FFMPEG (ii)-Universal multiplexer One: Technical points As mentioned in the previous article, the reuse structure of the MP4 type differs from other types, such as mp4,mov,flv, where the H264 data does not contain descriptive information such as SPS,PPS, to reduce overhead, The same is true for AAC data, which requires converting the previous 7-byte Adts header to a two-byte frame length. FFmpeg provides something called the filter filters to do this.

The design pattern of the object behavior class, sorting and distributing synchronization events. Alias Dispatcher(dispenser) The reactor pattern is a common pattern for handling concurrent I/O, and is used for synchronous I/O, with the central idea of registering all I/O events to be processed on a central I/O multiplexer while the main thread blocks on the multiplexer; once i/ o The event arrives or is re

1gb/s level, can be understood as basically not time-consuming. The following illustration is a comparison of several common I/O models: Java NiO is the second or third form: The second: In a while loop inside constantly check Selector whether there are events triggered Selector.select (1000) The third: Selector.select () Checks whether there is a ready event, and if not, it blocks until the Ready event function returns. reactor There is an article very well written: http://www.blogjava.net/DL

Multiplexing (WND) is the use of two or more different wavelengths of optical carrier signals (carrying various information) at the transmitter through the multiplexer (also known as the Wave-filter, multiplexer) converge and coupled to the transmission of the same fiber in the optical circuit; at the receiving end, the Multiplexer ( Also known as the splitter o

, poll, and Epoll are essentially synchronous I/O, first block a waiting socket, and block to copy data from the kernel to the user's memory.The differences between select, poll, and Epoll, such as the following table:1.10. Two I/O multiplexing modes: Reactor and ProactorIn both modes the event multiplexer feedback to the program information is not the same:The 1.Reactor mode shows that you can read and write (send and receive) operations.The 2.Proact

With the advent of IO multiplexing technology, there are many event processing modes. The synchronous I/O model is typically implemented by the reactor pattern, while the asynchronous I/O model is implemented by the proactor pattern. Reactor mode: As shown above, the reactor mode is also called a reactor or reactor, the processor that implements the registration descriptor (HANDLE) and the event (EventHandler), and when an event occurs, the event Reator

a TCP tunnel in "Write a proxy usage you know". The program consists of three parts: N: 1 connection forwarding service and 1: n connection forwarding service, socks proxy service. I followed his ideas and used muduo to implement these three programs. The difference is that I didn't do data obfuscation, so I couldn't use it to flip the legendary Wall.
