For example, video types include animation, entertainment, life, games, etc., and animation, entertainment, life, and games respectively correspond to first preview frames of different structures. In the embodiment of the present disclosure, by setting different first preview frames for different video types, the selection manner of the first preview frame is enriched.
在另一些实施例中，终端生成第一预览框架的实现方式包括：终端确定终端的终端类型匹配的第一预览框架，不同终端类型对应于不同结构的第一预览框架。在本公开实施例中，通过为不同的终端类型设置不同的第一预览框架，使得第一预览框架能够适配当前的终端，提高了第一预览框架的适配性。In some other embodiments, the terminal generating the first preview frame includes: the terminal determining the first preview frame matching the terminal type of the terminal, and different terminal types correspond to first preview frames of different structures. In the embodiment of the present disclosure, by setting different first preview frames for different terminal types, the first preview frame can be adapted to the current terminal, thereby improving the adaptability of the first preview frame.
在另一些实施例中，终端生成第一预览框架的实现方式包括：终端确定视频预览界面的显示比例匹配的第一预览框架，显示比例为视频预览界面占显示屏幕的比例，不同显示比例对应于不同结构的第一预览框架。In some other embodiments, the method for the terminal to generate the first preview frame includes: the terminal determines the first preview frame that matches the display ratio of the video preview interface, where the display ratio is the ratio of the video preview interface to the display screen, and different display ratios correspond to First preview frames of different structures.
其中，由于全屏状态下的视频预览界面较大，则设置包括较多数量的预览框的第一预览框架，使得第一预览框架能够展示更多的多媒体资源，从而能够通过多媒体资源对视频的全貌全面了解；而非全屏状态下的视频预览界面较小，则设置包括较小数量预览框的第一预览框架，使得界面更加整洁。Wherein, since the video preview interface in the full-screen state is relatively large, the first preview frame including a larger number of preview frames is set, so that the first preview frame can display more multimedia resources, so that the overall picture of the video can be viewed through the multimedia resources. Comprehensive understanding; the video preview interface in the non-full-screen state is small, and the first preview frame including a small number of preview frames is set to make the interface more tidy.
在另一些实施例中，终端基于多个多媒体资源的展示顺序，在视频预览界面轮流预览展示多个多媒体资源。其中，在预览展示的方式包括播放和展示缩略图的情况下，步骤305的实现方式包括：终端基于多个多媒体资源的展示顺序，在视频预览界面中轮流播放多个多媒体资源，展示未播放的多媒体资源的缩略图。其中，终端在播放一个多媒体资源的过程中，未播放的多媒体资源是非播放状态，终端在视频预览界面中，展示未播放的多媒体资源的缩略图。例如，3个多媒体资源分别为多媒体资源1、多媒体资源2和多媒体资源3，在播放多媒体资源1的过程中，终端在视频预览界面中展示未播放的多媒体资源的缩略图。In some other embodiments, the terminal previews and displays the multiple multimedia resources in turn on the video preview interface based on the presentation order of the multiple multimedia resources. Wherein, when the way of previewing and displaying includes playing and displaying thumbnail images, the implementation of step 305 includes: the terminal plays multiple multimedia resources in turn in the video preview interface based on the display sequence of multiple multimedia resources, and displays unplayed Thumbnails for multimedia assets. Wherein, when the terminal is playing a multimedia resource, the unplayed multimedia resource is in a non-playing state, and the terminal displays thumbnails of the unplayed multimedia resource in the video preview interface. For example, the three multimedia resources are respectively multimedia resource 1, multimedia resource 2 and multimedia resource 3. During the process of playing multimedia resource 1, the terminal displays thumbnails of unplayed multimedia resources on the video preview interface.
需要说明的一点是，终端基于多个多媒体资源的展示顺序，在视频预览界面中轮流播放多个多媒体资源的实现方式包括：终端基于多个多媒体资源的展示顺序，在视频预览界面中确定每个多媒体资源的展示位置，在每个多媒体资源的展示位置上，展示对应的多媒体资源；确定多个多媒体资源的播放顺序，基于播放顺序，轮流播放多个多媒体资源。It should be noted that, based on the display order of multiple multimedia resources, the realization method for the terminal to play multiple multimedia resources in turn in the video preview interface includes: based on the display order of multiple multimedia resources, the terminal determines each The display position of the multimedia resource is to display the corresponding multimedia resource at each display position of the multimedia resource; determine the playing sequence of the multiple multimedia resources, and play the multiple multimedia resources in turn based on the playing sequence.
