Problem when append 2 or more mp4

[GoogleCodeExporter]

Using code from appendExample in my android application I try to append the 3 
videos found in example resources (1365070268951.mp4, 1365070285923.mp4 and 
1365070453555.mp4) I notice that the result video is more speedy then the 3 
videos. 

I am using the final version from https://github.com/sannies/mp4parser (the 
last update was yesterday). I am using ADT on Windows.

Maybe this will help you to tell me what I am doing wrong.

Information from output.mp4
