I am unable to locate the CUDA Video Decoder GL API sample in the 5.0 installation.
My install (on ubuntu linux) seems to have almost all other samples.
The decoder sample must be under the /samples/3_Imaging folder. Additionally, I could not locate the CUDA Video Encode (C Library) API sample and the CUDA Video Decoder D3D9 API sample.
I have not been able to verify if these samples are missing from the windows installation as well.
