This is a Heroku buildpack for Python apps. The only difference from the clean Python buildpack is that this one includes a static build of ffmpeg 2.1 with codecs. The static build is simply cloned from this repo.
It uses virtualenv and pip.
Example usage:
$ ls
gunicorn.py.ini Procfile requirements.txt wsgi.py
$ git init
Initialized empty Git repository in /path/to/app/.git/
$ heroku create --stack cedar --buildpack git://github.com/integricho/heroku-buildpack-python-ffmpeg2.1-with-codecs.git

You can also add it to upcoming builds of an existing application:
$ heroku config:add BUILDPACK_URL=git://github.com/integricho/heroku-buildpack-python-ffmpeg2.1-with-codecs.git
The buildpack will detect your app as Python if it has the file requirements.txt
in the root.
It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with --buildpack <your-github-url>
and push to it.
To change the vendored virtualenv, unpack the desired version to the src/
folder, and update the virtualenv() function in bin/compile
to prepend the virtualenv module directory to the path. The virtualenv release vendors its own versions of pip and setuptools.
$ cat runtime.txt
