I have an auto-updated tap for the ffmpeg binaries from https://www.osxexperts.net, feel free to

  brew tap bsiegel/tap

I got frustrated having to install all of the runtime dependencies and just wanted an easy way to install the statically-linked version, so here it is.

6.1.1 is the latest build from the 6.1 release channel, which was the latest up until about 4 or 5 hours ago when a new major release was cut.

Not at all the same as running a 4.x release.
