DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

FIG. 1 is an application environment diagram of a dynamic image playback method in an embodiment. Referring to FIG. 1 , the application scenario includes a mobile terminal 102 and a server 104, and the mobile terminal 102 is connected to the server 104 through a network. The server 104 obtains the dynamic image identifier to be played; searches for the decoded image set corresponding to the dynamic image identifier to be played, and reads the forward sequence information and reverse sequence information of the decoded image set; displays each forward decoded image in the decoded image set frame by frame based on the forward sequence information; when the last forward decoded image is displayed, displays each reverse decoded image in the decoded image set frame by frame based on the reverse sequence information. Among them, the mobile terminal 102 can be a mobile phone, a tablet computer, etc., the number of mobile terminals 102 can be multiple, and the server 104 can be implemented by an independent server or a server cluster composed of multiple servers. In the embodiment of the present application, the dynamic image playback method can be executed by the server 104, or by the mobile terminal 102, or by the server 104 and the mobile terminal 102. Specifically, the mobile terminal 102 can execute the dynamic image playback method in the embodiment of the present application by a processor.

As shown in FIG2 , in one embodiment, a method for playing a dynamic image is provided. This embodiment mainly uses the method applied to the server 104 in FIG1 as an example. Referring to FIG2 , the method specifically includes the following steps:

S202, obtaining the identifier of the dynamic image to be played.

Among them, dynamic images may include GIF (Graphics Interchange Format) dynamic images, WebP dynamic images, etc. The identification of the dynamic image to be played refers to the identification used to distinguish dynamic images in different states in the short video application when the user plays the dynamic image through the short video application. For example, the user clicks on an installed short video application on the mobile terminal to enter the main interface of the short video application. The main interface is a recommended dynamic image that is being played. When the user wants to play the next dynamic image through a sliding gesture, the next dynamic image is the image corresponding to the identification of the dynamic image to be played. For another example, the user clicks on an installed short video application on the mobile terminal to enter the main interface of the short video application. The main interface includes multiple recommended dynamic images. When the user selects a dynamic image that he wants to play from multiple recommended dynamic images through a clicking operation, the selected dynamic image is the image corresponding to the identification of the dynamic image to be played.

S204, searching for a decoded image set corresponding to the to-be-played dynamic image identifier, and reading the forward sequence information and reverse sequence information of the decoded image set.

Decoding refers to the process of the receiver restoring the received symbols or codes into information, which corresponds to the encoding process. Since the image in the animated image is a compressed bitmap graphic format, before the image is rendered and displayed, the original pixel data of the image must be obtained to perform subsequent drawing operations, that is, the animated image needs to be decoded to obtain a decoded image. The decoded image set includes multiple decoded images after decoding each image frame in the animated image.

The positive sequence information refers to sorting the images in the decoded image set in the positive order, and the reverse sequence information refers to sorting the images in the decoded image set in the reverse order. For example, the decoded image set includes image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5, the positive sequence information refers to the decoded images in the order of image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5, and the reverse sequence information refers to the decoded images in the order of image frame 5, image frame 4, image frame 3, image frame 2 and image frame 1.

S206 , displaying each frame of the decoded image in the decoded image set frame by frame based on the positive sequence information.

Taking the decoded image set including image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5 as an example, the positive sequence information refers to the decoded images in the order of image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5. Displaying each positive sequence decoded image in the decoded image set frame by frame based on the positive sequence information means displaying the images frame by frame in the order of image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5.

S208, when the display of the last frame of the forward-order decoded image is finished, display each frame of the reverse-order decoded image in the decoded image set frame by frame based on the reverse-order sequence information.

Taking the decoded image set including image frame 1, image frame 2, image frame 3, image frame 4 and image frame 5 as an example, the reverse sequence information refers to the decoded images in the order of image frame 5, image frame 4, image frame 3, image frame 2 and image frame 1. After displaying each frame of the decoded image in the decoded image set frame by frame based on the forward sequence information, each frame of the decoded image in the decoded image set is displayed frame by frame based on the reverse sequence information, that is, the images are displayed frame by frame in the order of image frame 1, image frame 2, image frame 3, image frame 4, image frame 5, image frame 4, image frame 3, image frame 2 and image frame 1, so as to ensure the continuity of image display and avoid the situation of image frame jump.

