Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, when a video is backed up, the complete video is stored in different storage spaces, for example, the video may be stored in different storage spaces of the same electronic device or the same server, or the video may be stored in different electronic devices or different servers.
Since the complete videos are stored separately, a large amount of storage resources are occupied, and if the videos need to be stored to different electronic devices or different servers, a large amount of bandwidth resources are also occupied.
Based on this, embodiments of the present application provide a data processing method, an apparatus, an electronic device, a storage medium, and a computer program product, where a video is split into at least two groups of differential backup data, and video images included in different groups of differential backup data are not overlapped. Different groups of differential backup data are stored in different storage spaces, the storage resources occupied by one group of differential backup data are smaller than the storage resources occupied by a complete video, and if the differential backup data can be used as the backup video of the video, the storage resources occupied by one or more backup videos of the video are reduced compared with the related art; if different groups of differential backup data need to be stored in different electronic devices or different servers, the bandwidth resource occupied by one group of differential backup data is smaller than that occupied by one complete video, and compared with the related technology, the bandwidth resource occupied by one or more backup videos of the videos in the transmission process is reduced.
The following describes a data processing method provided in an embodiment of the present application with reference to the drawings.
As shown in fig. 1, which is a flowchart of a data processing method provided in an embodiment of the present application, the method includes steps S101 to S102.
Step S101: the video is split into at least two sets of differential backup data.
Wherein each set of the differential backup data includes a plurality of video images. A first number of video images belonging to other groups of difference backup data are spaced between two adjacent video images of the difference backup data in the same group, wherein the first number is the difference between the number of the at least two groups of difference backup data and 1; the two adjacent video images can represent the content contained in the first number of video images which belong to other groups of difference backup data and are spaced between the two adjacent video images in the video; the video images contained in different groups of the differential backup data are positioned at different positions of the video, and the video is formed by the at least two groups of the differential backup data.
The "video images of the difference backup data belonging to the other groups with the first number of intervals between two adjacent video images of the difference backup data in the same group" means that the video images of the first number of intervals between two adjacent video images of the difference backup data belonging to the same group in the video belong to the other groups with the first number of video images. The following examples are given.
As shown in fig. 2a and fig. 2b, a schematic diagram of splitting a video image of each frame included in a video provided by the embodiment of the present application is shown.
As shown in fig. 2a, the video 21 comprises 16 frames of video images. The number of the at least two groups of difference backup data is 2, that is, the first number is 1, in the video 21, one rectangular area represents one frame of video image, wherein the rectangular area filled with the same pattern represents the video image belonging to the same group of difference backup data, and as can be seen from fig. 2a, two adjacent video images belonging to the same group of difference backup data in the video 21 are separated by one frame of video image belonging to other groups of difference backup data.
The video 21 may be split into differential backup data 22 and differential backup data 23 as shown in fig. 2 a.
As shown in fig. 2b, the video 24 comprises 25 frames of video images. The number of the at least two groups of difference backup data is 3, that is, the first number is 2, in the video 24, one rectangular area represents one frame of video image, wherein the rectangular area filled with the same pattern represents the video image belonging to the same group of difference backup data, and as can be seen from fig. 2b, two frames of video images belonging to other groups of difference backup data are separated between two adjacent video images belonging to the same group of difference backup data in the video 24.
Fig. 2a illustrates an example that the number of the at least two sets of differential backup data is 2, and fig. 2b illustrates an example that the number of the at least two sets of differential backup data is 3, but the number of the at least two sets of differential backup data is not limited in this application embodiment, and for example, the number of the at least two sets of differential backup data may also be 4, 5, 6, ….
The above "the two adjacent video images can represent the content included in the video images of the first number belonging to the other group of difference backup data at the interval between the two adjacent video images in the video" means that the two adjacent video images belonging to the same group of difference backup data in the video can represent the content included in the video images of the first number located between the two adjacent video images. Taking fig. 2b as an example, two adjacent frames of video images 241 and 242 belonging to the same group of difference backup data in fig. 2b can represent the content contained in the video image 243 and the video image 244, and it can be understood that the video image 241 and the video image 242 themselves can represent the content contained in themselves.
It is understood that, when recording a video, the greater the number of video images recorded per second (i.e., the higher the frame rate), the higher the similarity between the contents contained in two or more adjacent video images.
Illustratively, the higher the frame rate, the greater the number of the at least two sets of differential backup data; the lower the frame rate, the smaller the number of the at least two sets of differential backup data.
For example, the number of the at least two sets of differential backup data may be determined based on a frame rate of the video.
Since "the two adjacent video images can represent the content included in the video images belonging to the other groups of difference backup data of the first number spaced between the two adjacent video images in the video", each group of difference backup data can be used as a backup video of the video, that is, a user can know all the content of the video by watching the difference backup data.
Since each set of differential backup data has a lower frame rate than the video, when the user views the differential backup data, the image may not be smooth.
For example, the resolution of the video image contained in the differential backup data may be lower than or higher than or equal to the resolution of the video image contained in the video.
For example, the size of the video image included in the differential backup data may be larger than or smaller than or equal to the size of the video image included in the video.
Step S102: and respectively storing the at least two groups of difference backup data.
In an alternative implementation, different sets of differential backup data may be stored in different storage spaces of the same electronic device or the same server, respectively.
For example, the electronic device may be any electronic product that can interact with a user through one or more ways such as a keyboard, a touch PAD, a touch screen, a remote controller, a voice interaction device, or a handwriting device, for example, a mobile phone, a notebook computer, a tablet computer, a palm computer, a personal computer, a wearable device, a smart television, a PAD, and the like.
The server may be, for example, one server, a server cluster composed of a plurality of servers, or a cloud computing server center. The server 13 may include a processor, memory, and a network interface, among others.
