-------------------------------------------------+--------------------------
 my ffmpeg seems to segfault when converting the .nuv files from my frame
 grabber to flv
 using this small patch(which depends on mencoder) ive worked arround the
 problem
 it needs a fifo at /tmp/mythwebflash right now to work(forgoten too much
 perl to make it automaticaly)
 basicaly mencoder just writes raw video/pcm audio to the fifo and ffmpeg
 converts that to flv
