Using a custom mpv.conf for Shaders and Dynamic Tone Mapping?

[makin__ 0]

Hi everyone,

I just switched from Kodi and MPV as the external player to Emby as I really love the concept. However, I would like to use my own mpv.conf so I can set certain shaders and picture quality settings such as the hdr->sdr dynamic tone mapping (using spline) etc.

 

I tried to set up the mpv.conf at %appdata%\mpv\mpv.conf but it is ignored. 

Can you guys help me?

Thanks a lot

The mpv.conf should be in the mpv folder, not its own folder

Thanks for answering. The config I use for mpv is stored at mpv/portable_config/mpv.conf <- this one is not used by Emby Theater.

[generiq 258]

It has to be in the mpv folder. The portable folder will isolate it from Theater,.

Ok cool! Anything else to keep in mind regarding what can be set up in the config to not interfere with Theater?

[generiq 258]

Some options will be overridden by the options in Theater. Such as the gpu-api and hardware acceleration. But for hardware acceleration,  there is an option to let the conf set it.

Ok, great. It's mainly HDR settings like:

[HDR-Spline]
profile-desc="HDR ST2094-10"
profile-cond=p["video-params/primaries"]=="bt.2020"
tone-mapping=spline
target-peak=auto
target-trc=auto
hdr-compute-peak=yes
allow-delayed-peak-detect
builtin-scalers
deband=no
tone-mapping-param=default
gamut-mapping-mode=relative
target-contrast=auto

And:
 

# Scaling
scale=ewa_lanczossharp # luma upscale
dscale=mitchell # luma downscale
cscale=ewa_lanczossharp # chroma up&downscale
scale-antiring=0.4 # luma upscale deringing
dscale-antiring=0.4 # luma downscale deringing
cscale-antiring=0.4 # chroma upscale deringing
correct-downscaling=yes
linear-downscaling=yes
#sigmoid-upscaling=yes
gpu-shader-cache-dir="C:\Program Files\mpv-x86_64\portable_config\shaders_cache"
glsl-shader="C:\Program Files\mpv-x86_64\portable_config\shaders\KrigBilateral.glsl"
glsl-shader="C:\Program Files\mpv-x86_64\portable_config\shaders\SSimDownscaler.glsl"
#glsl-shader="C:\Program Files\mpv-x86_64\portable_config\shaders\adaptive-sharpen.glsl"

See any problems?

[generiq 258]

Most of that should be fine, just make sure that corresponding options in Theater are disabled, and leave everything else on auto except for video output. Choose gpu-next.

Just tried it and with the mpv.conf in C:\Program Files (x86)\mpv, it still does not work. Where can I find the logs to see whether Theater is at least trying to? 

Is there another mpv folder? What would have been if mpv wasn't installed in the first place? Theater must have mpv integrated somehow doesn't it?

What about C:\Users\makin\AppData\Roaming\Emby-Theater\system\electronapp\libmpv\x64?

I just stumbled upon this post here. In my initial post I mentioned that I tried C:\Users\makin\AppData\Roaming\mpv\mpv.conf at first.

I created the mpv.log file and it gets filled:

 

mpv.log

[generiq 258]

How do you know it isn't working?

[generiq 258]

It looks like you've installed Theater here:

C:\Users\kodi\AppData\Roaming

So your mpv folder should be there, under that username

[generiq 258]

It's reading auto profiles from somewhere 

[   0.866][v][cplayer] Applying profile 'HDR'...
[   0.866][v][cplayer] Setting option 'target-trc' = 'auto' (flags = 4)
[   0.866][v][cplayer] Setting option 'target-peak' = '120' (flags = 4)

 

[generiq 258]

Make sure you don't have conflicting mpv.conf files. You should have one in your mpv folder for one user and one in your portable.  No others

Sorry, my user is „Kodi“, I did not want to confuse so that’s why I posted another user name (makin). 
 

I guess input.conf does not work and the info in the nerd menu is not altered right? 

[generiq 258]

Inputs are handled by electron. And the Theater stats won't show shader activity or any profiles. You'll need to look at your mpv logs 

[makin__ 0]

Thank you so much. I got a plan for tomorrow then.
 

Any feedback regarding shaders?

 

Edited November 4, 2023 by makin__

[generiq 258]

What were you wanting to know? There are a multitude of shaders that have different functionality. 

Example:

https://github.com/natural-harmonia-gropius/hdr-toys/blob/master/gamut-mapping/clip.glsl

[makin__ 0]

Mainly whether I can use the same shaders and the spline tone mapping settings that I use in my Kodi+MPV setup.

[generiq 258]

You should be able to. You just need to keep up to date with developments. Not only with the shaders but also with what hassn is developing with libplacebo and the renderers. There's no simple answer to that. You're going to have to manage what you use and read a lot. There is so much development in this area right now.

I attached the mpv.log created after starting and playing back a movie (4K). It looks good so far. What do you think? See any issues in the log?

 

Thanks again for guiding me through everything, I really appreciate it.

Some of that won't have any effect, but shouldn't cause a problem. Post screenshots of the settings in Theater.

Sure thing:

Also, I could have sworn that before restarting the Emby Server, my Safari, Chrome ans iOS apps did not have to transcode (Audio), any idea what might cause this? ET does not have to...
