I have developed a program in opencv python on linux and now I am trying to run it on mac.

But now I am getting the following error on running it. I installed opencv using brew.

I finally solved the problem myself, for some reason the fullscreen mode does not work on mac, disabling that solved the problem for me.

  • Fullscreen mode does work on mac ... but not always! I have a program that works fine on a raspberry Pi, but aborts with trap 6 when trying to enter fullscreen mode after os.system call to mplayer on Mac .... but only the second time through the same section of code (for a second event)! The start up of the program enters full screen mode fine. The first event happens, program exits full screen mode, launches mplayer (in full screen mode), then re-enter full screen mode after mplayer exits. Second event happens, program exits full screen, launches mplayer again in full screen mode, then trap 6 – Ian Ellis Feb 17 '16 at 23:56
