Re: CUDA encoder disabled

I know that NVENC is a replace encoder for CUDA.
I have NVIDIA GTX 570 graphics card with the newest drivers.
I have made some changes in C:\Windows\System32 and C:\Windows\SysWOW64\ by uploading nvcuvenc.dll.
When I try to convert H.264 file into H.264 with using CUDA encoder everything works well and speed is very very good.
But when I try to convert H.264 video into H.265 with using CUDA encoder it gives me error 9 which says:

You may have chosen an video format that is not supported by the selected or active encoder backend or multiplexer.

Please help me how to convert H.264 video into H.265 using CUDA encoder?
