And is not particularly limited herein.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of an information processing method according to the present disclosure is shown. The information processing method comprises the following steps:
In the present embodiment, an execution subject of the information processing method (e.g., a terminal device shown in fig. 1) may send a multimedia parameter acquisition request to a server. And the multimedia parameter acquisition request comprises the multimedia related information of the terminal equipment. In this way, the server can determine the multimedia parameter value corresponding to the multimedia related information. The multimedia-related information is various information related to multimedia. For example, the multimedia-related information may be hardware information, such as CPU information and/or GPU information, or software information or other information, such as system version, package name of application, version, and/or geographical region information (e.g., in which country). The values of the multimedia parameters may be various parameter values which are issued by the server to the terminal device and are related to the multimedia, and are various parameter values required by the terminal device for generating the multimedia file.
Specifically, a plurality of candidate values of each multimedia parameter may be preset on the server, so as to be respectively issued to each terminal device with different multimedia related information. Meanwhile, the corresponding relation between the multimedia related information and the numerical values of the multimedia parameters is also preset on the server, and the numerical values of the multimedia parameters corresponding to different multimedia related information are different. Accordingly, based on the acquired multimedia-related information of the terminal device and the corresponding relationship between the multimedia-related information and the values of the multimedia parameters, the values of the multimedia parameters corresponding to the multimedia-related information can be determined.
In some optional implementations of this embodiment, the multimedia parameters include at least one of: the frame rate of the video, the resolution of the video and the identification of the ear return switch; the hardware information comprises model information and/or geographical region information of the terminal device, and the software information comprises an application identifier and/or version information of the application.
In these alternative implementations, the frame rate of the video may be the frame rate at which the video was produced. The resolution of the video may be the resolution employed when the video is produced and/or when the video is played. Specifically, the identifier of the ear return switch may be a numerical value corresponding to the on state or the off state, such as 1 or 0. The model information here may be a model number. The geographical region information may be a country or a region. The multimedia parameter values corresponding to different model information, geographic area information, application identifiers and application version information may be different.
In some optional implementations of this embodiment, step 201 may include: and calling a network request interface in the software development kit, and sending a multimedia parameter acquisition request for a target application in at least two applications to the server.
In these alternative implementations, the execution subject may send a multimedia parameter acquisition request for one of the at least two applications to the server. Specifically, the execution body may call a network request interface in the software development kit to send a multimedia parameter acquisition request. The target application here may be any one of at least two applications. Then, if the terminal device receives the value of the multimedia parameter returned by the server, the multimedia file can be generated by using the target application and the returned value.
Here, the at least two applications are multimedia-like applications, capable of generating video and/or audio. The server may provide services to the at least two applications simultaneously. In this way, the server can issue parameters for a plurality of applications, rather than only a single application, so as to ensure that the terminal device can produce and generate video and/or audio by using a plurality of applications. For example, there are three applications on the mobile phone of user a, and the server may issue to the mobile phone video parameters required by any one of the three applications, such as application a. Thus, the application a can generate the video by the issued video parameters.
Generating video or audio may include multiple steps, such as capturing video or recording audio, editing, synthesizing, and/or adding special effects to the video or audio, and so forth. Each step has corresponding multimedia parameters.
In this embodiment, the execution agent may receive the value of the multimedia parameter returned by the server, and generate the multimedia file based on the returned value. The multimedia file may include video and/or audio. In practice, the values of the multimedia parameters acquired by the execution body are the values of the parameters required for producing video or audio. The numerical value of the multimedia parameter sent by the server is more suitable for the terminal equipment, and the problems of jamming during generation or overhigh and overlow resolution ratio of the video file and the like caused by unreasonable numerical values of the parameter are prevented.
Specifically, the server may store a corresponding relationship between the value of the multimedia parameter and the multimedia related information, and after receiving the multimedia related information included in the multimedia parameter acquisition request, may determine the value of the multimedia parameter corresponding to the received multimedia related information.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the information processing method according to the present embodiment. In the application scenario of fig. 3, the execution main body 301 may send a multimedia parameter obtaining request 302 to the server, where the multimedia parameter obtaining request includes multimedia-related information of the terminal device, the multimedia-related information is used to indicate information associated with a multimedia file generated by using a target application provided in the terminal device, and the multimedia-related information includes at least one of hardware information and software information of the terminal device; receiving the value 303 of the multimedia parameter returned by the server, and generating a multimedia file 304 based on the value 303 of the multimedia parameter, wherein the value of the multimedia parameter corresponds to the multimedia related information in the multimedia parameter acquisition request.
