Mpv – A free, open-source, and cross-platform media player

This is an extremely venerable project, formerly known as mplayer. There are half a million commits going back to 2001, and that’s just from when the CVS repo was converted to Subversion.

streamlink and mpv on a fanless Minix z100 running Ubuntu was a nigh-on perfect Olympics experience.

I don't think mplayer and mpv are the same thing. It forked mplayer (among others), but mplayer is still its own thing.

I switch from mplayer to mpv some years ago but I don't remember when. I use it daily as my media center player.
