It can be understood that data (including but not limited to the data itself, the acquisition or use of the data) involved in these technical solutions should comply with the requirements of corresponding laws, regulations and related regulations.

Before introducing these technical solutions, an exemplary description of an application scenario can be provided. The technical solutions of the embodiments of the present disclosure can be applied to any scenario in which audio and video data is edited. For example, a browser-based display interface can display audio and video data to be edited; when a triggering operation on the audio and video data to be edited is detected, target audio and video editing plug-ins can be determined from among the pre-built audio and video editing plug-ins to be used, so as to edit, based on the target audio and video editing plug-in, the audio and video data to be edited; and at the same time, target audio routings are created, so as to play the target audio and video data based on the target audio routings after the target audio and video data is obtained, so that the editing and play processes of the audio and video data to be edited can be realized on the browser display interface, achieving the effect of simplifying an audio and video data editing process.

FIG. 1 is a schematic flowchart of an audio and video editing method provided in an embodiment of the present disclosure. The embodiment of the present disclosure is suitable for the case of editing, based on a pre-built target audio and video editing plug-in, audio and video data to be edited, and playing the target audio and video data obtained after the editing. The method can be executed by an audio and video editing apparatus which can be implemented in the form of software and/or hardware, optionally, through an electronic device which can be a mobile terminal, a PC or a server, etc. The technical solution provided in the embodiment of the present disclosure can be executed based on a client, a server, or the cooperation between the client and the server.

As shown in FIG. 1, the method includes:

S110, when it is detected that audio and video data to be edited is triggered to be played, acquiring each audio and video editing plug-in to be used.

The audio and video data to be edited may be a multimedia data stream that stores sound content and image content. At the same time, the sound content and image content stored in this data stream may be sound information and image information that the user currently needs to edit. The audio and video data to be edited may also be a data stream that needs to be re-edited. For example, re-editing may include: storage, cropping, play control, reverberation, filtering, etc. for audio and video data. For example, the audio and video data to be edited may be any audio and video clips that need to be edited. In the practical application process, a plurality of audio and video data may be uploaded to a system, and a play trigger control may be set in any area of these audio and video data. When a trigger operation on the play trigger control of any audio and video data is detected, this audio and video data can be used as the audio and video data to be edited, and each audio and video editing plug-in to be used is acquired.

The audio and video editing plug-ins to be used may be functional plug-ins capable of editing audio and video data. For example, the audio and video editing plug-ins to be used may include noise reduction editing plug-ins, volume editing plug-ins, hot key editing plug-ins, reverb editing plug-ins, export editing plug-ins, fade-in and fade-out plug-ins, etc.

Optionally, the audio and video editing plug-ins to be used include a plurality of hook files which include function files used to edit the audio and video data to be edited.

In this embodiment, the hook files may be files used to perform audio and video editing operations. Optionally, the hook files may include, but are not limited to, a hook file for playing audio and video data to be edited (play), a hook file for playing tracks (play Track), a hook file for playing clips (play Clip), a hook file for stopping playing (stop), a hook file for changing content (content Change), a hook file for changing selections (selection Change), a hook file for destroying audio and video data to be edited (destory), etc. It should be noted that the hooks in the audio and video editing plug-ins to be used can be determined based on the developer's needs, and in the subsequent application process, newly generated hook files can be sent to each audio and video editing plug-in to be used at any time. The advantages of such setting lie in that a recording module in target audio routings can be created, the target audio routings can be expanded, and a variety of audio editing effects can be achieved.

For example, the architecture of a plug-in system containing audio and video editing plug-ins to be used can be described with reference to FIG. 2: the containing relationship of the plug-in system can be that an audio editor includes a plug-in management module which contains at least one audio and video editing plug-in to be used, wherein each audio and video editing plug-in to be used contains a plurality of hook files. The hook files contained in the audio and video editing plug-ins to be used can include a hook file for playing audio and video data to be edited, a hook file for playing tracks, a hook file for playing clips, a hook file for stopping playing, a hook file for changing content, a hook file for changing selections, and a hook file for destroying audio and video data to be edited.

