Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0044] First, the noun terms related to one or more embodiments of the present application are explained.

[0045] Clip draft data: refers to a collection of temporary data generated during video editing, including but not limited to video clips, subtitle text, sticker elements, filter effects, transition animations, and background music, etc. Users can modify and edit the clip draft data according to their needs to further adjust and improve the video effect.

[0046] Decentralization: In this application, it means that each business module or node in the video editing solution does not rely on a central service or a single control point, but communicates and collaborates through protocols to achieve data sharing and update. The communication here not only supports local communication but also remote communication control.

[0047] Distributed: In this application, it refers to geographical distribution, supporting multiple devices to collaborate on editing the same clip draft data and synchronizing the clip data to other services that listen for clip events remotely through protocols.

[0048] Real-time editing: It means that users can instantaneously see the editing effect during video editing, and the editing operations can be instantaneously synchronized to the nodes of other participating users without waiting for processing or upload to complete.

[0049] Clip protocol: In this application, it refers to the rules or standards used to define how each business module or node communicates, shares data, and collaborates.

[0050] CRDT (Conflict-free Replicated Data Type): It is a data structure used to achieve data consistency in a distributed system. It allows concurrent updates in a distributed system without conflicts; it ensures that the operations of multiple users can be merged without conflicts through mathematical properties (such as commutativity, associativity, and idempotency), and finally reaches a consistent state.

[0051] Subscription push: It is a message passing mode in which the receivers of messages (subscribers) actively receive push messages from the publishers of messages by subscribing to specific topics or channels. This mode is widely used in real-time notifications, event-driven architectures, and distributed systems.

[0052] Figure 1 The flowchart of a decentralized distributed real-time editing method according to an embodiment of the present application is shown, as Figure 1 shown, the method includes the following steps:

[0053] Step S101, deploy a decentralized draft service and at least one clip sub-service in each node.

[0054] In the embodiments of the present application, based on decentralized clip drafts and a distributed clip architecture, multiple nodes are enabled to collaborate on clipping the same clip project, greatly improving the clip efficiency and clip flexibility.

[0055] Among them, the original clip draft central service of the video clip system with a centralized architecture in the prior art is split into multiple clip sub-services according to business types. The multiple clip sub-services are independent of each other, achieving decoupling. The business types may include basic clipping, sticker clipping, subtitles, music, etc. Then, the multiple clip sub-services obtained by splitting may include basic clipping services, sticker clipping services, subtitle services, music services, etc., and a decentralized draft service is constructed. The decentralized draft service is used to call at least one clip sub-service through the service to achieve decentralized clip drafts. In a specific application scenario, the decentralized draft service and at least one clip sub-service can be customized and deployed in each node according to the clip requirements of each node. Among them, a node refers to a device with processing capabilities and storage resources, specifically a device installed with local clip software for users to perform video clipping.

[0056] Step S102: According to the clip operation performed by any node on the clip project, use the clip sub-service to which the clip operation belongs to process the corresponding business data in the clip draft data of the clip project to obtain an operation result.

[0057] Each node can participate in the same clip project. Each node can work independently and interact with other nodes. Among them, each node can perform a clip operation on the clip project, and the clip operation can be instantaneously synchronized to other nodes participating in the clip project without waiting for processing or uploading to complete.

[0058] When any node performs a clip operation on the clip project, in this node, use the clip sub-service to which the clip operation belongs to process the corresponding business data in the clip draft data of the clip project to obtain an operation result. For example, when a user adds some subtitle text to the clip project, that is, a subtitle insertion operation is performed through the node corresponding to the user, and the subtitle insertion operation belongs to the processing capabilities provided by the subtitle service. Then, use the subtitle service deployed in this node to process the corresponding subtitle data in the clip draft data of the clip project to add subtitle text, thereby obtaining an operation result, and display the clip effect of the clip operation in this node, so that the user can instantaneously view the clip effect during the clipping process.

[0059] Step S103: Use the decentralized draft service in the node to synchronize the operation result to other nodes for other nodes to apply the operation result to their clip projects.

