in step S140, a video composition instruction is obtained, and the video to be clipped is clipped based on the audio track, the video information and the video composition instruction, so as to compose a target video.
Optionally, the method of the embodiment of the present disclosure is implemented based on an AVfoundation framework of the iOS system.
The embodiment of the disclosure is mainly applied to the mobile terminal, and the application range and the scene of the video clip are expanded, so that more users can perform the video clip, and the users can perform the video clip on the mobile terminal conveniently. In an embodiment of the present disclosure, a mobile terminal includes: the device can play video such as mobile phones, notebooks, tablet computers, vehicle-mounted computers and the like. The video processing method disclosed by the invention is based on the iOS client and realizes the playing, cutting and synthesizing of the video based on the AVFoundation framework of the iOS system.
In the embodiment of the disclosure, when a user records videos of the same audio in multiple scenes, or the user records videos of the same audio in multiple angles in the same scene, in order to enable videos recorded in the same audio to be presented in the same video in multiple angles. In the embodiment of the present disclosure, the recorded video to be clipped is imported into the mobile terminal, and since the AVPlayer in the AVFoundation frame can load a local video, which may be a video shot by the mobile terminal, or a video shot by another terminal is imported into a moving video, the AVFoundation frame further includes an AVPlayerLayer, which is mainly used for rendering and displaying on a video interface. Therefore, on the basis of the foregoing, the AVPlayer in the AVFoundation frame loads the local video, and the AVPlayer layer realizes rendering and display of the video on the video display interface of the mobile terminal, so as to realize the video play and preview function, specifically, as the imported multiple videos (at least including two videos) are played synchronously on the video interface through the AVPlayer layer, as shown in fig. 2, the multiple videos are the video display interface of the mobile terminal, and include a video track, a main video play interface, a video preview interface, and a virtual play control. Of course, it may also include other items, such as an audio track pull bar, and when the audio track pull bar is included, since the audio and the video are synchronized, it is further convenient for the first video to be played, and the video can be pulled to start playing from the first frame of the video. Specifically, the video to be clipped of the user includes four videos (video 1, video2, video3, and video4, respectively), the four videos to be clipped are simultaneously displayed on the video preview interface on the mobile terminal, and because the four videos to be clipped have the same audio track, the four videos to be clipped can be synchronously played on the video preview interface under the same audio track. The method comprises the steps that a user triggers a main video selection instruction through a finger or other devices on a video preview interface, namely, a video to be clipped displayed on the main video interface is triggered, the video to be clipped selected by the user is played on the main video playing interface, after the currently played video to be clipped plays a part of frames on the main video playing interface, the user selects another video to be clipped on the video preview interface, namely, the main video selection instruction is triggered again on the video preview interface, the other video to be clipped selected by the user is played on the main video playing interface, the video to be clipped selected by the user is played on the main video playing interface when the current video to be clipped is selected by the user, the purpose of simultaneously playing a plurality of videos to be clipped on a mobile terminal is achieved, and the video to be clipped is convenient for the user to switch.
With the above process, when the video to be clipped is played on the main video playing interface, video information for synthesizing the target video, which is played on the main video playing interface by the video to be clipped, is synchronously recorded, where the video information includes: the starting point of the video to be clipped is played, the length of the video segment to be clipped, the identification of the video to be clipped and the sequence of the video segment to be clipped. With the audio track pull bar, the starting point is the user-selected playing point of the video to be edited. If the video to be edited on the main video playing interface is switched to another video to be edited, the other video to be edited is switched to the main video playing interface in a pause state, the user pulls the audio track pulling strip to pull the video to the audio track of the last video playing end to the corresponding time point, at the moment, the user selects to play the video to be edited on the main video playing interface, and the video information of the video to be edited on the main video playing interface is synchronously recorded. Because the videos to be edited have the same audio track, when the videos to be edited played on the main video playing interface are switched to another video, the user can be reminded whether to switch the playing start frame of the switched videos to be edited to the time point on the audio track corresponding to the playing end frame of the last video to be edited, the process can also be set to be an automatic switching process based on the user, the video editing efficiency of the user is further improved, the user is prevented from manually searching for a conjunction point when the videos are played, and the accuracy of a plurality of videos under the same audio frequency of different videos is improved.
