Description

Technical Field

[0001] The present invention belongs to the technical field of audio and video transcoding, and in particular relates to a method, device, equipment and storage medium for obtaining a universal transcoding template. Background Art

[0002] The basic process of transcoding: first configure the encoding template, then send the parameters in the encoding template to the transcoding service for splicing the transcoding command line. After the command line splicing is completed, it is handed over to the engine service to execute the command line.

[0003] Currently, these different products all use their own product-specific encoding templates, transcoding services, and engine services. Whenever transcoding is required, the encoding templates specific to each product must be configured first, and the encoding templates configured in one product cannot be used in other products. When other products want to use the encoding templates, they need to separately configure the dedicated encoding templates used by their own products. Due to the inconsistency of the encoding templates of various audio and video processing tools, the various transcoding parameters that need to be configured in the encoding templates are also not unified. In addition, each audio and video processing tool uses its own dedicated transcoding service and engine service. As a result, the transcoding process in one product cannot be fully applied to another similar product. For example:

[0004] In virtual live streaming, you first need to create a new virtual live streaming task and then configure a dedicated encoding template for virtual live streaming. The encoding template parameters include common audio and video parameters as well as various virtual live streaming-specific parameters. After configuring the encoding template and starting the task, the parameters in the encoding template are sent to the dedicated transcoding service for virtual live streaming to assemble the transcoding command lines. The virtual live streaming transcoding service can only assemble the dedicated transcoding command lines based on the characteristics of virtual live streaming. Once the command lines are assembled, they are executed by the dedicated engine for virtual live streaming.

[0005] For online transcoding, the process for using encoding templates is similar to that for virtual live streaming. You must first create a new online transcoding task and configure a dedicated encoding template. This template includes common parameters such as audio and video, as well as some specific parameters for online transcoding. After the task is started, the parameters in the encoding template are sent to the dedicated transcoding service. The transcoding service then assembles the online transcoding command line and sends it to the dedicated engine for execution.

[0006] Therefore, if a modification is made to the dedicated encoding template in a virtual live broadcast product, and a similar modification is required in another product, such as online transcoding, the dedicated encoding template in online transcoding must also be modified. This fully coupled structure of encoding templates and products increases development costs and reduces development efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide a method, device, equipment and storage medium for obtaining a universal transcoding template to solve the problems of inconsistent transcoding parameters and transcoding engines in different products and each audio and video processing tool can only use its own encoding template.

[0008] In order to solve the above problems, the technical solution of the present invention is:

[0009] A method for obtaining a universal transcoding template, comprising:

[0010] Bringing together a variety of audio and video processing tools, decoupling the business and logical data related to the encoding template, and integrating them to obtain encoding template services including audio parameters, video parameters, image processing parameters, watermark parameters, graphic layout parameters, and background image parameters;

[0011] Optimize and integrate the transcoding services of multiple audio and video processing tools, identify different audio and video processing tools, and give each audio and video processing tool a unique identification code to facilitate transcoding service identification and select the corresponding command line splicing method;

[0012] Optimize and unify the engine services of multiple audio and video processing tools to execute command lines from them;

[0013] The encoding template service, transcoding service and engine service are combined to obtain a universal transcoding template.

[0014] Among them, various audio and video processing tools include virtual live broadcast tools, online transcoding tools, offline transcoding tools and recording tools.

[0015] When transcoding during a live broadcast, perform the following steps:

[0016] Create a new live broadcast task;

[0017] Call the encoding template service API through the general transcoding template management web page to create a new encoding template and save it to the encoding template service;

[0018] After the live broadcast task is started, the encoding template service sends the parameters in the encoding template to the transcoding service;

[0019] The transcoding service identifies and confirms that it is live transcoding based on the identification code in the parameter, generates a command line in the live transcoding mode, and sends it to the engine service;

[0020] The engine service recognizes and executes the command line.

[0021] Based on the same concept, a device for obtaining a universal transcoding template is provided, comprising:

[0022] The encoding template integration module is used to integrate multiple audio and video processing tools, decouple the business and logical data related to the encoding template, and integrate them to obtain encoding template services including audio parameters, video parameters, image processing parameters, watermark parameters, graphic layout parameters, and background image parameters;

[0023] The transcoding service optimization module is used to optimize and integrate the transcoding services of various audio and video processing tools. Different audio and video processing tools are identified, and each audio and video processing tool has a unique identification code to facilitate the transcoding service to identify and select the corresponding command line splicing method;

[0024] The engine service optimization module is used to optimize and unify the engine services of multiple audio and video processing tools to execute command lines from multiple audio and video processing tools.

[0025] A device comprising:

[0026] A memory and a processor, wherein instructions are stored in the memory and the memory and the processor are interconnected via a line;

[0027] The processor calls the instruction in the memory to implement the method for obtaining a universal transcoding template in an embodiment of the present invention.

[0028] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements a method for obtaining a universal transcoding template in an embodiment of the present invention.

