[0042] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0043] First, the terms involved in one or more embodiments of the present application are explained.

[0044] KMP (Kotlin Multiplatform): A cross-platform development framework based on the Kotlin language, which allows you to run on Android, iOS, Web, and Harmony by developing the same set of code.

[0045] BSDifff: A binary difference tool that can perform incremental updates of files by comparing new and old files.

[0046] Figure 1 A flowchart of a video draft access method according to an embodiment of the present application is shown. Figure 1 As shown, the method comprises the following steps:

[0047] Step S101, the first platform edits the video draft, stores the video draft according to a preset draft protocol, and obtains a corresponding data packet.

[0048] The first platform may be an Android platform, an IOS platform, a Hongmeng platform, a web platform, or other platforms, and a video draft is obtained by editing the video using an editing engine on the first platform. The editing engine may be any video editing APP, which is not limited here.

[0049] Based on the editing engine of the first platform, users can edit videos, such as material selection, position setting, playback speed setting, adding special effects, adding subtitles, adding filters, adding stickers, adding background music, setting transitions, setting picture-in-picture, etc. During the editing process, for the storage of video drafts, in order to facilitate seamless synchronization of video drafts on different platforms and platforms of different devices, this embodiment stores video drafts based on a preset draft protocol, ensuring that different platforms or platforms of different devices can store data packets suitable for each platform based on the same preset draft protocol.

[0050] The preset draft protocol can include multiple protocols, such as engine layer protocol, business layer protocol and platform layer protocol. The engine layer protocol predefines the video data structure, which includes the core data of the video draft. The video data structure includes various data such as the engine's timeline, video track, audio track, subtitle track, sticker track, filter track, transition, picture-in-picture, etc., and records various video-related information in the video draft.

[0051] The business layer protocol predefines the business processing data structure, which is set according to specific business needs. For example, the business processing data structure includes business sources, business processing types, etc. Business processing types include video production, AI-generated stories, shooting, and publishing. Video production can convert videos into films through templates, and the corresponding parameter information of the template needs to be recorded; AI-generated stories can generate video stories based on AI and other technologies, and record the corresponding timeline information; shooting, publishing, etc. determine the corresponding information to be recorded according to business needs. The above is an example, which is set according to the implementation situation. The business layer protocol can set the data structure required for different business processing according to business needs, which is not limited here.

[0052] The platform layer protocol predefines data structures including platform type, engine type, engine version, draft version, etc., which are used for video draft restoration. Data alignment, data type conversion and other processing are performed for different platform types, engine types, engine versions, draft versions, etc. to ensure accurate restoration of the video draft.

[0053] When the first platform edits the video draft, for example, taking the first platform as an Android platform, the video draft is edited based on the editing engine of the Android platform, and when the video draft is stored, it is stored according to the preset draft protocol to obtain a corresponding data packet. Among them, each data in the video data structure included in the data packet is stored in the data type of the video draft of the Android platform, the business processing data structure is stored based on business needs, the platform type is the Android platform, the engine type is the type of video editing engine used by the Android platform, the engine version is the version of the video editing engine used by the Android platform, and the draft version is the version information of the stored video draft.

[0054] The default draft protocol is as follows Figure 2 As shown, the preset draft protocol includes the engine layer protocol TimeLineInfo, the business layer protocol BizInfo and the platform layer protocol PlatFormInfo. The engine layer protocol includes caption type CaptionTrackInfo, audio type AudioTrackInfo, sticker type StickerTrackInfo, video type VideoTrackInfo, etc., corresponding to the relevant information of the video; the business layer protocol includes bizFrom type int, capture type CaptureBizInfo, aistory type AiStoryBizInfo, etc., corresponding to the business source and business processing type, etc.; the platform layer protocol includes platform type int, enginetype type String, engineVer type String, draftVer type String, etc. The above is an example, and each type is set according to the implementation situation, which is not limited here. Taking the engine layer protocol of the video draft as V1, the business layer protocol as B1, and the platform layer protocol as P1 as an example, the final data packet is {V1, B1, P1}, including the above data. In the above example, only a few protocols are listed, but in actual application, more protocols can be set for selection according to the implementation situation. In addition, the specific content of each protocol also needs to be set according to the implementation situation.

[0055] Step S102, uploading the data packet to cloud storage.

[0056] The first platform uploads the data table stored according to the preset draft protocol to the cloud storage, so that the data packet can be directly obtained from the cloud without being restricted by the device or platform and continue to be edited and processed, etc., to facilitate data synchronization.

