Detailed Description
In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure. It is to be understood that the described embodiments are only a few, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the disclosure without making any creative effort shall fall within the scope of protection of the disclosure.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of systems and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In the related technology, video playing software can preset screenshot and sharing functions, after user screenshot is completed, the software can display a sharing control, so that the user can share the screenshot in specific social software through one key of the sharing control, and therefore the efficiency of sharing the screenshot in the video playing software is remarkably improved.
For example, a screenshot button may be preset in video playing software, and if an interactive operation on the screenshot button is received in a video playing process, a currently played picture can be screenshot, and a one-key sharing button is further displayed, so that when the interactive operation on the one-key sharing button is received, a sharing panel is popped up, and a user can quickly screenshot in the video playing process and share the screenshot in social software such as instant messaging software, an email box and a web blog.
However, the above scheme cannot improve the efficiency of sharing the screenshot in other scenarios; for example, if a user tries to share a screenshot generated in advance by the video playing software in a social comment scenario, the user needs to open a screenshot directory of the video playing software in a system album, retrieve a previously generated screenshot file, and insert the screenshot file into the social comment; the above process is inefficient, resulting in poor user experience.
Based on the above, the present disclosure provides a technical solution for capturing a target picture from a target video in a playing process of the target video and adding the captured target picture to an expression library.
When the method is implemented, the expression library may be an expression library for providing alternative expressions for the social speech; specifically, the expression library may be an expression library of social software other than the video playing software, or may be an expression library of the video playing software itself. For example, part of the video playing software can also provide social speech functions such as video comments and instant barrage, so that the target picture captured in the video playing software can be directly added into an expression library of the video playing software for the user to quickly select the target picture under the condition of the social speech such as video comments and barrage.
In the technical scheme, the target picture generated based on the target video is stored in the expression library, and the screenshot scene is communicated with the social speaking scene, so that the user can quickly find the target picture from the alternative expressions in the expression library when speaking in the social speaking, the video screenshot sharing efficiency under the social speaking scene can be obviously improved, and the user experience is improved.
The following describes the technical solution by using a specific embodiment and combining a specific application scenario.
Referring to fig. 1, fig. 1 is a flowchart illustrating a picture saving method according to an exemplary embodiment, which may be applied to a client, and includes the following steps:
s201, playing a target video;
s202, generating a target picture based on at least one frame of image of the target video;
s203, adding the target picture to an expression library for providing alternative expressions for the social speech.
The client may include any form of electronic device, such as a personal computer, a smart phone, a tablet computer, an interactive television, a smart watch, and the like, and those skilled in the art may apply the technical solution of the present disclosure to a specific electronic device according to a specific service requirement.
In this example, the client may play the target video. Specifically, the client may play the target video in a full-screen playing manner, may play the target video in a split-screen playing manner using a partial screen space of the client, and may play the target video in a floating window or the like. Taking the client as an example of a smart phone, the situation that a movie or a short video stream is played in a full screen mode, a video is played in a half screen mode and video comments are displayed at the same time, a commodity video is played in a floating window when an e-commerce detail page is displayed, and the like can be regarded as a process for playing a target video. It can be seen that the specific playing mode of the target video does not need to be further listed or limited in the present disclosure.
The target video can comprise any kind of video works; from the angle of an acquisition mode, the target video can comprise a live video and an on-demand video; from the content perspective, the target video may include videos produced by professionals, such as movies, dramas, art programs, and the like, and also may include videos produced by users, such as life records, talent shows, skill sharing, and the like; those skilled in the art can apply the above technical solution of the present disclosure to any kind of target video according to specific service requirements.
In this example, the client may generate a target picture based on at least one frame of image of the target video; generally, a video file may include multiple frames of images, and the client may generate a target image according to at least one frame of the multiple frames of images, that is, a screenshot process. In the process of generating the target picture based on the at least one frame of image of the target video, the at least one frame of image may be directly used as the content of the target picture, or the target picture may be obtained by processing the at least one frame of image. For example, if the target video is a video with a specification of 1920 × 1080@24fps (1920 pixels in horizontal direction, 1080 resolution in vertical direction, 24 frames per second), where 12 consecutive frames from the xth second are used for generating the target picture, in this case, in order to reduce the capacity of the generated target picture, the 12 consecutive frames may be compressed, for example, the image size is reduced, the dynamic range is compressed, a picture compression algorithm is applied, and the like, so as to obtain the target picture with small capacity and convenient network transmission; it can be understood that the modes of compressing the image size, the color depth, and the like, and extracting frames, and the like, are all available image processing means, and the specific mode of image processing in the present disclosure does not need to be specifically limited, and a person skilled in the art can select an image processing mode according to specific service requirements and processing performance of the client.
