Ok, what you suggest sound logical to me. Currently, I
have done a small trick to prevent this problem. What

repeat the previous packet. Hence, all the breaking
portion is filled with previous packet. This trick

I think jitter buffering is more correct way to solve
this problem but I think this is not so easy. Is there
got any source code to reference from?
