formatsThe processing of encapsulation formats using FFmpeg is done primarily through Avformat. There are 3 examples of processing of encapsulation formats:Encapsulated Format Converter: The simplest ffmpeg-based package Format converter (no codec)AV Splitter Simplified version (demuxer-simple): Simplest ffmpeg-based package format processing: AV splitter simplified version (demuxer-simple)AV Splitter (demuxer): The simplest ffmpeg-based package format processing: AV Splitter (demuxer)AV

This is a creation in Article, where the information may have evolved or changed. I began to become a Gopher 10 months ago, without turning back. Like many other gopher, I quickly discovered that simple language features are very useful for quickly building fast, scalable software. When I first started learning Go, I was playing with a different multiplexer (multiplexer) that could be used as an API server

The use of basic IO and the simplest example of blocking the server are described in the previous article, and this article introduces the relevant content of the following NIO, which you can refer to in the previous share: Basic knowledge and concepts of network IO General IO and Bio server Use of NiO with server Hello World Netty Getting Started with server Hello World Netty in Layman's NIO, also known as New-io or Non-blocking-io, is understood as non-block

the request model .This model lacks elastic scalability, the number of processing threads on the server and the number of concurrent accesses to the client are 1:1, and the number of threads is inflated resulting in a significant decrease in efficiency, even when the thread's stack overflows and the new thread cannot be created.Pseudo-Asynchronous IO communicationUse the thread pool to be responsible for connections.encapsulates a user's request into a task and then throws it into the thread po

external third-party sensor is used only when the external sensor is connected (and has limited performance). The I2C interface used to send motion data is optional, because the SPI interface is reused, so only two is selected.MPU9250 I2C Interface:I2C interface for third-party sensors This interface is used to connect to the external Third-party sensor, that is, if you feel that the MPU9250 9-axis sensor is not enough, you can also external third-party sensors, such as pressure sensors.This ad

to install, Walkair systems can transmit carrier based carriers, providing class TDM (Time division Multiplexing) services and efficient IP connectivity.As a combination of this best solution, Alvari base allows operators to have unprecedented flexibility in selecting customer addresses and providing services. Alvari base enables operators to quickly and efficiently create broadband wireless access systems and provide solutions that have the benefits of Walkair and breeze access on a single inf

achieve error-free transmission . If the channel bandwidth W or signal-to-noise ratio S/n has no upper limit (of course, the actual channel can not be such), the channel limit information transfer rate C also has no upper limit. The transmission rate of information that can be achieved on the actual channel is much lower than that of Shannon's limit transmission rate. The Nyquist theorem indicates that the rate of transmission of the code element is limited;Shannon formula gives th

broadcasting sector are currently engaged in the development of interactive video services, which, by convention, have a two-way high-bandwidth Fibre Channel, while the broadcasting department has been operating video business for a long time and has a large number of one-way High-bandwidth cable video lines. The advantage of the telecommunications sector is the existing Fibre Channel, but the Subscriber access line is still twisted, bandwidth is not enough, the solution is to use asymmetric di

The information panel is the installation equipment of the information module, and it is also the lid of the concealed square box. Here we choose the two-port information panel, one is the information mouth, one mouthful is the telephone mouth. (Figure 3) 5. Crystal Head Crystal Head Here we choose to be RJ45 crystal Head, this enables us to unify the use in the RJ45 information module and the information panel, such convenient one network cable simultaneously over the data and the telephone i

Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

has two SC Optical Fiber interfaces. From figure 2 and Figure 3 right figure Switch SC interface appearance can be seen that it and RJ-45 interface is very similar, but SC interface seems more flat, the gap is lighter. Mainly look at the contact chip is what type, if it is 8 pieces of Copper shrapnel, It is the RJ-45 interface, and if it is a copper column inside is SC Fiber Interface. 3. AUI interface and BNC The AUI interface is specially used to connect coarse

contains audio data and auxiliary information data. The data transmission process can be divided into three parts: video data transmission period, Island data transmission period, and control data transmission period. Video data transmission period: video pixel signals are transmitted on the HDMI data cable. The video signals are encoded to generate three channels (that is, three tmds data information channels, each with 8 bits) A total of 24-bit video data streams are input to the HDMI transmi

interface Common Ethernet interfaces include AuI, BNC and RJ-45 interfaces, as well as FDDI, ATM, Gigabit Ethernet and so on all have corresponding network interfaces, the following describes the main LAN interfaces. (1). AuI PortThe AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10base-5 network th
