Description

Technical Field

[0001] This invention relates to the field of animation resource processing technology, and in particular to a method, apparatus, device, and medium for generating and playing universal animation format files. Background Technology

[0002] With the development of animation technology, various animated GIF and animation resource formats are currently available on the market, such as GIF, APNG, WebP, and SVG, as well as SVG, MP4, and VAP. Different resource formats vary in color support, compression methods, compatibility, and file size at the same quality. Therefore, in practical applications, different resource formats must be selected according to different scenarios.

[0003] However, the way animation resources are used in existing technologies has significant drawbacks:

[0004] 1. The client needs to maintain multiple sets of player code: Since different animation formats are used in different scenarios, the client needs to develop and maintain corresponding player logic for each format, resulting in code redundancy and high maintenance costs;

[0005] 2. Poor format update compatibility: When business requirements change and the animation format needs to be changed, the existing client code cannot be compatible with the new format. The code must be modified and a new version must be released, which not only increases development costs but may also affect user experience.

[0006] 3. Lack of a unified resource management mechanism: The caching and update logic for resources of different formats is not unified, and the client needs to design a separate caching strategy for each format, which further increases the development complexity;

[0007] 4. Compatibility issues with older player versions: When adding new animation formats, older client players may not support the format, resulting in blank screens where the animation cannot be played, affecting the user experience. Summary of the Invention

[0008] This invention provides a method, apparatus, device, and medium for generating and playing universal animation format files, which solves the defects in the prior art where the variety of animation formats leads to the need for the client to maintain multiple sets of player code and the need to modify and redistribute the code when the format is updated.

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0058] It should be noted that in the description of the embodiments of the present invention, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and do not limit the number of objects; for example, a first object can be one or more. Furthermore, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0059] The following is combined with Figures 1 to 5 This invention describes a method, apparatus, device, and medium for generating and playing a universal animation format file.

[0060] like Figure 1 As shown, this invention provides a method for generating a universal animation format file. The generated universal animation format file is a packaged file capable of carrying any commonly used animation resources and commonly used animated GIF resources. The method specifically includes the following steps:

[0061] Step 110: Import the original animation resources in any common animation format or common animated GIF format. The common animation format includes at least one of svga, mp4, and vap, and the common animated GIF format includes at least one of gif, apng, webp, and svg.

[0062] Step 120: Compress and optimize the original animation resources to obtain compressed animation resources.

[0063] Specifically, the original animation resources are packaged and compressed using optimization algorithms to reduce file size, balancing animation quality and transmission efficiency. The compression optimization algorithm can be either lossless or lossy compression, depending on the requirements.

[0064] Step 130: Create a file header configuration for a generic animation format file. The file header configuration records basic file information, including: the size of the generic animation format file, the format of the original animation resource, and the player version number of the original animation resource.

[0065] Specifically, the file header configuration, as the core metadata area of ​​a common animation format file, records basic file information, including but not limited to:

[0066] (1) Size of the general animation format file: The total number of bytes of the general animation format file, which can be used for client download and parsing verification;

[0067] (2) Original animation resource format: Records the specific format of the original animation resources packaged inside, such as svga, webp, mp4, etc., to provide the player with the basis for adaptation;

[0068] (3) Player version number of the original animation resource: used to identify the compatible version of the player corresponding to the general animation format file, and supports backward compatibility judgment.

[0069] Step 140: Embed a preset single-frame static image as a default placeholder image into the general animation format file, wherein the default placeholder image is used for placeholder display when the original animation resource cannot be played.

[0070] Specifically, considering compatibility issues with older player versions and resource download time, the universal animation format file also includes a default image of a single frame of animation. The preset single-frame static image is used as a placeholder when the player does not support the version of the original animation resource that can be played, or when the original animation resource is corrupted and cannot be played, to avoid blank scenes.

[0071] In some embodiments, the preset single-frame static image is a screenshot of the first frame of the original animation resource or a static image uploaded by the user.

[0072] Step 150: Encapsulate the compressed animation resources, the file header configuration, and the default placeholder image to generate the universal animation format file.

