I'm having some problems getting this script worked out. I still don't have
'faac' support, 'mplayer compiled without libmp3lame support, and
'x264encopts is not an MEncoder option'.
What syntax do you use?
./script.sh input.file ?? ?? output.file
Sorry - I've been trying, but am still away off getting encoding working!!
Thanks
