It's interesting WebVTT explicitly handles line & position differently
in horizontal-rl/lr and vertical-lr/rl contexts. position is always
measured from the left of the viewport, even for rtl text, but line in
vertical-rl is measured from the right of the viewport.
We don't have to make Cue match WebVTT (I can go change the WebVTT
decoding instead) but it seems a reasonable 'default' to follow.

ExoPlayer needs a codec to decide among WEBVTT and TTML decoder mimeType.
Apple describes IMSC1 in MP4 in
[RFC-8216 Section 3.6](https://tools.ietf.org/html/draft-pantos-hls-rfc8216bis-04#section-3.6).
The DASH manifest specifies the SMPTE-TT captions in the codecs in the manifest
(from W3C [TTML Profiles for Internet Media Subtitles and Captions 1.1](https://www.w3.org/TR/ttml-imsc1.1/#general-0).
DASH just doesn't require the rendition linking, but HLS does.
Apple implies the CODECS attribute of the variant needs to be do this. That is
with SHOULD and MAY language to imply the codec to use for it in the
[Authoring Guidelines](https://developer.apple.com/documentation/http_live_streaming/hls_authoring_specification_for_apple_devices)
This change defaults to WebVTT if no codec is specifed (same as current behavior) otherwise it picks it from the variants
referencing the media.
Without this, URL-encoding is assumed, which means ampersand-codes are
not carried through to the underlying web page correctly.

HlsSampleStreamWrapper currently calls HlsMediaChunk.init, which calls back

Selection of a passthrough codec will rarely (if ever) need to be customized, so
remove this capability from MediaCodecInfo.
Applications can still customize whether passthrough is used by overriding
MediaCodecAudioRenderer.usePassthrough, which now also checks for a passthrough
codec.

This avoids massive changes to method signatures to add throws. Also, took suggestion to make it an `IllegalStateException`.
Move the catch outside of the finally that sets `nextLoadPosition` (this allows for possible recovery by reseting the `Extractor` and `TimestampAdjuster`).
Lastly, took the suggestion to make a minimum value for the tolerance (especially usefull for very short i-Frame only segments).
CharSequence is used by Notification builders and allows to set Spannable text.
It's the base interface of the String class, so apps wouldn't be break after

- They are always listed with their canonical names
- Considering aliases means that blacklisting a decoder can end up
not actually blacklisting it, since it may still be accessible
via an alias. It also means that our decoder fallback logic can
end up falling back to a decoder that we've already tried!

This callback will be deprecated, so moving all usages to better callbacks.
Some usages are still remaining that are less straight-forward to update.

OnSeekProcessed is documented to be called as soon as all neccessary state changes
as a result of the seek have been made. As we now mask the state changes directly
when calling seekTo, we can also call this callback immediately without changing
the semantics of the method.
Our tests often use this callback as a way to wait for the internal player
to receive all pending commands and then report back. This is a special test
requirement for cases where we want to make sure no further updates happen as
a result of the player handling commands. To facilitate that, a new action is
added with a more descriptive name that achieves the same goal.

This moves the playlist API methods to the Player interface. Implementation is moved from ExoPlayerImpl to BasePlayer where possible.

This is less confusing than having audio processing functionality (e.g., playback

We currently have multiple places in ExoPlayerImpl that assign PlaybackInfo
instances and then inform listeners of all current changes. This is not ideal
because it causes multiple issues:
1. Some changes may easily be forgotten, e.g. there are clearly some checks
missing to see if isPlaying changed (e.g. in seekTo or setMediaSources)
2. Some callbacks didn't check if the value actually changed before sending
the callback (e.g. for the timeline change in setMediaSources - if the
timeline is still the same, we shouldn't send a onTimelineChanged event).
3. Having multiple callbacks in a single Runnable changes the order of
listener invocations slightly: Currently all events for one listener will
be send first before moving to the next listener. It should however send
a single event to all listeners first before moving to the next event.
All these issues can be solved by always using updatePlaybackInfo and never
assigning playbackInfo directly in another place.
Some tests needed to be updated as well because of issues (2) and (3). Also
added a new test to cover issue (1).

