Hello,
the attached patch adds support for mpv (http://mpv.io)
It is mostly copy-paste from emms-player-mplayer.el and
emms-player-simple.el
The main difference from mplayer is that mpv has local socket IPC
instead of stdin slave mode. Therefore the code generates a temporary
socket file for each player invocation, and carefully tries to remove
that file after player exits. A simpler version could use a fixed
socket file, maybe via defcustom, but then concurrent mpv processes
would get mixed up. I am not sure if that rather theoretical risk
warrants the complexity, though.
regards,
Petteri
