This is a Heroku buildpack for Python apps, powered by pip. The only difference from the clean Python buildpack is that this one includes ffmpeg. A static build is simply cloned from this repo, which includes a couple of useful codecs (see the ffmpeg output below), but still trying to be light on disk space.
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-ffmpeg.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-ffmpeg.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.
You can also provide arbitrary releases Python with a runtime.txt file.
$ cat runtime.txt
python-3.3.2
Runtime options include:
- python-2.7.4
- python-3.3.2
- pypy-1.9 (experimental)
