Embodiment 1

[0059] figure 1 A flowchart showing a video generation method according to an embodiment of the present disclosure. Such as figure 1 As shown, the video generation method includes:

[0060] In step S11 , during the live broadcast of the live video, the currently live video segment and the identifier of the currently live video segment of the live video are acquired.

[0061] In this embodiment, in the process of live video broadcasting, the currently live video segment and the identifier of the currently live video segment can be continuously acquired, so that multiple video segments and each video segment of the live video can be obtained logo.

[0062] Wherein, the identification of the video segment may be an ID (Identification, identification number) of the video segment, which is not limited here.

[0063] In step S12, according to the identification of the currently live video segment and the identification of the live video segment, a latest on-demand segment identi...

[0109] Figure 4 A block diagram of a video generating device according to an embodiment of the present disclosure is shown. Such as Figure 4 As shown, the device includes: a first acquisition module 41, used to acquire the current live video segment of the live video and the identifier of the currently live video segment during the live video live broadcast; the first generation module 42, It is used to generate the latest on-demand segment identification set corresponding to the live video according to the identification of the currently live video segment and the identification of the live broadcast completed video segment; the determination module 43 is used to determine when the currently live video segment is the In the case of the last video segment of the live video, the latest on-demand segment identification set is used as the on-demand video identification set corresponding to the live video; the second generation module 44 is used to use each of the corresponding...

Embodiment 3

[0117] Figure 6 is a block diagram of an apparatus 800 for video generation according to an exemplary embodiment. For example, the apparatus 800 may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, and the like.

[0118] refer to Figure 6 , the apparatus 800 may include one or more of the following components: a processing component 802, a memory 804, a power supply component 806, a multimedia component 808, an audio component 810, an input / output (I / O) interface 812, a sensor component 814, and a communication component 816.

[0119] The processing component 802 generally controls the overall operations of the device 800, such as those associated with display, telephone calls, data communications, camera operations, and recording operations. The processing component 802 may include one or more processors 820 to execute instructions to complet...

Abstract

The invention relates to a video generation method and a video generation device. The video generation method includes acquiring a current live video clip of a live video and current live video clip identification in a live video broadcast process; generating a newest video-on-demand clip identification set corresponding to the live video according to the current live video clip identification and identification of video clips completed in live broadcast; in case that the current live video clip is the last video clip of the live video, taking the newest video-on-demand clip identification set as a video-on-demand clip identification set of the live video; splicing all the video clips corresponding to the video-on-demand clip identification set to generate a first video-on-demand video. The video generation method and the video generation device have the advantages that the video-on-demand video corresponding to the live video can be released quickly, so that delay of releasing the video-on-demand video corresponding to the live video is shortened greatly, and persistent storage of the video-on-demand video corresponding to the live video can be achieved.

Description

technical field [0001] The present disclosure relates to the field of multimedia technologies, and in particular to a video generation method and device. Background technique [0002] The live video may include live TV programs and web live video, etc. After the live video broadcast is over, the operator of the video website usually uploads, transcodes, reviews and releases the complete live video to convert the live video into an on-demand video. If the live video takes a long time, the user needs to wait for a long time to see the on-demand video corresponding to the live video on the video website after the live broadcast ends. For example, it takes about an hour to upload, transcode, review, and publish a 90-minute live video. Therefore, for the 90-minute live video, if the live broadcast ends at 00:00, the user can only see the relevant on-demand video at about 01:00, and the delay is relatively large. Contents of the invention [0003] In view of this, the present...
