如图3所示，在一个实施例中，提供了一种视频分享方法，本实施例以该方法应用于上述图1中的基于社交网络的视频互动系统中的终端102a来举例说明。该方法具体包括步骤302至步骤308。
在步骤302中，获取视频片段。
具体地，移动终端102a可通过社交应用来获取视频片段。该社交应用可以是运行在移动终端102a上的独立应用程序，也可以是通过具有网页浏览功能的应用访问的网页应用或者轻应用。其中具有网页浏览功能的应用比如网页浏览器。
社交应用是指可为用户提供实时或者异步的基于社交网络的信息交互方式的应用。实时的信息交互方式比如即时通信，异步的信息交互方式比如分享内容。视频数据可以采用各种视频格式，包括：AVI、RMVB、3GP、MKV、MPEG、MPG、DAT以及MP4等视频格式中的至少一种。
在步骤304中，获取与视频片段的播放进度对应的备注触发位置。
具体地，终端102a可通过社交应用提供与该视频片段对应的备注触发位置输入框，获取在该备注触发位置输入框中输入的信息作为备注触发位置。
备注触发位置是用于触发展示相应的备注内容的位置。备注触发位置与视频片段的播放进度对应，是指该备注触发位置可以定位到视频片段的进度，具体可定位到特定的一个或多个视频帧。
该备注触发位置可以表示为自视频片段的播放起点开始到该备注触发位置的时间长度，也可以表示为自视频片段的播放起点开始到该备注触发位置的时间长度占视频片段的总播放时长的比例。
在一个实施例中，该备注触发位置还可以表示为视频片段按照预定时间长度所划分的播放时间区段的序号。具体可将视频片段按照预设时间长度划分为多个播放时间区段并赋予序号，比如每2秒划分出一个播放时间区段，从0开始顺序编号，若备注触发位置表示为2，则表示自视频片段的播放起始点开始的4秒至6秒的这一播放时间区段。
在步骤306中，获取备注触发位置所对应的备注内容。
备注内容是指用户生成的附加于视频片段的信息。在一个实施例中，备注内容包括可视元素和音频数据中的至少一种。其中可视元素包括图形标记、文本以及图标中的至少一种。可视元素是指可被人眼观测到的元素，图形标记是用图图形在视频数据的播放画面中所作出的标记。图形包括静态图标和动态图标，静态图标比如静态表情图标，动态图标比如表情动画图标。
具体地，终端102a可提供与备注触发位置对应的备注内容输入框，获取在该备注内容输入框中输入的文本作为该备注触发位置所对应的备注内容，或者获取在该备注内容输入框中输入的图标标识以获取该图标标识所对应的图标作为该备注触发位置所对应的备注内容。
在一个实施例中，终端102a可提供与备注触发位置对应的音频数据获取控件，检测到对该音频数据获取控件的操作时触发获取与该备注触发位置对应的音频数据。该音频数据可以是实时采集环境声音形成的，也可以是从文件目录中选取的。这样备注触发位置同时可以用来限制备注内容的显示时长。
在步骤308中，通过社交应用将视频片段、备注触发位置和备注内容分享至网络社交联系人的终端，以使该终端在播放视频片段至备注触发位置时在视频片段的播放画面上显示备注内容或以声音形式播放备注内容。
具体地，网络社交联系人是指与终端102a的用户具有基于社交网络的社交关系的用户，该社交关系比如可以是好友关系、同事关系、同学关系或者群组成员关系等。
终端102a通过社交应用，将视频片段以及与该视频片段对应的备注触发位置和备注内容上传到服务器104，使得该服务器104自动或者接收到终端102b的拉取请求时，将该视频片段以及与该视频频段对应的备注触发位置和备注内容发送到终端102b。终端102b是与终端102a的用户具有基于社交网络的社交关系的网络社交联系人的终端。
终端102b在接收到视频片段后，可自动或者在用户触发下在终端102b的内容分享页面中播放视频片段。终端102b在播放该视频片段的播放进度达到备注触发位置时，将该备注触发位置所对应的备注内容显示在视频片段的播放画面上，具体讲该备注触发位置所对应的可视元素的备注内容显示在视频片段的播放画面上。或者，终端102b在播放该视频片段的播放进度达到备注触发位置时，将该备注触发位置所对应的备注内容以声音形式进行播放，具体讲该备注触发位置所对应的音频数据的备注内容以声音形式进行播放。
