коллеги пытаюсь заюзать для видео кодирования данную видеокарту ( GeForce GTX 1080 дрова NVIDIA-SMI 440.64.00 Driver Version: 440.64.00 CUDA Version: 10.2 ) но почему то выдает ошибку
[h264_nvenc @ 0x556a2263f340] hw_frames_ctx must be set when using GPU frames as input
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
