S103, video stream data sent by the data acquisition end after the stream pushing task is received is obtained.
Specifically, after receiving the plug-flow task sent by the cloud, the data acquisition end acquires video stream data acquired by a corresponding camera or camera, and sends the video stream data to the cloud. And the cloud end receives the video stream data. The cloud can authenticate the data acquisition end or the video stream which tries to access, and illegal equipment access is refused. The cloud end can register, discover and manage the data acquisition end equipment, and can issue an upgrade package, control state information and the like to equipment such as a camera or a video camera, so that the cluster management function of the equipment such as a front-end camera or the video camera can be conveniently realized, and the equipment management capacity, the operation and maintenance capacity and the expansion capacity are greatly improved.
And S104, sending the playing address of the video stream data to the client.
Specifically, the cloud stores the video stream data after receiving the video stream data sent by the data acquisition end, so that the local storage space and flow of a user are not occupied, and meanwhile, the user can conveniently review, download, share, delete and the like.

And the data acquisition end stops acquiring and sending the video stream data after receiving the pushing task, so that the video stream data can be acquired as required.
Further, step S202 "sending a stream pushing task to the data collecting end according to the video stream data request" in this embodiment may specifically include the following steps: performing identity authentication on the user according to the user identification in the video stream data request; and if the verification is passed, sending a stream pushing task to the data acquisition end according to the video stream data request.
Specifically, the cloud end obtains a user identifier in a received video stream data request, can perform identity verification on the user identifier according to a pre-stored registered user identifier table, and sends a stream pushing task to the data acquisition end according to the video stream data request if the user identifier passes the verification.
Further, the step S202 "sending the stream pushing task to the data acquisition end according to the video stream data request" in this embodiment may specifically include the following steps: searching corresponding video stream data in the cloud according to the video stream identification in the video stream data request; and if the corresponding video stream data does not exist, sending a stream pushing task to the data acquisition end according to the video stream data request.

By encrypting the video stream data, even if the playing address of the video stream data obtained by a third party cannot be played, the video stream data obtained by packet capture cannot be normally displayed, and the safety of transmitting the video stream data to the cloud is ensured.
Further, the step S204 "sending the playing address of the video stream data to the client" in this embodiment may specifically include the following steps: carrying out protocol conversion on video stream data to obtain video stream data of various protocol types; and sending the playing addresses of the video stream data of the multiple protocol types to the client.
Specifically, in video transmission, in order to ensure real-time performance, camera video streams are generally transmitted by using an rtsp protocol, part of live cameras are generally transmitted by using an rtmp protocol, and finally, a specific player or a client performs protocol analysis and transcoding playing. In order to improve the convenience of video stream playing, after the cloud end receives video stream data sent by the data acquisition end, protocol conversion can be carried out on the video stream data, namely the video stream data of rtsp or rtmp protocol type sent by the data acquisition end is converted into video stream data of various protocol types such as rtsp, rtmp, hls, http-flv, ws-flv and the like, playing addresses of the video stream data of various protocol types are generated, the playing addresses of the video stream data of various protocol types are sent to the client end, and the client end selects a corresponding playing address according to the protocol type supported by the client end.

And when the client end is detected to finish the requirement on the video stream data, sending a finish stream pushing task to the data acquisition end, so that the data acquisition end stops sending the video stream data after receiving the finish stream pushing task. When a user sends a video stream data request through a client, the data acquisition end acquires the video stream data, and when the requirement on the video stream data is finished, the data acquisition end stops acquiring the video stream data, so that the video stream data can be acquired as required, and the pressure and flow cost of a server are reduced. By performing authentication on the user and encrypting the video stream data, the data security can be ensured. Through protocol conversion, more use scenes can be expanded, and the convenience and expandability of video stream playing are improved while the video delay is not increased.
