Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to implement synchronous playing of a main video and a sub video, embodiments of the present invention provide a video playing method, an apparatus, an electronic device, and a machine-readable storage medium, which are described in detail below.
The video playing method provided by the embodiment of the invention can be applied to intelligent terminals such as smart phones, tablet computers, smart televisions and smart homes, and can also be applied to a system formed by a front-end display screen and a rear-end server, and the system is hereinafter referred to as electronic equipment.
An embodiment of the present invention provides a video playing method, which may include the following steps as shown in fig. 1.
S101, in the playing process of the main video, detecting a first interaction interval played by the main video currently.
S102, searching a first sub video buffer area corresponding to the first interaction interval according to the preset corresponding relation between the interaction interval and the sub video buffer area, wherein the sub video buffer area is used for buffering the sub video related to the video clip of the main video in the interaction interval.
And S103, extracting the buffered first sub-video from the first sub-video buffer area.
And S104, when the main video is continuously played, the first sub video is played on the same screen.
By applying the embodiment of the invention, in the playing process of the main video, the first interactive interval played by the main video at present is detected, the first sub video buffer area corresponding to the first interactive interval is found out according to the preset corresponding relation between the interactive interval and the sub video buffer area, the buffered first sub video is extracted from the first sub video buffer area, and when the main video is continuously played, the first sub video is played on the same screen. During the playing process of the main video, detecting a first interactive interval currently played by the main video, wherein the interactive interval played by the main video corresponds to a sub video buffer area for buffering the associated sub video, so that, the first sub video buffer corresponding to the first interactive interval to which the main video is currently played can be found, the first sub video is extracted from the first sub video buffer, the first sub-video is a sub-video associated with a video segment of the main video within the first interaction interval, and at this time, besides continuing to play the main video, the extracted first sub video is played on the same screen, since the video clip in the first interaction interval to which the main video is currently played has an association with the first sub video, and the main video and the first sub video are played on the same screen, so that the synchronous playing of the main video and the related sub video is realized.
The video playing method provided by the embodiment of the invention is suitable for scenes of interactive videos, and the interactive videos are in an exchange mode in which online multiple people chat, perform, sing, teaching and the like are carried out in the same network video environment in a video mode. The main video refers to a video currently being played, the playing of the main video may be a player instance created in advance based on a graphics rendering interface, the created player instance is used to play the main video, and the main video is generally played while buffering, that is, a video segment in a time period is buffered in a buffer area, and then the buffered video segment is read from the buffer area to be played, so the graphics rendering interface mentioned here may be an OpenGL (OpenGraphics Library ) graphics rendering interface, a Metal graphics rendering interface, and the like based on the buffer area.
The interactive interval is a time period of the main video playing, the interaction between the electronic device and the user is provided in the interactive interval, and the user can view sub-videos associated with the video clips in the interactive interval, such as a video clip catwalk, video clips captured at different viewing angles, and the like. The main video can be divided into a plurality of interaction intervals, and each interaction interval can be used for allowing a user to view the sub video related to the main video.
Here, the associated sub-videos are exemplified: if a tv play is currently being played, the associated sub-video may be a feature video of the tv play, or a video clip of the tv play including a grandma, or a video of the tv play at other shooting angles; if the table tennis game is currently played, the associated sub-video can be the video of only one table tennis player in the table tennis game, or the video of the table tennis game at other shooting angles.
If the main video is detected to be currently played to the first interaction interval, it is indicated that interaction with a user for the first interaction interval is started, and a corresponding relationship between the interaction interval and the sub-video buffer is preset, for example, the sub-video buffer 1 corresponding to the interaction interval of 0-10 minutes of the main video, the sub-video buffer 2 corresponding to the interaction interval of 10-15 minutes of the main video, and the like, the first sub-video buffer corresponding to the first interaction interval can be found according to the preset corresponding relationship, and because the first sub-video related to the video segment of the main video in the first interaction interval is buffered in the first sub-video buffer, the first sub-video can be directly extracted from the first sub-video buffer.
The sub-video associated with the video segment in an interaction interval can be multiple, and the sub-videos can be buffered in the same sub-video buffer or different sub-video buffers. For the situation that a plurality of sub-videos associated with a video clip are buffered in the same sub-video buffer, a plurality of sub-videos can be extracted from the sub-video buffer; for the situation that a plurality of sub-videos associated with a video clip are respectively buffered in different sub-video buffers, each sub-video can be respectively extracted from each sub-video buffer to obtain a plurality of sub-videos.
