具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种视频特效处理方法的流程图，如图1所示，视频特效处理方法用于终端设备中，例如：智能手机，计算机，平板设备，个人数字助理等，其具体可以是上述设备中的中央处理器或其他具有处理功能的部件来执行，包括以下步骤：
在步骤101中，接收视频特效处理指令；
通常用户在终端设备上播放视频时，为了增加趣味希望可以对视频增加一些特效，例如，视频内容是一只兔子飞奔在草地上，正常情况下视频只是显示兔子飞奔的画面，如果能够对兔子飞奔的部分进行慢放，就可以清晰地看到兔子飞奔过程中的每个微动作，这样用户观赏视频就可以获取到看电影大片的感觉；又例如，监控视频中大段的内容是画面呈静止状态，长时间没有变化，此时用户在观看视频时就希望可以对监控视频进行快放，这样就可以缩短观看视频的时间。本公开可以直接在视频播放的过程中对视频进行快放或慢放的特效处理。一般情况下，终端设备是按照正常的速率解码并播放视频的，但用户如果希望对视频进行快放或慢放的特效处理，可以在播放视频之前提前打开特效处理的功能，或者在视频播放的过程中以交互方式向终端设备输入特效处理的指令，这样的操作生成的视频特效处理指令可以触发终端设备对待处理视频进行特效处理。
在步骤102中，在播放待处理视频的过程中，根据所述视频特效处理指令对所述待处理视频进行快放或慢放特效处理。
通过视频特效处理指令的触发，终端设备一方面可以开启对待处理视频的快放或慢放特效处理，另一方面可以根据视频特效处理指令获取到对待处理视频进行特效处理的指示信息，例如，用户可以通过点击预设的特效处理按键，该按键可以是智能终端的触控屏上的虚拟按键，也可以是终端设备的实体按键，其可以包括专用的快放或慢放两个按键，也可以只有一个按键，通过单击或双击的不同点击方式产生快放或慢放的视频特效处理指令。这样终端设备可以根据视频特效处理指令对待处理视频进行与视频特效处理指令对应的特效处理。
本实施例的视频特效处理方法，通过接收的视频特效处理指令对播放中的待处理视频进行快放或慢放特效处理，实现视频播放和特效处理的同步进行，提高视频特效处理的效率，并增加视频播放的趣味性。
图2是根据一示例性实施例示出的一种视频特效处理方法的流程图，如图2所示，视频特效处理方法用于终端设备中，例如：智能手机，计算机，平板设备，个人数字助理等，其具体可以是上述设备中的中央处理器或其他具有处理功能的部件来执行，包括以下步骤：
在步骤201中，接收用户点击预设特效处理按键后产生的视频特效处理指令，所述预设特效处理按键用于提供开启对待处理视频进行慢放特效处理的触发；
本实施例以对待处理视频增加慢放特效为例，用户在播放视频之前就通过点击预设特效处理按键产生相应的视频特效处理指令，以触发终端设备在播放待处理视频的过程中进行慢放特效处理。预设特效处理按键可以是智能终端的触控屏上的虚拟按键，也可以是终端设备的实体按键，其可以包括专用的快放或慢放两个按键，也可以只有一个按键，通过单击或双击的不同点击方式产生快放或慢放的视频特效处理指令。用户在做出了点击慢放按键，或单击，或双击的操作后，终端设备根据该操作接收到对应于慢放特效处理的视频特效处理指令。图3为用户点击预设特效处理按键的示意图，如图3所示，终端设备播放视频的界面上设置了快放和慢放的启动按键，用户点击相应的按键后，在终端设备播放视频的过程中，就会采用本实施例的方法自动对待处理视频进行快放或慢放特效处理。
在步骤202中，根据所述视频特效处理指令对所述待处理视频进行运动量检测，确定所述待处理视频中需要进行所述慢放特效处理的视频帧；
终端设备可以根据上述视频特效处理指令自动对播放中的待处理视频进行运动量检测，通常针对视频中快速运动的画面，为了看清楚运动的过程或达到快跑慢放的反效果，就需要对该视频做慢放特效处理，而对于视频中几乎处于静止状态的画面，为了缩短观看时间或避免用户的不耐烦情绪，就需要对该视频做快放特效处理。基于此，终端设备可以采用动估计和运动补偿(Motion Estimate and Motion Compensation，简称：MEMC)技术对待处理视频中每个帧的运动量进行检测，即根据视频中各个帧的画面内容的运动变化的快慢，找出快速运动的帧，将其确定为需要进行慢放特效处理的视频帧。
