Move shared test logic to the test runner.
This does increase indirection, which isn't usually preferable in tests.
However, we will have many different tests that would use logic
like this, so this allows us to reduce repetition.

1. For codecs that change timestamps, we need to use greater
or equal instead of just equal for comparison.
2. We should only make this comparison once a value has been
set.
3. The largest queue timestamp isn't updated before using it
for this detection, meaning that we also mark the
second-to-last sample as the last one.

This should make no functional difference because `SampleExporter` always
checks for H.265 and H.264 first. However, in case we ever change that code,
these are used in priority order so it's better to order them accordingly.

We currently pass in the time at which the stream originally started,
but newly enabled renderers should get the current playback position
instead.

When generating silence for AudioProcessingPipeline, audio never
queued EOS downstream.
Linked to this, when silence followed an item with audio, the silence
was added to SilentAudioGenerator before the mediaItem reconfiguration
occurred. If the silence had effects, the APP would be flushed after
silence queued EOS, resetting APP.isEnded back to false, so AudioGraph
never ended.
Regression tests reproduce failure without fix, but pass with it.

For each event, the timestamp and presentation time is logged. The trace can
then be dumped to a tsv file and easily imported in a spreadsheet.

Instead of `text/x-exoplayer-cues`, we will use `application/x-media3-cues`.
The prefix should be `application` not `text` since the encoded form is arbitrary bytes, not necessarily text. The name should not reference `exoplayer`, since the Media3 Extractors (which are not part of `exoplayer`) produce this format.

signalEndOfInputStream is needed for when streams have different amounts of
frames, so that if the primary stream finishes after a secondary stream, it
can end without waiting indefinitely for the secondary stream's matching
timestamps.
onEnded mirrors this API on the output side, which will be necessary to
know when to call signalEndOfInput on downstream components (ex. on downstream)
VideoFrameProcessors

The VideoFrameProcessingTaskExecutor already handles wrapping
GlUtil.GlException errors into VideoFrameProcessingExceptions.
Therefore, stop wrapping this ourselves, so that errors are
attributed to the correct line number with less indirection.

Alters the OverlayShaderProgram implementation to support rotations, however we need to apply the transformations separately in order for them to work as expected so the matrix is removed from the interface in favour of explicit methods.
Adds a rotation test to ensure this ability doesn't regress

The `MediaNotificationManager` registers an internal controller
to each session. This change marks this controller through its
connection hints and provides an API for apps to hide
implementation details of the marking.

`TtmlDecoder` which used to be `SimpleSubtitleDecoder` will now be called `TtmlParser` and implement SubtitleParser interface. For backwards compatibility, we will have the same functionality provided by `DelegatingSubtitleDecoder` backed-up by a new `TtmlParser` instance.
PiperOrigin-RevId: 549700490
It is not part of the `SubtitleParser` interface's promise to give events for all changes to do with `Cue` objects. So while in the past, we would have `endTimeUs` of one Cue event being the `startTimeUs` of the next one, now we have that encoded in `durationUs` and can skip event with empty `Cues`.

This tracker aims to replicate the behavior of a specific codec to
ensure MediaCodecRenderer correctly detects stream and output
format transitions. The class was needed because MediaCodecRenderer
made assumptions about codec behavior this codec did not fulfil (in
particular, changing timestamps and number of samples).
Since then, MediaCodecRenderer was made more robust to this kind of
codec behavior in general and currently has no assumptions that
require any special handling of this codec. This means we can remove
the workaround completely.

This is no longer flaky because WebVTT subtitles are decoded on the
loading thread (enabled in this test with
`defaultExractorsFactory.setTextTrackTranscodingEnabled(true)` - and
supported for WebVTT since f0f24aa0d4).

The class tries to be flexible to support as many different input
and codec behavior combinations as possible. But so far it didn't
spell out its remaining assumptions and explicit non-assumptions,
making it hard to know which behavior to rely on.

Updated `ExoTrackSelection` to provide the most recent bitrate estimate, enabling the inclusion of measured throughput (mtp) as a CMCD-Request field in Common Media Client Data (CMCD) logging.
Additionally, made changes to the `checkArgument` methods in `CmcdLog` to prevent the use of default values in certain cases.

`WebvttDecoder` which used to be `SimpleSubtitleDecoder` will now be called `WebvttParser` and implement `SubtitleParser` interface.
For backwards compatibility, we will have the same functionality provided by `DelegatingSubtitleDecoder` backed-up by a new `WebvttParser` instance. `WebvttSubtitle` will still be used behind the scenes to handle overlapping `Cues`.

The end-to-end test output for the overlapping SRT and SSA subtitles
is currently incorrect. They will be fixed in a future change that
updates `TextRenderer` to support this overlap.
The 'extra' samples visible in the extractor test output files are
'empty cue list' samples produced by `SsaParser`. They will go away
when this implementation is updated to remove this behaviour and rely
on `CuesWithTiming.durationUs` instead (the 'empty list' behaviour is
not required by the `SubtitleParser` interface).

The main demo app was still targeting API 29 to avoid scoped storage
restrictions. It is now updated to 34 (like the rest of the demo apps)
and handles scoped storage as it should handle it.
More specifically:
- We need to request READ_MEDIA_... permissions instead of
READ_EXTERNAL_STORAGE from API33.
- The legacy scoped storage opt-out can be removed
- READ_MEDIA_... permissions don't allow arbitrary file access
if the file doesn't end in a typical media file extension, so
this change adds a remark on the guide page to place samples
in the app-specific directory.
- We also don't have to request permissions for the app-specific
directories.
- Custom json files can't be placed in arbitray local locations
because they don't end in a media file extension, as there is
no way we can request a permission to load them. This means we
can remove the storage request logic in SampleChooserActivity.

*** Original commit ***
Mark output sample as decode-only based on start time
We currently do the same check on the input timestamps and
expect the output timestamps to match. Some codecs produce
samples with modified timestamps and the logic is a lot safer
when the comparison with the start time is done on the output
side of the codec.

This ensures the DownloadService stays functional on Android 14
where defining this type is required. On Android 14 and above,
the app also needs to define the DATA_SYNC permission, which is
added to the demo app as well. In the future, this service type
will no longer be supported and DownloadService needs to be
rewritten with another background scheduling framework.

AudioMixingUtil#mix handles input & output in float or Int16 PCM. Given
Float and Int16 use different sample ratnes, this util handles
conversion between the two, based on the encoding being mixed to.
Migrate AudioMixer to use the util, removing AudioMixingAlgorithm
interface and implementation. ChannelMixingAudioProcessor will be
migrated after additional performance checks.

This was done because it was deemed correct to only start at timestamp
zero when the code was originally written. However, in case of
prerolling from a keyframe, many samples will get the same timestamp,
which is not correct and interferes with downstream logic
that deals with timestamps.

This fixes two things in one go:
1. In order to indicate 'end of a cue' **without** relying on
`CuesWithTiming.durationUs`, `SubripParser` should have been emitting
an empty `List<Cue>` instead of the current behaviour of a
single-item list with `cue.text=""`.
2. There's no need for the empty cue (or cue list), we can use
`durationUs` to indicate the end of each list of cues.
There's no real need to ever have a `Cue` with `text=""`, so also
deprecate `Cue.EMPTY`.
