Hello,

I was attempting to extract some metadata of a couple of videos using MediaInfo CLI and MediaInfo gem (http://github.com/greatseth/mediainfo). However, when attempting to access the duration of a video I get the following possible bug notification:

Abort trap


Here's the invoking code:
          begin
            debugger

            info = Mediainfo.new destination_file_path
            
            return false unless info && info.video? && info.video.count == 1
            
            self.duration = info.video.duration
            self.fps = info.video.fps
            
            true
          rescue
            logger.fatal "Unable to access Video Info through MediaInfo CLI!\n$!"
            return false
          end
