Convert HDR10+ to HDR10?

[chros]

Is there any util that can convert/mux HDR10+ to HDR10? If so, how?

Why: Oppo 203/205 player can convert HDR10(+) into LLDV on the fly, but the colors are way off with HDR10+ content, but not with HDR10 (probably a bug in the player).

Thanks

I found 1 HDR10 content where the issue is there, so it's not strictly HDR10+ related (although it's present with all HDR10+ content I tried).

I don't know if this will help you or not.

.
Do you know how to list all the video properties of a file with ffmpeg?

ffprobe -hide_banner -loglevel warning -select_streams v -print_format json -show_frames -read_intervals "%+#1" -show_entries "frame=color_space,color_primaries,color_transfer,side_data_list,pix_fmt" -i "input.mp4"

ThanksHow do you know the colours are way off? What make and model of HDR10+ TV do you have?

It's easy, just fire up the HDR10(+) version :)
It's LG OledB8 (in my signature).

Thanks, I'll try it. I hoped it allows to see/modify more properties, but it's a start :)

LG televisions don't support HDR10+ and wont be upgraded to do so as they are not on the HDR10+ adopters (https://hdr10plus.org/adopters/) list!

If you want to view HDR10+ video correctly with your OPPO UDP20x player, you'll need to get hold of a swanky new television from a manufacturer that also supports HDR10+. Such as: Loewe, Panasonic, Samsung, TLC, Toshiba, Vestel or Vizio.

EDIT: Also, your Yamaha RX-A870 AVR does not support HDR10+ either. So if you decide to buy a swanky new HDR10+ compatible television, don't connect your AVR between your OPPO and new television...

HDR10+ is really just HDR-10 with dynamic metadata. A file/stream should play just fine as HDR-10 on devices that don't know how to use the HDR10+ metadata. No conversion required.

He's already been told this (https://forum.doom9.org/showthread.php?p=1920974#post1920974)... But for some reason wanted to take the conversation to a new place :scared:

I've taken apart yusesope's script to make it only skip HDR10+ SEI NAL from whatever file, rewriting it untouched.
You can find it here: https://gist.github.com/quietvoid/175d7d16248848e2fb299f9eb1bd2c38

example: python hdr10plus_remove.py -i video.hevc -o processed_file.hevc

[chros]

Wow, quietvoid, I'll try it out and let you know!!! Thanks

[chros]

Thank You, I tried out with 1 HDR10+ file and the result works like a charm! :)

I had to install 'bitstring': pip install bitstring
After that:
- demuxed the streams with tsmuxer
- python hdr10plus_remove.py -i video.hevc -o processed_file.hevc
- remuxed the patched video stream and the audio stream with tsmuxer

You are supposed to present HDR10+ depending on the display capabilities. You can convert to multiple HDR10 per master curve.