[0073] Specifically, a dedicated universal animation format resource generation tool is used to convert the original animation resource format to a universal animation format. The tool integrates resource processing and preview functions to ensure the usability of the output universal animation format file. Animators can preview and verify the playback effect of the universal animation format file before exporting to ensure that the animation is displayed normally.

[0074] In some embodiments, the generated general animation format file has the file extension "gag", which stands for General Animation Graphics.

[0075] To ensure that clients can clearly know whether resource files have been cached or need to be updated, in some embodiments, the file names of general animation format files adopt the naming format of "name word + time suffix (milliseconds) + .gag" to ensure that each generated file name is unique. The timestamp can be automatically added by the system when the file is generated. By adding time suffix differences, the client can quickly identify the resource cache status and update needs.

[0076] like Figure 2 As shown, the present invention also provides an animation playback method, which can be applied to a player for the aforementioned common animation format files. The player has built-in playback logic for common animation format files, and specifically includes the following steps:

[0077] Step 210: Obtain the universal animation format file.

[0078] Specifically, taking the application client as an example, the client can have the aforementioned player built-in, and the client can download and obtain the target general animation format file from the server according to the business scenario requirements.

[0079] To enable the client to quickly determine the resource status by filename and clearly know whether the resource file has been cached, in some embodiments, the following is included before step 210:

[0080] Based on the filename of the universal animation format file, determine whether the universal animation format file exists in the local cache;

[0081] If so, the corresponding general animation format file in the local cache is directly called, and the original animation resource is played using the corresponding playback logic;

[0082] If not, proceed to step 210 and store the general animation format file in the local cache.

[0083] In this embodiment, the client maintains a local cache library of common animation format files. Before downloading, the filename is compared with the filename in the cache library. If a filename with the same name exists in the cache, the locally cached file can be directly accessed; otherwise, the common animation format file is downloaded and cached locally.

[0084] To further inform the client whether resource files need to be updated, in some embodiments, the filename of the generic animation format file includes a name and a timestamp, which is automatically added by the system when the file is generated.

[0085] Accordingly, determining whether the common animation format file exists in the local cache based on the filename of the common animation format file includes:

[0086] Based on the naming words and timestamps of the filenames of the general animation format files, determine whether the general animation format files exist in the local cache;

[0087] If the local cache contains a file with the same name but different timestamps as the general animation format file, the old file in the local cache will be deleted, and the general animation format file will be cached in the local cache.

[0088] In this embodiment, a naming rule that includes a timestamp in the file name is adopted. The local cache is compared to see if there is a file with the same file name. If the names are the same but the timestamps of the name suffixes are different, it means that the new file is an updated version of the old file in the cache. In this case, the old file is deleted and the downloaded new file is updated and stored in the local cache.

[0089] Step 220: Parse the general animation format file and extract the format of the original animation resource.

[0090] Specifically, the player decodes and parses the acquired common animation format files to extract core data. The player reads the file header configuration of the common animation format files and parses out information such as file size, original animation resource format, and version number.

[0091] To facilitate the retrieval of animation resource data, in some embodiments, the original animation resource data packaged in a common animation format file is also cached in the local cache.

[0092] Step 230: Based on the format of the original animation resource, call the corresponding playback logic to play the original animation resource.

[0093] Specifically, the player flexibly adapts to the playback based on the format of the parsed original animation resource. The player has built-in playback logic for all common animation and GIF formats. The player automatically calls the corresponding playback logic to play the video based on the actual format of the original animation resource parsed from the file header, without requiring any additional configuration on the client side.

[0094] Considering compatibility issues with older player versions and resource download time, in some embodiments, the player parsing also extracts the player version number of the original animation resource. After step 220, the process further includes:

[0095] Determine whether the version number of the player for the general animation format file is lower than the version number of the player for the original animation resource;

[0096] If so, then display the default placeholder image in the general animation format file;

[0097] If not, proceed to step 230.

