[Cin] Testing Nvidia Nvenc encoding

[Phyllis Smith]

Andrew, I am having difficulty interpreting the statement "min driver
note".  According to:

https://forums.developer.nvidia.com/t/h264-nvenc-the-minimum-required-nvidia-driver-for-nvenc-is-520-56-06-or-newer/233144

the minimum nvidia driver is 520-56-06.

Is that what you mean should be included in the release notes?
