[Live-devel] Streaming NVENC H.264 through testH264VideoStreamer.cpp

[Philippe Noël]

After further work, I have found that NVENC returns NAL units and so I will
need to write my own FramedSource. I'm very new to all of this and have no
idea how to do so, is there specific examples of working with NVENC I could
find somewhere?

Cheers,

Philippe
