The methods in ExoPlayerImpl and MediaControllerImplBase that determine
the new PlayerInfo/PlaybackInfo currently have a hard-to-reason-about
setup where the method generating the new info accesses other methods
that rely on the existing class field instead of working with the
passed in PlayerInfo/PlaybackInfo. This prevents reuse of the util
methods (e.g. for replaceMediaItems) because they access potentially
stale state.
This change untangles these methods a bit by making the util methods
either static or at least ensure that they don't rely on existing
class fields of PlayerInfo/PlaybackInfo. Overall, the change is a
complete no-op.

In terms of MCVR with a `VideoRendererEventListener`, the video size is set to
0/0 right after `onVideoDisabled()` is called and is set to the actual size as
soon as the video size is known after 'onVideoEnabled()`.
For ExoPlayer and in terms of the `Player` interface, `Player.getVideoSize()`
returns a video size of 0/0 when `Player.getCurrentTracks()` does not support
`C.TRACK_TYPE_VIDEO`. This is ensured by the masking behavior of
`ExoPlayerImpl` that sets an empty track selection result when the playing
period changes due to a seek or timeline removal.
When transitioning playback from a video media item to the next, or when
seeking within the same video media item, the renderer is not disabled.

Tone-mapping an HDR video with MediaCodec on sm-s908u1 was timing out.
The reason for that is that the decoder was dropping frames, and the

sm-f936b. Removed the model check as the bug is probably present on more

Adding items to an empty playlist is slightly different from adding
items to a non-empty playlist, because the former usually requires to
handle a change in the current item, position and playback state,
while the latter is not expected to affect the current item, position
or state.
The current ExoPlayer and SimpleBasePlayer code doesn't account for
this difference, leading to inconsistent behavior between
setMediaItem(s) and addMediaItem(s) when called on an empty playlist.

In addition to the changes in 3a5c4277a7
This change essentially reverts 30e5bc9837 (Merged Jul 2022).
From this CL on, `VideoFrameProcessor` takes in non-offset, monotonically
increasing timestamps. For example, with one 5s and one 10s video,
- `VideoFrameProcessor`'s input should start from 0
- On switching to the second video (10s), the timestamp of the first frame in
the second video should be at 5s.
In ExoPlayer however, `streamOffset` is managed differently and thus needs
correction before sending the frames to `VideoFrameProcessor`:
- The timestamp of the first video is offset by a large int, so the first frame
of the first media item has timestamp (assuming) 10000000000000000
- The last frame of the first media item has 10000005000000000
- At this point the stream off set is updated to 10000005000000000
- The pts of the first frame of the second video starts from 0 again.

There is a race with the ad period preparation having completed
and `onDownstreamFormatChanged` being called when a live stream
is joined in an ad period. In this case the stream event metadata
of the period is immediately emitted and causing an ad media period

being prepared (1 out of 4).
Using an `isPrepared` flag makes sure we don't hand out the media
period to early in `getMediaPeriodForEvent`.

The `DashMediaSource` wrongly added an offset to the media times set
to the `MediaLoadData`. With this the `startTimeMS` and `endTimeMs`
don't represent the positions in the period but in the stream.
`DashMediaSource` was the only call site that was setting the offset
to a non-zero value. So if we are using 0 for the `DashMediaSource`
as well, the offset is redundant and we can remove it everywhere.

When MediaCodecRenderer is given an empty sample stream, it puts
its output format change tracking in a bad state where we never
process future stream changes because we are waiting for a sample
that doesn't exist.
We can fix this by:
- Looping the pending output stream changes to see if we processed
more than one change at once (this fixes the tracking for empty
sample streams that are not the first in the queue).
- Checking if none of the previous streams queued any samples in
onStreamChanged to handle this in the same way as the case
where we already output all samples (this fixes the problem when
the empty sample stream comes first in the queue).
- Also calling onProcessedStreamChange for the case above, which
was missing previously.

This change makes sure that the `AdPlaybackState` of any period can
contain an empty postroll placeholder.
The placeholder postroll should be represented in the `MediaPeriodId`
of a content period as `nextAdGroupIndex`, but should be ignored when
building the list of `MediaPeriodInfo` in the `MediaPeriodQueue`. This
is required to allow to add an ad group to ad playback state of the
content period that is currently being played, instantly insert an ad
period into the media period queue and immediately transition playback
to the new period.
This change makes sure and tests that
- a live server side inserted postroll placeholder can be inserted to
a `AdPlaybackState` in well-defined and tested way (helper method)
- a postroll placeholder is NOT ignored when
`AdPlaybackState.getAdGroupIndexAfterPositionUs` is called (this
is required when evaluating the `nextAdGroupIndex`).
- a postroll placeholder is ignored when
`AdPlaybackState.getAdGroupIndexForPositionUs` is called (this is
required to not attempt to play the ad and is analogous to ignore the
post roll placeholder in a single period timeline).
- `MediaPeriod.getFollowingMediaPeriodInfo()` does not include a
`MediaPeriodInfo` for the placeholder postroll when building the
queue.

