Where is NVCUVENC?

Hi, I’m using CUDA 6.0 and NVCUVENC (Nvidia H.264 H/W Encoder DirectShow Filter)
CLSID is {B63E31D0-87B5-477f-B224-4A35B6BECED6}
but, when I update CUDA 6.5 and Graphic Driver 340.52 latest, I can’t use NVCUVENC anymore.

I want to official information about Nvidia Driver has CUDA 6.5 what version.
and, any other Nvidia H.264 H/W Encoder DirectShow Filter? (not NVCUVENC)

NVCUVENC is going away. If you look at the CUDA 6.5 release notes and other entries on this forum, you will find descriptions of this.

Thank you.
I found CUDA 6.5 release notes.
