Video preview method, device and electronic equipment

Abstract

The embodiment of the invention provides a video preview method, a device and electronic equipment. The method comprises the steps that an on-demand request sent for a target monitoring video is received, a video index corresponding to video data is generated for each piece of video data in the target monitoring video in advance, and the video index is used for representing the shooting time of the corresponding video data; collecting a video index corresponding to each piece of video data in the target monitoring video; determining a target time period in which the target event is expected to occur; determining a video index of which the represented shooting time belongs to the target time period from all the obtained video indexes, and taking the video index as a target video index; according to the target video index, obtaining video data corresponding to the target video index as target video data; and extracting a preview picture from the target video data and displaying the preview picture. System resources consumed by video preview can be effectively reduced.

Description

Technical field [0001] The present invention relates to the field of streaming video technologies, and more particularly to a video preview method, apparatus, and electronic device. Background technique [0002] In some application scenarios, users may only want to watch specific clips in the video, for example, users who may only want to watch a plot-related fragment when viewing film and television works. To view the fragment, users need to quickly view video content through fast forward and / or fast retreat, thereby positioning the fragment you want to watch in the video, and the operation is more cumbersome. [0003] In the relevant technique, to help users quickly locate the clips you want to watch, you can provide users with video previews, exemplary, exemplary, exemplary, can be a critical video frame in a video frame in a video. , Extract the thumbnail of the key video frame as a preview. When the user faster and / or quickly retreats, according to the timestamp of the c...

Problems solved by technology

[0004] However, in the security field, because the surveillance video captured is often a video of a long period of time, for example, it may be a video within a day or even a few days, and users often have a clear purpose when viewing the surveillance video, so the user They are often only interested in video clips within a short period of time. If a thumbnail is generated by selecting a key video frame at a preset interval, a large number of preview images need to be generated for the surveillance video, and most preview images cannot help User locates snippets of interest

However, generating and storing the preview image needs to consume certain system resources, so this solution will lead to a serious waste of system resources
