I have a nice H264 decoder based on this one:
And I would like to use the h264 CUVID decoder instead, and receive the
frames as Nvidia objects. I know there is some kind of callback that
allows me to get some kind of CUptr that has the decoded I420 frame in
I'd like to feed my OpenGL renderer the data directly, without
downloading it to RAM. I have some experience with Cuvid, I just don't
know how to get the Nvidia handle for the decoded frame, or how to setup
the CUVID decoder from the API.
I think VDPAU is meant to do this, but I'm on Windows.
