Maybe my question is not correct. If both encode H.265 but I thought the
performance ability (to create compression ratio) should be the same or at
That means CUDA version is only for some purposes and traditional open
libx265 version for others? I guess, the CUDA is only for streaming, but
then the decrease size of frames ( so increased compression ratio) to
Harald, could you elaborate about those because I am really excited to know
about it. Maybe I have compiled something wrong. I've been looking at it
from yesterday so maybe I missed something in documentation :)
