Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, a flowchart illustrating steps of a video processing method according to an embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, the source video data may be used to represent the obtained source video, for example, the source video may be a video that is pre-stored in the terminal device, may also be a video that is currently downloaded from a server by the terminal device, may also be a video that is currently recorded by the terminal device, may also be a video that is searched through a video application in the terminal device, and so on.
In order to add a dynamically displayed watermark to video data, in the embodiment of the present invention, after determining a video that needs to be processed currently, source video data of the video and a corresponding watermark addition policy may be obtained, for example, the source video data and the watermark addition policy may be obtained by a video application in a terminal device, so that a watermark may be added to each frame of image data in the source video data corresponding to each step-by-step composite image according to the watermark addition policy subsequently. The watermarking strategy can be used for adding a dynamically displayed watermark in video data, and may include one or more of the following: watermark content, the number of frames corresponding to the watermark content, the watermark location, etc.
In particular, the watermark content may be used to determine what content needs to be displayed in the watermark image, and may include production information of the video, such as an application flag, a user identification, and the like, which may include a video application. The frame number corresponding to the watermark content can be used for determining the image frame number required for displaying a complete watermark image in the video data playing process, for example, when the frame number corresponding to the watermark content is M frames, continuous M frames of image data are required for displaying a complete watermark image in the video data; or the method may be used to determine the number of image frames required to display a step-by-step composite image corresponding to the watermark in the video data playing process, for example, when the number of frames corresponding to the watermark content is a frame, it may be determined that n consecutive frames of image data are required to display each step-by-step composite image corresponding to the watermark in the video data, if the watermark requires M compositing steps to perform compositing, it may be determined that the number of image frames required to display a complete watermark image in the video data playing process is the number of frames corresponding to the product of M and n, for example, when the product of M and n is M, it may be determined that M consecutive frames of image data are required to complete the display of each step-by-step composite image corresponding to a complete watermark in the video data, and so on. The watermark position may be used to determine a display position of the watermark in the video data, for example, may be used to determine a display position of a watermark image of the watermark in each frame of image data of the video data, and may also be used to determine a display position of each step-by-step synthesized image corresponding to the watermark in each frame of image data of the video data, and the like, which is not limited in this embodiment of the present invention.
And 104, extracting image data of each frame from the source video data.
Specifically, the video data of one video may include at least two frames of image data. According to the embodiment of the invention, after the source video data is acquired, the image data of each frame can be extracted from the source video data, so that the corresponding step-by-step synthetic image of the watermark is respectively added in the image data of each frame in the following process.
And 106, processing the image data according to the watermark adding strategy to obtain watermark image data of each frame.
Specifically, the embodiment of the present invention may process the image data according to the watermark adding policy based on the playing time sequence of each frame of image data, for example, each frame of image data and each step-by-step synthesized image corresponding to the watermark may be synthesized separately, so as to add the step-by-step synthesized image corresponding to the watermark to each frame of image data, and obtain each frame of synthesized watermark image data.
In an optional implementation manner, each step-by-step synthesized image corresponding to the watermark to be added may be determined according to the watermark adding policy, and then each step-by-step synthesized image corresponding to the watermark to be added may be sequentially and cyclically synthesized with each frame of image data to obtain each frame of watermark image data. The watermark to be added can be used for representing a watermark image which needs to be added currently in the source video. For example, the watermark image data can be circularly synthesized with each frame of image data in the source video data according to the synthesis sequence of the watermark image to obtain each frame of watermark image data of the step-by-step synthesized image added with the watermark image, so that the watermark image can gradually become complete along with the playing of each frame of watermark image data and can circularly appear in the playing interface corresponding to each watermark image data until each frame of watermark image data is played.
And 108, synthesizing the watermark image data into the target video data added with the watermark and storing the target video data.
After each frame of watermark image data of the step-by-step synthesized image corresponding to the added watermark is obtained, the target video data added with the watermark image can be synthesized according to each frame of watermark image data, for example, each watermark image data can be synthesized into the target video data added with the watermark according to the time stamp, and then the target video data added with the watermark can be stored, so that the target video data can be conveniently used subsequently.
