This refactors the `supportsFormat` method on the MediaCodecVideoRenderer to be a static method that can be called from external components to determine if a video format is supported by the device renderers. Since `context` is the only component that is part of the MCVR, it can easily be obtained externally and passed to the method.
This can help optimize format support decisions ahead of time of a player having been instantiated, such as removing unsupported representations from a dash manifest.
This could also be done for the MCAR but would also require passing in the AudioSink and isn't required at this time.
This change is a no-op, because
`SubtitleTranscodingExtractorOutput.seekMap` forwards directly to the
delegate implementation, but it seems clearer to always use the
wrapper.
Also remove a no-op assignment in `MatroskaExtractor`.
This is a follow-up to Issue: androidx/media#1779 where I manually checked every
implementation of `Extractor.init` for a similar mistake.

These Uris are not widely supported yet and were only meant to be
used with content Uris. Restricting this more tightly allows
controllers to use these Uris more easily as they have a stricter
guarentee on what it's needed to load these Uris. Media session
apps with different types of Uris can convert them by setting up
a ContentProvider if needed.

PlaybackVideoGraphWrapper will soon contain an input and an output video
sink, as the rendering of the VideoGraph output frames will be handled
by a DefaultVideoSink instance.

This CL also fixes EOS handling to account for not-yet-copied samples in
`remainingInputToCopyFrameCount`, which would throw off the final output
sample count calculation.
For testing, we allow a tolerance of 0.000017% drift between expected
and actual number of output samples. The value was obtained from running
100 iterations of `timeStretching_returnsExpectedNumberOfSamples()` and
calculating the average delta percentage between expected and actual
number of output samples. Roughly, this means a tolerance of 40 samples
on a 90 min mono stream @48KHz.

Just clearing the overrides only helps if a text override was
previously set. If the text is shown because of app defined track
selection parameters for language or role flags, the "none" button is
currently not working and we need to clear these flags explicitly.

IMA always starts midrolls at index 1. So if there is no preroll ad,
the ad group index in AdPlaybackState is off by 1 all the time, and
may also lead to ArrayIndexOutOfBoundsExceptions when trying to access
the last midroll ad

The workaround in ExternalTextureManager.forceSignalEndOfStream
was being applied even when the decoder did output all frames, and only
the GL pipeline was slow.
This change ensures that workaround is not applied when the decoder
has already produced all output frames.

If a codec received the EOS signal and already returned the last
output buffer, we should expect the output EOS very quickly. If
it doesn't arrive within 100ms, we can proceed to end the stream
manually without waiting any further to prevent cases where the
codec is completely stuck otherwise.

Some devices can encode portrait 720x1080 but not landscape
1080x720. But VideoSampleExporter always prefers encoding
landscape. Have `assumeFormatsSupported` mirror sample exporter
logic more closely

The buffered position was last updated before the beginning of
the renderer loop in doSomeWork. As the loading happens on a
background thread, it may have progressed further already
depending on how long it took to run the renderer loop.
It's slightly more correct to pass in an updated value to
shouldStartPlayback so that playback can start quicker if the
buffering is particularly fast.

We began to use a different preload thread than the main thread in the `DefaultPreloadManagerTest`, then in the test execution, we should also ensure that the events queued on the preload looper have been executed.
Also, there is an edge case also causing flakiness. Assume that `DefaultPreloadManager` is preloading source B, then the app invalidates and triggers another sequence of preloading, say they are A, B and C. There is possibility that source B finishes preloading (started before `invalidate`) when A starting to preload, then `onPreloadSkipped` will be triggered for source B instead of `onPreloadCompleted`. However, the functional block inside of `onPreloadSkipped` is dispatched asynchronously, and by then it's possible that B starts to preload again at the consequence of A being completed, then the functional block just mentioned may think that the current source matches at B, and will advance the current preloading source to C, without informing the `Listener.onPreloadCompleted` for it. As the result, the `Listener.onPreloadCompleted` can never be triggered for B for the second sequence. To fix this, we should prevent the functional block in `onPreloadCompleted`, `onPreloadError`, `onPreloadSkipped` to be even dispatched, when the source doesn't match the current preloading one.

The MetadataRenderer by default supports icy and vnd.dvb.ait content. Those tracks should therefore be set with the `C.TrackType` `TRACK_TYPE_METADATA` rather than `TRACK_TYPE_UNKNOWN`.

When a Media3 controller calls play on a Media3 session, the call
is currently not routed through the platform session at all.
This means the usual exemption to start a FGS for media controller
interactions is not triggered.
We can manually ensure this exemption is given by sending a custom
platform command to the session. The Media3 session will never
receive this command as it's not a known Media3 custom command.
Sessions will see a single onConnect call with a platform controller
from the sender app though. We can prevent this on newer versions of
the code by dropping the onCommand call early.

The max number of commands for media items of a browser or controller
can be configured with `setMaxCommandsForMediaItems(int)` on
`MediaController.Builder` and `MediaBrowser.Builder`. An app that has
only limited space for displaying commands can hint this limit to the
session.
A session can receive the value of a connected browser or controller
through `getMaxCommandsForMediaItems()` of a `ControllerInfo` that
is passed into every callback method. The session can then pick the most
sensible commands instead of making the browser app truncating the commands
rather randomly.
When a `MediaBrowser` is connected against a legacy `MediaBrowserServiceCompat`,
the max number of commands is automatically added to the root hints. Conversely,
the value passed in with the root hints to `MediaLibraryService` by a legacy
`MediaBrowserCompat`, is read into `ControllerInfo` like for a Media3 browser.

To avoid rounding errors, set the `Rounding mode` of the `uvFromVu` and `vuFromUs` results to `HALF_UP`. This `Rounding mode` rounds numbers towards the "nearest neighbor" unless both neighbors are equidistant, in which case round up.

- `MediaMetadata.supportedCommands` is converted to an array list of
strings into the extras of `MediaDescriptionCompat` with `DESCRIPTION_EXTRAS_KEY_CUSTOM_BROWSER_ACTION_ID_LIST` and vice versa.
- The set of media item command buttons of a session is passed in the
root hints to a legacy browser that connects. A Media3 browser connected
to a legacy service, gets the set of all commands after calling
`getLibraryRoot()`.

Note that unlike the legacy implementation, custom media items
commands can be used for any media items with Media3 API. This
includes `MediaItem` instances that are received from sources
different to `MediaLibraryService` methods.
Hence when connected against a Media3 session these custom commands
can be used with a `MediaController` as well as with a `MediaBrowser`.
Interoperability with `MediaBrowserServiceCompat` will
be added in a follow up CL.

This check is also done when setting a surface on ExoPlayerImpl,
but by the time we configure the codec the surface may have become
invalid (e.g. when it is destroyed). Even though we immediately remove
a destroyed surface, we could still accidentally use it before the
removal is processed. To avoid these edge cases, we can simply not
configure the codec with an invalid surface.

Access is package-private and it will allow the media controller logic
to interact with the underlying platform session directly if needed.
Interop: When a MediaController connects to an older session (before this
change), it won't get the platform token from the session directly.
Many controllers will be set up with a platform or compat token though
and we can simply keep the already known token and use it. The only
cases where we still don't have a platform token in the MediaController
are the cases where the controller is created with a SessionToken based
on a ComponentName.
