[Cin] Testing Nvidia Nvenc encoding

Fri Dec 27 20:54:54 CET 2024

Andrew, are you saying that nv-codec-headers at 10.0.26.0 in the current
CinGG work with your GT710? and that the newest 12.2.72.0 does not?  If so,
then maybe we should not upgrade.  When I look at the support matrix (url
below) it does not mention the GT710.

https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new
BUT when I do a compare of the old one we have currently and the latest at
this website:
       https://github.com/FFmpeg/nv-codec-headers/releases/tag/n12.2.72.0
I get the following differences which DO NOT say anything about dropping
support for any previous Nvidia graphics boards.
Below list the comparison which shows what was changed from the older
version to the latest
