The current metadata updates are triggered by item transitions,
but depending on the speed of loading the playlist, the first
metadata may only be known later via metadata-change callbacks.
Slow playlist loading also means the UI stays empty and it's
beneficial to show a placeholder to avoid the impressions the
UI hangs.
Finally, clean-up by removing unused string constants and merging
all listeners into onEvents

After 4fad529433, MediaCodecVideoRenderer does not report if frames
are dropped from the VideoSink. This commit fixes this.

This is more correct, though in reality all text-based subtitles handled
by `SubtitleExtractor` are implemented with MERGE behavior in media3.

In some streaming scenarios, like offload, the sink may finish writing buffers a bit before playback reaches the end of the track. In this case a player may pause while in this 'stopping' state.
The AudioTrackPositionTracker needs to update the cached values it uses to calculate position in the `PLAYSTATE_STOPPED`/`PLAYSTATE_STOPPING` states if pause/play are called during this period.
PiperOrigin-RevId: 571345914
In offload mode, `AudioTrack#stop()` will put the track in `PLAYSTATE_STOPPING` rather than `PLAYSTATE_STOPPED`. The difference in state means that `AudioTrack` can be paused and played during this 'stopping' period.
Currently, if `AudioTrackPositionTracker#handleEndOfStream()` has been called then `DefaultAudioSink` in `pause()` won't call `AudioTrack#pause()`. `AudioTrack#pause()` should be called in this case if in offload mode.

This belongs in the resolver, because it depends on the resolution
algorithm (and therefore the logic can't live in `TextRenderer`).
This also fixes a bug in `TextRenderer` where we were doing arithmetic
with `cues.durationUs` without checking if it was `TIME_UNSET` first.

The flag is no longer used by our components and only set and checked
in a few places to guarantee compatiblity with existing renderers and
decoders that still use it.
The flag will be removed in the future due to its design limitations.

The existing `Subtitle` handling code is left intact to support the
legacy post-`SampleQueue` decoding path for now.
This also includes full support for merging overlapping `CuesWithTiming`
instances, which explains the test dump file changes, and which should
resolve the following issues (if used with the
decoder-before-`SampleQueue` subtitle logic added in
5d453fcf37):
* Issue: google/ExoPlayer#10295
* Issue: google/ExoPlayer#4794
It should also help resolve Issue: androidx/media#288, but that will also require
some changes in the DASH module to enable pre-`SampleQueue` subtitle
parsing (which should happen soon).

The aim of this test is to make sure the image is onscreen for the right amount of time, so to drive down flakes from the decoder taking too long, change this to an atLeast check

location and index are mostly equivalent, except that it's possible that location is more up-to-date than index, so we can just always use location.

Set KeepAliveMonitor to send a keep-alive message at half the timeout value, if provided, by the RTSP Setup response.

In most cases this is more useful than `durationUs`.
We will keep `durationUs`, and the constructor will continue to take
`startTimeUs` and `durationUs`, to allow for use-cases where we don't
know the start time but still want to indicate a duration (this will be
used to implement CEA-608 timeout).

Much simpler than ExternalTextureManager flushing, because
ExternalTextureManager complexity is due to decoder race condition behavior,
which we won't see for Bitmaps due to a more well-defined interface.
This is needed to test texture output flushing.

This gets rid of the reliance on the decode only flag that is still
set on input buffers to the decoder if they are less than the start
time.
We still need to set and check the decode-only flag in SimpleDecoder
to ensure compatbility with custom decoders that use the flag while
it's not fully removed.
PiperOrigin-RevId: 570736692
The interface requires the implementation to return null if the
decode-only flag is set. So instead of setting the flag and returning
null, we can simply not call the method and assume it's null.
The only reason where this wouldn't work is if the metadata format
has keyframe-like logic and requires previous metadata to decode
the next one. This is not something we came across before and it seems
ignorable. If that feature is needed in the future, we should instead
add a method to MetadataDecoder to set the first output timestamp.

While sleeping for offload, position is estimated based on time playing. If asleep and AudioTrack is reused, then the position will keep incrementing as the subsequent item plays. That is until wakeup when playing position is updated to the timestamp of the second item. Offload scheduling should be disabled until track transitions fully.

The test is hidden behind the Ignore annotation due to some flakiness just like `webvttInMp4`. However, it will be removed when the subtitle parsing is moved to a pre-sample-queue architecture.

In some cases, SimpleDecoder output needs to be skipped for rendering
because the decoder produces no data. This is one of the remaining
usages of BUFFER_FLAG_DECODE_ONLY at the moment and can be more
directly solved without using the flag. SimpleDecoder still needs to
check the flag though for backwards compatbility with custom decoders
while the flag is not completely removed.
