Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Referring to fig. 1, a flowchart of a video processing method provided in an embodiment of the present application is shown in fig. 1, where the method may include the following steps:
s11, anti-counterfeiting information of the target video is obtained.
In this embodiment of the application, the target video is a video to be processed, and the video may be a video in a generation stage, such as a video in a clipping stage and an editing stage, or a video in a playing stage, that is, a video that has been clipped, edited, and played in a terminal having a display screen.
As an embodiment, if it is determined that the target video is in the generation stage, copyright information of the target video may be acquired as the anti-counterfeiting information, where the copyright information may be an ID of a video producer, a production date, and the like. In practical applications, the copyright information may be input by a video producer or pre-stored in a preset location and then directly acquired from the preset location.
As another embodiment, if it is determined that the target video is in the playing stage, the playing end device information and the user information may be obtained as anti-counterfeit information, where the playing end device may be a mobile phone, a computer, or other device with a display screen, the playing end device information may include information such as a device model, an IMEI code (an international mobile equipment identity of the device), a UUID (a unique identifier of the device), and an IMSI (an international mobile subscriber identity of the device), and the user information may include information such as a user name. In practical applications, the information of the playing terminal device may be directly obtained from the playing terminal, and the user information may be input by a user or pre-stored in a preset position of the playing terminal device, and then directly obtained from the preset position.
And S12, encoding the anti-counterfeiting information to obtain corresponding encoded information.
The anti-counterfeiting information is usually a plain text consisting of characters, numbers, letters and the like, and is easy to be falsified, and the formats of different anti-counterfeiting information are not uniform, some anti-counterfeiting information are pure numbers, some anti-counterfeiting information are pure letters, and the numbers and the letters are combined, so that in order to improve the safety and the uniformity of the anti-counterfeiting information, the anti-counterfeiting information is coded according to a preset coding strategy, and the anti-counterfeiting information is converted into corresponding coding information.
As an embodiment, when encoding the anti-counterfeit information, the anti-counterfeit information may be encoded based on a preset moss code comparison table to obtain a corresponding moss code.
In practical application, a Morse code translator can be preset, and then the Morse code translator converts the anti-counterfeiting information into the Morse code.
Furthermore, because the Morse code translator can only convert letters, numbers and punctuation marks into Morse codes generally, but can not translate Chinese into the Morse codes directly, before the anti-counterfeiting information is converted into the Morse codes, whether the anti-counterfeiting information contains Chinese characters can be detected, if the anti-counterfeiting information contains the Chinese characters, the Chinese characters are converted into binary characters, and then the Morse codes translate the converted anti-counterfeiting information, so that the Morse codes corresponding to the anti-counterfeiting information are obtained.
S13, determining the display duration corresponding to each code symbol in the code information based on the corresponding relation between the preset code symbol and the display duration, wherein the display duration represents the display duration of the anti-counterfeiting mark.
In the embodiment of the application, the corresponding relation between the code symbols and the display duration of the anti-counterfeiting mark is preset, and the display durations corresponding to different code symbols are different. For example, the coded information is a morse code, where a morse code symbol "-" may correspond to 1 Ts, a "-" may correspond to 3Ts, and the length of Ts may be set according to the length of the target video.
Preferably, in order to ensure that the finished coded information can be displayed in the target video and reduce the occlusion of the video frame caused by the anti-counterfeiting mark, the length of Ts may be set to be smaller, for example, Ts may be 1 second.
S14, determining the display time corresponding to each display time length, wherein the display time is the display time of the anti-counterfeiting mark in the target video.
In the embodiment of the present application, the presentation time is a time when the anti-counterfeit mark is presented in the target video, the presentation time length of each code symbol corresponds to a presentation time, one presentation time is actually a time interval, and the length of the time interval is consistent with the presentation time length corresponding to the presentation time, for example, the presentation time length corresponding to the presentation time length Ts is a time interval with a length of Ts. And the anti-counterfeiting mark can be displayed in the target video within the time interval corresponding to the display time.
As an embodiment, as shown in fig. 2, determining the presentation time corresponding to each presentation duration may include the following steps:
and S21, sequencing the display duration corresponding to each code symbol in the coding information according to the arrangement sequence of the code symbols in the coding information to obtain a display duration vector.
As an embodiment, the presentation duration vector may be a 1 × n matrix, where n is the number of the coding symbols included in the coding information, and the arrangement order of the presentation durations included in the presentation duration vector is the arrangement order of the coding symbols corresponding to the presentation durations in the coding information.
