Animation files are popular because of their rich presentation effects. Because the animation file occupies a larger memory than the picture file, the more system resources are consumed during playing, so that the animation file can not be smoothly played at some terminals with poorer performance, and therefore, how to stably display the animation file on the same display position on terminals with different performances is very critical.

The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
At present, advertisement display positions exist on pages of a plurality of APP, are used for putting advertisements, and can display pictures and also display animations on the display positions so as to achieve the display effect. The animation file is popular because of the abundant display effect, but the animation file occupies more memory and occupies more system resources during playing, so that the animation file has higher requirements on the performance of terminal equipment for playing the animation file. Because the content of the same exhibition stand needs to be displayed on terminals with different performances, compared with the animation file with larger pictures, the animation file occupies more memory resources, and therefore, the animation file cannot be smoothly played on some terminals with poorer performances. In order to enable the animation file to be stably displayed on terminal equipment with different performances so as to ensure the advertisement display effect of each display position, an improvement on the playing method of the animation file is required.
Based on this, the embodiment of the present disclosure provides a playing method of an animation file, which can determine whether a terminal device supports playing of the animation file based on performance parameters of the terminal device playing the animation file to be displayed, if not, select a pre-marked specified frame image from the animation file to convert into a picture file, and then play the picture file, so as to ensure that the terminal device with poor performance can also stably display by degrading the animation file into the picture file.
Specifically, as shown in fig. 1, the animation playing method may include the following steps:
s102, judging whether terminal equipment supports playing of the animation file or not based on performance parameters of the terminal equipment playing the animation file to be displayed;
s104, if not, acquiring a specified frame image from the animation file and converting the specified frame image into a picture file;
s106, displaying the picture file.
The animation file playing method provided by the embodiment of the specification can be used for various terminal devices including mobile phones, tablets, notebook computers, desktop computers and the like. The animation playing can be the animation playing of the APP page or the playing of the browser page.
In some embodiments, the method may be used for playing animation files of various advertisement slots in an APP or browser page. Currently, various APP or browser pages provide advertisement display sites for advertisement display. As shown in fig. 2, still pictures are often used for advertisement presentation at advertisement display sites, but still pictures are less abundant in presentation effect than animation files, so that animation files are more popular in the field of advertisement presentation. However, since the animation file occupies a large memory, the system resources consumed during playing are also large, and thus some terminal devices with poor performance may not be played or may not be played smoothly.
The animation file in the embodiment of the present specification may be a lottie file, where lottie is a library supporting Android, iOS and reactive and implementing animation effects quickly by using json files. After the AE software draws the animation, the user can convert the animation into an animation file in json format through the lottie, which is called a lottie file, when the animation needs to be played, the lottie file can be directly loaded, and the lottie player can analyze and render the lottie file according to an operating system corresponding to the equipment and then can play the lottie file. The lottie file has the characteristics of small file memory, fine control, rich animation showing capability and the like, so that the lottie file is very suitable for advertisement showing.
Because the content displayed in the display position can be either a picture file or an animation file, the terminal equipment does not know whether the file to be displayed is a picture file or an animation file when detecting an instruction for displaying the content in the display position, in some embodiments, after the terminal equipment obtains the file to be displayed from the server, the terminal equipment can judge whether the file to be displayed is a picture file or an animation file, if the file is a picture file, the picture file can be directly loaded to display the picture file by using a picture display control, wherein the picture file is generally a file in a format such as jpg, png, jpeg, gif, and therefore, whether the file is a picture file can be judged according to the format of the file. If the file to be displayed is determined to be the animation file, whether the terminal device supports playing of the animation file can be determined. Whether the file to be displayed is an animation file can be determined according to characteristics of various animation files, for example, the suffix name of the file to be displayed and the fields contained in the file can be determined, and if the suffix name of the file to be displayed is a specified suffix name and the file contains a specified field, the file can be determined to be an animation file. Taking a lottie file as an example, the lottie animation file is a file in json format, and the file contains fields of layers and assems, if the file is loaded into the animation file, the suffix name of the file to be displayed is judged to be json, and the file comprises the two fields of layers and assems, the file can be judged to be the lottie file. Of course, similar methods may be employed for determining other types of animation files.
When the file to be displayed is obtained and the file is determined to be the animation file, whether the terminal equipment supports playing of the animation file can be judged according to the performance parameters of the terminal equipment. For example, the model of the terminal device may be obtained, and whether the terminal device supports animation playback may be determined according to the model. In some embodiments, the performance parameter of the terminal device may be a model of the terminal device, a CPU model of the terminal device, a GPU model of the terminal device, or a memory parameter, and one or more performance parameters on the terminal device may be combined to determine whether the terminal device supports animation playback.