We currently rely on the raw playback head position to check if any
data is pending in the AudioTrack (e.g. to know if the renderer is
still ready). We can use the value returned from getCurrentPositionUs
instead to align the "isReady" logic with the playback position logic.
This has the side effect that getPlaybackHeadPosition position is called
less often when the position is obtained via getTimestamp.
PiperOrigin-RevId: 514747613
Once the value returned from AudioTimestampPoller advances, we
only need getPlaybackHeadPosition to sample sync params and
verify the returned timestamp. Both of these happen less often
and we can avoid calling getPlaybackHeadPosition if we don't
actually need it.
PiperOrigin-RevId: 512882170
Playback parameter signalling can be quite complex because
(a) the renderer clock often has a delay before it realizes
that it doesn't support a previously set speed and
(b) the speed set on media clock sometimes intentionally
differs from the one surfaced to the user, e.g. during
live speed adjustment or when overriding ad playback
speed to 1.0f.
This change fixes two problems related to this signalling:
1. When resetting the media clock speed at a period transition,
we don't currently tell the renderers that this happened.
2. When a delayed speed change update from the media clock is
pending and the renderer for this media clock is disabled
before the change can be handled, the pending update becomes
stale but it still applied later and overrides any other valid
speed set in the meantime.
Both edge cases are also covered by extended or new player tests.
Issue: google/ExoPlayer#10882
#minor-release
PiperOrigin-RevId: 512658918
MediaCodecRenderer currently has two independent paths to trigger
events at stream changes:
1. Detection of the last output buffer of the old stream to trigger
onProcessedStreamChange and setting the new output stream offset.
2. Detection of the first input buffer of the new stream to trigger
onOutputFormatChanged.
Both events are identical for most media. However, there are two
problematic cases:
A. (1) happens after (2). This may happen if the declared media
duration is shorter than the actual last sample timestamp.
B. (2) is too late and there are output samples between (1) and (2).
This can happen if the new media outputs samples with a timestamp
less than the first input timestamp.
This can be made more robust by:
- Keeping a separate formatQueue for each stream to avoid case A.
- Force outputting the first format after a stream change to
avoid case B.

When rendering frames at a rate higher than the screen refresh rate,
e.g. playing at 8x, the player is releasing multiple frames at the same
release time (nanos) which are then dropped by the platform. The output
buffers are available later and as a result MediaCodec cannot keep up
decoding fast enough.
This change skips releasing multiple video frames on the same vsync
period and proactivelly drops the frame. The frame is counted as skipped
rather than dropped to differentiate with frames dropped due to slow
decoding.

Rename ScaleToFitTransformation to ScaleAndRotateTransformation.
This better represents the operations that can be accomplished using this

to scale to fit using OpenGL, and this effect handled the scaling to fit in a way that no other MatrixTransformations did.
However, it's hard to discover how to rotate when skimming names of effects, so
it's probably more useful to convey that this effect rotates, than that it
scales to fit.

The AsynchronousMediaCodecAdapter's queuing thread stores any exceptions
raised by MediaCodec and re-throws them on the next call to
queueInputBuffer()/queueSecureInputBuffer(). However, if MediaCodec
raises and error while queueing, it goes into a failed state and does
not announce available input buffers. If there is no input available
input buffer, the MediaCodecRenderer will never call
queueInputBuffer()/queueSecureInputBuffer(), hence playback is stalled.
This change surfaces the queueing error through the adapter's dequeueing
methods.

If a renderer error happens while processing readahead data for the
next item in the playlist, we currently throw the error immediately
and only set the item id in the error details. This makes it harder
to associate the error to the right item. For example, the user
facing UI is likely not updated to show the failing item when the
error is reported.
This can be improved slighly by force setting the position to the
failing item. The playback still fails immediately, but this can't
be avoided because the renderer itself went into an error state.

The AudioTrackPositionTracker needs to correct positions by
the speed set on the AudioTrack itself whenever it makes
estimations based on real-time (=the real-time playout
duration is not equal to the media duration played).
This happens for the main playback path already, but not for
the mode in which the position is estimated from the playback
head position and also not in the phase after the track has
been stopped. Both cases are not very noticeable during
normal playback, but become relevant when playing in offload
mode.

This makes it easier to reason about some parts of the code and
will eventually allow to easily switch between AudioProcessor-
based on AudioSink-based speed adjustment.
The current state saves the applicable playback parameters
in separate variables depending on which speed adjustment
path is used. Moreover, the AudioProcessor-based logic keeps
a chain of pending parameter changes and we derive the last
applicable one everytime we need the current parameters.
After this change, this is simplified by
- keeping a common value for playback parameters independent
of the actual path we use for adjustment.
- keeping the final ("current") parameters directly, instead
of deriving it from a chain of yet to be applied parameters.

When audio processors are enabled during tunneling, they must produce
output immediately, ensuring that the timestamps of the output samples
correspond to the input and that no additional samples are produced.
This requirement is documented in the Javadoc of DefaultAudioSink.
However, this alone doesn't guarantee all buffers are immediately
written to the AudioTrack, because the AudioTrack writes are
non-blocking and may need multiple attempts.
When draining the audio sink at the end of the stream, we currently
fail in this situation because we assert that the timestamp must be
set (=the drain operation is a no-op). But this may not be true when
the previous non-blocking write wasn't fully handled. We can fix this
by saving the last timestamp and reusing it during draining.

the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.

- Use a single `VideoSize` instance instead of four primitive fields.
- Clarify that the reported size is the decoded size, that is the encoded video
size.

Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.
Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.
Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

An AndroidTest is needed to test the message sending from ExoPlayerImpl to
a video renderer (MCVR in this case). The test will be added later.

These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)

This inconsistency was exposed by an upcoming change to deprecate
`POSITION_UNSET` in favour of `INDEX_UNSET` because position is an
ambiguous term between 'byte offset' and 'media position', as shown
here.
