具体实施方式
在为多媒体文件设置封面图像时,智能终端通常会将多媒体文件中某一个视频帧的帧图像作为所述多媒体文件的封面图像。然而,采用上述方式设置封面图像时,仅能对单个多媒体文件进行封面图像设置,当需要针对多个多媒体文件(如,具有关联性的一系列多媒体文件)设置封面图像时,则需要逐个进行设置,同一操作需要反复执行,显然,这样会降低设置封面图像的操作效率,也降低了多媒体文件的展示效果,从而影响智能终端的使用性能。
为了解决不能同时设置多个多媒体文件的封面图像的问题,本公开实施例中,智能终 端确定待设置的多媒体文件集合以及获取目标封面图像后,按照所述待设置的多媒体文件集合包含的多媒体文件的数目,对所述目标封面图像进行分割,获得若干子图像,再将所述若干子图像分别设置为所述待设置的多媒体文件集合中各个多媒体文件的封面图像,从而使若干多媒体文件能呈现出更好的展示效果。
下面结合附图对本公开的实施方式做出进一步详细说明。
参阅图1所示,本公开实施例中,智能终端设置多媒体文件的封面图像的具体流程如下:
步骤100:智能终端响应于封面图像设置指令,确定待设置的多媒体文件集合。
具体实施例中,智能终端响应于用户的点击操作,可以打开指定的多媒体应用程序,登录服务器,并进入主页页面,在主页页面中,呈现了已拍摄的各个多媒体文件的预览图,智能终端可以获得所述各个多媒体文件的预览图,并呈现在屏幕上;智能终端可以响应于用户选取待设置的多媒体文件的指令,在各个多媒体文件中,选取需要设置封面图像的各个多媒体文件,形成待设置的多媒体文件集合。
例如,参阅图2所示,假设以一款拍摄多媒体文件的多媒体应用程序为例,以下称为应用程序(Application,APP)X,在响应于用户的点击操作,运行APP X并登录服务器之后,直接进入APP X的主页页面;如图2所示,在主页页面中,呈现了待设置封面图像的各个多媒体文件的预览图。
智能终端响应于封面图像设置指令(即用户点击“设置封面”按钮的操作),呈现获得的若干多媒体文件,具体的,智能终端可以在各个多媒体文件的预览图中呈现圆圈图案,以供用户选择。
本公开实施例中,在选择需要设置封面图像的各个多媒体文件时,包含但不限于以下两种方式:
方式1,响应于用户的点击操作,每响应一次,将点击位置对应的多媒体文件作为待设置的多媒体文件。
例如,参阅图3A所示,点击多媒体文件1的预览图中呈现的圆圈图案后,将所述多媒体文件1作为待设置的多媒体文件1,点击多媒体文件2的预览图中呈现的圆圈图案后,将所述多媒体文件2作为待设置的多媒体文件2,以此类推,获得待设置的多媒体文件3;
将获得的所述待设置的多媒体文件1、所述待设置的多媒体文件2、所述待设置的多媒体文件3,作为所述待设置的多媒体文件集合。
方式2,响应于用户点击操作,每响应一次,将点击位置对应的多媒体文件,以及与所述多媒体文件的位置关系满足指定条件的其他多媒体文件,作为待设置的多媒体文件。
例如,参阅图3B所示,点击多媒体文件1的预览图中呈现的圆圈图案后,将与所述多媒体文件1处于同一行的多媒体文件2,以及多媒体文件3作为所述待设置的多媒体文件集合。
当然,实际应用中,也可以将位于同一列的各个多媒体文件作为待设置的多媒体文件 集合,上述方式仅为举例,在此不再赘述。
步骤110:智能终端响应于选取指示,获取目标封面图像。
在一些实施例中,智能终端响应于用户的点击操作,进入目标封面图像备选区域,所述目标封面图像备选区域,可以是保存有各个图像文件的文件夹,也可以是保存有各个视频文件的文件夹。
在所述目标封面图像备选区域中,保存了已拍摄的各个多媒体文件(可以是图像文件、也可以是视频文件),智能终端可以响应于用户选取目标封面图像的指令,在所述各个多媒体文件中,选取需要设为封面图像的多媒体文件,形成所述目标封面图像。
在一些实施例中,在执行步骤110时,可以采用但不限于以下两种方式:
方式1,从保存有图像文件的文件夹中,响应于用户的点击操作,选取点击位置对应的图像作为所述待设置的多媒体文件集合的目标封面图像。
例如,参阅图4A所示,假设仍以APP X为例,智能终端运行APP X后,响应用户的指示,打开本地已保存的相册,并呈现已拍摄的各个图像文件的预览图,在用户点击所述相册中第一行中左起第1张图像的预览图内呈现的圆圈图案后,智能终端将所述相册中第一行中左起第1张图像作为所述待设置的多媒体文件集合的目标封面图像。
