Fig. 2 is the structural block diagram of present system embodiment two.
Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: comparing out the portion for starting continuous identical content by parsing video frame by frame
Point, it starting and end time will intercept out respectively, Presence of the Moment will be splitted out.
Fig. 1 is please referred to, the embodiment of the present invention one provides a kind of method for handling piece of video cephalic flexure, comprising:
S1: decoding the raw frames of the first video and the second video, obtains the first material and the second material；
S2: since first frame, compare the first material and the second material frame by frame, obtain same number of frames；
S3: continuous same number of frames is intercepted from the first video, the second video, and saves as head video file.
It is different from the prior art, the embodiment of the present invention one obtains corresponding element by the raw frames of decoding different video
Material, and material is compared frame by frame, obtain same number of frames.Same number of frames is intercepted, i.e. acquisition head video file.By the above-mentioned means, this hair
It is bright can be with the Presence of the Moment of the multiple videos of quick obtaining, and be kept separately so as to save server storage and server
Bandwidth.
Wherein, step S2 specifically:
The screen resolution of first material and the second material is reduced to 1/4；
The color tolerance for comparing pixel in the first material and the second material video frame one by one, obtains similar frame；
The continuous similar frame that duration meets preset condition is obtained, as same number of frames.
Wherein, it when obtaining the step of similar frame, can also be operated by following manner:
The RGB component value of pixel in the first material and the second material video frame is compared one by one；
Judge whether maximum tolerance is less than predetermined tolerance in component value；
If so, thinking that pixel color is similar；
It is on the contrary, then it is assumed that pixel color is dissimilar；
The similar pixel total number of color is obtained, determines whether the total number ratio is greater than predetermined ratio value；
If so, the video frame that confirmation compares is similar frame；
Conversely, then confirming that the video frame of comparison is not similar frame.
And when obtaining the step of same number of frames, it can also be carried out by following manner:
The compared pixels point tolerance frame by frame on the first material and the second material obtains continuous similar frame；
Judge whether the duration of continuous similar frame is greater than scheduled duration；
If so, the confirmation continuous similar frame is same number of frames；
Conversely, then confirming that the continuous similar frame is not same number of frames.
Wherein, in a specific example, after obtaining head video file, it can also save, specifically include respectively:
The first video, the second video remaining video frame after interception are saved as into first content video file, second respectively
Audio content file；
Head video file and first content video file, head video file and the second audio content file are obtained respectively
Related information, and be saved in database.
In actual operation, user needs to obtain out all collection numbers an of film.
Then by first collection, second collection video raw frames are decoded since first frame, with second collection first frame into
Row compares.
It is whether identical or can also compare whether the pixel of two frames exactly matches to compare two frames.But in some cases
Under, the exact matching of compared pixels point is relatively difficult to realize exactly match for video compression frames.
Specifically, by the way that screen resolution is reduced to such as 1/4, experimental data and reality is can be used in resolution ratio reduction
Conclusion progress is tested, such as 1/2 or 1/8 can also be reduced to.A possibility that resolution ratio due to will appear two videos is different, because
This is compared with a low point resolution can be to avoid certain situations: such as video is compressed into the color occurred after small resolution ratio
Difference just has large error compared with high-resolution.Because video be also possible to repeatedly compress be compressed to low resolution have turn
At high-resolution, actual color is to have lost.After the resolution ratio of the present invention preferably 1/4, and it can modify according to time situation.
For example the video of 1920x1080 and the video of 1280x720 compare, and resolution ratio are reduced to point all lower than the two numerical value
Resolution compares, and could reduce in this way due to video compress bring error.The video erection of 1920x1080 is h.265 to damage pressure
Contracting format rather than original video, color therein will be supplemented with difference arithmetic, and such supplement will lead to mistake when comparison
Difference is very big, and such error can be reduced by reducing resolution ratio, excludes the pixel that difference is calculated.
After reducing resolution ratio, then compare each pixel color tolerance ((each component value of R, G, B be [0~
255]), the value of three colors compares (10,10,10) respectively and (12,8,13) take wherein maximum difference 13-10=3, R and G poor
2) value absolute value is all.After comparison, predetermined ratio value can be selected to be both less than for the tolerance of 90% color based on experience value
10, then determine that two content frames are approximately uniform.
It should be understood that 90% is predetermined ratio value, it can rule of thumb judge to come, actual conditions tune can also be passed through
It is whole and obtain.Similarly, 10 be predetermined tolerance, can also rule of thumb be judged, can also pass through actual conditions and adjust acquisition.
If with second to collect the first content frame approximately uniform for the first collection first frame, continue to compare first the second frame of collection and the
Two the second frames of collection, until two frames are not approximately uniform.If consecutive identical frame number is greater than 10 seconds, (i.e. scheduled duration, can root
Adjusted according to actual conditions), then determine that there are continuous same number of frames for two collection.
The former frame of first collection first frame to the frame number for not being same number of frames is intercepted out, saves as individual head video
File.
Finally, can collect remaining frame number for first saves as first content video file, collects remaining frame number for second and save as
Second audio content file.This similar method can also be applied to the 3rd collection, the 4th collection etc..
By in head video file and first content video file related information deposit database, head video file and the
Two audio content file association informations are stored in database.It only needs to take out corresponding head according to related information after in this way and regard
Frequency file and audio content document order play the effect can reach and playing originally.
For convenience of it will be appreciated by those skilled in the art that being illustrated below by way of a specific example.
Such as: " the fiery shadow person of bearing " this film first compares the first collection and the second collection.By the first collection, the second collection video
The raw frames that resolution ratio is 640X480 are decoded since first frame and resolution ratio is reduced to 320X240, with the second collection
First frame is compared.Compare since first pixel of the picture of first frame, coordinate is the pixel of (x, y)=(0,0)
It is compared with the respective coordinates of the second collection for the color of the pixel of (x, y)=(0,0), such as first pixel of collection
The color of the pixel of (x, y)=(0,0) is that (10,10,10) and (12,8,13) take wherein maximum difference 13-10=3, R and G
Absolute difference is all 2) then to determine that two pixel colors of two collection are approximate.Then comparison (x, y)=(0,1), (x, y)=
(0,2) until until (x, y)=(319,239).Then ratio of the pixel tolerance less than 10 for counting all is greater than 90%
Then determine that this two content frame is approximately uniform.
If with second to collect the first content frame approximately uniform for the first collection first frame, continue to compare first the second frame of collection and the
Two the second frames of collection, until two frames are not approximately uniform.If consecutive identical frame number is greater than 10 seconds, there are continuous phases for two collection
It is at same frame.
The former frame of first collection first frame to not approximately uniform frame number is intercepted out, saves as individual head video
File.
Collect remaining frame number for first and save as audio content file 1, collects remaining frame number for second and save as video file 2.
This similar method can also be applied to the 3rd collection, the 4th collection.
