Since this segfault might involve the v4l2 input format, I am interested
in the bugreport. Can you provide a backtrace, as indicated at
http://ffmpeg.mplayerhq.hu/bugreports.html ?

Also, I just committed a more strict check on some parameters returned
by the v4l2 driver... Can you do a "svn update" and repeat the test?


			Thanks,
				Luca
