Function to restart mpv by pressing the key.

restart_mpv.lua

-- When using the version under development, the image sometimes
-- freezes during seek. Restarting mpv cures it, but it is
-- troublesome, so I wrote a script to solve the problem.

   local cmds = {"run", "mpv"}

   -- local opts = mp.get_property_native("property-list")
