However, after the current network course is finished, the system needs to store a plurality of files such as audio and video of teachers and students and courseware, and the audio and video of teachers and students are stored separately, and according to different devices of the teacher end and the student end, the formats of the stored audios and videos may not be uniform (for example, the videos may be in the formats of FLV or MP 4), when a playback page is displayed for a user, audios and videos of teachers and students and courseware need to be sequentially loaded to the playback page, the playback page mostly does not support direct loading of videos for video files with various formats, and a third-party software (such as FLASH) needs to be relied on to load and play teaching videos. For the acquisition of the audio and video, a CDN edge node is usually used to pull audio and video data, and the upgrade of a cache system such as a CDN may also cause damage to an audio and video file in a transmission process, so that the audio and video cannot be played. In addition, the playback page needs to load multiple files such as audio and video and courseware and the operation of the multiple files is controlled at the back end, the processing logic is complex when a user drags or jumps, and the above various problems can cause the playback page to have slow entering and dragging speed and strong pause feeling, even cause the playback page to be unusable, and the user experience effect is poor.
As shown in fig. 1, according to an aspect of the present invention, a specific embodiment of a streaming media playback server is disclosed, in this embodiment, the server may receive a streaming media playback instruction sent by a client 10, return a streaming media playback address after querying related information of a streaming media file to be played back, return playback page data based on a page generation instruction of the client 10, so that the client 10 forms a playback page, further search for a storage address of the streaming media file and return the playback page to the client 10, so that the client 10 obtains the streaming media file according to the storage address, loads the streaming media file to the playback page, and displays the streaming media file to a user. The streaming media file can be directly loaded on the playback page, the streaming media file which can be directly loaded on the playback page is obtained by setting the playback page and transcoding all files to be played back, so that the whole playback process is not limited by the upgrade of third-party software, the cross-terminal, anytime and anywhere streaming media file playback is realized, the playback logic of the whole playback system is simplified, the streaming media loading speed is increased, the interactive functions of second start, second drag and the like are realized, and the user experience effect is improved.
The streaming media playback server includes an information forwarding module 20, an application processing module 21, a plurality of service processing modules 22, and a database 23. The database 23 stores related information and storage addresses of the streaming media files.
The information forwarding module 20 may receive a streaming media playback instruction sent by the client 10 and transmit the streaming media playback instruction to the application processing module 21. Preferably, the information forwarding module 20 may select a four-layer load balancer, receive a streaming media playback instruction sent by the client 10 through an IP + port, and transmit the streaming media playback instruction to the application processing module 21.
The client 10 may be a display terminal such as a desktop computer, a notebook, a smart phone, and a tablet computer, which can interact with a user.
The application processing module 21 may receive the streaming media playback instruction forwarded by the information forwarding module 20, and authenticate the validity of the streaming media playback instruction. When the streaming media playback instruction is legal, the streaming media playback instruction is output to the plurality of service processing modules 22, when the streaming media playback instruction is illegal, the streaming media playback instruction belongs to illegal access, and an error prompt is directly returned, so that the application processing module 21 can identify the user legality of the client 10, only allows legal playback requests, prevents illegal requests, and protects the user privacy.
Preferably, the Application processing module 21 may select a seven-layer load balancer, where the seven-layer load balancer includes an Application Programming Interface (API) to authenticate whether the streaming media playback instruction is legal.
The service processing modules 22 may receive the legal streaming media playback instruction, search the database 23 for the related information of the streaming media file requested to be played back, return a streaming media playback address when the related information of the streaming media file exists in the database 23, so that the client 10 forms a playback page, further extract a storage address of the corresponding streaming media file from the database 23 and return the storage address to the client 10, so that the client 10 obtains the streaming media file and loads the streaming media file to the playback page.
In a preferred embodiment, after receiving the streaming media playback instruction, the service processing modules 22 first query whether the requested streaming media file exists in the database 23, and if so, return a streaming media playback address; the client 10 sends a page generation instruction to the application processing module 21 based on the received streaming media playback address, the application processing module 21 generates playback page data based on the page generation instruction, so that the client 10 forms a playback page to be displayed to a user, and meanwhile, based on a media loading instruction of the client 10, a storage address of the streaming media file is acquired in the database 23, so that the client 10 further acquires the streaming media file according to the storage address of the streaming media file, loads the streaming media file to the playback page, and displays and provides an interactive function for the user. Preferably, the streaming media file can be acquired from a data storage server such as a cloud storage space or a CDN edge node 40, and a file with a relatively large size such as an audio/video file can be processed and then synchronized to the CDN edge node, so that the pulling speed of the audio/video file during playback is increased, and an effect that a playback page can be instantly opened and loaded is achieved.
In a preferred embodiment, the application processing module 21 receives a page generation instruction of the client 10, generates HTML5 page data and sends the page data back to the client 10, and forms an HTML5 page, and the HTML5 page can support loading of streaming media files in MP4 format and the like, so that the dependency on third-party software can be reduced.
In another embodiment, the application processing module 21 may further be configured to send a status query instruction to each service processing module 22 at regular time, each service processing module 22 sends a reply instruction back to the application processing module 21 according to the received status query instruction, and if one service processing module of the plurality of service processing modules 22 does not send the reply instruction or send an error instruction back within a specified time, the application processing module 21 stops sending the streaming media playback request to the one service processing module. Therefore, when one or more of the service processing modules 22 in the cluster have a fault, the system can automatically detect the fault service processing module 22, and no longer send a playback request to the fault service processing module 22, thereby ensuring the normal operation of the system. Therefore, a service processing module 22 cluster including a plurality of service processing modules 22 can implement dynamic capacity expansion, the application processing module 21 can be disconnected from one or more service processing modules 22 in the cluster, so that a failed service processing module 22 falls from the cluster, and the service processing module 22 is automatically degraded, and meanwhile, the application processing module 21 can also be dynamically accessed into more service processing modules 22, thereby ensuring the number of the service processing modules 22 in the cluster and improving the system processing performance.
In a preferred embodiment, the streaming media file includes an audio/video file, and the plurality of service processing modules 22 query an audio/video storage address of the audio/video file in the database 23 based on an audio/video file request sent by the client 10 and return the audio/video storage address to the client 10, so that the client 10 searches for a corresponding CDN edge node 40 according to the streaming media file storage address, and obtains file data of the audio/video file from the CDN edge node 40. In this embodiment, the CDN edge node 40 synchronizes the audio and video file on the cloud storage server 30, so that the time for acquiring the audio and video file is shorter, and the loading speed of the playback page is increased.
