Can you try to compile the following short C program
int dummy = V4L2_PIX_FMT_YUV420;
struct v4l2_buffer dummy1;
with "gcc -c <progname.c>" and tell me the error you get?
Also, send me (in private mail) the /usr/include/linux/videodev.h and videodev2.h headers.

Uhmm... This looks like a driver problem. I do not know what it means, but maybe you can ask on the video4linux mailing list. I've never seen it.

I do not know about the --cpu option, and I suspect the gcc version is not important.

I think that if the version that you are trying have a consistent avcodec.h/avformat.h interface you can simply change ffmpeg.c.
Anyway, I hope to be able to find why v4l2 is not detected in a short time... That would fix your problem, I hope.
