Where to customize OSC font size in osc.lua?

[pglpm]

On my hi-dpi screen, the OSC font size is too small when playing audio files. But I like the standard OSC otherwise.

From this discussion and this discussion, I understand that I can customize the OSC font by launching mpv with --no-osc (or adding a corresponding setting in mpv.conf), and putting a custom osc.lua in the /scripts folder.

So I did exactly that, copying the standard osc.lua in my /script folder.

My question: where exactly in osc.lua do I change the various OSC font sizes? I have no knowledge of LUA files. I tried changing various //fs... parts there, but they seem to have no effect.

Much grateful for help and hints!

The font sizes are set in this function.
Each element has a different font size.

The font size is the number after \\fs
You just need to change the number.

local function set_osc_styles()
    osc_styles = {
        bigButtons = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.buttons_color) .. "\\3c&HFFFFFF\\fs50\\fn" .. icon_font .. "}",
        smallButtonsL = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.small_buttonsL_color) .. "\\3c&HFFFFFF\\fs19\\fn" .. icon_font .. "}",
        smallButtonsLlabel = "{\\fscx105\\fscy105\\fn" .. mp.get_property("options/osd-font") .. "}",
        smallButtonsR = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.small_buttonsR_color) .. "\\3c&HFFFFFF\\fs30\\fn" .. icon_font .. "}",
        topButtons = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.top_buttons_color) .. "\\3c&HFFFFFF\\fs12\\fn" .. icon_font .. "}",

        elementDown = "{\\1c&H" .. osc_color_convert(user_opts.held_element_color) .."}",
        timecodes = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.timecode_color) .. "\\3c&HFFFFFF\\fs20}",
        vidtitle = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.title_color) .. "\\3c&HFFFFFF\\fs14\\q2}",
        box = "{\\rDefault\\blur0\\bord1\\1c&H" .. osc_color_convert(user_opts.background_color) .. "\\3c&HFFFFFF}",

        topButtonsBar = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.top_buttons_color) .. "\\3c&HFFFFFF\\fs18\\fn" .. icon_font .. "}",
        smallButtonsBar = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.buttons_color) .. "\\3c&HFFFFFF\\fs28\\fn" .. icon_font .. "}",
        timecodesBar = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.timecode_color) .."\\3c&HFFFFFF\\fs27}",
        timePosBar = "{\\blur0\\bord".. user_opts.tooltipborder .."\\1c&H" .. osc_color_convert(user_opts.time_pos_color) .. "\\3c&H" .. osc_color_convert(user_opts.time_pos_outline_color) .. "\\fs30}",
        vidtitleBar = "{\\blur0\\bord0\\1c&H" .. osc_color_convert(user_opts.title_color) .. "\\3c&HFFFFFF\\fs18\\q2}",

        wcButtons = "{\\1c&H" .. osc_color_convert(user_opts.buttons_color) .. "\\fs24\\fn" .. icon_font .. "}",
        wcTitle = "{\\1c&H" .. osc_color_convert(user_opts.title_color) .. "\\fs24\\q2}",
        wcBar = "{\\1c&H" .. osc_color_convert(user_opts.background_color) .. "}",
    }
end

You may also want to try to scale the whole OSC, and see if that works better for you.

e.g., change:

 scalewindowed = 1,        
 scalefullscreen = 1,

to:

 scalewindowed = 1.5       
 scalefullscreen = 1.5