终端设备可以根据所述视频特效处理指令对所述待处理视频进行运动量检测，获取所述待处理视频的每个视频帧上的所有预设区块的运动向量模值；确定每个所述视频帧上的第一区块，所述第一区块为运动向量模值大于预设运动向量阈值的预设区块；计算所述第一区块的数量与所述第一区块所属视频帧上的所有预设区块的数量的第一比值；判断所述第一比值是否大于第一预设占比阈值；若所述第一比值大于所述第一预设占比阈值，则确定所述第一区块所属视频帧为所述需要进行所述慢放特效处理的视频帧。
终端设备通过MEMC技术获取待处理视频的每个视频帧上的所有预设区块的运动向量模值，视频由多个连续的视频帧组成，每个视频帧又可以划分成多个预设区块，对应每个预设区块可以计算出一个运动向量模值，预先已经设置好了一个运动向量阈值，可以认为凡是大于该运动向量阈值的运动向量模值对应的预设区块就是画面内容为快速运动的第一区块，然后计算该第一区块在其所属视频帧中的数量占比，即第一区块的数量与第一区块所属视频帧上的所有预设区块的数量的第一比值，当第一比值大于第一预设占比阈值，表明第一区块所属的视频帧的画面处于快速运动状态，因此就需要对该视频帧进行慢放特效处理。
在步骤203中，根据预设插帧算法对所述视频帧进行插帧处理，以实现对所述待处理视频的慢放特效处理。
通过上述步骤，终端设备就可以根据MEMC技术通过对需要进行慢放特效处理的视频帧进行插帧处理，以实现对所述待处理视频的慢放特效处理，预设插帧算法可以包括插帧的倍数，以及插帧的数量与视频帧上运动速度的对应关系等。
本实施例的视频特效处理方法，终端设备通过根据视频特效处理指令自动对播放中的待处理视频进行运动量检测，以确定需要进行慢放特效处理的视频帧，并对该视频帧进行插帧处理，实现视频播放和慢放特效处理的同步进行，提高视频特效处理的效率，并增加视频播放的趣味性。
进一步的，与图2所示的方法实施例不同的是：当终端设备接收到的是用户点击快放按键，或单击，或双击的操作后产生的视频特效处理指令时，是对播放中的待处理视频进行快放特效处理，终端设备根据所述视频特效处理指令对所述待处理视频进行运动量检测，获取所述待处理视频的每个视频帧上的所有预设区块的运动向量模值；确定每个所述视频帧上的第二区块，所述第二区块为运动向量模值小于预设运动向量阈值的预设区块；计算所述第二区块的数量与所述第二区块所属视频帧上的所有预设区块的数量的第二比值；判断所述第二比值是否大于第二预设占比阈值；若所述第二比值大于所述第二预设占比阈值，则确定所述第二区块所属视频帧为所述需要进行所述快放特效处理的视频帧；根据预设抽帧算法对所述视频帧进行抽帧处理，以实现对所述待处理视频的快放特效处理。
如上所述，终端设备通过MEMC技术获取待处理视频的每个视频帧上的所有预设区块的运动向量模值，可以认为凡是小于预设运动向量阈值的运动向量模值对应的预设区块 就是画面内容为慢速运动的第二区块，然后计算该第二区块在其所属视频帧中的数量占比，即第二区块的数量与第二区块所属视频帧上的所有预设区块的数量的第二比值，当第二比值大于第二预设占比阈值，表明第二区块所属的视频帧的画面处于慢速运动状态，因此就需要对该视频帧进行快放特效处理。终端设备就可以根据MEMC技术通过对需要进行快放特效处理的视频帧进行抽帧处理，以实现对所述待处理视频的快放特效处理，预设抽帧算法可以包括抽帧的比例，以及抽帧的数量与视频帧上运动速度的对应关系等。
图4是根据一示例性实施例示出的一种视频特效处理方法的流程图，如图4所示，视频特效处理方法用于终端设备中，例如：智能手机，计算机，平板设备，个人数字助理等，其具体可以是上述设备中的中央处理器或其他具有处理功能的部件来执行，包括以下步骤：
在步骤301中，接收用户在终端设备上播放所述待处理视频的界面上进行滑动操作后产生的所述视频特效处理指令，所述滑动操作包括表示进行所述慢放特效处理的向左滑动操作；
本实施例以对待处理视频增加慢放特效为例，用户在播放视频的过程中，可以用手指在播放视频的界面上做出向左的滑动操作，该向左的滑动操作产生相应的视频特效处理指令，以触发终端设备在播放待处理视频的同时进行慢放特效处理。图5为用户在终端设备上播放待处理视频的界面上进行滑动操作的示意图，如图5所示，终端设备在播放视频的过程中，用户如果希望对视频增加快放或慢放的特效，就直接用手指在播放界面上向右或向左的滑动。
在步骤302中，根据所述视频特效处理指令和预设插帧算法，从接收到所述视频特效处理指令的时刻对应的视频帧开始对所述视频帧进行插帧处理，以实现对所述待处理视频的慢放特效处理。