其中，终端确定多个多媒体资源的播放顺序的实现方式包括：终端直接将展示顺序确定为播放顺序；或者，基于每个多媒体资源与当前登录账户的标签信息之间的匹配度，确定每个多媒体资源的播放顺序。其中，匹配度越高，多媒体资源在播放顺序中的位置越靠前，而匹配度越低，多媒体资源在播放顺序中的位置越靠后，从而实现优先播放用户感兴趣的多媒体资源。Wherein, the implementation method for the terminal to determine the playing order of multiple multimedia resources includes: the terminal directly determines the display order as the playing order; or, based on the matching degree between each multimedia resource and the label information of the current login account, determine the The playback order of the assets. Wherein, the higher the matching degree is, the higher the position of the multimedia resource is in the playing order, and the lower the matching degree is, the lower the position of the multimedia resource is in the playing order, so that the multimedia resource that the user is interested in is played preferentially.
在另一些实施例中，在预览展示的方式包括显示缩略图的情况下，步骤305的实现方式包括：终端基于多个多媒体资源的展示顺序，在视频预览界面中确定每个多媒体资源的展示位置，在每个多媒体资源的展示位置上，同时展示多个多媒体资源的缩略图。In some other embodiments, when the way of previewing and displaying includes displaying thumbnails, the implementation of step 305 includes: the terminal determines the display position of each multimedia resource in the video preview interface based on the sequence of displaying multiple multimedia resources , on the display position of each multimedia resource, simultaneously display the thumbnails of multiple multimedia resources.
其中，在多个多媒体资源的数量较多的情况下，由于视频预览界面的显示空间有限， 因此，将多个多媒体资源全部展示在视频预览界面中的方式会占据较大的显示空间，并且每个多媒体资源的显示区域很小，使得预览效果较差。因此，终端能够轮流预览展示多个多媒体资源。需要说明的一点是，轮流预览展示多个多媒体资源这一操作能够理解为快速展示，即操作也属于本公开实施例中的“同时展示”的范围。在本公开实施例中，通过轮流预览展示多个多媒体资源，节省了视频预览界面的显示资源。Among them, in the case of a large number of multiple multimedia resources, due to the limited display space of the video preview interface, the method of displaying all the multiple multimedia resources on the video preview interface will occupy a large display space, and each The display area of a multimedia resource is very small, making the preview effect poor. Therefore, the terminal can preview and display multiple multimedia resources in turn. It should be noted that the operation of previewing and displaying multiple multimedia resources in turn can be understood as quick display, that is, the operation also belongs to the scope of "simultaneous display" in the embodiments of the present disclosure. In the embodiment of the present disclosure, the display resources of the video preview interface are saved by previewing and displaying multiple multimedia resources in turn.
在一些实施例中，终端能够在视频预览界面中直接预览展示多个多媒体资源，或者，终端也能够在视频预览界面中预览展示添加音频后的多个多媒体资源。对于每个视频，终端在视频的多媒体资源中添加视频的音频信息，在视频预览界面中，预览展示添加音频信息的多媒体资源。其中，终端在视频预览界面中，预览展示多个多媒体资源的实现方式包括以下过程：终端获取每个多媒体资源对应的音频信息；将音频信息添加到多媒体资源中；在视频预览界面中，预览展示添加音频信息后的多媒体资源。In some embodiments, the terminal can directly preview and display multiple multimedia resources in the video preview interface, or the terminal can also preview and display multiple multimedia resources with audio added in the video preview interface. For each video, the terminal adds audio information of the video to the multimedia resource of the video, and previews and displays the multimedia resource with the added audio information on the video preview interface. Among them, in the video preview interface, the implementation of previewing and displaying multiple multimedia resources by the terminal includes the following process: the terminal obtains the audio information corresponding to each multimedia resource; adds the audio information to the multimedia resource; in the video preview interface, previews and displays Multimedia resources after adding audio information.
其中，在与视频对应的音频中，对于视频的每个时间点处的视频帧，均具有与视频帧对应的音频帧；则终端获取每个多媒体资源对应的音频信息的实现方式包括：终端基于多媒体资源中的视频帧对应的时间点，从与视频对应的音频中，确定时间点对应的音频帧；拼接同一多媒体资源对应的多个音频帧，得到多媒体资源对应的音频信息。Wherein, in the audio corresponding to the video, for the video frame at each time point of the video, there is an audio frame corresponding to the video frame; then the terminal obtains the audio information corresponding to each multimedia resource. The time point corresponding to the video frame in the multimedia resource is determined from the audio corresponding to the video, and the audio frame corresponding to the time point is determined; multiple audio frames corresponding to the same multimedia resource are spliced to obtain the audio information corresponding to the multimedia resource.