上述视频分享方法，获取视频片段，并获取视频片段相应的备注触发位置和备注内容。这样当视频片段连同备注触发位置和备注内容被分享至网络社交联系人的终端时，该终端就可以在播放视频片段的播放进度达到该备注触发位置时，播放备注内容。这样用户可以通过备注的方式来传递附加于视频的信息，并且通过备注触发位置与视频的播放进度精确结合，进而与视频的具体内容相结合，可以更加有效地传递信息。
如图4所示，在一个实施例中，一种视频分享方法，包括步骤402至步骤414。
在步骤402中，获取视频片段。
在一个实施例中，步骤402包括：获取视频录制指令，根据视频录制指令采集图像以形成视频片段。具体地，移动终端102a可通过社交应用提供视频录制触发控件，检测到对该视频录制触发控件的操作时触发视频录制指令。该操作比如可以是点击、双击、长按以及沿预设轨迹滑动中的至少一种。移动终端102a可根据该视频录制指令，调用系统相机应用以通过图像采集器来采集图像形成视频片段。
举例说明，移动终端102a可通过社交应用展示如图5所示的内容分享页面，检测对该内容分享页面中的内容发布控件的操作以展示发布工具栏502，该发布工具栏502中展示有视频发布控件503。移动终端102a可检测到对该视频发布控件503的操作以进入图6所示的视频片段获取页面。移动终端102a可检测在该视频片段获取页面中的视频录制触发控件601的操作，触发视频录制指令，从而根据该视频录制指令采集图像已形成视频片段。移动终端102a可在视频数获取页面的预览区域602中实时展示采集的图像。
在一个实施例中，步骤402包括：获取视频片段选择指令，根据视频片段选择指令从本地文件目录中选择获得视频片段。具体地，移动终端102a可通过社交应用提供视频片段选择触发控件，如图6中在视频片段获取页面中的视频片段选择触发控件603，检测到对该视频片段选择触发控件的操作时触发视频片段选择指令。该操作比如可以是点击、双击、长按以及沿预设轨迹滑动中的至少一种。
在步骤404中，显示与视频片段的播放进度对应的播放时间轴。
具体地，参照图6，终端102a检测到视频片段获取页面中备注触发控件604的操作后，触发进入如图7所示的视频备注页面。播放时间轴与视频片段的播放进度对应，可用于控 制视频片段的播放进度。具体参照图7中视频备注页面中的播放时间轴701，该播放时间轴701具有时间刻度条701a和播放时间标记701b，该时间刻度条701a具有播放起始点刻度701a1和播放结束点刻度701a2，播放时间标记701b可沿时间刻度条701a移动，播放时间标记701b用于标记视频片段当前的播放进度。图7中播放时间轴为直线段，在其他实施例中播放时间轴还可以是曲线获取折线段，曲线或者折线段可以增加精度。播放时间轴也可以默认显示为直线段并在操作时变化为曲线段或者折线段。
在步骤406中，检测作用于播放时间轴的作用点。
具体地，当终端102a具有触控屏时，作用于播放时间轴的作用点可为作用于播放时间轴的触摸点。当终端102a的输入装置为鼠标时，终端102a可将检测到鼠标的光标对播放时间州的点击点作为作用于播放时间轴的作用点。终端102a也可以获取方向指令以移动作用点在播放时间轴701的位置，从而检测移动了位置的作用点。检测到作用点后播放时间标记701b显示在该作用点处，也可以根据播放时间标记701b的位置来确定该作用点的位置。
在步骤408中，根据作用点相对于播放时间轴的位置获取备注触发位置。
具体地，终端102a在检测到作用于播放时间轴701的作用点后，根据检测到的作用点相对于播放时间轴701的位置获取备注触发位置。
