    • Ensure pending commands are still sent in MediaController.release() · 29246fb1 
      We currently clear all pending messages, including the one that flushes
pending commands to the MediaSession. To ensure all commands that have
been called before controller.release() are still sent, we can manually
trigger the flush message from the release call.

Related to handling the final flush because disconnecting the controller,
MediaSessionStub didn't post the removal of the controller to the
session thread, creating a race condition between removing the controller
and actually handling the flush.

    • Slightly disentangle `MediaBrowser/Controller(Impl)Base/Legacy` · 0667c74d 
      These constructors are currently very intertwined, passing `this`
references from the constructor of one to the constructor of another
before the first constructor is complete (and so the `this` reference
isn't really valid yet).

This change uses checker framework `@UnderInitialization` and
`@NotOnlyInitialized` annotations to make it more clear that the
references are not available yet. For the one 'direct' access needed
in the second constructor (calling `getApplicationLooper()`) we now
pass the `applicationLooper` directly alongside (to avoid needing to
dereference the reference 'too early').

This change also ensures that where a class hierarchy has a
'dependent' class hierarchy, the 'subclass' instance is always used
(by both subclass and superclass) without casting or manually hiding
the superclass field, by defining an overridable `getFoo()` method
instead and always using it.

    • HDR: Implement HLG EOTF and OETF. · 06d3c07a 
      This allows us to use BT.2020 RGB linear for intermediate shaders, which also
allows us to re-enable PeriodicVignetteProcessor, which should work properly in
linear color-spaces.

Manually tested by adding a GlEffectsWrapper, and confirming that HLG HDR editing still looks correct.

    • Rename seq to sequenceNumber in MediaSessionStub · 33c5aa7a 
      "seq" is not a well-defined abbreviation and the value is
also an integer, so sequenceNumber is better than just sequence.

    • Make DefaultMediaNotificationProvider more configurable · 62a2d76d 
      Add a Builder to constructor DefaultMediaNotificationProvider. The
Builder can also set the provider's:
- notification ID
- notification channel ID
- notification channel name

The change adds an API for apps to set the small icon in notifications.

    • Run MediaSessionStub commands in order · eb823a9a 
      Some commands are run asynchronously and subsequent commands need
to wait until the previous one finished. This can be supported
by returning a Future for each command and using the existing
command execution logic to wait for each Future to complete.

As some MediaSessionStub code is now executed delayed to when it
was originally created, we also need to check if the session is
not released before triggering any actions or sending result codes.

    • Properly chain commands in MediaSessionStub · d84662e5 
      The commands currently use a task and a postTask that are chained
together manually. In some cases, e.g. when adding MediaItems,
the postTask is already a chain of commands in itself.

To allow using the entire command handling as a single task
(for simplified queueing), we can change the implementation to
always create a single task. If multiple subtasks need to be
chained together, we can do that by wrapping the method calls.
In case a task is asynchronous, we can also use Futures to
chain them together.

Overall, this is just a refactoring and changes no logic.

    • HDR: Use FP16 color representation for texture processors. · 54cdec46 
      * Introduced `useHdr` for `GlEffect#toGlTextureProcessor`, so
  `TextureProcessor` implementations can decide how to handle HDR.
* Creating FP16 color textures for HDR input.

Tested via manual testing, adding a no-op GlEffectWrapper to the transformation to
force use of intermediate textures, adding a linear ramp to the fragment shader,
and trying to ascertain that there's a real reduction in posterization when
switching from 4-bit to 8-bit unsigned bytes, and again from 8-bit unsigned bytes
to 16-bit floating point.

    • HDR: Throw when unexpected color transfer encountered. · add44470 
      This may happen when a containers' color transfer incorrectly does not match
the video's color transfer.

An example of a file with such a mismatch is the current Transformer demo HDR10
sample file.

Manually tested by confirming that no errors are emitted for SDR and HLG sample
files, and that errors are emitted for our incorrect HDR10 sample file.

    • Implement getCurrentTracks in MediaController · 24bfe3a5 
      After this change the current tracks are sent to the controller as part of
`PlayerInfo` and call `Listener.onTracksChanged()` in case of a change in tracks.

    • Make minor fixes to HDR handling · 04fa2fda 
      - Update profile selection logic to pick an HDR-compatible profile when doing HDR editing on H.264/AVC videos.
- Handle doing the capabilities check for all MIME types that support HDR (not just H.265/HEVC).
- Fix a bug where we would pass an HDR input color format to the encoder when using tone-mapping.
- Tweak how `EncoderWrapper` works so decisions at made at construction time.

Manually tested cases:
- Transformation of an SDR video.
- Transformation of an HDR video to AVC (which triggers fallback/tone-mapping on a device that doesn't support HDR editing for AVC).
- Transformation of an HDR video with HDR editing.

    • Update demo HDR10 video URL · c4e64c3d 
      The old URL doesn't correctly signal the HDR10 color info in the container.

The new URL signals ST2084 (PQ) transfer function and BT.2020 color space as expected.
