Method for pushing video code stream to cloud server through local area network

Technical Field

The invention relates to the technical field of video monitoring systems, in particular to a method for pushing a video code stream to a cloud server through a local area network.

Background

The monitoring is a physical basis for real-time monitoring of key departments or important places in various industries, and management departments can obtain effective data, image or sound information through the monitoring and memorizing system, timely monitor and memorize the process of sudden abnormal events, provide high-efficiency and timely command and height, arrange police strength, process cases and the like, and have raised a strong digital wave worldwide along with the rapid development and popularization of current computer application, and the digitization of various devices becomes a primary target of safety protection.

In general office buildings, communities and the like, video monitoring systems are provided, a video collected by a camera is stored in a DVR/NVR (digital video recorder/video recorder), a computer is deployed in a monitoring room and used for checking videos, video code streams cannot be pushed to the cloud end, other cloud end intelligent building systems cannot be accessed, video monitoring equipment in a local intranet cannot push code streams to a cloud end server under general conditions, and monitoring cannot be checked on the external network.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a method for pushing a video code stream to a cloud server by a local area network, and the invention realizes the viewing of a monitoring video in an external network.

The invention provides the following technical scheme: a method for pushing a video code stream to a cloud server by a local area network comprises the following specific steps:

s1, sending an Http request to the plug flow program, providing a name of a video stream to be accessed, wherein the plug flow program runs on an intranet, and an external cloud server address needs to be accessed during access, and is penetrated by Frp;

s2, the flow pushing program receives the request, judges whether the flow is pushed to the flow media server, if yes, returns the flow address directly; if not, judging whether the upper limit of the push path number is reached, if not, directly pushing the video stream and returning to a stream address, and if so, canceling the earliest push thread and then pushing the stream and returning to the address;

and S3, playing the video stream according to the returned address.

Preferably, in S1, the intranet may obtain the real-time video code stream of the camera through the RTSP protocol, and currently, common mainstream camera brands all support the RTSP protocol, and may directly obtain the code stream in the local intranet.

Preferably, in S2, a Nginx with an RTMP module is deployed as a streaming media server, which is responsible for receiving push of RTMP and providing external access.

Preferably, the stream pushing program uses FFMPEG to push stream, and converts the RTSP code stream in the intranet camera into an RTMP code stream with low code rate and resolution and pushes the RTSP code stream to the streaming media server.

Preferably, the stream pushing program provides an http interface externally, when a certain path of video is accessed externally, the monitoring device name to be accessed is transmitted by calling the interface, the program starts the FFMPEG to push the path of video code stream and returns the RTMP address for implementing the code stream in response, and if the path number set by the connection pool is reached, the previous code stream pushing is automatically disconnected according to the time sequence.

Preferably, frp intranet penetration is realized by deploying frps on a cloud server with a public network ip and deploying frpc on a local monitoring intranet server.

Compared with the prior art, the invention has the following beneficial effects:

according to the method for pushing the video code stream to the cloud server by the local area network, the purpose that the video code stream is pushed to the cloud server by the internal network is achieved through technical means, and the purpose that the real-time video of the video monitoring equipment is accessed to the external network is achieved.

FIG. 1 is a schematic view of the structure of the present invention.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure, and in order to keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known parts of the disclosure are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

Referring to fig. 1, a method for pushing a video stream to a cloud server through a local area network is characterized by comprising the following specific steps:

and S3, playing the video stream according to the returned address.

In monitoring a local intranet, a real-time video code stream of a camera can be obtained through an RTSP (real time streaming protocol), and currently common mainstream camera brands all support the RTSP and can directly obtain the code stream in the local intranet.

In the monitoring local intranet, a server is deployed, and a Nginx with an RTMP module is deployed as a streaming media server and is responsible for receiving the push of the RTMP and providing the push for external access. Since HTML5 provides support for the RTSP video stream, the RTSP stream of the camera cannot be played directly in web applications, and the RTSP is a better choice than the RTSP.

The reason for reducing the code rate and the resolution is to reduce the network overhead when accessing the external network and cope with a low-bandwidth scene.

The method comprises the steps that a developed dynamic stream pushing program is deployed on a monitoring local server, as a plurality of monitoring devices are arranged in a common office building and a cell, if videos of all the monitoring devices are pushed to a streaming media server at the same time, a server with very high performance is needed, the program maintains a connection pool, video code streams are pushed as required, an http interface is provided externally, when a certain path of video needs to be accessed externally, the name of the monitoring device needing to be accessed is transmitted by calling the interface, the program starts FFMPEG to push the path of video code streams and returns RTMP addresses of the implementation code streams in response, and if the number of paths set by the connection pool is reached, the code stream pushing before the path is automatically disconnected in a time sequence.

According to the scheme, the frp is used for intranet penetration, frps is deployed on a cloud server with a public network ip, and frpc is deployed on a local monitoring intranet server to achieve intranet penetration.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
