If someone knows about this ioctl to set/read gpio pins directly, could
you please post it? I have a PC/104+ bt878 card (it's called a Sensoray
311) that has some of the gpio pins just routed to a header for doing
generic digital io (which could be used for camera triggering, for
example). It would be fun to try it out.
As for the 16-camera multiplexer, it may be easy to figure it out if you
can find out which chip the mux is, and how it's connected to the bt848.
It seems to me that the way they'd do it would be to switch 4 lines at
a time, since the 848 has a 4-way mux internal to it.

I saw a post some time ago about a hack who use the audio ioctl's to set
these pins.
Sorry, couldn't find them...

Subject: Unsupported card (remotevision mx)
Hi folks,
I just got a pci card from a security system of up to 16 cameras
package. Unfortunately this card is not supported on bttv driver and i
couldn't find any reference on it's specs or linux efforts for it. It
seems that it's a kind of rare, because nobody knows it.
The card is called rv606, or RemoteVision MX, from a company called
privid eye. The home page is http://www.privid-eye.com/mx.html
It uses a bt848 (rev 12) and has some other auxiliary ICs. Doesn't
support sound, but multiplex 16 inputs.
I'm wiling to spend some time trying to make this card work (i got no
image using the programs like gspy) and provide support for it on bttv
driver. I'm C programmer with some experience on kernel hacking.
Could anybody provide me some starting points? What should i look for to
make it work? As it uses a bt484 how much can it differ from the other
already supported cards? as i said, sound is not a issue.
Thanks,
