具体实施方式
实施本申请实施例的任一技术方案必不一定需要同时达到以上的所有优点。
为了使本领域的人员更好地理解本申请实施例中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请实施例一部分实施例，而不是全部的实施例。基于本申请实施例中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本申请实施例保护的范围。
下面结合本申请实施例附图进一步说明本申请实施例具体实现。
图1为本申请实施例一中视频处理方法的流程示意图；如图1所示，其包括如下步骤S101、以及步骤S102：
S101、提取视频序列中的多帧视频，并确定需要进行转场处理的相邻的两帧视频；
本实施例中，在步骤S101中在确定需要进行转场处理的相邻的两帧视频时，可以根据视频帧的帧号或者视频帧的时间戳确定需要进行转场处理的相邻的两帧视频。
本实施例中，视频序列又可以称之为视频流，视频帧的帧号也可以称之为流号。提取的不同帧视频，可以按照流号的大小进行缓存处理。
需要进行转场处理的相邻两帧视频可以由用户通过第三方应用程序提供的人机操作界面指定，也可以通过自动识别的方式进行确定。具体地，自动识别的方式比如具体通过计算相邻两帧视频的直方图差值确定，从中挑出直方图差值大于设定阈值对应的相邻两帧视频即为需要进行转场处理的对象，或者又称之为转场点。
S102、根据所述相邻的两帧视频的时间戳以及转场处理的转场时长，对所述相邻的两帧视频和转场视频进行合成以及进行转场字幕的添加。
本实施例中，步骤S1020中在对所述相邻的两帧视频和转场视频进行合成包括：将转场视频分摊到所述相邻的两帧视频中，所述转场视频在所述相邻的两帧视频中的分摊时长总和等于所述转场时长。
另外，本实施例中，步骤S102中进行转场字幕的添加包括：进行无情节字幕、有情节字幕和叠印字幕中至少一种转场字幕的添加。
具体地，比如相邻两个视频帧分别为视频帧A和视频帧B，视频帧A可以称之为出画面，而视频帧B可以称之为入画面，若设置的转场时长为6s，那么确定出视频帧A的最后3s和视频帧B的前3s，合起来得到6s。当然，此处仅为示例，也可以根据具体情况，灵活配置转场时长在前后两帧视频中的时间长短。另外，需要说明的是，转场处理之前视频帧A的最后3s的视频内容和视频帧B的前3s的视频内容可以预先截取或者删除掉，这样在进行转场的时候，直接把转场视频根据转场时长的分配插入到视频帧A和视频帧B之间，再进行合成，从而完成视频的合成。在视频合成时，可以将字幕内内容中字幕信息条列表中的每一条字幕信息条转换为字幕位图，对应地，在进行转场字幕的添加时，根据字幕位图的分辨率以及合成后的视频上像素的亮度特征和颜色通道特征，确定转场字幕合成后的视频上的添加位置。
图2为本申请实施例二中视频处理方法的流程示意图；如图2所示，其包括如下步 骤S201、步骤S202、步骤S203以及步骤S204：
S201、判断转场触发开关是否打开，若转场触发开关打开，则执行步骤S202；
本实施例中，通过配置的转场触发开关来控制转场处理的启动与否。转场触发开关可以为配置在引导用户进行转场处理的操作页面中，比如设置一控件按钮，通过检测该控件按钮是否有被操作的事件发生，从而确定是否转场触发开关是否打开。
S202、提取视频序列中的多帧视频；
与上述实施例不同的是，本实施例中增加了上述步骤S201，只有再通过步骤S201判断得知转场触发开关已打开时才会启动步骤S202中提取多帧视频的处理步骤，从而防止了误转场处理。
步骤S202中的提取多帧视频处理的过程可参照上述实施例一记载，不同的是，提取的多帧视频以二维数组的方式存储，二维数组的序号与视频帧的帧号一一对应。
S203、确定需要进行转场处理的相邻的两帧视频；
本实施例中，由于有二维数组的序号与视频帧的帧号一一对应，因此，参照上述实施例一中记载的手动或者自动方法确定出转场点之后，可以直接相邻两帧视频的帧号或者其对应的二维数据的序号即可。
S204、根据所述相邻的两帧视频的时间戳以及转场处理的转场时长，对所述相邻的两帧视频和转场视频进行合成以及进行转场字幕的添加；
本实施例中，在所述相邻的两帧视频和转场视频进行合成时，具体可以根据设定视频合成总帧数阈值判断是否合成结束，比如如果合成后的视频总帧数等于视频合成总帧数阈值时，在结束视频的合成处理。
本实施例中，在步骤S204中进行转场字幕的添加之前，可以首先对所述转场字幕进行解析以建立字幕信息条列表，再根据字幕信息条列表中字幕信息条的地址偏移量进行转场字幕的添加。
图3为本申请实施例三中视频处理方法的流程示意图；如图3所示，其包括如下步骤S301、步骤S302、步骤S303、步骤S304：
S301、提取视频序列中的多帧视频；
S302、确定需要进行转场处理的相邻的两帧视频；
本实施例中，上述步骤S301、S302类似上述实施例一或者二的相关记载。
S303、校正所述相邻的两帧视频的分辨率或者转场视频的分辨率，使得所述相邻的 两帧视频的分辨率和所述转场视频的分辨率一致；
本实施例中，预先设定有合成后的视频的分辨率，因此为了保证在合成的时候，就参考合成后的视频具有相同的分辨率，因此，本实施例中增加了对相邻的两帧视频的分辨率和所述转场视频的分辨率校正的处理。在实际的校正处理之前，可以首先检测相邻的两帧视频的分辨率和所述转场视频的分辨率，然后跟合成后的视频的分辨率进行大小比对，如三者不一致，则进行校正，如三者一致则不需要进行校正。
S304、根据所述相邻的两帧视频的时间戳以及转场处理的转场时长，对分辨率一致的所述相邻的两帧视频和转场视频进行合成以及进行转场字幕的添加。
本实施例中，在步骤S304中对所述相邻的两帧视频和转场视频进行合成时，可以根据转场配置参数对所述相邻的两帧视频和转场视频进行合成。所述转场配置参数包括视频流的缩放倍数、旋转角度、模糊样式、模糊程度中的任一一种或多种的组合。
可选地，在步骤S304中对所述相邻的两帧视频和转场视频进行合成时，具体可以根据转场特效方式，对所述相邻的两帧视频和转场视频进行合成。
具体地，所述转场特效包括淡出淡入、叠化、翻页、划像、圈出圈入、定格中的任一一种或多种的组合。
在另外一实施例中，上述步骤S304中可以包括上述步骤S303的校正过程，即校正作为步骤S304中的部分流程。

第一程序单元401，用于提取视频序列中的多帧视频，并确定需要进行转场处理的相邻的两帧视频；
第二程序单元402，用于根据所述相邻的两帧视频的时间戳以及转场处理的转场时长，对所述相邻的两帧视频和转场视频进行合成以及进行转场字幕的添加。
