When you are using videoFReader function, AudioOutputPort property has to be set to "true" or "false". This property is to control the audio output only when the input file contains audio and video streams.

As a workaround "audioread" audioread can extract audio from MPEG-4 (.mp4, .m4v) video files on Windows 7 or later, Macintosh, and Linux, and from Windows Media Video (.wmv) and AVI (.avi) files on Windows 7 (or later) and Linux platforms.
