It is known to those skilled in the art that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0055] The word “exemplary” is used hereinafter to mean “serving as an example, example, or illustration.” Any embodiment described as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0056] With the development of Internet technology, in order to make code reuse easier, component-based development will process reusable functions into components. In order to allow developers to find and use different components quickly and easily, in related technologies, component functions can be displayed through GIF images. However, the existing video to GIF technology is inefficient and has poor security, and there is no complete solution or npm plug-in that can meet the needs of video to GIF images.

[0057] Therefore, how to better generate GIF images so that they can display component functions more safely and efficiently has become a technical problem that needs to be solved.

[0058] To solve this problem, the embodiment of the present application provides a GIF generation method, device, equipment and storage medium. The GIF generation method analyzes the track information of the video file to be processed based on the video analysis library, determines the total duration of the video, and converts the video file to be processed into multiple continuous video frame images; based on the total duration of the video and the preset duration, multiple continuous video frame images are divided to obtain video frame image groups corresponding to each preset duration; for each video frame image group, based on the preset interval, multiple target video frame images are extracted from the video frame image group; based on the preset text drawing tool, after drawing a watermark at the preset watermark position of each target video frame image, each target video frame image after drawing the watermark in each video frame image group is synthesized to generate a GIF file. Thereby improving the efficiency and security of the video to GIF technology, and then more safely and efficiently displaying the component functions through GIF images.

[0059] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0060] Figure 1 The application scenario of a GIF generation method provided by an embodiment of the present application is shown. Figure 1 As shown, the server 100 is connected to the terminal device through the network 101 for communication, wherein the network 101 may be but not limited to a local area network, a metropolitan area network or a wide area network, etc., and the number of terminal devices connected to the server 100 may be multiple, for example, the terminal device may include a terminal device 110 of a developer in componentized development, and may also include a terminal device 111 of a user of a target website, etc. The terminal device may be a portable device (e.g., a mobile phone, a tablet computer, etc.), or a computer, a smart screen or a personal computer (PC, Personal Computer), etc.

[0061] The server 100 may be an application-level server storing multiple applications. The server 100 may be any device having networking function and providing data processing capability. For example, the server 100 may be a cloud server or a server set consisting of one or more servers.

[0062] Figure 1 The application scenario is only an example of an application scenario for implementing the embodiment of the present application. The embodiment of the present application is not limited to the above Figure 1 The application scenario described.

[0063] Based on the above Figure 1 Based on the application scenarios shown and the introduction to the above-mentioned related technologies, an embodiment of the present application provides a GIF generation method. Figure 2 A schematic diagram of a GIF generation method provided in an embodiment of the present application is shown, and the specific steps are as follows:

[0064] S201, parsing the track information of the video file to be processed based on the video parsing library, determining the total duration of the video, and converting the video file to be processed into a plurality of continuous video frame images;

[0065] As an example, after obtaining the video file to be processed, the track information of the video file to be processed is parsed based on the video parsing library to determine the total duration and the total number of frames of the video file to be processed, and then the number of frames per second of the video file to be processed is determined based on the total duration and the total number of frames of the video file to be processed, wherein the unit of the determined total duration of the video file to be processed is seconds.

[0066] Specifically, the number of frames per second of the video file to be processed = the total number of frames of the video file to be processed / the total duration of the video file to be processed. For example, if the video file A to be processed is parsed by the video parsing library, the total duration of the video file A to be processed is determined to be 15 seconds, and the total number of frames of the video file A to be processed is 250 frames, then the calculated number of frames per second of the video file to be processed = 250 frames / 15 seconds = 25 frames / second.

[0067] It should be noted that the video parsing library may be mp4box.js, which is used to extract video track information and audio track information of the video file to be processed.

[0068] As an example, the present application decomposes the video file to be processed into target video files to be processed through a video encoding tool, and converts the target video file to be processed into multiple continuous video frame images through a video decoding tool, thereby converting the video file to be processed into multiple continuous video frame images.

[0069] Exemplarily, the video encoding tool may be EncodeVideoChunk, and the video decoding tool may be VideoDecoder. The video encoding tool EncodeVideoChunk is used to encode the video file to be processed, so as to determine the video data of each frame of the video file to be processed, that is, to obtain the target video file to be processed, wherein the target video file to be processed includes video data of multiple continuous video frame images.

[0070] The video decoding tool VideoDecoder is used to decode video data into image frames. In the present application, it is used to decode video data of multiple consecutive video frame images into multiple consecutive video frame images.

[0071] S202, dividing a plurality of continuous video frame images based on the total video duration and the preset duration to obtain a video frame image group corresponding to each preset duration, wherein the plurality of video frames in the video frame image group are continuous;

[0072] As an example, when the preset duration is 1 second, multiple continuous video frame images can be divided based on the total video duration and the preset duration of 1 second to obtain a video frame image group corresponding to each preset duration of 1 second. Multiple continuous video frame images can also be divided based on the number of frames per second and the total number of frames of the video file to be processed to obtain a video frame image group corresponding to each preset duration of 1 second.

[0073] As another example, when the preset duration is 2 seconds, multiple continuous video frame images can be divided based on the total video duration and the preset duration of 2 seconds to obtain video frame image groups corresponding to each preset duration of 2 seconds. For example, if the total video duration is 20 seconds and the preset duration is 2 seconds, 10 video frame image groups corresponding to the preset duration of 2 seconds are obtained. It should be noted that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0074] S203, for each video frame image group, extracting a plurality of target video frame images from the video frame image group based on a preset interval;

[0075] As an example, the preset interval is pre-set. If the preset interval is not set, a plurality of target video frame images are extracted from the video frame image group based on a default interval.

