Thanks for these instruction! However, how can I adjust these command to install this inside a conda environment and create bindings to the python version from the conda environment?

Will this support ffmpeg. If I would like to have ffmpeg support, what should I modify in your instructions. Planning to install it on a python 3.6 virtual environment (linux mint 18.1).
