No skins for the gui version but as long as gtk+2 is available they can easily be added. However if I do use mplayer in xorg I just use the same commandline as I do on the 'linux' terminal except with the '-vo xv' or '-vo x11' or ... switch on an xterm commandline. Also all this can be scripted out in bash to make it more powerful of an app. For example I have a bash script with a 'scan' line (<- requires ffmpeg) that determines the size of a fullscreen output on the 'linux' terminal;

aspect_ratio=$(ffprobe -v error -select_streams v:0 -show_entries stream=display_aspect_ratio -of csv=s=x:p=0 $1)
if [ "$aspect_ratio" == "4:3" ]
then
Resolution=1440
else
Resolution=1920
fi

$1 in the above is the movie to be played. The resolutions in this case needs to be adjusted for whatever the maximum resolutions are for the machine's display. It works great for '-vo fbdev2' on the 'linux' terminal commandline for a widescreen monitor.

As you've said; Touch the right key at the right time and the instrument will play itself. Yes indeed.

Life is good,
Maurice

... Don't cry for me I have vi.