In some embodiments, in order to accurately determine whether the terminal device supports playing of the animation file, the terminal device with different performance parameters may be tested in advance, so as to determine a correspondence between the performance parameters of the terminal device and the file types supporting playing. For example, mobile phones of different models can be used to play the lottie file, and then whether the lottie file is supported by the various models is obtained. Of course, other performance parameters or a combination of multiple performance parameters may be adopted to determine, and finally, a relationship list of the performance parameters and the file types supporting playing may be obtained. In determining whether the terminal device supports playback of the animation file, a determination may be made with reference to the list.
Of course, if it is determined that the terminal device supports the animation playing, the animation player is directly loaded to play. Taking a lottie file as an example, if it is determined that the terminal device supports playing of the lottie file, directly loading a lottie player to play the lottie file. If the terminal equipment does not support the animation playing, acquiring a specified frame image from the video file, converting the specified frame image into a picture file, and displaying the picture file by adopting a picture display control. The appointed frame image is one or more predetermined frames of images, and the images can better show advertising effect, so that when the animation file cannot be played, the images are played. Before the designated frame image is played, the designated frame image can be converted into a picture file which can be displayed, for example, a picture file which can be converted into a jpg, png, jpeg, gif format and the like, and then the picture file is displayed by the picture display control is loaded. In some embodiments, in order to accurately and quickly obtain the specified frame image when the animation file cannot be played, the specified frame image may be marked in advance, the identification information and the file to be played are stored together in the server, and the client may obtain the identification information of the specified frame image at the same time when the file to be played is obtained, and obtain the image according to the identification information. After parsing the lottie file, all the image frames of the lottie file can be parsed into an array in order, each frame is in the array and has a number, for example, the 5 th frame number is 5, so that the identification information of the specified frame image can be the sequence number of the image frame, when the playing file is acquired, the sequence number of the specified frame image is acquired at the same time, and the specified frame image is determined by the sequence number. According to the animation playing method provided by the embodiment of the specification, the animation file is subjected to degradation treatment and converted into the picture file, so that the animation file can be displayed in the form of the picture file on the terminal equipment which does not support the playing of the animation file, the display of the display content is not influenced, and the stable display of the display content on terminals with different performances is ensured.
Of course, since the degradation process is directly performed on the animation file, the display effect is greatly weakened when the specified frame image is obtained from the animation file and converted into the picture file for display. Therefore, in some embodiments, the file content in the animation file may be divided into different categories according to specific functional effects in advance, and corresponding marks are added, when the animation file needs to be played, whether to delete the content of the animation file is determined according to the performance parameters of the terminal device playing the animation file, if so, the file content to be deleted is determined, and then the file content to be deleted in the animation file is deleted and then used for playing. Thus, the same animation file can be adapted to terminal devices with different performances.
When the terminal device detects the animation playing instruction, the terminal device can acquire the animation file to be played from the server. In general, the animation file is a high-quality, complete animation file containing file contents corresponding to all functional effects of an animation, which is prepared in advance, and the animation file can be smoothly played only by a terminal device with high performance. In order to determine which file contents can be deleted according to the performance parameters of the terminal device during playing, the file contents of the animation file can be classified and marked in advance according to the specific functional effects thereof. For example, an animation file may include different layers, each layer has different functional effects, some layers are necessary for displaying an animation, and some layers may only serve to enhance the display effect of the animation. Therefore, for some terminal devices with poor performance, in order to smoothly play the animation file, some display effects can be sacrificed, and some layers which only enhance the play effects are deleted and then played for the terminal device. In order to facilitate determining which file contents in the animation file can be deleted, the file contents of the animation file may be classified in advance according to the functional effects and corresponding marks may be added, for example, an identifier for indicating functions such as "animation show necessity" or "adding animation effects" may be added to each layer to distinguish each layer.
In general, for descriptive files, it may be convenient to sort and tag the file content, so the animation file may be a json-format animation file. For example, a lottie file may be used. The lottie file contains several parts of the file content, where "layers" represent layers of the animation file, and "assets" represent resource information of the animation file, and in some embodiments, if the animation file is a lottie file, the file content to be deleted may be a part of layers inside "layers" or a part of layers inside "assets".
