Hi Lou,

Here it is uncut:
---
omap3-multi:~$ sudo ffmpeg -loglevel debug -v verbose -f libdc1394 -i
hw:0,0 -vcodec mpeg4 -b:v 10000k -bufsize 150000k -r 640x480

[libdc1394 @ 0x1cdc520] Can't find matching camera format for uyvy422,
320x240 at 29970:1000fps
hw:0,0: Operation not permitted

However, I can still get the same output by just doing `ffmpeg -f libdc1394
-i hw:0,0`

Thanks,
Bryan
