ZoneMinder Forums

I'm working on getting ZoneMinder up & running on an old netbook (EEE900HA). It has a Rosewell WebCam connected. The OS is Ubuntu Server 12.04 LTS (32-bit).

I've got it all installed and can access the webpage. I've got Camobolza installed as well.

I am, however, not getting feed when I try to view the camera. The error "Failed to get picture attributes: Invalid argument" is the most interesting thing to appear in the log as far as I can tell.

A screenshot of the system log, a screenshot of the attributes of the attached webcams (I believe /dev/video0 is the internal webcam and /dev/video1 is the external USB webcam. I am attempting to use the external USB webcam), and a screenshot of the camera settings (I've tried a few variations with no luck) are attached.

I've searched the web & wiki for my error message and have found next to nothing about it.

If anyone has any insight on how to fix this I'd appreciate it.

Thanks,
Sean

Video for linux version 2 doesn't work either?

I can't say it "doesn't work" but I haven't gotten it to work yet.

When I said I had tried a variety of settings that included using Video For Linux Version 2. I was unable to tell what some of the settings should be from looking at the output of zmu -q. For instance, Device Format & Device Channel. I switched over to Video For Linux Version 1 because it had AUTO as an option for Device Format.

As far as i know, uvc webcams require video4linux version 2. Can't help you though except if nothing else works, you could try mjpg streamer work-around? And oh, if i remember correctly uvc webcams use yuv format

Thanks for the leads.

I'm new to all this. Can define a few terms?

"UVC" Webcams?

MJPG Streamer Work-Around? Do you have a link?

I agree with it looking like YUV422 is correct for the Palette (based on the output from zmu -q). However, I still don't know what the "Device Format" is supposed to be. This NTSC, PAL, etc.

Thanks,
Sean

UVC = USB Video Class, some kind of generic format for communication for webcams etc.

The program can be found here:

Device format could be mentioned in the webcam documentation?

Thanks for the links. I'll read through those.

I checked Newegg, Amazon, the Manufacturer's Page, & the User Manual... No mention of the format in any of those places.

I'm also going to try to this webcam on a Desktop Installation of Ubuntu with Cheese before I work too much harder to get it running with Zoneminder on my Ubuntu Server machine.
