From ANSI-CTA-608-E R-2014 section 8.4:
> When closed captioning is used on line 21, field 2, it shall conform
> to all of the applicable specifications and recommended practices as
> defined for field 1 services with the following differences:
> 1. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x14, 0x20 to 0x14, 0x2F in field 1,
>    shall be replaced with 0x15, 0x20 to 0x15, 0x2F when used in field
>    2.
> 2. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x1C, 0x20 to 0x1C, 0x2F in field
>    1, shall be replaced with 0x1D, 0x20 to 0x1D, 0x2F when used in
>    field 2.

This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.

The `isMiscCode`  method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.

Split inner interface into separate file, which will go in common
module. The old interface will be deprecated and extends the new.

The inner class avoids a verification failure, which can lead to slower
execution at runtime.

This is a no-op, but it's more 'correct' because it avoids any potential
sign mix-ups that come from storing an unsigned byte (with a
potentially set MSB) in a signed java byte variable.

Although it can be useful to check the output format, it's not required or needed.

For some AudioProcessor implementations, it is stated/obvious that
the output format will match the input, in which case there is no
a need to check the return value.

Make it easier to support use of RGBA_101012 rather than RGBA_8888 for EGL
contexts, displays, and surfaces.

This tangentially supports adding HDR tests, by slightly simplifying the color
selection logic we'd have to add in HDR tests.

The reason for making the Muxer public is that we want to add an option
to disable or configure the timer that will throw when the muxer doesn't
receive any data for a given period of time.

The MediaNotficationManager stops the service from the foreground
calling Service.stopForeground(boolean) which is deprecated in API 33.
This change calls Service.stopForeground(int), which was added in API
24.

This was originally added in https://github.com/androidx/media/commit/4fd7d777b669f6adacc3737a7e15b04a57f030fb, but it hasn't done anything
since https://github.com/androidx/media/commit/98ee159df161c7c8806c0b0490b642738822f6a7 (when the instanceof ExoPlayer check was removed).

Before, they used `width` and `height`, which was inconsistent with other pixel tests, and less descriptive.

Refactoring change only. No functional change intended.

PiperOrigin-RevId: 481970243
(cherry picked from commit cce79a70)

Currently, repeating the same item (via seekNext/Previous) implicitly
results in a seek to the default position of the current item, which
looks exactly the same as a direct seek. As a result, we don't send
onMediaItemTransition as we would for every other seekNext/Previous
call.

This can be fixed by explicitly marking the repeat case in the internal
BasePlayer/ExoPlayerImpl methods, so that the callback can be triggered.

PiperOrigin-RevId: 481951788
(cherry picked from commit f850206c)

This is the first commit out of two. This change adds the missing event
flags for the onEvents() callback when MediaController is connected to a
media3 session (see MediaControllerImplBase). I updated the
MediaControllerListenerTest and MediaControllerStateMaskingTest with
assertions that on onEvents() is called alongside individual
Player.Listener callbacks.

There will be a follow-up change for the case where a MediaController is
connected to a legacy MediaSession (MediaControllerImplLegacy). I've
split this in two separate changes to make the size of the commit
manageable for reviewing.

- The naming DefaultMuxer is more consistent with the rest of
Transformer codebase (e.g. DefaultEncoderFactory).
- By hiding the implementation details of DefaultMuxer, the transition
to in-app Muxer will be seamless for apps using DefaultMuxer.
- The current plan is that DefaultMuxer will become the in-app muxer.
