;;; Commentary:
;; This provides a player that uses mpv. It supports pause and
;; seeking. See mpv manual for more.
;;
;; To load subtitles automatically,
;; put "`sub-auto=fuzzy"` in the mpv's config file.
;;
;; To disable the cover display when playing music, use the following:
;; (add-to-list 'emms-player-mpv-parameters "--no-audio-display")
;; Alternatively you can also add "audio-display=no" to mpv's config file.
;;
;; This file is based on `emms-player-mplayer.el'. It was originally hosted at
;; https://github.com/dochang/emms-player-mpv.
