The planar support seems to be broken, giving green output and hanging
the chip.  The easiest test case is using gstreamer (I highly recommend
this for anyone doing video stuff).

Reference video:
gst-launch-0.10 videotestsrc ! video/x-raw-yuv ! ffmpegcolorspace ! ximagesink

YUYV video (works):
gst-launch-0.10 videotestsrc ! ffmpegcolorspace ! video/x-raw-yuv,format='(fourcc)'YUY2 ! xvimagesink

I420 video (fails):
gst-launch-0.10 videotestsrc ! ffmpegcolorspace ! video/x-raw-yuv,format='(fourcc)'I420 ! xvimagesink