An example, for an example that the encoded information is "- - - - - - - - - -" is taken as an example, a morse code symbol included therein is "-" "-" "" "", then a corresponding display duration according to "-" "is 1 Ts, a corresponding display duration according to" - "" is 3Ts, and a finally obtained display duration vector is (3Ts, 3 Ts.
And S22, acquiring the initial adding time and the interval duration.
The starting adding time is the playing time corresponding to the first video frame added with the anti-counterfeiting mark in the target video, namely the anti-counterfeiting mark is not added in the video frame before the starting adding time in the target video. The initial adding time may be set by the user according to actual requirements, or may be a fixed playing time, such as 01: 00. The interval duration is the interval duration between two adjacent display times, and the anti-counterfeiting mark is not displayed within the interval duration. The interval duration can be preset according to actual requirements.
It can be seen from the above that, in the embodiment of the application, the anti-counterfeit mark is not always displayed in the whole target video, but is displayed only after the initial adding time, and is not displayed within the interval duration, so that the occlusion of the anti-counterfeit mark on the video picture in the target video can be effectively reduced as a whole.
And S23, determining the display time corresponding to each display time length based on the initial adding time, the interval time length and the display time length vector.
As an embodiment, the display time corresponding to each display duration may be calculated by the following method:
for the display duration arranged at the first position in the display duration vector, the start time of the corresponding display duration may be the start adding time, and the end time may be the sum of the start adding time and the display duration, for example, if the start adding time is 00:00 and the display duration is 1s, the display duration corresponding to the display duration is 00:00-00: 01.
The display time corresponding to the display time except the display time arranged at the first position in the display time vector can be calculated in the following way:
the starting time of the display time corresponding to the display duration is the sum of the ending time of the display time corresponding to the display duration arranged one bit before the display duration and the interval duration, and the ending time of the display time corresponding to the display duration is the sum of the starting time of the display time and the display duration. For example, if the presentation duration is 3s, the end time of the presentation time corresponding to the presentation duration that is one bit before the presentation duration is 00:01, and the interval duration is 1s, the presentation time corresponding to the presentation duration is 00:02-00: 05.
The display time corresponding to each display time can be calculated through the method.
And S15, adding an anti-counterfeiting mark to a target video frame corresponding to the playing time and any display time in the target video.
In the embodiment of the application, after the display time corresponding to the anti-counterfeit mark is determined, a video frame (hereinafter referred to as a target video frame) whose playing time corresponds to any display time in the target video can be searched based on the display time, where the playing time corresponds to any display time, that is, the playing time belongs to any display time, for example, one display time is 00:02-00:05, and if the playing time of one video frame is 00:03, the video frame is determined to be the target video frame.
Specifically, the target video may be split into a plurality of video frames, and then the playing time of each video frame is compared with all the display times, so as to determine the target video frame corresponding to the playing time and any display time.
After the target video frame is determined, the anti-counterfeiting mark is added into the target video frame, and then the target video frame added with the anti-counterfeiting mark is added into the target video again, so that the anti-counterfeiting mark can be displayed within the display time corresponding to the anti-counterfeiting mark when the target video is played.
In the embodiment of the present application, the target video may be a video in a generation stage, and may also be a video in a playing stage.
As an embodiment, if it is determined that the target video is in the generation stage, after the target video frame is determined, the image of any area in the target video frame is replaced with the anti-counterfeiting mark before the target video frame is encoded.
As another embodiment, if it is determined that the target video is in the playing stage, after the target video frame is determined, the image of any area in the target video frame is replaced with the anti-counterfeiting mark before the target video frame is rendered.
As an example, the arbitrary area may be a pre-designated security mark placement area. Specifically, the user may designate an area as the anti-counterfeit mark placement area according to actual requirements, for example, may designate an area of 10 pixels away from each of the upper left corner and the left boundary of each video frame as the anti-counterfeit mark placement area. The anti-counterfeiting mark is added in such a way, so that the anti-counterfeiting mark can be conveniently positioned in the subsequent detection process of the anti-counterfeiting mark.
