This is safer because it will prevent any future problems with
creating a new FrameProcessorChain before the previous one has
completed its async release.

From [eglDestroyContext documentation](https://www.khronos.org/registry/EGL/sdk/docs/man/html/eglDestroyContext.xhtml):
"If the EGL rendering context is not current to any thread,
eglDestroyContext destroys it immediately."
The context isn't current to any thread here because GlUtil calls
eglMakeCurrent with EGL_NO_CONTEXT before calling eglDestroyContext.
So everthing should be released once the FrameProcessorChain's
release task terminates.

`Player.getCurrentTracksInfo` was renamed to `Player.getCurrentTracks` in
https://github.com/androidx/media/commit/83daa052cbffe0fc671151cb8f2b0145f0b0b984.

Negative and zero values should be disallowed.

Add a very short (1 second) video, so that some manual tests / prototyping,
including tests for the start and end of a video, encoder selection, or
changes applied to frames, can finish quickly.

* Group what's now many related test PNGs by moving them to their own directory.
* Move bitmap references to files where they're used, as each bitmap is only
used once each, except the original bitmap.

Scaling and rotation using ScaleToFitFrameProcessor may change the
the resolution and aspect ratio, so defaulting to the same as the
input is no longer accurate.

What a minimal implementation should include is now explained in the
interface javadoc while the method name reflects what the method does.

Transformer resolves to null when wrapped, this is a debug line
that was not removed.

signalEndOfInputStream makes more sense before isEnded and
getPendingInputFrameCount is related to registerInputFrame.

The stream with the mp3 track is added because

- We only encode to AAC
- We only encode when the source track is not AAC

Now that we have a way to force encoding, we no longer need the mp3 track.

The test asset is kept for later parameterized testing.

The MIME type was set to H265 to force transcoding. Now that we have an encoder
factory that forces encoding, switching back to H264 ensures the quality test
is conducted on more devices (those don't support H265 can be tested now).

However, H265 should be part of the quality test after we have proper mechanism
to skip test based on device capability.

The DefaultMediaNotificationProvider checks if a command is available
before putting the respective action in the notification.

The new demo GlFrameProcessor is based on BitmapOverlayVideoProcessor
from the gl-demo. The demo-only GlFrameProcessor can be deleted once
Transformer supports this functionality.

1/4 is probably unnecessary, as 1/3 of 4k is 720, which should be supported on
all practical encoders.

We don't currently have enough understanding of the correlation between a
specific SSIM score and video quality. Dropping to .90 to make most tests pass.
Especially when there's no discernible difference from the videos with .9 and
.95 SSIM.

PeriodicDimmingFrameProcessor is an example of how a custom fragment
shader can be used to apply color changes that change over time.

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).
