When the service data is written in the media resource file by the sending end 120, the preset data is also written in the media resource file, where the preset data may specifically be data formed by a specific character string, and after the service data and the preset data are written in the media resource file, the preset data has a position-limited relationship with the service data in the media resource file in which the service data and the preset data are written, that is, the file data of the media resource file includes the service data and the preset data, and the preset data is used as known data, and the position of the preset data (i.e., the position of the preset data in the file data) is used for limiting the position of the service data.
Step S202, determining preset data for performing data matching in the media resource file.
In this step, the receiving end 110 may determine preset data for performing data matching in the media resource file after receiving the media resource file containing the service data from the sending end 120. As mentioned above, the preset data is known, and specifically may be data composed of a specific character string, in practical applications, the receiving end 110 may perform information interaction with the sending end 120 in advance, and the sending end 120 may agree with the receiving end 110 with the preset data for performing data matching on the media resource file sent from the sending end 120, so that the receiving end 110 may obtain the preset data that is agreed in advance for performing data matching in the media resource file after receiving the media resource file.
Step S203, performing data matching in the file data of the media resource file according to the preset data, and determining the target data limited by the position of the preset data in the file data.
And step S204, obtaining service data according to the target data.
In the above steps S203 and S204, after the receiving end 110 obtains the media resource file and the preset data, the receiving end 110 performs data matching in the file data of the media resource file according to the preset data, that is, retrieves the position of the preset data in the file data, if the preset data is composed of a specific character string, in step S203, the receiving end 110 searches the file data of the media resource file for the position of the specific character string, and after obtaining the position of the preset data in the file data, the receiving end can determine the target data defined by the position of the preset data accordingly, and then in step S204, the receiving end 110 can use the target data as the service data to complete the process of parsing the service data from the media resource file.
The method of the embodiment can quickly and accurately extract the service data from the file data of the media resource file based on a data matching mode, so that the dependence of a receiving end on an ffmpeg frame can be removed, the increase of a volume packet is effectively avoided, developers do not need to be skilled in mastering the packaging format of the media resource file, the use complexity is reduced, and the use cost is greatly reduced.
In some of these embodiments, the preset data may include preset header data and preset trailer data; the performing data matching in the file data of the media resource file according to the preset data in step S203 to determine the target data defined by the position of the preset data in the file data may include:

In this embodiment, the preset data may include preset header data and preset trailer data, specifically, when the sending end 120 writes the service data and the preset data into the media resource file, the preset data is respectively added to the head and the tail of the service data, the preset data added to the head of the service data is referred to as preset header data, the preset data added to the tail of the service data is referred to as preset trailer data, both the preset header data and the preset trailer data may be composed of specific character strings, the two preset data may be different to improve the retrieval efficiency, for example, the preset header data may be "export mp4 [", the preset trailer data may be "] ] export mp4", the preset service data is represented as data, and the sending end 120 writes the "export mp4[ [ data ] ] export mp4" into the media resource file. Therefore, after obtaining the media resource file and determining the preset header data and the preset trailer data, the receiving end 110 may first perform data matching in the file data of the media resource file according to the preset header data, so as to obtain data, called as the next file data, in the file data of the media resource file beginning after the position of the preset header data, and then perform data matching in the next file data according to the preset trailer data, so as to obtain data, which is the target data, of the next file data ending before the position of the preset trailer data. According to the scheme of this embodiment, the service data can be quickly and accurately extracted and obtained based on the data matching between the preset header data and the preset trailer data that are set at the head and the tail of the service data at the sending end 120.
In some other embodiments, the preset data may include preset header data and preset trailer data; the performing data matching in the file data of the media resource file according to the preset data in step S203 to determine the target data defined by the position where the preset data is located in the file data may include:

In this embodiment, the preset data includes preset header data and preset trailer data, when the sender 120 writes the service data and the preset data into the media resource file, the preset header data is added to the header of the service data, and the preset trailer data is added to the trailer of the service data, so as to write the expropump 4[ [ data ] ] expropump 4 "into the media resource file. Corresponding to the above embodiment, after obtaining the media resource file and determining the preset header data and the preset trailer data, the receiving end 110 may first perform data matching in the file data of the media resource file according to the preset trailer data, so as to obtain data where the file data of the media resource file is suspended before the position of the preset trailer data, where the data is called front-segment file data, and then perform data matching in the front-segment file data according to the preset header data, so as to obtain data beginning after the position of the preset header data in the front-segment file data, where the data is the target data. In the solution of this embodiment, data matching based on the preset header data and the preset trailer data that are set at the head and the tail of the service data at the sending end 120 may also be implemented, so as to quickly and accurately extract and obtain the service data.
As an application example of the method of the present application, referring to fig. 3, the sending end 120 may still use ffmpeg to encapsulate the media resource, when encapsulating the media resource, the sending end 120 may write the service data into a Metadata section of the MP4 file, and then when writing the service data, add preset header data "export MP4[ [" and preset tail data "] ] export MP4", and by adding the preset header data and the preset tail data, write the "export MP4[ [ data ] ] export MP4" into the MP4 file, and then send the MP4 file to the receiving end 110. Therefore, when the receiving end 110 receives the MP4 file, the data of the MP4 file can be directly read, and the service data can be analyzed in a data matching manner, so that the dependence of the receiving end 110 on the ffmpeg frame can be eliminated, developers do not need to master the packaging format of media resource files such as the MP4 file, the use complexity is reduced, and the use cost is reduced. Specifically, after receiving the MP4 file, the receiving end 110 may load the MP4 file into the memory, read the file data, may first traverse to obtain preset header data "export MP4 [", obtain the back-end file data starting after the position of the preset header data when the preset header data is matched, then traverse to obtain preset tail data "]exportmp 4" based on the back-end file data, and obtain the target data of the back-end file data ending before the position of the preset tail data when the preset tail data is matched, where the target data is the service data inserted into the Metadata section by the sending end 120, and after the service data is analyzed, the service layer may use the service data.

Illustratively, the service data may be related data such as a mask position of a video frame, the preset data may specifically be data formed by a specific character string, the sending end 120 may perform information interaction with the receiving end 110 in advance, and the sending end 120 may agree with the receiving end 110 with the preset data, so that the receiving end 110 is used for performing data matching on a media resource file sent from the sending end 120.
And step S402, obtaining a data combination to be written according to the service data and the preset data.
In this step, the sending end 120 obtains a data combination to be written according to the service data and the preset data, where the data combination includes the service data and the preset data, and may be composed of the service data and the preset data, and the preset data is used for performing position limitation on the service data in the data combination. As an example, the preset data may include preset header data and preset trailer data, and step S402 may include: and adding preset head data at the head of the business data and preset tail data at the tail of the business data to obtain a data combination to be written. Specifically, the sending end 120 may add preset header data "exportmp4 [" at the head of the service data, and then add preset tail data "] ] exportmp4" at the tail of the service data, so as to obtain a data combination to be written as "exportmp4[ [ data ] ] exportmp4", thereby facilitating the receiving end 110 to quickly and accurately parse the service data from the media resource file based on data matching.
