Carlos, You men you want to store the data that you captured from the webcam ? you may even like to refer to <a href="http://github.com/Elleo/gst-opencv">http://github.com/Elleo/gst-opencv</a> project incase you intend to use gstreamer and opencv ? best kapil <div class="gmail_quote">On Fri, Apr 9, 2010 at 2:00 PM, Carlos Castro <<a href="mailto:carloscastro7@gmail.com">carloscastro7@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi everyone, I'm trying to get a snapshot from a webcam that is continuously sending the picture to a GTK+ app using a gtreamer pipeline, so I can save that snapshot as a IPLImage, to later use it with OpenCV. I searched the web to find the answer and I found that I could use a gstbuffer to store the frame that gstreamer grabs from the v4l2src, but I couldn't get it to work... How do I get the data from the pipeline to the buffer?
