 I have Easycap DC60 card(a video capture card). it runs on kernel 3.2 with
 stk1160 driver. I download ffmpeg source code on 3013/03/29 and compile
 it.
 when I run a commandline:

 [root at localhost ~]# ffmpeg -f video4linux2 -pix_fmt yuv420p -i /dev/video0
 -vco                                                      dec mpeg4 -b:v