方式2,从保存有视频文件的文件夹中,响应于用户的点击操作,从点击位置对应的视频文件中,选取指定的视频帧对应的帧图像作为所述待设置的多媒体文件集合的目标封面图像。
例如,参阅图4B所示,假设仍以APP X为例,智能终端运行APP X后,响应于用户的指示,打开本地已保存有视频文件的文件夹,并呈现已拍摄的各个视频文件的预览图,在用户点击所述文件夹中的一个视频文件,并通过拖动所述视频文件的播放进度来选取所述视频文件中的某一视频帧后,智能终端将所述某一视频帧对应的帧图像(如,帧图像3)作为所述待设置的多媒体文件集合的目标封面图像。
步骤120:智能终端按照所述待设置的多媒体文件集合包含的多媒体文件的数目,对所述目标封面图像进行分割,获得若干子图像。
在一些实施例中,进一步地,智能终端可以响应于用户的操作指示,对所述目标封面图像进行相应的调整,具体的可以包含但不限于以下操作中的任意一种或任意组合:
对所述目标封面图像进行位置移动;
对所述目标封面图像进行放大或缩小;
对所述目标封面图像进行旋转;
对所述目标封面图像添加滤镜效果;
对所述目标封面图像添加文字效果;……
上述各类操作仅为举例,并不局限于此,在此不再赘述。
基于上述调整,智能终端按照所述待设置的多媒体文件集合中多媒体文件的数目,将所述目标封面图像进行分割,从而获得相应若干子图像。
例如,假设仍以APP X为例,智能终端运行APP X后,智能终端响应于用户选取了目标封面图像的操作,然后进入“封面编辑”页面;智能终端响应于用户点击,双指展开以及单指滑动的操作,对目标封面图像进行放大以及移位,经过上述调整后,智能终端按照所述待设置的多媒体文件集合包含的多媒体文件的数目,对所述目标封面图像进行分割。
例如,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为3,则智能终端将所述目标封面图像分割为3个部分,从而获得3个子图像,具体如图5A所示;
又例如,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为6,则智能终端将所述目标封面图像分割为6个部分,从而获得6个子图像,具体如图5B所示;
又例如,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为9,则智能终端将所述目标封面图像分割为9个部分,从而获得9个子图像,具体如图5C所示。
步骤130:智能终端将所述若干子图像分别设置为所述待设置的多媒体文件集合中各个多媒体文件的封面图像。
在一些实施例中,进一步地,智能终端可以响应用户点击操作,确定后续操作。
例如,假设仍以APP X为例,智能终端运行APP X,基于对所述目标封面图像进行的分割操作,智能终端响应于用户的点击操作进行后续操作,包括但不限于以下两种情况:
情况1,用户点击“取消”按钮,智能终端返回APP X的主页页面,具体如图6A所示;
情况2,用户点击“确定”按钮,智能终端为所述待设置的多媒体文件集合中各个多媒体文件依次设置所述封面图像,具体图6B所示。
本公开实施例中,智能终端响应于接收到“确定”指令,执行步骤130。
在一些实施例中,在执行步骤130时,智能终端将所述若干子图像分别设置为所述待设置的多媒体文件集合中各个多媒体文件的封面图像,可以采用但不限于以下两种方式:
方式1,智能终端按照所述待设置的多媒体文件集合包含的各个多媒体文件的已有顺序,将获得的若干子图像,依次设置为所述待设置的多媒体文件集合中各个多媒体文件的封面图像。
例如,参阅图7A所示,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为3,依次为多媒体文件1、多媒体文件2、多媒体文件3;以及假设所述智能终端将所述目标封面图像分割获得3个子图像,依次为子图像1、子图像2、子图像3。
假设仍以APP X为例,智能终端运行APP X后,所述智能终端将子图像1设置为所述多媒体文件1的封面图像,将子图像2设置为所述多媒体文件2的封面图像,以及将子图像3设置为所述多媒体文件3的封面图像。
在一些实施例中,待设置的多媒体文件集合包含的各个多媒体文件为对一个目标多媒体文件进行分割后获得的各个文件片段,以及所述各个多媒体文件的已有顺序为所述各个文件片段对应的时间先后顺序,那么,智能终端可以按照所述各个文件片段对应的时间先后顺序,将获得的若干子图像,依次设置为所述各个文件片段的封面图像,从而使得设置 后的各个封面图像,能够按照时间先后顺序拼接为对应所述目标多媒体文件的整体封面图像。
