    • Only apply a MediaFormat-generated ColorInfo if it's valid. · 82e1eda4 
      Otherwise, invalid ColorInfo instances generated using faulty
MediaFormat#getInteger values could cause exceptions.

Confirmed that b/239435670 reproduces without this CL, and does not reproduce
with this CL.

    • Add fail-fast null checks to the stable Player API · d5e0c759 
      This will help developers self-diagnose issues like Issue: google/ExoPlayer#10392
where the NPE occurs far from the original null value because a field
gets assigned to null.

This change aims to ensure that every stable method on Player,
ExoPlayer and ExoPlayer.Builder that takes a non-null type will fail
with an NPE before returning.

    • Use Futures for MediaSession command queue instead of Runnables · 481205a8 
      Some commands may be asynchronous and subsequent commands need to
wait for them to complete before running. This change updates the
queue to use (and listen to) Futures instead of calling Runnables
directly. The commands are currently still added as Runanbles
though, so this change is a no-op.

Also moves the permission check in MediaSessionImpl to before
queueing the command because the permission should be check at
the time of calling the method.

When executing the comamnds in the queue, we need to be careful
to avoid recursion in the same thread (which happens when both
the Future is immediate and running on the correct thread already).
To avoid recursion, we detect this case and loop the commands
instead.

    • 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.

    • Fallback to SDR if encoder doesn't support HDR (HLG only). · 3bdecf2a 
      If the input is HDR (HLG), check encoder capabilities for HDR support
and request tone-mapping to SDR during decoder configuration otherwise.
Capabilities are only checked for API 31 and above, as HDR editing is
not supported before.

As the encoder capabilities check needs to happen before selecting the
encoder to use (as this may depend on the resolution output by the
effects chain), the EncoderWrapper checks all candidate encoders
for the MIME type for HDR capabilities and only requests fallback to
SDR if none of them support it.

When the actual encoder is selected, the wrapper checks that it matches
one of the encoders is checked capabilities for.

    • HDR: Configure GL shaders and encoder. · 28cf112e 
      Configure the GL shaders and encoder to take in HDR metadata.

This mostly just consists of passing the Format.colorInfo through
the VideoTranscodingSamplePipeline down to the encoder, rather than passing
the PQ-ness down to the GL step.

Due to b/237674316, this will remove HDR10+ support temporarily to introduce
support for HLG10.

Manually tested to confirm that HLG10 operations that don't affect color display
correctly after this CL with "HDR editing" in the demo checked, and continue to display incorrectly (as before this CL) without the option unchecked.

    • Round the frame rate in MediaFormat · f2b4701e 
      Although MediaCodec claims supporting float frame rate, encoder init failed on
API21 Nexus 5. Since it's just a performance hint to the codec, it's OK to
generalize it to other API versions.

      - Improve variable naming to include time units for clarity
- Fix existing timestamp calculations to respect time units as well as track tempo (default values for now)
- Ensure the synthesizer produces PCM for the correct amount of time (including gaps between commands).