[0057] Further cloud storage can also avoid problems such as local storage loss and ensure the security of data packets.

[0058] Step S103, the second platform obtains the data packet stored in the cloud, parses the data packet according to a preset draft protocol based on the cross-platform development framework, and obtains a video draft suitable for the second platform, so as to restore and display the video draft on the second platform.

[0059] The second platform can directly obtain the stored data packets from the cloud to achieve seamless synchronization and sharing of data packets. The second platform can restore the video draft based on the obtained data packets, and continue to perform editing and other operations based on the restored video draft, making it convenient to edit the video draft without being restricted by the platform, equipment, etc.

[0060] The second platform can be a platform of a different platform type from the first platform, such as the first platform is an Android platform, and the second platform can be an IOS platform, etc. For the second platform of a different platform type from the first platform, when it obtains a data packet, considering the differences in data types between different platforms, a cross-platform development framework, such as KMP, can be used to realize the cross-platform universality of the data packet based on the kotlin language. Specifically, KMP converts the data type applicable to the first platform for editing the video draft into a data type applicable to the second platform. For example, after the Android platform edits the video draft, the data type stored in the data packet is the data type of the Android platform. When the IOS platform restores the video draft, KMP performs data type conversion on the data in the data packet, and converts the data in the data packet into a data type applicable to the IOS platform, so that the editing engine of the IOS platform can directly read the data packet and restore and display the video draft. When KMP converts the data type of the data in the data packet, the mapping relationship of the data type can be pre-set. According to the mapping relationship, KMP automatically converts the data in the data packet for type conversion, so that the IOS platform can seamlessly and synchronously obtain the data packet of the video draft of the Android platform, and restore and display the video draft. When converting data types, KMP determines each data in the data packet according to the preset draft protocol, and can also determine the platform type of the first platform storing the data packet through the platform layer protocol, and determine that the platform types of the two platforms are different according to the platform type of the second platform that obtains the data packet, and convert the data type of the data in the data packet according to the data type mapping relationship. Further, the preset draft protocol is built based on cross-platform, and the data packet contains the data required by each platform. The data required by different platforms may be different. For example, when the first platform stores the video draft, it involves field 1 and field 3, and the values ​​of field 1 and field 3 are stored in the data packet, but field 2 is not involved, so the value of field 2 is set to null. When the second platform restores the video draft, field 2 is involved, and field 1 and field 3 are not involved. It may also be necessary to align field 2 according to field 1 and field 3. The mapping relationship between fields can be pre-set, and KMP automatically aligns the value of field 2 in the data packet according to the mapping relationship, so that the obtained data packet is a data packet suitable for the second platform. The second platform can parse and restore the data packet to obtain the video draft for display, and continue to perform editing and other processing. The above is an example, which is specifically set according to the implementation situation and is not limited here.

[0061] According to the video draft storage and access method provided by this application, the video draft is stored according to a preset draft protocol. The cross-platform development framework can parse the data packets storing the video draft into video drafts suitable for different platforms, thereby achieving seamless synchronization and sharing of draft data between different platforms, reducing the maintenance cost of video drafts, and facilitating users to easily process video drafts.

[0062] Figure 3A flowchart of a video draft access method according to an embodiment of the present application is shown. Figure 3 As shown, the method comprises the following steps:

[0063] Step S301, the first platform edits the video draft, stores the video draft according to a preset draft protocol, and obtains a corresponding data packet.

[0064] The preset draft protocol sets up storage for video drafts based on a cross-platform basis, so that different platforms can store data packets with the same data structure based on the preset draft protocol, so that data packets can be seamlessly synchronized and shared between different platforms. Users can edit video drafts without being restricted by devices, platforms, etc., making it more convenient and quicker.

[0065] Specifically, the first platform can edit the video draft by selecting video material to enter the editing engine of the first platform, or enter the editing engine of the first platform in an intelligent filming mode to edit the video draft, etc. In the editing engine of the first platform, users can perform various editing processes such as timeline adjustment, subtitle addition, BGM addition, special effects addition, picture-in-picture addition, and transition setting on the video draft, and the video draft will present the corresponding display effect. When storing the video draft, various video-related data of the video draft need to be stored accordingly to obtain a data packet. The data packet includes a video data structure predefined according to the engine layer protocol of the preset draft protocol. The video data structure includes various video-related data, such as timeline, video track, audio track, subtitle track, sticker track, filter track, transition, picture-in-picture, etc. According to the video-related data recorded in the video data structure, the video elements contained in the video draft can be accurately determined. This embodiment obtains the corresponding data in the video draft according to the engine layer protocol in the preset draft protocol, and stores each data according to the video data structure corresponding to the engine layer protocol.