For example, the target video data can be used for video playing to circularly display each step-by-step composite image of the watermark image in the video playing process, so that the watermark added to the target video data can be displayed in a dynamic mode, and the effect of adding the dynamic watermark to the video data is achieved; if the target video data can be used for video publishing, for example, a user can upload the target video data to a server corresponding to a video application, so that other users can obtain the target video data to which the dynamic watermark is added, the purpose of video sharing is achieved, meanwhile, the copyright of the published target video data can be protected based on the added dynamic watermark, and the protection effect of the video data is enhanced.
To sum up, after the source video data and the watermark adding strategy are obtained, each frame of image data can be extracted from the source video data, and the extracted frame of image data can be processed according to the watermark adding strategy to obtain each frame of watermark image data, namely, each step-by-step composite image corresponding to the watermark is added to each frame of image data in the source video data, and then the watermark image data can be synthesized into the target video data added with the watermark and stored, so that each step-by-step composite image corresponding to the watermark can be displayed in the subsequent process of playing the target video data, the purpose of displaying the dynamic watermark in the video data is realized, and the user requirement of adding the dynamic watermark in the video data is further met.
In the actual processing, after determining the watermark to be added to the video, the embodiment of the invention can generate a plurality of corresponding step-by-step composite images according to the synthesis steps corresponding to the watermark, so as to conveniently and circularly add each step-by-step composite image corresponding to the watermark in the source video data. In an optional embodiment of the present invention, may further include: determining a synthesis step corresponding to the watermark image according to the acquired watermark content and/or the frame number corresponding to the watermark content; a step-by-step composite image is generated according to each of the synthesis steps. Specifically, the watermark content may be determined according to a watermark material selected or input by a user, for example, the watermark content may be generated according to an application mark, a user name, a picture, and the like selected by the user; the application flag and/or the user identifier of the video application may also be determined according to default parameters, for example, the application flag and/or the user identifier of the video application may be determined as the watermark content to be watermarked, which is not limited in this embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, each step-by-step composite image corresponding to a watermark may be generated before source video data is acquired, so that each step-by-step composite image corresponding to a watermark to be added may be directly acquired when source video data is acquired subsequently, thereby facilitating subsequent addition of a watermark to video data.
Of course, after the source video data is acquired, the watermark adding strategy may also be acquired according to the watermarks that are required to be added to the source video data, the synthesizing step corresponding to the watermark is determined according to the watermark content in the watermark adding strategy and/or the frame number corresponding to the watermark content, and a step-by-step synthesized image may be generated according to each synthesizing step, so that each step-by-step synthesized image corresponding to the watermark to be added may be acquired, which is not specifically limited in the embodiment of the present invention.
Referring to fig. 2, a flowchart illustrating steps of a device detection method according to an alternative embodiment of the present invention is shown.
For example, after the user selects a video that needs to be processed, the terminal device may obtain source video data of the video through a video application, and may obtain a watermark adding policy corresponding to a watermark to be added for the source video, so as to execute step 204 according to watermark content in the watermark adding policy and/or a frame number corresponding to the watermark content. For another example, after the terminal device acquires the source video data of the video, it may acquire each step-by-step composite image corresponding to the watermark to be added for the video, and then jump to step 208 to execute, so as to add the distributed composite image corresponding to the watermark in each frame of image data of the source video data.
And 204, determining the synthesis steps corresponding to the watermark images according to the acquired watermark content and/or the frame number corresponding to the watermark content, and generating a step-by-step synthesized image according to each synthesis step.
After the watermark content and/or the frame number corresponding to the watermark content are/is acquired, the synthesis step corresponding to the watermark image can be determined according to the acquired watermark content and/or the frame number corresponding to the watermark content; therefore, after the corresponding synthesis step of the watermark image is determined, such as in the case of determining that the watermark image added by the video data is a micro mark (Logo) of a video application, if the Logo (Logo) of the video application is an icon consisting of a hexagon and a triangle, it may be determined that the corresponding compositing step of the watermark image comprises a hexagonal compositing step and a triangular compositing step, the step-by-step composite image corresponding to each synthesis step may be generated according to the synthesis sequence of the watermark image, that is, a first step-by-step composite image may be generated according to a first synthesis step, a second step-by-step composite image may be generated according to a second synthesis step, a third step-by-step composite image may be generated according to a third synthesis step, and the like until the step-by-step composite image corresponding to the last composite step of generating the watermark image.
