Numerical lines conceptually map to a grid of lines in the viewport,
with the Cue text lines being aligned to one of the viewport lines.
It doesn't make sense to position a single-line cue differently based
on lineAnchor when it's expected to 'snap' to a particular line on the
viewport grid. So we redefine the position to be in terms of the cue
lines rather than the bounds of the cue box.
It's also not possible to always handle ANCHOR_TYPE_MIDDLE when
lineType=NUMBER (as it relies on the number of lines in the cue being
odd), so it's easier to ignore lineAnchor completely.

The IMA SDK now preloads postrolls which is great as we no longer need
to rely on detecting buffering at the end of the stream to trigger
playing postrolls.
Add in the required logic to detect the period transition to playing
the postroll.

We currently get float ad cue points from IMA, but store these as
longs in microseconds. The cast from double to long would take the
floor of the value, which could lead to stored ad cue points being
off-by-one. Use Math.round to avoid this.
ImaAdsLoader also has code to map a double AdPodInfo position (which
should match a cue point) onto the corresponding ad group index by
searching the long ad cue points. Match the calculation used where we
map float cue points, including narrowing the position to a float
first to avoid regressions if IMA SDK behavior changes to represent
positions in more than float precision later, and also remove the
requirement that the ad positions match exactly as a defensive
measure.

After an ad pod coming up has preloaded, if the user seeks before it
plays we get pauseAd/stopAd called for that ad pod. Also, the ad will
not load again. Work around this unexpected behavior by handling
pauseAd/stopAd and discarding the ad.
In future, it's likely that the IMA SDK will stop calling those
methods, and will loadAd again for the preloaded ad that was
unexpectedly discarded. This change should be compatible with that,
because the ad won't be discarded any more due to not calling stopAd.
Issue: #7492
PiperOrigin-RevId: 316873699
Ads can appear due to asynchronous ad tag requests completing after
earlier ads in a pod have loaded, so remove the requirement that the
ad count can't change. The MediaPeriodQueue should handling discarding
buffered content if an ad appears before already buffered content, so
I think this case is actually handled correctly by the core player
already.
Also remove the requirement that an ad URI can't change. This is a
defensive measure for now, but it's likely that a later fix in the IMA
SDK for an issue where loadAd is not called after preloading then
seeking before a preloaded ad plays will result in loadAd being called
more than once, and I think it's possible that the second call to
loadAd may have a different URI. Because the ad URI should only change
after an intermediate seek to another MediaPeriod, there shouldn't be
any problems with buffered data not getting discarded.
Issue: #7477

The release() method was added in the recent IMA API changes for
preloading and now 'collides' with the ExoPlayer AdsLoader release
method. This led to all ads completing being treated as a call to
completely release the ads loader, which meant that the ad playback
state was not updated on resuming after all ads had completed, which
in turn led to playback getting stuck buffering on returning from the
background after all ads played.
Move the IMA callbacks into an inner class to avoid this.

We haven't seen it used anywhere in practice. It's a niche feature not
supported by any other extractors, and is one of the very few things
stopping us from simplifying MediaSource implementations to not set the
decodeOnly sample flag. This is a simplification that we want to make,
since the current mechanism doesn't work properly for cases where a
downstream decoder adjusts the buffer presentation timestamps so that
they're different on the output side than on the input side.

Previously if the AudioCapabilities reported that an encoding/channel count was
supported, DefaultAudioSink could try to play it via passthrough. However,
DefaultAudioSink does not support passthrough of every possible format (for
example, it's likely that AAC passthrough does not work given it's never been
tested and recent GitHub issues indicate that trying to use it leads to no
audio being played).
Add additional checks to make sure the encoding is in the list of encodings that
are known to work with passthrough in DefaultAudioSink.

EventTime contains information about when an event happened and where
it belongs to. Both places can be fully described using timeline, window
index, media period id and position.
Right now, only the information for where the event belongs to is fully
contained in EventTime, whereas the time when the event happened only has
the position, and none of the other information (timeline, window, period).
This change adds the missing information, so that the EventTime can easily
be used without having access to the Player. This also ensures Event
metadata is self-contained and can be stored and reused later.

Some player setup steps that are likely to be only done once
should be moved into the Builder so that player setup can use

frameworks) and setters can't be used due to threading restrictions.

We keep an index hint for the next pending player message. This hint

This change makes sure to only use the hint locally in one method so

suffix to the variable name to make it clearer that it's just a hint and
there are no guarantees this index actually exists anymore.

Steps 4-10 of https://www.w3.org/TR/webvtt1/#cue-computed-line
This part is harder to fit into our code structure because it depends on
how many cues are simultaneously visible - so it has to go in
WebvttSubtitle not WebvttCueParser (which only deals with individual
cues in isolation).
This removes the `isNormal()` method that was trying to approximate
the correct behaviour.

When ClippingMediaPeriod first tried to read a buffer, if its end
position was before the end of the stream and it was buffered to its end
position, it would sometimes erroneously signal end-of-stream for
protected content because the sample queue might be waiting for DRM keys
at this point.
Work around the issue temporarily by signaling this specific case back
to ClippingMediaPeriod via the DecoderInputBuffer.
There will likely be a cleaner fix as a result of adding support for
dynamic clip end points in the future, at which point this can be
reverted.

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.