After the first sub-video is extracted from the first sub-video buffer area, the first sub-video can be played on the same screen while the main video is continuously played, the content of the continuously played main video is a video clip in the first interaction interval, and the first sub-video played on the same screen is a sub-video related to the video clip, so that the purpose of synchronously playing the main video and the related sub-video is achieved.
In one implementation, the video clips in each interactive interval in the main video are respectively buffered in each buffer area, the sub-video associated with the video clips in each interactive interval are buffered in each sub-video buffer area, each buffer area corresponds to each sub-video buffer area, when synchronous playing is performed, each buffer area can be aligned with each sub-video buffer area according to the alignment mode shown in fig. 2, when playing is performed, a player instance is respectively created by using a specific graphics rendering interface, synchronous playing of the main video and the sub-video is realized through the modes of buffer area loading and sub-video buffer area loading, if the buffer area for buffering the video clips in the first interactive interval is the buffer area 3, the main video and the first sub video are loaded from the beginning of the buffer 3 and the beginning of the sub video buffer 3 using the two player instances created.
In an implementation manner of the embodiment of the present invention, in order to ensure that the sub-video has good fluency during the playing process, before the first sub-video is extracted from the first sub-video buffer, it is necessary to determine that all the first sub-videos associated with the video segments in the first interaction interval have been buffered, and only on the premise that all the first sub-videos have been buffered, the first sub-video is extracted from the first sub-video buffer.
Optionally, before executing S104, the method provided in the embodiment of the present invention may further execute the following steps: and creating a player example based on a preset graphic rendering interface. Correspondingly, S104 may specifically be: and when the main video is continuously played, the first sub video is played on the same screen by using the created player example.
In one implementation, because the main video and the sub video are both buffered and played, the player instances playing the main video and the sub video can be created based on a Metal graphics rendering interface.
Fig. 3 is a schematic flowchart of an embodiment of creating a player example based on a Metal graphics rendering interface, as shown in fig. 3, a CMSampleBufferRef (original binary data of a video) represents binary data contained in a buffer of a video file and a description corresponding to the binary data; CVPixelBufferRef (core video pixel buffer data) is a buffer pointer extracted from CMSampleBufferRef, the buffer pointer pointing to buffer data made up of pixel data; the CVMetalTextureRef (Metal texture data) is texture data corresponding to the CVPixelBufferRef and capable of being analyzed by the Metal graphic rendering interface, namely the CVMetalTextureRef is converted by the CVPixelBufferRef; the developer converts the CVMetalTextureRef into a general id data type (id < mtltissue >), and sends the id data type to a GPU (Graphics Processing Unit), and the GPU renders the final texture data.
And continuing to play the main video on the display interface, and after a player instance for playing the sub video is created, performing on-screen playing on the first sub video and the main video by using the created player instance. Since the sub-video is a video temporarily viewed by a user and the main video is a video mainly viewed by the user, when the main video and the sub-video are played synchronously, in order not to affect the playing of the main video, only a picture is loaded to play and audio is not loaded when the sub-video is played. Of course, in another implementation, both the screen and the audio can be loaded, and an option is provided on the interface to allow the user to select whether to listen to the audio of the main video or the audio of the sub video.
Optionally, the interaction interval may correspond to a plurality of first sub video buffers, and/or a plurality of first sub videos are buffered in the first sub video buffers. Before executing S104, the method provided in the embodiment of the present invention may further execute the following steps: at least one player instance is created based on a preset graphical rendering interface. Correspondingly, S104 may specifically be: when the main video is continuously played, switching and playing each first sub video on the same screen by using a player example according to a preset switching playing strategy; or when the main video is continuously played, the first sub videos are respectively played on the same screen by using a plurality of player instances.
The number of the sub-videos associated with the video segment in one interactive interval may be multiple, and these sub-videos may be buffered in the same sub-video buffer or different sub-video buffers, so that multiple first sub-videos may be extracted from the first sub-video buffer. In another embodiment, in order to facilitate the user to know the content focused on by the user in the same time period, the created player instance may be used to play the first sub-videos in the same screen in a switching manner according to a preset switching play strategy, or multiple player instances may be created, and the multiple player instances are used to play the first sub-videos in the same screen.
