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.

We currently keep the sequence number if we don't reset the position. However,
the sequence number should be kept if we don't reset the state. Otherwise

- When in STATE_SEEK with targetGranule==0, seeking would exit
without checking that the input was positioned at the correct
place.
- Seeking could fail due to trying to read beyond the end of the

that occurs after the binary search has sufficiently converged.

These values can easily default to the empty track group and the empty

A previous change switched to calculation of the bitrate based on the
first MPEG audio header in the stream. This had the effect of fixing
seeking to be consistent with playing from the start for streams where
every frame has the same padding value, but broke streams where the
encoder (correctly) modifies the padding value to match the declared
bitrate in the header.

DefaultMediaClock has currently two non-ideal behaviours:
1. One part of checking if it should use the renderer clock is checking whether
the associated renderer finished reading its stream. This only makes sense
if the renderer isn't already reading ahead into the next period. This can
be solved by forwarding if we are reading ahead to the sync command.
2. When switching from stand-alone to renderer clock we assume they are
exactly at the same position. This is true in theory, but in practise there
may be small differences due to the different natures of these clocks. To
prevent jumping backwards in time, we can temporarily stop the stand-alone
clock and only switch once the renderer clock reached the same position.
PiperOrigin-RevId: 260690468
Some variables were defined although they are the default and other things
were set-up in a non-sensible way, e.g. asserting that audio is selected

1. Using the Locale on API<21 doesn't make any sense because it's a no-op
anyway. Slightly restructured the code to avoid that.
2. API<21 often reports languages with non-standard underscores instead of

3. Some invalid language tags on API>21 get normalized to "und". Use original
tag in such a case.

2-letter codes (ISO 639-1) are the standard Android normalization and thus we
should prefer them to 3-letter codes (although both are technically allowed
according the BCP47).
This helps in two ways:
1. It simplifies app interaction with our normalized language codes as the
Locale class makes it easy to convert a 2-letter to a 3-letter code but
not the other way round.
2. It better normalizes codes on API<21 where we previously had issues with
language+country codes (see tests).
3. It allows us to normalize both ISO 639-2/T and ISO 639-2/B codes to the same
language.

If we use the default start position, we currently resolve it immediately
even if we need to play an ad first, and later try to project forward again
if we believe that the default start position should be used.
This causes problems if a specific start position is set and the later
projection after the preroll ad shouldn't take place.
The problem is solved by keeping the content position as TIME_UNSET (= default
position) if an ad needs to be played first. The content after the ad can
then be resolved to its current default position if needed.

This resolves some naming confusion that previously existed
as a result of DownloadThread also being used for removals.
Some related variables (e.g. activeDownloadCount) would refer

This change renames those that refer to both to use "task"
terminology.
This change also includes minor test edits.

- Listener based reporting of progress allows the content length

Currently SimpleCache will touch cache spans whenever it reads
from them. With legacy SimpleCache setups this involves a potentially
expensive file rename. With new SimpleCache setups it involves
a more efficient but still non-free database write.
For offline use cases, and more generally any use case where the
eviction policy doesn't use last access timestamps, touching is
not useful. This change allows the evictor to specify whether it
needs cache spans to be touched or not. SimpleCache will only touch
spans if the evictor requires it.
Note: There is a potential change in behavior in cases where a
cache uses an evictor that doesn't need cache spans to be touched,
but then later switches to an evictor that does. The new evictor
may temporarily make sub-optimal eviction decisions as a result.
I think this is a very fair trade-off, since this scenario is
unlikely to occur much, if at all, in practice, and even if it
does occur the result isn't that bad.

Non-trivial download state transitions are currently split across

The position should be subtracted from the total content length

It's a transient state whose only use is when passing a removed
download to onDownloadStateChanged. It's a bit strange to have it
as a proper state, since we end up asserting that it's an invalid
value in other places.
This change adds an explicit onDownloadRemoved, which allows
removal of the transient STATE_REMOVED, related assertions, and
uncertainty when dealing with an @State variable whether it's
necessary to handle it being STATE_REMOVED.

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.

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.

The flag in ExoPlayer.prepare is documented as keeping the current window

This requires to prepare the media source and the periods in a small helper similar

The way it is currently, it's very unclear that an operation on the

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

The combination of pre-16 API levels accounting for ~0.5% of the device

We need to support serialization to/from an SQLite table. The
model of passing something around for each class to write into

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.

Calls to File.length() can be O(N) where N is the number of files

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

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.
