HDR10 Plus Metadata Extraction

You will have to download a copy of hdr10plus_tool from quietviod’s.

Verify HDR10+ metadata exists

Check to make sure your video has HDR10+ information it can read.

ffmpeg -loglevel panic -i input.mkv -map 0:v:0 -c:v copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_tool --verify extract -

It should produce a nice message stating there is HDR10+ metadata.

Dynamic HDR10+ metadata detected.

Once you confirmed it exists, extract it to a json file

ffmpeg -i input.mkv -c:v copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_tool extract -o metadata.json -
