How to handle the file more than 2G bytes when convert h264 raw stream to mp4 with MP4V2 lib on android platform?

I convert a h.264 raw stream file more than 2G bytes(>0x80000000) to mp4 file, with mp4v2 lib , but it can not be played. But if I read the raw file less than 2G (<0x80000000) then convert to mp4v2 with the same way, the mp4 file can be played. I try that in my pc with 64 bit x86 system, it work normally. So the way to convert mp4 file is right, the problem must be the mp4v2 lib convert unsigned and signed unproperly on arm 32 bit android system. Can someone help me to solve it ? Thank you very much.
