The matrix provider allows the transformation matrix to be updated
for each frame based on the timestamp.

The following example effects using this were added to the demo:
* a zoom-in transition for the start of the video,
* cropping a rotating rectangular frame portion,
* rotating the frame around the y-axis in 3D.

We add an entire class like we do for parsing other codec initialization formats; it's currently not doing any parsing though (... initialization data is really simple for AV1 though: just the entire contents of the box).

For testing, we add the sample file, having been re-encoded with ffmpeg (and we also happen to have another av1 file, too).

This makes it more clear to users of the demo that this is only available under API 31.

Some RTSP servers use `npt`: notation rather than `npt=`

This allows apps to use AdvancedFrameProcessor to apply transformations
in 3D space. This functionality is not used in transformer otherwise.

The encoder surface is no longer needed for the OpenGL setup and frame
processor initialization, as a placeholder surface is used instead. So
all of the setup can now be done in the factory method.

App code should get all of this information from TrackGroupInfo,
and should only need TrackGroup as a key to use for overrides.

This is based on the ExoPlayer form:

Also force people to use one of the templates.

This allows the MuxerWrapper to keep using trackTypeToTimeUs for
calculating the video duration but slightly changes the meaning of
its interleaving constraints.

This provides better compatibility with MediaExtractor, which does read these fields; we also need them for being able to mux file contents into another mp4 file.

Also, there is a minor refactor included so that we have an actual type for esds box contents instead of a pair.

The encoder factory will be used in other tests.

This makes it easier (smaller CL diff) to merge output size
configuration and initialize() in a follow-up.

The placeholder surface is either EGL_NO_SURFACE or a 1x1 pbuffer
depending on whether the device supports EGL_KHR_surfaceless_context.

Since the output textures and surfaces are managed by the
FrameProcessorChain, clearing them there makes sense.
This is also less error-prone as it might not be obvious to
someone implementing a GlFrameProcessor that they need to
glClear. (Clearing twice won't cause any problems.)

This is basically 'container' and 'subtitle' MIME types

I previously avoided stabilising any 'custom' MIME types (those
containing '/x-') but it certainly seems reasonable to expect
developers to use APPLICATION_M3U8 and so then it also makes sense
to stabilise other 'similar' custom MIME types too.

This change adds the ability to update the error code of the PlaybackStateCompat in
cases we need this for backwards compatibility. It is applied in the least
intrusive way because normally, return values of a service method should not change
the state of the `PlaybackStateCompat`, just because it has nothing to do with the
playback state but rather with the state of the `MediaLibrarySession`.

For this reason only the error code `RESULT_ERROR_SESSION_AUTHENTICATION_EXPIRED`
is taken into account while all other error codes are not mapped to the
`PlaybackStateCompat'.

This requires an additional nanos to micros conversion because
the SurfaceTexture uses nanos. But as the timestamps from the
MediaCodec decoder (propagated in DefaultCodec#releaseOutputBuffer) are
in microseconds no precision is lost here.

Also add test that checks output video duration.

MAXIMUM_AVERAGE_PIXEL_ABSOLUTE_DIFFERENCE was copied from a test
class, but BitmapTestUtil isn't a test. So the javadoc needs
rewording to reflect that.
