图2(a)为本发明公开的一种视频字幕的调节方法中，显示封装前的视频的显示屏示意图；
图2(b)为本发明公开的一种视频字幕的调节方法中，显示封装后的视频的显示屏示意图；
图3为本发明公开的一种视频字幕的调节装置的结构示意图。
具体实施方式
本发明实施例提供了一种视频字幕的调节方法及装置，以一定程度上解决传 统技术中，播放视频时字幕尺寸固定，不便于用户观看的问题。
为了使本领域的技术人员更好地理解本发明实施例中的技术方案，并使本发明实施例的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明实施例中技术方案作进一步详细的说明。
本发明第一示例性实施例中，公开一种视频字幕的调节方法。参见图1所示的工作流程示意图，所述视频字幕的调节方法包括以下步骤：
步骤S11、获取待播放的视频，并获取所述视频对应的字幕。
其中，获取视频对应的字幕时，可采用多种方法。其中一种方法中，可通过访问服务器，获取该视频的外挂字幕，将其作为所述视频对应的字幕。另外，若所述待播放的视频包含有内嵌字幕，可获取该视频的内嵌字幕，将其作为所述视频对应的字幕。
若所述待播放视频包含内嵌字幕，可采用裁剪方式获取该视频的内嵌字幕。视频中的内嵌字幕通常设置在视频比较靠边的位置，而很少位于视频中央，因此，在不影响画面观赏性的情况下，可以裁剪位于视频靠边位置的字幕，从而获取该视频的内嵌字幕。另外，还可对视频进行分解，获取该视频对应的各帧图像，然后通过图像处理技术，提取各帧图像中包含的字幕，从而获取该视频的内嵌字幕。
步骤S12、若要播放所述视频，获取字幕调节参数，并根据所述字幕调节参数，调节所述视频对应的字幕的尺寸，获取与所述字幕调节参数相对应的字幕。
在本发明中，字幕调节参数通常包括：终端设备的运行状态，和/或，终端设备的显示屏与用户之间的距离。当然，也可以采用其他形式的字幕调节参数，本发明对此不做限定。
适用本发明公开的视频字幕的调节方法的终端设备包含多种类型，因此，所采用的字幕调节参数不同。例如，若终端设备为设置有显示屏的跑步机，则所述字幕调节参数通常为终端设备的运行状态和终端设备的显示屏与用户之间的距离。其中，终端设备的运行状态通常为静止、走路和跑步等多种运行状态，在跑步的情况下，用户所需的字幕尺寸往往大于走路状态下显示的字幕尺寸，并且，往往跑步的速度越快，用户所需字幕尺寸越大，并且，终端设备上的显示屏与用户之间的距离越远，调节后字幕的尺寸越大，以便用户在运动过程中能看清字幕。
另外，若终端设备为设置有显示屏的冰箱，这种情况下，所述字幕调节参数 通常为终端设备的显示屏与用户之间的距离。显示屏与用户之间的距离越大，调节后的字幕的尺寸越大，从而使用户能看清字幕。
步骤S13、将调节后的字幕封装至所述视频，并播放封装有字幕的视频。
本发明的第一实施例公开一种视频字幕的调节方法。该方法中，获取待播放的视频和该视频对应的字幕，并在需要播放视频时，获取字幕调节参数，根据所述字幕调节参数，调节所述视频对应的字幕的尺寸，获取与所述字幕调节参数相对应的字幕，然后将调节后的字幕封装至所述视频，播放封装有字幕的视频。
通过本发明公开的方法，终端设备在播放视频时，能够根据字幕调节参数，调整字幕的尺寸，从而便于用户观看。
进一步的，本发明公开的视频字幕的调节方法还包括：
预先设置各种字幕调节参数与字幕尺寸之间的对应关系，并存储所述对应关系，以便在获取所述字幕调节参数后，根据所述对应关系调节所述字幕的尺寸。
本发明中，预先存储各种字幕调节参数与字幕尺寸之间的对应关系，这种情况下，获取到所述字幕调节参数后，根据所述对应关系即可确定所需的字幕尺寸，然后根据需求对字幕的尺寸进行调节即可。
若所述字幕调节参数包括终端设备的显示屏与用户之间的距离，本发明公开的视频字幕的调节方法中，则通过预先设置在所述终端设备的距离传感器，获取所述终端设备的显示屏与用户之间的距离。
其中，预先设置在终端设备的距离传感器可为多种形式，如红外测距传感器等，本发明对此不作限定。
另外，本发明的步骤S13中，公开了将调节后的字幕封装至视频的技术特征。若在封装前，所述视频中不包含内嵌内幕，所述将调节后的字幕封装至所述视频包括：
首先，分解所述视频，获取形成所述视频的各帧图像；然后，在所述各帧图像上的预设位置加载所述调节后的字幕。
其中，在所述各帧图像的预设位置加载所述调节后的字幕时，通常采用字幕压片技术。
另外，若在封装前，所述视频中包含内嵌字幕，所述将调节后的字幕封装至 所述视频包括：
首先，分解所述视频，获取形成所述视频的各帧图像；然后，在所述内嵌字幕所在的位置加载遮蔽背景，以便通过所述遮蔽背景遮挡所述内嵌字幕；最后，在所述遮蔽背景所在的位置加载所述调节后的字幕。