In an embodiment, the target picture may be a target moving picture including a plurality of frames of images; compared with a static picture, a multi-frame image contained in a dynamic picture can carry more information, so that the contents such as actions, expressions and the like which need to change along with time can be better displayed; in addition, the dynamic picture is more interactive and striking compared with the static picture, and the social requirement of the user can be better met in the social speaking.
In this example, the client may add the target picture to an expression library for providing alternative expressions for social speech after the target picture is generated. The social speech can include any behavior of sending information to the social space of the internet, public information such as video comments, microblogs and friend circles, semi-public information such as private letters in a station, e-mails and short messages sent to a specified target, blog logs which are only visible by the user, and the like.
In an embodiment, the social speech may include a social system implemented by video software playing the target video; for example, the target video may be a short video, a short video application playing the short video may have a social system such as video comments and personal dynamics, and a behavior of a user posting the video comments and the personal dynamics in the short video application may be regarded as the social speaking behavior.
It can be understood that when the client adds the target picture to the expression library, the client may display a confirmation control, and after confirmation by the user, add the target picture to the expression library, or may add the target picture in a background silent manner without displaying a confirmation space. The action added to the emoticon library may also be referred to as save, collect, save, etc., and the present disclosure need not be limited to a specific designation for that action.
Referring to fig. 2, fig. 2 is an exemplary diagram illustrating an interface for social speech in an exemplary embodiment; in this example, the social speech specifically refers to a comment posting scenario in the video application, and after the video application receives an instruction of "insert expression" input by the user through the operation control, the video application may present an expression library containing the aforementioned target picture, so that the user may select an expression to be used from the expression library. That is to say, after the scheme of adding the target picture to the expression library is applied, when the user talks in a social mode, the target picture generated according to at least one frame of image in the target video can be directly inserted by directly using the expression adding mode without starting a file manager to search from a screenshot directory, so that convenience of user operation can be remarkably improved.
It can be understood that when a user needs to insert a target picture into social speech content as an expression, besides the above scheme manually selected from the expression library, an intelligent recommendation mode can be adopted; for example, the target picture is a laugh dynamic picture of the star a, and after the target picture is identified by a content identification algorithm or manually identified, a laugh expression tag can be added to the target picture, so that when software identifies that a user inputs laugh, haha, hey and other sentences related to the laugh expression tag in social speech, the laugh dynamic picture of the star a to which the laugh expression tag is added can be automatically recommended, the user can directly confirm to add the dynamic picture, and the input efficiency of the dynamic picture is further improved.
Based on the above embodiments, those skilled in the art can know that, because the target picture generated based on the target video is stored in the expression library and the screenshot scene is communicated with the social speaking scene, the user can quickly find the target picture from the alternative expressions in the expression library during the social speaking, so that the video screenshot sharing efficiency under the social speaking scene can be remarkably improved, and the user experience is improved.
On the basis of the above technical solutions, the present disclosure also provides a number of refinement schemes as follows in order to achieve additional technical effects.
In an embodiment, at least two video frames used for generating the target dynamic picture in the step S102 may be specified by a screenshot instruction; when the method is implemented, the client side can firstly receive a screenshot instruction carrying progress information indicating the progress of the to-be-stored clip in the target video, and then generate a target dynamic picture according to at least two frames of images in the to-be-stored clip corresponding to the progress information. For example, a shortcut button for capturing the latest 3 seconds may be preset in the client interface, and a screenshot instruction indicating that the progress of the to-be-saved clip in the target video is 3 seconds before the current progress is received when a trigger operation of the shortcut button by the user is received; then, the video clip corresponding to "3 seconds before the current progress" can be used as a clip to be saved, so as to generate a target dynamic picture according to at least two frames of images in the clip.
By adopting the embodiment, a person skilled in the art can flexibly set the acquisition mode of the screenshot instruction, so that a user can flexibly select the video clip for screenshot.
