The driver is still not ready however I managed to get it going well
enough to encode h.261 using YUV Packed mode. The driver will be
ready when I managed to get YUV12 Planar working -- that is the
card will deliver a single packed which I will be able to just
passed to the H.261 decoder in vic.

Here is what a YUV Packed Mode double word looks like:

Y2 Cr2 Y1 Cb0 Y0
Y7 Cr4 Y6 Cb2 Y3

Here is what YUV12 Planar looks like:

Y4 Y3 Y2 Y1 Y0
Cb2 Cb0
Cr2 Cr0

The H.261 encoder in vic wants YUV12
