    • 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.

    • Fix error in frame rate handling. · 379ecd19 
      The old getString() will throw because FRAME_RATE can only be float or int.

    • Find only REGULAR_CODECS in EncoderUtil. · e0752a3a 
      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 · 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.

    • Fix MIDI command timestamp calculations and synthesization duration. · 8b0fe168 
      - 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).
