When I run: /etc/mplayer/mplayer.conf
The system returns:
bash: /etc/mplayer/mplayer.conf:Permission denied
mplayer.conf is a configuration file. It cannot be ran. If you want to edit it you must use an editor like vi, gedit, or whatever editor you're using. For example run
and change/add the options you want.
Note that if you want mplayer to support large files (>2B) you need to compile it with the "--enable-largefiles" option.
