NVIDIA CUDA VIDEO ENCODER FILTER

Hi everyone,
I use directshow to build a graph include “NVIDIA CUDA Video encoder DirectShow filter”
my graph is very simple
“webcam(YUY2)->CUDA encoder->dump(from directshow sample code)”
this graph will return 0x80004005 while IMediaControl::run().
does I lose something need to config ?

Please give me help.
Thank you.