For example, when the micro-mark applied to the video is an icon composed of a hexagon and a triangle, it may be determined that the synthesis step corresponding to the watermark image includes a hexagon synthesis step and a triangle synthesis step, as shown in fig. 3, the first step synthesis image 301 may be generated according to the first synthesis step, the second step synthesis image 302 may be generated according to the second synthesis step, the third step synthesis image 303 may be generated according to the third synthesis step, the fourth step synthesis image 304 may be generated according to the fourth synthesis step, the fifth step synthesis image 305 may be generated according to the fifth synthesis step, the sixth step synthesis image 306 may be generated according to the sixth synthesis step, the seventh step synthesis image 307 may be generated according to the seventh synthesis step, the eighth step synthesis image 308 may be generated according to the eighth synthesis step, the ninth step synthesis image 309 may be generated according to the ninth synthesis step, namely, the step-by-step composite image corresponding to the last composite step is completed, and a complete watermark image is obtained.
In the embodiment of the present invention, optionally, the watermark content may include an application mark and/or a user icon; wherein the application Logo can be used to identify the video application, such as an icon, Logo (Logo), etc. that may be the video application; the user identification may be used to determine the producer of the video, such as may be a user account number (ID) or the like.
And 208, synthesizing each step-by-step synthesized image corresponding to the watermark to be added with each frame of image data according to sequence circulation to obtain each frame of watermark image data.
After extracting each frame of image data in the source video data, the embodiment of the present invention may add and synthesize each step-by-step synthesized image corresponding to the watermark image to one frame or continuous multi-frame image data in a cycle according to the synthesizing order of the watermark image, for example, according to the positive order and/or the reverse order of the synthesizing steps, until the step of adding the step-by-step synthesized image corresponding to the watermark image to each frame of image data in the source video data is completed. The number of frames of image data to which a step-by-step synthesized image is added may be set according to the time required for displaying a complete watermark image and/or the number of synthesizing steps, or may be set according to the time required for a user to view a step-by-step synthesized image, which is not limited in the embodiment of the present invention. For example, it may be set that one step-by-step synthesized image needs to be added to consecutive n frames of image data, n being an integer greater than 1.
In an alternative embodiment, the synthesizing the to-be-watermarked step-by-step synthesized images with the frame image data according to a sequential loop may include: synthesizing each step-by-step synthetic image corresponding to the watermark to be added with continuous n frames of image data according to a positive sequence until the synthesis step of the last step-by-step synthetic image is completed; and circularly executing the synthesis steps. Specifically, according to the positive sequence of the synthesis steps, each step-by-step synthesis image corresponding to the watermark to be added is respectively added to the continuous n frames of image data for synthesis, that is, the same step-by-step synthesis image can be respectively synthesized with the continuous n frames of image data, so that the continuous n frames of watermark image data added with the same step-by-step synthesis image can be obtained until the synthesis step of the last step-by-step synthesis image is completed, and the watermark image can be gradually and completely displayed along with the playing of each frame of watermark image data; and then adding the next complete watermark image corresponding to each step-by-step synthesized image in the image data without the added step-by-step synthesized image until the step-by-step synthesized image corresponding to the watermark image is added to all the image data in the source video data, so that the watermark image can be circularly displayed in a playing interface corresponding to each watermark image data to realize the dynamic display of the watermark image, and the requirement of a user for adding the dynamic display watermark in the video data is met.
