I would like to ask for update to include newest Quadro drivers. They are required for support of newest FFMPEG version. Newest drivers 472.84 supported by this patch will give following error in FFMPEG when trying to test if unlock was successful:

[h264_nvenc @ 000001f87fa2e740] Driver does not support the required nvenc API version. Required: 12.0 Found: 11.1 [h264_nvenc @ 000001f87fa2e740] The minimum required Nvidia driver for nvenc is 522.25 or newer Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

I can test the patch if someone would be kind enough to create it. Many thanks!
