Multi-Source Video Capture Cards for Unix?
An anonymous reader asks: "I'm curious as to what video capture cards are being used successfully by the linux user base. I need to capture screen shots from 4 video sources and collect the images in a manner that makes them easy to present in a web browser. A 4 input card would be nice! But I could always use a matrix switcher to grab frames from each source periodically. Matrix-Vision has a card - the mvDelta - that seems to work, but alas, they don't sell single units. What's out there? Who's using it? Any suggestions?"
As an aside does anyone know of a multi-channel TV card?
I would like to record two channels at the same time.
Tivos and digital receivers don't do this which is a real shame.

MJPEG card from linuxlabs i think. awesome hardware MJPEG processor on board and we're using it with 8 channel capture (8 cards in standard PCI slots). comes with linux drivers and a commercial linux editing suite. capturing 8 channels uses almost no CPU time thanks to the hardware video processor.
Our RAID array does the rest by using its on board i960 CPU to dump the data/do the RAID5 stuff (ICP Vortex with 256MB cache).
our CPU runs 80% idle capturing 8 channels of compressed video at full res, 24bits (its a p-3 800). dedicated processors rock.
Use this - it runs Linux, has four imputs and works.

Moneyed corporations, non-working 'poor' and criminal prisoners are turning productive citizens into tax-slaves.
the mvSIGMA-SQ - by matrox - http://www.matrix-vision.com/eindex.htm - it has 4 independant grabbers on one card.... hmm are you high?
Only 'flamers' flame!
Check out Integral Tech (.com). They support Linux and have some frame grabbers with 8 inputs.