For example, when it is preset that one step-by-step synthesized image can be synthesized with consecutive 3 frames of image data, in combination with the above example, the first step-by-step synthesized image 301 can be synthesized with the first frame of image data, the second frame of image data, and the third frame of image data in the source video data, respectively, the second step-by-step synthesized image 302 can be synthesized with the fourth frame of image data, the fifth frame of image data, and the sixth frame of image data in the source video data, respectively, then the third step-by-step synthesized image 303 can be synthesized with the seventh frame of image data, the eighth frame of image data, and the ninth frame of image data in the source video data, and so on until the synthesizing step of the ninth step-by-step synthesized image 309 is completed; then, the first step-by-step synthesized image 301 is synthesized with the twenty-eighth frame image data, the twenty-ninth frame image data, and the thirty-third frame image data in the source video data, the second step-by-step synthesized image 302 is synthesized with the thirty-first frame image data, the thirty-twelfth frame image data, and the thirty-third frame image data in the source video data, and so on until the step of adding the distributed synthesized image to each frame image data of the source video data is completed.
In another alternative embodiment, the synthesizing the image to be watermarked corresponding to each step by step with the image data of each frame according to a sequential cycle may include: synthesizing each step-by-step synthetic image corresponding to the watermark to be added with continuous n frames of image data according to a positive sequence until the synthesis step of the last step-by-step synthetic image is completed; synthesizing each step-by-step synthesized image corresponding to the watermark to be added with continuous n frames of image data according to a reverse order until the step of synthesizing the first step-by-step synthesized image is completed; and circularly executing the synthesis steps. Specifically, according to the positive sequence of the synthesis steps, each step-by-step synthesis image corresponding to the watermark to be added is respectively added to the continuous n frames of image data for synthesis, that is, the same step-by-step synthesis image can be respectively synthesized with the continuous n frames of image data, so that the continuous n frames of watermark image data added with the same step-by-step synthesis image can be obtained until the synthesis step of the last step-by-step synthesis image is completed, and the watermark image can be gradually and completely displayed along with the playing of each frame of watermark image data; then, according to the reverse order of the synthesis steps, each step-by-step synthesis image corresponding to the watermark to be added is respectively added into the continuous n frames of image data for synthesis until the synthesis step of the first step-by-step synthesis image is completed, so that the watermark image can be circularly executed along with the gradual disappearance of the playing of each frame of watermark image data, the synthesis steps are circularly executed, the watermark image can be gradually displayed and gradually disappeared again in the playing process of each frame of watermark image video data, then the information is gradually displayed and gradually changed, and the information is circularly displayed in the playing interface corresponding to each watermark image data, thereby realizing the dynamic display of the watermark image.
For another example, in a case where it is preset that one step-by-step synthesized image can be synthesized with consecutive 3 frames of image data respectively, after the first to ninth step-by-step synthesized image synthesizing steps are completed in the forward order of the synthesizing steps, the ninth step-by-step synthesized image 309 may be synthesized with the twenty-eighth, twenty-ninth, and thirty-third frames of image data in the source video data in the reverse order of the synthesizing steps, and then the eighth step-by-step synthesized image 302 may be synthesized with the thirty-eleventh, thirty-twelfth, and thirty-third frames of image data in the source video data, and so on until the synthesizing step of the first step-by-step synthesized image 301 is completed; and then, executing a step of synthesizing the watermark image corresponding to each step of synthesized image according to the positive sequence of the synthesizing step, and after nine steps of synthesized image according to the positive sequence of the synthesizing step are completed, completing the step of synthesizing the watermark image corresponding to each step of synthesized image according to the reverse sequence, and so on until the step of adding the distributed synthesized image in each frame of image data of the source video data is completed.
In an optional embodiment of the present invention, the synthesizing each step-by-step synthesized image corresponding to the watermark to be added with the consecutive n frames of image data respectively may include: synthesizing the continuous n frames of image data and the step-by-step synthesized image corresponding to the watermark to be added; and then synthesizing the next continuous n frames of image data and the next step-by-step synthetic image corresponding to the watermark to be added until all the step-by-step synthetic images corresponding to the watermark to be added are synthesized.
And step 210, synthesizing the watermark image data into watermark-added target video data according to the time stamp, and storing the watermark-added target video data.
Specifically, the embodiment of the present invention may synthesize each watermark image data according to the timestamp corresponding to the source video data, thereby generating the target video data to which the watermark is added, and then store the target video data to which the watermark is added, so as to facilitate subsequent use of the target video data.
