Thanks Johannes.
I tried a straight:
svn update && svn revert . && aclocal && autoconf && ./configure && make
same issue.
I've attached the webcam lsusb -v info, maybe the 901 has a different camera?
I'm linking with libv4l-0 0.5.7-1~intrepid1
Let me know if you have any ideas, otherwise I'll leave this off the demo
list.
Thanks all.
