[0015] In the following description, numerous details are set forth in order to provide a thorough understanding of the present disclosure; however, the present disclosure may be practiced in other ways than as described herein, and it is apparent that the embodiments in the specification are merely some, but not all, of the embodiments of the present disclosure.

[0016] SUMMARY OF THE DISCLOSURE The embodiments of the present disclosure provide a method, apparatus, device, and medium for secure multimedia editing file conversion.

[0017] 1 shows a flow diagram of a multimedia editing file conversion method provided by an embodiment of the present disclosure. As shown in FIG. 1, the multimedia editing file conversion method includes the following steps:

[0018] S110, obtaining a first multimedia editing file, the first multimedia editing file being used to indicate an editing project for performing an editing operation on the multimedia material, being used to indicate first instruction information of the multimedia material, and being used to indicate second instruction information of the editing operation to be encapsulated as the first multimedia editing file according to a first data format, the first data format being a data format supported by the first application.

[0019] The first multimedia editing file refers to the original editing file that was generated using the first application.

[0020] Optionally, the first multimedia editing file includes, but is not limited to, a video editing file, an audio editing file, a photo editing file, and a text editing file, and thus the first application includes, but is not limited to, a video editing application, an audio editing application, a photo editing application, and a text editing application.

[0021] The first multimedia editing file includes instruction information, the instruction information corresponds to a first data format, and the instruction information includes first instruction information and second instruction information, specifically, the first instruction information for indicating a multimedia material may be a material number, and the second instruction information for indicating an editing operation is a binary command.

[0022] The editing project refers to a video project, an audio project, a text project, etc. obtained by editing in a first application, and the editing project corresponds to a first data format, and the editing operation refers to a processing operation that generates the editing project, which includes at least one of a video editing operation, an audio editing operation, a text editing operation, and a special effects editing operation.

[0023] The multimedia material refers to the original material used when the first application generates the editing project.

[0024] An editing operation is a processing operation that generates an editing project based on multimedia material.

[0025] In this embodiment, the electronic device utilizes a first application to determine multimedia materials and editing operations on the multimedia materials according to a user's operation, each multimedia material is indicated by a first instruction information, and the editing operations on the multimedia materials are indicated by a second instruction information, and the first application generates a first multimedia editing file according to the first instruction information and the second instruction information. Further, the first application uses a preset editing assembly to identify the first instruction information and the second instruction information from the first multimedia editing file, obtain the multimedia materials according to the first instruction information, perform editing operations on the multimedia materials according to the second instruction information, and generate an editing project, and finally, the first application displays the generated editing project on an editing interface.

[0026] Take as an example that the first application is a first video editing application, and the first multimedia editing file is a first video editing file. After a user shoots a video, the user uses the first video editing application to cut the shot video, for example, the user adds special effects and background music to the video and adjusts the playback order in the video editing interface of the first video editing application, the added special effects, the added background music and the determined playback order are video materials, i.e., multimedia materials, the operations of adding special effects, adding background music and adjusting the playback order are video editing operations, i.e., editing operations, and finally, the first video editing file, i.e., the first multimedia editing file, is generated according to the first instruction information corresponding to the video materials and the second instruction information corresponding to the video editing operations. Further, the first video editing application uses the video editing assembly to identify the first instruction information and the second instruction information from the first video editing file, obtain the video materials according to the first instruction information, perform editing operations on the video materials according to the second instruction information, and generate a video project, and finally, the first video editing application displays the generated video project in the video editing interface.

[0027] It should be understood that since the first data format is a data format supported by the first application, it means that a file in the first data format can be read and processed by the first application, but this does not mean that the first application only supports the first data format and cannot support other data formats.

[0028] S120, the first multimedia editing file is analyzed to obtain first indication information and second indication information.

[0029] It should be understood that the electronic device uses a first application to generate an editing project, and displays the editing project in an editing interface, and then when a user wants to continue editing using the editing project, the electronic device shares the first multimedia editing file to a second application according to the user's sharing operation. Specifically, in the sharing process, the electronic device performs data format analysis on the first multimedia editing file through a data format analysis assembly preset in the first application or the device system, and obtains first instruction information and second instruction information.

[0030] S130, encapsulating the first instruction information and the second instruction information as a second multimedia editing file according to a second data format, the second multimedia editing file being used to indicate the editing project, and the second data format being a data format supported by a second application.

