Video encoding with nx_vpu

Pawel
Hi.

I am trying to encode video using hardware accelerated chip. I have manage
to open device and set it up, however i cannot find out how to push frame
to encoder.

I am using nx_video_api.h from:
https://github.com/friendlyarm/nexell_linux_platform

Is there any sample code about hardware encoding from raw stream?

Best Regards,
PAweł
