Why do i get error of when i m trying to read a video file

 ??? The file requires the following codec(s) to be installed on your system:
 video/mpeg
 Error in ==> VideoReader.VideoReader>VideoReader.init at 423
             obj.VideoReaderImpl = audiovideo.mmreader(fullName);
 Error in ==> VideoReader.VideoReader>VideoReader.VideoReader at 133
             obj.init(fileName);

You do not have a codec for video/mpeg installed on your system.

Which operating system are you using? And are you using MATLAB in 32 bit or 64 bit mode?
