No streaming - ZMU doesn't detect cams
Posted: Wed Sep 01, 2010 10:22 am
Hello I'm back after 3 years (my precedent post was in 2007)
I'm now under ubuntu 10.04 (lucid lynx) and I try to install a new config on a netbook with Zoneminder 1.24.
Install without problem but its impossible to see any stream with these 3 : internet UVC Webcam, external analogic cam (wich worked fine in my old config) and external creative webcam.
Lines monitors are always red and when I open I've blank screens.
I tried to use remote option with UVC cam and mjpg_streamer as indicate on wiki : no result.
I also tried zmfix.
All these cams are working with xawtv and other viewers.
Thanks very much for your help, here is the result of commands :
