result of pbMoma on guitar.mp4 is an unplayable 128 byte avi file

I was excited to try this script out, but the result indicates that something has gone wrong.

Here's the console output:

Hi,

you're just having an issue with your OpenCV installation not being compiled with ffmpeg support so it's not creating the video properly. Given your directory structure, I see that you're a Mac user. I was also surprised that brew does not install it with ffmpeg support by default. Just do a "brew install opencv --with-ffmpeg" after making sure to have ffmpeg and you should fix your problem.

The warnings you c/p-ed are irrelevant to your problem.

Hope this helps - feel free to close this issue as it's not related to the code in this repository.

Hi Mr v-v

I may have the same problem without 'a non-integer number instead of an integer will result in an error in the future' problem, It just like 8kb out file problem.

My opencv version is 2.4.8, and I had try to "brew install opencv --with-ffmpeg" , the problem is :

Loo:~ Loo$ brew install opencv --with-ffmpeg

Error: No available formula with the name "opencv" ==> Searching for similarly named formulae... Error: No similarly named formulae found. ==> Searching taps... These formulae were found in taps: homebrew/science/opencv homebrew/science/opencv3
To install one of them, run (for example): brew install homebrew/science/opencv

Loo:~ Loo$

What should I do ?

Thank you~

You probably have to tap into it before, as brew is suggesting: "brew tap homebrew/science".
