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

I use it to inspect video frames by frames, particularly being able to go back one frame. VLC doesn't support it, this thread about the feature is hilarious https://forum.videolan.org/viewtopic.php?t=120627

I was hoping that mpv would work a bit better than vlc for sending video to chromecast, but unfortunately, another similarly amusing thread: https://github.com/mpv-player/mpv/issues/177

It's a former developer that's no longer affiliated with the project since 2021 or thereabouts. They did not part on good terms because he behaved in the same way towards other mpv developers, "my way or the highway".

So you probably shouldn't let anything that old sour your opinion on the current mpv.

(I don't belong to either side, just have been using the player since its inception.)
