Mpv doesn't open any video files

I took your advice and loop from different video outputs. It seems to work with 3 of them: vdpau, xv and X11:

Check between vdpau and xv - those can be accelerated, but both have possible problems.
My guess is vdpau should provide slightly better experience if it works well enough … but see for yourself.

And then … go ahead and set your new default.

(maybe it could look like this, 2 in preferred order, with extra comma just in case:   vo=vdpau,xv, )

EDIT - scratch that … according to your output … it seems vdpau is having some issue - it might not seek properly or skip. So instead you are probably going to favor xv.

that’s another thing I’ve noted… It seems to vanish the config file to mpv, when you list the config folder you can’t see anything:

    ~  ls /home/neji/.config/mpv                                    INT ✘ 
    ~ 
24

Huh? How is it vanishing?
The commands above were for a single run, not for permanent application.
Or are you saying you did have a config file there and it disappears?

As the second thing is rather unlikely, I will assume for now that you simply need the file.
All you need to do is create it, with your desired options.
Example:

printf 'vo=xv' >> ~/.config/mpv/mpv.conf
25

Did you create one?
And put something in there?
what?
… which is now no longer there … ?

mpv does a pretty comprehensive info dump in its verbosity mode (-v) as it initializes and plays. try it with you other switches to get more info when it breaks.
