Application stucks when reading large mp4 files

[lonely-lockley]

Application stucks forever when parsing media boxes larger tan 2Gb. No exceptions generated. This happens with RandomAccessFile sources only.
The problem is in MP4InputStream.skipBytes() method:

while(l<n) {
        if(in!=null) l += in.skip((n-l));
        else if(fin!=null) l += fin.skipBytes((int) (n-l));
}

This cast to int on line 3 causes int to overflow and skipBytes always returns zero as a result which leads to an endless cycle.
