ZoneMinder Forums

Hey everyone.

I'm running zoneminder 1.24.0 and I have a bluecherry ProVideo PV-150 (bt878). The drivers load correctly according to Dmesg. I have 4 cctv cams and in zoneminder, I can get /dev/video3, /dev/video2, and /dev/video1 (all on channel 1). It works beautifully, each cam is running incredibly smoothly.

However, I cannot get the /dev/video0 to work properly with *any* setting. This includes PAL/NTSC, smaller resolutions, color changes, and channel changes. As I remember, /dev/videoX with this particular card is only accessible on chans 0-3 anyway. All I get is a big fat blue screen. The logs tell me that /dev/video0 is capturing at 30fps. Nothing weird in the logs. I know that the camera is working because I can swap the coax cable with one that is attached to another video and it comes up just fine.

Here is what I've tried thus far:
modprobe'd with card=77,77,77,77 and 134,134,134,134 and 98. By default it loads the 98. nothing seems to change with any of these options.

I thought it might be a permissions issue so I've changed it to 777 on /dev/video0 to no avail.

I've increased by Shmmax and Shmall (as I had a small shared memory issue a while back, but now that is gone)

I've tried physically re-arranging the ports attached to the card.

XAWTV reports all video(x) as OK and using v4l2. My kernel doesn't seem to be listed on the "non compatible" bug list. also, XAWTV picks up everything except for video0, so I know it's not a zoneminder specific problem.

zmc reports video0 with the same settings as al the others.

I am in need of some major brainstorming here. Any ideas will be greatly appreciated!!!!

Oh and one last thing.

I contacted BlueCherry and they mentioned something about switching to Video4linux 1. Is this even possible and if so is it a viable idea?

Did you install Zoneminder 1.24.1? If so its an option further up the page where you set the resolution in settings...

I don't quite understand what you mean by that. The resolution can be set in all versions of zm.

After you click on the create the monitor for /dev/video0, the Capture Method under the Source tab can be set to Video for Linux version 2 OR 1 - you can pick either.

Interesting. I don't seem to have this particular option. I'm guessing that's not included with 1.24.0, just 1.24.1 and above?

So. Any other ideas from anyone who might have had this issue?

Strongly suggest updating to 1.24.2, allot has been fixed since the 1.24.0 release.

I imagine you've tried moving the ports around, but in my limited analog experience, blue screen means it's successfully capturing that channel, you just don't have anything plugged into it.
