Custom opencv filter can't use GPU, please help!

#include <stdio.h>
__global__ void myk(void)
{
printf("Hello from thread %d block %d\n", threadIdx.x, blockIdx.x);
}
extern "C"
void entry(void)
{
myk<<<1,10>>>();
printf("CUDA status: %d\n", cudaDeviceSynchronize());
}
#include <stdio.h>
void entry(void);
int main(void)
{
while(1) {
entry();
}
}
I call this in opencv filter as below:
...
extern "C" {
void entry(void);
}
....
void myopencvfilterOpenCVImpl::process (cv::Mat &mat) {
entry();
}
Please help to answer how can I make GPU involve when I call it in kurento filter, thanks a lot!

Thanks, today I understood problem it is the GStreamer problem. I could call gpu method with right functionality but I should now get around the gstreamer.
