As a gstreamer newbie I started writing a small python/gstreamer app about a year ago. Fetching a snapshot out of a running videostream took me months. I almost abandoned gstreamer altogether because of this. This feat, currently, requires an unproportionally huge knowledge of gstreamer inner workings to accomplish. I also see this question appear from time to time on the mailing list. Therefore, in all humbleness, I suggest to the gstream core developers to incorporate into gstreamer a snapshot element that hides this mess from a regular programmer.
