Answer 1

[Walter Roberson]

In MATLAB, you have no choice: there is no routine that can read both the audio and video, just routines that can read audio and routines that can read video.

Answer 2

[Daniel Shub]

Do you want a pure MATLAB based solution? This is one of those things I would not do in MATLAB. In Linux

ffmpeg -i audiovideo.avi audio.mp3

I am pretty sure ffmpeg can handle a number of different video and audio types and might even be available for Windows.
