Can't get shared memory

wonderfulll · Post by **wonderfulll** » Tue Mar 24, 2009 4:00 pm

Hi,
I installed ZM on Ubuntu 8.10 machine from this http://www.zoneminder.com/wiki/index.ph ... ozola-0.7) tutorial.
Everything seems to work just fine.

Now i want add a remote internet camera D-Link DCS-2102.
Remote protocol: RTSP
Remote method: RTSP/RTP
Remote host name: 192.168.1.124
Remote Host Port: 554
Remote Host Path: /jpeg (also tried mp4)

After adding I get no image.

zmwatch.log

Check you don't have two versions of ffmpeg installed, ie one from your distro and one you may have compiled yourself.

ffmpeg can't recognise rtsp source.
Maybe camera output is just not supported by ffmpeg?

One other thing to check is that your don't have a firewall running on your ZM box that is preventing your cam from connecting back into ZM.

That is the nature of RTP etc in that you tell your cam what ports to connect back to ZM on and then the cam send the stream back via UDP. If you have a firewall on then you need to make sure that the range in Options->Network (I think) is permitted through or your's cams IP address is.

This last bit here is zms the stream server in ZM, I believe you wanted to look at zmc the capture process.

did full reinstall of the system (Windows 7 host, VirtualBox guest with host interface), without previous mistakes, but still getting the same error as in the beginning
