Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
An existing system for providing a streaming media service generally includes a plurality of streaming media servers, and a third party needs to access ports of different streaming media servers to obtain corresponding video streams, which increases difficulty of obtaining video streams by the third party and also may have a large potential safety hazard. The address of the streaming media server may be changed in some cases, for example, when the streaming media service is upgraded, the address of the streaming media server may be changed, and after the streaming media service is changed, a third party may not access the streaming media service smoothly, and thus the video stream may not be acquired. In addition, when the existing platform for deploying the streaming media service is used for online or offline streaming media service, the development of the manual examination and approval port opening and closing of operation and maintenance personnel is needed, and more labor cost is increased.
The disclosed embodiments provide a video streaming system, a method, a server, a device and a storage medium, which aim to solve at least one of the above technical problems of the prior art.
Fig. 1 shows a schematic architecture diagram of a video streaming system provided by the disclosed embodiment, and as shown in fig. 1, the video streaming system includes a reverse proxy server, at least one forwarding server, and a streaming media server associated with each forwarding server. Wherein each forwarding server can communicate with the reverse proxy server, and the forwarding server can communicate with the associated streaming media server.
The Reverse Proxy server is used for Proxy receiving a connection request on the internet, then forwarding the request to an internal server (such as a forwarding server) on an internal network, and returning a result obtained from the internal server to a client requesting connection on the internet, where the Proxy server is represented as a server to the outside.
Streaming media refers to a form of media that streams audio, video, and multimedia files over a network. Compared with the network playing mode of watching after downloading, the streaming media is typically characterized in that continuous audio and video information is compressed and then put on a streaming media server, and a user can watch while downloading without waiting for the whole file to be downloaded. The streaming media server is a core system of streaming media application and is a key platform for providing video service for users; the main functions of the streaming media server are to collect, cache, schedule, transmit and play streaming media contents. The streaming media server of the embodiment of the present disclosure is mainly used for serving streaming media, which is mainly video streaming, and of course, the streaming media server may also be used for serving other types of streaming media.
The forwarding server may serve as a message forwarding node between the reverse proxy server and the streaming server, and forward a message (e.g., a request) sent by the reverse proxy server to the streaming server, and forward a message (e.g., a video stream) sent by the streaming server to the reverse proxy server.
In the embodiment of the present disclosure, the reverse proxy service may be an nginnx reverse proxy server, and of course, the reverse proxy server in the video streaming system may also be another type of server, which is not limited by the present disclosure. The video streaming system may deploy servers using the kubernets (K8s) architecture, each of which may be considered as a Pod in the kubernets architecture, although the video streaming system may deploy servers using other types of architectures, and the disclosure is not limited thereto.
Alternatively, the video streaming system may be pre-partitioned into multiple namespaces (Name spaces), and each streaming service and its forwarding server may be deployed in a specified namespace. As shown in fig. 1, the video streaming system may pre-partition a namespace a and a namespace B, and the streaming media servers in the same namespace are used for serving video streams in the same scene.
For example, at least one monitoring device is respectively arranged in an area a and an area B to acquire video streams, wherein a streaming media server in a namespace a is used for the video stream acquired by the monitoring device serving the area a, and a streaming media server in a namespace B is used for the video stream acquired by the monitoring device serving the area B. It is understood that video stream 1, video stream 2 and video stream 3 in fig. 1 are all video streams captured by the monitoring devices of area a.
In the embodiment of the disclosure, the reverse proxy server receives an acquisition request for the video stream, and sends the acquisition request to a target forwarding server in the at least one forwarding server. In the embodiment of the present disclosure, the port of the reverse proxy server may be a common port for accessing all streaming media servers in the video streaming system, and the acquisition request for the video stream sent by the third party may be received by the reverse proxy server. For ease of understanding and description, the embodiments of the present disclosure define the forwarding server that needs to receive the acquisition request sent by the reverse proxy server as the target forwarding server.
It is to be appreciated that the acquisition request can indicate a corresponding target forwarding server, and the reverse proxy server can determine the target forwarding server from the at least one forwarding server based on the indication of the acquisition request. Optionally, the obtaining request of the embodiment of the present disclosure includes name information of a forwarding service. Before the reverse proxy server sends the obtaining request to a target forwarding server in the at least one forwarding server, the reverse proxy server may further parse name information from the obtaining request, and determine the target forwarding server from the at least one forwarding server based on the name information.
The target forwarding server may receive the obtaining request sent by the reverse proxy server, and send the obtaining request to a target streaming media server associated with the target forwarding server. The forwarding servers and the streaming media servers deployed in the video streaming transmission system of the embodiment of the disclosure are in one-to-one correspondence, and when the forwarding servers and the streaming media servers are deployed, the association relationship between each forwarding server and the corresponding streaming media server can be established. For ease of understanding and description, embodiments of the present disclosure define a streaming server associated with a target forwarding server as a target streaming server.
