[FFmpeg-user] ffmpeg NVENC won't run

[Leonardo Pagotto]

Hello everyone,

I've installed Cuda toolkit, Nvidia driver and compiled ffmpeg,
installation went smoothly. all seems to be loaded but trying to run it
starts and stucks, no error messages but won't go any further, even on a
very basic command w/o NVENC. What can be wrong?
