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 this embodiment, an execution subject of the information processing method (e.g., a server shown in fig. 1) may receive a multimedia parameter acquisition request sent by a terminal device. And the multimedia parameter acquisition request comprises the multimedia related information of the terminal equipment. Thus, the executing body can determine the value of the multimedia parameter matched with 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 may be software information or other information, such as a system version, a package name of an application, a version of an application, and/or geographical area information (e.g., which country the terminal device is located in) of the terminal device.
In some optional implementations of this embodiment, the multimedia parameters include at least one of: a frame rate of the video, a resolution of the video, and an identification of the earreturn switch.

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.
In some optional implementation manners of this embodiment, the hardware information includes model information and/or geographic area information where the terminal device is located, and the software information includes an identifier of the application and/or version information of the application.
In these alternative implementations, the model information may be a number of the model. 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 this embodiment, the execution subject may determine the value of the multimedia parameter matching the multimedia related information from preset values of candidate multimedia parameters. 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 the values of various parameters required by the terminal device for generating the multimedia file.
In practice, the values of the multimedia parameters that match the multimedia-related information may be determined in various ways.

Meanwhile, the corresponding relationship between the multimedia related information and the numerical values of the multimedia parameters can be preset, and the numerical values of the multimedia parameters corresponding to different multimedia related information are different. Therefore, 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 matching the multimedia-related information can be determined. In addition, the corresponding relation can be utilized to screen out the numerical values of a plurality of multimedia parameters. And one of the values is selected or an average value is taken by using a preset rule, and the value of the multimedia parameter is determined to be used as the value of the multimedia parameter matched with the multimedia related information.
In this embodiment, the execution subject may return the determined value of the multimedia parameter to the terminal device, so that the terminal device generates the multimedia file based on the returned value. The multimedia file may include video and/or audio. In particular, the values of the multimedia parameters are the values of the parameters required for making video or audio.