The above-mentioned dynamic image playback method obtains the dynamic image identifier to be played, searches for the decoded image set corresponding to the dynamic image identifier to be played, and reads the forward sequence information and reverse sequence information of the decoded image set to directly obtain the decoded image corresponding to the dynamic image. There is no need to perform decoding processing before displaying each frame of the image, which saves time for subsequent dynamic image loading. Each frame of the forward decoded image in the decoded image set is displayed frame by frame based on the forward sequence information. When the last frame of the forward decoded image is displayed, each frame of the reverse decoded image in the decoded image set is displayed frame by frame based on the reverse sequence information. The forward sequence and reverse sequence are combined to achieve the dynamic image effect, remove the repeated image frames in the dynamic image, and reduce the number of image frames in the dynamic image, thereby effectively improving the dynamic image loading speed.

In one embodiment, searching for a decoded image set corresponding to the to-be-played dynamic image identifier includes: searching for images in pre-cached data based on the to-be-played dynamic image identifier; when a decoded image set corresponding to the to-be-played dynamic image identifier exists in the pre-cached data, obtaining the decoded image set. Cache refers to a memory that can perform high-speed data exchange, and is a buffer for data exchange. In the data processing process of the mobile terminal, for example, when the CPU (Central Processing Unit) needs to read data, it first queries the data from the cache. Reading data from the cache is faster than reading data from the memory. Therefore, cache data helps to improve the subsequent data processing speed. Cache data refers to data stored in the cache, and specifically, data can be stored according to the corresponding relationship between the dynamic image identifier and the decoded image set. For example, the dynamic image corresponding to the to-be-played dynamic image identifier is A. In the cache data, dynamic image A is searched according to the corresponding relationship between the dynamic image identifier and the decoded image set. When there is a decoded image set corresponding to dynamic image A in the cache data, it is not necessary to decode each frame of dynamic image A, and the decoded image set is directly obtained, which can save time for subsequent dynamic image loading.

In one embodiment, the dynamic image playing method further includes: when there is no decoded image set corresponding to the dynamic image identifier to be played in the pre-cached data, obtaining the dynamic image corresponding to the dynamic image identifier to be played; decoding the image frame in the dynamic image to obtain the decoded image set corresponding to the dynamic image identifier to be played. Cache data refers to data stored in the cache, and the data can be stored according to the correspondence between the dynamic image identifier and the decoded image set. For example, the dynamic image corresponding to the dynamic image identifier to be played is B, and the dynamic image B is searched in the cache data according to the correspondence between the dynamic image identifier and the decoded image set. When there is no decoded image set corresponding to the dynamic image B in the cache data, it is necessary to obtain the dynamic image B, and decode the image frames in the obtained dynamic image B to obtain the decoded image set corresponding to the dynamic image B. For example, when a user initiates a request to play a certain dynamic image through a short video application of a mobile terminal, and there is no decoded image of the dynamic image in the cache of the mobile terminal, at this time, the mobile terminal can initiate an image download request to the cloud server, and the image download request carries the dynamic image identifier to be downloaded, and requests the server to return the dynamic image data to the mobile terminal. Specifically, the animated image can be obtained by extracting image frames from a preset video file based on a preset rule, or by combining multiple frames of static images.

In one embodiment, decoding the image frames in the dynamic image to obtain the decoded image set corresponding to the dynamic image identifier to be played includes: decoding the current frame image in the dynamic image to obtain the decoded image of the current frame and display the decoded image of the current frame; decoding the next frame image in the dynamic image to obtain the decoded image of the next frame and display the decoded image of the next frame; obtaining the decoded image set corresponding to the dynamic image identifier to be played according to the decoded image of the current frame and the decoded image of the next frame; after obtaining the decoded image set corresponding to the dynamic image identifier to be played, it also includes: adding the decoded image set corresponding to the dynamic image identifier to be played to the pre-cached data. The acquired dynamic image is decoded according to the image frame, decoding one frame and displaying one frame, so as to achieve the effect of decoding and displaying at the same time, without waiting for all the image frames to be decoded before displaying, which can shorten the waiting time. After all the image frames of the dynamic image are decoded, all the decoded images are added to the cache data, so that when the decoded image set of the dynamic image needs to be read, it can be directly read from the cache without decoding the dynamic image again, which can effectively shorten the time required for loading the dynamic image.

In one embodiment, when the dynamic image corresponding to the dynamic image identifier to be played includes 2m frames of images, the decoded image set includes m frames of images; when the dynamic image corresponding to the dynamic image identifier to be played includes 2m+1 frames of images, the decoded image set includes m+1 frames of images; wherein m is a positive integer. In a short video application, before entering a certain video, a cover animated image is generally displayed first, as shown in FIG3. Taking the video cover animated image including N frames of images as an example, the content of the first frame of the video cover animated image is the same as the content of the Nth frame of the image, the content of the second frame of the image is the same as the content of the N-1th frame of the image, the content of the third frame of the image is the same as the content of the N-2th frame of the image, and so on, as shown in FIG4.

