Referring to fig. 2, in an exemplary embodiment of a video wallpaper processing method of the present application, the method includes the following steps:
step 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 files are generally output to a video playing page to be played and displayed, the video files which are output and played in the video playing page are generally obtained from a server of a platform, wherein the video files which can trigger the dynamic wallpaper setting instruction are generally video files meeting wallpaper rule, the wallpaper rule generally prescribes video duration and video quality of the video files, the video duration is generally set in a range of 3-5 seconds and corresponds to the video duration, the video quality is generally based on setting corresponding video resolution threshold, video code rate threshold, video frame number threshold and other parameter threshold which influence video playing and displaying quality, and the video quality of the video files is checked to screen the dynamic video wallpaper which is rendered by the video files with better playing and displaying quality, so that the look and feel 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-capable rule is endowed with a wallpaper-capable identifier, namely, a dynamic wallpaper setting instruction which can be acted on the video file with the wallpaper-capable identifier is triggered; executing and checking whether the video file meets the wallpaper rule or not, wherein an executing end of the wallpaper video file can be a terminal device of a platform user or a service server of the platform, if the executing end is the terminal device, the terminal device checks whether the video file meets the wallpaper rule or not after acquiring the video file from the server of the platform, and if the video file meets the wallpaper rule, the corresponding wallpaper identifier of the video file is given; if the executive party is a server, the server checks whether each video file provided by the executive party meets the wallpaper-capable rule, endows each video file which meets the wallpaper-capable rule with corresponding wallpaper-capable identifiers, and pushes the video file and the wallpaper-capable identifiers to the terminal equipment together when pushing the video file to the terminal equipment of a 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-capable identifiers provided by the terminal equipment after receiving the video file.
When the video file with the set dynamic wallpaper is played in the video playing page, the corresponding set dynamic wallpaper control is displayed in the video playing page, specifically, please refer to fig. 3 and fig. 4, the video file played in the video playing page shown in fig. 3 meets the wallpaper rule, the set dynamic wallpaper control S301 acting on the video file is displayed in the video playing page, if the video file does not meet the wallpaper rule, the video playing page of the video file when playing and displaying is the video playing page as shown in fig. 4, and the set dynamic wallpaper control S301 shown in fig. 3 is not included in fig. 4; the user of the terminal device in the video playing page shown in fig. 3 sets the dynamic wallpaper control S301 through touch control, and triggers the dynamic wallpaper setting instruction acting on the video file currently played in fig. 3.
After responding to the dynamic wallpaper setting instruction acted on the video file currently played by the video application program, the video application program playing the video file enables a dynamic wallpaper rendering service which is controlled to render 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 not the starting service, the system wallpaper service is started, and after binding the dynamic wallpaper rendering service with the system wallpaper service, the dynamic wallpaper rendering service is started; the video application program and the dynamic wallpaper rendering service are mutually independent, the two parties are respectively and independently operated in the terminal equipment of the user, the operation condition of the other party is not influenced when any party is in an un-started state, and the video application program and the dynamic wallpaper rendering service are mutually independent, so that after the video application program stops operating at the terminal equipment, the dynamic wallpaper rendering service bound with the system wallpaper service can still output the 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 the system wallpaper of the system wallpaper service of the terminal equipment; specific embodiments of the dynamic wallpaper rendering service will be described in the following steps, and the present application is not repeated.
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 display;
after the dynamic wallpaper rendering service is started, a dynamic wallpaper rendering instruction containing the video file is pushed to the dynamic wallpaper rendering service, so that the dynamic wallpaper rendering service responds to the dynamic wallpaper rendering instruction, the file acquisition address contained in the instruction is acquired, the video file is acquired through the file acquisition address, the video file is further rendered into the dynamic video wallpaper, and the dynamic video wallpaper is output to a wallpaper preview window to be displayed.
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 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 position 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 position.
