Bt 878/Generic difficulties

Hi all,

ZoneMinder 1.23.3

First time trying to set up zoneminder and I'm having some difficulties with a bt878 card.

The actual card (I think) is an Adlink Angelo RTV-24 (identified by the picture on bttv gallery)

I have tried everything I can think of. The camera works (plugged it into a TV) the card driver SEEMS to load but all I ever get is a blue screen in xawtv.

I've played around with modprobe options and xawtv settings, etc. but am at my wits end.

the output from lspci -v looks like this:

02:00.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
Subsystem: Unknown device 32da:c84e
Flags: bus master, medium devsel, latency 64, IRQ 11

I'm a little worried about the Subsystem:Unknown.

dmesg looks like tthis:

I see the bt878 module trying to load and failing. I've tried removing the module from the kernel and am not really sure what the difference is between bt878 and bttv.

Anyways - I'm about to give up on this card but thought someone here might have some insight.

thanks for any help!!

According to the bttv gallery, there is a binary only driver presumably provided by the manufacturer for an older kernel version and no apparent driver included in the bttv kernel module working.
For the moment it appears it's not yet supported in the linux kernel.

Thanks,

i was wondering about that but I assumed that it was an old post. I guess i'm out of luck on this card then?

I have the PCI Express version of the card (PCIe-RTV24) and all I had to do was add this to the /etc/modprobe.conf file (I'm using centOS 5.2 and ZM 1.23.3. Only tested with one card with one cam for one day in monitor mode)

alias char-major-81 bttv
options bttv card=134,134,134,134
options bttv tuner=0,0,0,0
options bttv autoload=0,0,0,0
options bttv radio=0,0,0,0

This is the thread I got it from. I did not install the manufacturer's driver as none of them matched my kernel version. (2.6.18)
