    • Ensure supported request only updates changes fields. · 59166cce 
      The TransformationRequest passed to FallbackListener (and
createSupportedTransformationRequest) can have null for values that
are inferred from source. Within fallback, this can be height, width,
video mime type and audio mime type (HDR mode is not linked to source).
requestedFormat has these values populated from source, and
supportedFormat then finds the closest supported values to the
requested.

If any of the values in supportedFormat do not match the
requestedFormat, then this method would build upon the
TransformationRequest and update ALL possible fallback fields. This is
a problem because the fallback listener compares the original request
to the fallback one and notifies about all the fields that have
changed.

This CL changes this so that only the values that are not the same as
requested are changed in the supported request that is given to the
fallback listener.

    • Fix AS warnings and errors in FloatAudioMixingAlgorithmTest · cad713d0 
      When trying to run the test on Android Studio, error "incompatible
types: Buffer cannot be converted to ByteBuffer" is logged. This is
because ByteBuffer.flip() returns a Buffer (and not a ByteBuffer).
Annotation @CovariantReturnType on ByteBuffer.flip() should resolve this
automatically but it doesn't seem supported at the moment.

    • Fix recursive loop when registering controller visibility listeners · 4087a011 
      There are two overloads of this method due to a type 'rename' from
`PlayerControlView.VisibilityListener` to
`PlayerView.ControllerVisibilityListener`. Currently when you call one
overload it passes `null` to the other one (to clear the other listener).
Unfortunately this results in it clearing itself, because it receives
a null call back!

This change tweaks the documentation to clarify that the 'other'
listener is only cleared if you pass a non-null listener in. This solves
the recursive problem, and allows the 'legacy' visibility listener to be
successfully registered.

    • Add error messages to correctness assertions in SimpleBasePlayer · 6c98f238 
      Users of this class may run into these assertions when creating the
State and they need to check the source code to understand why
the State is invalid. Adding error messages to all our correctness
assertions helps to understand the root cause more easily.

    • Simplify concurrency in FrameProcessingTaskExecutor · cb0bc28a 
      This CL replaces concurrent collections and atomic primitives with a single
lock, this way the code is easier to reason about.

    • HDR: Implement Transformer HDR to SDR GL tone-mapping API · 84c81b85 
      Note that we simply use GlEffectsFrameProcessor in-app / GL tone-mapping, so PQ->SDR tone-mapping isn't yet implemented.

Tested manually using the demo on Pixel 7, to confirm that device and in-app tone
mapping behave similarly.

    • Add low level audio mixing algorithms · 9465fe2f 
      Adds the AudioMixerAlgorithm interface which allows for specialized
implementations of audio mixing that also efficiently convert between
source and mixing formats.

Initial implementation has two algorithms:
1. Float -> float (with channel mixing)
2. S16 -> float (with channel mixing)
