So tonight I moved over my 4-port CCTV board from my Win2k system to my FC3 system running ZM 1.22. It picked up the card fine on the first try, and I didn't need to tweak anything significant yet. I had to increase shared memory, which is of course all over these boards and the FAQ.

Here's my new issue...I couldn't find anything in the forums that matches this problem...

When I switch a camera from 320x200 to 640x480, I get a 320x200 image TWICE, side-by-side, rather than a hires single image. The board is capable of higher. Here is the output from zmu:

If I'm reading that correctly, it should do 768x480. Why am I just getting 2 side-by-side copies of the same picture, rather than a single hires one? Is there a setting somewhere to override the board to get hires?

Thanks in advance for any input....

My first thought is that the card was not correctly detected.
Try running:
dmesg |grep bttv

Looks like there was some kind of error on detection:

Running Fedora Core 3. Even with the error, the 848 series card runs fine in any res (though I couldn't use my PAL camera on it, only NTSC ones). The 878 card is a quad-input capture card (single chip). Neither of the cards have a tuner on them (BNC input only).

So I am trying to force the card type as "77", as seems to be common on the forums in hardware issues. When I do, I now get the 848 picked up as an 878, and the 878 is still UNKNOWN:

Do I need to specify the card type in the modprobe somehow? Here's the output from lspci and lsmod:

Any help would be appreciated....this seems like it's "close" to being totally up now.

you nbeed to restart zm after a res change but ideally you need to set up your card better.

Can you please be more specific on "setting up my card better"?

After adding the option line to modprobe.conf, it is picking up by 848 input card as an 878, and my 878 is being still done as auto-detect and comes up in an error state.

The options for modprobe.conf are listed above in this thread. Further options to give this would be appreciated. Since both use the same bttv driver, how do I specify module options for each card separately? I'm assuming now that my video problems are due to the driver not being picked up correctly for the 878.

Cheers...

options bttv card=0,77

This is assuming that the card is really 77. We don't know what cards you really have so this may or maynot work.

Likely it's not type 77. My lspci shows:

00:06.0 Multimedia video controller: Brooktree Corporation Bt848 Video Capture (rev 12)
00:07.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

I can find lots of info on the bttv driver on bytesex.org, but nothing that lists the card types. Do you happen to have a listing of the card types? Getting the right one of these will likely cure many of my problems...

Cheers.

Card types are listed in the kernel documentation.

For online reference, in case anyone needs it, the card types are listed here:

http://tldp.org/HOWTO/BTTV/cards.html

So for my problem, my 848 card looks to be an early Hauppauge. That was somewhat easy. My other card has ZERO manufacturer info on it. But I found one that resembles it on EBay here:

http://cgi.ebay.com/NEW-4-Channel-Video ... dZViewItem

If anyone could help me identify this card, it would be of great value...the docs for it merely list it as "UCC4", which has nothing even close in the card list. It is for sure an 878 chipset on it, though.

Cheers.

thats a card 77 mate

That card on ebay is a card 77.

just... lol

James, I'm not sure what is so funny....I don't think I've personally ever laughed at somebody on a forum when they needed help. Not everyone is an expert...

Cordel, I highly appreciate the help you have given me with this over the past week. Your insight has been helpful many times. Thank you very much.

whoa there mate
you will see that i said and corey said about card 77, i beat him 'just' but less than 60 seconds
i was not laughing at you in anyway
