Sorry,
didn't see your original email..
seems we are working on the EXACT same thing. I had noted the EXACT problem
you have, and am working on a solution. If you are interested, I have the
maximum frame rates achievable without syncing the cameras....
1 camera / 25 total
2 cameras/ 16.67 total
3 cameras/ 10 total
4 cameras/ 7.07 total
These are rough numbers with a simple model of the video signal, and the
actual sync requirements of the card ignored. However, I have tried it with
the associated number of cameras, and noted that if I go above 16,10,7 I get
the chopped frames, so I'm pretty close ;-)
I would be interested in seeing the work you have done on opening four video
streams to capture to. I am working with vcr by Bram, and will be changing
to 4 AVIs today. I have very limited processor to work on (C3 800), so it
will be interesting.
With regards to the VSYNC, I am investigating video buffers (some aren't
that expensive..), and will let you know how I go.
Stay in touch!
Miles