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, an execution body 301 may receive a multimedia parameter obtaining request 302 sent by a terminal device, where the multimedia parameter obtaining request 302 includes multimedia related information of the terminal device, where the multimedia related information includes model information and package name and version information of an application installed in the terminal device. The multimedia-related information is information associated with a multimedia file generated using a target application installed in the terminal device, and includes at least one of hardware information and software information of the terminal device. From the preset values 303 of the candidate multimedia parameters (for example, the values of the candidate multimedia parameters include an a frame rate 18, a resolution 576 × 1024, a B frame rate 20, and a resolution 720 × 1280), a value 304 of the multimedia parameter (for example, the B frame rate 20, the resolution 720 × 1280) matching the multimedia related information is determined. The determined value 304 is returned to the terminal device so that the terminal device generates a multimedia file based on the value of the multimedia parameter.
The method provided by the above embodiment of the present disclosure can determine the value of the multimedia parameter matched with the terminal device through the multimedia related information. The same numerical value is not uniformly issued to a plurality of terminal devices, so that the issued numerical value of the multimedia parameter 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 this embodiment, an execution subject of the information processing method (e.g., a server shown in fig. 1) may receive a multimedia parameter acquisition request sent by a terminal device. And the multimedia parameter acquisition request comprises the multimedia related information of the terminal equipment. Thus, the executing body can determine the value of the multimedia parameter matched with the multimedia related information. The multimedia-related information is various information related to multimedia.
In this embodiment, the execution subject may determine the value of the multimedia parameter matching the multimedia related information from preset values of candidate multimedia parameters. And, writing the value of each multimedia parameter into the value table value set. Here, the value table value set includes values of the respective multimedia parameters. The value set may be a value table, a value queue, or the like. The multimedia related information and the numerical value table numerical value set have a corresponding relation. For example, the multimedia related information may include chip information, and the values of the multimedia parameters in a value table value set may be only used for specified terminal devices, and the terminal devices are installed with chips produced by a certain manufacturer. In practice, whether the terminal device is the above-specified terminal device can be judged through the model information.
In some optional implementations of this embodiment, before step 402, the method further includes:
the default value of each multimedia parameter is written into the value set.
In these alternative implementations, the executing entity may write a default value into the value set before finding the value of the matching multimedia parameter. Therefore, if the value of the matched multimedia parameter is not found subsequently, a default value can be adopted to ensure that the terminal equipment can generate the multimedia file smoothly. The default value refers to a preset value, and the default value is usually strong in universality and can be used for most terminal devices.
In some optional application scenarios of these implementations, the step 402 may include:
in response to finding that one numerical combination of the multimedia parameters is matched with the received multimedia related information, replacing the default numerical value in the numerical set with the numerical value in one numerical combination, wherein the numerical combination of the multimedia parameters comprises the numerical value of each multimedia parameter;
in response to finding other matching numerical combinations than one numerical combination for the received multimedia related information, performing the following steps:
for each multimedia parameter in other numerical value combinations, determining whether the numerical value of the multimedia parameter in the numerical value combination of the multimedia parameter and the searched last multimedia parameter is the same; in response to determining that the values of the multimedia parameter are different, determining the value of the multimedia parameter after the creation time in other parameter combinations and the value combination of the previous multimedia parameter, and using the value of the multimedia parameter in the value set.
In these optional application scenarios, one multimedia parameter corresponds to one value, and then each multimedia parameter corresponds to a combination of values of the multimedia parameter. The executing body may traverse the value combination of each multimedia parameter to find a value combination matching the received multimedia-related information. The number of numerical combinations found here may be one or more. And if the numerical combination of the multimedia parameters matched with the received multimedia related information is found, replacing each default numerical value in the numerical value set by each numerical value in the found numerical combination. With the continuous change of the software information of the terminal device, such as system upgrade or software upgrade, the processing capability of the terminal device may be improved, for example, high-resolution video may be generated at high speed after the improvement. Accordingly, the values of the multimedia parameters used to generate the multimedia file may also change.
The executing agent may find one or more other numerical combinations for the received multimedia-related information. In the searching process, the value of the multimedia parameter after the creation time can be determined in various ways. For example, when all matching numerical combinations are found, the creation time of the multimedia parameter in each numerical combination may be compared, and the last numerical value of the multimedia parameter at the creation time may be determined. It is also possible that after each matching combination of values is found or after a certain time interval, if one or more matching combinations of values are found, the creation time of the last found multimedia parameter and the time of the last found multimedia parameter can be compared for each multimedia parameter in the respective multimedia parameters. If the creation time of the value of the multimedia parameter found last time is later, the value is reserved. And if the time for creating the searched value of the multimedia parameter is later, updating the value of the multimedia parameter in the value set by using the searched value of the multimedia parameter. For example, if the resolution of the last found numerical combination of the multimedia parameters is 576 × 1024, the creation time is 1 month, 1 day and 0 in 2000, the found resolution is 720 × 1280, and the creation time is 1 month, 2 days and 3 in 2000, the creation time of the resolution found this time is later, and the resolution in the data table is updated to 720 × 1280.
The values of the multimedia parameters obtained by the application scenarios are up-to-date, so that the executing body can obtain up-to-date values that are more matched with the multimedia related information of the terminal device with the change of the terminal device or other changes. The terminal equipment can generate the multimedia file more smoothly by using the numerical values, and the generated multimedia file has higher quality.
And step 403, returning the determined numerical value to the terminal equipment, so that the terminal equipment generates a multimedia file based on the numerical value of the multimedia parameter.
In this embodiment, the execution subject may return the determined value of the multimedia parameter to the terminal device, so that the terminal device generates the multimedia file based on the returned value. The multimedia file may include video and/or audio. In particular, the values of the multimedia parameters are the values of the parameters required for making video or audio. The value of the multimedia parameter issued by the execution main body 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 values of the parameter can be prevented.
In the embodiment, the numerical values of the multimedia parameters are presented in a table form so as to be updated subsequently, and finally the numerical values of the multimedia parameters most matched with the multimedia related information are obtained.
