There is now a cython based wrapper for ffmpeg (https://github.com/mikeboers/PyAV) which allows API access to the underlying library. The project seems to be stabilizing and there are now conda recipes for both linux and OSX, wheels for OSX, and reports of it building on windows.

We should add a movie writer based on shoving images

See scikit-image/scikit-image#1012 for general discussion of movies and https://github.com/soft-matter/pims/blob/master/pims/display.py#L21 for an example of how to use pyav to write out a movie.
