I am currently looking to read a frame (from a video), directly with the GPU using a Jetson Xavier.
The board is on Ubuntu 18.04 and Cuda 10.2
I already managed to read a video and upload each frame on the GPU with OpenCV C++, but now I would like to directly decode the frame using the GPU.
From what I understood I can’t directly read a frame with OpenCV (on GPU) because we need NvCuvid which is not available for Jetson Xavier.
So I know that VPI, VisionWorks and GStream are installed on my board. How can I use and which should I use to read a frame without using CPU.
Is there some code example in C++ ?
Thanks for your time and consideration.
