When an error occurs we call stopInternal, and this clears the MediaPeriodQueue,
which in turn releases media period holders and notifies that media periods have
been released. AnalyticsCollector updates its information about media periods
using the media period release events, which means that if we post the source
error after stopInternal posts its events we can't determine what media period
the source error corresponds to.
Move error notifications before calling stopInternal, so that
AnalyticsCollector's model of the media period queue contains the loading period
at the point when it handles the error.
For consistency also move the other (non-source) error notifications to match
the new ordering.

The release needs to post to the MediaSource thread and also needs to post

This is more in line with "forgetting all previous state" as documented for
resetState=True. Also only apply the current position as initial seek position
in this case.
PiperOrigin-RevId: 236623630
We currently throw if a pending seek position was valid when the user issued
it on the app thread, but can't be resolved on the playback thread because the
timeline changed in the meantime. Throwing in this case seems wrong as the
user could not have known about the issue (and the seek position was actually
valid). Also, in other cases where the currently playing period is no longer
in the new timeline, we gracefully use a subsequent period or transition to
ENDED state instead of throwing. So it seems more consistent to transition to
ENDED state as well.
PiperOrigin-RevId: 236274862
The flag in ExoPlayer.prepare is documented as keeping the current window

Previously we would get a new AudioTrack and flush all audio processors if any
AudioProcessor needed to be flushed on reconfiguration. This was problematic for
the case of TrimmingAudioProcessor because it could become active or inactive
due to transitioning to a period with gapless metadata or without it (we don't
keep it active all the time because it is wasteful to populate its end buffer
for content that is not gapless).
This change handles the case where we don't need an AudioTrack but
AudioProcessors do need to be flushed. In this case we drain all the audio
processors when next handling data then switch to the new configuration.
This avoids truncation when period transitions change whether
TrimmingAudioProcessor is active but don't require a new AudioTrack, and is also
a step towards draining the AudioTrack when transitioning between periods if we
do need a new AudioTrack.
To do this, it needs to be possible to drain any pending output data from an
AudioProcessor after it's configured to a new format, so this change makes sure
AudioProcessors allow calling playToEndOfStream and getOutput after
reconfiguration and before flush.

This requires to prepare the media source and the periods in a small helper similar
to the metadata retriever. It also gets rid of the need to have abstract protected
methods to load the manifest, to extract the track groups and to convert to stream keys,

PiperOrigin-RevId: 231385590
Converting a single track selection to stream keys is only possible if the output
is independent from other track selections being made.
This is not the case for DASH and HLS embedded track groups which should select the

track group is selected).
Also, update the test method to take a period index.

1. The method kept track of the current period index to check if the next

already detected by canKeepMediaPeriodHolder.
2. We updated the MediaPeriodIndfo twice: once in getFollowingMediaPeriodInfo

follow. The only difference is that getUpdatedMediaPeriodInfo keeps the
content position while getFollowingMediaPeriodInfo resets it. This is made more
explicit for readability.

it compared the same durations (partly due to the confusion caused by 2.)

The buffered position is currently based on the mimimum queued timestamp of

without bounds as the "buffered position" will always stay at the shorter

CacheEvictor.onStartFile currently receives a length, which is the
maximum size of the content that might be written. The LRU cache
evictor will make sure there's sufficient space for the specified
size. If the actual size of the content is unknown, CacheDataSink
passes maxCacheFileSize.
The current behavior isn't ideal. It seems valid for a developer to
specify maxCacheFileSize=Long.MAX_VALUE if they don't want any
file fragmentation in the cache. However if they then attempt to
cache something with unknown length, LRU cache will try and make
room for content of length Long.MAX_VALUE, and end up evicting the
entire cache to do so.
This change alters the logic so a length is only passed if the
actual size of the content is known. In other cases C.LENGTH_UNSET
is now passed. The LRU evictor will not evict until after the file
is committed. Note a custom LRU evictor could still opt to evict to
ensure some application specified amount of space, if that's the
desired behavior.

Problem: There is nothing in the Cache interface that enforces that
these methods are implemented by reading/writing content metadata,
however our own code (CacheDataSource) relies on this property since
it mixes use of [get|set]ContentLength and use of metadata. Using
metadata is the right approach because it minimizes the number of
index writes (e.g. it allows the redirect URI and the content length
to be committed by a single write).
Solution: Remove [get|set]ContentLength, which are redundant anyway,
and use metadata everywhere. Also expose the keys being used through
the public API; there's no particular reason why they shouldn't be.
We previously had an API for getting and setting content length, but
no API for getting and setting redirect uri.

As the alignment of each lineas are calculated individually, the
artificially introduced CENTER and RIGHT alignments can be mixed
with each other and with the default LEFT alignment. The mixed results
look worse than just using the original DEFAULT, and the readability

[Solution]
Pre-calculate the alignment for each line, and use the leftmost of them
for all lines. The intention of caption provider could be different, but
the worst case scenario is that we revert back everything to LEFT
alignment that is the only option in the CEA608 standard so we
show everything at the exact location it is set in the content.
The readability is never worse than the one given by the content

We currently default to not caching data if the content length
cannot be resolved once the DataSource has been open. The
reason for this is to avoid caching progressive live streams.
By doing this we were accidentally not caching in other places
where caching is possible, such as DASH/SS/HLS segments during
playback if the server doesn't include a Content-Length header.
Also HLS encryption key chunks, which were very unlikely to be
cached during playback because we explicitly set FLAG_ALLOW_GZIP
(which normally stops content length from resolving) without
setting FLAG_ALLOW_CACHING_UNKNOWN_LENGTH.
It seems like a good idea to flip the default at this point,
and explicitly disable caching in the one case where we want
that to happen.