In an embodiment, the progress of the segment to be saved in the target video can be indirectly indicated through a progress indication control of the target video; specifically, the progress indication control may include a control for indicating the playing progress of the target video on the software interface, and may be in a shape of a bar, a ring, a column, and the like, where the bar-shaped progress indication control is also referred to as a "progress bar"; the present disclosure does not limit the specific form of the progress indication control described above. When the method is realized, the client can respond to the triggering operation of the preset screenshot function control and display a starting point mark and an end point mark in a corresponding area of the progress indication control of the target video; the positions of the starting point mark and the end point mark are respectively used for indicating the starting point and the end point of the segment to be stored in the target video; and then, responding to the position adjustment operation of the starting point mark and/or the end point mark, adjusting the position of the starting point mark and/or the end point mark, and then generating a screenshot instruction carrying the video progress corresponding to the latest position of the starting point mark and the end point mark. It can be understood that the triggering operation on the preset screenshot function control can be operations such as clicking, long-time pressing, dragging and the like on a screenshot button on an interface; the screenshot command can be executed in response to the confirmation operation of the user or in response to a preset no-operation timer when being generated; for example, when the user does not move the start point mark and/or the end point mark for 3 seconds, a screenshot command can be triggered to be generated; the software implementation details can be designed by a person skilled in the art according to product requirements, and the disclosure does not limit the specific form of the trigger operation of the preset screenshot function control nor the specific content of the trigger mechanism for generating the screenshot instruction.
Referring to fig. 3, fig. 3 is an exemplary diagram of an interface for determining a screenshot progress, shown in an exemplary embodiment, in which a client uses a progress bar to indicate a playing progress of a target video, and after receiving a trigger operation on a preset screenshot function control, adds and displays a start point marker and an end point marker on the progress bar, where the start point marker and the end point marker may be moved by a user by dragging, and generates a screenshot instruction carrying progress information corresponding to a position of the start point marker and the end point marker on the progress bar based on the position of the start point marker and the end point marker on the progress bar after the user clicks a "confirmation" control in the diagram.
By applying the embodiment, the progress bar can intuitively indicate the playing progress of the target video, so that the movable starting point mark and the movable end point mark can more intuitively show the progress of the segment to be stored in the whole target video, and the interaction experience of a user is improved.
In another embodiment, the starting point and the ending point of the segment to be saved in the target video can be realized without depending on the progress bar; when the target video playing is realized, the client can sequentially receive a screenshot starting instruction and a screenshot stopping instruction in the playing process of the target video; the screenshot starting instruction and the screenshot stopping instruction are respectively used for indicating a starting point and an end point of the to-be-stored clip in the target video; and then, the client can generate a screenshot instruction carrying the video progress corresponding to the screenshot starting instruction and the video progress corresponding to the screenshot stopping instruction. Referring to FIG. 4, FIG. 4 is another exemplary diagram of an interface for determining the progress of a screenshot, according to an illustrative embodiment; in this example, the target video is in a playing state, and the user may press the screenshot button in the diagram when playing to the start point of the segment to be saved, and release the screenshot button in the diagram when playing to the end point of the segment to be saved, so that the client may identify the pressed and released instruction of the screenshot button as the screenshot starting instruction and the screenshot stopping instruction, respectively, and further generate the screenshot instruction carrying the video progress corresponding to the screenshot starting instruction and the video progress corresponding to the screenshot stopping instruction.

In an embodiment, the process of generating the target picture based on at least one frame of image of the target video may be implemented by an intelligent recommendation algorithm; specifically, the client may determine, in the target video, at least one segment to be saved containing preset high-value content based on a content recognition algorithm; generating alternative dynamic pictures corresponding to the fragments to be saved respectively based on at least two frames of images in the fragments to be saved; and in response to the selection operation, determining at least one alternative dynamic picture as the target dynamic picture. Referring to FIG. 5, FIG. 5 is a diagram illustrating an example of an interface for presenting alternative dynamic pictures in accordance with an illustrative embodiment; in this example, the client may present 4 candidate pictures respectively corresponding to 4 segments to be saved containing preset high-value content, and determine, as the target moving picture, candidate picture 1 and candidate picture 4 shown in the figure by receiving a selection operation of the user.
It is understood that a person skilled in the art may design the content recognition algorithm for determining the segment to be saved in which the high-value content is located, for example, an algorithm based on face recognition may be used to filter facial expressions, etc., and further enumeration and disclosure of implementation details thereof are not required in the present disclosure; moreover, the client may execute the content recognition algorithm locally in the client segment, or may send a request to the server to enable the server to execute the content recognition algorithm and return a recognition result, and the disclosure does not need to limit a specific execution subject of the content recognition algorithm.

In one embodiment, the specific storage location and the dependency relationship of the expression library can be flexibly set; for example, the expression library may be a local expression library, or an online expression library stored in the cloud, which may be a expression library bound to a user account, or a sharable expression library not bound to the user account. For example, if the intercepted emotions are stored locally and account numbers are not distinguished, that is, the emotions stored by the user a are not a local emotions library bound to the user account, and can also be accessed and used by the user b using the same device; and if the intercepted expression is stored in the cloud end, the account number is distinguished, namely, the expression library is an online expression library bound with the user account, so that the expression stored by the user A can be accessed as long as the account number of the user A is logged in no matter whether the user A switches equipment.
