When calling releaseSource(), all pending messages will be removed. That means
that all action-on-completion callbacks which are somewhere in flight are
just dropped without being called. This change adds code to keep track of the
current state of each callback to allow all of them being called when the
source is released.

We can keep the reading media period and continue playing if we haven't read
beyond the new duration. Otherwise, we can keep the period, but need to reset
the renderers as we already read too far.
PiperOrigin-RevId: 231406252
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,
as this can now be handled by the media period.

The way it is currently, it's very unclear that an operation on the
version table will correctly belong to a transaction in code such as
this, taken from DefaultDownloadIndex:
writableDatabase.beginTransaction();
try {
writableDatabase.execSQL(...);
versionTable.setVersion(...);
writableDatabase.setTransactionSuccessful();
} finally {
writableDatabase.endTransaction();
}
This change explicitly passes the database, to make it obvious that
the operation will really go into the same transaction:
writableDatabase.beginTransaction();
try {
writableDatabase.execSQL(....);
VersionTable.setVersion(writableDatabase, ...);
writableDatabase.setTransactionSuccessful();
} finally {
writableDatabase.endTransaction();
}

If are allowing changing durations of periods, we shouldn't use the end position
of clipped content as part of the id as it may change. This change moves the end
position back to MediaPeriodInfo and adds the next ad group index to the id
instead to ensure we still have unique ids for all content parts.

The combination of pre-16 API levels accounting for ~0.5% of the device
population, and that the most important components in ExoPlayer (e.g.
the MediaCodec renderers) have always required API level 16, mean it's
very unlikely this will negatively impact on anyone.

We need to support serialization to/from an SQLite table. The
model of passing something around for each class to write into
doesn't work well for SQL, and it would be messy to have two
different structural designs for serialization. This change
centralizes the logic in CachedContentIndex, where a centralized
SQL based version can more easily sit alongside it.

1. The method kept track of the current period index to check if the next
period is still in the correct period. This is unneccessary since we no longer
use the period index but the actual uid in MediaPeriodId and mismatches are
already detected by canKeepMediaPeriodHolder.
2. We updated the MediaPeriodIndfo twice: once in getFollowingMediaPeriodInfo
and once in getUpdatedMediaPeriodInfo. That's confusing and difficult to
follow. The only difference is that getUpdatedMediaPeriodInfo keeps the
content position while getFollowingMediaPeriodInfo resets it. This is made more
explicit for readability.
3. The durations compatibility check for all following periods was broken as
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
all AV tracks. If the tracks have unequal lengths, one track continues loading
without bounds as the "buffered position" will always stay at the shorter
track's duration.
This change adds an optional buffer flag to mark the last sample of the
stream. This is set in the Mp4Extractor only so far. ExtractorMediaSource
uses this flag to ignore AV streams in the buffered duration calculation if
they already finished loading.

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.

We currently have two factory methods where it is completely unclear which one needs
to be overridden.
This change deprecates the old one, adds a Util method to easily map back from the new

our code.
PiperOrigin-RevId: 224303560
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.

Before this change, the player state would be STATE_ENDED then
STATE_BUFFERING (when the postroll ad was marked as played) then
STATE_ENDED again.
Queueing a final content media period with start point equal to
the content duration after a postroll ensures that the player
state doesn't change to STATE_ENDED transiently.
Switch from using C.TIME_END_OF_SOURCE to C.TIME_UNSET for media
periods that should not have an end point and are not followed
by an ad.
Content media periods before postrolls have end position
C.TIME_END_OF_SOURCE. If the postroll ad loads, its content
position is set to the content duration, which should be known
at the point of loading the postroll, then a final 'empty'
content media period with start position equal to its duration
is queued. If the postroll fails to load, this empty content
media period is queued up directly after the preceding content
media period.

If we prepare a deferred media period before the actual timeline is available,
we either prepare with position zero (= the default) or with a non-zero
initial seek position.
So far, the zero (default) position got replaced by the actual default position
(including any potential non-zero window offset) when the timeline became known.
However, a non-zero initial seek position was not corrected by the non-zero
window offset. This is fixed by this change.
Related to that, we always assumed that the deferred media period will the
first period in the actual timeline. This is not true if we prepare with an
offset (either because of an initial seek position or because of a default
window position). So, we also determine the actual first period when the
timeline becomes known.
