Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inventor researches and discovers that with the development of cloud computing, the use scale of cloud service is larger and larger, and how to combine traditional private network video monitoring and cloud service together to realize real-time browsing and watching of monitoring videos and historical video query and playing through the cloud service is a problem to be solved urgently. HLS (HTTP Live Streaming) is a HTTP-based Streaming media network Transport protocol, and its working principle is to divide the whole Stream into small HTTP-based TS (Transport Stream) files for downloading and playing. When a streaming media session is started, the client downloads an extended M3U8 playlist file (M3U 8 file for short) containing metadata for finding an available media stream TS file. The object storage is a distributed storage service for storing massive files, and has the advantages of high expansibility, low cost, reliability, safety and the like. Through various modes such as API, SDK and the like, a user can simply and quickly access to object storage, upload, download and manage multi-format files, mass data storage and management are realized, and storage cost is comprehensively optimized.
Aiming at the problems of video monitoring such as storage, live broadcast and on-demand, and combining with an HLS protocol and object storage, the invention provides a method for realizing real-time storage, browsing, watching and playing of a monitoring video through a cloud service by combining with a video monitoring media server and object cloud storage.
Some embodiments of the disclosed live distribution method are first described in conjunction with fig. 1.
Fig. 1 shows a flow diagram of a live distribution method of some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S101 to S106.
In step S101, the camera pushes a transport stream TS file to the first media server.
Those skilled in the art will understand that the camera can be a monitoring camera, a mobile phone camera, or other terminal plug flow device. The camera can send a request for live broadcasting and pushing the audio and video stream to the first media server through the RTMP or RTSP protocol and the load balancing server, and starts to push the audio and video stream to the media server after the request is allowed.
In step S102, the first media server performs a slicing process on the TS file, and stores a play link of the generated TS slice to the database.
Wherein, the first media server can perform TS slicing according to HLS protocol after receiving the stream. The playing link of the TS slice is a hypertext transfer protocol (HTTP) access link of the first media server, and playing can be achieved.
In step S103, the first media server uploads the generated TS slice to the object storage cloud, and modifies a play link of the TS slice that completes uploading into a share link in the object storage cloud in the database.
The first media server may update the upload completion status (i.e., whether the upload is completed) of the TS slice in real time. For the TS slices which are uploaded, playing the shared links corresponding to the TS slices in the object storage cloud; for the uncompleted uploaded TS slices, the playing link is the HTTP access link of the media server where the TS slices are located. And the media server only uploads the TS slices to the object storage cloud server.
In step S104, the player initiates a play request of the TS file to the second media server.
The player may initiate a live viewing request to the second media server through the load balancing server, and the second media server that receives the play request is not necessarily a live source (the first media server) that receives the push stream, and may or may not be the first media server.
In step S105, the second media server obtains the playing link of the TS slice corresponding to the TS file from the database and sends the playing link to the player.
In some embodiments, the second media server obtains the playing link of the TS slice corresponding to the TS file from the database, generates an M3U8 index file using the playing link of the TS slice corresponding to the TS file, and sends the M3U8 index file to the player.
After receiving a playing request, the media server can obtain a media stream which needs to be obtained and is pushed by a camera according to parameters of the requested links, then searches a database to obtain corresponding TS slice file playing links, forms the obtained playing links into an m3u8 index file, then sends the m3u8 file to the player, and after receiving the index file, the player analyzes the m3u8 index file, the index file contains the playing links of the TS slices, and then obtains the TS slices according to the playing links.
In step S106, the player plays the TS file according to the playing link of the TS slice corresponding to the TS file.
Those skilled in the art will appreciate that the player may be embodied as a monitor player, a cell phone player, or the like. The generated play link of the index file may include both the TS slices that are completed by uploading and the TS slices that are not completed by uploading.
And under the condition that the TS slices corresponding to the TS files are uploaded to the object storage cloud, the player acquires the TS slices of the TS files from the object storage cloud for playing according to the shared links of the TS slices corresponding to the TS files in the object storage cloud. That is, if the playing link is a shared link corresponding to the TS slice in the object storage cloud, the TS slice is directly downloaded from the object storage cloud through the shared link for playing.
And under the condition that the TS slices corresponding to the TS files are not uploaded to the object storage cloud, the player acquires the TS slices of the TS files from the first media server for playing according to the HTTP access link of the first media server. That is, if the play link is a media server address indicating that the upload of the TS slice is not completed, the player downloads the TS slice from the media server where the TS slice is located to play.
The embodiment combines a media server and an object cloud storage service in video monitoring, realizes real-time watching and playing of a monitoring video through an HLS protocol and the object cloud storage service, and realizes slicing, storage and playing functions of live monitoring through the media server, a database server and the object storage cloud, thereby realizing multimedia live broadcast distribution. Meanwhile, the method and the device have the advantages of high expansibility, low cost, reliability, safety and the like of object storage and the advantage of strong universality of the HLS protocol, can reduce the cost of the live broadcast distribution process, and improve the reliability, safety, expandability and universality of the live broadcast distribution process.
In addition, in this embodiment, whether the TS slice is uploaded is considered, the database server records the playing link of the TS slice, the media server updates the playing link of the database server in real time according to the uploading completion of the TS, the media server generates the playing index file in real time according to the playing link stored in the database server, and the playing index file is directly played by the player, and the player directly returns the source or pulls the TS slice from the target storage server for playing.

Fig. 2 illustrates a flow diagram of some embodiments in which a camera pushes a TS file to a first media server. As shown in fig. 2, the present embodiment includes steps S2011 to S2013.
In step S2011, the camera initiates a push request of the TS file to the load balancer.
In step S2012, the load balancer distributes the push request to the first media server.
In step S2013, the first media server receives the TS file pushed by the camera.
