMediaSource posts AdsLoader.start to the main thread during preparation, but
the app may call AdsLoader.setPlayer(null) before it actually runs (e.g., if
initializing then quickly backgrounding the player).

This is valid usage of the API so handle this case instead of asserting. Because
not calling setPlayer at all is a pitfall of the API, track whether setPlayer
has been called and still assert that in AdsLoader.start.

There is no point in having this parameter as the tag should always be a single
immutable object instantiated at the time the Timeline is created or earlier.

So there is no preformance benefit and it's error-prone in case people
forget to set setTag=true.

This solves various issues around event association for buffering and
error throwing around period discontinuities.

The main changes are:
 - Logic around being "ready" at the end of a period no longer checks if the
   next period is prepared.
 - Advancing the playing period no longer checks if the next one is prepared.
 - Prepare errors are always thrown for the playing period.

This changes the semantics and assumptions about the "playing" period:
 1. The playing period can no longer assumed to be prepared.
 2. We no longer have a case where the queue is non-empty and the playing or
    reading periods are unassigned (=null).
Most other code changes ensure that these changed assumptions are handled.

Most users are likely to be only interested in the playlist items. So put the
Window definition first and explicitly mention that this is a playlist

I removed the buffer.flip() call because it seems incompatible with the way MetadataRenderer deals with the Stream - it calls flip() itself on line 126. Tests fail with flip() here, and pass without it...

The builder takes renderers instead of using a factory.

PiperOrigin-RevId: 263354003

The current ExoPlayerFactory is growing too big and usage becomes increasingly
complicated because it's not possible to set individual components without
specifying many other defaults.

Adding new builder classes makes building easier and more future-proof.

entries are used in .equals(), so it's good to have them printed in toString() too (for test failures) and it makes logging easier too.

The current max video buffer is 13MB which is too small for high quality
streams and doesn't allow the DefaultLoadControl to buffer up to its default
max buffer time of 50 seconds.

class.
