Other Information

- Windows version: Version	10.0.26100 Build 26100
- GPU model, driver and version: 4060 576.52
- Source of mpv: https://api.github.com/repos/zhongfly/mpv-winbuild/releases/latest according to the update.ps1
- Latest known working version: none
- Issue started after the following happened: i compared an iamge and noticed a massive color difference with profile=high-quality vo=gpu-next and nothing else.

after that i tried the very old know calibration patterns from https://www.avsforum.com/threads/avs-hd-709-blu-ray-mp4-calibration.948496/

Reproduction Steps

mpc-hc is madVR mpc-be is mpcVR
mpv decodes this files as 255 15 3.
a bit difference is fine dithering such but that not even close to 100% red
mpcVR pixel i checked is 255 1 0
madVR is 255 0 0

tested file
https://github.com/user-attachments/assets/fb0e9e0d-3b5c-40e8-8709-bd7b17214675

i could not test no config because it is again blank

Expected Behavior

if the file is correct red 255 so ~241 CB mpv should also produce red like any other renderer/video player else the rest is wrong and the file is 255 15 1 and i have a lot more bug reports to write...

Actual Behavior

mpv outputs 255 15 1 instead of 255 0 0

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

[dyphire]

I can't reproduce it completely.
In my tests, mpcvr outputs (255, 0, 0) and mpv outputs (255, 1, 0).
But it can be confirmed that the color output of mpv may be inaccurate.

[mightyhuhn]

that's to be expect that's just dither noise the result i have is far outside of that. you can not reproduce the issue then.
dither a 0 to a 1 shouldn't happen in an perfect world but in terms of math that's not odd.

[dyphire]

that's to be expect that's just dither noise the result i have is far outside of that. you can not reproduce the issue then. dither a 0 to a 1 shouldn't happen in an perfect world but in terms of math that's not odd.

Do you have an icc file applied to your system? When I use icc for color management the color output of mpv is way off, similar to your test.

[mightyhuhn]

i checked that already but that was changed in win 11 and there seems to be none. i'm not used to the new menu.
if there is one madVR nore displaycal isn't cable of reading that type and i only used displayCal to calibrate.

[hooke007]

1 unit shift could be caused by deband too.

[mightyhuhn]

i have added deband=no nothing changed
the mpv option doesn't list this as an option but ` does not complain about wrong syntax so it should work? i also can't find deband as an option under I 2 so it shouldn't run. what so ever the error i'm having is 15.

should D:\mpv-x86_64-v3-20230716-git-cab5448>mpv.exe --version really be blank ever?

[hooke007]

It's (255, 1, 0) here with no-config, while (255, 0, 0) with adding dither=no (edit: Emm, --cscale=bilinear is also required.).

[NSQY]

@mightyhuhn Can you open the file with mpv, press SHIFT + I and take a screenshot. I get a polluted output rgb(255, 18, 7) on my wide gamut display if I do not properly set --target-prim

[mightyhuhn]

cscale=bilinear does not matter here it is still doing ~255 15 3 here

@mightyhuhn Can you open the file with mpv, press SHIFT + I and take a screenshot. I get a polluted output rgb(255, 18, 7) on my wide gamut display if I do not properly set --target-prim

sure:

edit GPU-next:

/edit
my display is a S90C which is wide gamut but i run it in SDR mode.
as long as you are using SDR target-prim shouldn't be needed shouldn't it?

[NSQY]

should D:\mpv-x86_64-v3-20230716-git-cab5448>mpv.exe --version really be blank ever?

No. There is something wrong with the latest zhongfly, mpv.exe --version is blank for me also.

This should be the output:

mpv --version

same issue still blank. what so ever not the topic here just wanted to make sure i at least tried to follow instructions.
thanks for confirming.

on a side note. there is a difference between using mpv.exe and mpv.com. the latter (mpv.com) is the CLI wrapper and the former is the GUI application, i believe. so you either have to call mpv --version (without .exe, uses mpv.com) or mpv.com --version.

my display is a S90C which is wide gamut but i run it in SDR mode.
as long as you are using SDR target-prim shouldn't be needed shouldn't it?

By default mpv should not be trying to do anything to BT.601 and BT.709, unless you have --target-prim set to something else or an ICC profile applied.
