rtsp/sdp as source

Hi,
I've searched the web and forum without success: is it possible to use a rtsp/sdp server as "remote camera"?
The reason is that i have a lan camera which is accessible in 3 ways: rtsp, jpeg and an activex control.
I can run mplayer on the rtsp access (it used ffmpeg) and i have 24fps.
I can use ZoneMinder with the jpeg image but then i get only 1 fps.
So i'm looking for a way to use the rtsp server as ZoneMinder monitor.
Michael.

Currently this is not possible. However it is something I am looking into. I _think_ that ffmpeg can capture from rtsp sources but I have not got it to work reliably yet. If I can get ffmpeg to do it, then I should be able to apply the same thing to ZM.

Thank you for your reply. I'm very sure that ffmpeg can capture rtsp because i simply can run "mplayer rtsp://cam1/live.sdp" to view the cam's output.
Here's the mplayer output when i do this. maybe it helps a bit:

Phil would it be possible to use something like
http://www.live555.com/openRTSP/
to convert the feed for you. It looks like it is doing what you need but I'm not sure if it is the right format.
I just got in some Grandstream GXV-3000 Video phones at the office that support rtsp video streaming and it would be a cool feature to add.
Let me know if I can do anything to help.

Hi there,
I've got the exact same issue. I have an IP camera that uses MJPEG for its streaming, but using the RTSP protocol and not plain HTTP. I was just wondering if there's been any progress on this in ZM?
Thanks in advance,
Ramin
