VLC Cuda support possibility for recording or encoding h264

Hello,
The interrest of NVIDIA CUDA technology which use GPU (parllel tread) instead of CPU (single tread) for encoding HD video (h264) has been clearly established.
Why not integrating possibility to use CUDA in VLC encoding?
I think this new feature is much more than needed (ffmpeg seems to have understood that)
So it is a dream i want to be true.
Thanks,

CUDA is not integrated in FFmpeg, and I doubt x264 will integrate a vendor-specific code.

why cant vlc enable CUDA in the player and not have to waite for FFmpeg or x264 to do somthing

CUDA isn't some flag you can just turn on compile time. You have rewrite decoders if you want to use CUDA in them. And it isn't trivial task.

Personally I would wait for OpenCL because it works on all GPU and OSes. CUDA is mostly NVIDIA only.

There are a few time-consuming algorithms like DCT that could probably be moved into a library that can use different backens. Not all parts of coding/decoding are better dune in the GPU... Such a library could support CUDA, OpenCL and various other hardware platforms. On Playstation 3 one may prefer to have a library optimized for CELL.
