Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] refer to figure 1 , which shows a flow chart of a video preview method according to Embodiment 1 of the present invention, and the method may specifically include:

[0043] Step 101 , for each online video, extract key frames from the online video to form video preview content according to the historical data of watching the online video by the user.

[0044] The embodiment of the present invention uses the key frame extraction technology to automatically generate a video preview content, which occupies much less playback resources than the network video itself, so it can achieve smoother playback than the original network video. The key frame described here is the basic unit that forms video, and frame is the still pictur...

Abstract

The invention provides a video previewing method and device. The method includes the steps that for all network videos, key frames are extracted from the network videos according to the history data of the network videos watched by a user to form video previewing content; when the selection operation of the user for the previewing chain in a video player is received or it is judged that the network environment for playing videos meets the preset condition, the video previewing content, required by the user, of the network videos is obtained; the video previewing content is played. By means of the video previewing method and device, the function of previewing the network videos quickly is achieved, and the problem that the network videos cannot be watched when the network environment is poor is solved.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a video preview method and a video preview device. Background technique [0002] When a user watches a video on the Internet, if he does not know the relevant situation of the video, he wants to know the general content of the video in a preview mode, so as to decide whether to continue watching. In this case, users often learn about a video by continuously dragging at will. This kind of dragging is very random. In most cases, the position that the user drags is not necessarily the key part of the entire video. Users can quickly understand the content of the entire video to a limited extent. Therefore, in this case, the user urgently needs a function that automatically generates a movie trailer, and provides the user with a fast movie content preview function. [0003] On the other hand, the Internet advocates the spirit of sharing. In today’s Internet world where variou...
