In h264 decoder, buffering?

In h.264 decoder, When the input is stream, how is the size of the buffer?
In my application, one frame encode -> decode and store it -> the otherframe encode -> decode and strore continueously. but,h264 decoder is not operated by frame by frame, and delayexists.
So, I plan to do buffering the input stream of decoder, but I don't know buffer size?
In simpledecoder.cpp, DataIn.SetBufferPointer(cVideoData,VideoDataSize); andDataIn.SetDataSize(VideoDataSize);
That is, when the value of VideoDataSize is varied, howset it?