[0066] Furthermore, different business requirements require different processing of video drafts. Therefore, the data packet also includes the business processing data structure predefined by the business layer protocol. The business processing data structure includes the business source, business processing type, etc., which facilitates users to continue editing and processing the video draft based on the business-related data contained in the business processing data structure. According to the business layer protocol, according to the business processing method of the video draft, the corresponding data such as the business source and business processing type are stored.

[0067] Further, in addition to the data structures predefined by the above engine layer protocol and business layer protocol, in order to facilitate cross-platform editing and processing of video drafts, this embodiment also includes a platform layer protocol in the preset draft protocol. Based on the platform layer protocol, when parsing the data packet, the first platform used to store the data packet can be determined based on the platform type of the platform layer protocol, and then the data in the data packet is processed by cross-platform data type conversion, data alignment, etc. to obtain a data packet suitable for the second platform. In addition to the platform type, the platform layer protocol also includes data such as engine type, engine version, and draft version. When different platforms use different engine types or different engine versions, corresponding data conversion, alignment, etc. are also required according to the specific engine type and engine version. The draft version records the version when the video draft is stored. Different draft versions will also affect the different data stored in the data packet. When the second platform reads data packets of different draft versions, there may be a situation where the draft versions are different and cannot be restored normally. It is necessary to re-select the data packet of the applicable draft version, or, because the data affects the parsing, it is necessary to perform different data alignments according to the different draft versions to ensure normal video restoration. The platform type is determined according to the first platform, the engine type and engine version are determined according to the editing engine used by the first platform, the draft version is determined according to the engine type and engine version, etc., or it can also be determined according to the preset draft protocol version, etc. The preset draft protocol can be updated according to business needs to obtain different versions of preset draft protocols. The cross-platform development framework can set mapping relationships and data alignment processing for data packets of different versions of preset draft protocols to ensure the correct parsing of data packets. The above is an example, which is set according to the implementation situation and is not limited here.

[0068] Step S302, saving the data packet to local storage for the first platform to read the data packet.

[0069] After the first platform edits the video draft, it obtains a data packet according to the preset draft protocol. After obtaining the data packet, it can first save the data packet to local storage, so that the editing engine of the first platform can read the data packet and continue to edit the video draft.

[0070] Step S303: upload the data packet to the cloud server for storage.

[0071] To facilitate cross-platform synchronization and sharing of data packets, data packets can be uploaded to the cloud server for storage. Cloud server storage of data packets can ensure the security of data packets and avoid problems such as local data packets being lost and unable to be retrieved. Cloud servers store data packets, which facilitates data packet sharing. The second platform can directly obtain data packets from the cloud server to achieve data packet synchronization and sharing.

[0072] Furthermore, when the same video draft is edited using multiple different devices, multiple devices edit the video draft, and multiple different data packets will be obtained when storing, which is prone to data conflict problems in the data packets. For example, if device 1 edits the video draft and adds filter 1, and device 2 edits the video draft and adds filter 2, etc., if multiple different data packets are directly uploaded to the cloud server, data conflicts in the data packets will occur. Considering the above problems, before uploading the data packets to the cloud server, conflict detection is performed on multiple data packets to determine the part of the data with data conflicts. According to the data conflicts, the required target conflict data packets can be determined by screening, and finally the target conflict data packets are uploaded to the cloud storage. Alternatively, before uploading the data packets, conflict detection is performed on the data packets to be uploaded and the data packets stored in the cloud server. For example, the data packets stored in the cloud server use audio 1, and the data packets to be uploaded use audio 2. Through conflict detection, it can be determined that there are some data with data conflicts, such as audio conflicts. If the data conflict here is an erroneous modification, the editing error problem can be detected through the data conflict and the correct data packet can be determined.

[0073] When filtering target conflicting data packets, it can be determined by preset filtering rules, or a selection interface can be provided to facilitate users to specify target conflicting data packets, which is not limited here.

[0074] Furthermore, during uploading, a conflict detection method can be used to detect the different data parts between the data packet and the cloud server. The target conflicting data packet can only be the different data parts, thereby reducing the bandwidth occupied by uploading.

