[0002] When playing a wallpaper video, you may only need to play a section of the wallpaper video, and you do not need to play the entire wallpaper video. When playing, jump to the start of the playback section to play. In order to avoid freezes during playback, the video after the current playback time point will be pre-decoded and cached when playing the video. Since only one section of the wallpaper video needs to be played, the content of the pre-decoded cache may exceed the playback section, that is, the decoder also decodes the video outside the playback section that does not need to be played, which increases the power consumption of the wallpaper video when playing and the memory occupied by the wallpaper application. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a wallpaper video playback method, device, electronic device and storage medium, which can solve the problem of high power consumption when playing wallpaper videos.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0023] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0024] The wallpaper video playback method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, this embodiment introduces a wallpaper video playing method, which includes steps S1100-S1300.

[0026] S1100: Generate multiple video slice files based on the wallpaper video.

[0027] Wallpaper videos can be played when the desktop is displayed, and wallpaper videos can also be played in the lock screen interface. Wallpaper videos can be video files in MP4 format or in other formats. Video slice files can be video files in TS format. Video slice files correspond to different stages of wallpaper videos. For example, for a wallpaper video with a duration of three seconds, three video slice files can be generated, the first video slice file corresponds to the first second of the wallpaper video, the second video slice file corresponds to the second second of the wallpaper video, and the third video slice file corresponds to the third second of the wallpaper video. The number of video slice files can be determined based on actual business needs, and this embodiment does not limit this.

[0028] S1200: Generate an index file corresponding to each playback interval according to the multiple playback intervals of the wallpaper video and the multiple video slice files, each of the index files including an identifier of at least one video slice file, and the at least one video slice file is a file among the multiple video slice files for playing in the corresponding playback interval.

[0029] One video slice file can be played in one playback interval. Multiple video slice files can also be played in one playback interval. The playback interval can be determined according to specific business logic. For example, the video slice files include a first video slice file, a second video slice file, and a third video slice file. When the desktop is displayed, it corresponds to the first playback interval, and the first video slice file and the second video slice file are played in the first playback interval. When the lock screen interface is displayed, it corresponds to the second playback interval, and the third video slice file is played in the second playback interval.

[0030] Each playback interval corresponds to an index file, and the index file can be a streaming media file in m3u8 format. The index file includes the identifier of the video slice file played in the corresponding playback interval. For example, if the first video slice file and the second video slice file are played in the first playback interval, the identifier of the first video slice file and the identifier of the second video slice file are stored in the index file corresponding to the first playback interval. The identifier of the video slice file can be the storage path of the video slice file.

[0031] S1300: Play at least one video slice file according to an identifier of at least one video slice file included in an index file corresponding to a to-be-played interval, where the to-be-played interval is any one of the multiple play intervals.

[0032] The interval to be played can be any one of the multiple playback intervals of the wallpaper video. The interval to be played is determined according to actual needs. For example, the wallpaper video has a first playback interval and a second playback interval. When the desktop is displayed, the interval to be played is the first playback interval. When the lock screen interface is displayed, the interval to be played is the second playback interval. Query the corresponding index file according to the interval to be played. Obtain the identifier of the video slice file from the index file corresponding to the interval to be played. Play the video slice file according to the identifier of the video slice file included in the index file corresponding to the interval to be played. For example, when the index file corresponding to the interval to be played includes the identifier of the first video slice file and the identifier of the second video slice file, play the first video slice file and the second video slice file.

[0033] In this embodiment, multiple video slice files are generated according to the wallpaper video, and a corresponding index file is generated for each playback interval of the wallpaper video. The identifier of the video slice file used to play in the corresponding playback interval is stored in the index file. When playing, only the video slice files in the playback interval need to be decoded, and the videos outside the playback interval do not need to be decoded, which reduces the power consumption when the wallpaper video is played and the memory occupied by the wallpaper application. In addition, there is no need to jump during playback, which avoids the freeze during the jump and ensures the fast display of the first frame.

[0034] In this embodiment, step S1100 includes steps S1110-S1140.

[0035] S1110: According to a plurality of video stages corresponding to the wallpaper video, an image frame corresponding to each video stage is acquired, wherein a playback interval includes at least one video stage.