The hook file for playing audio and video data to be edited can be triggered once when a trigger operation of the audio and video data to be edited is detected; the hook file for playing tracks can be triggered once in the case where a trigger operation of any track data in the audio and video data to be edited is detected when the audio and video data to be edited being played, and by triggering this hook file, a connection method of target audio routings, web audio interface context and track data can be acquired; the hook file for playing tracks can be triggered once in the case where a trigger operation of any audio clip data in the audio and video data to be edited is detected when the audio and video data to be edited being played, and by triggering this hook file, a connection method of target audio routings, web audio interface context and track data can be acquired; the hook file for stopping playing can be triggered once when a stop play operation is detected; the hook file for changing content can be triggered once when audio and video state management data changes; the hook file for changing selections can be triggered once when the area to be edited of the audio and video data to be edited changes; and the hook file for destroying audio and video data to be edited can be triggered once when the audio editor is destroyed.

In the practical application process, the audio and video editing plug-ins to be used can be pre-stored in a system plug-in library in the early development stage. When it is detected that a user triggers the play control of the audio and video data to be edited, each audio and video editing plug-in to be used can be directly retrieved from the plug-in library.

It should be noted that the audio and video editing plug-ins to be used in the plug-in library are in a dynamic update state. When other audio and video editing plug-ins are developed based on user needs in the subsequent application process, these subsequently developed audio and video editing plug-ins can be updated to the plug-in library as audio and video editing plug-ins to be used, so that when an editing operation of the audio and video data to be edited is subsequently detected, each audio and video editing plug-in to be used can be called.

It should also be noted that the number of audio and video editing plug-ins to be used and the functions that can be implemented can be set based on actual needs, that is, each audio and video plug-in to be used can correspond to a plug-in management system which is extensible, and each audio and video editing plug-in to be used in the plug-in management system can be updated at any time.

In a specific implementation, when the user wants to edit any audio and video to be edited, the user can input a trigger operation into a play trigger control of the audio and video data to be edited. When it is detected that the audio and video data to be edited is triggered to be played, each audio and video editing plug-in to be used can be acquired, so as to process, based on each audio and video editing plug-in to be used, the audio and video data to be edited.

S120, determine target audio and video editing plug-ins according to pre-received audio and video state management data and each audio and video editing plug-in to be used.

In this embodiment, the audio and video state management data can be used to represent all data expressions of the audio and video data to be edited during the editing process. The audio and video state management data may include all data applied to the editing of the audio and video data to be edited. Optionally, the audio and video state management data may include track data, audio data, audio effect parameters, audio meta information, global configuration data, etc. For example, the audio and video state management data can be represented by JSON. The target audio and video editing plug-ins may be plug-ins that edit the audio and video data to be edited. It should be noted that the target audio and video editing plug-ins may be one plug-in among the audio and video editing plug-ins to be used, or may be a plurality of plug-ins among the audio and video editing plug-ins to be used.

In practical applications, corresponding audio and video state management data can be generated based on the editing operation of the audio and video data to be edited. When an audio and video editing interface is opened, the pre-generated audio and video state management data can be sent to the audio and video editing system, so that when the user's play trigger operation of the audio and video data to be edited is detected, the editing operation to be performed on the audio and video data to be edited can be determined based on the audio and video state management data.

In the practical application process, when the target audio and video editing plug-ins are determined in each audio and video editing plug-in to be used, each audio and video editing plug-in to be used can be traversed according to the audio and video state management data. When it is detected that the audio and video state management data contains fields corresponding to at least one audio and video editing plug-in to be used, these audio and video editing plug-ins to be used can be used as target audio and video editing plug-ins.

Optionally, determining target audio and video editing plug-ins according to pre-received audio and video state management data and each audio and video editing plug-in to be used includes: determining the number of tracks based on the audio and video state management data, and calling corresponding track data in sequence; being based on collections of data corresponding to at least one piece of audio and video editing feature data in the track data and the audio and video state management data; and for each audio and video editing plug-in to be used, if the audio and video editing plug-in currently to be used includes the audio and video editing feature data in the collections of data, determining that the audio and video editing plug-in currently to be used is the target audio and video editing plug-in.

