Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, will play or the content of in progress video file is taken a sample according to the order of sequence and presented to the user current, the user can browse, experience video content in advance.
Fig. 1 shows the realization flow of the player method of the video file that the embodiment of the invention provides, and details are as follows:
In step S101, extract a plurality of frame of video in the video file, generate a plurality of thumbnails.
As one embodiment of the present of invention, extract all I frames in the video file, generate the thumbnail of whole I frames.Detailed process is described below: create a thread, this thread is responsible for each video file of decoded video successively, and all I frame in extraction this document, and the thumbnail of whole I frames that will generate preserves, the thumbnail that each video file generates is saved in the corresponding file.Adopt this method promptly to need only this video file file of existence at broadcast state down-sampling video file, the user can check the thumbnail of this video file immediately, and chooses the frame of video in a certain moment to begin to play; It is not obvious but if the scene of this video file is switched, promptly this video file may have only limited a few frame I frames or have only a frame (extreme case: video file has only a picture), then thumbnail shows and presents to several frames of having only of user, does not reach the effect of experiencing video content in advance.
As an alternative embodiment of the invention, a plurality of frame of video by in the sampling time extraction video file generate a plurality of thumbnails.Detailed process is described below:
Create a thread, in certain video process of broadcast, this thread extracts sample frame by the sampling time (for example per 5 minutes once sampling), and the thumbnail of the sample frame extracted is preserved, and the thumbnail that each video file generates is saved in the corresponding file.Adopt the frame of video of this method sampling more complete, guaranteed the integrality of this video file thumbnail, must play once, could generate required thumbnail but prerequisite is this video file.
In actual applications, the I frame in the significant degree selective extraction video file that can switch in conjunction with the scene of video file generates the method for thumbnail or selects and extracts the method that frame of video in the video file generates thumbnail by the sampling time.
In step S102, preserve described a plurality of thumbnail.
As an alternative embodiment of the invention, a plurality of thumbnails that generated by frame of video are preserved, in embodiments of the present invention, the thumbnail that each video file generates is saved in the corresponding file.
In step S103, show described a plurality of thumbnail.As one embodiment of the present of invention, at the file management layer, the user chooses a video file, then can check the thumbnail of this video file.As a preferred embodiment of the present invention, before showing thumbnail, frame of video to a plurality of thumbnail correspondences is arranged in a certain order, be spliced into a new animation streams, such as show about the plane, the plane shows up and down or pass through three-dimensional display, and be shown to the user according to the progressive transparent mode of level, about the user (or up and down or front and back) when sliding this video file thumbnail, the frame of video of a plurality of thumbnail correspondences is rolled according to predefined arrangement mode and is formed the animation switch forms.
In step S104, receive user's selection instruction, begin playing video file from the time point of the frame of video of user-selected thumbnail correspondence.
As one embodiment of the present of invention, but the thumbnail of this video file of user's preview some, selected the frame of video of the crucial thumbnail correspondence liked until the user, when certain thumbnail of preview, the user double-clicks this thumbnail, represent that then the user has chosen this thumbnail, the user can begin to watch this video file from the time point of the pairing frame of video of current thumbnail.
One of ordinary skill in the art will appreciate that, realize that all or part of step in the foregoing description method is to instruct relevant hardware to finish by program, described program can be in being stored in a computer read/write memory medium, described storage medium is as ROM/RAM, disk, CD etc.
Fig. 2 shows the structure of the portable terminal that the embodiment of the invention provides, and for convenience of explanation, only shows the relevant part of the embodiment of the invention.Wherein, the Play System of video file can be the software unit that is built in portable terminal, the unit of hardware cell or soft or hard combination.
The Play System of this video file comprises: thumbnail generation unit 21, thumbnail storage unit 22, thumbnail display setting unit 23, thumbnail display unit 24, presentation of video frames unit 25.
Wherein thumbnail generation unit 21 is used for extracting a plurality of frame of video of video file, generates a plurality of thumbnails, and thumbnail generation unit 21 comprises I frame thumbnail generation unit 211 or sampling time frame of video thumbnail generation unit 212 in embodiments of the present invention.
I frame thumbnail generation unit 211 is used for extracting all I frames of video file, generate the thumbnail of whole I frames, adopt this method need not be at broadcast state down-sampling video file, promptly as long as there is this video file file, the user can check the thumbnail of this video file immediately, and chooses the frame of video in a certain moment to begin to play; It is not obvious but if the scene of this video file is switched, promptly this video file may have only limited a few frame I frames or have only a frame (extreme case: video file has only a picture), then thumbnail shows and presents to several frames of having only of user, does not reach the effect of experiencing video content in advance.
Sampling time frame of video thumbnail generation unit 212 is used for extracting by the sampling time a plurality of frame of video of video file, generate a plurality of thumbnails, adopt the frame of video of this method sampling more complete, guaranteed the integrality of this video file thumbnail, but prerequisite is this video file must be play once, could generate required thumbnail.
In actual applications, can select I frame thumbnail generation unit 211 or sampling time frame of video thumbnail generation unit 212 to generate the thumbnail of video file in conjunction with the significant degree that the scene of video file is switched.
Thumbnail display setting unit 23, be used to set the arrangement mode and the display mode of the frame of video of described a plurality of thumbnail correspondences, the arrangement mode of the frame of video of described a plurality of thumbnail correspondences is set at animated, the display mode of the frame of video of described a plurality of thumbnail correspondences is set to arrange by the progressive transparent mode of level shows, concrete condition does not repeat them here as mentioned above.
Presentation of video frames unit 25 is used to receive user's selection instruction, begins playing video file from the time point of the frame of video of user-selected thumbnail correspondence, and concrete condition does not repeat them here as mentioned above.
In embodiments of the present invention, will play or the content of in progress video file is taken a sample according to the order of sequence and presented to the user current, the user can browse, experience video content in advance; Before frame of display video, carry out certain display setting, make things convenient for the user to browse, operate; In addition, the user also can be according to the hobby of oneself, selects a frame from frame of video, begins to watch video content from the time point of this frame, makes the user more convenient to operate.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
