step a, a user sends a playing request of a real-time video aiming at one or more cameras to a video server through a video terminal, wherein the playing request comprises user identity authentication information.
The method comprises the steps that a user binds a raspberry group and a mobile phone number on a registration page provided by a video server, when the user sends a playing request, the video server sends a short message verification code to the mobile phone number, after the user inputs a correct short message verification code on the playing request page, the video server sends an mqtt message to a raspberry group terminal where one or more cameras are located, the user can bind one or more raspberry groups, and each raspberry group is connected with one or more cameras.
And b, after the video server receives the playing request of the user, the user identity is verified according to the user identity verification information, if the verification is passed, the video server dynamically generates a streaming media playing address according to the playing request and sends the streaming media playing address to the video terminal, and simultaneously sends an mqtt message requesting playing to a raspberry sending terminal of a local area network where the one or more cameras are located, wherein the dynamically generated streaming media playing address comprises a unique code, a timestamp and a unique check code of the user.
And c, after receiving the mqtt message requesting to be played, the raspberry dispatching terminal calls an ffmpeg service to collect real-time video streams of the one or more cameras, and pushes the collected real-time video streams to the nginx server through an rtmp video push protocol.
And d, the video terminal is connected with the nginx server according to the playing address to play the real-time videos of the one or more cameras.
The step a further comprises:
and starting the raspberry pi terminal, sending connection information to a prefabricated mqtt server by the raspberry pi terminal, wherein the connection information comprises prefabricated basic information of the raspberry pi terminal and an mqtt message theme which can be received by the raspberry pi terminal, and the raspberry pi terminals are one or more.
The step b of sending the mqtt message requesting to be played to the raspberry pi terminal where the one or more cameras are located further includes:
and the video server analyzes an mqtt message theme corresponding to the play request according to the play request and sends the mqtt message containing the mqtt message theme to the raspberry pi terminal.
The mqtt message requesting to be played in the step b further comprises:
basic information of one or more cameras needing to push the real-time video is needed, the nginx server receives the address of the real-time video stream, and the basic information comprises the ip address, the port address and the account password of the one or more cameras.
And e, the user sends a playing cancellation request to the video server through the video terminal, the video server sends an mqtt message for canceling playing to the raspberry sending terminal of the local area network where the one or more cameras are located according to the received playing cancellation request, and the raspberry sending terminal cancels pushing of the real-time video stream according to the mqtt message for canceling playing.
The dynamic generation of the streaming media playing address can be realized by configuring parameters such as the rtmp service provided by nginx based on the rtmp service provided by nginx
rtmp {
server {
listen 1935;
application rtmplive {
live on;
record off;
}
}
}
All requests starting with rtmp:// ip: 1935/rtmplive/can get the correct response through this configuration. The server side can generate the following address rtmp:// ip:1935/rtmplive/A user unique code/current time/unique check code according to the A user request, and the server side can generate the following address rtmp:// ip:1935/rtmplive/B user unique code/current time/unique check code according to the B user request.
The video terminal may be a mobile phone, tablet, computer or other network-enabled device.
