This is a Heroku buildpack for ffmpeg.tar.gz - x264, mp3lame, libvorbis, libogg
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.
To use this buildpack, you should prepare .buildpacks file that contains this buildpack url and your real buildpack url.
$ ls .buildpacks ... $ cat .buildpacks https://github.com/brooks/heroku-buildpack-ffmpeg-x264 https://github.com/heroku/heroku-buildpack-ruby $ heroku create --buildpack https://github.com/ddollar/heroku-buildpack-multi $ git push heroku master ...
You can verify installing ffmpeg by following command.
$ heroku run "ffmpeg -version"
Copy the snippet above into CLI.