If MaskingMediaSource masks a multi-window media source, it may be that a period
is removed while we are using an initial unprepared masking MediaPeriod. That
means it's not guaranteed that a timeline update still contains our
unpreparedMaskingMediaPeriod and we should ignore timeline updates where the
period is no longer present because the it will be removed anyway.

We have two known scenarios where the app could create an OOM error and
we want to handle it gracefully:
1. The app continues to allocate memory but doesn't make any progress
in the buffered position. OOM should be prevented by the default
load control and it should eventually throw an exception.
2. An extractor tries to allocate a large amount of memory on the
Loader thread based on information it read in faulty media files.
In this case we should attempt to play remaining media and then
throw an exception.
Both cases are already handled correctly, but we don't have any tests
ensuring that we don't introduce regressions.
PiperOrigin-RevId: 301585700
This removes a workaround that always continues buffering and instead
detects if the LoadControl returns false even though we don't have
any buffer. If enabled by a flag, this condition throws an exception.
PiperOrigin-RevId: 301584239
The restriction that these classes only work with SimpleDecoders
is unnecessary. An FfmpegVideoRenderer will not be able to use a
SimpleDecoder, because the SimpleDecoder assumption that each input
buffer can be decoded immediately into a corresponding output is
not true for all video codecs that Ffmpeg supports (e.g., H264 does
not have this property). Generalizing SimpleDecoderVideoRenderer to
DecoderVideoRenderer will allow FfmpegVideoRenderer to still use
the base class, without having to use a SimpleDecoder.
This is a preliminary change toward being able to merge a version
of https://github.com/google/ExoPlayer/pull/7079.

The test is flkay (2/1000 runs) because the decoder initialization
before and after the seek are not perfectly deterministic. I couldn't
find a way to make them deterministic, so slightly chaning the test
setup instead. The test setup change doesn't affect the scenario being
tested.

When no tracks are selected (or only tracks of unknown type), the

The assertion about the expected formats doesn't really belong in a
fake, the assertions should be closer to the test method.
This gets in the way when I try and write a new test in
AnalyticsCollectorTest that doesn't use the expected, constant Format
(because i want to specify drmInitData) - but changing the expected
Format is tricky because it's hard-coded into the FakeVideoRenderer
inner class.
I replaced the assertion in FakeRenderer with assertions in test
methods that used to assert on the format count.

Without this change there's confusing behaviour if you pass e.g.
AnalyticsCollector (which implements both DrmSessionEventListener and

MediaSource.addDrmEventListener.
Also add some tests for MediaSourceEventDispatcher.

This prevents OOM errors for high bitrate streams that attempt to fill

After this change users of ExoPlayerImpl and SimpleExoPlayer can use the media item base playlist API which converts the media item to a media source.

We currently have the following logic to update renderers during
period transitions:
1. Wait for the currently reading period to finish reading all its
streams.
a. Advance reading period.
b. Set all streams that can't be replaced to final.
c. If streams can be replaced, replace them now.
2. Wait until playback position reaches the transition point
a. Disable all unneeded renderers (or those that need
re-enabling).
b. Advance playing period.
c. Enable all new renderers (i.e. all except the ones where
we replaced streams directly in step 1c.
This logic causes delays because steps 2a and 2c can easily happen
before 2b. Doing this allows a smooth transition for cases where
renderers change or where they need to be re-enabled.
The new order after this change is:
1. Wait for currently reading period to finish reading.
a. Advance reading period.
b. Set all streams that can't be replaced to final.
2. Update reading renderers iteratively.
a. If streams can be replaced, replace them asap.
b. If renderes need to be disabled, do so as soon as the
respective renderer ended.
c. Once step b is fully finished, enable or re-enable all new
renderers.
3. Wait unril playback position reaches the transition point AND
all tasks in step 2 are done (i.e. all renderers are set up for the
playing period).
a. Advance playing period.
As a nice side effect, decoder enabled and disabled events are now
always reported for the reading period, which is more consistent with
other renderer callbacks.

This list was meant to simplify some usages where we only want to
make operations on enabled renderers. However, keeping this list
up-to-date is slightly error-prone (because renderers aren't added
and removed from this list next to the corresponding enable and disable
calls) and it makes it hard to do more fine-grained changes that only
enable or disabled a single renderer at a time.
