This change includes a change in the `IMediaController.aidl` file and needs
to provide backwards compatibility for when a client connects that is of an older or
newer version of the current service implementation.
This CL proposes to create a new AIDL method `onPlayerInfoChangedWithExtensions`
that is easier to extend in the future because it does use an `Bundle` rather than
primitives. A `Bundle` can be changed in a backward/forwards compatible way
in case we need further changes.
The compatibility handling is provided in `MediaSessionStub` and `MediaControllerStub`. The approach is not based on specific AIDL/Binder features but implemented fully in application code.

If there is output data available (outputBuffer.hasRemaining()), then
there is no need to move other data between the underlying processors.
It will not change the buffer being returned by that call to getOutput.
If there is no output data readily available, it's necessary to go to
the AudioProcessors and pass buffers between them, as this may produce
data for output.

Previously, FrameProcessor never had the usecase in which the output surface
is replaced, while previewing introduced this usecase.
When switching output surfaces, we need to destroy the EGL Surface linked to the
surface that is being swapped out, because an EGL surface is linked to the EGL
display (which is not destroyed even when releasing FrameProcessor).
A GL exception will be thrown in the following scenario if we don't destroy the
EGL surface:
1. Creates a Surface, the surface is identified by address 0x11
2. Sets Surface(0x11) on FrameProcessor. Eventually an EGL surface is created
to wrap Surface(0x11)
3. Release FrameProcess, this releases the EGL context
4. Instantiate a new FrameProcessor, sets Surface(0x11) as the output
5. When FrameProcessor creates an EGL surface to wrap Surface(0x11), GL throws
an exception, becasue Surface(0x11) has previouly been connected to an EGL
surface.

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.

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.

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.

Currently, a frame is dropped if it's requested release time is in the past.
This mode was added to support previewing. However, in normal ExoPlayer
playback, slightly late frames (<30ms late) are also rendered. On MediaCodec
side, this means calling `releaseOutputBuffer` with a release time in the
past.
PiperOrigin-RevId: 479615291
This mode is supported by using `C.TIME_UNSET` (which is a negative value). The
new logic decouples the value of `C.TIME_UNSET` and the frame dropping
behaviour.
PiperOrigin-RevId: 479368880
Currently `FrameProcessor.releaseOutputFrame()` method supports
Release at a specific system time
Drops the frame
This API is not that convenient to use when the caller wants to release a frame, now, regardless of the release time. A use case is to release (present) a frame when no frame is shown for a while, and it's thus better to just release the frame, now.
Currently if MCVR wants a frame to be rendered now, MCVR calls release frame with a set offset like 10us: `releaseOutputFrame(System.nanoTime() + 10_000)`. The 10us offset is to prevent the frame processor dropping the frame, due to thread hopping delays.
To make the API better usable, consider adding a mode for releasing the frame now, like (bold marks the new mode)
- Use C.TIME_UNSET to drop
- **Use -1 to release the frame immediately, or**
- Use an actual release time.

A follow up to stopping speaker playback with a Player decorator from
https://github.com/androidx/media/issues/15.
It looks like we will need to change to using playback suppression to avoid
errors like https://github.com/androidx/media/issues/167, when we don't start
a foreground service.
We may not have this implemented by 1.0, but would like it in the API and it seems to be appropriate.

"Final" was likely added to reference the FinalMatrixTextureProcessorWrapper,
which is a package-private class. However, I think more clear to express that
this is the input size, which then has all effects applied, to get the output
size.

* Before this CL, the texture was stored during the construction of the LUT processor. This failed since if one creates a list of GlEffects on the application thread, the texture will get stored in the application thread during the effect creation and not on the GL thread, which executes the FrameProcessors.
* This is an issue since the executing thread then can't index from the texture stored on a different thread.

The stream offset is used to calculate the presentation time of
a metadata object when reading and later when playing, to calculate
the current presentation time to decide whether to send the metadata
to the output.
Accordingly, the presentation time of a pending metadata that has been
calculated with a given offset needs to be recalculated when the
stream offset changes.

In particular, make it a bit more clear that "rendering" and "releasing" frames are
related concepts, and how they differ from one another in conjunction with frame
dropping.

Use the PQ OETF and EOTF to ensure that intermediate fragment shader operations
using PQ are in linear BT.2020 rather than PQ and HLG-1 BT.2020.
Also, swap the OETF and EOTF in shaders, as they were used incorrectly before
Manually tested by verifying transformer demo HLG and PQ videos look the same with and without this CL, including with a BitmapOverlayProcessor enabled to test flows both with one MatrixTransformationProcessor that skips HDR TFs, and with one that doesn't.

Adds a method to FrameProcessor.Listener to be called when an
output frame is available and a method releaseOutputFrame in
FrameProcessor allowing the caller to trigger release of the
oldest available output frame at a given timestamp. Late frames
or frames with unset release times are dropped in the
FinalMatrixTransformationProcessorWrapper.
More than one output frame can become available before they are
released if the penultimate GlTextureProcessor is capable of producing
multiple output frames. Processing continues while waiting for
releaseOutputFrame to be called. Frame release tasks are prioritized
over other tasks.

While HDR is most closely tied to the color transfer (ex.
COLOR_TRANSFER_SDR is the only one explicitly mentioning dynamic
range), technically color spaces may be associated with HDR as well,
like BT.2020 commonly being used for HDR rather than BT.709 for SDR.
Therefore, it's more specific to mention just that the transfer is HDR.

This allows the GlEffectsFrameProcessor to later handle HLG and PQ
differently, or limited and full color range differently.

Format.NO_VALUE is a placeholder value for an invalid @C.ColorTransfer, used
for example when the decoder doesn't support this transfer function.
When encountering this invalid value, interpret this as COLOR_TRANSFER_SDR.
Confirmed locally that an exception is thrown when transcoding on p4head, and no exception is thrown when transcoding with this CL.

they depend on) without depending on transformer or the
