[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In a typical configuration of the present application, the terminal and the equipment of the service network each include one or more processors (CPU), input / output interface, network interface and memory.

[0021] The memory may include non-permanent storage in a computer-readable medium, random access memory (RAM) and / or non-volatile memory in the form of read-only memory (ROM) or flash RAM. The memory is an example of a computer-readable medium.

[0022] Computer readable media include permanent and non-permanent, removable and non-removable media, and can be implemented by any method or technology to store information. Information can be computer program instructions, data structures, modules of programs or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, read-only compact disk (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device.

[0023] In actual scenarios, the execution subject of the method can be an object device, or a device formed by integrating an object device and a network device through a network, or an application running on the above device. The object device includes but is not limited to various terminal devices such as computers, mobile phones, tablet computers, smart watches, and bracelets. The network device includes but is not limited to network hosts, single network servers, multiple network server sets, or cloud computing-based computer sets. Here, the cloud is composed of a large number of hosts or network servers based on cloud computing, where cloud computing is a type of distributed computing, a virtual computer composed of a group of loosely coupled computer sets.

[0024] As discussed above, how to improve the scalability and maintainability of the player under the conditions of multiple platforms, multiple devices, and multiple scenarios is worthy of attention and an urgent need.

[0025] In some solutions, the functions of the player are generally organized and written in a process-oriented or object-oriented manner. After going deep into the media processing process, it is found that its essence is that the data state is bound to each function. Or some players are componentized, but they only componentize some core functions.

[0026] In this way, the data state is bound to each function, and when a data structure or a function needs to be modified, the modification cost will be very high. The dynamic expansion capability of componentized players will be relatively weak, that is, the cost of replacing a method in a component or replacing the component is very high.

[0027] In this regard, an embodiment of the present application provides a method for playing files. When receiving a play request for a target file, the method first determines the operation information corresponding to the play request, then determines the target operation module corresponding to the operation information from a predefined set of operation modules, and uses the target operation module to play the target file. Thus, the function module corresponding to the user's play request is used to play the target file, thereby realizing user personalized playback, and separating data from operations, so that the data structure and operation logic can be independently expanded and modified without affecting each other, thereby improving the scalability of the player.

[0028] When the execution subject is software, it can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules, or as a single software or software module, and no specific limitation is made here.

[0029] It should be understood that in the technical solutions involved in this application, the acquisition, storage, use, processing, transportation, provision and disclosure of the personal information of the subjects involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0030] Figure 1 A process 100 for playing a file provided by an embodiment of the present application is shown. The process 100 includes at least the following processing steps:

[0031] (Step) S101, in response to receiving a play request for a target file, determining operation information corresponding to the play request.

[0032] In the embodiments of the present application, illustratively, in the case where the execution subject is, for example, a server used by a service provider of a platform, a user requesting to play a file can communicate with the execution subject through the terminal device used by the user to play the file (for example, play music, play video, etc.). It should be understood that the selection of the above execution subject is only for exemplary needs. In some scenarios, the execution subject may also be a terminal device used by the user, so that the user can play the file locally.

[0033] Here, the terminal device generally displays multiple files, and the user can select the file that he wants to operate or play from the multiple files, that is, the target file. And the user can select the target file by double-clicking, and at the same time generate a play request for the target file, and send the play request to the execution subject. It should be noted that each file is stored independently.

[0034] After receiving the play request for the target file, the execution subject will determine the operation information corresponding to the play request, wherein the operation information includes the play operation, synchronization operation and / or decoding operation of the target file. Since the target file here can be a music file, a video file, or other operable files, the operation information here refers to the operation required to achieve the playback of the file. As an example, when the target file is a music file, the operation corresponding to the play request is the music playback operation. When the target file is a video file, the operation corresponding to the play request is the video playback operation and the audio and video synchronization operation. When the target file is other files, the operation corresponding to the play request can also include preloading operations and the like. In addition, the operation corresponding to the play request can also be a decoding operation of the target file, and further, when the target file is a music file, it can be a decoding operation of the music file. When the target file is a video file, it can be a decoding operation of the audio of the video file, or a decoding operation of the video of the video file.

[0035] In some embodiments, the operation information includes: a preloading operation, a playing operation and / or a media reading operation. The preloading operation is used to implement the preloading function of the target file. The playing operation is used to implement the playing of the target file, such as the playing of a music file or the playing of a video file. The media reading operation is used to read a media file. When playing different types of target files, the operations to be performed are different, and the execution subject will determine the operation information corresponding to the playing function according to the type of the target file.

[0036] S102: Determine a target operation module corresponding to the operation information from a predefined operation module set.

[0037] In the embodiment of the present application, the execution subject predefines an operation module set, that is, modularizes each operation function. That is, the operation module set includes multiple operation modules, and each operation module corresponds to an operation function.

[0038] For example, the music playing module has the function of playing music, the video playing module has the function of playing videos, and so on.

