Common video coding and decoding standards
Many video codecs can be easily implemented on personal computers and consumer electronics, which makes it possible to implement a variety of video codecs at the same time, which avoids the fact that some dominant codec affects the development and promot

A. How long does the buffer take, for example, ms or 50 ms;
B. The number of bytes received per second;
BufferSizeM = dwBytesPerSec * dwLatencyInMilliseconds/1000;
