This method is useful for cases where the target condition can
become true outside of a message on the main thread. To ensure we
don't execute the rest of the test method in parallel with other
code, we have to introduce artifical messages on the main thread
that check the target condition.

For LL-HLS, the non-primary playlists originally keep reloading even after the primary playlist has been changed to another one. The reason being this is to check if the hinted(#EXT-X-PRELOAD-HINT) resource has been published or removed. If removed, the loading of it should be canceled, per the suggestion in the HLS spec:
"A Client SHOULD cancel a request for a hinted resource if it is not present in a subsequent Playlist update, such as in an EXT-X-PRELOAD-HINT tag or as part of another tag such as EXT-X-PART. The client SHOULD ignore the results of such requests."
However, keeping the non-primary playlists reloading is not optimal. As a solution, we trigger the playlist reloading only when there is a preload chunk loading instead of every time after we have processed the playlist. Compared to the original implementation, this will save the requests of reloading non-primary playlist after we have taken action upon the preload chunk being published or removed.

This is the preparation to import the media1 classes as

- Reword Javadoc to use @code instead of @link to media1 types. This
avoids accidentally linking to the future internal types.
- Use fully qualified names for the converter methods to and from
MediaSessionCompat.Token to ensure they keep the publicly available

- Add new public variable that is directly referenced from our code
instead of referring the the media1 equivalent.
- Clean up tests that are using media1 types to make assertions on
media3 fields and vice versa (mostly when using LegacyConversions
in the test method). This also makes the tests more DAMP than DRY.

Some seek operations are currently filtered in the base classes if
the target index is not explicitly specified and the implicitly
assumed operation doesn't have an obvious target index. (Example:
calling seekToNext() at the last item in a playlist)
This is too opinionated because the actual player implementation
using this base class may be able to handle this seek request (e.g.
by adding new items on the fly or using other logic to select
the most suitable next item).
This can be solved by forwarding all seek requests to the respective
handler methods even if they are a presumed no-op. Also clarify the
Javadoc that the provided index is just an assumption if it wasn't
provided explicitly in the method call.

The join mode is used for two cases: surface switching and mid-playback
enabling of video.
In both cases, we want to pretend to be ready despite not having rendered
a new "first frame". So far, we also avoided force-rendering the first
frame immediately because it causes a stuttering effect for the
mid-playback enable case. The surface switch case doesn't have this
stuttering issue as the same codec is used without interruption. Not
force-rendering the frame immediately causes the first-frame rendered
callback to arrive too early though, which may lead to cases where
apps hide shutter views too quickly.
This problem can be solved by only avoiding the force-render for the
mid-playback enabling case, but not for the surface switching case.

Ideally the test to transmux a `ts` file (having 3 bytes NAL start code)

only.

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.

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.

* Test inputs: HLG and PQ

It's a bit arguable whether the `Subtitle` implementation supports

When flushing the AudioGraph, the AudioMixer will be preserved but the

they are currently removed when they are ended. Also, it is acceptable

Renderers may be enabled for subsequent media items as soon as the current media item's renderer's isEnded() returns true. When a renderer is being enabled and the player is 'playing', that renderer is also started. When playing a mixed playlist of images and content with audio & video, the player may skip some image items because the early-starting of the audio renderer causes a clock update.
A solution is to only start the "early-enabled" renderers at the point of media transition and add a condition on DefaultMediaClock to use the standalone clock when reading-ahead and the renderer clock source is not in a started state.

`BasePreloadManager` coordinates the preloading for multiple sources based on the priorities defined by their `rankingData`. Customization is possible by extending this class.

This change aims to prioritise tracks that have a 'smooth enough for
video' frame rate, without always selecting the track with the highest
frame rate.
In particular MP4 files extracted from motion photos sometimes have two
HEVC tracks, with the higher-res one having a very low frame rate (not
intended for use in video playback). Before this change
`DefaultTrackSelector` would pick the low-fps, high-res track.
This change adds a somewhat arbitrary 10fps threshold for "smooth video
playback", meaning any tracks above this threshold are selected in
preference to tracks below it. Within the tracks above the threshold
other attributes are used to select the preferred track. We deliberately
don't pick the highest-fps track (over pixel count and bitrate), because
most users would prefer to see a 30fps 4k track over a 60fps 720p track.
This change also includes a test MP4 file, extracted from the existing
`jpeg/pixel-motion-photo-2-hevc-tracks.jpg` file by logging
`mp4StartPosition` in
[`MotionPhotoDescription.getMotionPhotoMetadata`](b930b40a16/libraries/extractor/src/main/java/androidx/media3/extractor/jpeg/MotionPhotoDescription.java (L123))
and then using `dd`:
```
mp4StartPosition=2603594
$ dd if=jpeg/pixel-motion-photo-2-hevc-tracks.jpg \
of=mp4/pixel-motion-photo-2-hevc-tracks.mp4 \
bs=1 \
skip=2603594
```

This solution is in addition to the `JpegMotionPhotoExtractor` change
made specifically for these two-track motion photos in
5266c71b3a.
We will keep both changes, even though that change is not strictly
needed after this one, because adding the role flags helps to
communicate more clearly the intended usage of these tracks. This
change to consider FPS seems like a generally useful improvement to
`DefaultTrackSelector`, since it seems unlikely we would prefer a 5fps
video track over a 30fps one.

This new test is for `ExoPlayer.setVideoEffects()`. It plays the
one-second-long video, applies an overlay that prints the video frame timestamp
onto the frame, captures the output frame and compares the captured output
frame with golden.