[0036] Wallpaper video includes multiple video stages. You can set the number of video stages included in the wallpaper video according to business needs. Figure 2 As shown, the wallpaper video may include three video stages, and the three video stages of the wallpaper video are s1, s2, and s3 in chronological order.

[0037] A playback interval may include one video stage, and a playback interval may also include multiple video stages. Multiple video stages within a playback interval may be continuous. For example, for three video stages s1, s2, and s3, there may be six corresponding playback intervals, namely s1, s2, s3, s1s2, s2s3, and s1s2s3. In playback interval s1, only video stage s1 is played. In playback interval s1s2, video stage s1 and video stage s2 are played. In playback interval s1s2s3, video stage s1, video stage s2, and video stage s3 are played.

[0038] Each video stage corresponds to multiple image frames. The image frames corresponding to each video stage can be output using rendering software. For example, a wallpaper video includes three video stages, the wallpaper video includes 720 image frames, and each video stage includes 240 image frames. The 720 image frames included in the wallpaper video are numbered img001-img720. The image frames corresponding to the first video stage s1 are numbered img001-img240. The image frames corresponding to the second video stage s2 are numbered img241-img480. The image frames corresponding to the third video stage s3 are numbered img481-img720.

[0039] S1120: Generate a front video slice file corresponding to the video stage according to first N image frames among the image frames corresponding to the video stage and a first frame rate, where N is a positive integer.

[0040] The first video segment is synthesized according to the first N image frames in the image frames corresponding to each video stage. The frame rate of the first video segment is consistent with the frame rate of the wallpaper video. The first video segment can be a video file in mp4 format, and the corresponding first video segment slice file in ts format can be generated according to the first video segment. The duration of the first video segment is determined according to the first frame rate and the number N. For example, the first video segment includes 180 image frames, and the first frame rate is 120fps, then the duration of the first video segment is 1.5 seconds.

[0041] In an example, for the three video stages of the wallpaper video, each video stage includes 240 image frames, and the corresponding front video is synthesized according to the first 180 image frames of each video stage. The image frames of the front video corresponding to the first video stage s1 are numbered img001-img180, the image frames of the front video corresponding to the second video stage s2 are numbered img241-img420, and the image frames of the front video corresponding to the third video stage s3 are numbered img481-img660. The front videos corresponding to the three video stages can be named s1_front.mp4, s2_front.mp4, and s3_front.mp4, respectively. The front video slice files corresponding to the three video stages can be named s1_front.ts, s2_front.ts, and s3_front.ts, respectively.

[0042] S1130: Generate a latter video slice file corresponding to the video stage according to the last M image frames among the image frames corresponding to the video stage and the first frame rate, where M is a positive integer, and the number of image frames corresponding to the video stage is the sum of N and M.

[0043] The latter video is synthesized according to the last M image frames in the image frames corresponding to each video stage. The frame rate of the latter video is the same as that of the former video. The latter video can be a video file in mp4 format, and the corresponding latter video slice file in ts format can be generated according to the latter video. The number of image frames corresponding to the video stage is the sum of the number of image frames corresponding to the former video and the number of image frames corresponding to the latter video. For example, a video stage includes 240 image frames, the former video includes the first 180 image frames, and the latter video includes the last 60 image frames. The frame rate of the latter video is 120fps, and the duration of the latter video is 0.5 seconds.

[0044] In one example, for the three video stages of the wallpaper video, the corresponding back-end video is synthesized according to the last 60 image frames of each video stage. The image frames of the back-end video corresponding to the first video stage s1 are numbered img181-img240, the image frames of the back-end video corresponding to the second video stage s2 are numbered img421-img480, and the image frames of the back-end video corresponding to the third video stage s3 are numbered img661-img720. The back-end videos corresponding to the three video stages can be named s1_back.mp4, s2_back.mp4, and s3_back.mp4, respectively. The back-end video slice files corresponding to the three video stages can be named s1_back.ts, s2_back.ts, and s3_back.ts, respectively.

[0045] S1140: Generate a rear-end slow-stop video slice file corresponding to the video stage according to the last M image frames in the image frames corresponding to the video stage and a second frame rate, wherein the second frame rate is lower than the first frame rate.

