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.
This is a static build of ffmpeg:
./configure --enable-static \
--disable-shared \
--disable-asm \
--enable-libtheora \
--enable-libvorbis \
--extra-libs=-static \
--extra-cflags=--static \
--prefix=/app/vendor/ffmpeg
To use this buildpack, you should prepare .buildpacks file that contains this buildpack url and your real buildpack url.
$ cat .buildpacks
https://github.com/HYPERHYPER/heroku-buildpack-ffmpeg.git
https://github.com/heroku/heroku-buildpack-ruby.git
The first build pack is the git URL to this repo. The second build pack is for a Rails app, see https://github.com/heroku for other app build packs.
$ heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git
$ git push heroku master
...
You can verify installing ffmpeg by following command.
$ heroku run "ffmpeg -version"
