I have a gstreamer pipeline that uses this element:
nvivafilter cuda-process=true customer-lib-name="libnvsample_cudaprocess.so"
I have some things that I need doing once for the lifetime of the filter. To my dismay, I discovered that pre_process and post_process are called for EVERY frame, and not just once for the lifetime of the filter. gpu_process is also called once for every frame.
So what is the point of pre_process() and post_process() functions as they can already be wrapped up in gpu_process?
