Previously any `CuesWithTiming.durationUs` could be `TIME_UNSET`,
meaning it should be replaced by the next `CuesWithTiming` instance
(instead of being merged if the durations overlap, which is currently
the expected behavior for all `CuesWithTiming` with a 'real' duration).
This technically allowed a single subtitle track to include a mixture of
`CuesWithTiming` that should be merged, and some that should be
replaced. This is not actually needed for any of the subtitle formats
currently supported by ExoPlayer - in all cases a format expects either
all cues to be merged, or each cue to replace the previous one.
Supporting this mixture of merging and replacing in `TextRenderer` ended
up being very complicated, and it seemed a bit pointless since it's not
actually needed. This change means a given subtitle track either merges
**all** cues (meaning `CuesWithTiming.durationUs = C.TIME_UNSET` is not
allowed), or **every** cue is replaced by the next one (meaning
`CuesWithTiming.durationUs` may be set (to allow for cues to 'time out',
needed for CEA-608), or may be `TIME_UNSET`).
This value will be used in a subsequent change that adds cue-merging
support to `TextRenderer`.

This is equivalent to the existing `scaleLargeTimestamp` method with the
following changes/improvements:
* No longer specific to timestamps (there was nothing inherently
time-specific about the logic in `scaleLargeTimestamp`, but the name
and docs suggested it shouldn't be used for non-timestamp use-cases).
* Additional 'perfect division' checks between `value` and `divisor`.
* The caller can now provide a `RoundingMode`.
* Robust against `multiplier == 0`.
* Some extra branches before falling through to (potentially lossy)
floating-point math, including trying to simplify the fraction with
greatest common divisor to reduce the chance of overflowing `long`.
This was discussed during review of 6e91f0d4c5
This change also includes some golden test file updates - these
represent a bug fix where floating-point maths had previously resulted
in a timestamp being incorrectly rounded down to the previous
microsecond. These changes are due to the 'some more branches' mentioned
above.

While debugging various session tests failure I found that sometimes
this list was empty (e.g. when a controller had failed to connect, or
hadn't finished connecting yet) - resulting in these methods being
silent no-ops. I think it's basically never expected for there to be no
controllers connected when these methods are invoked, so this logs at
ERROR level to give a clue of what happened when looking at the test
logcat.

For pause and resume feature we need to use same `MuxerWrapper`
for `remuxing processed video` and then to `process remaining video`.
In order to use same `MuxerWrapper` across `different Exports`
we need to preserve its state.

This aligns the equivalent implementation in `MockMediaSessionService`,
and it looks more correct to me - but the tests seem to pass both with
and without this change (and it doesn't seem to affect flakiness
either).

It's much better to merge the windows at source level to reflect the
same state everywhere (e.g. notifications, player state, etc). This
can be done with ConcatenatingMediaSource2.
PiperOrigin-RevId: 563715718
There is no known use case left that needs to be solved by this
class. All other use cases are better solved by alternative
approaches (Player playlist methods or ConcatenatingMediaSource2).

The class currently disallows offsets of periods in their windows
except for the very first window. This is not necessary because
we can use TimeOffsetMediaPeriod to eliminate the offset if needed.
This makes the class more useful for many use cases, in particular
for using it with ClippingMediaSource.

Modifying dumping to not required "released" to be called.
Track index is an arbitrary value based on the order of addTrack calls.
Samples are dumped by track (rather than as soon as they are written),
so it's preferable to use a value that provides more context.
By using the track type as a key, dump files will be more deterministic
and will have more similarities when branched.

This callback asks to correct the media time in a composition, but doesn't
provide the MediaPeriodId as the necessary context to do this.

That said, only SDR is supported for now, so this will always throw if
HDR is input. This will also throw if different ColorInfo values are input
because color SDR mixing (ex. between sRGB and BT709) is not yet supported.

While investigating a different test failure on a pending change I
noticed that sometimes the "testAddSessions_removedWhenClose" session
was being released before it could be fully connected - and this
results in a failure like:
```
expected not to contain: androidx.media3.session.MediaSession@50a9ef1
but was : [androidx.media3.session.MediaSession@50a9ef1, androidx.media3.session.MediaSession@3a6bac]
at androidx.media3.session.MediaSessionServiceTest.addSessions_removedWhenReleased(MediaSessionServiceTest.java:376)
```
It also shows up in the logs like:
```
MediaController future failed (so we couldn't release it)
...
Caused by: java.lang.SecurityException: Session rejected the connection request.
```
Adding some debug logging revealed that the `session.release` call
posted to the test thread was happening before the call to
`MediaSessionStub.connect` on the main thread (this is triggered deep
in prod media3 session logic).

Instead of invoking "undefined behavior" may occur when a class is used
incorrectly, which is clear but not very helpful to callers, specify what Apps
or users of a class should do when issues occur.
Apply this to Compositor as well, where this otherwise might seem unclear.

For pause and resume feature we will need to build `ExportResult`
from multiple internal Exports. Keeping the `ExportResultBuider` in
`Transformer` class will allow using same builder across different
internal exports.

This change ensures that a different package is used for
`test_session_current/src/main:support_app` and
`test_session_current/src/androidTest:test_app` - previously they used
the same package which was unusual (and possibly led to some confusing
behaviour).

This change avoids using a framework API that is deprecated since
API 31 and works around difficulties with this deprecated API on
devices from some manufacturers on API 33/34.
Manually tested with BT headphone connected to:
- Samsung SM-G920F (API 24)
- Pixel (API 28)
- Samsung SM-A515W (API 33)
- Pixel 6 Pro (API 33)
(verified manually with devices and adb output of dumpsys)

When checking the color transfer, there is no reason that the file should have
exactly two tracks, and this assertion means that this method can't be used
as-is for checking video-only files, for example.

We have an existing logic for recovering the `AudioTrack` from the [ERROR_DEAD_OBJECT](https://developer.android.com/reference/android/media/AudioTrack#ERROR_DEAD_OBJECT)
throws. However, this only applies to the situation when the
`writtenEncodedFrames > 0`.
However, we have a case when `ERROR_DEAD_OBJECT` throws while writing
PCM data. When the `tunneling` is turned on, the `AudioTrack` is set the
flag `AUDIO_OUTPUT_FLAG_HW_AV_SYNC`, and further because of this flag,
it is forced the flag `AUDIO_OUTPUT_FLAG_DIRECT`. When the platform
invalidates the `AudioTrack`, the `AudioTrack` won't be restored by the
platform due to `AUDIO_OUTPUT_FLAG_DIRECT` flag, and `ERROR_DEAD_OBJECT`
is thrown.

This is so CompositionPlayer can customize the Renderers and figure
out when a transition to a MediaItem is made hence it can configure the
effects pipeline with the effects that are specific to the MediaItem.

Created new method `AudioSink#setOffloadDelayPadding` that will set delay and padding data onto an `AudioTrack` using `AudioTrack#setOffloadDelayPadding`. This feature adds support for offloaded, gapless Opus playback as the content requires the capability to set padding data post-`AudioSink#configure`.

Overlays may be overlaid over:
* In VideoFrameProcessor, videos or images (or texture input).
* In Compositor, other videos.
In Compositor, Overlays may consist of video, so it could be confusing
for videoFrameAnchor to contrast with overlayAnchor.
Also, rename overlayAnchor to overlayFrameAnchor, since it's modifying
the anchor in the overlay's frame, so this name seems slightly more precise.

This change makes capturing components in CapturingRenderersFactory
to dump data only they have previously captured any. This is so we can
extend the CapturingRenderersFactory with more renderers that do not
capture data in pre-existing tests and we don't have to change the
golden files.