在一个实施例中，当播放时间轴701的时间刻度条701a为直线段时，终端102a可用该作用点相对于播放起始点刻度701a1的长度占播放起始点刻度701a1和播放结束点刻度701a2的总长度的比例，再乘以视频数据的总播放时长获得备注触发位置。
在一个实施例中，当播放时间轴701的时间刻度条701a为曲线段时，也可以用该作用点相对于播放起始点刻度701a1的曲线长度占播放起始点刻度701a1和播放结束点刻度701a2的曲线总长度的比例，再乘以视频数据的总播放时长获得备注触发位置。
上述步骤404到步骤408是上述步骤304的具体步骤。
在步骤410中，获取备注触发位置所对应的备注内容。
在一个实施例中，在步骤402之后，终端102a可以获取备注方式选择指令，从而根据备注方式选择指令选择相应的备注方式，根据选择的备注方式获取备注触发位置所对应的备注内容。其中备注方式包括图形标记备注方式、文本备注方式和录音备注方式。图形标记备注方式包括圈图备注方式，圈图备注方式是指利用封闭的图形在图像中做标记的备注方式，封闭的图形比如圆形、椭圆形以及多边形，多边形包括三角形、矩形以及五边形等等。圈图标记可选择鲜艳的颜色，比如红色，还可以根据播放画面的颜色自动配适圈图标记的颜色。
具体地，参照图7，终端102a在视频备注页面中提供备注方式选择控件702，检测对该备注方式选择控件702的操作以确定相应的备注方式。当备注方式为圈图备注方式时，终端102a检测对视频数据的播放画面的操作以生成圈图标记。
参照图8，当备注方式为文本备注方式时，终端102a检测对视频片段的播放画面的操作确定文本输入区域，从而获取在文本输入区域中输入的文本作为备注内容。参照图9，当备注方式为录音备注方式时，终端102a通过采集环境声音获得音频片段的备注内容。
在一个实施例中，终端102a可在视频备注页面中展示备注触发位置与备注内容的对应关系，还可以展示备注触发位置、备注方式和备注内容的对应关系。
在步骤412中，获取备注触发位置所对应的备注内容输入配置信息。
具体地，输入是指显示或者以声音形式播放，备注内容输出配置信息是用于配置如何显示备注内容或者如何以声音形式播放备注内容的配置信息。步骤412可在步骤410之前执行。
在一个实施例中，当备注内容包括可视元素时，备注内容输出配置信息包括可视元素在视频片段的播放画面中的显示位置。其中显示位置可以表示为在视频片段的播放画面的 坐标轴中的坐标，也可以表示为与视频片段的播放画面相邻两边的距离。当备注方式为圈图备注方式时，终端102a检测对视频片段的播放画面的操作而生成圈图标记时，获取该操作所在的位置作为圈图标记的显示位置。当备注方式为文本备注方式时，终端102a检测对视频片段的播放画面的操作确定文本输入区域，根据该操作所在的位置来确定文本的备注内容的显示位置，获取在文本输入区域中输入的文本作为备注内容。
在一个实施例中，备注内容输出配置信息还可以包括备注内容输出时间长度，该备注内容输出时间长度定义了备注内容从在播放画面上显示起或者自以声音形式播放起所经历的时间。当备注内容包括可视元素时，可视元素在播放画面中显示该备注内容输出时间长度的时间；当备注内容包括音频数据时，音频片段被播放该备注内容输出时间长度的时间。
在步骤414中，通过社交应用将视频片段、备注触发位置、备注内容以及备注内容输出配置信息分享至网络社交联系人的终端，以使该终端在播放视频片段至备注触发位置时，按照备注内容输出配置信息在视频片段的播放画面上显示备注内容或按照备注内容输出配置信息以声音形式播放备注内容。步骤414是上述步骤308的具体步骤。
具体地，终端102a通过社交应用，将视频片段以及与该视频片段对应的备注触发位置、备注内容以及备注内容输出配置信息上传到服务器104，使得该服务器104自动或者接收到终端102b的拉取请求时，将该视频片段以及与视频片段对应的备注触发位置、备注内容和备注内容输出配置信息发送到终端102b。终端102b是与终端102a的用户具有基于社交网络的社交关系的网络社交联系人的终端。
