Jason,
Glad it is going OK. Note that xawtv would view one channel at full frame rate and this is why there is smooth appearance there. What is the maximum fps setting for your channels in ZM as it should be capable of going above 4 fps with this card.
Please post the output for one channel from your dmesg as well.
Regards,
Conor

conor,
I can get 25 fps but the motion is jerky, especially when viewed in slow motion. It's more puzzling than annoying. Here's the dmesg output.
thanks,
J

hi just to reserect this one
I have what looks like a 4400r and adding
options bttv gbuffers=16 card=133,132,133,133
makes it work great as a 4 hannel card but when i then add dev/video1 channels 0-3 they are just a copy of whats connected to video0.
Does anyone know how to get all 16 channels working in zm. They all work in tvtime but are called composite0-15 (well all but 6)

Hi James,
Here is something I had posted a while back.
http://www.zoneminder.com/forums/viewto ... ht=kodicom
This board does not work like the rest.
You have inputs 0 to 15,
by tieing an input to a device (/dev/video0 (3) ) you are telling the board to put that input on that device
The mux chip is responcible for doing this.
So unlike the other cards where the input is constantly tied to the bt878 chip, this one is not.
Regards,
Corey

yes corey thanks. I have another card on eof those tibet cs16 (card=131 i think) and that works like that /dev/video0-16 but on this kodicom once i go above video3 video4 goes red. I can get 6 ports to work slowly by using video0 and channels 0-5 but 6 and abive dont work. I have tried it in 3 different boards now (via,intel and nvidia chipsets) all with the same result. I hoped a kernel update would do it but i have gone upto 2.6.14 and still its the same lol. (i was hoping one of my saa philips cards would work too but alas. Maybe i have a faulty kodicom, but it seems ok as long as you only use the 4 ports on th card itself

I just bought the exact same card off ebay... Why does it take 30 minutes for me to run:
Code: Select all
modprobe bttv gbuffers=16 radio=-1 card=102,102,102,102,102,102,102,102
lspci shows:
Code: Select all
02:08.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
02:08.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
... 7 more times
when modprobe finally does finish, and after eating 90% of my cpu... i run tvtime and get a red screen with some lines with snow...
confused, help.
thanks

James,
If you have the card that I think you have (4 bt878s) the setting 133,132,133,133 is for a 4 chip card so you would only have video 0 to 3.
stealth,
Apparently you have your card setup up wrong and need to open your own thread so we can work on your issue effectivly unless you know that you have a kodicom 4400 card

Thats ehat i have nbeen using mate and i can get all 16 (well apaer from 6) working in tv time. In tvtime they are listed as composite0 -15. But this wont work in zm and i can take it up to 6 channels then no more

I am sure I have the same card pictured. as for the slowness I looked at the tvtime site and they said with bttv try to play with i2c and use
which worked.. all 8 chips probe in under a few seconds.. but now in tvtime all I get is horrible lines.. I can see that it is taking input and there is some motion but its really bad. when i remove the input the screen is red.

Ah, my bad.. it was Xgl that I just began playing with. It seems tvtime and Xgl do not play well together just yet. I switched back to normal Xorg and the first input runs well.
