[FFmpeg-user] Compiling ffmpeg with NVENC and NVIDIA GRID K1

Hello,

I compiled ffmpeg with nvenc support. The compile process worked without any error. But if I try to convert a file with nvenc I got the error message "[nvenc @ 0x39dc1c0] CreateInputBuffer failed".

Can somebody help me to fix this problem?

Best Regards
