This is a Heroku buildpack for using ffmpeg in your project.
It doesn't do anything else, so to actually compile your app you should use heroku-buildpack-multi to combine it with a real buildpack.
# Ruby buildpack
$ cat .buildpacks
https://github.com/issueapp/heroku-buildpack-ffmpeg
https://github.com/heroku/heroku-buildpack-ruby
# for new project
$ heroku create --buildpack https://github.com/ddollar/heroku-buildpack-multi
# for existing project
$ heroku buildpacks:set https://github.com/ddollar/heroku-buildpack-multi
$ heroku config:set FFMPEG_BIN_URL="http://johnvansickle.com/ffmpeg/releases/ffmpeg-release-64bit-static.tar.xz"
$ git push heroku master
# verify and profit!
$ heroku run "ffmpeg -version"