在一些实施例中，终端合成音频信息和多媒体资源，得到添加音频信息后的多媒体资源。In some embodiments, the terminal synthesizes the audio information and the multimedia resource to obtain the multimedia resource with the audio information added.
在一些实施例中，终端在视频预览界面中，预览展示多媒体资源的预览播放按钮；响应于预览播放按钮被触发，终端播放添加音频信息后的多媒体资源。In some embodiments, the terminal previews and displays a preview play button of the multimedia resource in the video preview interface; in response to the preview play button being triggered, the terminal plays the multimedia resource with audio information added.
在本公开实施例中，由于将视频对应的音频信息添加到了多媒体资源中，使得用户不仅能够预览视频的画面内容，还能够预览到视频对应的音频内容，进而使得用户能够结合多媒体资源中的画面内容和音频内容确定视频是否为感兴趣的视频，进而改善了视频预览的效果。In the embodiment of the present disclosure, since the audio information corresponding to the video is added to the multimedia resource, the user can not only preview the screen content of the video, but also preview the audio content corresponding to the video, thereby allowing the user to combine the screen content in the multimedia resource Content and audio content improve video preview by determining whether a video is of interest.
在一些实施例中，终端能够直接在视频的封面中同时预览展示多个多媒体资源，或者，终端也能够在视频预览界面的悬浮窗口中预览展示多个多媒体资源。例如，继续参见图4，在视频的封面上方展示悬浮窗口，在悬浮窗口中同时预览展示多个多媒体资源。在本公开实施例中，通过直接在视频预览界面中展示多个多媒体资源或者在悬浮窗口中展示多个多媒体资源，提供了不同的展示方式，进而提高了展示方式的可选择性。In some embodiments, the terminal can directly preview and display multiple multimedia resources on the cover of the video at the same time, or the terminal can also preview and display multiple multimedia resources in the floating window of the video preview interface. For example, continuing to refer to FIG. 4 , a floating window is displayed above the cover of the video, and multiple multimedia resources are simultaneously previewed and displayed in the floating window. In the embodiment of the present disclosure, by directly displaying multiple multimedia resources on the video preview interface or displaying multiple multimedia resources in a floating window, different display modes are provided, thereby improving the selectivity of the display modes.
需要说明的一点是，视频预览界面中包括的可预览的视频的数量为一个或者多个，在视频预览界面中包括的可预览的视频的数量为多个的情况下，以视频预览界面包括可预览的多个目标视频为例，多个目标视频包括视频，对于每个目标视频，终端均按照以上步骤302-305来生成目标视频的多个多媒体资源，并在视频预览界面中，同时预览展示目标视频的多个多媒体资源，由于一个目标视频会对应多个多媒体资源，则终端在视频预览界面中同时展示多个目标视频的多媒体资源。在一些实施例中，终端还能够对多个目标视频的多媒体资源进行布局，则终端确定多个目标视频在视频预览界面中的第二布局信息；确定第二布局信息匹配的第二预览框架；在第二预览框架中同时预览展示多个目标视频的多媒体资源。It should be noted that the number of previewable videos included in the video preview interface is one or more. Take the preview of multiple target videos as an example. The multiple target videos include videos. For each target video, the terminal generates multiple multimedia resources of the target video according to the above steps 302-305, and simultaneously previews and displays them in the video preview interface. There are multiple multimedia resources of the target video. Since one target video corresponds to multiple multimedia resources, the terminal simultaneously displays multiple multimedia resources of the target video on the video preview interface. In some embodiments, the terminal can also layout the multimedia resources of multiple target videos, then the terminal determines the second layout information of the multiple target videos in the video preview interface; determines the second preview frame matched by the second layout information; The multimedia resource displaying multiple target videos is simultaneously previewed in the second preview frame.
其中，第二预览框架为全局的预览框架。第二预览框架中包括多个第一预览框架，每个第一预览框架用于展示一个目标视频的多媒体资源。例如，第二布局信息用于表示视频预览界面的多个目标视频是并排在一行的，则第二预览框架包括的多个第一预览框架也是并排在一行的，从而使得第二预览框架与第二布局信息匹配，也即在预览展示多媒体资源的过程中，并不改变视频预览界面原有的布局，从而提高了界面展示的适配性。Wherein, the second preview frame is a global preview frame. The second preview frame includes a plurality of first preview frames, and each first preview frame is used to display a multimedia resource of a target video. For example, the second layout information is used to indicate that multiple target videos of the video preview interface are arranged side by side, and then the plurality of first preview frames included in the second preview frame are also arranged side by side, so that the second preview frame and the first preview frame are arranged side by side. Second, layout information matching, that is, in the process of previewing and displaying multimedia resources, the original layout of the video preview interface is not changed, thereby improving the adaptability of the interface display.
