I'm having an issue with setting up monitors on a ZM (1.24.2) install on my Seagate Dockstar using Debian Stretch. The camera I'm using is a Logitech C120, it's UVC and plays nice right out of the box with debian. I've used it with mjpg-streamer without any problems.

When I go to setup a monitor and go to probe I get an error:

Unable to probe local cameras, status is '137'

Which I've searched for and can't find *any* mentioning of it.

So I try to manually call zmu with Which just returns "Killed". I'm using the root account over ssh. Trying sudo I get nothing returned.

I cannot change to the source tab under the monitor settings. I also cannot delete the test monitor I created (it's setup looking for a /dev/video which doesn't exist so I get an error in the logs because of it).

When I run/restart zoneminder it always reports starting up fine, same with apache, mysql and php5...so...I dunno.

I'm guessing it's all just a permissions issue but I'm not savvy enough with linux to intuitively know how to fix it. Any thoughts?

Anyone?

I'm not sure entirely what you do, so this is quite woolly. The mention of /dev/video says it's a local camera mounted by linux, but mjpeg-streamer confuses it.

I don't use probe so can't advise there.

If it is local, find out where it is mounted in /dev/ (may be /dev/video1 video0 etc) and change that in the source.

If you're using mjpeg-streamer, is that accessible via http? Or are you saving as jpgs locally?

If former, you'll need to setup the camera as 'remote' and http://localhost/filename for the source.

If latter, use file (but ime, this way ends up with tears and half pictures as zm tries to read a file still being written)

The camera is at /dev/video0. It's a Logitech C120 and it uses the standard UVC driver (bought it for just that reason).

My use of mjpg-streamer was just to test the local camera (it's a headless system, no video card what-so-ever). Didn't mean to be confusing there. I don't have mjpg-streamer running at all tying up the camera when I try and access it from ZoneMinder. Zoneminder just seems unable to check for cameras.

The only error codes I found online were '255' and '137' which typically involve network cameras-- not local ones (like mine is). Error 127 just doesn't seem to exist in any documentation/forum posts.

I've run a C120 on a head-less armel as well. You are sure you can view the feed? To test mine, I used VLC to pipe /dev/video0 to a feed I could view from another machine.

I had issues accessing the device directly with ZM as well (diff. than yours), so I setup VLC to stream /dev/video0 locally, and used ZM with the FFMPEG option to connect to it, and it worked fine. Not much diff. in load either. Maybe try a roundabout-ish way like that.

Hmm. I'll try that. I can view an MJPG stream remotely using mjpg-streamer so I know the camera is setup fine as far as kmods go. Maybe I'll pipe that in to zoneminder.
