Fig. 1 is a flowchart illustrating a method for generating a video file according to an embodiment of the present invention, where the method includes:
step S110: and acquiring video template information and video material information contained in the video generation request.
Specifically, when a video generation request sent by a user is received, the video generation request is analyzed to obtain video template information and video material information contained in the video generation request. The video template information may be specific content of the video template, or may only be identification information of the video template. The video template is used for setting an editing processing mode of a video, and specifically comprises a video format, character information, special effect information and the like. The video material information is the original material to be processed, and may specifically be the specific content of the video material, or may only be the identification information of the video material.
Step S120: and generating a video rendering task corresponding to the video generation request according to the video template information and the video material information, and storing the generated video rendering task into a preset task queue.
Specifically, a video rendering task corresponding to the video generation request is generated, and corresponding video template information and video material information are recorded in the video rendering task. Since the number of the video generation requests may be multiple, in order to manage the video rendering tasks corresponding to the video generation requests, in this embodiment, a task queue is provided. The task queue is used for orderly storing each video rendering task so as to realize the orderly scheduling of each video rendering task.
Step S130: and determining a video rendering task to be rendered according to the task queue, and loading video template content and video material content corresponding to the video rendering task to be rendered.
Specifically, the video rendering tasks to be rendered may be sequentially obtained from the task queue in a first-in first-out order. Or different priorities can be set for each video rendering task, so that the video rendering tasks are acquired according to the priorities.
And determining corresponding video template information and video material information aiming at the video rendering task to be rendered, and correspondingly loading video template contents corresponding to the video template information and video material contents corresponding to the video material information.
Step S140: and rendering the video material content according to the video template content to generate a video file corresponding to the video generation request.
Specifically, a corresponding editing processing mode, such as special effects, characters and the like, is determined according to the content of the video template, and the content of the video material is rendered according to the content of the video template to obtain a video file corresponding to the content of the video material.
Therefore, the mode can uniformly process the generation process of the plurality of video files, each video rendering task is managed through the task queue, a user only needs to upload the template and the material corresponding to each video rendering task, the user does not need to render each video one by one in real time, and the video rendering efficiency is improved. In addition, the multiplexing of the video editing processing mode can be realized through the video template information, so that the defect that the video editing mode is set for each material one by one is avoided, and the processing efficiency is greatly improved.
Fig. 2 is a flowchart illustrating a method of generating a video file according to another embodiment of the present invention. As shown in fig. 2, the method includes:
step S200: the method comprises the steps of configuring a plurality of video templates in advance, and storing the video templates in a preset video template library.
The video template is used for setting a specific mode of executing editing processing on the video material, such as adding music, pictures, characters, animation and the like. In this embodiment, the video template may be a project file in a video processing application, where the project file includes: material subfiles and non-material subfiles. Wherein, the material subfile is used for providing pending material information, and non-material subfile is the file except that material information, includes: format files, special effects files, etc.
In this step, a plurality of video templates are configured in advance, each video template corresponds to a different editing processing mode, and types of video materials corresponding to the video templates may be different from each other. Accordingly, the corresponding video material types need to be configured for the respective video templates. And storing each video template into a preset video template library for subsequent calling. The video template can be used for multiplexing aiming at the editing processing mode, so that the processing efficiency is greatly improved.
Step S210: and acquiring video template information and video material information contained in the video generation request.
Specifically, a user may generate and send a video generation request through a client device. For example, the required video template is selected through a template selection entry shown in the client interface, and the required video material is uploaded through a material uploading entry shown in the client interface. In one specific example, a user sends a video generation request through an applet or application or the like of a client: and selecting a proper video template by a user on a front-end interface, and uploading corresponding small videos or pictures as video materials according to the material types adapted to the video template. And after the uploading is completed, calling the server interface to send to the server.
The video template information in the video generation request may be a template identifier of a video template stored in a video template library. Accordingly, the video template selected by the user through the template selection inlet is the template existing in the video template library. Or, the user may also create a video template in this step, and store the video template created by the user in the video template library to dynamically expand the video template library, which is not limited in the present invention.
Correspondingly, the execution main body of the step is the server, and when the server receives a video generation request sent by the client, the server analyzes the video generation request to acquire the video template information and the video material information contained in the video generation request. The video template information may be specific content of the video template, or may only be identification information of the video template. The video template is used for setting an editing processing mode of a video, and specifically comprises a video format, character information, special effect information and the like. The video material information is the original material to be processed, and may specifically be the specific content of the video material, or may only be the identification information of the video material.
Step S220: and generating a video rendering task corresponding to the video generation request according to the video template information and the video material information, and storing the generated video rendering task into a preset task queue.
Specifically, the server generates a video rendering task corresponding to the video generation request, and the video rendering task records corresponding video template information and video material information. Since the number of the video generation requests may be multiple, in order to manage the video rendering tasks corresponding to the video generation requests, in this embodiment, a task queue is provided. The task queue is used for orderly storing each video rendering task so as to realize the orderly scheduling of each video rendering task.
In a specific example, after receiving a video generation request, the server performs business logic processing such as warehousing so as to generate a video rendering task and push the video rendering task to a task queue.
Step S230: and determining a video rendering task to be rendered according to the task queue, and loading video template content and video material content corresponding to the video rendering task to be rendered.
