Ciphertext h264 video live broadcast and on-demand platform based on live555 framework and ffmpeg library

Abstract

The present invention provides a kind of ciphertext H264 video live broadcast and on-demand platform based on live555 framework and ffmpeg storehouse, comprising: a streaming media server and an external storage server based on the live555 framework; the streaming media server and the external storage server are connected through a network; the Streaming media server comprises live555 live broadcast proxy logic server and live555 order logic server; Described external storage server is provided with ciphertext H264 video transcoding module and ffmpeg storehouse; Between live555 order logic server and external storage server, communicate by TCP protocol, for Therefore, a TCP client is built on the live555 VOD logic server, and a TCP server is built on the external storage server. The invention realizes the live broadcast of the ciphertext video stream and the on-demand broadcast of the ciphertext video files in the urban security monitoring system, and can ensure the real-time requirement of the ciphertext video transmission and ensure better user experience.

Description

technical field [0001] The invention relates to a video platform applied to a city security monitoring system, in particular to a ciphertext H264 video live broadcast and on-demand platform. Background technique [0002] The Live555 streaming media framework is a cross-platform C++ open source project that provides solutions for streaming media. It realizes the transmission of standard streaming media and provides support for standard streaming media transmission protocols such as RTP / RTCP, RTSP, SIP, etc. It is mainly used to process audio and video of streaming media and realize real-time push of media; ffmpeg is a set of open source computer programs that can be used to record, convert digital audio and video, and convert them into streams. [0003] With the rapid development of video codec technology and network technology, network video communication technology has become a part of people's life. However, in an open network, video information is vulnerable to human atta...

Problems solved by technology

[0004] Due to the choice of the encryption method, the structure of the encrypted video is not destroyed at all, and its streaming transmission is completely achievable. However, unlike plaintext video streaming, ciphertext video streaming mainly faces two problems. The first is to ensure that the ciphertext video Reliability during transmission, once the key frame is lost, it will affect the decryption of the encrypted video by the ciphertext player; second: Encapsulation of the ciphertext video, once the frame structure and bytes of the video change, it will not be able to decrypt and play later
