Mpv failed to start

Describe the bug

I used nix-shell to install mpv and try to start it but this error occurs - "Segmentation fault".

Just small advice, don't screenshot text from terminal. You should copy the text form terminal and paste it here so it could be searched by other.

[Guanran928]

I think you might need to use something like https://github.com/nix-community/nixGL for some graphical stuff to work on non-NixOS distributions.

[Shobhit0109]

Thanks!! for the solution.
This works for me :)

[Shobhit0109]

Reopening this issue because there is no sound when opening with nixGLIntel.
Using pipewire on ubuntu

[eclairevoyant]

nixgl isn't a supported solution and doesn't work a lot of the time; in general graphical apps from nixpkgs tend to work only on nixos

[Atemu]

What's the error message of pipewire?

[Shobhit0109]

Problem: No audio in the mpv using nix flakes.

command: nix shell nixpkgs#mpv --command mpv "https://www.youtube.com/watch?v=scuyV9czoy0&list=RDscuyV9czoy0

That's just the opengl error that requires nixGL to work around.

Please provide the pipewire error when nixGL is in use.

[Shobhit0109]

Using nixGL with intel card. I got a blue screen & mp audio in mpv and these logs.
I am not sure how to get pipewire logs.

Yeah I'm sorry but opengl on non-NixOS Linux is simply not supported in Nixpkgs at this time.

If you have a problem purely with pipewire on non-NixOS Linux we could perhaps look into that because that should work but OpenGL will not work until at least #31189 is solved and it's a hard problem.