Specifically, the video rendering tasks to be rendered may be sequentially obtained from the task queue in a first-in first-out order. Or different priorities can be set for each video rendering task, so that the video rendering tasks are acquired according to the priorities. And determining corresponding video template information and video material information aiming at the video rendering task to be rendered, and correspondingly loading video template contents corresponding to the video template information and video material contents corresponding to the video material information.
In this embodiment, in order to improve the task processing efficiency, the processing is performed in a multi-process parallel processing manner: and acquiring a plurality of video rendering tasks to be rendered from the task queue, and respectively loading video template contents and video material contents corresponding to the video rendering tasks to be rendered through a plurality of parallel processing processes. Specifically, in order to increase the processing speed, a plurality of video rendering tasks to be rendered are acquired at one time, and the plurality of video rendering tasks to be rendered can be directly acquired according to the storage sequence, or can be acquired by combining with the task priority. Correspondingly, a plurality of concurrent processing processes are started, and the concurrent processing of a plurality of rendering tasks is carried out in a multi-process processing mode. Each process is used for loading video template content and video material content corresponding to a video rendering task corresponding to the process.
Specifically, when loading the video template content and the video material content corresponding to the video rendering task, in order to increase the processing speed and prevent errors, in this embodiment, the obtained video template content and the obtained video material content are further copied to the preset work area. Wherein the preset working area is exclusively used for storing the video rendering task to be rendered.
In addition, in this step, the video template content and the video material content corresponding to the video rendering task to be rendered may be loaded from the video template library. Or, the video material content may be stored in the video material library in advance, so as to load the corresponding video material content from the video material library, and the specific details are not limited in the present invention.
Step S240: and rendering the video material content according to the video template content to generate a video file corresponding to the video generation request.
Specifically, a corresponding editing processing mode, such as special effects, characters and the like, is determined according to the content of the video template, and the content of the video material is rendered according to the content of the video template to obtain a video file corresponding to the content of the video material.
In this embodiment, in order to increase the rendering speed, rendering is performed in a multi-thread parallel processing manner:
first, the video template content and/or the video material content is divided into a plurality of partial contents. For example, the text effect, the animation effect, the background effect, and the like in the content of the video template may be respectively used as one local content. As another example, the video material content may be divided into a plurality of partial contents by the number of materials or time points of the materials. In short, the video template content and/or the video material content can be split into a plurality of pieces by dividing the local content in advance, so that multithreading parallel processing is facilitated.
Then, starting a plurality of rendering threads which work in parallel, wherein each rendering thread corresponds to the local content in the video template content and/or the video material content respectively; each rendering thread respectively acquires local content in the video template content and/or the video material content, and performs rendering processing according to the acquired local content. Specifically, each rendering thread rapidly renders the corresponding local content in a parallel manner, so that the rendering operation of the whole material is completed together through the cooperation of multiple threads.
In addition, when the preset working area is set, each rendering thread acquires the video template content and/or the local content in the video material content from the preset working area respectively. The preset working area is specially used for storing the templates and the materials corresponding to the tasks being rendered, and the templates and the materials corresponding to the tasks which have completed the rendering operation are moved out of the working area, so that the rendering thread does not need to execute searching operation, the content can be directly acquired from the preset working area, the operation is convenient and fast, and errors are not easy to occur.
The rendering process mainly comprises the following operations: first, the corresponding template content is downloaded, namely: ae (after effects) project file. The template is then copied to a new workspace (in order to enable multitasking rendering), and the template material file under the AE project is replaced with the user's material. Next, aerender. exe rendering is invoked to render into video. Finally, the transcoded video is compressed using ffmpeg.
Therefore, when the video template is a project file in a video processing application, and the project file comprises a material subfile and a non-material subfile, in this step, the rendering processing is performed in the following manner: and determining a material subfile contained in the video template content, and replacing the material subfile with the video material content and then executing rendering processing.
Step S250: and pushing the video file to a corresponding client.
Specifically, the generated video files are stored in a preset video queue, and the mapping relation between each video file and the corresponding client is recorded in the video queue; and pushing each video file in the video queue to the corresponding client according to the mapping relation.
In one particular example, this step is performed by a rendering service that consumes a task queue to obtain tasks; and analyzing the information of the task to load the template and the material, rendering the template and the material into a video, and pushing a rendering result to a video queue. Correspondingly, the server consumes the video queue and pushes the generated video information to the client, wherein the generated video information comprises a timeout and retry mechanism, and the whole process is completed.
In conclusion, the mode can uniformly process the generation process of a plurality of video files, each video rendering task is managed through the task queue, a user only needs to upload the template and the material corresponding to each video rendering task, the user does not need to render each video one by one in real time, and the video rendering efficiency is improved. In addition, the multiplexing of the video editing processing mode can be realized through the video template information, so that the defect that the video editing mode is set for each material one by one is avoided, and the processing efficiency is greatly improved. In addition, the video generation mode provided by the invention can reduce manual intervention, and aims at automatic synthesis rendering of the video template and multitask automatic operation. The operation only needs to upload the video template without other operations, and the Windows cluster can realize automatic rendering and multitask processing and improve the rendering speed.
In addition, various modifications and changes may be made by those skilled in the art to the above-described embodiments. For example, in one variation, the front end implements special effects using CSS and JS. In another variant, a template is developed by using an open-source tool such as an MLT Multimedia Framework, and the rendering of a video by a server is realized. In a word, the Windows cluster in the scheme utilizes the video template and uses AE to conduct automatic video rendering.