Those skilled in the art should understand that tracks are parallel “tracks” displayed one by one in audio editing software. Each track defines the properties of the track, such as the track's timbre, timbre library, channel number, input/output port, volume, etc. Correspondingly, the track data may be data used to characterize the properties of the track. Optionally, the track data can be used to describe the details, location, play duration, etc. of the tracks. The audio and video editing feature data may be data used to characterize audio and video editing properties.

In a specific implementation, after each audio and video editing plug-in to be used is acquired, in order to determine target audio and video editing plug-ins in each audio and video editing plug-in to be used, the pre-received audio and video state management data can be parsed; the number of tracks is determined according to the audio and video state management data; and track data is called sequentially. Further, collections of data corresponding to at least one piece of audio and video editing feature data are determined from among the audio and video state management data, and each audio and video editing plug-in to be used is traversed according to each audio data and each collection of data. For each audio and video editing plug-in to be used, if data that matches the audio and video editing feature data in each collection of data is detected in the audio and video editing plug-in currently to be used, the current audio and video editing plug-in can be used as the target audio and video editing plug-in. The advantage of such setting lies in that target audio and video editing plug-ins corresponding to the audio and video state management data can be determined from among a plurality of audio and video editing plug-ins to be used, so that the effect of editing, based on user needs, the audio and video data to be edited can be achieved.

S130, based on functional modules that are integrated in the target audio and video editing plug-ins, edit the audio and video data to be edited, so as to obtain target audio and video data.

The functional modules can be a collection of program elements such as data descriptions and executable statements. In this embodiment, the functional modules may be a collection of execution statements and data containing specific functions that the target audio and video editing plug-ins can implement. It should be noted that different target audio and video editing plug-ins can realize different audio and video editing functions. Therefore, the data files contained in the functional modules integrated in each target audio and video editing plug-in are also different. In the practical application process, the functional modules integrated in the target audio and video editing plug-ins can be dynamically adjusted, and which specific functional modules are included in the target audio and video editing plug-ins can be determined based on the user's current needs during each editing process.

In this embodiment, the target audio and video data may be a multimedia data stream that stores sound content and image content. At the same time, the sound content stored in this data stream may be sound information that meets the user's current needs.

In the practical application process, after the target audio and video editing plug-ins are determined, the functional modules integrated in the target audio and video editing plug-ins can be determined, and the audio and video data to be edited is edited based on audio and video editing execution statements contained in the functional modules, so that the audio and video data to be edited can be edited into audio and video data that meets the user's current needs. At this time, the audio and video data obtained after the editing can be used as target audio and video data. For example, if the target audio and video plug-ins are volume editing plug-ins and the editing data contained in the functional modules integrated therein is to adjust the volume to “1”, the finally obtained target audio and video data is audio and video data that adjusts the volume of the audio and video data to be edited to “1”.

It should be noted that when the audio and video data to be edited is edited based on the functional modules that are integrated in the target audio and video editing plug-ins, in the case of a plurality of target audio and video plug-ins, each target audio and video editing plug-in can be traversed. At the same time, since the audio and video data to be edited would be played based on a terminal device after the editing ends and the target audio and video data is obtained, in order to realize a play function of the target audio and video data, corresponding target audio routings will be generated after each target audio and video editing plug-in processes the audio and video data to be edited, so as to play the target audio and video data based on the target audio routings. It should also be noted that in order to realize the function of playing the target audio and video data based on the target audio routings, an audio processing module that contains both input and output can also be created to connect the target audio and video data to its corresponding play terminal, thereby achieving play.

Based on this, the process of determining target audio and video editing plug-ins and editing, based on the target audio and video editing plug-ins, the audio and video data to be edited also includes: creating a recording module to connect to the target audio routings.

