See the description above for step S12 for step S22.
In step S23, when the currently live video segment is the last video segment of the live video, the latest on-demand segment identifier set is used as the on-demand video identifier set corresponding to the live video.
See the description above for step S13 for step S23.
In step S24, the video segments corresponding to the on-demand video identifier set are spliced to generate a first on-demand video.
See the description above for step S14 for step S24.
In step S25, verification information corresponding to the on-demand video identifier set is generated.
The verification information corresponding to the on-demand video identification set may be generated by using MD5(Message Digest Algorithm, fifth edition). The verification information may be MD5 information forged against the on-demand video identification set, and is not limited herein.
In step S26, the verification information is associated with the first video on demand.
Wherein the verification information may be used to uniquely identify the first video on demand.
In a possible implementation manner, the video definitions of the video segments corresponding to the latest on-demand segment identifier set are all first definitions, and the first on-demand video is an on-demand video with the first definition corresponding to the live video. In this implementation manner, the video definitions of the video segments corresponding to the latest on-demand segment identifier set are the same and are all the first definition. And the latest on-demand segment identification set generated according to the identification of each video segment with the first definition is the latest on-demand segment identification set with the first definition.

For example, the first definition may be a standard definition, and is not limited herein.
In step S32, a latest on-demand segment identifier set of the first definition corresponding to the live video is generated according to the identifier of the currently live video segment of the first definition and the identifier of the video segment of the first definition that is completed in the live video.
In this example, a corresponding latest on-demand segment identification set is generated according to the identifications of the currently live video segment and the live video segment with the same definition. For example, a latest on-demand segment identifier set of the first definition corresponding to the live video may be generated according to the identifier of the currently live video segment of the first definition and the identifier of the video segment of the first definition that is completed in the live broadcast.
In this example, each of the identifiers in the latest on-demand segment identifier set of the first definition corresponds to a video segment of the first definition. According to the mark in the latest on-demand segment mark set with the first definition, the corresponding video segment with the first definition can be found.
In step S33, when the current live video segment with the first definition is the last video segment with the first definition of the live video, the latest on-demand segment identifier set with the first definition is used as the on-demand video identifier set with the first definition corresponding to the live video.
And in the case that the current live video clip with the first definition is the last video clip with the first definition of the live video, the identification of all the video clips with the first definition of the live video and all the video clips with the first definition are indicated. Therefore, under the condition that the current live video segment with the first definition is the last video segment with the first definition of the live video, the latest on-demand segment identification set with the first definition can be determined as the on-demand video identification set with the first definition corresponding to the live video. That is, the first definition on-demand video identification set includes identifications of all video segments of the first definition.
In step S34, the video segments corresponding to the on-demand video identifier set with the first definition are spliced to generate a first on-demand video, where the first on-demand video is an on-demand video with the first definition corresponding to the live video.
In this example, the video segments corresponding to the first definition on-demand video identifier set may be physically spliced to generate a first on-demand video. The first click video may be for persistent storage.
In step S35, verification information corresponding to the first definition on-demand video identifier set is generated.
The MD5 may be used to generate verification information corresponding to the first definition on-demand video identifier set. The verification information may be MD5 information forged for the first definition on-demand video identification set, which is not limited herein.
In step S36, the verification information is associated with the first video on demand.
And according to the verification information corresponding to the on-demand video identification set with the first definition, an on-demand video identification packet corresponding to the on-demand video identification set with the first definition can be generated. The check information can be used for uniquely determining the on-demand video identification packet corresponding to the on-demand video identification set with the first definition.
In step S37, in the case that there is an on-demand video with other definition corresponding to the live video, the first on-demand video is associated with the on-demand video with other definition to obtain an on-demand video set corresponding to the live video.
As an example of this embodiment, a source file of a live video includes a first definition, a second definition, and a third definition. For example, the first definition may be standard definition, the second definition may be high definition, and the third definition may be super definition, which is not limited herein. Three processing tasks may be generated for stitching the identifications of the video segments of the first definition, the second definition, and the third definition, respectively. For example, the live video includes 5 video segments of a first definition, 5 video segments of a second definition, and 5 video segments of a third definition. The identifiers of the 5 first definition video segments are respectively FilID 01, FilID 02, FilID 03, FilID 04 and FilID 05, the identifiers of the 5 second definition video segments are respectively FilID 001, FilID 002, FilID 003, FilID 004 and FilID 005, and the identifiers of the 5 third definition video segments are respectively FilID 0001, FilID 0002, FilID 0003, FilID 0004 and FilID 0005. According to the identifiers of the 5 video segments with the first definition, an on-demand video identifier set with the first definition can be generated; according to the identifiers of the 5 video segments with the second definition, an on-demand video identifier set with the second definition can be generated; from the identifications of the 5 third definition video segments, a third definition on-demand video identification set may be generated. The verification information MD 51 corresponding to the on-demand video identifier set with the first definition, the verification information MD 52 corresponding to the on-demand video identifier set with the second definition, and the verification information MD 53 corresponding to the on-demand video identifier set with the third definition may be generated. According to the verification information MD 51 corresponding to the on-demand video identification set with the first definition, an on-demand video identification packet (mediaID 1) corresponding to the on-demand video identification set with the first definition can be generated; according to the verification information MD 52 corresponding to the on-demand video identification set with the second definition, an on-demand video identification packet (mediaID 2) corresponding to the on-demand video identification set with the second definition can be generated; and generating an on-demand video identification packet (MediaID 3) corresponding to the on-demand video identification set with the third definition according to the verification information MD 53 corresponding to the on-demand video identification set with the third definition. According to the 5 video segments with the first definition, a first on-demand video, namely an on-demand video with the first definition, can be generated; according to the 5 video segments with the second definition, a second video-on-demand can be generated, namely the video-on-demand with the second definition; from the 5 third definition video segments, a third video on demand, i.e., a third definition video on demand, may be generated. And associating the first on-demand video, the second on-demand video and the third on-demand video to obtain an on-demand video set corresponding to the live video.
In step S38, an upload voucher corresponding to the on-demand video set is obtained.
Wherein an upload token (upload token) may be used for transcoding.
In step S39, a target video corresponding to the on-demand video set is generated according to the upload voucher.
The target video can be a complete on-demand video corresponding to the live video. By generating the target video, the persistent storage of the complete on-demand video corresponding to the live video can be realized, the corresponding complete on-demand video is obtained without manually recording the live video again, and the recording cost and the labor cost for generating the complete on-demand video can be reduced.