[0075] Step S304: The second platform obtains the data packet stored in the cloud based on incremental synchronization and / or full synchronization.

[0076] When the second platform obtains data packets from the cloud, it can provide the second platform with incremental synchronization or full synchronization and other acquisition methods, taking into account the traffic conditions and costs of network transmission. In the case of full synchronization, all data packets stored in the cloud are provided to the second platform, and the second platform obtains the entire data packet stored in the cloud. In the case of incremental synchronization, only the difference between the data packets stored in the second platform and the existing data packets can be synchronized. For example, the bytecode difference between the data packets stored in the cloud server and the data packets already in the second platform can be compared. The cloud server can generate a difference data packet containing only the difference. The second platform obtains the difference data packet and combines the existing data packet with the difference data packet to obtain the data packet stored in the cloud. Compared with directly obtaining the data packet, the transmission time required for acquisition, the traffic consumed, etc. are reduced, thereby improving the acquisition efficiency. The above incremental synchronization method can adopt an incremental update method such as BSDifff, which is not limited here.

[0077] Step S305, based on the KMP cross-platform development framework, perform data type conversion and / or data alignment processing on the data packet according to the preset draft protocol, so that the processed data packet is suitable for the second platform, and the video draft is restored and displayed on the second platform.

[0078] After the second platform obtains the data packet, it can parse the data table through the KMP cross-platform development framework according to the platform layer protocol of the preset draft protocol based on the platform type, engine type, engine version, draft version, etc. of the second platform and the first platform to obtain a data packet suitable for the second platform, so as to facilitate the second platform to seamlessly synchronize the data packet and restore the video draft for display, editing and other processing.

[0079] When the platform types of the second platform are different from those of the first platform, when the second platform obtains a data packet, the KMP cross-platform development framework can perform data type conversion and data alignment processing on the data of the data packet according to the platform type of the second platform and the platform type of the first platform in the data packet. The conversion and data alignment processing can be processed according to a preset mapping relationship and automatically completed by the KMP cross-platform development framework to perform data type conversion or data alignment according to the data in the data packet. Refer to the description of step S103, which is not elaborated here.

[0080] Alternatively, the second platform has the same platform type as the first platform, but uses different engines, that is, the second platform and the first platform use different editing engines to edit video drafts. The KMP cross-platform development framework can perform data type conversion and data alignment on the data packet according to the engine type of the second platform and the engine type of the first platform in the data packet to obtain a data packet suitable for the second platform.

[0081] Alternatively, the second platform and the first platform have the same platform type but different engine versions, that is, the second platform and the first platform use different versions of the same editing engine to edit the video draft. The KMP cross-platform development framework can perform data type conversion and data alignment on the data packet according to the engine version of the second platform and the engine version of the first platform in the data packet to obtain a data packet suitable for the second platform.

[0082] Alternatively, the second platform and the first platform have the same platform type, engine type, and engine version, but the second platform is the second platform of device 2, and the first platform is the first platform of device 1, that is, the user uses different devices to edit the video draft. At this time, after obtaining the data packet, the second platform can determine according to the platform layer protocol that the platform type, engine type, and engine version of the second platform and the first platform are the same, and then it can directly parse the data packet and restore the video draft.

[0083] Furthermore, for the draft version in the platform layer protocol, when the draft version in the data packet is not compatible with the engine of the second platform, that is, the data obtained by parsing the data packet cannot be directly read by the editing engine of the second platform to restore the video draft, the KMP cross-platform development framework performs data type conversion and data alignment processing on the data packet according to the engine type and engine version of the editing engine of the second platform to obtain a data packet suitable for the editing engine of the second platform.

[0084] The above is an example for explanation. The specific settings will be based on the implementation situation and are not limited here.

[0085] According to the video draft storage and access method provided by the present application, based on the preset draft protocol, the data stored in the data packet is unified, so that different platforms can store the video draft data according to the preset draft protocol. When reading, the cross-platform development framework can parse the data packet stored in the video draft according to the platform layer protocol, according to the difference between the first platform and the second platform, into the video draft data suitable for the second platform, so as to realize data packet sharing. By using the cloud to store data packets, the limitations of devices, platforms, etc. on data packet storage are reduced, and it is convenient for different platforms to directly synchronize data packets. Furthermore, when uploading data packets, conflict detection is performed to avoid data packet data conflicts when multiple devices are editing the same video draft at the same time. When obtaining data packets from the cloud, an incremental synchronization method can be used to reduce network transmission and storage overhead, etc.
