A simple boilerplate Flask application with support for ffmpeg and numpy. This example uses the (somewhat old) python-ffmpeg-buildpack. Future support should use .vendor_urls and multibuildpack to reference the most up to date heroku-python-buildpack.

To deploy this application after cloned, simply:

$ heroku create --buildpack git://github.com/integricho/heroku-buildpack-python-ffmpeg.git
$ heroku config:add BUILDPACK_URL=git://github.com/integricho/heroku-buildpack-python-ffmpeg.git

You may also want to use gunicorn with gevent, in which case simply edit the Procfile and requirements.txt to add the dependencies and declare the web process.

To use it locally, you must download pip and virtualenv

$ sudo easy_install pip
$ sudo pip install virtualenv

Optionally, install foreman and heroku Ruby Gems

$ sudo gem install foreman heroku

Now, you can setup an isolated environment with virtualenv.

$ virtualenv --no-site-packages env
$ source env/bin/activate

On ubuntu, install the necessary packages: $sudo apt-get install python-dev

Next, install the requirements in your isolated python environment.

$ pip install -r requirements.txt

Now, you can run the application locally.

$ python run.py

You can also run it using the production server if you install libevent-dev and foreman, but I am leaving that for another day, it also is difficult in Windows

$ foreman start
