    • Make minor fixes to HDR handling · 0e156891 
      - 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 · ce3cdf85 
      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). · 67439206 
      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. · 39047b56 
      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.

    • Fix error in frame rate handling. · b440b556 
      The old getString() will throw because FRAME_RATE can only be float or int.

    • Find only REGULAR_CODECS in EncoderUtil. · e3f1787c 
      We used "ALL_COOECS" previously, and it is not necessary because "ALL_CODECS"
additionally the codecs that support tunneling/secure decoding, which there
is no use case in Transformer.

    • Round the frame rate in MediaFormat · f1d4a4ca 
      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.

    • Fix MIDI command timestamp calculations and synthesization duration. · d03fb394 
      - 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).
