Can not edit tag info of MP4 file about mp4parser HOT 5 CLOSED

Please help me soon friend, I can not find any mp4parser except you.

Are you using the IsoViewer or the IsoParser? 
The problem will most likely be that the additional data changes the offset of 
the actual video data which is referenced from within the file. You will also 
need to modify the ChunkOffsetBox to correct that.

Yes, I'm using isoviewer-1.2.jar

But how can I alter ChunkOffsetBox friends ?
Cann you note down some points

It's no defect. isoviewer is not a metadata editor. It edits boxes. If by your 
edit the offsets in the file become corrupt it's nothing the isoviewer should 
correct by himself.
Closing the defect. If you still require assistance please send a message to 
the mp4parser discussion group.
