customise_font

A script for MPV that allows you to modify the font easily, cycling between your favourite fonts. Supports scaling for PlayRes, adding LayoutRes, and only modifying the default font. Saves your changes as well.

Installation

Git clone the repository inside your scripts folder.

Usage

To add your own fonts and custom styles without them being overwritten when updating the script, create a file named custom-styles.lua in the script's directory and add your font styles there.

Example custom-styles.lua:

return {
    "FontName=Netflix Sans,PrimaryColour=&H00FFFFFF,OutlineColour=&H00000000,BackColour=&H00000000,Bold=-1,Outline=1.3,Shadow=0,Blur=7",
    "FontName=Gandhi Sans,Bold=1,Outline=1.2,Shadow=0.6666,ShadowX=2,ShadowY=2",
    "FontName=Trebuchet MS,Bold=1,Outline=1.8,Shadow=1,ShadowX=2,ShadowY=2",
    ""
}

After doing that, simply press k to cycle forwards, K to cycle backwards, and Ctrl+k to cycle between Normal and Smaller font. You can also press Ctrl+r to reload the config and apply any modifications you made to custom-styles.lua on-the-fly. You can change these controls in the script:

mp.add_key_binding("k", "cycle_styles_forward", function() cycle_styles(1) end)
mp.add_key_binding("K", "cycle_styles_backward", function() cycle_styles(-1) end)
mp.add_key_binding("Ctrl+k", "toggle_font_size", toggle_font_size)
mp.add_key_binding("Ctrl+r", "reload", reload)

After using, it will generate a .conf file in your script-opts, to save the changes you make.

How it works

The disadvantage of simply using an override, is that it won't work on all files. This is because not all files have the same PlayRes. To fix this, we can simply get the PlayRes it uses, and divide it by the default PlayRes values. This gives us a scale factor that we can use to multiply the overrides values.

For guessing the default font, first it uses a heuristic approach, trying to guess it by the most popular font + size combination, then it uses ffmpeg to analyse 2 minutes of the anime.
