D-Link DCS-930L

Thank you. That seems to have work. It only runs for a limited time. How can
I set it to record for 5 minutes. How many buffers do I need ?

The following worked for me and VLC was able to play it back:

gst-launch souphttpsrc location=http://guest:@96.57.244.98/videostream.cgi
num-buffers=1000 ! multipartdemux ! jpegdec ! videorate !
video/x-raw-yuv,framerate=10/1 ! ffmpegcolorspace ! x264enc ! flvmux !
filesink location=dcs.flv

Hope it makes sense.

Try user guest and no password. The ip address is fine.

When I try it, the provided URL isn’t valid. From what I can tell, it should
be: http://96.57.244.98/videostream.cgi

However, the provided username/password (admin/Supp0rt1) don’t seem to work
and the camera is blocking streaming video. Perhaps you could setup the
camera to stream anonymously? It’s hard to help if you can’t access the
stream and see what’s going on. If that’s a problem, dump the video stream
to a file and then attach it (if it’s tiny) or provide a public url where it
can be accessed.

Any help would be appreciated.

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:

Content-length: 45536

etc..

I have loaded gstreamer on to FreeBSD and I am looking to collect the video
from a video camera,
DCS-930L (D-Link) for example, and save it to a file that I would like to
play it back using an internet browser.
I am mostly interested in collecting and saving the file to a standard video
format (.FLV if possible)

Being new to gstreamer I am looking for some guidance as to how to start
and/or a sample program to start from.
I am an experienced programmer in C and C++ but a novice to gstreamer.