例如,参阅图7B所示,假设所述待设置的多媒体文件集合中各个多媒体文件为同一部电影进行分割后获得的各个电影片段,依次为电影片段1、电影片段2、电影片段3,分别为同一部电影的上、中、下三个部分,则所述各个多媒体文件的已有顺序即为所述各个电影片段对应的时间先后顺序,以及假设所述目标封面图像为与所述电影相关联的一张电影封面图像,那么,智能终端将所述目标封面图像分割获得3个子电影封面图像,依次为子电影封面图像1、子电影封面图像2、子电影封面图像3。
假设仍以APP X为例,智能终端运行APP X后,所述智能终端将子电影封面图像1设置为电影片段1的封面图像,将子电影封面图像2设置为电影片段2的封面图像,以及将子电影封面图像3设置电影片段3的封面图像。
这样,智能终端可以一次性为同一部电影的三个部分分别设置具有关联性的子电影封面图像,且在所述智能终端以及其他智能终端登录所述智能终端的主页页面后,在向各个智能终端展示各个电影片段的预览图界面时,可以在预览图界面中将各个电影片段对应的子电影封面图像拼接成一张完整的电影封面图像进行呈现,从而更好的反映电影的整体效果。
方式2,智能终端响应于用户的点击操作,对所述待设置的多媒体文件集合包含的各个多媒体文件进行顺序调整,再按照所述待设置的多媒体文件集合包含的各个多媒体文件的调整后顺序,将获得的若干子图像,依次设置为所述待设置的多媒体文件集合中各个多媒体文件的封面图像。
例如,参阅图7C所示,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为3,依次为多媒体文件1、多媒体文件2、多媒体文件3,以及假设所述智能终端将所述目标封面图像分割获得3子图像,依次为子图像1、子图像2、子图像3。
假设仍以APP X为例,智能终端运行APP X并登录服务器后,所述智能终端将多媒体文件1与多媒体文件2进行顺序对换,然后,所述智能终端将子图像1设置为所述多媒体文件2的封面图像,将子图像2设置为所述多媒体文件1的封面图像,以及将子图像3设置为所述多媒体文件3的封面图像。
这样,智能终端就可以通过对所述待设置的多媒体文件集合中包含的各个多媒体文件进行顺序调整,获得更好的基于所述各个多媒体文件的播放顺序,然后智能终端还可以一次性批量为所述各个多媒体文件分别设置各个子图像,从而,在所述智能终端以及其他智能终端登录所述智能终端的主页页面后,在向各个智能终端展示所述各个多媒体文件的预览图界面时,在所述预览图界面中将上述各个多媒体文件的封面图像拼接成一张完整的图像进行呈现,从而可以彰显视频内容以及视频文件的关联性。
所述智能终端基于上述两种方式设置的各个多媒体文件的封面图像,可以针对各个封面图像进一步设置有效期,令设置封面图像的操作存在时效性;在一些实施例中,参阅图 7D所示,在各个多媒体文件的封面图像的已设置时长达到设定阈值时,所述智能终端将所述多媒体文件集合中包含的各个多媒体文件的封面图像恢复为所述各个多媒体文件的原始封面图像。
例如,参阅图7D所示,假设所述待设置的多媒体文件集合中包含的多媒体文件数目为3,依次为多媒体文件1、多媒体文件2、多媒体文件3,以及假设所述智能终端将所述目标封面图像分割获得3子图像,依次为子图像1、子图像2、子图像3。
假设仍以APP X为例,智能终端运行APP X后,所述智能终端首先将子图像1设置为所述多媒体文件1的封面图像,将子图像2设置为所述多媒体文件2的封面图像,以及将子图像3设置为所述多媒体文件3的封面图像。
假设所述智能终端为所述待设置的多媒体文件集合中各个多媒体文件的自定义的封面图像设定了有效期,如,设定阈值为24小时,那么,在所述各个多媒体文件的封面图像的已设置时长达到24小时时,所述智能终端撤销对多媒体文件1设置的子图像1,恢复原始封面图像,撤销对多媒体文件2设置的子图像2,恢复原始封面图像,撤销对多媒体文件3设置的子图像3,恢复原始封面图像。
这样,所述智能终端还可以通过设定有效期的方式,在已设置时长达到设定阈值时,撤销对所述多个多媒体文件设置的自定义的封面图像,恢复原始封面图像,从而满足用户的多样需求,给予用户更好的视觉效果,以及增加趣味性和实用性。
