Hi all,
I am having a custom PowerPC board running eldk-5.3 with xorg.
When i try to grab video using the following command i get the following
error.
However i was able to grab video with Xvfb and x11vnc on the same board and
same ffmpeg library.
What parameter i  messed up with?
Anyone has a clue?

-r 30 -i :0.0 -qscale 0.1 -t 3 grab.avi
