If one compiles mplayer with USE="-png" and runs it via
"mplayer -vf-add screenshot"
as smplayer does in _default_ configuration, then mplayer will crash.
There should be either a built check
if ! built_with_use media-video/mplayer png; then
die "Smplayer needs mplayer to be built with png support, to prevent crashes."
fi
Maybe ewarn instead of die is sufficient. If ewarn is used, there should be a
comment, that one can clear the "Folder for storing screenshots" field to
prevent smplayer from adding -vf-add screenshot to the command line it passes
to mplayer.