终端102b播放视频片段，并该该视频片段的播放画面上，按照备注内容输出配置信息所包括的可视元素的显示位置显示可视元素。并且按照备注内容输出配置信息所包括的备注内容输出时间长度控制备注内容所包括的可视元素的显示时长，或者控制备注内容所包括的音频数据的播放时长。
本实施例中，通过播放时间轴可以精确地获取到备注触发位置，从而可以实现对备注触发位置的精确控制。而通过备注内容输出配置信息可以控制备注内容的输出方式，使得备注内容的输出形式多样化。而且通过控制备注内容的显示位置，可以将备注内容与视频片段的内容深度结合，可以更有效地传递信息。
如图10所示，在一个实施例中，该视频分享方法还包括本地输出备注内容的步骤，具体包括步骤1002至步骤1008。
在步骤1002中，在社交应用的内容分享页面中播放视频片段。
具体地，用户在发布视频后，可在内容分享页面中查看分享的视频片段。终端102a可自动或者检测到对该视频片段的播放指令时，在社交应用的内容分享页面中播放视频片段。参照图11所述的内容分享页面，用户自己分享的内容显示在该内容分享页面中，当用户点击分享的视频片段后，终端102a开始播放该视频片段。
在步骤1004中，在播放视频片段的播放进度达到备注触发位置时，按照备注内容输出配置信息显示备注内容或者以声音形式播放备注内容。
具体地，终端102a按照备注内容输出配置信息所包括的可视元素的显示位置显示可视元素。并且按照备注内容输出配置信息所包括的备注内容输出时间长度控制备注内容所包括的可视元素的显示时长，或者控制备注内容所包括的音频数据的播放时长。
在步骤1006中，自显示备注内容或以声音形式播放备注内容起开始计时。
在步骤1008中，当计时达到备注内容输出配置信息所包括的备注内容输出时间长度时，停止显示备注内容或停止以声音形式能播放备注内容。
具体参照图12，图12中圈图标记的备注触发位置为自视频片段的播放起始点0起的6秒，则在6秒处按照圈图标记的显示位置来显示该圈图标记并开始计时，该圈图标记的备注内容输出时间长度为2秒。参照图13，当视频片段播放到7秒时，计时未达到2秒，则仍然显示圈图标记，并且显示7秒处的文本的备注内容，该文本的备注内容的备注内容输 出时间长度为2秒。参照图14，当视频片段播放到10秒时，圈图标记和文本已分别在8秒和9秒处停止显示，进而开始播放10秒处的备注内容为音频数据。
本实施例中，通过控制备注内容输出时间长度，可以控制各个备注内容的显示时间，从而协调各个备注内容的显示时间，避免备注内容的重叠显示影响到备注内容的显示效果或者播放效果。
下面用一个具体应用场景来说明上述视频分享方法的原理，参照图15，用户通过社交应用录制视频获得视频片段后，触发视频备注编辑操作，选择文本备注方式、圈图标记备注方式和录音备注方式中的至少一种来进行备注编辑操作，设置备注触发位置的备注内容，设置文本和圈图标记的显示位置，然后设置备注内容输出长度，完成设置，使得备注编辑操作生效。这样将视频分享给网络社交联系人的终端后，该终端就可以在播放视频片段至备注触发位置时在视频片段的播放画面上显示备注内容或以声音形式播放备注内容。
如图16所示，在一个实施例中，提供了一种视频播放方法，本实施例以该方法应用于上述图1中的移动终端102b来举例说明，具体包括步骤1602至步骤1606。

在一个实施例中，备注内容输出配置信息包括备注内容输出时间长度；视频播放装置1800还包括计时模块1804，用于自显示备注内容或以声音形式播放备注内容起开始计时，当计时达到备注内容输出时间长度时，停止显示备注内容或停止以声音形式播放备注内容。
在一个实施例中，备注内容包括可视元素和音频数据中的至少一种；当备注内容包括可视元素时，备注内容输出配置信息包括可视元素在视频片段的播放画面中的显示位置；可视元素包括图形标记、文本以及图标中的至少一种。
