4 port video capture card using the bttv module - use Composite0-3 at once
I am trying to use my own software that I have created in Adobe Flash to work capture cards to create a flash video surveillance system. This means I need the functionality of Linux to interact with these video cards (norm, tuner, composite etc...) instead of using xawtv.
This is my seutup:
Linux kubuntu kernel 2.6
pci 4 port generic video capture card. it has one conexant chip and works with the bttv mod
When I do a dmesg | grep it outputs:
[58.069712] bttv: driver version 0.9.16 loaded
[58.069724] bttv: using 8 buffers with 2080k (520 pages) each for capture

Looking at other peoples setups I see that they have a bttv1, bttv2 etc which I believe represents capture cards or a capture card with multiple chips. In my /dev/ i only have video0, this is because the card I have only has one chip but four ports.
With the bttv mod:
modprobe bttv card=77 pll=1 no_overlay=1
v4lctl norm NTSC
I then open up my flash software and select the card 77 that shows up as a camera option and I have video capture composite0. I can change the composite input with this command
v4lctl setinput composte1
This works great but I still only have one input.
So how can I get all four inputs to work at once?
