Hi, guys.
I'm trying to set up zoneminder on Ubuntu Server 12.04 64-bit, put all packets from the repositories, and after running zoneminder on the monitor opens a black screen and the system log is a text:

Code: Select all

Unable to create conversion context for rtsp://192.168.200.251:554/play1.sdp	zm_ffmpeg_camera.cpp
I hope anyone encountered such problem, thanks.
P.S. Sorry for my English. :oops:

I did it.

I have D-Link DCS-2103 IP-camera
I changed preferences and it worked.
Enter ipcamera's_address in browser.
Choose "SETUP", then "Audio and Video".
When I use "JPEG" I have "Unable to create conversion context for rtsp://... in Zoneminder's log.
Choosing "H.264" mode solves this problem.