After the dynamic wallpaper rendering service acquires the video file, checking whether the video aspect ratio of the video file meets the rule to be cut, and if so, performing video proportion cutting processing on the video file; since the terminal device for playing the video file is generally a mobile terminal device, such as a mobile phone terminal or a tablet computer terminal, the aspect ratio of the mobile phone terminal screen is generally 9:16, the aspect ratio of the tablet screen is generally 16:10, and the video aspect ratio of the output video file is in accordance with 9 of the aspect ratio of the mobile phone: 16, the video aspect ratio of the partial video file is 4:3 or 16:9, therefore, if the current terminal is a mobile phone terminal and the aspect ratio of its screen is 9:16, the video aspect ratio of the output video file is 4:3, cutting the aspect ratio of the video file to be 9:16 which accords with the aspect ratio of the current terminal, so that the dynamic video wallpaper rendered by 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 proportion, the display effect of the dynamic video wallpaper is optimized, and the look and feel of the dynamic video wallpaper is improved; in the specific implementation manner of the to-be-cut rule, the dynamic rendering service determines an aspect ratio of the current device screen, calculates a difference value between the aspect ratio of the current device screen and the video aspect ratio of the video file, determines whether the difference value does not exceed a preset aspect ratio threshold, if not, does not perform video proportional cutting processing on the video file, and if yes, performs video proportional cutting processing on the video file, wherein the to-be-cut rule allows a certain error between the aspect ratio of the device screen and the video aspect ratio of the video file, and the value of the error is specified by the aspect ratio threshold instead of processing all video files with different aspect ratios between the aspect ratio of the video file and the aspect ratio of the device screen, so as to ensure that the video file renders a complete video picture with the video file in the obtained dynamic video wallpaper, save computing resources of the device, and improve the rendering speed of the dynamic video wallpaper.
When the wallpaper rendering service processes a video file of which the aspect ratio is required to be cut, a video decoder is called to decode the video file to generate a video frame data set, a video wide-high cutter is called to cut the original aspect ratio of all video frames contained in the video frame data set into target aspect ratio examples, video frames with the target aspect ratio examples are cached in a video frame cache area, and then a video encoder is called to encode all video frames in the video frame cache area into a video file, wherein the video aspect ratio examples of the video file are the target aspect ratio examples; when the video frame clipping process is performed, the video wide-height clipping device initializes a visual range of a texture coordinate system, determines interface aspect ratio data of a current terminal, calculates a target aspect ratio case and an offset value corresponding to the video frame according to the interface aspect ratio data, converts the target aspect ratio case and the offset value into the texture coordinate range in the visual range, and draws the current video frame to the texture coordinate range, so as to clip the original aspect ratio case of the current video frame into the target aspect ratio case.
The dynamic wallpaper rendering service renders a video file into the dynamic video wallpaper, and draws the dynamic video wallpaper into a wallpaper preview page for display; the dynamic video wallpaper is a video file which is rendered and converted into wallpaper suitable for being used as a terminal device through the dynamic wallpaper rendering service, although the video file is basically the video file, when the dynamic video wallpaper is more suitable for being used as the wallpaper of the terminal device, besides the aspect ratio embodiment clipping is carried out so that the video file can be more suitable for being output and played by the aspect ratio embodiment of the terminal device, the video file is generally subjected to video resolution, video code rate, video frame number and file format optimization processing to be rendered into the dynamic video wallpaper to be output and played by being used as the wallpaper of the terminal device, and the video resolution, the video code rate and the video frame number are optimized to prevent the video resolution, the video code rate and the video frame number from being excessively high, so that the system of the terminal device cannot be smoothly operated, and the file format of the video file is modified into the format supported by the wallpaper service playing video of the terminal device, so that the obtained dynamic video wallpaper can be effectively output as the system wallpaper to be displayed in a graphical user interface of the terminal device.
In an embodiment, in the dynamic wallpaper rendering service, a video aspect ratio, a video resolution, a video code rate and a video frame number of a video file can be opened to a user at a terminal device for customizing, so that the user can customize a rendering requirement of the video file according to needs, specifically, the dynamic wallpaper rendering service generates a rendering custom editing window for generating the video file to be rendered into the dynamic video wallpaper currently to a graphical user interface for displaying, related controls for customizing the video aspect ratio, the video resolution, the video code rate and the video frame number of the video file are displayed in the rendering custom editing window for the user to perform custom editing, and the dynamic wallpaper rendering service renders the video file into corresponding dynamic video wallpaper according to the video aspect ratio, the video resolution, the video code rate and the video frame number edited in each control and outputs the corresponding dynamic video wallpaper to the wallpaper preview window for displaying.