上述视频播放装置1800，网络社交联系人通过社交应用分享视频片段以及相应的备注触发位置和备注内容，在社交应用的内容分享页面中播放视频片段时，就可以在播放视频片段的播放进度达到该备注触发位置时，播放备注内容。这样网络社交联系人可以通过备注的方式来传递附加于视频的信息，并且通过备注触发位置与视频的播放进度精确结合，进而与视频的具体内容相结合，可以更加有效地传递信息。
本发明实施例还提供了一种视频片段的获取方法，该方法可以应用于图1中终端102中，请参阅图19，该方法可以包括步骤1901至步骤1904。
在步骤1901中，接收用户通过当前播放终端发送的视频截取指令。
其中，视频截取指令包括：截取开始时间点和截取结束时间点、用户在当前播放终端的播放界面中划定的视频截取区域以及用户选择的目标用途。
在本发明实施例中，用户在操作终端进行视频播放时，用户在观看到很感谢兴趣的视频时，用户可以操作终端上的截取视频按钮，从而触发终端执行视频片段的截取，例如，终端的触摸屏幕上显示一个截取视频按钮，当用户需要截取视频时，用户点击触摸屏幕上 的截取视频按钮，用户向终端发送一个视频截取指令，该视频截取指令包括用户需要的截取开始时间点，当用户不需要继续截取视频时，用户可以再次点击触摸屏幕上的截取视频按钮，用户可以再向终端发送一个视频截取指令，该视频截取指令包括用户需要的截取结束时间点。不限制的是，在本发明实施例中，用户直接可以确定需要截取的视频时长，则用户可以向终端发送一个视频截取指令，在该视频截取指令中包括截取开始时间点、截取结束时间点，终端可以确定从哪个时间点开始截取视频，以及该截取多长时间段的视频，通过截取开始时间点和截取结束时间点可以确定需要截取的视频时长。
另外，在本发明实施例中，当用户需要对当前播放终端的播放界面的部分画面区域进行截取，而不需要截取整个播放界面的视频画面时，用户设备可以在当前播放终端的播放界面中划定一个视频截取区域，那么在该视频截取区域以外的画面不做截取，此时用户设备也可以在视频截取指令中携带用户从播放界面中划定的视频截取区域。另外，用户通过视频截取指令还可以选择目标用途，以指示终端截取到视频片段会按照特定的目标用途来输出视频片段，例如用户将截取到的视频片段存档，或者存档后分享到QQ空间或者微信中，目标用途指明了用户需要输出的视频片段的特定用途，则本发明中视频截取得到的视频片段可以满足用户对上述目标用途的要求。
在本发明的一些实施例中，用户发送给终端的视频截取指令除了包括截取开始时间点、截取结束时间点、用户划定的视频截取区域和用户选择的目标用途之外，还可以包括用户需要指示终端的其它信息，例如，用户可以指示终端应该输出满足什么样视频参数要求的视频片段，即本发明中还可以进一步的对截取输出的视频片段按照用户要求的视频参数来输出相应的视频片段，从而可以满足用户对截取视频的更多要求。
具体的，在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标文件格式，即用户可以指示终端输出视频参数为目标文件格式的视频片段，其中，文件格式是指视频文件的文件本身的格式，例如可以是MP4、mkv等，目标文件格式指明了用户需要输出的特定文件格式，则本发明中视频截取得到的视频片段可以满足用户对上述目标文件格式的要求。
在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标分辨率，即用户可以指示终端输出视频参数为目标分辨率的视频片段，其中，分辨率是指视频文件的显示多少信息的设置，通常宽和高都以16倍数为步进单位，例如可以是即16×n(n＝1,2,3,....)，例如176×144，352×288等，目标分辨率指明了用户需要输出的特定分辨率，则本发明中视频截取得到的视频片段可以满足用户对上述目标分辨率的要求。
