This repository is for my own personal use. You may use it, however it is not guarenteed that it will continue to be hosted at the same git url or download distibution url. I strongly suggest you either use the original, or clone your own version.
Run the following from the heroku command line:
heroku buildpacks:add --index 1 https://github.com/hmh84/heroku-buildpack-ffmpeg-latest.git
Note: This buildpack should be added before the main language buildpack (by using --index 1),
since the application process types are calculated from the last buildpack in the list if no
Procfile is specified.
