Compared with traditional analog transmission products and copper-based systems, the third generation digital optical fiber product provides a unique advantage: Performance consistency. No matter how long the optical fiber is used, the baseband video and audio performance will always remain high in the system and provide consistent performance. Point-to-Point Distribution of AV signals can easily implement digital optical fiber technology. Topology ca

Failure phenomenon: Win7 under the use of a key AV function, originally in the middle of the bottom of the screen will have mode status bar display, and in the computer modified WIN8 system, a key AV button does not work. Reason Analysis: Win8 system, a key AV function canceled in the screen Display mode state transition bar, do not see the cue bar belongs to

AV Terminator for one months, many friends already know the Golden Hill av Terminator kill can restore anti-virus software function, and then upgrade anti-virus software can solve a lot of problems. Whether the Netizen is the user of poison tyrant, the program of poison tyrant can solve the problem for netizen, it is our most happy thing. Now we are looking at a new trend: The number of

These two days began with the radio and television project sophomore Summer school curriculum design. This primary course covers the production of video players based on FFmpeg + SDL, which focuses on the basics of AV development. As the content of the course is more suitable for beginners who do not have audio-visual basis, they also recorded part of the content and uploaded it to the Internet for beginners to learn ffmpeg development.This is my firs

The YUV/RGB handlers and PCM handlers that are described in the first two articles are handlers of the AV raw data. This article begins with a description of the audio stream handler. The program described in this article is a video bitstream handler. The location of the video stream in the video player is shown below.The program in this article is a code stream parsing program. The program can analyze the basic unit Nalu from the H. A stream, and can
