You can pass "-autorotate 0" to stop FFmpeg from trying to rotate the video (which it cannot perform if you use a full cuvid pipeline), but of course if thats required, it might still be a problem.

Now it works perfectly with your advise.
$ ffmpeg -hide_banner -hwaccel cuvid -c:v h264_cuvid -resize 854x480 -autorotate 0 -i waterfall.mp4 -c:a aac -c:v h264_nvenc -rc vbr output.mp4
Replying to heleppkes:

The rotation of input file is the problem. But i dont know how to fix it.
Does anyone know how to solve it?