On the basis of the foregoing, based on the same audio track and the video information, when a user triggers a video composition instruction on the mobile terminal, the mobile terminal implements the clipping of a video to be clipped through AVURLAsset in the AVFoundation framework, and combines the clipped video segments together through avmultimedia communication to obtain a target video, which is described in detail later.
Optionally, in the step of sequentially playing, according to the main video selection instruction triggered on the video preview interface, the video to be clipped associated with the main video selection instruction on a main video playing interface, the following steps may be included.
According to the main video selection instruction triggered at the video preview interface at present, switching the video to be edited currently played at the main video playing interface into the video to be edited associated with the main video selection instruction;
synchronously recording the currently selected playing starting point of the video to be edited and the video segment length of the video to be edited currently played on the main video playing interface;
and the video to be edited played on the video preview interface and the currently selected video to be edited played on the main video playing interface are played synchronously.
With reference to the foregoing description, according to the main video selection instruction triggered by the user at the video preview interface currently, the video to be edited currently played on the main video play interface is switched to the video to be edited currently selected by the user; as shown in fig. 2 to fig. 6, after the user selects video1 on the video preview interface, the user clicks to play, then video1 is played on the main video play interface, the video track synchronously records the starting point of playing video1, when the user clicks to play video2, the main video play interface switches video1 to video2, the video track synchronously records the video segment length played by video1, the video segment identifier (i.e. the video to which the video segment belongs, such as video 1), the video segment order (i.e. the playing order, which may also be replaced by the real point and length of the video segment of video1 corresponding to the audio segment), and the starting point of playing video 2; when the user clicks the video4, the main video playing interface switches the video2 to the video4, and the video track synchronously records the length of the video segment played by the video2, the identification of the video segment (i.e. the video to which the video belongs, such as the video 2), the sequence of the video segment (i.e. the playing sequence, which can also be replaced by the real point and length of the video segment of the video2 corresponding to the audio segment), and the starting point of the playing of the video 4. As shown in fig. 7, main is the corresponding video track, video1, video2, video3, and video4 are the video tracks of video1, video2, video3, and video4, and timenge 1, timenge 2, and timenge 4 record the video information of video1, video2, and video4 played on the main video. Correspondingly, after the user selects the same video for multiple times, the video track corresponding to the video records multiple pieces of video information, for example, in fig. 7, one video track has multiple time intervals. When the main video is played, the video to be edited played on the video preview playing interface and the video to be edited played on the main video are synchronously played, so that the user can conveniently select the video to be edited which is satisfied by the user at the corresponding time point for playing, and the satisfaction degree of the user is improved. The synchronous playing also enables the video point and the audio point of the video clip to be clipped to be more fit, and enables the synthesized target video to be smoother.
In order to enable a user to watch videos on a main video playing interface and a video preview interface at the same time, the user can conveniently select switching between videos to be clipped, after the videos to be clipped are switched, the user does not need to drag the starting point of the video playing to be clipped again, the video to be clipped played on the main video playing interface and the video to be clipped played on the video preview interface are synchronously played, and the nodes of the videos played on the same audio track are ensured to be consistent. And when the video is switched, when the video to be edited played on the main video playing interface is switched to other videos on the video preview interface, the videos to be edited have consistent audio, namely, the video to be edited switched to the main video playing interface is only the conversion of images, and the corresponding audio is not changed and is not switched, so that the playing process of the audio is continuously carried out. Illustratively, in the AVFoundation framework, synchronous playing of a main video and a next preview video is realized through a plurality of AVPlayer instances, when a user selects a next video to be clipped, the top main player switches to the video source and plays a preview synchronously with the next video. And recording the CMTimeRange of the video source after the user selects to play each time, wherein the CMTimeRange is used for representing the starting point and the length of the video segment actively selected by the user on the video source. There may be multiple timesrange segments that need to be recorded on different video sources, as detailed in fig. 7.