After the animation file to be played is obtained, the terminal device can obtain its own performance parameters. In some embodiments, the performance parameter may be one or more of a model of the terminal device, a CPU model of the terminal device, a GPU model of the terminal device, an operating system of the terminal device, and a memory parameter of the terminal device.
After the performance parameters are obtained, the terminal equipment can determine whether to adapt to the file content of the animation file according to the performance parameters, and if the performance of the terminal equipment is not suitable for the animation file with higher quality, the terminal equipment can not smoothly play the animation file, so that the file content in the animation file can be deleted, the consumed memory of the animation file can be reduced, and the animation file can be smoothly played on the terminal equipment. Because the content contained in the animation file which can be smoothly played by the terminal equipment with different performance parameters is different, before deleting the file content of the animation file, determining which file content to delete is needed according to the performance parameters of the terminal equipment and the marks of the file content in the animation file, and then deleting the determined file content to be deleted and then playing the file content. For example, the terminal device may read the type of its own CPU, determine the number of cores of the CPU according to the type of the CPU, and if the CPU is four cores, it is considered that the performance is better, and it is possible to play the animation file with higher quality, so that it is not necessary to prune the file content of the animation file, if the CPU is two cores, it is considered that the performance is general, and therefore it is possible to delete a small part of the file content only for enhancing the display effect from the animation file, and of course, if the CPU is a single core, it is considered that the performance is worse, and therefore it is necessary to delete a large part of the file content for enhancing the display effect. Of course, the above is a simpler example for facilitating understanding of the list, and in practical operation, various performance parameters of the terminal device can be combined for consideration, and the deleted file content can be classified and marked according to the functional effect of the file content and the acting specific, and the parts of the file content which can be deleted by the terminals with different performances are determined in advance, and corresponding marks are made. So that the file content to be deleted can be quickly determined and deleted according to the performance parameters and the file content marks during playing.
For example, a file of lottie for an animated scene of a firework, the layers in the lottie file containing the following classes: 1. basic firework shapes (e.g., firework shape pictures, colors, trajectory data); 2. light effects (e.g., halation pictures and data displayed in the track for firework shape); 3. particles (e.g. pictures of a large number of spots, color, trajectory data). However, in some cases, various performance parameters of the mobile phone can be comprehensively considered to divide the mobile phone into a high-end machine, a middle-end machine and a low-end machine, for the high-end machine, the animation file containing the 3 layers can be smoothly played, for the middle-end machine, the part of the particles can be deleted, because the part is only used for increasing the effect, the firework which can still be seen is removed, but the display effect is slightly worse than that of the complete animation file, the animation effect is not influenced, and therefore, the middle-end machine can also smoothly play. For the low-end machine, the particle and light effect parts can be deleted, the particle and light effect parts are removed, the firework can be seen from the shape simply, the display effect is sacrificed, the performance of rendering on the mobile phone is reduced, and the firework can be smoothly played in the low-end machine.
In some embodiments, terminal devices with different performance parameters may be adopted in advance to play animation files containing different file contents, a great number of experiments are performed to observe the smoothness of the playing process, and then the corresponding relationship between the performance parameters of the terminal devices and the file contents of the animation files is obtained. After the performance parameters of the animation file and the terminal device are obtained, whether the file content of the animation file needs to be deleted or not can be determined according to the corresponding relation between the performance parameters of the terminal device and the file content of the animation file, and if the file content needs to be deleted, the file content to be deleted is what. The corresponding relation between the performance parameters of the terminal device and the file contents of the animation file can be determined through a large number of tests, for example, the terminal device with different performance parameters can be adopted to play the animation file with the file contents of different functions deleted, the smoothness of the animation file is observed, and if the animation file is smooth, the performance parameters are considered to be matched with the file contents. For example, we can play the animation file with the file content of different functions deleted by using three types of mobile phones of model 1, model 2 and model 3, and perform a great deal of tests, and assume that the initial animation file comprises the file content of four types A, B, C, D, the test finds that the mobile phone of model 1 can smoothly play the complete animation file, recorded as an animation file (A, B, C, D), the mobile phone of model 2 can smoothly play the animation file containing the file content of three types A, B, C, recorded as an animation file (A, B, C), and the mobile phone of model 3 can only smoothly play the animation file containing the two functions A, B, recorded as an animation file (A, B), so that a corresponding relation between the model and the file content of the animation file can be obtained, (model 1-ABCD, model 2-ABC and model 3-AB). The file content of the animation file can be classified and marked in advance according to the functional effect, when an animation file playing instruction is received, the animation file and the model type of the mobile phone can be obtained, and if the model of the mobile phone is model 1, the file content is not required to be deleted and the mobile phone is directly played. If the mobile phone model is model 2, according to the corresponding relation between the performance parameter and the file content, the file content D corresponding to the function D to be deleted can be determined, so that the file content D in the animation file can be deleted and then played. If the mobile phone model is model 3, according to the corresponding relation between the performance parameter and the file content, the file content C and the file content D corresponding to the function C, D to be deleted can be determined, so that the file contents C and D in the animation file can be deleted and then played.