在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标视频格式，即用户可以指示终端输出视频参数为目标视频格式的视频片段，其中，视频格式是指视频文件的视频内容编码格式，例如可以是H264等，目标视频格式指明了用户需要输出的特定视频格式，则本发明中视频截取得到的视频片段可以满足用户对上述目标视频格式的要求。
在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标视频质量，即用户可以指示终端输出视频参数为目标视频质量的视频片段，其中，视频质量是指视频文件的视频传输等级要求，可以表征视频格式的复杂度，例如将视频质量划分为3个等级或者5等级，用户可以选择需要的目标视频质量为level III，目标视频质量指明了用户需要输出的特定视频质量等级，则本发明中视频截取得到的视频片段可以满足用户对上述目标视频质量的要求。需要说明的是，在本发明中视频质量还可以包括视频的其它参量，举例说明，视频质量可以用于表示视频的画面组(gop，group of picture)中关键帧之间的帧数量，视频质量可以用于表示视频的量化系数(qp，quantization parameter，可决定量化器的编码压缩率和图像精度，视频质量还可以用于表示视频的配置，例如包含baseline、main、high等主要设定指标。
在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标视频帧率，即用户可以指示终端输出视频参数为目标视频帧率的视频片段，其中，视频帧率是指视频文件的视频播放速率，表示每秒钟播放多少帧画面，例如视频帧率可以为30fps，用户可以选择需要的目标视频帧率为20fps，目标视频帧率指明了用户需要输出的特定视频帧率，则本发明中视频截取得到的视频片段可以满足用户对上述目标视频帧率的要求。
在本发明的一些实施例中，视频截取指令还可以具体包括用户选择的目标用途，即用户可以指示终端输出特定用途的视频片段，其中，目标用途是指视频文件被截取后的输出途径，例如可以是存档文件或者存档后分享，目标用途指明了用户需要输出的视频片段的特定用途，则本发明中视频截取得到的视频片段可以满足用户对上述目标用途的要求。
需要说明的是，前述内容中对本发明中终端接收到的视频截取指令包括的各种视频参数进行了详细说明，可以理解的是，本发明中视频截取指令中还可以包括上述的一种或者多种视频参数，具体需要用户选择哪种或者哪些种视频参数，具体可以结合应用场景来确定。
在步骤1902中，从播放时间为截取开始时间点开始，根据视频截取指令获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，直至播放时间为截取结束时间点为止，停止获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据。
在本发明实施例中，终端接收到包括截取开始时间点的视频截取指令之后，终端对终端的播放屏幕中当前播放的视频文件进行监测，获取到播放时间的进度，当播放时间达到截取开始时间点时，当前正在播放的播放时间即为截取开始时间点，从这个截取开始时间点起，终端实时获取到与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，并且本发明中从截取开始时间点开始终端需要一直获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，在没有接收到包含截取结束时间点的视频截取指令之前获取已解码视频数据不会停止。
