Bit rate control is actually a coding optimization algorithm, which is used to control the video stream size. So what is the purpose of its control? We can imagine that the same video encoding format, the code flow is large, it co

meaning. In the memory management of the operating system, there is a kind of important algorithm is the memory page replacement algorithm (including FIFO,LRU,LFU and so on several common page substitution algorithm). In fact, the core idea of the cache algorithm and the memory page replacement algorithm is the same: it is
