This property is transformer specific and does not belong to
muxer interface.
This is to eventually replace muxer interface in Transformer module with
muxer interface in Muxer module.

This ensures MediaMetadata with just non-null extras is not
considered equal to MediaMetadata.EMPTY. This makes sure the
contents are bundled when a controller sets the extras in a
new MediaItem

The immediate plan is to replace `Transformer Muxer interface`
with this one.
It was not straight forward to move/change `Transformer Muxer interface`
hence this intermediate step.
The follow up CL will also remove fragmented MP4 related code from
`Mp4Muxer` and move it into `FragmentedMp4Muxer implements Muxer`.

This is the most widely-used test-skipping method I'm aware of, so I figured this
would be a great method to scale usage of AssumptionViolatedException.

Ideally the test to transmux a `ts` file (having 3 bytes NAL start code)
should go into `Mp4MuxerEndToEndTest`but `Mp4MuxerEndToEndTest` uses `MediaExtractor` and `MediaExtractor` is returning samples with `4 byte NAL start code` which will not exercise the newly added code path.
Hence the test is added in `TransformerWithInAppMuxerEndToEndTest` which
internally uses `media3 extractor` and feeds samples with `3 bytes NAL start code`
only.

Seeking will consist of the following steps:
- Block the AudioGraph input data.
- Flush the AudioGraph.
- Seek the ExoPlayers.
- Unblock the AudioGraph input data.

The original change did not set the color info in the codec
for standard SDR infos. This was meant to help with consistency
to avoid a situation where the information is partially set and
later the bitstream provides slightly different values (all in
standard SDR though).
We can revert this part because the bitstream may change anyway
and the decoder needs to handle this internally. And more
importantly, it also avoids removing this information when encoding
the format again in Transformer.

This refactoring is required to support 3 byte NAL start code, in which
the sample ByteBuffer might change after AnnexB to Avcc conversion.
This would required changes in the corresponding BufferInfo as well.

Some media can read color info values from the bitstream
and may partially set some of the SDR default values in
Format.ColorInfo. Setting these default values for SDR can
confuse some codecs and may also prevent adaptive ABR
switches if not all ColorInfo values are set in exactly the
same way.
We can avoid any influence of HDR color info handling by
disabling setting the color info MediaFormat keys for SDR
video and also avoid codec reset at format changes if both
formats are SDR with slightly different ColorInfo settings.
To identify "SDR" ColorInfo instances, we need to do some
fuzzy matching as many of the default values are assumed to
match the SDR profile even if not set.

The AV1 video stream does not contain NAL unit which is a concept
specific to H.264/H.265.
This was not caught before muxer does an in place replacement of
`NAL start code` with `NAL length`. In the absence of `NAL start code`
it was automatically a no-op.

nullness checks were removed a while ago from editing, so no need for them now.
Bit neater to have less code to parse too.
Also, removes RequiresNonNull
PiperOrigin-RevId: 616887502
This also makes it more consistent with newer testId tests that don't have nullness, so tests don't look inconsistent, and was pretty easy to do :P

This was broken by 2fa38d15dd, which added an assumes
method, but missed the `!` operator for the tests where HDR is
unsupported. Add an assumes method that assumes a lack of support
for HDR.
Tested on the failing device (Pixel 7) and confirmed this fixes
the test on that device, to throw AssumptionViolatedException
instead of allowing test logic to run after failing the
assumption.

Add a new method `onUsedByPlayer(PreloadMediaSource)` for `PreloadMediaSource.PreloadControl`, which will be invoked when the player starts to use the `PreloadMediaSource`, or calling `PreloadMediaSource.preload` while the player is already using that source. `DefaultPreloadManager` will immediately preload the next source when receiving `onUsedByPlayer` event.

Confirmed that the HLG extension displays properly on Pixel 7 Pro, API 34 and Samsung S24, API 34. On these devices, this fixes the washed out HLG preview issue on API 34, where the PQ ext had a washed out look, and where the HLG ext is supported (this bug didn't occur on API 33, only 34).
More info on manual tests done to sanity-check:
* Test cases: Transformer debug SurfaceView and ExoPlayer.setVideoEffects
* Test inputs: HLG and PQ
* Test devices: Pixel 7 Pro (API 33 & 34), Samsung Galaxy S24 (API 34)
* Added debugging: Logging colorInfo used in GlUtil.createEglSurface
No regressions were seen. HLG extension is used more in API 34, and behavior stays the same on API 33. Only human-visible change without logging is that HLG content looks better on API 34, for Samsung S24 and Pixel 7 Pro.

It's a bit arguable whether the `Subtitle` implementation supports
zero-duration events, since `getEventTimeCount` is documented as
effectively "the number of times the cues returns by `getCues(long)`
changes", and zero-duration events violate that. However, the current
`WebvttSubtitle` impl **does** produce zero-duration events, so it
seems safer to handle them gracefully here and then, as a possible
follow-up, fix the `WebvttSubtitle` impl (or remove it completely).

When flushing the AudioGraph, the AudioMixer will be preserved but the
sources will be recreated. This is probably a bit less efficient but
makes the logic simpler. Indeed, if we had to keep the sources alive,
we would need to add a way to reconfigure them with a new timestamp for
seeking. We would also need to change the way sources are ended because
they are currently removed when they are ended. Also, it is acceptable
to have a small delay when seeking, which means that performance is less
critical than for playback.