In an alternative implementation, different sets of differential backup data may be stored in different electronic devices or different servers, respectively.
In the data processing method provided by the embodiment of the application, a video is split into at least two groups of differential backup data; wherein each set of the differential backup data comprises a plurality of video images; a first number of video images belonging to other groups of difference backup data are spaced between two adjacent video images of the difference backup data in the same group, wherein the first number is the difference between the number of the at least two groups of difference backup data and 1; the two adjacent video images can represent the content contained in the first number of video images which belong to other groups of difference backup data and are spaced between the two adjacent video images in the video; the video images contained in different groups of the differential backup data are positioned at different positions of the video, and the video is formed by the at least two groups of the differential backup data. Since "the two adjacent video images can represent the content included in the video images of the first number of the video images belonging to the other groups of the differential backup data at the interval between the two adjacent video images in the video", each group of the differential backup data can be used as the backup video of the video, that is, the user can know all the content of the video by watching the differential backup data. Because the number of the video images contained in the difference backup data is less than that of the video images contained in the video, the difference backup data is used as the backup video of the video, and compared with the related technology, the storage resources occupied by one or more backup videos of the video are reduced; if different groups of differential backup data need to be stored in different electronic devices or different servers, compared with the related art, the bandwidth resources occupied by one or more backup videos of the videos in the transmission process are saved.
In an optional implementation manner, because different sets of differential backup data are stored in different storage spaces, if the differential backup data stored in a certain storage space is damaged, a backup video may be obtained based on one or more undamaged differential backup data. The specific steps include A1 to A2.
Step A1: obtaining one or more groups of the differential backup data in the at least two groups of the differential backup data.
Step A2: a backup video comprised of the one or more sets of the differential backup data is obtained.
Illustratively, the differential backup data comprises a plurality of frames of video images and a plurality of frames of video images respectively located at the positions of the videos; one or more groups of the differential backup data can be merged into the backup video based on that the plurality of frames of video images respectively contained in one or more groups of the differential backup data are respectively located at the position of the video.
In an alternative implementation, one differential backup data may be obtained from one or more non-damaged differential backup data, and the differential backup data may be used as a backup video.
It can be understood that, since the frame rate of the differential backup data is lower than that of the video, when the user views the differential backup data, the picture may not be smooth.
For example, the application scenario of the data processing method provided in the embodiment of the present application may be as follows: the application scene of using the video as evidence is, for example, the scene of recording the video by a video recorder, or the scene of recording the video by law enforcement officers in the law enforcement process.
In an alternative implementation manner, there are various implementation manners of step S101, and the embodiment of the present application provides, but is not limited to, the following two.
In a first implementation manner, splitting a video in a video recording process specifically includes steps B11 to B14.
Step B11: and if the operation of starting recording the video is detected, starting the image acquisition device.
Illustratively, the image capture device may be a camera.
For example, the operation of starting to record the video can be a voice operation or a touch operation or a gesture operation.
Step B12: and controlling the image acquisition device to acquire the video image.
Step B13: and dividing the video image into corresponding difference backup data based on the position of the video image acquired at the current time in the recorded video.
It is appreciated that the number of video images contained in a recorded video increases over time.
Step B14: and returning to the step B13 until the operation of finishing recording the video is detected.
It is understood that the image capturing means captures the video image until the end of the video recording operation is detected. The current time involved in step B13 is different each time step B13 is executed, so the video image captured at the current time is different each time step B13 is executed.
In an alternative implementation, step S102 may be located between step B13 and step B14. After determining the difference backup data to which the video image acquired at the current time belongs, directly storing the video image into a storage space for storing the difference backup data.
It can be understood that, if the recorded video is important, each frame of video image can be split and stored in real time in the process of recording the video, for example, a law enforcement officer records a scene of the video in the process of law enforcement officer, and the situation that the recorded video cannot be obtained due to damage of recording equipment caused by fighting may occur in the process of law enforcement officer.
In an alternative implementation manner, step S102 may be located after step B14, that is, after the video recording is finished, the at least two sets of difference backup data are obtained, and then the at least two sets of difference backup data are stored.
In an optional implementation manner, the recorded video may be stored locally, that is, the data processing method further includes: and storing the video consisting of the video images acquired by the image acquisition device.
In an alternative implementation, the recorded video may not be stored locally.
The first implementation manner, splitting the existing video, specifically includes step B21 to step B22.
Step B21: determining a plurality of frames of video images contained in the video to be backed up.
Step B22: for each frame of the video image, dividing the video image into corresponding difference backup data based on the position of the video image in the video.
In an optional implementation manner, after determining the difference backup data to which the video image belongs, the video image is directly stored in a storage space for storing the difference backup data.
In an optional implementation manner, after the at least two sets of differential backup data are obtained, the at least two sets of differential backup data are stored.
In an alternative implementation, the at least two sets of difference backup data include a first difference backup data and a second difference backup data, then the step of dividing the video image into the corresponding difference backup data based on the position of the video image in the recorded video includes the following steps C1 to C2.
Step C1: and if the positions of the video images acquired at the current time, which are located in the recorded videos, are odd numbers, dividing the video image set into first difference backup data.
Step C2: and if the position of the video image in the recorded video acquired at the current time is an even number, dividing the video image into second difference backup data.
In an alternative implementation, the at least two sets of differential backup data include a first differential backup data and a second differential backup data, then the step of dividing the video image into the respective differential backup data based on the position of the video image in the video includes the following steps D1 to D2.
Step D1: and if the video image is positioned at the odd number of the video positions, dividing the video image set into first difference backup data.
Step D2: and if the position of the video image in the video is an even number, dividing the video image into second difference backup data.
