Heroku buildpack: FFMpeg

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.

Usage

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/shunjikonishi/heroku-buildpack-ffmpeg
https://github.com/heroku/heroku-buildpack-play

$ 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"

Building the Binary

The ffmpeg binary was built using the ffmpeg-static build scripts on a heroku stack-image VM.

To build it yourself

• clone the stack-image heroku repository to your local machine via git clone https://github.com/stvs/ffmpeg-static, then cd into it
• run vagrant up
• run vagrant ssh
• now clone the ffmpeg-static repo into the virtual machine: git clone https://github.com/stvs/ffmpeg-static
• cd ffmpeg-static
• ./build-ubuntu.sh

if the final ffmpeg compilation step fails due to a missing library (such as libopus):

• manually copy the ffmpeg ./configure command, remove the --enable-opus line, and then run it again
• run make manually

I had to disable libopus and one other library if I remember correctly.
