Ffmpeg HW-Acceleration issue on Jetson nano

When compile ffmpeg HW-Acceleration on Jetson nano, there is error reported as below.

[h264_cuvid @ 0x55a5fcb460] Cannot load libnvcuvid.so.1
[h264_cuvid @ 0x55a5fcb460] Failed loading nvcuvid.

How can I realize ffmpeg HW-Acceleration on Jeston GPU? Thanks!
