HDR tone-mapping with mpv


Best Answer Doofus , 19 March 2019 - 09:45 PM

Here's a starter pack for those who haven't done this, before. This assumes that your desktop coloring looks like a standard desktop. This is important!

1. Download the Adobe attachment, and unzip it to; C:\Windows\System32\spool\drivers\color

2. Download the mpv config attachment, and unzip it to; %AppData%\Roaming

 

3. Replace mpv with the March 10 2019 build 64 bit or 32 bit

 

    Just download it and unzip it to; %AppData%\Roaming\Emby-Theater\system\x64\mpv

 

4. Go play a movie :)

Any questions, ask them, here :)

 

(more information and an updated configuration, can be found here)

@Doofus, what are your windows display settings with hdr enabled? i can only get 8-bit dither rgb when i set my display to 3840x2160 60hz altho my radiance pro shows the input signal as 3840x2160 60 hz, 444-hdr2020... thanks!


HDMI 2.0 doesn't support RGB 10 at 60hz. That's why I asked what GPU you have. You either need to lower the refresh to below 30Hz or use chroma sub-sampling, which you need a discrete GPU to be able to do that.

Rgb 10 at30hz works fine for my setup gt1030

if you use something like an hdfury vertex it's easy to force a change in the pc's integrated graphics chroma sub-sampling simply by changing the edid  the vertex reports, for example 3840x2160 60hz 10-bit, ycbcr420 is easily achieved (shown in the  pc's advanced settings)... but, yes, without a 1.4 displayport out or hdmi 2.0a out, something that will handle a bandwidth of 18gps+, which my pc doesn't have, i won't be able to get anything higher than 8-bit with 3840x2160 60hz rgb.

 

anyway, not sure where i'm going to go from here, will continue to keep my eye on mpv hdr progress but for the time i'm thinking of going in a different direction... that said, thanks for all of the info on the subject you've provided!