The method provided by the above embodiment of the present disclosure can determine the value of the multimedia parameter corresponding to the terminal device by uploading the multimedia related information of the terminal device to the server. The same numerical value is not sent to a plurality of terminal devices in a unified mode, and therefore the numerical value of the multimedia parameter sent by the server is suitable for each terminal device. And the terminal equipment can ensure the smooth generation process of the multimedia file and the excellent effect of the generated multimedia file based on the numerical value which is sent by the server and is suitable for the local multimedia parameter.
With further reference to FIG. 4, a flow 400 of yet another embodiment of an information processing method is shown. The flow 400 of the information processing method includes the following steps:
In the present embodiment, an execution subject of the information processing method (e.g., a terminal device shown in fig. 1) can receive a start operation of a target application installed thereto. The start operation may be issued by the user to the terminal device to open the target application.
In this embodiment, in response to receiving a start operation of a target application installed on a terminal device, an execution subject of an information processing method (e.g., the terminal device shown in fig. 1) may send a multimedia parameter acquisition request to a server. And the multimedia parameter acquisition request comprises the multimedia related information of the terminal equipment. In this way, the server can determine the multimedia parameter value corresponding to the multimedia related information. The multimedia-related information is various information related to multimedia.
In this embodiment, the execution agent may receive the value of the multimedia parameter returned by the server, and generate the multimedia file in response to detecting the multimedia file generation operation. The multimedia file generation operation is an operation of generating a multimedia file initiated by a user, and for example, a user may trigger the shooting of a video. When generating a multimedia file, the operation with the highest priority is to generate the multimedia file using the values of the multimedia parameters written in the terminal device. The second operation of the priority is to adopt the value of the multimedia parameter received last time before the target application is started to generate the multimedia file. In addition, if there is no value of the multimedia parameter returned by the server before the target application is started this time or the value is not available, a default value of the local multimedia parameter may be used. Here, the execution agent may call a software development kit to generate a multimedia file.
In some optional implementations of this embodiment, after receiving the value of the multimedia parameter returned by the server in step 403, the method may further include: and storing the received numerical value of the multimedia parameter into a buffer area of the terminal equipment.
In step 403, generating a multimedia file in the target application by using the value of the multimedia parameter received last time before starting the target application may include:
and obtaining the value of the multimedia parameter received for the last time before the target application is started from the cache region, and generating the multimedia file in the target application by using the value of the multimedia parameter obtained from the cache region.
In these optional implementations, the execution main body may store the received values of the multimedia parameters in a buffer, and then may utilize the values of the multimedia parameters at any time, so as to facilitate the generation of a multimedia file by using the values at a later time.
The embodiment may preferentially adopt the value of the multimedia parameter written into the terminal device, and secondly adopt the value of the multimedia parameter received last time before the target application is started this time. After the target application is started, a certain time is often needed from the beginning of receiving the values of the multimedia parameters by the terminal equipment to the end of receiving the values. If a multimedia file is generated by using the latest numerical value of the multimedia parameter, the numerical value of the parameter of the multimedia file may be inconsistent before and after the generation of the multimedia file because the new numerical value of the parameter is received. For example, at the beginning of a video recording, a low resolution is used. And then, if a higher resolution value sent by the server is received, the multimedia file is generated by adopting the higher resolution. Thus, a failure in the generation process may occur due to the fact that the resolution of the recorded video is changed halfway, for example, the video recording fails due to the fact that the terminal equipment cannot be compatible with the two values. Since the value of the parameter written to the terminal device is often set specifically for the terminal device and is suitable for the terminal device, the operation using the written value can be set to the operation of the highest priority.
In this embodiment, the value of the multimedia parameter written in the terminal device is preferentially adopted, and then the value of the multimedia parameter received last time before the target application is started is adopted. Therefore, the value of the parameter for generating the multimedia file is ensured to be suitable for the terminal equipment, and meanwhile, the condition that the multimedia file is generated unsuccessfully is prevented, and the multimedia file is ensured to be generated smoothly.
