It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.
In some alternative embodiments, the method further comprises: receiving an actual playing progress sent by the pseudo live video page end and used for pseudo live broadcasting of the video-on-demand stream; according to the actual playing progress and the theoretical playing progress of the pseudo live broadcast aiming at the video-on-demand stream by the pseudo live broadcast management platform, determining correction parameters of the pseudo live broadcast aiming at the video-on-demand stream; and correcting the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast video page end according to the correction parameters, so that the actual playing progress of the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast video page end is consistent with the theoretical playing progress of the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast management platform. By the method, the correction parameters for performing the pseudo live broadcast on the video-on-demand stream can be accurately determined through the actual playing progress and the theoretical playing progress of the pseudo live broadcast on the video-on-demand stream by the pseudo live broadcast management platform. In addition, by correcting the correction parameter, the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast video page end can enable the actual playing progress of the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast video page end to be consistent with the theoretical playing progress of the pseudo live broadcast of the video-on-demand stream in the pseudo live broadcast management platform. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.
In a specific example, when pseudo live broadcast is performed, the pseudo live broadcast video page end can automatically send a playback chat message associated with the pseudo live broadcast. The method can realize that the associated playback chat message is transmitted without affecting the transmission of the chat message by the student in the current live broadcasting room, and the playback chat message is not displayed in the playback generated by the current pseudo live broadcasting. Specifically, when creating the pseudo live broadcast, whether to associate the playback chat message or not can be configured, if the associated playback chat message is selected, when creating, the playback chat message resource is prepared for the pseudo live broadcast, the associated playback chat message is automatically sent at the time of starting the live broadcast, and the sending time point is consistent with the relative time point of playback. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.
In a specific example, as shown in fig. 1B, when a user creates a pseudo live broadcast through a user background service, the user configures whether the pseudo live broadcast needs to be associated with a chat message for playback, performs chat message content resource preparation after clicking on the association, and stores the chat message for playback in NAS (Network Attached Storage: network attached storage). And when the live broadcast starts, the playback chat message is taken out from the NAS, and the playback chat message is sent according to the relative time point of the chat message. The associated playback chat message can be sent without affecting the normal student to send the playback chat message, and the associated playback chat message is not persisted and the refreshed page disappears. When creating a pseudo live, an associated chat may be selected. And in the process of starting live broadcasting, automatically sending the associated playback chat message according to the corresponding time point. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.
According to the pseudo live broadcast method of the online education, according to the pseudo live broadcast starting time of the pseudo live broadcast video of the online education, the pseudo live broadcast video is packaged into an on-demand video stream; receiving a checking operation of an administrator of the pseudo live management platform for playback chat message related options in the pseudo live management platform; responding to the checking operation, and acquiring first playback chat messages of all pseudo live videos in the pseudo live management platform from a playback chat message database in the pseudo live management platform through a playback chat message acquisition interface; querying, by a playback chat message query interface, a second playback chat message corresponding to the pseudo live video encapsulated into the video-on-demand stream from first playback chat messages of all pseudo live videos in the pseudo live management platform; storing the second playback chat message into a network memory, wherein the second playback chat message is a chat message of a live video corresponding to the pseudo live video packaged into the video-on-demand stream; receiving a video playing request aiming at the pseudo live video, which is sent to the pseudo live video management platform by a pseudo live video page end; and feeding back the storage addresses of the video-on-demand stream and the second playback chat message in the network memory to the pseudo live video page end according to the video playing request, so that the pseudo live video page end obtains the second playback chat message from the network memory according to the storage address when pseudo live broadcasting is carried out on the video-on-demand stream, and sends the second playback chat message according to a pseudo live broadcasting time point. Compared with other existing modes, when the pseudo live broadcast is created, the associated option of the playback chat message can be checked, and when the pseudo live broadcast is created, the pseudo live broadcast video page end can send the pseudo live broadcast associated playback chat message, so that the purposes of activating the pseudo live broadcast atmosphere and enhancing the pseudo live broadcast effect are achieved.
