 http://stackoverflow.com/questions/17162362/using-mp4parser-if-i-append-more-videos-the-audiostream-gest-out-of-sync?rq=1 

but no improvement.

What is the expected output? What do you see instead?
i have used mp4parser for dynamic pause and record video capture with max 6 
second recording. its working fine when recorded video with minimum 
pause/record, if i tried with more than 3 pause/record mean the last video file 
not get merged properly with audio. audio playing for 6sec and video oniy for 
5sec. could anybody know the prob in it. i had set framerate/sec as 30.

What version of the product are you using? On what operating system?
I am using isoviewer-2.0-RC-18.jar on android platform.

Is it planed to add a proper support for merging videos to mp4parser? I mean 
that if the library is supposed to support merging of videos it should handle 
overflow video/audio tracks and don't include then in the result file. It 
rather should not be expected that the client code of the library should do it.

The title and description of this report should be changed as this issue may 
appear already when merging just two videos. You don't have to merge more, 
although the more you merge the more likely it is to run into those issues.