[0031] The second multimedia editing file refers to the target editing file generated after performing a data format conversion on the instruction information using the second application.

[0032] Optionally, the second multimedia editing file includes, but is not limited to, a video editing file, an audio editing file, a photo editing file, and a text editing file, and thus, the second application includes, but is not limited to, a video editing application, an audio editing application, a photo editing application, and a text editing application.

[0033] The second multimedia editing file includes instruction information, the instruction information corresponding to a second data format, and the instruction information includes first instruction information and second instruction information.

[0034] It should be understood that since the second data format is a data format supported by the second application, it means that a file in the second data format can be read and processed by the second application, but this does not mean that the second application only supports the second data format and cannot support other data formats.

[0035] In some embodiments, the second data format may be a common data format that can be supported by both the first application and the second application, that is, the second multimedia editing file is an intermediate file that can be read by both the first application and the second application. Specifically, after using the first application to generate the first multimedia editing file and sharing the generated video project to the second application, the first application encapsulates the first instruction information and the second instruction information obtained by parsing into the first multimedia editing file according to the second data format as the second multimedia editing file. Furthermore, the second application uses the preset editing assembly to identify the first instruction information and the second instruction information from the second multimedia editing file, and determines an editing project based on the first instruction information and the second instruction information; finally, the second application can directly display and post the editing project in the editing interface, and can also generate a new editing project based on the user's operation on the editing project; finally, the second application can display and post the new editing project in the editing interface.

[0036] Take as an example that the first application is a first video editing application, the first multimedia editing file is a first video editing file, and the second application is a second video editing application. After using the first video editing application to generate the first video editing file and sharing the generated video project to the second video editing application, the first video editing application encapsulates the first instruction information and the second instruction information obtained by parsing into the first video editing file according to the second data format as a second video editing file. Furthermore, the second video editing application uses a preset video editing assembly to identify the first instruction information and the second instruction information from the second multimedia editing file, and determines a video project according to the first instruction information and the second instruction information; finally, the second video editing application can directly display and post the video project in the video interface, and can also generate a new video project according to the user's operation on the video project; finally, the second video editing application can display and post the new video project in the editing interface.

[0037] In some other embodiments, the second data format is a data format supported by the second application and not supported by the first application, that is, the second multimedia editing file is a file that can only be read by the second application. Specifically, after using the first application to generate the first multimedia editing file and sharing the generated video project to the second application, the device system or other application can encapsulate the first instruction information and the second instruction information obtained by parsing into the first multimedia editing file as the second multimedia editing file according to the second data format. Furthermore, the second application can use the preset editing assembly to identify the first instruction information and the second instruction information from the second multimedia editing file, and determine an editing project based on the first instruction information and the second instruction information; finally, the second application can directly display and post the editing project in the editing interface, and can also generate a new editing project based on the user's operation on the editing project; finally, the second application can display and post the new editing project in the editing interface.

[0038] An embodiment of the present disclosure provides a method for converting a multimedia editing file, including first obtaining a first multimedia editing file, the first multimedia editing file being used to indicate an editing project for performing an editing operation on multimedia material, and used to indicate first instruction information of the multimedia material, and second instruction information of the editing operation to be encapsulated as the first multimedia editing file according to a first data format, the first data format being a data format supported by a first application; then analyzing the first multimedia editing file to obtain the first instruction information and second instruction information, and then encapsulating the first instruction information and the second instruction information as a second multimedia editing file according to the second data format, the second multimedia editing file being used to indicate the editing project, the second data format being a data format supported by a second application. With the above method, the multimedia editing materials and editing operations of a multimedia editing file are indicated by different instruction information, and the instruction information is encapsulated as a data format that can be supported by each application program itself, eliminating the need to convert and edit large amounts of multimedia materials. By converting the instruction information, file format conversion in different applications is realized. This conversion method is easy to implement and has high conversion efficiency, and also supports the conversion of multimedia editing files that occupy a large amount of internal storage space in different application programs, improving the reliability and versatility of multimedia file conversion.

[0039] In another embodiment of the present disclosure, the methods of acquiring multimedia material are diverse, and the types of multimedia material are also diverse.

[0040] Specifically, the method of acquiring multimedia materials is as follows: Obtaining multimedia material from a multimedia editing interface of the first application; calling a port of a material parsing assembly of the first application to obtain multimedia material; The method includes at least one of: invoking a port of a special effects assembly of the first application to obtain the multimedia material.