In some cases, in order to quickly delete file contents to be deleted from file contents of an animal file, the file contents to be deleted may be marked with an identification corresponding to a performance parameter when marking the file contents. For example, the file content A, B, C, D of the animation file may be marked with an identifier corresponding to the model number, for example, the number 2 is used to identify the model 2, and the content that needs to be deleted by the model 2 is marked with D2 after D, which is marked with D2, so that it is known that if the model of the terminal device is determined to be 2, the file content D may be deleted. Of course, the above marking mode is only a simple example listed in the specification, and the specific marking mode can be flexibly set according to actual requirements, and only the content of the file to be deleted corresponding to the mobile phone with certain performance can be determined according to the marking, which is not limited in the specification.
By the method, the same animation file can be ensured to be smoothly played on terminal equipment with different performances, only one animation file is required to be manufactured when the animation file is manufactured, multiple animation files are not required to be manufactured, only one animation file is required to be loaded when the animation file is loaded, multiple animation files are not required to be loaded, and therefore operation is convenient, and system resources are saved. Only when the performance of the terminal equipment is poor and the deleted animation file cannot be smoothly played, a degradation scheme is adopted, otherwise, a scheme of deleting the layer can be adopted, so that the display effect can be ensured to the greatest extent and stable display of the file can be ensured.
In addition, in the prior art, when playing the animation file, the specific playing details are not controlled according to the preset sequence, for example, the previous frames are incoming, the middle frames circulate in a certain mode, and finally the animation is withdrawn from the previous frames, namely, the animation file cannot be controlled to play according to a certain instruction to realize a specific animation effect, and in addition, only one animation effect is generally displayed in the current animation file, so that the animation effect which can be displayed by the current animation is very limited. For some scenes, such as animation of advertisement showplace presentation in a page, higher requirements are placed on animation effects.
Thus, in some embodiments, control instructions for playing an animation may be designed in advance for the animation file and the desired animation effect, where the control instructions are used to control the animation effect when the animation file is played, for example, the motion and path of each specific frame of image in the animation file and the playing order of the image frames may be controlled, so that the animation file is played according to the control instructions to achieve a specific effect. For example, a certain animation file includes 40 frames of images, in order to enable the animation file to present a specific effect during playing, a control instruction can be designed, for example, the 1 st frame to the 10 th frame of images are controlled to be the approach images, then the middle active images (for example, the 11 th frame to the 30 th frame) are circularly played for 3 times, the approach images (for example, the 30 th to the 40 th frames of images) are played after being paused for 2 seconds, and the playing details of the whole animation file can be controlled by controlling the specific action of each frame of images in the animation file and the playing sequence of each frame of images, so as to achieve a richer animation effect. In some embodiments, the control instructions include instructions to control some actions for specific certain image frames in the animation file, such as an approach instruction, a transition instruction, a loop instruction, a departure instruction, and the like.
In some embodiments, the animation file to be played and the control instruction of the animation file to be played may be directly stored in a server where the server is located, and after receiving a request from the client to obtain the animation file to be played, the server returns a response result, where the response result may be directly the control instruction of the animation file to be played and the animation file to be played, so that the client may directly obtain the control instruction of the animation file to be played and the control instruction of the animation file to be played, and play the animation file according to the control instruction.
Of course, if all the animation files are stored in the same server, the client obtains the animation files from the same server, which results in a higher processing pressure of the server, a longer response time for responding to the request of the client, and possibly causing network congestion when the network is poor. To avoid this, in some embodiments, only the attribute information of the animation file may be stored at the server, where the attribute information includes the storage address and the control instruction of the animation file, and the animation file is stored in a distributed manner in other servers. Thus, after receiving the request of the client to acquire the animation file to be played, the server returns a response result, wherein the response result can be attribute information of the animation file. After obtaining the attribute information, the client can analyze the attribute information to obtain the storage address and the control instruction of the animation file, and then obtain the animation file according to the storage address. In some embodiments, the attribute information may be json format data, for example, the attribute information may be json objects, and different fields are included therein for storing the storage address of the animation file and the control instruction, respectively. After the client acquires the json object, analyzing each field to obtain the storage address and the control instruction of the animation file.
