You can use pymedia to do that( http://pymedia.sourceforge.net )
ATM writing of avi files is not supported( mpeg only ), however you can do a simple fix for that if you're interested.

The way it works is it parses AVI file, gives you frames( audio, video, text ) and then you can decode video into YUV frames and convert it into the regular BMP image as string which I suppose you meant by "matrix".
