Upon the call of `PreloadMediaSource.preload`, the source will periodically check the source refresh or period loading error, and trigger `PreloadMediaSource.PreloadControl.onPreloadError`. For now, the `DefaultPreloadManager` will skip the problematic source and continue to preload the next source. The checking of the error will be terminated when the source stops preloading or releases.

This utility helps apps to forward to another Player while overriding
selected behavior or state values. The advantage to a ForwardingPlayer
is that the SimpleBasePlayer base class keeps ensuring correctness,
listener handling etc.
The default forwarding logic tries to stay as close as possible to the
original method calls, even if not strictly required by the Player
interface (e.g. calling single item addMediaItem instead of
addMediaItems if only one item is added).

Since the muxer supported only AAC audio codec, the esdsBox was unconditionally created within the audioSampleEntry. This CL refactors the box creation logic by moving it to the codecSpecificBox method. This is to make adding support for new audio codecs easier.

The Timeline, Tracks and MediaMetadata are currently provided
with a list of MediaItemData objects, that are a declarative
version of these classes. This works well for cases where
SimpleBasePlayer is used for external systems or custom players
that don't have a Timeline object available already. However,
this makes it really hard to provide the data if the app already
has a Timeline, currently requiring to convert it back and forth
to a list of MediaItemData.
This change adds an override for `State.Builder.setPlaylist`
that allows to set these 3 objects directly without going
through MediaItemData. The conversion only happens when needed
(e.g. when modifying the playlist).

The value is basically a duplicate of the information stored
in the timeline field. Reducing the source of truth to the
single Timeline also allows acceptance of other Timelines in the
future that don't necessarily have the helper structure of
the playlist.
To allow apps to retrieve the current playlist as it is, we
add a getter instead.

Changes to Mp4Extractor to parse additional sample dependency information
and mark output samples as "no other sample depend on this".
Only applies to H.264 tracks.

The percentage should be interpreted as relative to the size of a parent
node.
This change makes this inheritance work correctly for percentages in
both the parent and child. It does not fix the case of a non-percentage
parent size with a percentage child size.

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.

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.