[0029] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0030] A method for obtaining a universal transcoding template in one embodiment of the present invention optimizes the parameters of the encoding templates in various audio and video processing tools, flexibly integrating the common and specific parameters in the encoding templates of each audio and video processing tool into unified encoding template parameters that can be used in multiple audio and video products. The transcoding services of each audio and video processing tool are optimized and integrated, optimizing and integrating the transcoding parameters and transcoding command line splicing methods of different products to enable the transcoding services to adapt to different products. The engine services are optimized and unified, enabling the engine services to distinguish and execute command lines from different products. By optimizing and unifying transcoding parameters, transcoding services, and engine services, encoding templates can be shared across multiple audio and video products. This structure enables encoding templates created in one product to be used in multiple products. The source of encoding templates in a product is no longer limited to that product; they can also be from encoding templates created in other products, making it more convenient, flexible, and open. Furthermore, from a development perspective, since encoding templates can be shared, changes to encoding templates can be applied to multiple products simultaneously, simplifying development, improving development efficiency, and facilitating maintenance.

[0035] The following is a detailed description of a method, device, apparatus, and storage medium for obtaining a universal transcoding template proposed by the present invention, in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0036] Example 1

[0037] This embodiment provides a method for obtaining a general transcoding template. Figure 1 The method for obtaining the universal transcoding template includes the following steps:

[0038] S1: Brings together multiple audio and video processing tools, decouples and integrates the business and logical data related to the encoding template to obtain the encoding template service including audio parameters, video parameters, image processing parameters, watermark parameters, graphic layout parameters, and background image parameters;

[0039] S2: Optimize and integrate the transcoding services of multiple audio and video processing tools. Different audio and video processing tools are identified, and each audio and video processing tool has a unique identification code to facilitate the transcoding service to identify and select the corresponding command line splicing method.

[0040] S3: Optimizes and unifies the engine services of multiple audio and video processing tools to execute command lines from multiple audio and video processing tools.

[0041] In step S1, the encoding templates in each audio and video processing tool are decoupled to form a separate service and optimized to become an encoding template service that can be shared by multiple audio and video products.

[0042] Decoupling: Currently, the business logic related to encoding templates in each tool is integrated with the business itself. Decoupling means separating the business and logic related to encoding templates from each audio and video processing tool.

[0043] Integrate the encoding templates of different tools into a shared encoding template: Some of the encoding templates of various audio and video processing tools are universal, such as video and audio parameters. However, some parameters are unique to each audio and video processing tool, such as image processing parameters, watermark parameters, graphic layout parameters, and background image parameters. Integration is achieved by placing the common and unique parameters of these audio and video processing tools into a shared encoding template. Specifically, the encoding template-related services and logic of each audio and video processing tool are extracted to form a separate encoding template service that can be applied to each audio and video processing tool. The parameters in the integrated shared encoding template include: video parameters, audio parameters, image processing parameters, watermark parameters, graphic layout parameters, and background image parameters.

[0044] In step S2, the transcoding services of various audio and video processing tools are optimized and unified so that the command line splicing method is applicable to a variety of audio and video products. The transcoding service is responsible for converting the input, encoding, and output parameters of the task into commands that the engine can recognize. Since various audio and video products use the same database fields, such as audio bitrate is audioBitRate, the command lines spliced by the transcoding service are all "-b:a". The difference is that different products have their own unique fields, such as recording products have recording duration fields. Virtual live broadcast products have fields unique to virtual live broadcasts. In addition, when calling the transcoding service, the transcoding service will be informed of which product the operation is to be executed from, through an enumeration (or identifier) such as virtual live broadcast / recording / online transcoding, the transcoding service will generate the corresponding command based on this enumeration value. Therefore, the transcoding service can be unified for various audio and video products.

[0045] In step S3, the engine services of various audio and video processing tools are optimized and unified, enabling them to execute command lines from a variety of audio and video products. The engine services include transcoding, recording, and other functions that support multiple products. As long as each audio and video product splices commands according to the engine service's specifications, the engine services will recognize and execute the corresponding functions. Therefore, the engine services can be unified across audio and video products.

[0046] Application Examples

[0047] When creating tasks in various audio and video processing tools, you can obtain shared encoding templates through the shared encoding template service. Encoding templates created in each tool are automatically saved to the shared encoding template service.

[0048] After starting their respective tasks, the unified transcoding service will assemble the transcoding command lines required by the corresponding products according to different products, and then hand them over to the unified engine service to execute the command lines.

[0049] Please see Figure 2 The products that use the shared encoding template service include: virtual live broadcast, online transcoding, offline transcoding and recording system.

[0050] The services included in the following process descriptions are: Encoding Template Service, Transcoding Service, and Engine Service.

[0051] Use a common encoding template workflow in virtual live broadcasts:

[0052] 1. Create a new virtual live broadcast task;

[0053] 2. By calling the API of the coding template service through the coding template management WEB page, you can create a new shared coding template and use it. The newly created coding template will be automatically saved to the coding template service. You can also directly obtain the shared coding template through the import function.

[0054] 3. After the task is started, the parameters in the encoding template are sent to the unified transcoding service, which splices the transcoding command line. The transcoding service generates transcoding command lines containing different parameters based on different products. In this example, the transcoding service generates command lines based on virtual live broadcasting.

[0055] 4. The engine service recognizes and executes the command line.

[0059] Transcoding service optimization module 2 is used to optimize and integrate the transcoding services of multiple audio and video processing tools, identify different audio and video processing tools, and give each audio and video processing tool a unique identification code to facilitate the transcoding service to identify and select the corresponding command line splicing method;

[0060] Engine service optimization module 3 is used to optimize and unify the engine services of multiple audio and video processing tools to execute command lines from multiple audio and video processing tools.
