Hi Dwaine,
thank you for testing the driver and thank you for the link. But I'm
sorry, that the input values didn't match with your device. Now let's
fix the Problem. Can you please tell me some details of your camera:
What is the exact name of your device?
Is there an saa7111a chip in your device?
Wednesday I will try to use a NTSC video source with my HAUPPAUGE
device. The signal will come from a pattern generator, but I hope it
will match your TV norm.

Yes. The maximum now is 320x240 to prevent overrunning of the
nt1003-FIFO. Maybe you can use a bigger
size when changing the value of BUF_THR (reg 0x30) on nt1003. It is set
in usbvision__set_compress_params.
I hadn't yet time to test it.

Maybe the video mode bits on the saa7111a isn't set right. I did some
changes in usbvision_muxsel to have correct S-Video input on my
WINTV-USB FM. There you will find a line:
int mode[] = {0, 1, 7}; //modes of saa7111 fix me (this is only for
Hauppauge WinTV)
Prior the 7 was a 2. If a 2 gives colored pictures to you, than we must
add an device depending if-clause.

I can see the picture on your site.
I think the value[2]=0x20 and value[3]=0x01 (number of videolines) in
usbvision_set_input are wrong.
Try value[2]=0xF2 and value[3]=0x00 or similar. Then you have to shift
in horizontal direction by changing
value[4] and value[5]. Maybe changing 0x51 to 0x60 is ok.
