A couple of weeks ago I installed stremio from the AUR on my arch installation and it showed me an option to play the video in mpv player.

I expected the same thing on my NixOS setup but it doesn’t show me the option to open in MPV. I also tried with flatpaks and it also didn’t have the option to open in mpv.

As for why I want to open on MPV, I am using anime4k to upscale and sharpen my anime and I’m very used to mpv’s controls.

Does anyone know how to get this working ?
