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

Far from me to defend the whole mpv team[1], but the dev in that thread is a ghost (deleted user). I remember them, they were always rude and eventually got kicked out of the project and loudly complained about “being removed from the project [they] created”. I never found the exact reason why, though I can’t help but think the attitude had something to do with it.

[1] Some are quite nice and competent. Others are exceedingly rude and will e.g. jump on an issue that had thus far been entirely cordial just to, without provocation, insult users for using whatever OS they don’t like.

The last issue that caused them to leave was their desire to move mpv to their own build system, which they believed they could write in a weekend. Other mpv developers thought that was a stupid idea and argued in favor of something more standard, such as meson. That was the last straw for both sides.