In this embodiment, the recording module may be a module that processes audio and video data and can implement play of the processed audio and video data. A target audio routing may be an audio processing graph that is built from audio modules linked together. The target audio routings may contain a plurality of modules, optionally a data source module, a recording module, a destination module, etc. The target audio routings can control the creation of the modules contained therein, as well as the execution of audio processing or data stream decoding, etc.

In the practical application process, during the process of editing the audio and video data to be edited based on the target audio and video editing plug-ins, in order to connect the processed audio and video data to be edited to the play terminal for play, a corresponding recording module can be created, and the recording module is connected to the target audio routings, so that the processed audio and video data to be edited can be connected to a predetermined destination after being output. The advantage of such setting lies in that the construction of the target audio routings can be realized, so that the target audio and video data can be played based on the constructed target audio routings, thereby realizing the play function of the target audio and video data.

S140, play the target audio and video data based on target audio routing(s).

In this embodiment, after the target audio and video data is obtained, the target audio and video data can be played according to various modules that are connected in sequence in the target audio routings.

It should be noted that if there are a plurality of target audio and video editing plug-ins, corresponding target audio routings will be generated after editing the audio and video data to be edited based on each target audio and video editing plug-in is completed. However, when the target audio and video data is played based on target audio routing(s), a target audio routing that is finally used to play the target audio and video data can be determined from among various target audio routings, so that the target audio and video data can be played based on the determined target audio routing.

Based on this and the above technical solutions, the method also includes: using the target audio routing corresponding to the last target audio and video editing plug-in as the target audio routing that is finally used to play the target audio and video data.

In the practical application process, target audio routings corresponding to each target audio and video plug-in will be generated after the audio and video data to be edited is edited by a plurality of target audio and video editing plug-in. After all target audio and video editing plug-ins are traversed, the target audio routing corresponding to the last target audio and video editing plug-in can be used as the target audio routing that is finally used to play the target audio and video data, so that this target audio routing can be used to play the target audio and video data. The advantages of such setting lie in that the play function of the target audio and video data can be realized, and the visualization of an audio and video data editing process can be achieved.

It should be noted that the audio and video editing system provided in this embodiment may also include a selection management module (Selection Manager) and a clopboard management module (Clopboard Manager). In the Selection Manager, Selection can be described in seconds, and deletion, copy and other operations can be performed on the audio and video data to be edited through selections; and the Clopboard Manager provides a clopboard which can perform corresponding operations on the audio and video data to be edited and also depends on the Selection Manager.

For example, the specific execution process of the audio and video editing method can be described in conjunction with FIG. 3.

As shown in FIG. 3, when a play operation of the audio and video data to be edited is detected, each audio and video editing plug-in to be used can be obtained; each audio and video editing plug-in to be used is traversed based on a plug-in management module; play Track is called in turn according to the number of tracks (Track) in the audio and video state management data, and corresponding track data, namely a track 1 and a track 2, is uploaded; based on the track data and audio and video editing feature data (Attributes) in the audio and video state management data, the target audio and video plug-ins are determined as noise reduction editing plug-ins and volume editing plug-ins from among the audio and video editing plug-ins to be used, and a corresponding recording module (Audio node) is created to connect to the target audio routings (Audio Routing Graph); play Clip is called in turn according to the number of audio clips (Clip) in the audio state management data, and corresponding audio clip data is uploaded, that is, the track 1 includes an audio clip 1, an audio clip 2 and an audio clip 3, and the track 2 includes the audio clip 1; based on the audio clip data and the audio and video editing feature data (Attributes) in the audio and video state management data, the target audio and video plug-ins are determined as noise reduction editing plug-ins and volume editing plug-ins from among the audio and video editing plug-ins to be used, and a corresponding recording module (Audio node) is created to connect to the target audio routings (Audio Routing Graph); and after the traversal of each target audio and video editing plug-in is completed, the target audio and video data can be played according to the target audio routing (Audio Routing Graph) corresponding to the last target audio and video editing plug-in.