[0098] In this embodiment, if the version number of the player is lower than the version number of the original animation resource being parsed, that is, the player does not support the current original resource format, the default placeholder image in the general animation format file is directly displayed to ensure the basic user experience.

[0099] In some embodiments, the player can also verify the integrity of the common animation format based on the parsed file size. If the file is corrupted and cannot be played, a default placeholder image is displayed to avoid a blank scene; if the file is intact, step 230 is executed. Furthermore, the original animation resource data packaged in the file is extracted and cached in the client's memory for subsequent playback.

[0100] Understandably, comparing file size and version number simultaneously can determine whether a common animation format file can be played normally.

[0101] The following example illustrates an application scenario where animators use a universal animation format resource generation tool to generate universal animation format files and then play them.

[0102] Taking the common animation format gag as an example, firstly, the animator generates the animation. Let's assume the original animation resource is SVGA. Then, a gag resource generation tool imports this SVGA file. The tool packages the original animation resource, modifies the gag file header configuration, and finally exports a compressed and optimized gag file. Considering compatibility issues with older player versions and resource download time, the gag format also includes a default frame of animation, used as a placeholder when the animation resource cannot be played. To ensure the client clearly knows whether the resource file is cached or needs updating, the generated gag file is named in the format of time extension (milliseconds) + .gag.

[0103] After the client downloads the resource, it uses the gag player to decode and analyze the file; finally, it decodes the file and caches the obtained SVGA data in memory, and then uses the SVGA-specific logic contained in the gag to play it.

[0104] If animators need to update an animation (including changing the original resource format, modifying the animation content, etc.), no client-side code modification is required. For example, if the original animation resource is changed from SVGA to WebP format, and a tool is used to convert it into a GAG file, the new file's filename and extension will differ from the old file due to the different generation times. Since the filename has changed, the client detects this change, automatically recognizes the updated resource, and knows the old cache is no longer needed. It first deletes the old cache, then synchronously downloads the new file and re-decodes it. The re-decoded file contains WebP-related configurations and data. Similarly, playback can be achieved using the WebP-specific logic contained within the GAG ​​file, achieving seamless animation update compatibility. The animation update process requires no code modification on the client side.

[0105] The method for generating and playing a universal animation format file provided above has the following significant advantages compared with existing technologies:

[0106] 1. Single unified format compatible with multiple types of resources: The universal animation format can encapsulate various common animation / GIF formats such as gif, apng, webp, svg, svga, mp4, and vap. Clients with built-in universal animation format players do not need to pay attention to the original resource format, but only need to handle the universal animation format, which greatly simplifies the development process.

[0107] 2. The client only needs to maintain one set of playback code: The player for general animation formats has built-in multi-format preset playback logic, eliminating the need to develop a separate player for each animation format, reducing code redundancy and maintenance costs;

[0108] 3. No need to modify client code for animation updates: Resource updates are identified through time suffix naming rules. The client automatically downloads the new universal animation format file and adapts it for playback. No code modification and redeployment are required, improving iteration efficiency and reducing communication costs.

[0109] 4. Supports backward compatibility: By using the version number and the default placeholder image mechanism, older versions of the player can still display placeholder images even if they do not support the new formats, ensuring a basic user experience and avoiding blank scenes;

[0110] 5. Optimize resource transmission and caching: Common animation format files are compressed and optimized to reduce size and download time; cache status is quickly identified by filename, cache management logic is optimized, and resource loading efficiency is improved.

[0114] Compression module 320 is used to compress and optimize the original animation resources to obtain compressed animation resources;

[0115] A creation module 330 is used to create a file header configuration for a universal animation format file. The file header configuration records basic file information, including: the size of the universal animation format file, the format of the original animation resource, and the player version number of the original animation resource.

[0116] The embedding module 340 is used to embed a preset single-frame static image as a default placeholder image into the general animation format file, wherein the default placeholder image is used for placeholder display when the original animation resource cannot be played;

[0117] The generation module 350 is used to encapsulate the compressed animation resources, the file header configuration, and the default placeholder image to generate the general animation format file.
