1. Install FFmpeg.
2. Place sidebarsubtitles folder into your scripts directory.

MPV Default

I’m not planning to shrink the controls for the default theme, please use uosc.

Editing uosc

If you are using uosc, open uosc/main.lua, and follow these steps to shrink the player controls:

# find:
    if real_width <= 0 then return end

# add below:
	local temp_width = real_width
	if sidebarsubtitles_width and sidebarsubtitles_width > 0 then real_width = sidebarsubtitles_width end



# find:
    Elements:update_proximities()
    request_render()

# add below:
	if sidebarsubtitles_width and sidebarsubtitles_width > 0 then
	display.width, display.bx = temp_width, temp_width
	end



# find:
--[[ MESSAGE HANDLERS ]]

# add below:
mp.register_script_message("sidebarsubtitles", function(value)

	sidebarsubtitles_width = tonumber(value)
end)