[0060] In the embodiments of the present application, a real-time editing mechanism is introduced. By using distributed technology and real-time communication technology, it can achieve instant synchronization of editing operations and effect display. When a certain node performs an editing operation, it can immediately use the decentralized draft service in that node to synchronize the operation results of that node to other nodes participating in the same editing project in a broadcast manner or the like, without waiting for processing or uploading to complete, thus realizing real-time editing and collaborative work.

[0061] According to the decentralized distributed real-time editing method provided by the embodiments of the present application, based on decentralized editing drafts and a distributed editing architecture, a decentralized draft service and an editing sub-service are deployed in each node, maintaining the independence between the editing sub-services and effectively reducing the coupling; moreover, a real-time editing mechanism is introduced. By using distributed technology and real-time communication technology, when any node performs an editing operation, it can immediately synchronize the operation results of that node to other nodes participating in the same editing project, achieving instant synchronization of editing operations, enabling multiple nodes to efficiently and conveniently collaborate on editing the same editing project, and greatly improving the editing efficiency and editing flexibility.

[0062] Figure 2a The flowchart of the decentralized distributed real-time editing method according to another embodiment of the present application is shown as Figure 2a shown, and the method includes the following steps:

[0063] Step S201, split the original editing draft central service into multiple editing sub-services according to the business type, and construct a decentralized draft service.

[0064] In the embodiments of the present application, according to the business type, the original editing draft central service of the video editing system with a centralized architecture in the prior art is split into multiple independent editing sub-services, where the business type may include types such as basic editing, sticker editing, subtitles, music, transitions, filters, etc.

[0065] In a specific application scenario, when splitting the original editing draft central service according to the business type, the multiple editing sub-services obtained may be as Figure 2b shown. The multiple editing sub-services include a basic editing service, a sticker editing service, a subtitle service, a music service, a transition service, a filter service, etc. Each editing sub-service contains a corresponding business module, and the business module is responsible for processing the business data of the corresponding business type in the editing draft data. For example, the business module in the subtitle service is the subtitle module, and the subtitle module is used to process the subtitle data in the editing draft data; the business module in the sticker service is the sticker module, and the sticker module is used to process the sticker data in the editing draft data; the business module in the basic editing service is the basic editing module, and the basic editing module is used to process the video data in the editing draft data.

[0066] Moreover, a decentralized draft service is constructed, and a set of clip protocols for inter-node communication, data sharing, and collaborative work is set based on Conflict-Free Replicated Data Types (CRDT). The clip protocols may specifically include the protocols of each business module itself, the interface protocols for push subscriptions, the protocols for data addition and deletion, etc. Through the clip protocols, each node can safely access and modify the data of other nodes, realizing real-time clipping and collaborative work.

[0067] The service identifiers (such as service IDs) of each clip sub-service are recorded in the decentralized draft service. The service IDs correspond one-to-one with the clip sub-services. According to the service ID, the corresponding clip sub-service can be mapped or determined. Then, the decentralized draft service can call the corresponding clip sub-service through the service according to the clip protocol and the service ID. Each node can also share and update the business data corresponding to the business module through the ID, realizing a decentralized clip draft, as Figure 2b shown.

[0068] Step S202: According to the clip requirements of each node, deploy a decentralized draft service and at least one clip sub-service that meets the clip requirements in the node.

[0069] Considering that the clip requirements of each node participating in the same clip project are different, according to the clip requirements of each node, only a decentralized draft service and at least one clip sub-service that meets the clip requirements can be deployed in the node, thus realizing the customized deployment of the clip sub-service and helping to avoid resource waste of the node.

[0070] For example, if the clip requirements of node 1 are basic clipping and sticker clipping, it means that node 1 is responsible for handling basic clipping and sticker clipping in the clip project. Then, a decentralized draft service, a basic clipping service, and a sticker clipping service are deployed in node 1. For other clip sub-services, there is no need to deploy them in node 1. The decentralized draft service in node 1 calls the basic clipping service and the sticker clipping service in node 1 through the service, enabling the user on the node 1 side to perform basic clipping and sticker clipping; if the clip requirements of node 2 are subtitle clipping, it means that node 2 is responsible for handling subtitles in the clip project. Then, a decentralized draft service and a subtitle service are deployed in node 2. For other clip sub-services, there is no need to deploy them in node 2. The decentralized draft service in node 2 calls the subtitle service in node 2 through the service, enabling the user on the node 2 side to perform subtitle processing.