[0046] The image frames of the slow-stop video are the same as those of the video at the end. If the frame rate of the slow-stop video is lower than that of the video at the end, the duration of the slow-stop video is longer than that of the video at the end. For example, if the frame rate of the video at the end is 120fps and the frame rate of the slow-stop video is 60fps, the video at the end includes 60 image frames, the duration of the slow-stop video is 1 second, and the duration of the video at the end is 0.5 seconds. According to the slow-stop video at the end, the corresponding ts format video slice file can be generated.

[0047] In one example, for the three video stages of the wallpaper video, the corresponding back-end slow-stop videos are synthesized according to the last 60 image frames of each video stage. The back-end slow-stop videos corresponding to the three video stages can be named s1_backslow.mp4, s2_backslow.mp4, and s3_backslow.mp4, respectively. The back-end slow-stop video slice files corresponding to the three video stages can be named s1_backslow.ts, s2_backslow.ts, and s3_backslow.ts, respectively.

[0048] In this embodiment, the image frames of the rear slow-stop video are the same as the image frames of the rear video, and the frame rate of the rear slow-stop video is less than the frame rate of the rear video, so that the duration of the rear slow-stop video is greater than the duration of the rear video, achieving a slow-stop effect. And for each video stage, a front video slice file, a rear video slice file, and a rear slow-stop video slice file are generated to ensure that the slow-stop effect can be achieved for any playback interval. In addition, the present invention can also reduce the difficulty of developing such video wallpapers. During the development process, there is no need to control the stage interval of video playback, nor is there any need to control the video playback speed or use video connection to process the slow-stop effect.

[0049] In this embodiment, the step S1200 includes S1210-S1220.

[0050] S1210: Obtain the identifier of at least one video slice file corresponding to the playback interval, wherein the identifier includes the identifier of the front video slice files of the K video stages corresponding to the playback interval, the identifier of the rear video slice files of the first K-1 video stages, and the identifier of the rear slow-stop video slice file of the last video stage among the K video stages, where K is a positive integer.

[0051] When the playback interval includes only one video stage, K takes the value of 1, and the video slice files corresponding to the playback interval include the front video slice file and the back slow-stop video slice file of the video stage. For example, the playback interval includes only the video stage s1, and the video slice files corresponding to the playback interval include the front video slice file s1_front.ts of the video stage s1 and the back slow-stop video slice file s1_backslow.ts of the video stage s1.

[0052] In the case where the playback interval includes multiple video stages, the value of K is greater than or equal to 2. The video slice files corresponding to the playback interval include the front video slice files of K video stages, the back video slice files of the first K-1 video stages, and the back slow-stop video slice file of the Kth video stage. The Kth video stage is the last video stage of the playback interval. For example, the playback interval s1s2 includes 2 video stages, namely video stage s1 and video stage s2. The last video stage of the playback interval s1s2 is video stage s2. The video slice files corresponding to the playback interval s1s2 include the front video slice file s1_front.ts of video stage s1, the back video slice file s1_back.ts of video stage s1, the front video slice file s2_front.ts of video stage s2, and the back slow-stop video slice file s2_backslow.ts of video stage s2. Exemplarily, the playback interval s1s2s3 includes 3 video stages, namely video stage s1, video stage s2, and video stage s3. The last video stage of the playback interval s1s2s3 is the video stage s3. The video slice files corresponding to the playback interval s1s2s3 include the front video slice file s1_front.ts of the video stage s1, the back video slice file s1_back.ts of the video stage s1, the front video slice file s2_front.ts of the video stage s2, the back video slice file s2_back.ts of the video stage s2, the front video slice file s3_front.ts of the video stage s3, and the back slow-stop video slice file s3_backslow.ts of the video stage s3.

[0053] S1220: Writing an identifier of at least one video slice file corresponding to the playback interval into an index file according to a playback order of at least one video slice file corresponding to the playback interval.

[0054] Write the identifier of the video slice file that is in the front of the playback order into the index file first. For example, if the playback interval includes the front video slice file s1_front.ts of the video stage s1 and the back slow-stop video slice file s1_backslow.ts of the video stage s1, first write the identifier of the front video slice file s1_front.ts into the index file, and then write the identifier of the back slow-stop video slice file s1_backslow.ts into the index file.

