In the application, target video data is being obtained, and be based on preset cutting strategy, be by target video data cutting
After specific video data block, the video data block of preset quantity is stored with default storage mode.Originally by application
Video data cutting to be stored can be the video of preset quantity according to preset cutting strategy by the technical solution of application
Data block, and by the storage of each video data block into different storage locations.And then it can be incited somebody to action to avoid existing in the related technology
The easy the problem of being stolen occurred under the storage to same storage location of all videos data.
Optionally, in a kind of embodiment of the application, it is based on preset cutting strategy, by target video data cutting
May include any one of following two in embodiment for specific video data block:
First way:
Obtain the corresponding length of the video time of target video data；
Target video data cutting is the view of preset quantity by the size relation based on length of the video time and preset threshold
Frequency data block.
Firstly, the application can carry out cutting to target video data according to the video time length of target video.Wherein,
Target video is the corresponding video of target video data.The application can work as the time span for determining target video and preset
After the size relation of threshold value, target video data is divided into the video data block of preset quantity.
Further, when detecting that length of the video time is more than preset threshold, when by target video data according to video
Between length, average cutting is the video data block of the first preset quantity.
It should be noted that not being specifically limited to preset threshold in the application, such as preset threshold can be 100 points
Clock, preset threshold may be 200 minutes.Likewise, the application is not also specifically limited the first preset quantity, such as first
Preset quantity can be 10, and the first preset quantity may be 50.The specific variation of preset threshold and the first preset quantity is equal
It will not influence the protection scope of the application.
Optionally, when the video length for determining target video is more than preset threshold, determine that the video length is longer.Then originally
Application can carry out the cutting of equal portions to it.Wherein, in the video data block after every a cutting, corresponding length of the video time
It is all the same.
With preset threshold for 100 minutes, the first preset quantity is illustrated for 10, when the view for detecting target video
When frequency time span is 110 minutes, determine that the video length of target video is more than preset threshold.Further, then by the target
Video slicing is 10 parts of video data block, and the corresponding video length of every part of video data block is 11 minutes.
It is further alternative, when detect length of the video time be no more than preset threshold when, by target video data according to
The random cutting of size of data is the video data block of the second preset quantity.
It should be noted that not being specifically limited to the second preset quantity equally in the application, such as the second preset quantity
It can be 10, the second preset quantity may be 30.Second preset quantity can be identical as the first preset quantity, the second present count
Amount can also be not identical as the first preset quantity.
Optionally, when the video length for determining target video is less than preset threshold, determine that the video length is shorter.Then
The application can be to it into row stochastic cutting.Wherein, the size of data of the video data block after every a cutting can respectively not
It is identical.
With preset threshold for 100 minutes, the second preset quantity is illustrated for 5, when the view for detecting target video
When frequency time span is 90 minutes, determine that the video length of target video is less than preset threshold.Further, then by the target
The random cutting of video is 5 parts of video data block, and the corresponding size of data of every part of video data block respectively corresponds to.
The second way:
The key frame and non-key frame carried in detection target video data.
It is the video data block of the preset quantity by target video data cutting based on key frame and non-key frame.
It optionally, can include multiple image in video image, every frame image represents a static image.And
In actual video data, various algorithms can be taken to reduce the capacity of data, wherein just including key frame I frame (intra
) and non-key frame P frame picture.Further, I frame is key frame, is by being eliminated as much as image space redundancy
The in-frame encoding picture of compressed transmission data amount belongs to the complete reservation of frame data compression picture.And P frame is then to search for forward
Frame, expression are difference of this frame with a key frame (or P frame) before.It should be understood that P frame is generated based on I frame
Compressed data.
It is further alternative, since I frame image is first of each GOP (video compression technology used in MPEG)
Frame, P frame are to find out the predicted value and motion vector of some object from I frame using I frame as reference frame, prediction is taken obtained from
The image of difference and motion vector.It therefore can be based on key frame I frame and non-key frame P frame come by target video in the application
Data cutting is a number of video data block.
In a kind of possible embodiment of the application, realizes and be based on key frame and non-key frame, by target video data
Cutting is that the embodiment of the video data block of the preset quantity can be obtained by following:
Determine the crucial number of frames carried in target video data and the corresponding non-key frame quantity of each key frame；
It is specific by target video data cutting based on crucial number of frames and the corresponding non-key frame quantity of each key frame
Video data block, crucial number of frames with specifically for identical quantity.
