Hi,
I don't feel like I'm really near to solving this. The best I can say is

Hi,
theoretically this should do it:
gst-inspect-0.10 v4l2src ! video/x-h264 ! ffdec_h264 ! autovideosink
but, if i'm correct, current kernel do not support h264. There was a

Hi Tomas,
all listed error come directly from usb driver. uvcvideo driver do not
even have chance to talk with your cam. It should be some hardware
issue. Try to check the cable.