Referring to fig. 5, the wallpaper preview window is configured to output the dynamic video wallpaper for a user at a current terminal to browse a display effect of the dynamic video wallpaper, where 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 is generally WallpaperService, and since the dynamic wallpaper rendering service is bound with the system wallpaper service, the dynamic wallpaper rendering service may generate the wallpaper preview window through an interface provided by WallpaperService, so as to output the rendered dynamic video wallpaper to the wallpaper preview window for display and play; referring to fig. 5, after the video file is rendered into the dynamic video wallpaper by the dynamic wallpaper rendering service, the dynamic video wallpaper is output to the wallpaper preview window shown in fig. 5 for display and play.
After the wallpaper rendering service outputs the dynamic video wallpaper to the wallpaper preview window for display, the wallpaper rendering service responds to a wallpaper application event acting on the wallpaper preview window to respond to the wallpaper application event of the wallpaper preview window to push a corresponding wallpaper application result of the event to a video application, specifically, please refer to fig. 5, a user at a current terminal can set the displayed wallpaper preview window to display the wallpaper application event which is successful in playing the dynamic video wallpaper as the system wallpaper of the current terminal through a wallpaper setting control S501 shown in fig. 5, the wallpaper rendering service generates a wallpaper application result which is characterized in that the wallpaper application is successful and pushes the wallpaper application result to a video application program which is played the video file in response to the event, and when the user closes the displayed wallpaper preview window and cancels the system wallpaper which is set the dynamic video wallpaper as the current terminal through a cancellation control S502 shown in fig. 5, the wallpaper application event which is triggered to cancel the wallpaper application is pushed to the video application program in response to the event.
In an embodiment, after the wallpaper rendering service renders 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 stores the dynamic video wallpaper and a unique identifier of a video file to which the dynamic video wallpaper belongs in a wallpaper library, when the wallpaper rendering service in other terminal equipment needs to render the dynamic video wallpaper of the video file, a wallpaper obtaining instruction can be pushed to the server, the server responds to the instruction to obtain the dynamic video wallpaper from the wallpaper library and push the dynamic video wallpaper to a wallpaper rendering service of the terminal equipment, so that the wallpaper rendering service can obtain the dynamic video wallpaper of the video file without rendering and output the dynamic video wallpaper to a wallpaper preview window for display, thereby saving computing resources of the terminal equipment and improving use experience of a user.
And S13, acquiring a wallpaper application result pushed by the dynamic wallpaper rendering service, and outputting the wallpaper application result to the current page.
The dynamic wallpaper rendering service responds to the wallpaper application event in the wallpaper preview window to generate a corresponding wallpaper application result according to the wallpaper application event and push the corresponding 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, please refer 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 indicating that the wallpaper application is successful and push the wallpaper application result to the video application program, and 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 indicating that the wallpaper application is cancelled and push 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 by different wallpaper application results, specifically, please refer to fig. 6 and fig. 7, the notification file displayed in the wallpaper application result notification window S601 shown in fig. 6 is a wallpaper application result representing that the wallpaper application is successful, and the notification file displayed in the wallpaper application result notification window S701 shown in fig. 7 is a wallpaper application result representing that the wallpaper application is cancelled, wherein the user may share the dynamic video wallpaper rendered by the dynamic wallpaper rendering service to other platform users in the platform through the shown wallpaper application result notification window S601 or S701.
Different from the existing dynamic wallpaper with lower quality generated by performing system wallpaper setting by self screenshot of a platform user or performing screen recording by means of a third party application program, the method uses the corresponding dynamic video wallpaper generated by rendering the video file played in the video application program as the system wallpaper of the terminal equipment, and provides the platform user with a dynamic video wallpaper generating function to meet the personalized requirements of the platform user, and improves the exposure of the video content of the platform, wherein the video application program and the dynamic wallpaper rendering service are mutually independent, the two parties respectively independently operate in the terminal equipment of the user, and neither party is in an uninitiated state, so that when the video application program stops operating in the terminal equipment, the dynamic wallpaper rendering service bound with the system wallpaper service can still output the dynamic video wallpaper rendered by the video application program to the graphical user interface of the terminal equipment for playing and displaying, the dynamic video wallpaper serving as the system wallpaper of the terminal equipment, so that the platform user can display the dynamic video wallpaper in the system desktop without opening the video application program, the video wallpaper and the system wallpaper serving the system desktop have higher adaptability, and the user can smoothly operate the system wallpaper without occupying the terminal equipment to operate the system wallpaper, and the system wallpaper resources can be smoothly set up and operate the system wallpaper.
