Hi.

I'm setting up a Zoneminder system with a MDVA3000 capture card.
THe card is recognised by the bttv kernel module as UNKNOWN/GENERIC (card=0,autodetected) card, gpio: en=00000000, out=00000000 in=001fffff, but in Zoneminder I see a black & white and quite disturbed images.
The cameras ar colour, of course.

This is a screenshot of the image I get from the cameras:

This is the output of the bttv module when it is loading:

Code: Select all

What's the problem?

Thank you very much for your help!
Bye.

I also have this same issue with Black and White images only. My Cameras are PAL and i have the zoneminder source set to auto as this is the only way it works. I tested by also connecting an NTSC camera and i see that the image is now in colour so can only assume that the system drivers for the BT878 Card are set to NTSC. How can i set the Video card to PAL settings as once tgis is done i think that the camera will now operate in PAL and colour. Would appreciate details on how to configure BT878 driver to default to PAL system.

you need to tell your system what card you have so the driver can talk to it correctly. While the geniric driver will work sometimes, it rarly works 100%

I found the answer and added these lines into modprobe.conf as i am running fedora.

#bttv
alias char-major-81 bttv
options bttv card=77

now my camera's work in colour - so my issue is resolved. I will try differant card numbers to see if i get a better performance.
