NVENC Geforce GTX 680 licensing

Hi,

Is there any extra license key required to set NVENC acceleration up? I faced the error below when was trying to use NVIDIA Geforce GTX 680.

"File: nvenc/src/CNVEncoder.cpp, Line: 1424, nvEncOpenEncodeSessionEx() returned with error 21

Note: GUID key may be invalid or incorrect. Recommend to upgrade your drivers and obtain a new key

NVENC error at nvenc/src/CNVEncoder.cpp:1426 code=21(NVENC Feature not available for current license key type) “nvStatus”

"

Hi,

We have had this question before about the Geforce GTX 680 and NVENC.

According to official nVidia sources, this video card does not support NVENC.

There appears to be some incorrect information online that suggests that the card does support it.

Roger.
