A method of real-time streaming across network boundaries

Abstract

The invention discloses a real-time stream transmission method across network boundaries. It specifically includes the following steps: as the starting point of stream transmission, the server receives the signaling of stream transmission, and performs media information verification on the original stream RTP, RTSP, RTMP, and UDP; unifies the streams in RTSP, UDP, and RTP formats through a transcoder Transparent transmission into RTMP format; FFMPEG component converts RTMP into HTTP-FLV and pushes it to the boundary; boundary corresponds to FFMPEG component one-to-one, and FFMPEG’s streaming method actively crosses the boundary to transmit the real-time stream to the intranet via HTTP; SRS receives HTTP ‑FLV stream, multicast into RTMP format at the same time; Intranet client player plays RTMP video stream. The beneficial effects of the present invention are: reduce the entire playback link, facilitate tracking; reduce server storage pressure; be generally applicable to http-based cross-network real-time stream transmission scenarios; realize pluggable cross-border components; zero intrusion, reduce development work low volume; less integrated middleware, easy to deploy; low latency, improving user experience.

Description

technical field [0001] The invention relates to the technical field of data interaction, in particular to a real-time streaming transmission method across network boundaries. Background technique [0002] The public security network involves the public security information network, the intranet, and the dedicated video network, which are strictly physically separated from the Internet, and "one machine for two purposes" is prohibited. The data interaction between the video private network and the public security intranet is realized through the gatekeeper or security boundary. Compared with the ferry method of the gatekeeper, the security boundary has a great advantage in real-time performance. [0003] In the data interaction between the general video private network and the public security intranet, watching videos is realized through a gatekeeper. It is necessary to transcode the stream into sliced ​​files, and then FTP to the public security intranet. This method has th...

[0003] In the data interaction between the general video private network and the public security intranet, watching videos is realized through a gatekeeper, which needs to transcode the stream into slice files, and then FTP them to the public security intranet. This method has the following problems: The road is long, it is difficult to track abnormal problems; the development workload is heavy; the video watched has a large delay, which cannot be used for real-time viewing and investigation of on-site conditions; when the public security intranet receives sliced ​​files and assembles them into a playlist, it is easy to make mistakes; the way of FTP ferry, file transfer It is difficult to accurately monitor the state
