s3, judging whether the stream media is received: since the code stream and the resolution factor have the greatest influence on IO, whether the existing streaming media can process the video or not is deduced according to the code stream:
s31, if it can not receive, discarding proves that the cluster of the streaming media has reached the peak value of processing the video, the current streaming media is not enough to support the video, if the stream is still received, the node of the streaming media is very easy to be down, thus refusing to receive;
s32: if the data can be received, the load is balanced, the streaming media nodes are distributed, and the streaming media processes the received data.

as shown in fig. 1, the present invention provides a distributed access method for a video networking platform, which can improve the reliability and availability of the video networking platform, improve the platform load balancing capability, and support horizontal extension. The national standard video networking platform can be effectively managed when thousands of videos are accessed.
Fig. 1 shows a basic flow chart of a video networking platform. Firstly, the front-end equipment performs sip registration, after the registration is successful, the video networking platform queries the resolution and the code stream of the front-end equipment and stores the two attributes and the equipment id into the zookeeper, and because the code stream and the resolution which have the greatest influence on IO are the code stream and the resolution, whether the existing streaming media can process the video or not is deduced according to the code stream, and if the existing streaming media cannot process the video, the video is discarded. Discarding proves that the streaming media cluster has reached the peak value of processing video, and if the stream is still received, the streaming media node is very likely to be down.
The distributed access method of the video networking platform is applied to a GB28181 national standard platform, wherein the GB28181 national standard platform comprises front-end equipment, a sip server and a streaming media server, and the method comprises the following steps:
s1, real-time video stream enters the front-end equipment and sip registration is carried out;
s2, after the registration is successful, the video networking platform inquires the resolution and the code stream of the video networking platform and stores the two attributes and the equipment id into the zookeeper;
s3, judging whether the stream media is received: since the code stream and the resolution factor have the greatest influence on IO, whether the existing streaming media can process the video or not is deduced according to the code stream:
s31, if it can not receive, discarding proves that the cluster of the streaming media has reached the peak value of processing the video, the current streaming media is not enough to support the video, if the stream is still received, the node of the streaming media is very easy to be down, thus refusing to receive;
s32: if the data can be received, the load is balanced, the streaming media nodes are distributed, and the streaming media processes the received data.
Preferably, in step S1, the GB 28181-based national standard platform includes a front-end device, a sip server and a streaming server, where:
the front-end equipment is used for monitoring the video acquisition, coding, storage and transmission functions of a site;
sip server, which provides registration, and establishes/terminates session connection function, and performs session control;
the streaming media server provides a forwarding service of real-time media stream, and provides storage of media, retrieval of historical media information and on-demand service.
Preferably, in step S2, the GB 28181-based national standard platform refers to a distributed architecture based on a GB28181 video networking platform, where: the zookeeper cluster is used for monitoring the change of streaming media nodes and storing relevant parameters of front-end equipment by using distributed coordination service.
Preferably, in step S2, zk is a zookeeper node, a plurality of zks form a zookeeper cluster, and a plurality of streaming media service nodes form a streaming media cluster.
Preferably, in step S2, the zookeeper node directory is stored as { streaming media node } - { device id }.
Preferably, in step S31, when the streaming media server is down and cannot be recovered to normal in a short time, the sip server initiates registration again with the redundant streaming media node according to the device id stored in the zookeeper under the streaming media node, so as to ensure that the multiple channels of videos are not affected.
Preferably, in step S32, because the server difference is small and the front-end device is stored in zookeeper, the number of front-end devices under each streaming media node is counted by using a load balancing policy of the minimum connection number LC.
Preferably, in step S32, the streaming media node where the minimum number of front-end devices is located is selected, and this node is the streaming media node for the next video access.
As shown in fig. 2, the technical solution of the present invention is based on GB28181 video networking platform for distributed processing. And zk is a zookeeper node, and a plurality of zk can form a zookeeper cluster. The plurality of streaming media service nodes form a streaming media cluster.
Fig. 3 shows a redundant backup of a streaming media server of a video networking platform. When one streaming media server is down and cannot be recovered to normal in a short time (zookeeper can automatically perform heartbeat detection), the sip service can re-initiate registration to a redundant streaming media node according to the device id stored on the zookeeper under the streaming media node, so that the influence on multiple paths of videos is avoided. The specific zookeeper node directory may be stored as { streaming media node } - { device id }.
Fig. 4 is a schematic diagram illustrating a streaming media load balancing of a video networking platform. Because the server differences are small and the front-end device will be stored in zookeeper (which will also delete the node if the front-end device is disconnected). Therefore, a load balancing strategy of the minimum connection number LC is adopted, the number of front-end equipment under each streaming media node is counted, and the streaming media node where the minimum number of the front-end equipment is located is selected. The node is the streaming media node for the next video access.
The distributed access method of the video networking platform provided by the invention is used for releasing a new video stream by putting a streaming media server node aiming at the situation that a GB28181 video networking platform cannot effectively utilize the network condition and the code rate and resolution ratio distribution of a camera after reading media data from the camera. And the most adopted codes of the current monitoring video are H264 and H265, although the codes have high coding efficiency and can effectively reduce the network io overhead and the pressure of a streaming media server, how to realize load balance, high reliability and high availability when the monitoring video faces thousands of paths of video monitoring.
The method can be widely applied to the management occasion of the cloud video access process.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
