Referring to fig. 2, a video wallpaper processing method according to the present application, in an exemplary embodiment, includes the following steps:
s11, responding to a dynamic wallpaper setting instruction of a currently played video file, and controlling a dynamic wallpaper rendering service to be in a starting state;
the video file is generally output to a video playing page to be played and displayed, the video file output and played in the video playing page is generally obtained from a server of a platform, wherein the video file capable of triggering the setting of the dynamic wallpaper instruction is generally a video file meeting a wallpaper rule, the wallpaper rule generally specifies the video duration and the video quality of the video file, the video duration is generally set within a range of 3-5 seconds, correspondingly, the video quality is generally based on setting a corresponding video resolution threshold, a video code rate threshold, a video frame number threshold and other parameter thresholds which influence video playing display quality, and by checking the video quality of the video file, the dynamic video wallpaper rendered by the video file with better playing display quality is screened, and the impression of the dynamic video wallpaper is improved; the video file with the video duration and the video quality being more than or equal to the wallpaper enabling rule is endowed with a wallpaper enabling identification, namely the video file with the wallpaper enabling identification can be triggered to act on a dynamic wallpaper setting instruction; the execution end for executing and verifying whether the video file meets the wallpaper-enabled video file can be a terminal device of a platform user or a business server of the platform, if the execution party is the terminal device, after the terminal device acquires the video file from the server of the platform, whether the video file meets the wallpaper-enabled rule or not is verified, and if the execution party is the terminal device, a wallpaper-enabled identifier corresponding to the video file is given; if the executive party is the server, the server verifies whether each video file of the executive party meets the wallpaper rule respectively, endows a wallpaper identification corresponding to each video file meeting the wallpaper rule, and pushes the video file and the wallpaper identification to the terminal equipment when the video file is pushed to the terminal equipment of the platform user, so that the terminal equipment can determine the video file as the video file capable of triggering the dynamic wallpaper setting instruction through the wallpaper identification of the terminal equipment after receiving the video file.
Specifically, referring to fig. 3 and 4, when a video file with the dynamic wallpaper set is played in a video playing page, the video file played in the video playing page shown in fig. 3 satisfies the wallpaper rule, the set dynamic wallpaper control S301 acting on the video file is displayed in the video playing page shown in fig. 3, if the video file does not satisfy the wallpaper rule, the video playing page of the video file during playing and displaying is the video playing page shown in fig. 4, and the set dynamic wallpaper control S301 shown in fig. 3 is not included in fig. 4; a user of the terminal device on the video playing page shown in fig. 3 triggers the dynamic wallpaper setting instruction acting on the video file currently playing in fig. 3 by touching the dynamic wallpaper setting control S301.
After responding to the set dynamic wallpaper instruction acting on the currently played video file, the video application program playing the video file controls the dynamic wallpaper rendering service for rendering the corresponding dynamic video wallpaper for the video file to be in a starting state, specifically, the video application program inquires the service state of the dynamic wallpaper rendering service, when the service state is the service not started, the system wallpaper service is started, and after the dynamic wallpaper rendering service is bound with the system wallpaper service, the dynamic wallpaper rendering service is started; the video application program and the dynamic wallpaper rendering service are independent of each other, the video application program and the dynamic wallpaper rendering service are operated in terminal equipment of a user independently, and neither one of the video application program and the dynamic wallpaper rendering service affects the operation condition of the other one of the video application program and the dynamic wallpaper rendering service, so that after the video application program stops operating in the terminal equipment, the dynamic wallpaper rendering service bound with the system wallpaper service can still output dynamic video wallpaper rendered by the video application program to a graphical user interface of the terminal equipment for playing and displaying, and the dynamic video wallpaper is used as system wallpaper of the system wallpaper service of the terminal equipment; the specific implementation of the dynamic wallpaper rendering service will be described in the following steps, which is not repeated herein.
Step S12, pushing the file acquisition address of the video file to the dynamic wallpaper rendering service, driving the dynamic wallpaper rendering service to render the video file acquired by the file acquisition address into dynamic video wallpaper, and outputting the dynamic video wallpaper to a wallpaper preview window for displaying;
and after the dynamic wallpaper rendering service is started, pushing a dynamic wallpaper rendering instruction containing the video file to the dynamic wallpaper rendering service so that the dynamic wallpaper rendering service responds to the dynamic wallpaper rendering instruction, acquires the file acquisition address contained in the instruction, acquires the video file through the file acquisition address, renders the video file into the dynamic video wallpaper, and outputs the dynamic video wallpaper to a wallpaper preview window for display.
The file acquisition address generally refers to a file network downloading address of the video file, and after the dynamic wallpaper rendering service acquires the file acquisition address, the video file is downloaded from a server for storing the video file through the file acquisition address; correspondingly, the file acquisition address can also be a local storage address, and the dynamic wallpaper rendering service queries a local storage location corresponding to the file acquisition address in the current device through the file acquisition address so as to acquire the video file from the local storage location.