[0039] After determining the operation information corresponding to the play request based on the above step S101, the execution subject will determine the operation module corresponding to the operation information from the operation module set, that is, the target operation module, which can be one or more, corresponding to the operation information. That is, the target operation module can be a play module, a synchronization module, a decoding module, a preprocessing module, etc.

[0040] In some embodiments, the target file is a music file, and accordingly, the operation information is a music playing operation, that is, in response to receiving a music playing request for a music file, the execution subject determines that the operation information corresponding to the music playing request is a music playing operation. Then, the execution subject determines the music playing module corresponding to the music playing operation from a set of predefined operation modules. Since the operation information corresponds to the operation module, after determining the operation information, the operation module corresponding to the operation information can be determined. Thus, the music operation module for playing music is determined from the predefined operation modules.

[0041] In some embodiments, the target file is a video file, and accordingly, the operation information is a video playback operation. Since the video file includes audio data and video data (i.e., picture data), in the process of playing the video file, an audio-video synchronization operation is also involved, and the audio-video synchronization operation is used to synchronize the audio data with the corresponding video data. That is, in response to receiving a video playback request for a video file, the execution subject determines that the operation information corresponding to the video playback request is a video playback operation and an audio-video synchronization operation. Then, the execution subject determines the video playback module corresponding to the video playback operation and the audio-video synchronization module corresponding to the audio-video synchronization operation from a predefined set of operation modules. Since the operation information corresponds to the operation module, after determining the operation information, the operation module corresponding to the operation information can be determined. Thus, the operation module for playing the video is determined from the predefined operation modules.

[0042] Furthermore, when the target file is a video file, the operation information may be a video decoding operation, specifically, decoding the audio of the video file or decoding the video of the video file.

[0043] S103: Use the target operation module to play the target file.

[0044] In an embodiment of the present application, after the execution subject determines the target operation module based on the above S102, the target operation module is used to play the target file. That is, the target file is input into the target operation module, and the target operation module can play it. For example, a music file is input into the music playing module, and the music playing module can play the music.

[0045] It should be noted that the file content in this embodiment is stored in an independent area, but there is no operation in this area. All operations are in different modules. Different modules take different operations according to different functions. For example, the preloader is the preloading operation, and the player is the playback operation. Different components only need to perform the established operations according to the current state and data to play the file, so as to meet the needs of different scenarios and improve scalability. And because the data is stored in an independent area, each module is also independent, so the corresponding data structure or functional module can be modified according to actual needs without affecting each other, thereby increasing flexibility and reducing maintenance costs.

[0046] In some embodiments, the execution subject will use the video playback module to play the audio and video of the video file. Since the pre-defined functional module integrates a multi-layer structure that can realize the function, the encapsulated module can fully realize its corresponding function. The video file is input into the video playback module, and the video playback module can realize the playback of the video, specifically the audio and video of the video. Then the video file is input into the audio and video synchronization module, and the audio and video synchronization module can ensure that the audio and video are played synchronously. Thus, the video file is played using the functional module corresponding to the operation information.

[0047] In some embodiments, the play request includes the file format information of the target file, and accordingly, the operation information corresponding to the play request includes a decoding operation for the target file, and the target operation module corresponding to the operation information includes a decoding module that matches the file format information. The file format (or file type) refers to a special encoding method for information used to store information. Here, the execution subject obtains the file format of the target file in the play request and determines a decoding module that matches the file format, thereby accurately and quickly decoding the target file.

[0048] Correspondingly, the execution subject will also use the decoding module to decode the target file. When the target file is a music file, the music decoding module can be used to decode the music file; when the target file is a video file, the video decoding module can be used to decode the video file. This facilitates the subsequent playback of the target file.

[0049] In some embodiments, when the target file is a video file, the decoding module includes: an audio decoding module and a video decoding module. When decoding, the audio of the video file can be decoded by the audio decoding module; and the video of the video file can be decoded by the video decoding module. Since the video file includes both audio data and video data (i.e., picture data), before playing the video file, the audio and video of the video file need to be decoded by the audio decoding module and the video decoding module. This facilitates the subsequent playback of the video file.

[0050] The method for playing files provided in the present application can use a functional module corresponding to the user's playback request to realize the playback of the target file, thereby realizing user personalized playback and separating data from operations, so that the data structure and operation logic can be independently expanded and modified according to actual scenario requirements without affecting each other, thereby improving the scalability and maintainability of the file playback method.

[0051] Figure 2 A process 200 for playing a file provided by another embodiment of the present application is shown. The process 200 at least includes the following processing steps:

[0052] S201, in response to receiving a play request for a target file, determining target performance information corresponding to the play request.

[0053] Specifically, in this embodiment, the terminal device generally displays multiple files, and the user can select the file that he wants to operate or play from the multiple files, that is, the target file. And the user can select the target file by double-clicking, and at the same time generate a play request for the target file, and send the play request to the execution subject. When the execution subject receives the play request for the target file, it will first determine the target performance information corresponding to the play request.