[0071] Step S203: For each node, store the business data corresponding to at least one clip sub-service deployed in the node in the clip draft data of the clip project in the node, or store the clip draft data of the clip project in the node.

[0072] In order to enable each node participating in the editing project to perform editing operations on the editing project, for each node, it is necessary to store the business data corresponding to at least one editing sub-service deployed by the node in the editing draft data of the editing project into the node, or store the editing draft data of the editing project into the node.

[0073] In a specific application scenario, if the data volume of the editing draft data of the editing project is large, in order to reduce the unnecessary occupation of the node storage resources, only the business data corresponding to the editing sub-services deployed by the node in the editing draft data can be stored into the node. For example, if node 1 deploys a basic editing service and a sticker editing service, only the video data and sticker data in the editing draft data can be stored into node 1, realizing the decentralized editing draft data. If the data volume of the editing draft data of the editing project is small or each user participating in the editing project wants to view the editing effects of each business part of the editing project, the entire editing draft data of the editing project can be stored into the node.

[0074] Step S204, according to the editing operation performed by any node on the editing project, use the editing sub-service to which the editing operation belongs to process the corresponding business data in the editing draft data of the editing project to obtain an operation result.

[0075] The embodiment of the present application adopts a distributed editing architecture, which does not rely on a central server or a single control point, but realizes communication and cooperation between nodes through an editing protocol. Each node can work independently and interact with other nodes to realize multi-node collaborative editing of the same editing project.

[0076] When any node performs an editing operation on the editing project, use the editing sub-service to which the editing operation belongs to process the corresponding business data in the editing draft data of the editing project, and display the editing effect of the editing operation in the node, so that the user on the node side can view the editing effect immediately during the editing process; and determine the business object corresponding to the editing operation, and generate an operation object corresponding to the editing operation as the operation result. Among them, the operation result contains the operation identifier (such as operation id) of the editing operation and the information of the business object. The operation identifier is the unique identifier of the editing operation and can be used to distinguish different editing operations.

[0077] Taking the business object as the caption object (CaptionInfo) as an example, the protocol provided externally can be:

[0078] data class CaptionInfo(

[0079] val id:String, / / unique identifier

[0080] var text: String, / / Subtitle text

[0081] var inPoint: Double, / / Start time (seconds)

[0082] var outPoint: Double, / / End time (seconds)

[0083] val tmpPath: String / / Associated file path

[0084] val color: Int / / Text color )

[0086] sealed class Operation {

[0087] data class Insert(val position: Int, val subtitle: CaptionInfo) : Operation()

[0088] data class Delete(val id: String) : Operation()

[0089] data class Update(val id: String, val subtitle: CaptionInfo) : Operation()

[0090] }

[0091] In the above protocol, a subtitle object (i.e., CaptionInfo) for managing subtitle information is defined, and an operation object (i.e., Operation) is encapsulated. The operation object is used to represent operations on subtitles, including insertion (Insert), deletion (Delete), and update (Update). Among them, the subtitle object CaptionInfo is a data class that contains the following properties: subtitle object id, subtitle text (text), start time (inPoint), end time (outPoint), associated file path (tmpPath), and text color (color).

[0092] For example, when a user modifies the color of the text, an operation object Operation corresponding to this clip operation will be generated. The operation object Operation contains information about the text, operation id, etc. This operation object is used as the operation result for synchronization between nodes. Another example is that when a user adds a local video, the local video of the user can be uploaded first to obtain a video address. The video address is placed into its corresponding business object, that is, a video object (such as VideoInfo), and an operation object Operation corresponding to this clip operation will be generated, and then it is synchronized to other nodes. After receiving it, other nodes will download and use it according to the video address in it. Similarly, the processing methods for adding local materials such as local music and local stickers are similar and will not be elaborated here.

