I actually have this camera and was playing with it and gstreamer last week.
I hope what I am about to mention is not way over your head and helps give
you a pointer as to where to start with this camera. As for starting with
gstreamer, just keep reading through the mailing list and the docs on the
main site

First thing is to narrow down the source of the video. I have yet to find an
accessible audio stream but have not put to much time into looking. The
video I found are

http://user:pass@192.168.1.15/image/jpeg.cgi
http://user:pass@192.168.1.15/video/mjpg.cgi

replace user,pass and the ip with yours.

the mjpg stream is what you are going to want to look at. Also the elements
souphttpsrc, (most likely)multipartdemux,jpegdec and flvmux.

My problem has been that multipartdemux refuses to work because "Boundary
not found in the multipart header" . I have looked at the stream and the
boundary is:

--video boundary--

but specifying it still does not work which is where I was getting hung up.

This pipeline does not work but just as a rough example

gst-launch souphttpsrc
location=http://user:pass@192.168.1.15/video/mjpg.cgi! multipartdemux
! jpegdec ! flvmux ! filesink location=dcs.flv

Again, this pipeline does not work but I believe it to be a step in the
right direction.



For those that may be able to help with the multipartdemux issue wget of the
mjpg.cgi shows the following and this pipeline always fails with " Boundary
not found in the multipart header"

gst-launch souphttpsrc location=http://admin:@192.168.1.15/video/mjpg.cgi !
multipartdemux boundary="--video boundary--" ! jpegdec ! fakesink


wget http://user:pass@192.168.1.15/video/mjpg.cgi mjpg.cgi contents:

etc..
