(You provided complete, uncut console output for the 
working command line and severely cut output for the 
failing command line, it should really be the other 
way round.)

I unfortunately cannot test h264 over v4l2, I tested 
the following command line (raw video) and it works 
fine, so I don't know why it fails for you:

$ ffmpeg -f v4l2 -i /dev/video1 -vcodec copy out.nut
out.nut plays fine with MPlayer and ffplay.
