Hi, I am trying to use ffmpeg to encode, following the steps on:

> **[NVIDIA FFmpeg Transcoding Guide | NVIDIA Technical Blog](https://developer.nvidia.com/blog/nvidia-ffmpeg-transcoding-guide/)**
>
> All NVIDIA GPUs starting with the Kepler generation support fully-accelerated hardware video encoding, and all GPUs starting with Fermi generation support fully-accelerated hardware video decoding.

I got ffmpeg build, however when I want to encode a video with it shows the following error:

> #ffmpeg -i input.avi -c:v h264\_nvenc output.mp4  
> …  
> [swscaler @ 0x55d34678d0] deprecated pixel format used, make sure you did set range correctly

It seems CUDA SDK is up to date:

Is there a older version of ffmpeg that supports h264\_nvenc ?  
Or how do I check or update the nvidia drivers ?