Optionally, in order to avoid in cutting target video data, be not based on key frame I frame carry out cutting caused by
The problem of there may be video data error.Target video data can be cut according to the quantity of key frame in the application
Point.Further, it can be carried out using each key frame and its corresponding all non-key frame P frames as a video data block
Segmentation.It it should be understood that including how many key frame in the target video data, i.e., is the number by target video data cutting
The video data block of amount.
For example, when including following picture frame in some target video data:
I frame 1, P frame 1, P frame 2, P frame 3, P frame 4, I frame 2, P frame 5, P frame 6, I frame 3, P frame 7.
From the above, it can be seen that P frame 1, P frame 2, P frame 3, P frame 4 are the non-key frames for belonging to key frame I frame 1.P frame 5, P frame 6
It is the non-key frame for belonging to key frame I frame 2.P frame 7 is the non-key frame for belonging to key frame I frame 3.Further, in the application,
It can be 3 parts of video data block by target video data cutting according to the quantity based on key frame I frame.And according to each pass
The corresponding non-key frame quantity of key frame carries out cutting to every part of video data block.Specifically:
First part of video data block: I frame 1, P frame 1, P frame 2, P frame 3, P frame 4.
Second part of video data block: I frame 2, P frame 5, P frame 6.
Third part video data block: I frame 3, P frame 7.
It should be noted that the application equally can be based on key when in target video data including other key frames
Target video data cutting is specific video data block by number of frames and the corresponding non-key frame quantity of each key frame.
For example, B frame image is also non-key frame.Wherein, B frame is bi-directional predicted frames, is both to have considered and sequence of source images
The encoded frame in front also takes the time redundancy information behind sequence of source images between encoded frame into account and carrys out compressed transmission data amount
Coded image.B frame using before I frame or P frame and subsequent P frame as reference frame, the predicted value of " finding out " B frame " certain point " and two
Motion vector, and prediction difference and motion vector is taken to transmit.Receiving end calculates in two reference frames pre- according to motion vector
Measured value is simultaneously summed with difference, so as to obtain B frame image.
It should be understood that when in video data also include non-key frame B frame when, can using non-key frame B frame as its to
The preceding corresponding non-key frame of first key frame carries out the cutting of video data block group.Likewise, crucial number of frames remains unchanged
With the picture frame difference for specifically for identical quantity, only including in every part of video data block group.
It is further alternative, in a kind of embodiment of the application, (it is based on preset cutting strategy, by mesh in S102
Mark video data cutting is specific video data block) after, it further include a kind of specific embodiment, as shown in figure 3, packet
It includes:
S201 obtains target video data.
S202 is based on preset cutting strategy, is specific video data block by target video data cutting.
Corresponding mark is arranged to each video data block in S203, and mark belongs to target for characterizing each video data block
Video data.
In the application, can will by target video data cutting be specific video data block after, to each video
The mark for adhering to video data separately for characterizing each video data block is arranged in data block, wherein the application does not do specific limit to mark
It is fixed, such as mark can the information such as the user information of uploader and uplink time generate according to mark.It identifies and may be
The mark of the generations such as the parameter information according to target video data.As long as it should be understood that the mark may indicate that each number
Belong to its corresponding video data according to block.
It should also be noted that, the application does not equally do specific limit to the object that the corresponding mark of each video data block is arranged
It is fixed.Such as it can be generated for user and be arranged the corresponding mark of each video data block, it can also be generated and be arranged by server family
The corresponding mark of each video data block.
In addition, the application can by be added in the title suffix of every part of video data block corresponding parameter information etc. come
Every part of data block is set with corresponding mark, can also be believed by the way that the corresponding parameter that carries is added in every part of video data block
Each data block is arranged with corresponding mark in the data packet of breath.
Optionally, belong to its correspondence since the corresponding mark of each video data block can be used for distinguishing each data block
Video data can be found by the mark therefore in the subsequently received instruction for transferring the target video data
The corresponding all video data block of target video data.
S204 stores each video data block that corresponding mark is added with the default storage mode.
Each video data block is backed up, the corresponding backup video data block of each video data block is obtained.
Each video data block and each backup video data block are respectively stored into different servers.
Optionally, in the application can by target video data cutting be specific video data block after, to every part
Video data block is backed up accordingly, to avoid there is some video data block because can not restore caused by being stolen
The drawbacks of whole video data.
Further, the application is after the backup video data block for obtaining the backup of each video data block, in order to avoid
Occur the risk of each video data block storage to all loss of data caused by same position.The application can also be by each view