FIG. 4 is a schematic flowchart of an audio and video editing method provided in an embodiment of the present disclosure. Based on the foregoing embodiments, the audio and video data to be edited can be determined from among the uploaded audio and video data to be processed, and the audio and video state management data can be acquired, so as to edit, based on the audio and video state management data, the audio and video data to be edited, referring to the technical solution of this embodiment for its specific implementation. The technical terms that are the same as or corresponding to the above embodiments will not be described again here.

As shown in FIG. 4, the method specifically includes the following steps:

S210, receive at least one uploaded audio and video data to be processed, so as to determine, based on the at least one audio and video data to be processed, audio and video data to be edited.

In this embodiment, the audio and video data to be processed may be audio and video data that currently needs to be processed and uploaded to the audio and video editing system. There can be one or more audio and video data to be processed. When there is one piece of audio and video data to be processed, this audio and video data to be processed can be used as the audio and video data to be edited; and when there are a plurality of pieces of audio and video data to be processed, the audio and video data to be edited can be determined, based on user needs, from among the plurality of pieces of audio and video data to be processed.

It should be noted that the audio and video data that needs to be processed can be uploaded to the system in real time or periodically, so that the audio and video data to be edited can be determined based on the uploaded audio and video data to be processed.

In the practical application process, the audio and video data to be processed that needs to be edited can be uploaded to the system, and the uploaded audio and video data to be processed can be stored in a database. When an editing trigger operation of the audio and video data to be processed is detected, the audio and video data to be processed can be displayed in a display interface through a list or other display forms, so that the user can select among the audio and video editing data to be processed, so as to determine audio and video data to be edited. Another implementation method can lie in that: after the uploaded audio and video data to be processed is stored in the database, audio and video data filtering conditions can be entered in a search box displayed in the display interface, so as to filter, based on the filtering conditions entered by the user, the audio and video data to be processed. At this time, the audio and video data to be processed that is displayed in the filtering result display interface can be used as audio and video data to be edited.

S220, acquire audio and video state management data, so as to edit, based on the audio and video state management data, the at least one audio and video data to be edited.

In this embodiment, after the audio and video data to be processed is uploaded to the system, in order to determine all data expressions of the audio and video data to be edited in the entire editing process, audio and video state management data can be acquired before the audio and video data to be edited is edited, so as to determine target audio and video editing plug-ins based on at least one piece of audio and video editing feature data contained in the audio and video state management data, so that the audio and video data to be edited can be edited based on the target audio and video editing plug-ins.

Optionally, acquiring audio and video state management data includes: acquiring at least one piece of audio and video editing feature data corresponding to a state object, and updating the audio and video state management data based on the at least one piece of audio and video editing feature data.

The state object may be an object with instance variables, can save data, and is not thread-safe. In this embodiment, the audio and video editing feature data can be stored in the state object, and the audio and video editing feature data can be read and written at any time.

In the practical application process, when audio and video state management data is determined, at least one piece of audio and video editing feature data corresponding to the state object can be first acquired, and the audio and video state management data is updated according to the audio and video editing feature data to make the audio and video state management data contain various attribute features in the audio and video editing process, so that target audio and video editing plug-ins that edit the audio and video data to be edited can be determined based on the audio and video state management data. The advantage of such setting lies in that an editing function to be implemented in the audio and video editing process can be determined, so that the selection of the target audio and video editing plug-ins can be implemented.

It should be noted that the audio and video state management data also includes various attribute feature data of audios, and these data can be set based on user needs.

It should be noted that the audio and video state management data contains all data of the audio and video data to be edited during the editing process. When the user has editing needs for the audio and video data to be edited, the audio and video state management data can be changed, so as to edit, based on the changed audio and video state management data, the audio and video data to be edited. At the same time, each time the audio and video state management data changes, the target audio routings used to play the target audio and video data will also change accordingly.

Based on this and the above technical solutions, the method also includes: when a change in the audio and video state management data is detected, traversing, based on an audio management module, the audio and video data to be edited, so that the audio and video data to be edited is edited based on the updated audio and video state management data.

The audio management module may be a collection of data used for audio and video data management.