After the dynamic wallpaper rendering service acquires the video file, checking whether the high ratio of the video bandwidth of the video file meets the requirement of cutting rule, and if so, performing video ratio cutting processing on the video file; because the terminal device for playing the video file is generally a mobile terminal device, such as a mobile phone terminal or a tablet terminal, the width-to-height ratio of the screen of the mobile phone terminal is generally 9: the width-to-height ratio of a tablet computer screen is generally 16:10, and the video aspect ratio of the video file output for play is in addition to the aspect ratio of 9: in addition to 16, the high ratio of the video bandwidth of a part of the video files is 4:3 or 16:9, therefore, if the current terminal is a mobile phone terminal and the aspect ratio of the screen is 9: 3, the width-to-height ratio of the video file needs to be cut to be 9, 16, which meets the width-to-height ratio of the current terminal, so that the dynamic video wallpaper obtained by rendering the video file can be output to a graphical user interface of the current terminal for playing and displaying under the condition of not stretching the size ratio, the display effect of the dynamic video wallpaper is optimized, and the appearance of the dynamic video wallpaper is improved; in a specific implementation manner of the rule to be clipped, the dynamic rendering service determines a width-to-height ratio of a current device screen, calculates a difference between the width-to-height ratio of the current device screen and a video width-to-height ratio of the video file, determines whether the difference does not exceed a preset width-to-height ratio threshold, if the difference does not exceed the preset width-to-height ratio threshold, does not perform video scale clipping on the video file, and if the difference exceeds the preset width-to-height ratio threshold, performs video scale clipping on the video file.
When the wallpaper rendering service processes a video file with a high width and a high proportion to be cut, a video decoder is called to decode the video file to generate a video frame data set, a video width and height cutter is called to respectively cut the original width and height proportions of all video frames in the video frame data set into a target width and height proportion, video frames with the target width and high proportion are cached in a video frame cache region, a video encoder is called to encode all the video frames in the video frame cache region into a video file, and the video width and height proportion of the video file is the target width and height proportion; when the video frame is cut, the video width height clipper initializes the visual range of a texture coordinate system, determines the interface width height ratio data of the current terminal, calculates the target width height ratio and the offset value corresponding to the video frame according to the interface width height ratio data, further converts the target width height ratio and the offset value into the texture coordinate range in the visual range, draws the current video frame to the texture coordinate range, and clips the original width height ratio of the current video frame into the target width height ratio.
The dynamic wallpaper rendering service renders the video file into the dynamic video wallpaper, and draws the dynamic video wallpaper into a wallpaper preview page to be displayed; the dynamic video wallpaper is a video file suitable for being used as wallpaper of terminal equipment through rendering and converting the video file into the dynamic video wallpaper through the dynamic wallpaper rendering service, although both are video files essentially, when the dynamic video wallpaper is more suitable for being used as the wallpaper of the terminal equipment, in addition to the clipping with the high width and the high proportion, the video file can be more suitable for being output and played in the high screen width and the high proportion of the terminal equipment, the dynamic video wallpaper is rendered into the dynamic video wallpaper for being output and played as the wallpaper of the terminal equipment through optimizing the video resolution, the video bitrate, the video frame number and the file format, and the dynamic video wallpaper generated through rendering can be effectively output to a graphical user interface of the terminal equipment as the wallpaper of the terminal equipment to be displayed through optimizing the video resolution, the video bitrate, the video frame number and the video frame number to prevent the dynamic video wallpaper from occupying the operation memory of the terminal equipment due to the overhigh video resolution, video bitrate and video frame number, so that the system of the terminal equipment cannot run smoothly.
In one embodiment, the video width-to-height ratio, the video resolution, the video bitrate, and the video frame number of a video file in the dynamic wallpaper rendering service may be opened to a user at a terminal device for customizing, so that the user can customize the rendering requirement of the video file as needed, specifically, the dynamic wallpaper rendering service generates a rendering customized editing window for generating the video file to be rendered into dynamic video wallpaper, and displays the rendering customized editing window into a graphical user interface, the rendering customized editing window displays a control component for customizing the video width-to-height ratio, the video resolution, the video bitrate, and the video frame number of the video file for the user to perform customized editing, and the dynamic wallpaper rendering service renders the video file into a corresponding dynamic video wallpaper for display into the preview window according to the video width-to-height ratio, the video resolution, the video bitrate, and the video frame number edited in each control component.
Referring to fig. 5, the wallpaper preview window is used for outputting the dynamic video wallpaper for a user at a current terminal to view a display effect of the dynamic video wallpaper, the wallpaper preview window is generally provided by a system wallpaper service in an operating system of the current terminal, for example, for an Android (Android) operating system, a system wallpaper service provided by the wallpaper preview window is generally a WallpaperService, and since the dynamic wallpaper rendering service is bound to the system wallpaper service, the dynamic wallpaper rendering service can generate the wallpaper preview window through an interface provided by the WallpaperService, so as to output a dynamic wallpaper video obtained by rendering to the wallpaper preview window for display and play; referring to fig. 5, after the dynamic wallpaper rendering service renders the video file into the dynamic video wallpaper, the dynamic video wallpaper is output to the wallpaper preview window shown in fig. 5 for display and playing.
