  • Input: DolbyVision
    • Output:
      • DolbyVision and SDR
      • HDR10 and SDR
  • Input: HDR10
    • Output:
      • HDR10 and SDR
      • HLG and SDR
  • Input: HLG
    • Output:
      • HLG and SDR
      • HDR10 and SDR
  • Input: SDR
    • Output:
      • HDR10 and SDR
      • HLG and SDR

If you want to load a DolbyVision metadata as a sidecar XML file, the following parameter also needs to be specified. If that parameter is not provided for a DolbyVision encoding, the example assumes the corresponding metadata is embedded into the DolbyVision input mezzanine file itself.

  • HTTP_INPUT_DOLBY_VISION_METADATA_FILE_PATH (?)
