Embodiment
By describing technology contents of the present invention in detail, realized object and effect, accompanying drawing is coordinated to be explained below in conjunction with execution mode.
The design of most critical of the present invention is: compare to video at video archive server, find out similar video, only retain several versions of the different resolution of same video, and clear up other versions to reduce committed memory, and by the Hash Hash record of video file in file Hash record sheet.Just upload if the Hash hash of the video file that user uploads is not present in the file Hash record sheet in video archive server.
Embodiment one
Please refer to Fig. 1, the embodiment of the present invention one provides a kind of server video management method, comprising:
S1: the Hash hash of all video files on generation server, and by all Hash Hash record to file Hash record sheet;
S2: the Hash hash obtaining new uploaded videos file;
S3: judge whether the Hash hash of new uploaded videos file is present in Hash record sheet,
If so, then step S4 is performed: do not preserve new uploaded videos file,
If not, then step S5 is performed: preserve new uploaded videos file.
The present embodiment is by comparing the Hash Hash record table of video existing on the Hash hash of new uploaded videos and server, if new Hash hash has been present in Hash record sheet, then represent video file existing identical on server, prompting user no longer preserves this video file and takies server memory to reduce.
Embodiment two
The embodiment of the present invention two adds the step of clearing server similar video file on the basis of embodiment one.Videos all in server are compared between two, determine whether that, into same video, concrete grammar is:
To decode the raw frames of the first video and the second video, obtain the first material and the second material;
From the first frame, compare the first material and the second material frame by frame, obtain similar frame;
If all frames are similar frame, then according to similar frame, determine that the first video and the second video are same video.
And when the generation of material, the embodiment of the present invention one can scan the first video and the second video on video archive server; To decode the raw frames of the first video and the second video, generate bitmap frame by frame; According to bitmap, obtain the first material and the second material.
Bitmap is each pixel its color of numeric representation by picture codec.The video pictures of compression itself likely stores by vector or other modes, convert bitmap to and this method can be adopted to compare.
After generation bitmap, the embodiment of the present invention one is further to be obtained,
Reduce the screen resolution of the first material and the second material; Normally resolution is reduced to 1/4;
The RGB component value of pixel in comparison first material and the second material frame of video one by one;
Judge in component value, whether maximum tolerance is less than predetermined tolerance, described predetermined tolerance is such as 10.Concrete, if the value of (R, G, B) three colors respectively comparison be respectively (10,10,10) and (12,8,13), the tolerance of R, G, B is respectively 2,2,3, then getting wherein maximum difference 3 is maximum tolerance.
If maximum tolerance is less than predetermined tolerance, then think pixel color similarity;
Otherwise, then think that pixel color is dissimilar;
Obtain the total number of pixel of color similarity, judge whether the ratio that the total number of the pixel of described color similarity accounts for all pixels is greater than predetermined ratio value, such as 90%;
If so, then confirm that the frame of video of comparison is similar frame;
Otherwise, then confirm that the frame of video of comparison is not similar frame.
According to similar frame, determine that the first video and the second video are that the step of same video is specially:
Comparison first video and the second video one by one from the first frame;
If there is dissimilar frame, then think that the first video and the second video are different video;
If all frames are similar frame, then think that the first video and the second video are same video.
In practical operation, likely occur that the resolution of two videos is different, should come relatively can avoid some special circumstances with a low point resolution: the aberration that such as video occurs after being compressed into little resolution, more just has comparatively big error with high-resolution.Video also likely repeatedly compression be compressed to low resolution and change into high-resolution again, actual color have lost.Resolution is reduced to 1/4 this numeral and can revises, and can adjust according to actual conditions, as 1/2,1/8 etc.Particularly, when comparing the video of 1920x1080 and the video of 1280x720, resolution be reduced to the resolution all lower than these two numerical value and compare, the error brought due to video compression could be reduced like this.The video erection of 1920x1080 is h.265 lossy compression method form instead of former video, color relation wherein can supplement with difference arithmetic, supplementary meeting like this causes error when comparison very large, reduces resolution and can reduce such error, get rid of mathematic interpolation pixel out.Should be understood that, except reducing resolution, can also have other modes, whether the pixel as compared two frames mates completely.But this mode, the frame for video compression compares and is difficult to mate completely.
For all similar videos, divide into groups by resolution, such as be divided into and be greater than 1280x1080, be less than 1280x1080 and be greater than 1024x720 and be less than 10,24x,720 tri-groups, determine often to organize the maximum video of intermediate-resolution, preserve after being labeled as super clear, high definition, SD respectively, remaining video is then deleted.
The method that the present embodiment is divided into groups by video comparison and resolution, only remains the different editions of same video, and deletes all the other videos, carried out effective cleaning to server memory.
