NullPointerException in MovieCreator.build

[GoogleCodeExporter]

I have Android app which uses mp4parser 1.0.2-SNAPSHOT for reading files. I am 
receiving the following crash reports from some devices:

java.lang.NullPointerException
       at com.googlecode.mp4parser.authoring.container.mp4.MovieCreator.build(SourceFile:48)
       at com.googlecode.mp4parser.authoring.container.mp4.MovieCreator.build(SourceFile:35)
       at ru.roadar.android.audio.Mp4ParserAudioMuxer.mux(SourceFile:57)
       at ru.roadar.android.video.VideoRecorder$VideoAudioMuxer.run(SourceFile:641)
       at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080)
       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573)
       at java.lang.Thread.run(Thread.java:856)

In fact, it's possible for IsoFile.getMovieBox to return NULL, so it may be 
makes sense to add a guard against it.

Well, no MP4 file might ever have no moov. 
If it doesn't have moov it's not an MP4. You most likely didn't compile the 
aspects

I have the same error. 
It occurs when I press continuously pause and resume button.
But I checked file path and file size, they are both != null.
What should I do?
this is log
java.lang.NullPointerException: Attempt to invoke virtual method 
'java.util.List com.coremedia.iso.boxes.MovieBox.getBoxes(java.lang.Class)' on
