[Libav-user] How do I access and use Nvdia Encoder functions?

[Joel Ng]

I know that, but I want to try to use the Nvidia functions through 
FFmpeg because I already have a fully working code written using FFmpeg 
functions. I will need to learn the whole Nvidia SDK if I use their SDK.

Do I have no choice? I cannot use FFmpeg to do this?

Thank you.
