ONLY TESTED ON OSX!!
For this to work, you first need to install FFMPEG (<v.3.0) via homebrew on OSX:
brew install https://raw.githubusercontent.com/Homebrew/homebrew/b42854ae8085fb60ff72a47021a683373ed97e7b/Library/Formula/ffmpeg.rb
To prevent brew from upgrading FFMPEG to the newest version: brew pin ffmpeg.
Then build opencv:
conda install conda-build
git clone https://github.com/postpop/conda-opencv
cd conda-opencv
conda build conda/
conda install /PATH/TO/OPENCV/PACKAGE.tar.gz
