I am planning to add CUDA compilation support in LibAV with a CUDA sample. The 
challenge here is that NVCC Cuda Compiler supports GCC compiler under Linux and 
MSVC compiler on Windows. So GCC compilation under Windows becomes an issue.

The Clang compiler is still in infancy stage and doesn't support the latest SDK 
and architectures.

I am planning to have the CUDA files compiled for the Linux/GCC and 
Windows/MSVC (MingW) platforms, and for Windows/GCC (MingW) we can store the 
PTX files that have been generated on Linux or Windows using MSVC compiler.

We can improve this on a later date once we have more support on MinGW/GCC 
either through nvcc or Clang. Let me know if there are more ideas to explore.

Thanks,
Yogender