Optionally, in the step of editing the video to be edited based on the audio track, the video information and the video composition instruction, and composing the target video, the following steps may be included.
Editing the video to be edited according to the starting point of playing the video to be edited, the length of the video segment to be edited and the identification of the video to be edited;
acquiring an audio track of any video to be edited;
and acquiring the video segments to be clipped according to the audio tracks and the video segment sequences to be clipped, and synthesizing the target video.
After the video previewing is completed or the video is played on the main video playing interface, the video to be clipped is clipped by combining the starting point of the video to be clipped playing, the length of the video segment to be clipped and the video identifier to be clipped, namely finding the starting point of playing the video to be clipped and the length of the video segment to be clipped under the corresponding video according to the video identifier to be clipped, and clips the video to be clipped through the aforementioned AVURLAsset, because the audio of the video to be edited is the same, before the video synthesis is carried out, the audio track of any video is obtained, the corresponding video segment is inserted into the corresponding video track based on the sequence of the video segment to be edited (or the video segment corresponding to the audio segment), and synthesizing the video segments and the audio together through AVMutableComponition to obtain the target video comprising the audio. The sequencing of the video segments is realized while the user watches the video, and then when the video is synthesized, the video segments are inserted into the corresponding audio tracks according to the marks of the video segments to be edited, so that the situation that the user conducts manual sequencing of the video to be edited again is avoided, and the video editing rate is improved.
In a specific implementation process, the avmultimedia position in the AVFoundation framework is used to implement the multi-segment synthesis of the video. The avmusablecomposition includes a video track and an audio track, and may acquire a corresponding track object through an AVMediaTypeVideo or an AVMediaTypeAudio, where the AVMediaTypeVideo acquires the video track object and the AVMediaTypeAudio acquires the corresponding audio track object. The AVURLAsset may load a local video source of the mobile terminal and obtain video duration information, a video track of a video to be clipped, and audio track information, that is, the video information, similarly, the video track information needs to be obtained through the AVMediaTypeVideo, or the AVMediaTypeAudio obtains corresponding audio track information, as shown in fig. 8. After the AVAssetTrack (track information) of each video to be edited is obtained, the corresponding video track segment can be inserted into the avmultimedia communication track of the avmultimedia communication according to the TimeRange selected by the user, so as to obtain the final target video. The audio tracks of the video sources can be selected at will, the audio tracks of the video sources are the same, the audio tracks of the video sources can be selected as the final audio tracks, the audio tracks of the video sources are the same, the audio track of the first video can be selected as the final audio track, and the audio tracks of other videos can be selected as the final audio track.
Optionally, after the step of editing the video to be edited based on the audio track, the video information and the video composition instruction to compose a target video, the method includes:
setting the target video storage information;
and exporting the target video to a database for storage according to the target video storage information.
Optionally, after the step of exporting the target video to a database for storage according to the target video storage information, the method includes:
and acquiring the target video from the database and playing the target video on a preview interface.
In the embodiment of the disclosure, after the target video is synthesized, in order to facilitate the video to be used by other application programs or facilitate a user to watch the target video subsequently, the target video is exported to a database, where the database may be a database local to the mobile terminal or a database of another terminal connected to the mobile terminal, such as a cloud database. When the target is the video, the information such as the format, the storage path and the like of the target video needs to be determined, so that the target video can be conveniently played in a corresponding playing process, and meanwhile, the target video can be stored in a corresponding database. In an embodiment of the present disclosure, in a specific implementation, after the video splicing is completed, the video may be derived through an avassetxortsession in the AVFoundation.
