[FFmpeg-user] nvenc h264 encoding

[tyt xtreme]

Thanks for the help and explanation! I can tell the encoding runs now,
tried with the following command:
$ ffmpeg -i perspective.mp4 -c:v h264_nvenc -profile:v high -preset:v fast
perspective_out.mp4

but the output image/video coloring really weird. from a normal coloring
it's going to be weird mixture of green,red "ghosty" image.
The input file details are:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'perspective.mp4':

Any idea?