For example, the video cover animation includes 9 frames of images, the content of the 1st frame of image is the same as the content of the 9th frame of image, the content of the 2nd frame of image is the same as the content of the 8th frame of image, the content of the 3rd frame of image is the same as the content of the 7th frame of image, and the content of the 4th frame of image is the same as the content of the 6th frame of image. When the cover animation is played by the traditional dynamic image playing method, as shown in FIG5, the 9 frames of image corresponding to the cover animation are first downloaded, and then the 1st frame of image is decoded and displayed; the 2nd frame of image is decoded and displayed; the 3rd frame of image is decoded and displayed; the 4th frame of image is decoded and displayed; the 5th frame of image is decoded and displayed; the 6th frame of image is decoded and displayed; the 7th frame of image is decoded and displayed... the 9th frame of image is decoded and displayed, and the 1st frame of image is decoded and displayed... and the playback is repeated in this way.

However, the dynamic image playback method in the present application is adopted, as shown in FIG6, after downloading the 9 frames of images corresponding to the cover dynamic image, the first frame of the image is decoded and displayed; the second frame of the image is decoded and displayed; the third frame of the image is decoded and displayed; the fourth frame of the image is decoded and displayed; the fifth frame of the image is decoded and displayed. The decoded image frames are added to the cache, and the repeated image frames are no longer decoded, and the corresponding image frames are directly called from the cache for display later. That is, the dynamic image playback processing flow in the present application is: decode the first frame image, display the first frame image; decode the second frame image, display the second frame image; decode the third frame image, display the third frame image; decode the fourth frame image, display the fourth frame image; decode the fifth frame image, display the fifth frame image; display the fourth frame image - display the third frame image - display the second frame image - display the first frame image - display the second frame image - display the third frame image - display the fourth frame image - display the fifth frame image - display the fourth frame image - display the third frame image... and play in this way in a loop.

The dynamic image playback method in this application can significantly reduce the number of bytes of dynamic images. For example, the number of bytes of a 5-frame dynamic image is about 57% of the number of bytes of a 9-frame dynamic image. In addition, the time required to load a 5-frame dynamic image is about 30% less than the time required to load a 9-frame dynamic image. Moreover, the CPU usage of dynamic images is greatly reduced. Compared with 9-frame dynamic images, the CPU usage of 5-frame dynamic images is reduced from about 40% to 5%.

In one embodiment, the dynamic image playback method further includes: real-time monitoring of the operation request of the dynamic image interface; when the operation request to leave the dynamic image interface is monitored, the decoded image set data is deleted. The dynamic image interface refers to the functional interface of the dynamic image after entering the short video application. The operation request of the dynamic image interface refers to the operation initiated by the user based on the dynamic image interface of the short video application, such as the operation of watching the next dynamic image, the operation of leaving the dynamic image interface, etc. Specifically, the correspondence between the operation and the instruction can be established in advance, for example, the operation of sliding to the right once corresponds to the instruction to jump to the next dynamic image, and the operation of sliding to the right twice in succession corresponds to the instruction to leave the dynamic image interface, etc. When the operation request to leave the dynamic image interface is monitored, the decoded image set data is deleted to release the storage space. For example, the decoded image set data is stored in the cache, and the cache capacity is limited. Therefore, when leaving the dynamic image interface, the decoded image set data corresponding to the dynamic image is deleted, which can timely release the cache space and facilitate the subsequent storage and reading of the cache data.

In one embodiment, obtaining the identification of the dynamic image to be played includes: real-time monitoring of the operation request of the dynamic image interface; when the operation request to enter the dynamic image interface is monitored, obtaining the identification of the dynamic image to be played corresponding to the dynamic image interface. Obtain the correspondence between the pre-established operation and the instruction, for example, the operation of double-clicking the short video application icon corresponds to the instruction to enter the dynamic image interface. When the operation request to enter the dynamic image interface is monitored, obtain the identification of the dynamic image to be played corresponding to the dynamic image interface, find the decoded image set corresponding to the dynamic image identification to be played, and read the forward sequence information and reverse sequence information of the decoded image set; based on the forward sequence information, display each frame of the forward decoded image in the decoded image set frame by frame; when the display of the last frame of the forward decoded image is finished, display each frame of the reverse decoded image in the decoded image set frame by frame based on the reverse sequence information.

It should be understood that, although the various steps in the flowchart of Fig. 2 are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in Fig. 2 may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
