Example 1:
fig. 1 shows an implementation flow of a method for acquiring a surveillance video according to an embodiment of the present invention, where the method is applied to a device management server, and the process is detailed as follows:
in step S101, a video request instruction sent by a user terminal is obtained, and a push state of a corresponding monitoring device is detected according to the video request instruction.
In a specific application, the process of video playing needs to involve the following four devices:
1. and the monitoring equipment is used for acquiring monitoring videos, such as a camera device and the like.
2. The Streaming media server is configured to receive and issue video stream data pushed by the monitoring device, for example, a Real Time Streaming Protocol (RTSP) or a dynamic code rate adaptation (HLS) Streaming media server.
3. And the user terminal is used for acquiring video stream data according to the network address of the streaming media server to realize video playing, such as a mobile phone, a mobile computer and the like.
4. And the equipment management server is used for monitoring and controlling the working states of the monitoring equipment and the streaming media server, maintaining equipment information and updating in real time.
In one embodiment, the push status of the monitoring device includes video stream data being pushed and video stream data not being pushed. The device management server detects the push state of the corresponding monitoring device, namely, judges whether the corresponding monitoring device is pushing the video.
In this embodiment, the device management server obtains a video request instruction sent by the user terminal, and searches for a corresponding monitoring device in the pushed video stream list to obtain a pushed state. The pushed video stream list includes status information of all monitoring devices that are performing video stream pushing.
In the embodiment of the invention, a user selects to play the video, wherein the user needs to designate the main/sub code stream of the video when selecting to play the video. The main code stream and the sub code stream are two different coding formats generated by the monitoring equipment, the main code stream is used for local storage, the sub code stream is suitable for image transmission on a low-width network, and the dual code stream can meet the requirements of two different bandwidth code streams of local transmission and remote transmission.
Taking an application scenario as an example, a user selects to play a video on a user terminal, and designates the video as a main code stream, the device management server receives a video main code stream request sent by the user terminal, searches a push video stream list, and judges whether a corresponding monitoring device is pushing the main code stream of the video requested to be played.

In this embodiment, when the device management server finds that the monitoring device corresponding to the video request instruction is pushing a video in the video stream pushing list, the device management server increases the pushing number of the video main/sub stream of the monitoring device in the video stream pushing list, and sends the playing information of the video to the user terminal, and the user terminal can request the streaming media server to play the video through the playing information.
Taking an application scenario as an example, a user specifies that a video requested to be played is a main code stream, the device management server finds that the main code stream pushing number of the corresponding monitoring device in the pushed video stream list is 2, namely the monitoring device is pushing, the main code stream pushing number is increased in the pushed video stream list, the device management server returns a Uniform Resource Locator (URL) address of the main code stream to the user terminal, and the user terminal requests the streaming media server to play the video according to the URL address.
In this embodiment, when the device management server finds that the corresponding monitoring device is pushing a video in the pushed video stream list, the user terminal may directly access the video through the playing information of the video sent by the device management server, and the monitoring device does not need to repeatedly push the video to the streaming media server, so that the burden of the streaming media server is reduced, and the efficiency of obtaining the video is improved.
In step S103, when it is detected that the monitoring device is not pushing a video, the video request instruction is forwarded to the monitoring device, so that the monitoring device pushes the video to a target streaming media server, obtains playing information of the video, and forwards the playing information to the user terminal.
In one embodiment, the playback information includes a playback address and an access method of the video.
In this embodiment, when the device management server does not find in the push video stream list that the monitoring device corresponding to the video request instruction is pushing video, adding the monitoring equipment in the pushed video stream list, increasing the number of pushed video main/sub code streams of the monitoring equipment, selecting a target streaming media server by an equipment management server, taking the target streaming media server as a video release server, sending a video request instruction to the monitoring equipment by the equipment management server, and specifying a video playing address, and the monitoring equipment pushes the video to the target streaming media server, after the video is successfully pushed, the playing information of the video is returned to the equipment management server, the equipment management server forwards the playing information to the user terminal, and the user terminal requests the target streaming media server to play the video according to the playing information.
The embodiment of the invention detects the push state of the corresponding monitoring equipment by acquiring the video request instruction sent by the user terminal; when the monitoring equipment is detected to be pushing videos, sending playing information of the videos to the user terminal; when the monitoring equipment is detected not to push the video, the video request instruction is forwarded to the monitoring equipment, so that the monitoring equipment pushes the video to a target streaming media server, and then playing information of the video is acquired and forwarded to the user terminal. The embodiment of the invention adopts the equipment management server to realize the management of the user terminal and the monitoring equipment, adopts the streaming media server to realize the forwarding of the video, and reduces the workload of the streaming media server, thereby improving the speed and the quality of video playing.
