PV-155 / Ubuntu 9.10 only seeing channel /dev/video0 0

[davinman]

So I have just installed the latest version of Zoneminder on a brand new Ubuntu server build. The card I am using is a 16 port PV-155 purchased from Bluecherry. I used the guide located at http://www.zoneminder.com/wiki/index.ph ... ver_32-bit and all seemed okay when I hooked up the first camera to /dev/video0 0 but when I hooked up the next one and created the monitor it would not activate. It seems that creating a file bttv.conf in the modprobe.d directory with option card=77,77,77,77 and a reboot fixed the issue. I can create monitors on all 16 channels but they all have blue screens except video 0 0 (tried moving several cameras around to make sure the ports were numbered correctly).

I searched some more and found that I should uncheck V4L_MULTI_BUFFER which I did with no change. I built ZM with --enable-mmap to avoid any shared memory problems and I see that data is being written to /dev/shm fo ZM.

I am at a loss so here are some output of what the server sees for the card.

Hi there,

Thanks for posting the topic hopefully we can solve this.

I have recently installed ubuntu 9.10 server also, x64 version with 4x 500GB HDDs in RAID format. 80GB OS drive.
It also has a PV capture card 16port in it. I am unsure of the exact model number.

Currently I have 8 video channels loaded in dmesg
bttv0 to bttv7, all linked to vbi0 to vbi7 accordingly
Output can be shown as: (bttv7 shown)

I couldn't get anything to work originally with zoneminder. What I had to do was add /etc/modprobe.d/bttv.conf with the following:
options bttv card=98,98,98,98,98,98,98,98
Once added, restart the box and it showed vbi0 to vbi7 succesfully.

In zoneminder I'm able to get video0 but the rest of the channels show blue. It also has another 8 ports which don't seem to show at all.

Hope someone can point us in the right direction

Attached a pictures of my capture card. It has techwell markings on it. Could someone help me identify it? With Card=98 it seems to detect and /dev/video0 works succesfully /dev/vbi0.

Here are some pics of the card/box/adapters

[davinman]

I think that I have figured this out. I have 3 cameras currently on

/dev/video0 0
/dev/video0 1
/dev/video1 0

I have the modprobe.d set to option bttv card=77,77,77,77 and I have set CAPTURES_PER_FRAME = 2 and turned off V4L_MULTI_BUFFER in the config. The other part that I was missing was the permission in Ubuntu on the video devices. I forgot that they change after each reboot so instead of trying to change them or the udev rules I placed the apache user in the video group. Once I did that I can see all three cameras.

Thanks,
David Inman

Hi there,

The card in the picture is not a PV card.

[adamu]

What is it?

Could you give me the cardnumber to be put in modprobe?
So far I've only succesfully got output with using card=98. PV150.

adamu First off you will get more help if you post your own thread.
anyway. if you get a blue image your on the right track.

I assume you have 4 capture chips based off the 4 techwell chips I see.

It may be that you need to set a device channel aka which port. its in the camera setup window. This is because the card will switch back and forth between the cameras to capture the images. Probbly 1-4 per /dev/video

and most likely if i am right about the 4 capture chips
card = 98,98,98,98

May be you can fix the /dev/videox in /etc/udev/rules.d/83duplicate.rules Like this you can conf one to one cam and fix the problem
