Problems solved by technology

These protocols are not friendly to browsers at present. In the period when IE browser was still popular, these protocols could be connected through ocx plug-ins. However, with the decline of IE and the current popularity of Chrome and Firefox browsers, native Plug-ins are becoming more and more unfriendly, and it will become more and more difficult to access surveillance video through plug-ins

Abstract

The invention discloses a platform for automatically realizing video format conversion processing, which is characterized in that a set of high-performance streaming media service framework is constructed, and multiple streaming media protocols of rtmp / rtsp / hls / http-flv are supported. Linux, macos, windows, ios and an android platform are supported, and the supported coding formats comprise H264, AAC and H265; an adopted model is multi-thread IO multiplexing non-blocking programming (epoll is adopted under linux, and select is adopted by other platforms); the framework is developed based on C++11, use of a bare pointer is avoided, memory copying is reduced, codes are simple and reliable, concurrency performance is excellent, and under a linux platform, the advantages of a multi-core CPU can be fully utilized by a single process; the CPU and network card performance can be maximized; and the performance limit of the 10-gigabit network card can be easily and meanwhile, extremely low time delay can be achieved while high performance is achieved, and a picture is opened in seconds.

Description

technical field [0001] The invention belongs to the field of electronic information technology software video, relates to a method for fast video format conversion, and in particular to a platform for automatically realizing video format conversion processing. Background technique [0002] In recent years, major cities in China have gradually promoted the process of safe city projects. In the fields of security, transportation, etc., the scale of the video surveillance market has grown. And with the popularity of indoor home cameras and vehicle recorders, video surveillance can be said to be ubiquitous in people's lives. But at the same time, due to the block construction of various industries and departments, the current video surveillance system has multiple heterogeneities such as sources, channels, and terminals, which poses a severe challenge to the efficient integration of video surveillance resources. Therefore, how to break through the technical bottleneck of interc...
