Is it possible to directly use the decoded yuv buffers from a CUvideodecoder in OpenGL without the need of an intermediate copy as shown in the AppDecodeGL example?
Good question. From what I see in the NVDEC API, it is not really possible unless nvidia gives us ability to share GL resources for decoder input, as in NVENC
