[Libav-user] Internal error: Could not register an input HW frame

I am writing an h264 encoder, and the video frame data is from Nvidia GPU.
If the video frame was transferred from GPU memory to system memory, the encoder worked fine.
But I want to encode the HW frame directly to avoid performance loss. When I called avcodec_send_frame, I got an error :
Error registering an input resource: resource register failed (23)
Could not register an input HW frame
The error was triggered by nvEncRegisterResource function.
I'd like to know what I should do if I want to use HW frame directly, expecially on how to set AVHWFramesContext.
Is there any example about this? Now, I just referred to vaapi_encode.c (https://www.ffmpeg.org/doxygen/4.0/vaapi_encode_8c-example.html).
Thanks for your help.