参见图2(a)所示的显示屏的示意图，该图的显示屏上显示的视频为封装前的视频，该视频的下方设置有内嵌字幕；本发明的方案中，为了避免封装调节后的字幕时，与该内嵌字幕产生干扰，因此设置遮蔽背景，以便遮挡所述内嵌字幕，并在所述遮蔽背景所在的位置加载所述调节后的字幕，其中，完成加载后，显示屏上显示的视频如图2(b)所示，由于该视频的内嵌字幕被遮蔽背景所遮挡，因此避免了对所述调节后的字幕的干扰。
相应的，本发明的第二实施例公开一种视频字幕的调节装置。参见图3所示的结构示意图，包括：获取模块100、调节模块200和封装模块300。
其中，所述获取模块100，用于获取待播放的视频，并获取所述视频对应的字幕；
所述调节模块200，用于若需要播放所述视频，获取字幕调节参数，并根据所述字幕调节参数，调节所述视频对应的字幕的尺寸，获取与所述字幕调节参数相对应的字幕；
所述封装模块300，用于将调节后的字幕封装至所述视频，并播放封装有字幕的视频。
本发明的第二实施例公开一种视频字幕的调节装置。该装置中，通过获取模块获取待播放的视频和该视频对应的字幕，并在需要播放视频时，通过调节模块获取字幕调节参数，并根据所述字幕调节参数，调节所述视频对应的字幕的尺寸，获取与所述字幕调节参数相对应的字幕，然后通过封装模块将调节后的字幕封装至所述视频，播放封装有字幕的视频。
通过本发明公开的装置，终端设备在播放视频时，能够调整字幕的尺寸，从而便于用户观看。
进一步的，本发明公开的所述视频字幕的调节装置还包括：
预存模块，用于预先设置各种字幕调节参数与字幕尺寸之间的对应关系，并存储所述对应关系，以便在获取所述字幕调节参数后，根据所述对应关系调节所 述字幕的尺寸。
本发明中，通过预存模块预先存储各种字幕调节参数与字幕尺寸之间的对应关系，这种情况下，获取到所述字幕调节参数后，所述调节模块根据所述对应关系即可确定所需的字幕尺寸，然后根据需求对字幕的尺寸进行调节即可。
在本发明中，所述字幕调节参数包括：终端设备的运行状态，和/或，终端设备的显示屏与用户之间的距离。当然，所述字幕调节参数还可以为其他形式，本发明对此不作限定。
进一步的，若所述字幕调节参数包括终端设备的显示屏与用户之间的距离，所述获取模块则通过预先设置在所述终端设备的距离传感器，获取所述终端设备的显示屏与用户之间的距离。
其中，预先设置在终端设备的距离传感器可为多种形式，如红外测距传感器等，本发明对此不作限定。
进一步的，若在封装前，所述视频中不包含内嵌字幕，所述封装模块包括：
第一分解单元，用于分解所述视频，获取形成所述视频的各帧图像；
第一加载单元，用于在所述各帧图像上的预设位置加载所述调节后的字幕。
进一步的，若在封装前，所述视频中包含内嵌字幕，所述封装模块包括：
第二分解单元，用于分解所述视频，获取形成所述视频的各帧图像；
背景设置单元，用于在所述内嵌字幕所在的位置加载遮蔽背景，以便通过所述遮蔽背景遮挡所述内嵌字幕；
第二加载单元，用于在所述遮蔽背景所在的位置加载所述调节后的字幕。
若在封装前，视频中包含内嵌字幕，为了避免封装调节后的字幕时，与内嵌字幕产生干扰，因此，通过背景设置单元加载遮蔽背景，以便遮挡所述内嵌字幕，并在所述遮蔽背景所在的位置加载所述调节后的字幕。
关于上述实施例中的装置，其中各个模块执行操作的具体方式已经在有关该方法的实施例中进行了详细描述，此处将不做详细阐述说明。
本发明实施例还提供一种终端设备，包括前述任一实施例所述的视频字幕的调节装置。
本发明实施例还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，该程序执行时可实现图1-图2(b)所示实施例提供的视频字幕的调节方法的各实现方式中的部分或全部步骤。
本领域的技术人员可以清楚地了解到本发明实施例中的技术可借助软件加必需的通用硬件平台的方式来实现。基于这样的理解，本发明实施例中的技术方案可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如只读存储器(英文：read-only memory，缩写：ROM)、随机存取存储器(英文：random access memory，缩写：RAM)、磁碟、光盘等，包括若干指令用以使得处理器执行本发明实施例或者实施例的某些部分所述的方法。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其它实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
