Error in cudaDecodeGL

Developer Tools CUDA Developer Tools CUDA-MEMCHECK

When I run cuda-memcheck for the CUDA sample cudaDecodeGL, it reported the following errors.
Can we solved the errors in API?

Best Regards,

Hi William NG. Thank you for reporting this. Currently, cuda-memcheck does not support applications that perform CUDA + Direct3D interop.

Also, can you try running the cudaDecodeGL application outside of cuda-memcheck ? Does it succeed ?
