I recently found out that mpv was stuttering when i used it on my old Intel Pineview Atom box because the normalisation audio filter munched all the CPU time. I wondered if i could load a profile according to the CPU used, and finally managed to do it.
I thought that it would be integrated with the profile-desc=cond:some_lua_code helper,
but it did not work at all.
So at first,
in my ~/.config/mpv/mpv.conf,
i defined options for the default profile,
then the Atom specific profile,
with youtube-dl options as a goodie:
# Better youtube quality on higher specced machines ytdl-format=best[height<=?1080] # Normalize the audio output af=loudnorm=I=-15 [atom] # Reduce youtube quality on that slow Atom box ytdl-format=best[height<=?360] # And clear the normalization audio filter (it uses a lot of cpu) af=
mpv has lua scripting capabilities that will be required to make the profile autoloading work. As expected, if the CPU model is an Atom, it will apply the "atom" profile.
$ cd ~/.config/mpv
$ mkdir scripts
$ cat > scripts/autoprofile.lua
h = io.popen("sysctl hw.model")
v = h:read("*a")
h:close()
if string.find(v, "Atom", 1, true) ~= nil then
mp.commandv("apply-profile", "atom")
end
^D
You can check out if everything is correct with mpv -v [...]. Enjoy :)
