Problem of NVENC sdk sample on GTX690

leicester · May 16, 2013, 2:08am

Hi
I am trying to test the NVENC sample on GTX690.
I encounter a error message as below when run the sample program.
File: src\CNVEncoder.cpp, Line: 1380, nvEncOpenEncodeSessionEx() returned with e
rror 21
Note: GUID key may be invalid or incorrect. Recommend to upgrade your drivers a
nd obtain a new key

Does anyone know how to obtain the GUID key to use NVENC sdk?

Thank you.

I’m getting the same error on a GTX680 on a Linux Ubuntu desktop and no getting any support response. Please let me know if you got the problem resolved.