[0076] Exemplarily, for example, if 5 video frame image groups are obtained based on the video file to be processed, each video frame image group includes 10 video frame images, and taking the preset interval of 2 as an example, 4 target video frame images are extracted from each video frame image group, and 20 target video frame images are extracted based on the video file to be processed.

[0077] For example, if 5 video frame image groups are obtained based on the video file to be processed, each video frame image group includes 10 video frame images, and no preset interval is set, and the default interval is 3, then 3 target video frame images are extracted from each video frame image group based on the default interval, and 15 target video frame images are extracted based on the video file to be processed.

[0078] S204, after drawing a watermark at a preset watermark position of each target video frame image based on a preset text drawing tool, synthesize each target video frame image after drawing the watermark in each video frame image group to generate a GIF file.

[0079] The embodiment of the present application provides a GIF generation method, which analyzes the track information of the video file to be processed based on the video analysis library, determines the total duration of the video, and converts the video file to be processed into multiple continuous video frame images; based on the total duration of the video and the preset duration, divides the multiple continuous video frame images to obtain a video frame image group corresponding to each preset duration, wherein the multiple video frames in the video frame image group are continuous; for each video frame image group, based on the preset interval, extracts multiple target video frame images from the video frame image group; based on the preset text drawing tool, after drawing a watermark at the preset watermark position of each target video frame image, synthesizes each target video frame image after drawing the watermark in each video frame image group to generate a GIF file. This improves the efficiency and security of the video to GIF technology, and further displays the component functions more safely and efficiently through GIF images.

[0080] As an example, Figure 3 As shown, it is a flow chart of another GIF generation method provided in an embodiment of the present application, which draws a watermark at a preset watermark position on each target video frame image based on a preset text drawing tool, including the following steps:

[0081] S301, for each target video frame image, determining a preset watermark position of the target video frame image;

[0082] S302, creating a text box at a preset watermark position based on a preset text drawing tool, and filling in the text box based on a preset watermark naming method;

[0083] S303: Use the filled text box as the watermark of the target video frame image.

[0084] As an example, the target video frame image in the present application may include multiple preset watermark positions, and the multiple preset watermark positions are set at preset distances; the preset watermark positions are set tilted relative to the horizontal direction; the preset watermark naming method is a combination of user code and user name.

[0085] Exemplarily, the preset text drawing tool may be fillText on Canvas, wherein Canvas (Chinese translation: off-screen) is used to edit or modify an image, and fillTex (Chinese translation: fill text) is used to add text content.

[0086] In a specific embodiment, for each target video frame image, multiple preset watermark positions of the target video frame image are determined, taking the default preset watermark position as an example, wherein the default preset watermark position is spaced at a preset distance and is tilted relative to the horizontal direction; a text box is created at the preset watermark position based on fillText, and the text box is filled based on a preset watermark naming method, taking the default preset watermark naming method as an example, the default preset watermark naming method is a combination of a user code and a user name. For example, if the user code is "A1234" and the user name is "Wang Wu", the default preset watermark naming method can be "A1234 Wang Wu". Finally, the filled-in text box is used as the watermark of the target video frame image. It should be noted that the preset watermark position and the preset watermark naming method can be preset by the user, and the preferred embodiment described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0087] In a possible implementation manner, after synthesizing each target video frame image after drawing a watermark in each video frame image group to generate a GIF file, it also includes: after uploading the generated GIF file to an object storage service OSS server, receiving the uniform resource locator URL of the GIF file sent by the OSS server, so that the user can obtain the GIF file based on the URL.

[0088] As an example, each target video frame image after drawing a watermark in each video frame image group is synthesized to generate a GIF file, and then a completion signal of the GIF file generation is obtained based on the gif.on('finished', function(blob){}) method, and the blob (Binary Large Object) data stream of the GIF file is obtained, wherein the blob data stream represents the binary data of the GIF file. After uploading the blob data stream of the GIF file to the OSS server, the uniform resource locator URL of the GIF file sent by the OSS server is received, so that the user can obtain the GIF file based on the URL. The OSS server is an object storage service based on cloud computing, and each object has a unique URL corresponding to it, so that it is used to obtain GIF files based on the URL, thereby improving the efficiency and security of component development.

[0089] It should be noted that the synthesis of each target video frame image after drawing a watermark in each video frame image group can be based on the gif.addFrame method, wherein the gif.addFrame method is used to add each target video frame image after drawing a watermark to the GIF file to be generated, thereby synthesizing the GIF file.

[0090] In a possible implementation, the present application encapsulates the relevant codes of the GIF generation method into an NPM (Node Package Manager) plug-in, and deploys the NPM plug-in to the internal package management platform. Developers or other authorized users can upload the video file to be processed by accessing or referencing the plug-in, thereby obtaining the converted GIF file address, improving the efficiency and security of the video to GIF technology, and then more safely and efficiently displaying the component functions through GIF images, and improving the reusability of related functions and the convenience of development.

[0091] Based on the same inventive concept, the embodiment of the present application also provides a GIF generation device, which has similar principles to the above-mentioned GIF generation method, and the repeated parts will not be repeated.

[0095] The GIF generation module 403 is used to extract multiple target video frame images from the video frame image group based on a preset interval for each video frame image group; based on a preset text drawing tool, after drawing a watermark at a preset watermark position of each target video frame image, each target video frame image after drawing the watermark in each video frame image group is synthesized to generate a GIF file.

This improves the efficiency and security of the video to GIF technology, and further displays the component functions more safely and efficiently through GIF images.

[0097] In some optional implementation manners, the track information parsing module 401 is specifically used for:
