To do that you'd need 3 elements in your pipeline: appsrc !
<yourdecoder ! appsink

Check the documentation for them here:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsrc.html
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsink.html

Appsrc and appsink are elements that provide an API for feeding and
receiving buffers from the pipeline.