And the target streaming media server receives the acquisition request sent by the associated target forwarding server, calls the target video stream indicated by the acquisition request, and returns the target video stream through the target forwarding server and the reverse proxy server. It is to be understood that each streaming server may be configured to serve at least one video stream, and in the embodiment of the present disclosure, the video stream indicated by the retrieval request may be defined as the target video stream. After the target streaming media service calls the target video stream, the target streaming media service can send the target video stream to the target forwarding server, then the target forwarding server sends the target video stream to the reverse proxy server, and the reverse proxy server returns the target video stream to the third party.
It is to be understood that the acquisition request may indicate a corresponding target video stream, and the target streaming media server may invoke the target video stream indicated by the acquisition request based on the indication of the acquisition request. Optionally, the obtaining request of the embodiment of the present disclosure includes address information of one path of video stream. When the streaming media server calls the target video stream indicated by the acquisition request, the streaming media server is specifically configured to: analyzing the address information from the acquisition request, and sending a video stream calling request to the video shooting equipment indicated by the address information; and receiving the target video stream returned by the video shooting device according to the video stream calling request.
As described above, the acquisition request may include name information of the target forwarding server and address information of the target video stream to be acquired. In the embodiment of the present disclosure, after the streaming media server is deployed to the video streaming system, a worker may generate a splicing address for acquiring a video stream for each video stream based on name information of a forwarding server corresponding to the streaming media server, address information of the video stream used by the streaming media server for service, and other necessary information. For example, the splicing address may include an address of the reverse proxy server, a code of a port of the reverse proxy server, name information of a forwarding server corresponding to the streaming server, address information of a video stream served by the streaming server, a name of a namespace to which the streaming server belongs, and the like. The staff member can store the splicing address to a third party, and the third party can send a video stream acquisition request containing the splicing address so as to acquire the corresponding video stream through the video stream transmission system.
For example, taking video stream 1 and the streaming media server for serving video stream 1 in fig. 1 as an example, the corresponding splicing address of video stream 1 may be: http://192.168.1.100:8080/realtime-ServiceA-NameSpaceA/main _ stream/0. flv. Among the above addresses, "192.168.1.100" is an address of the reverse proxy server, "8080" is a code of a port of the reverse proxy server, "name information of a forwarding server corresponding to the" ServiceA "streaming server," main _ stream "is address information of the video stream 1, and" NameSpaceA "is a name of a namespace to which the streaming server belongs. The third party may send a request for acquiring the video stream including the splicing address, so as to acquire the video stream 1 from the service management platform.
In the embodiment of the present disclosure, each streaming server may have a unique tag, and each forwarding server is associated and bound with the unique tag of the corresponding streaming server. In the embodiment of the disclosure, after the streaming media server is deployed to the video streaming system, a unique tag may be generated for the streaming media server, and the unique tag of the streaming media server is associated and bound with a corresponding forwarding server, so that even if the address of the streaming media server changes, the streaming media server can communicate with the forwarding server through the forwarding server.
Optionally, when the target forwarding server sends the obtaining request to the target streaming media server associated with the target forwarding server, the target forwarding server may determine a unique tag associated and bound with the target forwarding server, and send the obtaining request to the target streaming media server corresponding to the unique tag. As described above, the unique tag of each streaming media server is associated with the forwarding server corresponding to the streaming media server. Therefore, the forwarding server service may determine the unique tag bound thereto, thereby determining the target streaming media server corresponding to the unique tag, and then may forward the acquisition request to the target streaming media server.
The reverse proxy servers are deployed in the video streaming transmission system of the embodiment of the disclosure, the corresponding forwarding server is bound to each streaming media server, and the port of the reverse proxy server can be used as a common port for accessing all the streaming media servers, so that a third party can conveniently obtain a plurality of video streams through one port, and the difficulty in obtaining the video streams is reduced; in addition, the request can be forwarded to the corresponding streaming media server through the forwarding server, so that the risk that a third party cannot smoothly access the streaming media server due to address change is avoided.

Specifically, a port of the reverse proxy server may be used as a common port for accessing all streaming media servers in the video streaming system, and an acquisition request sent by a third party for receiving a video stream may be received by the reverse proxy server.
The acquisition request may indicate a corresponding target forwarding server, and the reverse proxy server may determine the target forwarding server from the at least one forwarding server based on the indication of the acquisition request. Optionally, the obtaining request includes name information of a forwarding service. The target forwarding server is determined from the at least one forwarding server based on the name information after the reverse proxy server parses the name information from the get request.
The target forwarding server may receive the obtaining request sent by the reverse proxy server, and send the obtaining request to a target streaming media server associated with the target forwarding server. Optionally, each streaming media server has a unique tag, and each forwarding server is associated and bound with the unique tag of the corresponding streaming media server. In the embodiment of the disclosure, after the streaming media server is deployed to the video streaming system, a unique tag may be generated for the streaming media server, and the unique tag of the streaming media server is associated and bound with a corresponding forwarding server, so that even if the address of the streaming media server changes, the streaming media server can communicate with the forwarding server through the forwarding server. When the target forwarding server sends the obtaining request to the target streaming media server associated with the target forwarding server, the target forwarding server may determine the unique label associated and bound with the target forwarding server, and send the obtaining request to the target streaming media server corresponding to the unique label.
