Thanks, but I'd like to store the resulting video in ogg format. How
do I put the frame buffers into a pipeline again to encode the video.


Basically you're saying the way to do this is having 2 different
pipelines where I copy buffers from one to the other myself.
Isn't there a gstreamer element that can switch the streams seamlessly.