[0055] In this embodiment, the index file includes an identifier of at least one video slice file corresponding to the playback interval. When playing to the last video stage, the video slice file at the front of the last video stage is switched to the video slice file at the back of the last video stage. Since the switching overhead of the video slice file is small, the freeze of the wallpaper video when it stops is reduced.

[0056] In this embodiment, the wallpaper video includes a first scene video, a second scene video and a transition effect video, the first scene video includes at least one video stage, and the second scene video includes at least one video stage. The waiting playback interval includes the last video stage in at least one video stage of the first scene video, the transition effect video, and the last video stage in at least one video stage of the second scene video. The index file corresponding to the waiting playback interval contains the identifier of the video slice file corresponding to the last video stage in at least one video stage of the first scene video, the identifier of the video slice file corresponding to the transition effect video, and the identifier of the video slice file corresponding to the first video stage in at least one video stage of the second scene video.

[0057] When it is necessary to play videos of two different scenes, a transitional animation video is added between the two scenes. The transitional animation video can transition from one scene video to another scene video, thereby reducing the sense of separation between the different scene videos.

[0058] The first scene video includes at least one video stage. A video slice file corresponding to the last video stage in at least one video stage of the first scene video is generated. For example, if the first scene video includes video stage 1 and video stage 2, then the last video stage in at least one video stage of the first scene video is video stage 2, and a video slice file corresponding to video stage 2 is generated.

[0059] The second scene video includes at least one video stage. A video slice file corresponding to the first video stage in at least one video stage of the second scene video is generated. For example, if the second scene video includes video stage 3 and video stage 4, then the first video stage in at least one video stage of the second scene video is video stage 3, and a video slice file corresponding to video stage 3 is generated.

[0060] Generate a corresponding video slice file according to the transition effect video. The interval to be played includes the last video stage in at least one video stage of the first scene video, the transition effect video, and the first video stage in at least one video stage of the second scene video. The playback order is to first play the last video stage in at least one video stage of the first scene video, then play the transition effect video, and finally play the first video stage in at least one video stage of the second scene video. The index file corresponding to the playback interval includes the identifier of the video slice file corresponding to the first stage, the identifier of the video slice file corresponding to the transition effect video, and the identifier of the video slice file corresponding to the second stage. For example, the interval to be played includes video stage 2 of the first scene video, video stage 4 of the second scene video, and the transition effect video. Then, the index file corresponding to the interval to be played includes the identifier of the video slice file corresponding to video stage 2, the identifier of the video slice file corresponding to the transition effect video, and the identifier of the video slice file corresponding to video stage 4.

[0061] In this embodiment, when two videos of different scenes need to be played, a transitional dynamic effect video is added between the two videos of different scenes, so that a smooth transition between different scenes can be achieved, thereby improving the user experience. At the same time, only the identifier of the video slice file needs to be added to the index file, and there is no need to synthesize the videos of different scenes and the transitional dynamic effect video, thereby avoiding taking up too much storage space.

[0062] In this embodiment, the wallpaper video includes multiple front videos and one back video, and the multiple front videos correspond to screen-off pictures at different positions on the screen. The step S1100 includes: generating a video slice file corresponding to each front video based on the multiple front videos; generating a video slice file corresponding to the back video based on the back video. Before the step S1300, the method also includes: determining a corresponding interval to be played according to the position of the screen-off picture on the screen, and the index file corresponding to the interval to be played includes an identifier of the video slice file of the front video corresponding to the position of the screen-off picture on the screen and an identifier of the video slice file of the back video.

[0063] Always on display means that when the screen of an electronic device is off, the image is still displayed in some areas of the screen. When a part of the screen displays the same color for a long time, it will cause aging of the area. To avoid this problem, the image displayed in the off state is repeatedly moved to different positions on the screen.

