How do I download FFmpeg build for windows 7 64 bit? (Zeranoe’s are offline.) There are two windows build on ffmpeg.org

gyan.dev
BtbN

The first one can’t be downloaded securely.
The second one has lots of files. Which files should I download?
The msg for gyan.dev downloads is a false alarm. All files are delivered via HTTPS. Select Keep instead of Discard.
Chrome shows the same message for Google Earth downloads as well.
This is apparently an initiative by Google to ultimately prevent mixed content downloads in Chrome.
