HDR10+ to DoVi Conversion Issue #52

Closed synacktic closed 3 years ago

synacktic commented 3 years ago

The issue may be that it can't be done and I just misunderstood, but:

  1. I used the most recent binary of the hdr10 tool to export the hdr10+
  2. I used the most recent dovi_tool binary to convert the json into an RPU
  3. I injected the RPU back into the original file
  4. Looked at the media info for the file and I see HDR10+ listed, not DV

Commands run: ffmpeg -i hdr10plus_movie.mkv -map 0:v:0 -c copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_tool extract -o hdr10plus_metadata.json -

ffmpeg -i hdr10plus_movie.mkv -c:v copy -vbsf hevc_mp4toannexb -f hevc hdr10plus_movie.hvec

dovi_tool generate -j assets/generator_example.json --hdr10plus-json hdr10plus_metadata.json -o RPU_from_hdr10plus.bin

dovi_tool inject-rpu -i hdr10plus_movie.hvec --rpu-in RPU_from_hdr10plus.bin -o injected_output.hevc

So, am I doing something wrong or just wrong about the expected result?

Thanks for your time and a million thanks for your tools!

You need to mux the video in a compatible container for MediaInfo to show the Dolby Vision information. MKVToolnix, MP4Box and tsMuxer support this.

I tried that previously, but now that you mention it, I was probably not using the latest MKVToolnix. I'll update and try again

Yup, my boneheaded mistake using an old MKVToolnix, all is well now.

Thanks for the tools, very good stuff.
