But one thing that confused me seeing that homepage is that it shows a player UI screenshot, but it says " mpv is a free (as in freedom) media player for the command line", isn't just for the command line right? I assume you can install it as an app and it has an UI like VLC. (I'm on the phone rn will check it on my PC later).
% mpv file.mp4
That's what they mean.It doesn't really have things such as "File → Open" like VLC has. At least not out of the box, but it's scriptable with Lua and there are scripts and even entire "alternative frontends" that can do this.
It can also be remote controlled via a socket; I built an audio player like this; works pretty well.
In general, if you want a "Windows-like" or "macOS-like" experience then VLC is pretty good. If you want a more "unix-beardy" experience then mpv is pretty good.
Sure the possibility to tweak the UI is limitless, but at least there are minimum usable UI, like gvim (Windows, Linux) or macvim (macOS) which are easy to install.
Huh, it does for me (in the menu bar) on macOS! I guess that's platform-specific then?
If you set it as your default video player it will work as you expect.
If you don't want to set it as your default video player you can probably do something like "Right Click -> Open with..." and choose MPV.
