OpenCV crash when attempting to capture default iSight camera

Question

I am trying to get openCV running on my Macbook Pro (10.8.5, retina model), and I want to use the default iSight camera for input, as I don\'t want to carry around or buy a USB

Answer 1

The problem was with the version of openCV used (2.4.6). For access to the iSight camera, you have to use 2.4.5, until whatever bug was introduced in 2.4.6 is fixed. To get 2.4.5 on OSX from Homebrew:

$ brew versions opencv
$ cd /usr/local/Library/Taps/homebrew-science

checkout git version to older version:

$ git checkout ae74fe9 opencv.rb

remove the original version of opencv (probably 2.4.6)

$ brew unlink opencv

install 2.4.5 version:

$ brew install opencv