[0041] The multimedia editing interface provides original multimedia editing data, including text data, audio data, video data, and so on.

[0042] The ports of the material analysis assembly can acquire material analysis data, and the ports of the material analysis assembly can acquire data such as variable speed data, rotation data, zoom data, and the like.

[0043] The ports of the special effects assembly can obtain special effects data, which may include audio special effects, video special effects, and the like.

[0044] Optionally, the multimedia material comprises: The data includes at least one of canvas data, video material data, audio material data, photo material data, and text material data, or a combination of multiple data.

[0045] Optionally, the canvas data includes a canvas size, the video material data includes at least one of a video duration, a video cutting time, a video variable speed data, a video rotation data, a video zoom data, a video width and height, an original path, a relative canvas position, a track level, the audio material includes at least one of an audio duration, an audio cutting time, an audio variable speed data, a volume data, an audio rotation data, an audio zoom data, an audio width and height, an audio track level, the photo material data includes at least one of a photo size, a relative canvas position, a photo color, a scenery in the photo, and the text material data includes at least one of a text size, a relative canvas position, a track level.

[0046] Therefore, different types of multimedia materials can be obtained through multiple ports, so that the multimedia editing file conversion method can use various scenarios such as video conversion, audio conversion, text conversion, photo conversion, etc., and the versatility of the method is improved.

[0047] In another embodiment of the present disclosure, the second data format may be a common data format that may be supported by both the first application and the second application, and a data format conversion is performed by the protocol assembly, and the second data format may be a format that is supported by the second application and not supported by the first application.

[0048] In some embodiments of the present disclosure, the second data format may be a common data format that can be supported by both the first application and the second application, and thus, after S130, the method includes the following steps:

[0049] The second multimedia editing file is encapsulated as a third multimedia editing file in response to a third data format, the third multimedia editing file being used to represent the editing project, the third data format being a data format supported by the second application and not supported by the first application.

[0050] Specifically, the editing operation indicated by the second instruction information in the first multimedia editing file is realized through a first protocol assembly, and the first protocol assembly supports a first data format but does not support a second data format and a third data format;

[0051] The editing operation indicated by the second instruction information in the third multimedia editing file is realized via a second protocol assembly, which supports the third data format but does not support the first data format and the second data format.

[0052] The first protocol assembly and the protocol relay assembly are predefined in a first application, and the second protocol assembly is predefined in a second application.

[0053] The format conversion process between the two applications is described in detail as follows: first, the first application uses the first protocol assembly to generate a first multimedia editing file according to the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation in accordance with the first data format; then, the first application uses the relay protocol assembly to analyze the first multimedia editing file to obtain the first instruction information and the second instruction information; then, the first application uses the relay protocol assembly to generate a second multimedia editing file according to the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation in accordance with the second data format; because the second data format is a common data format that can be supported by both the first and second applications, the first multimedia editing file that is not supported by the second application is converted into a second multimedia editing file that is supported by the second application; finally, the second application uses the second protocol assembly to generate a third multimedia editing file according to the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation in accordance with the third data format.

[0054] To avoid generating redundant files in the photo album or audio folder, the second multimedia editing file can be stored in the internal storage of the first application, and the second application retrieves the second multimedia editing file from the internal storage of the first application.

[0055] Thus, in some embodiments, prior to encapsulating the second multimedia editing file into a third multimedia editing file in accordance with the third data format, the method further comprises: storing the second multimedia editing file in the internal storage device of the first application, and setting the access authority of the storage path of the second multimedia editing file; and in response to a sharing operation for the second application, granting access authority to the storage path to the second application.

[0056] The internal storage device of the first application refers to a local internal storage device or a cloud space corresponding to the first application.

[0057] The access permission setting refers to opening or closing the access permission to the storage path of the second multimedia editing file.

[0058] The share operation is a user operation for triggering a first application to share a second multimedia editing file to a second application.

[0059] Furthermore, after opening the access authority, encapsulating the second multimedia editing file into a third multimedia editing file according to a third data format, specifically including the following steps:

[0060] When receiving an access request to the storage path sent by the second application and invoking a file sharing assembly and a file access assembly preset for the second multimedia editing file, the second multimedia editing file is read from the internal storage device of the first application, and the second multimedia editing file is encapsulated as a third multimedia editing file according to a third data format.

