VideoReader: audio from avi

Hello Matlab users,

do you know how to import (synchronous) audio from a video file? I use the following code to read the first 10 video frames, but is there a method to import the audio from the avi container?

readerObj = VideoReader(filename);
v = read (readerObj, [1 10]);

Best regards, Philipp

Have you tried:

   [y,Fs] = audioread('myFile.avi');

If this doesn't work you should get the output from

    info = mmfileinfo('xylophone.mpg')
    audio = info.Audio
    video = info.Video

and determine if the audio portion is supported from MATLAB.

To do this requires a quite new version of the Computer Vision Toolbox; see the class method here
