[Libav-user] Encode with hardware example

[Shu Wang]

I'm using nvenc to encode h264. If reading frame from host memory, it's
nothing special from libx264.

But there is another problem I'd like to ask help here.
I don't know how to create a hw av_frame directly from device memory.
For example, hw decoding usually output a hw av_frame, which usually
following av_hwframe_transfer_data to copy it back. What if I want to
encoding it in device memory directly?