[0061] The access request is request information for accessing the storage path of the first application.

[0062] The file sharing assembly may be a shared port between the first application and the second application. Specifically, the file sharing assembly may be a FileProvider provided by a device system of a device on which the first application is deployed and deployed in a drive layer of the device system.

[0063] The file access assembly refers to an access port between the first application and the second application. Specifically, the file access assembly may be a ContentProvider provided by a device system of a device on which the first application is deployed and disposed in a drive layer of the device system.

[0064] It should be understood that when calling the equipment system to launch the second application, the equipment system first determines whether the second application is installed, if the second application is installed, launches the second application directly, the second application generates an access request to the storage path, and the first application sends the second multimedia editing file to the second application in response to the access request. Under other circumstances, if the second application is not installed, after the equipment system installs and launches the second application, the second application generates an access request to the storage path, and the first application sends the second multimedia editing file to the second application in response to the access request.

[0065] To understand the interaction logic between the first application and the second application, refer to FIG. 2, when the second application triggers to query the storage path, it calls the file access assembly (ContentProvider) to send an access request for the storage path, and then the first application calls the file sharing assembly (FileProvider) to send the second multimedia editing file to the second application.

[0066] The above file conversion process is described below based on the basic architecture. FIG. 3 shows a schematic diagram of the basic architecture of the electronic device provided by the embodiment of the present disclosure.

[0067] As shown in Figure 3, the basic architecture includes an application layer, a protocol layer, and a driving layer. The application layer includes a first application and a second application. The protocol layer includes a first protocol, a relay protocol, and a second protocol. The driving layer includes a port of a video analysis assembly (abbreviated as Video Analysis SDK), a port of a special effect assembly (abbreviated as Special Effect SDK), a file sharing assembly (FileProvider), and a file access assembly (ContentProvider).

[0068] Specifically, the first protocol corresponds to a first protocol assembly, and the first application uses the first protocol assembly to generate a first multimedia editing file according to the first data format based on the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation. Optionally, the multimedia material can obtain video material data through a video analysis SDK and obtain special effect material data through a special effect SDK. Further, the relay protocol corresponds to a relay protocol assembly, and the first application uses the relay protocol assembly to generate a second multimedia editing file according to the second data format based on the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation. Further, the second protocol corresponds to a second protocol assembly, and the second application uses the second protocol assembly to generate a third multimedia editing file according to the third data format based on the first instruction information corresponding to the multimedia material and the second instruction information corresponding to the editing operation.

[0069] Therefore, the second multimedia editing file corresponding to the second data format is used as a relay file between the first application and the second application, thereby realizing data format conversion between the applications.

[0070] In some other embodiments of the present disclosure, the editing operation indicated by the second instruction information in the first multimedia editing file is realized by a first application, which supports a first data format but does not support a second data format, and the editing operation indicated by the second instruction information in the second multimedia editing file is realized by a second application, which supports the second data format but does not support the first data format, and thus S130 specifically includes the following steps:

[0071] The first instruction information and the second instruction information are encapsulated as a second multimedia editing file according to a second data format using a pre-configured relay application.

[0072] The relay application is an application installed in a device system other than the first application and the second application. Specifically, the relay application stores in advance a correspondence relationship between the first data format and the second data format, and converts the first data format into the second data format based on the correspondence relationship to generate a second multimedia editing file supported by the second application.

[0073] Therefore, the relay application can be used as a bridge for data format conversion to achieve data format conversion between applications.

[0074] In a further embodiment of the present disclosure, a whole method for converting multimedia editing files is described. For illustration, the embodiment uses the above embodiment of the protocol assembly as a specific implementation method for implementing data format conversion.

[0077] S430, encapsulating the first instruction information and the second instruction information as a second multimedia editing file according to a second data format, the second multimedia editing file being used to represent the editing project, and the second data format being a data format supported by a second application.

[0079] S450, in response to a sharing operation for the second application, granting the second application access authority to the storage path.

[0080] S460, calling a second application.

[0081] S470, determining whether a second application is installed.

[0082] Specifically, if the second application is installed, execute S480 directly; otherwise, execute S490.

[0083] S480, directly launching the second application to receive the access request for the storage path sent by the second application, and simultaneously invoking a file sharing assembly and a file access assembly preset for the second multimedia editing file.
