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.

In this paper, the measurement methods of optical fiber and optical fiber communication system are briefly introduced, this paper mainly introduces optical fiber measurement: single-mode fiber Mode field diameter, optical fiber loss, fib
Most of the integrated City Line systems are installed using traditional optical fiber systems; In this case, the appropriate optical installation should be done using the design methods already discussed. The system proved to be feasible through countless successful cases, reliable, stable, mature and excellent.
Another recent installation technology, known as "gas-blown fiber," has been developed in the
1. Preface
A cylindrical media waveguide consists of three parts: Core, package layer, and coating layer. Generally, the diameter of the core of a single-mode or multi-mode optical fiber is 5 ~ 15 μm and 40 ~ 100 μm, with a diameter of about 125 ~ 600 μm. The processed optical fiber end face is ideally a smooth plane. However, in reality, the processing of the optical f

1. Briefly describe the composition of optical fiber.
A: The optical fiber consists of two basic parts: the core, package layer and Coating Layer Made of transparent optical materials.
2. What are the basic parameters used to describe the trans
Fiber: Microsoft joins windows to better port Unix server applications to Windows. Therefore, this article does not really have much application value, just to make the notes more complete.
After reading this chapter, I feel that the fiber is a smaller running unit than the thread. You can split a thread into multiple fiber threads, and then manually convert th
After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every several years, the continuous development of network applications puts forward higher bandwidth and other related performance requirements to people. With the popularization and application of gigabit and 10-Gigabit networks, in our traditional cabling system, currently, copper cable systems can only be used for
Most of the integrated cable systems are installed using traditional optical fiber systems. In this case, appropriate Optical Fiber installation should be carried out using the discussed design methods. The system has proved to be feasible, reliable, stable, mature, and excellent through numerous successful cases.
Recently, another installation technology called "air blow optical

fiber/Fiber DriveIn the operating system, in addition to processes and threads, there is a less-applied fiber (fiber, also called co-process). Fibers are often compared to threads, and for the operating system, they are relatively light-weight running states. Fiber turndown
Today's communication networks are composed of multiple interconnected optical and electrical components to support high-speed video, voice, and data transmission. The backbone of the network is optical fiber. Its design and manufacture are used to optimize attenuation and dispersion, making the network the most cost-effective and cost-effective network. A new optical fiber design is widely accepted in the
The optical fiber access network has a lot to learn about. Here we mainly introduce the application specifications of optical fiber cabling in the optical fiber access network. As fiber access networks have been widely used in China only in recent years, telecom operators generally feel that they lack experience in bui

In the operating system, in addition to processes and threads, there is a less applied fiber (fiber, also known as the coprocessor). Fibers are often compared to threads, and to the operating system, they are relatively lightweight operation states. Fiber
There are many things worth learning about in the Metro optical fiber cable network. Here we mainly introduce the comprehensive comparison of the optical fiber lines in the Metro optical fiber cable network. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Secon
The optical fiber is the abbreviation of the optical fibre, which is composed of fine glass wire about 0.1mm in diameter. It is transparent and slender, although it is thinner than hair, it has a guided wave structure which encloses the light and propagates along the axial direction. Optical fiber communication is due to the mysterious structure of optical fibers developed by the optical wave as the carrier
After a long period of development, many users are familiar with the optical fiber connection technology in the optical fiber access network. Here I will share my personal understanding and discuss with you. The development of optical fiber connection technology (such as splicing technology to replace the crimping technology) makes the application of optical
1. After the Optical Fiber Fusing splicer is enabled, the screen will not be bright, and the wind shield will be turned on, and the horizontal lighting on the electrode seat will not be bright.
Solution:
1> check whether the power plug-in seat is properly inserted. If not, try again.
2> check whether the power fuse is disconnected. If it is disconnected, replace the backup fuse.
2. The optical fiber can be