通过视频播放过程中与用户的交互，终端设备可以获取到指示进行慢放特效处理的视频特效处理指令，此时终端设备就从接收到视频特效处理指令的时刻对应的视频帧开始进行上述插帧处理，这样就可以对所述视频帧开始往后的视频增加慢放特效。本实施例终端设备可以不用主动对待处理视频进行运动量检测，而是在接收到用户的交互操作产生的视频特效处理指令后，开始对待处理视频进行相应的特效处理。
本实施例的视频特效处理方法，终端设备通过根据在视频播放过程中接收到的视频特效处理指令对待处理视频进行慢放特效处理，实现视频播放和慢放特效处理的同步进行，提高视频特效处理的效率，并增加视频播放的趣味性。
进一步的，与图4所示的方法实施例不同的是：当终端设备接收到的是用户在终端设备上播放待处理视频的界面上进行向右滑动操作后产生的视频特效处理指令时，是对播放中的待处理视频进行快放特效处理，终端设备根据所述视频特效处理指令和预设抽帧算 法，从接收到所述视频特效处理指令的时刻对应的视频帧开始对所述视频帧进行抽帧处理，以实现对所述待处理视频的快放特效处理。
通过视频播放过程中与用户的交互，终端设备可以获取到指示进行快放特效处理的视频特效处理指令，此时终端设备就从接收到视频特效处理指令的时刻对应的视频帧开始进行上述抽帧处理，这样就可以对所述视频帧开始往后的视频增加快放特效。本实施例终端设备可以不用主动对待处理视频进行运动量检测，而是在接收到用户的交互操作产生的视频特效处理指令后，开始对待处理视频进行相应的特效处理。
图6是根据一示例性实施例示出的一种视频特效处理方法的流程图，如图6所示，视频特效处理方法用于终端设备中，例如：智能手机，计算机，平板设备，个人数字助理等，其具体可以是上述设备中的中央处理器或其他具有处理功能的部件来执行，包括以下步骤：
在步骤401中，接收用户在终端设备上播放所述待处理视频的界面上点击预设特效处理按键后产生的所述视频特效处理指令，所述预设特效处理按键用于提供开启对所述待处理视频进行所述慢放特效处理的触发；
本实施例与图3所示的方法实施例的区别在于，终端设备接收的视频特效处理指令，是用户在终端设备上播放所述待处理视频的界面上点击预设特效处理按键后产生的，此时正处于视频播放过程中，用户点击预设特效处理按键后触发终端设备开始对播放中的待处理视频进行特效处理。本实施例是以对待处理视频增加慢放特效为例。
在步骤402中，根据所述视频特效处理指令和预设插帧算法，从接收到所述视频特效处理指令的时刻对应的视频帧开始对所述视频帧进行插帧处理，以实现对所述待处理视频的慢放特效处理。
通过视频播放过程中与用户的交互，终端设备可以获取到指示进行慢放特效处理的视频特效处理指令，此时终端设备就从接收到视频特效处理指令的时刻对应的视频帧开始进行上述插帧处理，这样就可以对所述视频帧开始往后的视频增加慢放特效。本实施例终端设备可以不用主动对待处理视频进行运动量检测，而是在接收到用户的交互操作产生的视频特效处理指令后，开始对待处理视频进行相应的特效处理。
本实施例与图2所示方法实施例的区别在于，图2是在终端设备播放视频前，用户点击预设特效处理按键触发终端设备在播放待处理视频的过程中自动检测视频的运动量，并根据检测结果对待处理视频进行快放或慢放特效处理，而本实施例是在视频播放的过程中，用户点击预设特效处理按键触发终端设备从接收到视频特效处理指令的时刻对应的视频帧开始对待处理视频进行快放或慢放特效处理。即前者是终端设备主动进行特效处理，后者是通过与用户的交互触发终端设备进行特效处理。
本实施例的视频特效处理方法，终端设备通过根据在视频播放过程中接收到的视频特效处理指令对待处理视频进行慢放特效处理，实现视频播放和慢放特效处理的同步进行， 提高视频特效处理的效率，并增加视频播放的趣味性。
进一步的，与图6所示的方法实施例不同的是：用户点击的预设特效处理按键用于提供开启对所述待处理视频进行所述快放特效处理的触发，此时终端设备根据所述视频特效处理指令和预设抽帧算法，从接收到所述视频特效处理指令的时刻对应的视频帧开始对所述视频帧进行抽帧处理，以实现对所述待处理视频的快放特效处理。
通过视频播放过程中与用户的交互，终端设备可以获取到指示进行快放特效处理的视频特效处理指令，此时终端设备就从接收到视频特效处理指令的时刻对应的视频帧开始进行上述抽帧处理，这样就可以对所述视频帧开始往后的视频增加快放特效。本实施例终端设备可以不用主动对待处理视频进行运动量检测，而是在接收到用户的交互操作产生的视频特效处理指令后，开始对待处理视频进行相应的特效处理。
