In embodiment of the present invention, a kind of method of being replaced video and realized rapid preview by picture is proposed, can realize mouse by picture and arrive aobvious effect, can realize rapidly the demonstration for preview content.
Fig. 1 is the progress method for previewing flow chart according to the video player of embodiment of the present invention.
As shown in Figure 1, the method comprises:
Step 101: according to the video time section setting in advance, video content is divided, and respectively the video content in video time section is carried out to sectional drawing.
In video server, conventionally preserve a large amount of video files, can in video server, divide the particular content of video file according to the video time section setting in advance, and respectively the video content in video time section be carried out to sectional drawing.
Because the progress bar length of video player is normally fixing, progress bar length that therefore can be based on video player and the reproduction time of video file arrange corresponding relation, more respectively the video content in video time section are carried out to sectional drawing.Such as: player progress bar length is fixed, can the time corresponding sectional drawing is corresponding with video duration.If video duration is shorter, the unit that user can traveling time is just less, needs time shorten corresponding sectional drawing, so just can preview arrive more detailed pictorial information.Otherwise, if video time is longer, can be by longer the time corresponding sectional drawing.
Illustrating, can be 1 minute following video by video duration, is set to every one of 1 second sectional drawing; For the video of 1 to 5 minute, be set to every one of 2 seconds sectional drawing; For the video of 5 to 10 minutes, be set to every one of 5 seconds sectional drawing; For 10 minutes above videos, be set to every one of 10 seconds sectional drawing.
Although describe above the relative set for sectional drawing duration in detail, it will be appreciated by those of skill in the art that this set is only exemplary, and be not used in embodiment of the present invention is limited.
In one embodiment, can divide video file according to the time span of decile, and respectively the video content in the time span video time section of each decile be carried out to sectional drawing.Alternatively, can be also according to the fixing sectional drawing time setting in advance, the video content of video file is carried out to sectional drawing.
Preferably, for the video content in each decile time span video time section, can intercept multiple sub-sectional drawings according to the playing sequence in this video time section respectively, and each sub-sectional drawing is combined as to the sectional drawing collection corresponding to these point of time span video time section by playing sequence.Wherein, every sub-sectional drawing is all the complete sectional drawing for video content.Wherein, intercepting according to the playing sequence in video time section in the process of sub-sectional drawing, preferably intercept at least two sub-sectional drawings.It will be appreciated by those of skill in the art that embodiment of the present invention also can only intercept a sub-sectional drawing, sectional drawing is concentrated and is only had a sub-sectional drawing.
Such as, can be according to taking advantage of many picture compound modes that multiple sub-sectional drawings are set in a large picture file more, this large picture file is the sectional drawing collection of these point of time span video time section.Take advantage of many picture compound modes can conveniently navigate to the sub-sectional drawing that sectional drawing is concentrated more.
In fact, the compound mode of sub-sectional drawing can not be also to take advantage of many compound modes more, and sub-sectional drawing can not limit at the concentrated position disposing way of sectional drawing.
