Thanks. I made the requested changes and submitted a new patch.


In this context, I wonder if there is some explanation somewhere about the
differences between the cuvid and nvdec codec implementations.

I understand the ffmpeg side where cuvid is a full codec and nvdec is 
implemented as hwaccel. 

What adds to the confusion is that the hwaccel is called 'cuda'.


What I'm wondering now is what difference all this makes at the side
of the GPU acceleration, doesn't this end up being just the same?
Why do we have that dual implementation?

Thanks again,
