This is a new `DataSource` that can be used to read from a `FileDescriptor`.
Limitations:
- The provided file descriptor must be seekable via lseek.
- There's no way to duplicate a file descriptor with an independent position (it
would be necessary instead for the app to provide a new FD). Therefore this
implementation will only work if there's one open data source for a given file
descriptor at a time.

Parse LHEVCDecoderConfigurationRecord with the ‘lhvC’ type and set the corresponding sample mime type to video/mv-hevc. With no MV-HEVC decoder available, fallback to single-layer HEVC decoding.

The default value is 50 seconds.
Changed it to 5 seconds.
This prevents the player from buffering too much data and causing the app to crash due to OOM.

The VideoSink has an input and an output surface. Clarify which surface
the Javadoc is referring to. Also document that the VideoSink can be fed
with images, and that multiple renderers can feed the same sink.

MCVR crashed because MCVR registers a new input stream to VideoSink on every
`onOutputFormatChanged()`, assuming that `onOutputFormatChanged()` is only
invoked on media item transition. However, it can be called multiple times for
one media item.

Hardware decoder on some devices fails to write 1920x1080 YUV_420_888 buffers into an ImageReader. This change allows us to remove skipCalculateSsim device workaround in ExportTest.java.
VideoDecodingWrapper now uses media3.MediaExtractorCompat: necessary for parsing of MediaFormat#KEY_CODECS_STRING and decoder capabilities check

Lint somehow complains that the integer resulting from the bit-manipulation shouldn't be passed as an @IntDef parameter.

Deprecate `setInputDefaultBufferSize` and `setRequireRegisteringAllInputFrames`
as the new input stream type replaces these (as far as we know they are always
used together).
This is in preparation for supporting asset loaders signaling that they require
these features, specifically for recording from a surface.

This is required before we can move CEA-6/708 parsing from the rendering
side of the sample queue to the extraction side.
This re-ordering is needed for video encodings with different decoder
and presentation orders, because the CEA-6/708 data is attached to each
frame and needs to be processed in presentation order instead of decode
order. This change re-orders frames within a group-of-pictures, but also
takes advantage of `maxNumReorderFrames/Pics` values to cap the size of
the re-ordering queue, allowing caption data to be released 'earlier'
than the end of a GoP.
Annex D of the CEA-708 spec (which also applies for CEA-608 embedded in
SEI messages), makes the need to re-order from decode to presentation
order clear.

This change extends the error replication to a given set of
error codes (not only authentication error), but only
replicates an error if the caller of the service `Callback`
is a legacy controller. It also makes error replication
configurable so that apps can opt-out and report errors
manually instead, or define the error codes for which
replication is enabled.
The change also removes the restriction of `sendError` only
being available for Media3 controllers. Instead, sending an
error to a legacy controller updates the platform playback
state in the same way as sending the error to the media
notification controller.

Add the following NAL unit parsing utility functions that will be needed for the MV-HEVC support as proposed in Apple's HEVC stereo video interoperability profile:
- NAL unit header parsing to get the layer information needed for MV-HEVC support.
- VPS parsing, including vps_extension() needed for MV-HEVC support.
- SPS parsing modifications to support MV-HEVC.

Upon track transition of offloaded playback of gapless tracks, the framework will reset the audiotrack frame position. The `AudioTrackPositionTracker`'s `AudioTimestampPoller` must be made to expect the reset and cache accumulated sum of `AudioTimestamp.framePosition`.

The user might expect this button to back out to the configuration activity,
but actually it toggles pause/resume (though `cancel` is the method called).

When handling a playback error that originates from a future item in
the playlist, we added support for jumping to that item first,
ensuring the errors 'happen' for the right 'current item'.
See 79b688ef30.
However, when we add this new position discontinuity to the
playback state, there may already be other position discontinuities
pending from other parts of the code that executed before the
error. As we can't control that in this case (because it's part
of a generic try/catch block), we need to send any pending
updates first before handling the new change.

Setting a `null` value doesn't remove the key as expected per the `MediaFormat` API documentation, using the `removeKey` method instead which is only available starting API level 29.
