logitech c525 works in mjpg streamer but not in zm?
Posted: Sat Dec 03, 2011 7:49 pm
Ok...I have a really old, pentium3 733mhz computer and am trying to run one usb webcam (logitech c525) with zoneminder.
I can view the (remote...not local) stream using localhost on port 8080 and action equals "stream" just fine (NOTE: putting this in link form was tripping the spam filter).
The camera also works in gvpcview and cheese, etc.
However, when I try to view the stream in zoneminder it's all black.
I should note that the text for "monitor" (under the 'function' heading) is yellow and the text for "localhost" (under the 'source' heading) is red.
I'm willing to bet that that means something isn't playing nicely here.
Is this a shared memory issue? I did some searching and probably went overboard by doing this;
I should note that this awesome computer tops out at 512 MB of RAM (which is what I have in it).
I was under the assumption that running one lousy webcam shouldn't be too much to ask with this configuration though.
I'd think that using 'local' as opposed to 'remote' would be better but I haven't figured out what those settings might be.
Thanks for any advice.
