Installing opencv-3.1.0 on MacOS Sierra to use with python

I recently upgraded to MacOS Sierra and I have been dealing with many issues (I am mentioning it cause it may be relevant). I am trying to install opencv-3.1.0 to use with python 2.7. and it's been impossible. I downloaded opencv-3.1.0 from here unzipped it and ran:

python platforms/osx/build_framework.py osx

from the opencv-3.1.0 directory. Don't want to print all of the output, so here is just the Error message. 

** BUILD FAILED **


The following build commands failed:
    CompileC osx/build/x86_64-MacOSX/modules/world/OpenCV.build/Release/opencv_world.build/Objects-normal/x86_64/cap_qtkit.o modules/videoio/src/cap_qtkit.mm normal x86_64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler

Would appreciate your help. Thanks.

After following the post here I was able to install it just fine by running:
brew install opencv3 --HEAD --with-contrib

The issue appears to be related with the QuickTime codecs. You need to specify that the library is installed with ffmpeg instead and it should work.

brew install opencv3 --with-ffmpeg --with-tbb --with-contrib