The preset switching playing strategy may include switching playing according to the sequence of the relevance degree from high to low, switching playing according to a preset playing sequence of the sub-videos of the specified type, switching playing according to user configuration, and the like.
In one implementation manner, the association degree between the sub video and the main video may be determined according to the type, size, and the like of the sub video, and when the switching playing is performed, the switching playing may be performed on each first sub video according to the association degree between each first sub video and the main video. For example, the extracted first sub-videos include a Flock video 1, a Flock video 2, a Flock video 3, an other view video 1, and an other view video 2, which are respectively associated with the main video by: 80%, 65%, 55%, 85%, 60%, therefore, the other perspective video 1, the feature video 2, the other perspective video 2, and the feature video 3 may be played in a switching order of the degree of association from high to low.
In another implementation manner, when the switching playing is performed, each first sub video may also be switched to be played according to a preset playing sequence of the sub video of the designated type. For example, the preset playing sequence of the sub-videos of the designated type is to play the catkin video first, then play the single character video, and then play the videos of other viewing angles, and if the extracted first sub-video includes the catkin video and the videos of other viewing angles, the playing sequence of the catkin video first and the videos of other viewing angles may be switched to play the first sub-videos.
In another implementation, a configuration interface may be provided for a user, the user configures a playing sequence of the sub-videos that the user desires to see, and when switching playing is performed, each first sub-video may be switched to be played according to the user configuration.
In an implementation manner of the embodiment of the present invention, it is expected that the main video and the sub video may implement complete synchronous playing, that is, the main video finishes playing the video segment in the first interaction interval and finishes playing the first sub video, so that the playing progress needs to be adjusted in real time.
S1041, identifying a position of a first video frame currently played by the main video in the first interaction interval.
S1042, obtain a first total number of video frames of the video segment in the first interaction interval and a second total number of video frames of the first sub-video in the first sub-video buffer.
S1043, calculating the proportion of the second sum of the video frames to the first sum of the video frames according to the first sum of the video frames and the second sum of the video frames.
S1044 is that the second video frame corresponding to the first video frame in the first sub-video and the playing speed of the first sub-video are determined according to the proportion of the second total number of the video frames to the first total number of the video frames and the position of the first video frame in the interaction interval.
S1045, continuing to play the main video from the first video frame, and playing the first sub video from the second video frame according to the playing speed.
The first total number of video frames of the video clip in the first interactive interval and the second total number of video frames of the first sub-video buffered in the first sub-video buffer may or may not be equal. If the two video frames are equal, when the same-screen playing is performed, if the main video is played to a certain video frame, the corresponding video frame is played when the first sub video is played, for example, the main video is played to the 3 rd frame, the first sub video also plays the 3 rd frame, and the playing rate of the main video is the same as the playing rate of the first sub video.
If the first total number of video frames of the video clip in the first interaction interval is not equal to the second total number of video frames of the first sub-video buffered in the first sub-video buffer area, the video clip and the first sub-video have a proportional relationship, for example, if the first video frame is the 3 rd frame, the first total number of video frames is 10 frames, and the second total number of video frames is 20 frames, according to the proportion of the second total number of video frames to the first total number, it can be determined that the second video frame corresponding to the first video frame is the 6 th frame in the first sub-video, and the remaining video clip is 7 frames, and the remaining first sub-video is 14 frames, the main video can be continuously played from the first video frame according to the original playing rate, and the first sub-video is played from the second video frame according to the playing rate 2 times of the main video.
In the embodiment of the present invention, the manner of synchronously playing the main video and the sub video may include two situations, namely, a user initiates an interactive request to drive synchronous playing and an electronic device automatically starts synchronous playing, and the two situations are respectively described below.
As shown in fig. 5, a flowchart of a video playing method for driving synchronous playing by a user initiating an interactive request according to an embodiment of the present invention may include the following steps.
S501, in the process of playing the main video, if the interactive request is obtained, detecting a first interactive interval to which a time point played by the main video when the interactive request is obtained belongs.
S502, according to the preset corresponding relation between the interaction interval and the sub-video buffer area, searching a first sub-video buffer area corresponding to the first interaction interval, wherein the sub-video buffer area is used for buffering the sub-video related to the video clip of the main video in the interaction interval.
