I’m running Fedora Linux 28 on a i7-5960x with 1080TI GPU. I installed shotcut from flatpak and it is running just fine. However, when I click “Use hardware encoder”, I always get “Nothing Found”. If I force h264_nvenc, which I believe is supported in the 1080TI, the final export is a black blank video (although, I can hear the audio). I’m using nvidia driver 410.78 with Linux kernel 4.19.10-200.fc28.x86_64.
What do I need to do to enable hardware encoders?