The effects generated by analyzing various expression libraries can be known, the local expression library is favorable for quick access and reduction of operation time delay, the online expression library is favorable for ensuring that the stored expressions are not lost when equipment is replaced, the expression library bound with a user account can be used for improving the personalization level of the expression library and meeting personal requirements, and the expression library not bound with the user account can be used for improving the universality of the expression library and enabling excellent expressions to be used by more people. Therefore, by applying the scheme, the specific storage position and the dependency relationship of the expression library can be flexibly selected, so that the method is beneficial to adapting to different product requirements and improving user experience.
In an embodiment, the target picture may further carry source information; specifically, the source information may be used to indicate source information of a corresponding target video; for example, if the target video is an original video of a certain video author, the watermark of the video author can be carried in the correspondingly generated target picture to indicate the author of the target video; for another example, if the target video is an exclusive contract video of a certain video platform, a trademark of the video platform and the like can be carried in the correspondingly generated target picture.
By applying the scheme, the requirement of a video creator or a video platform on the maintenance of the video copyright can be met, and the generated target picture can not be illegally stolen.
In an embodiment, the method may include a screenshot authority confirmation link; specifically, before the target picture is generated, whether the target video is a video for which screen capture is prohibited or not may be determined; if so, hiding the function entrance corresponding to the generated target picture and/or displaying the prompt information of the target video forbidden screenshot. For example, if a target video is an exclusive contract video of a certain video platform, the video platform expects that the target video cannot be captured within the first 24 hours of online, so that more people can directly watch the target video, the target video can be marked as a video for which capture is prohibited in the first 24 hours of online of the target video, the client can determine that the target video is the video for which capture is prohibited, and hide a capture button of the video, so that a user cannot trigger a capture function built in the client; or, the client may pop up a prompt to inform the user that the video cannot be captured currently, and so on. It is to be understood that the present disclosure is not limited to the particular form of the function entry described above, nor to the particular form of the prompt message described above.
By applying the scheme, the requirement of a video creator or a video platform on the maintenance of the video copyright can be met, and a target picture cannot be generated by a client under the condition that the target video is forbidden to capture the picture.
In an embodiment, the method may further include a sharing process of the target picture. Specifically, after the target picture is generated, a sharing control for sharing the target picture may be displayed; and responding to the triggering operation of the sharing control, and sharing the target picture to the sharing target indicated by the triggering operation. For example, the target picture may be shared in other social applications in a cross-application message manner, or the target picture may be shared with a contact in a social system of the video playing application itself, and so on. The specific form of the sharing control and the sharing target which can be selected do not need to be limited specifically.
By applying the scheme, the user can share the target picture captured from the target video more quickly, and the mobility of the video screenshot in the social relationship network is further improved.
In an embodiment, the expression library may further be configured with an expression recommendation function. Specifically, the client may add at least one picture, which is generated based on any target video and has a heat index greater than a preset threshold, to the expression library when determining that the number of pictures in the expression library is less than the preset threshold; wherein the heat index is positively correlated with the number of times the corresponding picture is saved and/or used by the user. Referring to fig. 6, fig. 6 is an exemplary diagram of an interface for presenting recommended pictures in an emoticon library, according to an exemplary embodiment; in this example, the preset threshold of the number of pictures is 3, and since the number of pictures in the current expression library is 2 and less than 3, the client adds three popular target video screenshot pictures of a recommended expression a, a recommended expression B and a recommended expression C to the expression library; whether the video screenshot picture is "hot" or not can be evaluated through the heat index; for example, the client may collect video screenshot pictures generated and shared by other users or the client, obtain a corresponding popularity index of the video screenshot pictures, and add the video screenshot pictures with a high popularity index to the expression library used by the current user.
It can be understood that the heat index of the video screenshot picture can be positively correlated with the times that the video screenshot picture is saved and/or used by the user; in this way, the pictures recommended to be added to the expression library are video screenshot pictures that are stored and/or used by the user a sufficiently high number of times. By applying the scheme, the video screenshot with high use frequency or high storage frequency can be intelligently recommended to the user as the expression under the condition that the user does not store enough video screenshots as the expression, so that the user can more conveniently use the video screenshots as the expression, the propagation of high-quality video screenshots can be promoted, and the influence of the corresponding target video is improved.
