FreeBSD ffmpeg with h264 acceleration via NVENC/NVDEC

Hi all,

is anyone aware if it's possible to build ffmpeg with support for Nvidia's NVENC/NVDEC? It doesn't appear on the configure options, nor does libav or CUDA.
I *think* the API is made available in x11/nvidia-driver.

Thanks,
Scott
 
Thanks drhowarddrfine. Do you know if multimedia/libav will allow me to do H264 decoding and encoding in hardware with ffmpeg? It may not actually help my issue but I'd like to find out. I have a few RTSP camera streams coming in which I'm rebroadcasting via multicast (as well as saving segments to disk). That works well but when I overlay the camera name and current time then the CPU usage goes up.

I got here through a search engine.
I was able to do hardware encoding on 13.4 as well, so I will leave a note.