[0093] Step S205: Use the decentralized draft service in the node to synchronize the operation result to other nodes for other nodes to apply the operation result to their clip projects.

[0094] Figure 2c Shows the interaction schematic diagram between nodes. For example, Figure 2c As shown, the local clip software is installed in each node. User 1 can perform clip operations on the clip project through the local clip software in its corresponding node, and User 2 can also perform clip operations on the clip project through the local clip software in its corresponding node. When any user performs a clip operation, the decentralized draft service in the node corresponding to this user is used to establish a connection for the clip service with other nodes and synchronize the operation result. Specifically, the connection for the clip service between nodes can be achieved through a decentralized clip protocol and real-time clip service subscription push. Among them, the clip protocol is set based on CRDT. The core principle of CRDT is to use the commutative law, associative law, and idempotency in mathematics to ensure that operations on data in a distributed environment can be executed in any order, and the final result remains the same.

[0095] Based on the distributed design of drafts and the subscription push mechanism, when a change occurs in a certain business module of a node, it is only necessary to trigger this business module to push an update message to other remote collaborators who are listening for changes in the business data corresponding to this business module. Here, the remote collaborator refers to other nodes that subscribe to listen for changes in this business data and receive push messages when changes occur.

[0096] Among them, the node can serialize the operation result into an operation string in a preset format. Using the decentralized draft service in the node, based on the subscription push mechanism, the operation string is broadcast to the neighbor nodes of this node through the clip protocol, and then through the neighbor nodes, the operation string is broadcast to the neighbor nodes of the neighbor nodes, and so on, until it can be broadcast to all other nodes of this node.

[0097] Specifically, the preset format can be the JSON format. The JSON format is a common data format that supports multiple programming languages and platforms. Serializing the operation result into an operation string in the JSON format can facilitate data transfer between nodes in different languages, has high cross-platform compatibility, and transmitting the operation string to other nodes via the broadcast method can achieve synchronous operations in a distributed environment, ensuring that all nodes execute the same operation and ultimately reaching a consistent state, thereby ensuring distributed consistency.

[0098] In the embodiment of the present application, since it is based on a decentralized clip draft and a distributed clip architecture, this node may not know which other nodes are participating in the same clip project with it. Then this node can broadcast the JSON-serialized operation object Operation to the known neighbor nodes, where the JSON-serialized operation object Operation is specifically an operation string in the JSON format. After receiving this broadcast operation string in the JSON format, the neighbor nodes of this node construct the corresponding operation object Operation according to the received operation string and then can apply it to their own local clip projects. At the same time, this neighbor node will synchronously broadcast it to the neighbor nodes it knows. Eventually, all other nodes of this node can receive this operation result.

[0099] Specifically, after an other node receives the broadcast operation string, this other node constructs an operation result according to the received operation string, parses the operation result to obtain the operation identifier of the clip operation, and then by comparing this operation identifier with the operation history record stored in itself, determines whether the operation history record contains the operation record corresponding to the operation identifier. If not, it means that this other node has not applied this operation result, and then this operation result is applied to the local clip project of this other node. If so, it means that this other node has already applied this operation result and there is no need to apply it again, so this operation result can be discarded. According to the principle of CRDT, the priorities will be sorted according to the timing of the broadcast operations, and the ones earlier in time will be applied first to avoid conflicts.

[0100] According to the decentralized distributed real-time editing method provided by the embodiments of the present application, based on the decentralized editing drafts, distributed editing architectures, and decentralized editing protocols, a decentralized draft service and editing sub-services are deployed in each node to achieve multi-node collaborative editing, and the independence between the editing sub-services is maintained, effectively reducing the coupling, improving the scalability and reliability, and greatly enhancing the editing efficiency and flexibility; moreover, real-time editing effects are achieved. When any node performs an editing operation, the user on the node side can instantaneously view the editing effects during the editing process, and the operation results of the node are instantaneously broadcast to other nodes through the editing protocol to keep in sync with other nodes, realizing the instant synchronization of editing operations; in addition, the editing protocol is set based on conflict-free replicated data types, effectively ensuring distributed consistency, avoiding conflicts, and facilitating better collaborative work among multi-nodes.
