Driver does not support the required nvenc API version. Required: 9.1 Found: 9.0
[h264_nvenc @ 0x560d30a9b6c0] The minimum required Nvidia driver for
nvenc is 435.21 or newer
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

I have installed:
NVIDIA-Linux-x86_64-430.50.run and cuda_10.1.243_418.87.00_linux.run
