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

This change deprecates the old one, adds a Util method to easily map back from the new

[Problem]
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
is radically decreased.
[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
provider.
[Test]
This should influence CEA608 pop-up cations only. (Not roll up).
Test various live channels with this change.
Note: Beginning of commercials tend to have PAINT-ON mode as that
is immediately showing incoming characters, not just at the end
of the line like POP-on mode.
This instantiates the renderers and extract the capabilities. None of the known
renderes incurs any overhead during instantiation.

- Enable GZIP for media playlist + encryption key chunk requests in
HLS, as we do during playback

completeness, if nothing else)
PiperOrigin-RevId: 224057139
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.

[Problem]
PAINT-ON mode is not implemented. From the compliance tests:
* RDC command has no effect except to select paint-on style.
* Next data are written directly to the display upon receipt.
* If other captioning is already on the screen, the four-row
limit is still in effect.
[Solution]
It is a rare use case, we do not support overriding characters in
existing cueBuilders as PAINT-ON would require. But several
compliance tests check if the screen is cleared when the mode
switch happens. We must keep the old captions when switching
to PAINT-ON mode

PAINT-ON mode

It's no longer guaranteed that onOutputFormatChanged will always be

Currently, MediaCodecRenderer's render loop does not have any time limit. We
always try to drain and feed as much buffers as possible. This may lead to a
pattern of feeding phase takes too much time from previous loop, which makes
the next draining phase drops all buffers, making these buffers available for
feeding all at once, and the pattern keeps repeating.
This CL adds an experimental parameter for setting a time limit. If the time
limit is exceeded, the feeding process stops even if more input could be fed.
The default behavior is unchanged

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.

- Handling EVENT_PROVISION_REQUIRED is unnecessary because we handle
it via NotProvisionedException, which was thrown on all API levels.
- Handling EVENT_KEY_EXPIRED during playback is unnecessary. All it
does is cause an error to be thrown, but an error will be thrown
anyway out of the MediaCodec when it tries to use the expired keys.
It's currently a race condition where the error gets thrown from,
where-as having it always be thrown from one place is preferable.

There are multiple subtle issues with the current implementation:
1. setOperatingRate can cause a codec initialization even if the
renderer is disabled. This is not supposed to happen.
2. If the codec is released whilst the renderer is disabled, the
renderer can instantiate a new codec using the old format when
it's enabled again, only to immediately have to reconfigure or
release it if the actual format to be played is different.
3. Codec reuse does not take into account renderer configuration.
The specific case where this is problematic is if the video
renderer is re-enabled with a different tunneling session id.
The reused codec is then not configured correctly.
Also moved availableCodecInfos reset into releaseCodec for sanity.

setSurface only sets the output surface on the codec if the
renderer is enabled or started. This was fine in the past
because the codec was always null in other states, however
the recent codec reuse work means this is no longer the case.
The output surface should always be set if the codec is
non-null. If setting the surface requires releasing the codec
instance, we should only instantiate the new instance if
enabled or started. This is in line with what onDisabled does
if flushing requires releasing the codec

For decoder reuse, we want disable() to flush the decoder. However,
if the flush needs to release the decoder for some reason, it seems
non-ideal to immediately re-initialize it. Re-initialization can
also throw ExoPlaybackException, which we don't want for disabling.
This change allows a variant of flush that wont re-initialize the
decoder if it has to be released, which will be used from disable().

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.

These two methods are meant to indicate to the track selection that it's
started or stopped being used. This is helpful to schedule background tasks
related to track selection (e.g. register network change listeners etc.).
This intention is not clearly stated in the method docs.
Also, all track selections of all prebuffered periods stay enabled in
parallel at the moment. As the whole purpose of these methods is to know
whether dynamic updates via updateSelectedTrack may happen, it's better to
only enable track selections of the current loading media period. That's
similar to how we always forward the loading track selections to the
LoadControl.
This change:
1. Improves the JavaDoc of TrackSelection.
2. Disables track selections if loading moves to another period.
3. Reenables track selection if loading moves back to a previous period.
