hdr10plus_tool

CLI utility to work with HDR10+ in HEVC files.
Previously named hdr10plus_parser, now it's more than just a parser.  

Options that apply to the commands:

• --verify Checks if input file contains dynamic metadata.
• --skip-validation Skip profile conformity validation. Invalid metadata is set to profile N/A.

Commands

• extract

  Extracts the HDR10+ metadata from HEVC SEI messages to a JSON file.
  Also calculates the scene information for compatibility with Samsung tools.

  If no output is specified, the file is only parsed partially to verify presence of metadata.

  Examples:

  • hdr10plus_tool extract video.hevc -o metadata.json
  • ffmpeg -i "input.mkv" -map 0:v:0 -c copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_tool extract -o metadata.json -
  • Extract without validating: hdr10plus_tool --skip-validation extract video.hevc -o metadata.json  

• inject

  Interleaves HDR10+ metadata NAL units before slices in an HEVC encoded bitstream.
  --verify has no effect with this command.

  • Example: hdr10plus_tool inject -i video.hevc -j metadata.json -o injected_output.hevc
