Sorry to have to ask [1], but what are they? Which one do I download if I have an Intel Core 
i7-6700HQ CPU with Intel(R) HD Graphics 530 & NVIDIA GeForce GTX 980M?

[1] There's no guide at https://github.com/BtbN/FFmpeg-Builds/releases. There's no guide at 
https://ffmpeg.org/download.html. And searching for "gpl-shared-vulkan", for example, just produces 
links back to https://github.com/BtbN/FFmpeg-Builds/releases & links to URLs in Chinese. I also read 
the FAQs and Wikis. Maybe I'm just unlucky, eh? Finally, there's the ffmpeg-user archive, but no way 
to search it. Oh dear.

Guidance is much appreciated.
