install.FFmpeg: Downloads and installs FFmpeg for windows
Description
Allows the user to downloads the latest version of FFmpeg for Windows.
IMPORTANT NOTE: The user (YOU) are responsible for unpacking the 7zip file into the relevant directory. All that this function does is to download the 7zip file and "run" it.
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec - the leading audio/video codec library. See the documentation for a complete feature list and the Changelog for recent changes.
This function downloads current releases and NOT the Development Snapshots.
This function is useful for saveVideo() in the animation package.