Specifically, referring to fig. 5, when a user at a current terminal can set a displayed dynamic video wallpaper in the wallpaper preview window to a system wallpaper of the current terminal through a wallpaper setting control S501 shown in fig. 5, the wallpaper application event that the wallpaper application succeeds is triggered, the wallpaper rendering service generates a wallpaper application result that is characterized by the successful wallpaper application and pushes the wallpaper application result to a video application program that plays the video file, when the user closes the wallpaper preview window through a cancel control S502 shown in fig. 5 and cancels the setting of the dynamic video wallpaper to the system wallpaper of the current terminal, the wallpaper rendering service generates a wallpaper application result that is characterized by the successful wallpaper application and pushes the wallpaper application result to the video application program that plays the video file, and when the user closes the wallpaper preview window through a cancel control S502 shown in fig. 5 and cancels the setting of the dynamic video wallpaper to the system wallpaper of the current terminal, the wallpaper application rendering service generates a wallpaper application result that is characterized by the cancel application and pushes the wallpaper application result to the video application program.
In an embodiment, after the wallpaper rendering service renders and generates the dynamic video wallpaper, the dynamic video wallpaper is pushed to a server of a platform corresponding to the video application program, so that the server correspondingly stores the dynamic video wallpaper and a unique identifier of a video file to which the dynamic video wallpaper belongs in a wallpaper library, so that when the wallpaper rendering service in other terminal devices needs to render the dynamic video wallpaper of the video file, a wallpaper acquisition instruction can be pushed to the server, and the server responds to the instruction to acquire the dynamic video wallpaper from the wallpaper library and pushes the dynamic video wallpaper to a wallpaper rendering service of the terminal device, so that the wallpaper rendering service can acquire the dynamic video wallpaper of the video file without rendering and output the dynamic video wallpaper to the wallpaper preview window for display, thereby saving computing resources of the terminal device and improving the use experience of users.
And S13, acquiring a wallpaper application result pushed by the dynamic wallpaper rendering service, and outputting the wallpaper application result to a current page.
The dynamic wallpaper rendering service responds to a wallpaper application event in the wallpaper preview window, generates a corresponding wallpaper application result according to the wallpaper application event and pushes the wallpaper application result to the video application program, the wallpaper application event is divided into a wallpaper application success event and a wallpaper cancellation application event, specifically, referring to fig. 5, a wallpaper setting control S501 shown in fig. 5 can trigger the wallpaper application success event, the dynamic wallpaper rendering service responds to the event to generate a wallpaper application result representing the successful wallpaper application and pushes the wallpaper application result to the video application program, correspondingly, a cancellation control S502 shown in fig. 5 can trigger the wallpaper cancellation application event, and the dynamic wallpaper rendering service responds to the event to generate a wallpaper application result representing the wallpaper cancellation application and pushes the wallpaper application result to the video application program.
After receiving the wallpaper application result pushed by the dynamic wallpaper rendering service, outputting the wallpaper application result to a current page where the video file is currently played for display, and displaying different notification texts in the current page for the different wallpaper application results, specifically, referring to fig. 6 and 7, a notification file displayed in a wallpaper application result notification window S601 shown in fig. 6 is a wallpaper application result representing that wallpaper application is successful, and a notification file displayed in a wallpaper application result notification window S701 shown in fig. 7 is a wallpaper application result representing that wallpaper application is cancelled, where a user may share the dynamic video wallpaper rendered by the dynamic wallpaper rendering service to other platform users in the platform through the illustrated wallpaper application result notification window S601 or S701.
The method is different from the existing dynamic wallpaper which is generated by performing system wallpaper setting on a screenshot of a platform user or performing screen recording by means of a third-party application program and has low quality, the method is characterized in that a corresponding dynamic video wallpaper is generated by rendering a video file played in a video application program and is used as the system wallpaper of the terminal device, the dynamic video wallpaper generation function is provided for the platform user, the personalized requirement of the platform user is met, and the exposure degree of the video content of the platform is improved, wherein the video application program and the dynamic wallpaper rendering service are independent from each other, the video application program and the dynamic wallpaper rendering service are independently operated in the terminal device of the user, the operation condition of the other party is not influenced when either party is in an unactivated state, so that after the video application program stops operating in the terminal device, the dynamic wallpaper rendering service bound with the system wallpaper service can still output the rendered dynamic video wallpaper to be played and displayed in a graphical user interface of the terminal device, the dynamic video wallpaper is used as the system wallpaper of the system wallpaper service of the terminal device, the platform user can display the dynamic video wallpaper in a system wallpaper without starting the video application program to ensure that the dynamic wallpaper of the terminal device can be smoothly browsed by the system wallpaper resources.
According to another embodiment of the present application, referring to fig. 8, controlling a dynamic wallpaper rendering service in a startup state includes the following steps:
step S111, inquiring the service state of the dynamic wallpaper rendering service;
