Capturing a random frame from a webcam using GStreamer in Python

I am trying to write a program for controlling a robot by interpreting frames from a webcam and occurred in GStreamer.

I was able to cast video in Python from a webcam using GStreamer using this page: http://www.ndeschildre.net/2008/04/04/python-power/

However, I do not know how to request a single RGB-encoded frame from Pipeline, and although I managed to find and read part of the documentation, I did not find the obvious answer.

Does anyone have any ideas?

EDIT: I tried using OpenCV first to solve this problem, but the buffer does not stay in place or something else, and causes the sequential images to not start in the upper left corner of the buffer. (Ubuntu Linux operating system)
