Comment (by Ilya87):

 @philipl, Oh, yes - another bug found (ffmpeg for Windows x86_64),
 ffmpeg.exe -hwaccel cuda -hwaccel_output_format cuda -i D:\sample.mkv -c:v
 h264_nvenc -b:v 5000k test.mp4
 Leads to
 [h264_nvenc @ 000001f2d7a86b40] Driver does not support the required nvenc
 API version. Required: 9.0 Found: 8.1
 [h264_nvenc @ 000001f2d7a86b40] The minimum required Nvidia driver for
 nvenc is 390.77 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

 While my driver is 417.01. Error mesage is deprecated.