As another example, the arbitrary region may be an arbitrary region in a randomly selected target video frame. For example, a plurality of selectable regions may be preset for each video frame, for example, regions at four positions of top left, bottom left, top right, and bottom right of the video frame are used as the selectable regions, and then one of the selectable regions is randomly selected for adding the anti-counterfeiting mark for each video frame. By the method, the situation that illegal personnel cover the anti-counterfeiting marks in all the target video frames based on the placement area of the anti-counterfeiting marks in one target video frame can be effectively avoided.
Furthermore, after the area for adding the anti-counterfeiting mark is selected from the plurality of selectable areas, the distinguishing mark which is different from the anti-counterfeiting mark is added to other non-selected selectable areas, so that the area for adding the anti-counterfeiting mark can be positioned according to the distinguishing mark and the selectable areas when the anti-counterfeiting mark is detected subsequently.
Further, as an embodiment, the anti-counterfeit mark may be fixed or may be selected by the user according to the requirement, so that before the anti-counterfeit mark is added to the target video frame, a process of determining the anti-counterfeit mark may be further included.
As one example, the security feature may be determined in the following manner:
the method comprises the steps of presetting an anti-counterfeiting mark library, wherein the anti-counterfeiting mark library comprises a plurality of anti-counterfeiting marks, the anti-counterfeiting marks can be coding color blocks which are not obvious and can be identified (such as color blocks which are shown in figure 3 and are formed by squares with the color of A and triangles with the color of B and fixed inside the squares), displaying an anti-counterfeiting mark selection interface before adding the anti-counterfeiting marks to a target video frame, displaying the anti-counterfeiting marks in the anti-counterfeiting mark selection interface, enabling a user to select the required anti-counterfeiting marks from the anti-counterfeiting mark selection interface according to requirements, and enabling the anti-counterfeiting marks selected by the user to be used as the anti-counterfeiting marks to be added to the target video frame based on the selection operation of the user.
Further, if the selection operation of the user is not received within the preset time, one anti-counterfeiting mark can be randomly selected from the plurality of anti-counterfeiting marks to serve as the anti-counterfeiting mark added to the target video frame, or a preset default anti-counterfeiting mark can be used as the anti-counterfeiting mark added to the target video frame.
Further, if the anti-counterfeiting mark selection interface does not have the anti-counterfeiting mark required by the user, that is, the anti-counterfeiting mark library does not have the anti-counterfeiting mark desired by the user, the user can click an import button in the anti-counterfeiting mark selection interface to jump to the import interface, import the anti-counterfeiting mark stored in the local file or downloaded from the network into the import interface, then take the anti-counterfeiting mark imported by the user as the anti-counterfeiting mark added into the target video frame, and add the imported anti-counterfeiting mark into the anti-counterfeiting mark library.
By the mode, the self-definition of the anti-counterfeiting mark can be realized, so that the user experience is improved.
The application provides a video processing method, which comprises the steps of obtaining anti-counterfeiting information of a target video, coding the anti-counterfeiting information to generate corresponding coded information, determining display duration corresponding to each coded symbol in the coded information based on the corresponding relation between a preset coded symbol and anti-counterfeiting mark display duration, determining display time corresponding to each display duration, and adding an anti-counterfeiting mark in a target video frame corresponding to the playing time and the display time in the target video. So, only need add anti-fake mark in the target video frame, need not to add anti-fake mark to whole target video to reduce the sheltering from of anti-fake mark to the video picture on the whole, and this application has realized the anti-fake information of code in the time dimension, compares in directly adopting watermarks such as platform mark, and this scheme has promoted anti-fake information's security moreover, makes anti-fake information be difficult for being falsified.
In another video processing method provided by another embodiment of the present application, on the basis of the above embodiment, the method may further include:

For example, if the first presentation time corresponding to the presentation time length arranged at the first position is 00:00-00:01, the end time of the first presentation time corresponding to the presentation time length arranged at the last position is 00: 50, the cycle duration is 10min, then the second display time corresponding to the display duration arranged at the first position is 10: 50-10:51.

The manner of calculating the third display time, the fourth display time, and the like is similar to the manner of calculating the second display time, taking the calculation of the third display time as an example, that is, the starting time of the third display time of any display time duration is the sum of the corresponding starting time of the second display time, the time difference value and the cycle time duration, and the ending time of the corresponding third display time is the sum of the starting time of the third display time and the display time duration.
And all the display time corresponding to each display time length obtained by calculation is used as final display time for determining the target video frame, and the cyclic display of the anti-counterfeiting information in the target video can be realized by the mode.
