Adaptation for mpv's argument parser changes

[nagy]

According to this commit0 mpv now requires an equal sign between the parameters and their arguments.

Hey @dieterdeyke @dbrock do you think this should be merged? mpv player fails to play with Process ‘bongo-mpv’ exited abnormally with code 1 without this change.

cc @iqbalansari since you added mpv as a backend

Actually, I noticed another error popping up in mpv when changing the song, with this change.

Error running timer ‘bongo-mpv-player-tick’: (file-error "make client process failed" "Connection refused" :name "bongo-mpv" :buffer nil :family local :service "/var/folders/f3/j94kxrl177b_fn9gzqkytwgw0000gp/T/bongo-mpv.socket" :filter bongo--mpv-socket-filter) [2 times]

This doesn't seem to be causing any loss in functionality though.

I'm witnessing this same error. How did you solve?

I haven't. They come up a few times and then the song plays automatically.
