Im setup using rtp/udp. What i have been able to figure out so far is that i can set a ip address, and it will stream the video to that address. I am not sure how to setup ffmpeg or anyother program to 'listen' on a socket, so i setup the stream as a multicast. In wireshark i can see UDP data pacakets from the encoder.

Now i understand to open a RTP stream i must have access to a URL that contains a SDP file, which describes the datastream. Apparently the the manufacter (verint) will not release the SDP.

Any ideas anyone on how i can get video out of this unit?! As far as i can tell the video is in a standard format, I just dont know how to tell ffmpeg how to decode it without the SDP.

Perhaps this would be better for a ffmpeg list, but i though i would post here first as this device is specificialy manufactured to be a survaillence video encoder.

OK for a new device you bets bet is to make it public and alow us to look for a path iwith wireshark (or you can).

what do you need to be put online? the encoder? or the zone minder? there is no web interface on the controller only telnet. either way will not help you unless you come to my house.

We I assumed the encoder unit had a web interface which every unit i have used so far has. But from what you said it dosent