In some embodiments, the storage address of the animation file may be stored in the CDN server. The CDN is a content delivery network constructed on the network, and by means of CDN servers deployed in various places, a user can obtain required content nearby through load balancing, content delivery, scheduling and other functional modules of the central server, network congestion is reduced, and user access response speed and hit rate are improved. The server side can serve as a central server to deploy the animation file to each CDN server, and then store the storage address of the animation file in the newly added extension field in the attribute information, namely the json object. Of course, the animation file may be manually stored in the CDN server, and then the storage address may be manually added to the attribute information, which is not limited in this application. In this way, the server side as a central server deploys the animation file to each CDN server, and adds an extension field to the attribute information to store the storage address. After the client acquires the attribute information from the server, the client analyzes the attribute information to obtain a storage address and a control instruction of the animation file, and then acquires the animation file from the CDN server nearby according to the storage address, so that the processing pressure of the server can be reduced, and the response speed to the client request can be improved.
Since the control instruction for playing the animation according to the embodiment of the present disclosure is designed according to the desired animation effect, in order to identify and execute the control instruction during playing the animation, the player may be improved in the implementation of the present disclosure, so that the player may play the animation file according to the control instruction designed by itself. Taking a lottie file as an example, currently, an open source player of the lottie file does not support a self-designed control instruction, so that the lottie player needs to be self-defined and packaged, then the custom lottie player is adopted to play the animation file so as to identify the control instruction, and the play of the animation file is controlled according to the control instruction, so that the expected animation effect is achieved.
By the method, the animation playing control instruction can be designed according to the expected animation effect, so that the playing of the animation can be controlled according to the control instruction, various animation effects can be achieved, the display effect of the animation file can be enriched and enhanced, and different control instructions can be designed aiming at the same animation file, so that the animation file can display various animation effects.
In order to further explain the animation file playing method provided in the embodiments of the present specification, a specific embodiment will be explained below.
At present, various APP pages can provide advertisement display positions for advertisement display. The display position can display pictures and also can display animation files. The lottie file in the animation file is convenient to use because of small file, so that the lottie file is very suitable for advertisement display. Because the animation file occupies a larger memory than the picture file, it may not be displayed in some mobile phones with poorer performance. In order to enable the content of the booth to be stably displayed on mobile phones with different performances, the embodiment of the present disclosure provides a method for displaying the content of the booth, and the content of the booth in the embodiment is assumed to be a picture or a lottie file, and a specific process is shown in fig. 3.
When the mobile phone client detects that the display position needs to play the display content, a request for acquiring the display position content is sent to the server, the server returns a file to be displayed (S301), the mobile phone client detects whether the file is a lottie file (S302), if not, the file is a picture file, and if so, a picture display control is directly loaded to display the picture file (S303). If the mobile phone is a lottie file, judging whether the mobile phone model supports the playing of the lottie file (S304), and playing the lottie file by adopting mobile phones of different models in advance to obtain a list of mobile phone models which do not support the playing of the lottie file, and judging whether the mobile phone supports the playing of the lottie file according to the list. If so, the lottie player is directly loaded to play the lottie file (S305), and if not, a pre-marked 'degraded frame' is acquired from the lottie file (S306), wherein the 'degraded frame' is a predetermined frame image and is used for playing the 'degraded frame' when the mobile phone does not support the playing of the lottie file. The "degraded frame" is converted into a picture file (S307), and then the picture is presented using a picture presentation control (S308). The specific process is shown in fig. 4, in which, whether the file to be displayed is a lottie file may be determined according to the characteristics of the lottie file, and the specific process is that the file to be displayed is firstly obtained from the server (S401), then whether the suffix name of the file to be displayed is json is determined, if not, the file is described as a non-lottie file (S403), if yes, whether the file content includes a layers field and an errors field (S404), if yes, the file is described as a lottie file (S405), and if not, the file is described as a non-lottie file (S403).
By the method, when the mobile phone supports the playing of the animation file, the display of the mobile phone client directly plays the animation file, and when the mobile phone does not support the playing of the animation file, the animation file is degraded, and a pre-designated frame of image is converted into a picture and then played.
