gst-launch output

Hello

I am using a v4l device whose driver does not advertise I420; however,
requesting I420 does "work" (but the picture is of course corrupted)

GST_DEBUG=v4l2*:5 gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 !
"video/x-raw, format=(string)I420, width=(int)1920, height=(int)1080,
framerate=(fraction)30" ! fakesink -v

Output is attached.
