Error registering an input resource: resource register failed (23)Could not register an input HW frame
Hi,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 frameThe 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._______________________________________________
