The latest version of `androidx.compose.foundation:foundation` fixed an issue where `AndroidEmbeddedExternalSurface` would not reset properly. This in turn prevented PlayerSurface Composable with type `SURFACE_TYPE_TEXTURE_VIEW` from being redrawn after returning to a stopped activity.

Added reporting 2 values from Transformer:
- elapsed time since creation of the `editingSession` in milliseconds.
- the `ErrorCode` for export errors. The error codes were mapped from `@ExportException.ErrorCode` int to `@EditingEndedEvent.ErrorCode`.

For the [0.5; 1) speed range, the combination of having a "slow down"
speed (i.e. more output frames than input frames), and Sonic potentially
needing to copy more input frames that are available in the input buffer
can lead to an unexpected underflow.
Specifically, the underflow happens in Sonic#queueEndOfStream() when the
following conditions are met (skipping some minor ones):
1. `inputFrameCount < remainingInputToCopyFrameCount`
2. `0.5f <= speed < 1`.
3. `outputFrameCount <
(inputFrameCount / remainingInputToCopyFrameCount) / 2`.
This underflow caused `SonicAudioProcessor#isEnded()` to return a false
negative (because `getOutputSize() != 0`), which would stall the
`DefaultAudioSink` waiting for processing to end after EOS.
In practical terms, the underflow is relatively easy to reproduce if we
consume all of Sonic's output and then immediately queue EOS without
queueing any more input in between. This should cause both
`inputFrameCount` and `outputFrameCount` to drop to 0.

Added a new `EditingMediaMetrics` class that interacts with the platform's `MediaMetricsManager` through an `EditingSession` created when export starts.
Currently, only the `finalState` of the export event is reported to the `EditingSession`. Future changes will collect additional metrics based on the export operation's output.

Some videos include zero length NAL units in the
length-delimited MP4 samples.
Empty NAL units are not spec-compliant (see ISO/IEC 14496-15 section 4.3.3.3),
but other players are able to play these videos (with warnings or errors).
With this change, we check track.sampleTable.sizes[sampleIndex] before
reading a byte from the NAL unit itself.

The static method can estimate the number of input frames needed to get
a given number of output frames with a given Sonic configuration.
This CL is prework to remove the dependency of
`SpeedChangingAudioProcessor#getMediaDurationUs()` on non-static output
based heuristics and simplify `SpeedChangingAudioProcessor`.

On many devices (for example pixel 7) a dolby vision file can be
decoded (either using dolby vision decoder or H265 decoder)
but they can't be re-encoded to dolby vision.
Allow test to encode to H265.
The test now passes on pixel 7. It was getting skipped earlier.

A device (for example pixel 7) might support HDR encoding
but with H265 sample mime type but the existing condition made
assumption false on such devices.
The test still does not pass on pixel 7 because the format
matching condition is incorrect. It will be fixed in a separate CL.

Replaced an existing APV file as bitstream syntax has now changed and
previous clip is not a valid bitstream anymore.
This clip was provided by the openAPV team and is under BSD-3 license.

After this change if a sample rate is requested that is not supported by the available encoders and enableFallback is true, DefaultEncoderFactory will fall back to the encoder with the closest matching sample rate.
In the case when an encoding profile is included in requestedAudioEncoderSettings, an encoder matching that profile will continue to be preferenced.

Added a new `usePlatformDiagnostics` in Transformer. This parameter enables/disables forwarding editing events and performance data to the platform.
This is pre-work for metrics support in Transformer. In the following CLs, metrics collection and forwarding will be implemented.

- Added a condition to ensure `requiredIntervalUs > 0` in `DashMediaSource`.
- Resolves an issue where negative `requiredIntervalUs` triggered an infinite loop in `onPlaylistUpdateRequested()`, leading to application/stream freezes.
This fix restores smooth playback for multi-period DASH streams.
AMR-NB and AMR-WB are inherently mono, so channel count is set to 1. Sample rate is also hard-coded to adhere to codec standards.
Also removed unused parameter `hasAdditionalViews` in `StriData`.

The dump file for VP9 mp4 clips varied across SDK versions due to inconsistent CSDs from the platform extractor. By replacing the platform extractor with `MediaExtractorCompat`, the Media3 extractor will provide consistent CSDs across all SDK versions.

This enables `AdsMediaSource` to be used with a live media
source that has a growing `AdPlaybackState` to which ad groups
can be appended.
Before this change, `AdsMediaSource` asserted that the number
of ad groups was kept the same, else an exception was thrown.
After this change, the assertion checks the validity of the
update and throws in case the update isn't considered valid.
An update is valid if ad groups are appended to the existing
`AdPlaybackState` or ads are appended to existing ad groups.
Further the `adGroupIndex` and `timeUs`of an existing ad
group can not be changed and once a media item is set for a
given ad, that media item can't be changed either.
