Optionally, in this embodiment, the video server may further receive a second file identifier transmitted by the merge server while receiving the second multimedia file transmitted by the merge server, and record a replacement relationship of the file identifier while replacing the multimedia file. So that the user can watch the latest version of the on-demand content when the user requests the multimedia file.

In an alternative embodiment, as shown in fig. 5, the merge server is used to transcode the live stream to obtain the multimedia file for on-demand. A first client (e.g., a cloud clipping system) may initiate a live merge process to a merge server. In the live broadcast merging process, the merging server supports the pre-downloading logic, and live broadcast contents are cached locally in the merging server, so that the time consumption of downloading can be eliminated. And the merging process supports a content adding function for many times, and ensures that operations such as editing, adding additional content and the like can be modified after the video content is released to the external network. The cloud clipping system provides operation addition operation, the merging server generates a unique VID for each merged video, and the video files are locally cached, and the video files can comprise a plurality of definition files. After receiving a video addition request reported by the cloud clipping system, the merging server acquires ts files (i.e., the second multimedia resources) of the added segments from the pre-download cache, and merges the ts files into final video files (i.e., the second multimedia files) by combining with the video files (i.e., the first multimedia files) generated last time by the local cache. And the newly generated video file generates a new VID, records the LINK to the most original video VID which is sent quickly, and reports the LINK to the video server. The merge server stores the newly generated video file.

For example: the file identification of the multi-definition video which is originally rapidly released is VID, a new file identification is allocated to the multi-definition video as VID _1 after ADD _1 is appended to the multi-definition video by a content appending request for the first time, VID _2 is allocated to the multi-definition video after ADD _2 is appended to the multi-definition video by a content appending request for the second time, VID _2 is allocated to the multi-definition video by a content appending request for the third time, ADD _3 is allocated to the multi-definition video as VID _3 after ADD _2 is appended to the multi-definition video for the third time, and the new file identification is allocated to the multi-definition video as VID _ n after ADD _ n-1 is appended to the content appending request for the nth time, and the new file. Finally, the file identifier corresponding to the playing link VID is VID _ n.

s804, receiving a playing instruction sent by a playing server, wherein the playing instruction is used for instructing to play a second multimedia file, the first multimedia file comprises a stored first multimedia resource in a live stream being played, and the second multimedia file comprises the first multimedia resource and a second multimedia resource;

s806, responding to the playing indication, playing the second multimedia file.

Optionally, in this embodiment, the second client may be, but is not limited to, a client for playing a live video stream or an on-demand video file. Such as: a live client, a multimedia client, a browser client, and the like. The user can click the video link on the second client to obtain the address of the video resource, and then call the video resource to the address to play.

Optionally, in this embodiment, the user clicks the play link corresponding to the first multimedia file on the second client, the second client responds to the click operation of the user to request the play server for the multimedia file of the play link, and plays the second multimedia file currently corresponding to the play link according to the play instruction sent by the play server. Thereby enabling the user to view the newly released on-demand content.

As an optional scheme, the playing instruction further carries a replacement instruction, where the replacement instruction is used to indicate that the multimedia file corresponding to the playing link is replaced, and playing the second multimedia file in response to the playing instruction includes:

s1, responding to the playing instruction, playing the second multimedia file, responding to the replacing instruction, and sending a timing query request to the playing server at a timing, wherein the timing query request is used for querying whether the multimedia file corresponding to the playing link is replaced;

s5, the third multimedia file is played from the second playing point.

Optionally, in this embodiment, the second client may further periodically query, according to an instruction of the replacement instruction sent by the play server, whether a play link corresponding to the currently played second multimedia file is updated, and when it is detected that the second multimedia file is updated to the third multimedia file, start to play the third multimedia file at a second time point corresponding to the third multimedia file from the first time point of the current play, so that the update of the multimedia file is not sensible to the user, and the user experience is improved.

In an alternative embodiment, as shown in fig. 9, for the first time the user enters the playback, the latest full playback address (which may be the original multimedia file or the latest replacement multimedia file) is accessed. However, for a user in the playing process, after the replacement occurs, the user side plays a video with an old CDN address, and the content and duration of the video are all old versions, and the content and duration of the playing are not consistent with those of a user who is playing newly, which may result in a discount on the experience of the user. In contrast, when the replacement occurs, the playing service may notify the user client of the content updating time length and the CDN playing address, and after receiving the playing service updating notification, the client performs playing switching and updates the playing time axis time length according to the current point location of the user playing, so as to ensure that the latest content is played by the user. When the playing service returns a playing link to the client, the client is provided with the replacement identifier and provides the query capability; the client regularly inquires the playing service according to the replacement identifier and checks whether the playing LINK generates the latest LINK replacement; when the client inquires that the VID generates replacement, the client requests the playing service for the latest CDN playing address of the VID again; the client downloads the latest video file again according to the returned latest CDN playing address; and searching the current playing time point position of the user, switching the playing picture, and updating the playing time axis duration.