[0054] Since the present embodiment has separated data from operations, different operations are combined into an externally available presentation layer to achieve the corresponding functions. The above target presentation information refers to the presentation layer information corresponding to the function of the play request. For example, the target presentation information corresponding to the music play request is music play; the target presentation form corresponding to the video play request is video play.

[0055] S202: Determine target operation information corresponding to the target performance information based on a predefined relationship comparison table.

[0056] It should be understood that in this step, the execution subject can determine the target operation information corresponding to the target performance information based on a predefined relationship comparison table. Here, after encapsulating multiple functional modules, the correspondence between the performance information and the operation information of each functional module will be defined, thereby obtaining a relationship comparison table. After determining the target performance information corresponding to the play request, the operation information corresponding to the target performance information, that is, the target operation information, will be determined according to the relationship comparison table. For example, the target operation information corresponding to music playback is the music playback operation; the target operation information corresponding to video playback is the video playback operation and the audio and video synchronization operation. Thereby, the operation information corresponding to the play request is accurately determined.

[0057] S203: Determine a target operation module corresponding to the operation information from a predefined operation module set.

[0058] In an embodiment of the present application, the execution subject will predefine an operation module set, that is, modularize each operation function. That is, the operation module set includes multiple operation modules, and each operation module corresponds to an operation function. For example, the music playback module has the function of playing music, the video playback module has the function of playing videos, and so on. After determining the operation information corresponding to the playback request based on the above step S202, the execution subject will determine the operation module corresponding to the operation information from the operation module set, that is, the target operation module. The target operation module can be one or more, which corresponds to the operation information. For example, the music playback operation corresponds to the music playback module, the video playback operation corresponds to the video playback module, and the audio and video synchronization operation corresponds to the audio and video synchronization module.

[0059] S204: Use the target operation module to play the target file.

[0060] In an embodiment of the present application, after the execution subject determines the target operation module based on the above S203, the target operation module will be used to play the target file. That is, the target file is input into the target operation module, and the target operation module can play it. For example, a music file is input into the music playing module, and the music playing module can play the music.

[0061] S205: Perform control operations on the file being played.

[0062] In the embodiment of the present application, the execution subject will perform control operations on the file being played, wherein the control operations include: pausing, stopping, fast forwarding or rewinding. That is, the playing of the file being played can be controlled. Specifically, the terminal device can provide corresponding control buttons, and the user can click the buttons to pause the playing of the file being played, stop the playing of the file being played, fast forward or rewind the playing of the file being played. Thus, the playing control management of the file being played is realized.

[0063] The method for playing files provided in this embodiment, when receiving a play request for a target file and determining the target performance information corresponding to the play request, first determines the target performance information corresponding to the play request, and then determines the target operation information corresponding to the target performance information based on a predefined relationship comparison table; then determines the target operation module corresponding to the operation information from a predefined set of operation modules, and uses the target operation module to play the target file, and can also control the file being played. Thus, by separating data from operations, the data structure and the operation logic can be independently expanded and modified, which improves the scalability and flexibility of the file playing method and reduces the maintenance cost of the file playing method.

[0064] To deepen understanding, this application also provides a specific implementation solution in combination with a specific application scenario. Figure 3 , Figure 3 A schematic diagram of a process 300 of playing a file in an application scenario provided by an embodiment of the present application. In the process 300, for example, a server 310 may play the file.

[0065] Specifically, for example, the user 320 communicates with the server 310 and executes S301 to request the server 310 to play a video file. Accordingly, the server 310 can respond to this, obtain the video file to be played, that is, the target file, and generate a play request for the target file, and execute S302 to determine the operation information corresponding to the video play request, where the operation information includes a video play operation and an audio and video synchronization operation.

[0066] Then, the server 310 executes S303 to determine a video playback module corresponding to the video playback operation and an audio and video synchronization module corresponding to the audio and video synchronization operation from a predefined set of operation modules.

[0067] Then, the server 310 executes S304, plays the audio and video of the video file using the video playback module, and synchronizes the audio and video using the audio and video synchronization module.

[0068] In this application scenario, the file content is stored in an independent area, but there is no operation in this area. All operations are in different modules. Different modules take different operations according to different functions, that is, the video playback module is the video playback operation. Therefore, the file can be played according to the function modules corresponding to all the operations of the playback request.

[0073] In some embodiments, the synchronization module determines that the subunit is further configured to play the audio and video of the video file using the video playback module; and synchronize the audio and video using the audio and video synchronization module.

[0074] In some embodiments, the playback request includes file format information of the target file, the decoding module is a module matching the file format information; and the playback unit includes: a decoding submodule configured to use the decoding module to perform a decoding operation on the target file.

[0075] In some embodiments, the target file includes a video file, and the decoding module includes: an audio decoding module and a video decoding module; and the decoding submodule is further configured to use the audio decoding module to decode the audio of the video file; and use the video decoding module to decode the video of the video file.