[0064] For the screen-off screen displayed in each position, set a corresponding front video. At the same time, for the screen-off screen displayed in all positions, set a common back video, and all front videos can smoothly transition to the back video. While maintaining a smooth transition effect, the size of the front video can be reduced, thereby reducing the total size of the wallpaper video. The same back video will be played after each front video is played. For example, the screen-off screen can be displayed in four different positions on the screen, and the screen-off screen has four states. Set four front videos to correspond to the four states of the screen-off screen. The four front videos share one back video.

[0065] For each front video, a corresponding video slice file is generated. Similarly, for the back video, a corresponding video slice file is also generated. For example, if the wallpaper video includes four front videos and one back video, then four video slice files corresponding to the four front videos are generated, and one video slice file corresponding to the back video is generated.

[0066] A playback interval is preset for each front video, and the playback interval includes the front video and the back video. The identifier of the video slice file corresponding to the front video and the identifier of the video slice file corresponding to the back video are written into the index file corresponding to the playback interval. After the screen is turned on, the corresponding interval to be played is determined according to the position of the screen-off image on the screen.

[0067] For example, the four types of front videos are front video 1, front video 2, front video 3, and front video 4. When the screen-off image is displayed at position 1 on the screen, the interval 1 to be played is determined after the screen is turned on, and the interval 1 to be played includes the front video 1 and the back video. The video slice file corresponding to the front video 1 and the video slice file corresponding to the back video are played in sequence. When the screen-off image is displayed at position 2 on the screen, the interval to be played is determined after the screen is turned on, and the interval to be played includes the front video 2 and the back video. The video slice file corresponding to the front video 2 and the video slice file corresponding to the back video are played in sequence.

[0068] In this embodiment, corresponding front videos are set according to different positions of the screen-off picture on the screen, and a back video is shared. When the screen is on, the playback interval is determined according to the position of the screen-off picture on the screen, and the identifier of the video slice file of the front video corresponding to the position of the screen-off picture on the screen is obtained from the index file, and the back video is reused to reduce the total size of the wallpaper video.

[0069] The wallpaper video playback method provided in the embodiment of the present application can be executed by a wallpaper video playback device. In the embodiment of the present application, the wallpaper video playback device performing the wallpaper video playback method is taken as an example to illustrate the wallpaper video playback device provided in the embodiment of the present application.

[0070] like Figure 3As shown, this embodiment provides a wallpaper video playback device 300, the device comprising:

[0071] A first generating module 301, configured to generate a plurality of video slice files based on a wallpaper video;

[0072] A second generating module 302 is used to generate an index file corresponding to each of the multiple playback intervals of the wallpaper video and the multiple video slice files, each of the index files including an identifier of at least one video slice file, and the at least one video slice file is a file among the multiple video slice files used for playing in the corresponding playback interval;

[0073] The playing module 303 is used to play the at least one video slice file according to the identifier of the at least one video slice file included in the index file corresponding to the interval to be played, and the interval to be played is any one of the multiple playback intervals.

[0074] In this embodiment, multiple video slice files are generated according to the wallpaper video, and a corresponding index file is generated for each playback interval of the wallpaper video. The identifier of the video slice file played in the corresponding playback interval is stored in the index file. When playing, only the video slice files in the playback interval need to be decoded, and the videos outside the playback interval do not need to be decoded, which reduces the power consumption when the wallpaper video is played and the memory occupied by the wallpaper application. In addition, there is no need to jump during playback, which avoids the freeze during the jump and ensures the fast display of the first frame image.

[0075] In one embodiment, the first generating module includes:

[0076] A first acquisition submodule is used to acquire an image frame corresponding to each video stage according to multiple video stages corresponding to the wallpaper video, and a playback interval includes at least one video stage;

[0077] A first generating submodule, configured to generate a front-segment video slice file corresponding to the video stage according to first N image frames in the image frames corresponding to the video stage and a first frame rate, where N is a positive integer;

[0078] A second generating submodule is used to generate a latter video slice file corresponding to the video stage according to the latter M image frames among the image frames corresponding to the video stage and the first frame rate, where M is a positive integer, and the number of image frames corresponding to the video stage is the sum of N and M;

[0079] The third generating submodule is used to generate a rear-segment slow-stop video slice file corresponding to the video stage according to the rear M image frames corresponding to the video stage and a second frame rate, wherein the second frame rate is lower than the first frame rate.
