Util.getAudioTrackChannelConfig() maps a channel count to a
channel mask that is passed to AudioTrack. The method expected that
playback of 8-channel audio is possible from Android 5.1 and playback of
12-channel audio is only possible from Android 12L. However, there is no
restriction on the upper number of channels that can be passed to the
AudioTrack. google/ExoPlayer#10701 is an example where the audio decoder
outputs 12 channels on an Android 10.

This change removes the restrictions for 8 and 12 channels. Note, we still
do not support playback of arbitrary number of channels as it would require
further changes to DefaultAudioSink.

When we currently trigger the iteration finished event during the
release, we don't mark the event as triggered. This means that
someone can trigger another release from within the callback,
which then tries to resend the event.

We currently skip this calculation entirely, but it can be added by
calculating the window duration using the wrapped window's duration
and the provided AdPlaybackState.

It's not clear to me why presubmit didn't catch this, I briefly
investigated but couldn't work it out - so I'm just going to fix
it and move on.

These aren't caught by presubmit because the classes are annotated
`@VisibleForTesting` and are therefore stripped out by Metalava. However
Metalava doesn't run when we're generating javadoc for real.

(cherry picked from commit 14e23d34)

This involves reducing the visibility of methods/constructors that
are already unusable outside the `androidx.media3.test.utils` package.

#minor-release

PiperOrigin-RevId: 487473005
(cherry picked from commit ca8de0e4)

This uses `@hide` on `protected final` methods to hide them from Dackka
javadoc generation, since these methods are inaccessible to developers
anyway. These symbols will still (currently) be included in artefacts
distributed on Maven (because we don't run Metalava as part of
generating these artefacts).

In some cases I had to change the visibility/finality of methods to make
them `protected final` before adding the `@hide` annotation (but
the impact should be very low, since most of these methods were either
already unusable by app developers, or they shouldn't have been used).

(cherry picked from commit 1cd488ac)

This makes two fixes:
1. Remove `HlsSampleStreamWrapper.Callback` (package-private) from the
   list of interfaces implemented by `HlsMediaPeriod` (`public`) and
   move the implementation to a private inner class instead. This avoids
   Metalava complaining about a public class that inherits from a
   package-private type.
2. Reduce the visibility of
   `RtpPayloadFormat.isFormatSupported(MediaDescription)` from `public`
   to package-private. The `MediaDescription` type is already
   package-private, so this method was already unusable outside the
   package.

#minor-release

PiperOrigin-RevId: 487472781
(cherry picked from commit 9041d7b9)

This makes two types of fix:
1. Align parameter names on overridden methods where the superclass
   has `@param` javadoc.
2. Use `@hide` on `protected final` methods that refer to package-private
   types. This will hide these symbols from Dackka javadoc generation
   but not (currently) from the artefacts distributed on Maven. These
   methods are currently unusable outside their package anyway (e.g. by
   external developers) because of the dependency on a package-private
   type.

This also changes some HLS, SmoothStreaming, and IMA code where I've renamed
parameters of overridden methods to be consistent across the type
hierarchy.

Also, document that we tone map when no HDR features are explicitly set

PiperOrigin-RevId: 487310971
(cherry picked from commit 8bdd2784)

Not setting the color info results in a missing "colr" box in the produced
container, under file/moov/trak/mdia/minf/stbl/stsd/hvc1. This means extractors
will not be able to find out the transcoded file is HDR.

In `Transformer`, this means it can't transcode this transcoded file, because
it currently relies on the container bearing HDR info to construct the
transcoding sample pipeline.

This ensure that ffmpeg error code are properly translated to values that the ExoPlayer decoder understand.
The main gain is that it allows the decoder to properly ignore more cases of invalid data and recover.
The second gain is that the other errors are now proper ExoPlayer errors and no more obscure buffer ones.

This logic is currently in the player renderers. With multi-asset, the
renderers will go into the AssetLoader, which shouldn't be responsible
for muxing.

PiperOrigin-RevId: 486860502
(cherry picked from commit d8754b66)

Problem: We are initialising muxer as soon as we start the transformation. Now the startTransformation() method can be called from main thread, but muxer creation is an I/O operation and should be not be done on main thread.

Solution: Added lazy initialisation of muxer object. The actual transformation happens on background thread so the muxer will be initialised lazily from background thread only.

Another way was to provide an initialize() method on MuxerWrapper which will explicitly initialise muxer object but with this approach the caller need to call the initialise method before calling anything else. With current implementation the renderers are calling MuxerWrapper methods on various callbacks (Not sequentially) and also we are sharing same muxer with multiple renderers so It might become confusing for the caller on when to call the initialise() method. Also there are few methods on MuxerWrapper which dont really need muxer object. So in short it might make MuxerWrapper APIs more confusing.

Validation: Verified the transformation from demo app.

https://github.com/google/ExoPlayer/commit/dda17db261758f7211ffa793ee9cc6fea842addb creation of audio/package-info.java introduced a copybara conflict with the exoplayer2/audio/package-info.java move transformation in copy.bara.sky. Solution was to remove original package-info-common-audio.java and the move transformation as https://github.com/google/ExoPlayer/commit/dda17db261758f7211ffa793ee9cc6fea842addb now covers it.

If an app sets a compileSdkVersion that is lower than the one used to
create AARs of its dependencies, the build process may produce invalid
outputs, for example by stripping methods from the APK that are only
called when the app is running on a new API version.

To avoid this issue, we can enforce that the compileSdk of apps or
libraries depending on ExoPlayer/Media3 is at least the same as the
one we used for compilation when creating the AAR.
