does It provides a zero memory copy interface between GStreamer and OPENGL on TK1?

I want to use opengl to process the data that from GStreamer decoded and then get new EGLImage , finally encode and record the EGLImage by GStreamer , is it support a zero memory copy between EGLImage and GStreamer data ?
the data does not have to be copied to cpu memory. and Improve performance.

Please share your current gstreamer pipeline so that we can give suggestion.
