undivid
Undistort videos using OpenCV.
This undistorts video using a given set of camera parameters and distortion coefficients. You can get these for your camera using one of these packages:

Dependencies
In order to write out the undistorted video, your version of OpenCV will need to be compiled with ffmpeg support. OpenCV is now included in the excellent opencv-python on which this depends. You should have a working copy after
pip install opencv-python
Fallback
Previously, on OSX the easiest way to do this is with Homebrew. I had already installed ffmpeg and OpenCV so this is the sequence I used which got everything working for me:
brew uninstall opencv
brew uninstall ffmpeg
brew install ffmpeg
brew install opencv --with-ffmpeg
If Python has trouble finding OpenCV after this, you may need to do an un/reinstallation of Python before the rest of the homebrew preparations. This is undeniably a pain, but the good news is that your OpenCV install will be a whole lot more useful afterwards.