In practical applications, when a change in the audio and video state management data is detected, the audio management module can be triggered. Furthermore, the audio management module can traverse, according to the changed audio and video state management data, all audio clips in the audio and video data to be edited, and re-create the modules connected in the target audio routings, so as to realize a mapping relationship between the updated audio and video state management data and the audio editing system based on the re-created target audio routings. The advantages of such setting lie in that the editing process of the audio and video data to be edited is simplified, and the editing efficiency is improved; in addition, the editing process can be changed at any time, thereby improving the user experience.

It should also be noted that during the practical editing process, situations where the currently performed editing operation needs to be undone and restored to the state before editing will be encountered. At this time, a history management module used for storing data of each editing operation can be created, so that when an undo operation is detected, data required by the user can be retrieved from this module.

Based on the above technical solutions, the method also includes: after audio and video state management data is determined, saving the audio and video state management data to a history management module, so as to retrieve, when an undo or rollback editing instruction corresponding to the audio and video data to be edited is received, corresponding audio and video state management data from the history management module for editing the audio and video data to be edited.

In this embodiment, the history management module may be a collection used to store data corresponding to each editing operation during the editing process. The undo or rollback editing instruction may be a pre-written program code which can be used to perform the undo or rollback operation. In the practical application process, the undo or rollback control can be set in advance in any area in an audio and video editing interface. When the user's trigger operation of the undo or rollback control is detected, an undo or rollback editing instruction can be generated and sent to a server, so that the server can respond to the undo or rollback editing instruction when receiving same.

In a specific implementation, after audio and video state management data is determined, the audio and video state management data can be stored in a history management module, and each time a change in the audio and video state management data is detected, the changed audio and video state management data can be stored in the history management module. At the same time, the audio and video state management data previously stored in the history management module will not be deleted.

Further, when a user's trigger operation of the pre-set undo or rollback control is detected, an undo or rollback editing instruction can be generated and sent to the server. When the server receives the undo or rollback editing instruction, corresponding audio and video state management data can be retrieved from the history management module, so as to re-edit, based on the retrieved audio and video state management data, the audio and video data to be edited. The advantages of such setting lie in that historical editing operation data can be stored, which facilitates its subsequent calling at any time; and when a fault occurs, troubleshooting can be carried out based on the pre-stored audio and video state management data.

It should be noted that each time the audio and video state management data changes, the audio and video state management data is stored in the history management module, so that the history management module stores audio and video state management data in various states; and the undo or rollback editing operation is to undo the editing operation at the current time, so that the audio and video data to be edited is rolled back to the state before editing. At this time, if the audio and video state management data needs to be retrieved from the history management module, the audio and video state management data corresponding to this undo or rollback editing operation can be determined from among a plurality of pieces of audio and video state management data corresponding to the data to be edited, so as to edit, based on the retrieved audio and video state management data, the audio and video data to be edited.

Based on this and the above technical solutions, the method also includes: when an undo or rollback control is detected, acquiring from the history management module the audio and video state management data with the minimum distance from the current time, and multiplexing the audio and video state management data.

The current time can be a trigger moment of the undo or rollback control.

In practical applications, while saving the audio and video state management data to the history management module, corresponding timestamps are generated, so that the audio and video state management data is stored in the history management module in the order of time displayed by the timestamps. When the trigger operation of the undo or rollback control is detected, the current time can be determined. When corresponding audio and video state management data is retrieved from the history management module, the audio and video state management data with the minimum distance from the current time can be determined according to the current time and the timestamps corresponding to each audio and video state management data; this audio and video state management data is used as audio and video state management data corresponding to the undo or rollback operation; and the audio and video data to be edited is edited again based on this audio and video state management data, so that the audio and video data to be edited can be rolled back to the state required by the user. The advantage of such setting lies in that when an undo or rollback operation is detected, corresponding audio and video state management data can be quickly retrieved, so that the undo or rollback function can be quickly implemented.

S230, when it is detected that audio and video data to be edited is triggered to be played, acquire each audio and video editing plug-in to be used.

S240, determine a target audio and video editing plug-in according to pre-received audio and video state management data and each audio and video editing plug-in to be used.