其中，视频播放的过程就是将视频文件解码为原始数据再显示的过程，以截取开始时间点为标记，获取当前正在播放的视频文件，由于视频文件被软件解码器或者硬件解码器解码后成为已解码视频数据，根据解码前后的对应关系，可以由当前正在播放的视频文件对应找到相应的已解码视频数据，已解码视频数据通常是一种原始数据格式，由Y(亮度)、U(色度)、V(色度)三个分量组成，通常用于视频压缩领域，常用的是已解码视频数据可以是YUV420。例如，播放时间的时间轴显示正在播放的是4分20秒的视频文件，若终端接收到的视频截取指令中携带的截取开始时间点为4分22秒，则当前播放时间的时间轴转到4分22秒时，获取该时刻正在播放的视频文件对应的已解码视频数据，并且从4分22秒开始，终端需要一直获取当前正在播放的视频文件中与视频截取区域对应的已解码视频数据。
在本发明实施例中，终端在接收到包含截取开始时间点的视频截取指令之后，获取已解码视频数据的过程从截取开始时间点开始，在没有达到截取结束时间点的播放时间时，终端需要持续执行获取已解码视频数据的过程。当终端接收到包含截取结束时间点之后，终端监测播放时间的时间轴，当时间轴转到截取结束时间点时，终端不再获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据。可以理解的是，在本发明中终端获取到的已解码视频数据与播放终端中视频文件的播放顺序前后相同。
在本发明的一些实施例中，步骤1902根据视频截取指令获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，具体可以包括步骤A1至步骤A3。
在步骤A1中，计算视频截取区域与当前播放终端的播放界面之间的偏移位置。
在步骤A2中，根据计算出的偏移位置，确定视频截取区域与当前正在播放的视频文件中的视频图像的坐标映射关系。
在步骤A3中，根据坐标映射关系从当前播放终端的帧缓存中读取到与视频截取区域 对应的已解码视频数据。
其中，当前播放终端的显示屏幕上可以设置一个视频截取框，用户可以拖动视频截取框，并可以对视频截取框进行大小、长短、宽高的调整缩放，终端根据用户对视频截取框的调整情况获取到用户在播放界面中划定的视频截取区域，从而终端可以确定用户需要对播放界面中哪个部分或者全部的视频画面进行截取。请参阅如图20所示，为本发明实施例中视频截取区域的获取方式示意图，图20中，区域A为终端的全屏幕区域，区域B到区域C都是视频播放区域，区域B为播放界面，区域C为用户划定的视频截取区域。当然，区域C的位置和区域大小可以由用户拖拽视频截取框来调整。
确定用户划定的视频截取区域之后，执行步骤A1，终端计算视频截取区域与当前播放终端的播放界面之间的偏移位置，也就是说，终端的播放界面为矩形框，视频截取区域为矩形框，需要计算出视频截取区域的四个边角相对于当前播放终端的播放界面的四个角的偏移位置，从而就可以确定出视频截取区域与当前播放终端的播放界面之间的偏移位置。如图20所示，视频文件在显示屏幕上播放时，可以是全屏幕播放，如图20中区域A所示，也可以是非全屏幕区域，如图20中的区域B所示。也可以是区域B到区域A的任意一个区域。不管是在什么区域，用户都可以在视频播放区域内划出一个方形区域，用来作为想要截取的视频截取区域，根据像素位置关系可以计算出划定区域相对于视频播放区域的四个角的偏移位置。
获取到视频截取区域相对于视频播放界面的偏移位置之后，执行步骤A2，根据计算出的偏移位置，确定视频截取区域与当前正在播放的视频文件中的视频图像的坐标映射关系。即步骤A1中计算出的视频截取区域相对于视频播放界面的偏移位置，而视频播放界面与原始的视频图像之间还存在缩放关系，有可能视频播放界面与原始的视频图像相同，那么就是一比一的同等比例，也有可能用户在操作终端时对原始的视频图像进行放大或者缩小，显示为当前的视频播放界面，那么就需要将计算出的视频截取区域相对于视频播放界面的偏移位置进行重新映射，以得到视频截取区域与当前正在播放的视频文件中的视频图像的坐标映射关系。例如如图20所示，对于原始的视频图像坐标映射，因为区域B到区域C是不确定的，即视频播放区域的尺寸与原始视频图像的大小不一定相等，所以在完成上述的偏移位置之后，还需要计算出该偏移位置在原始的视频图像中的坐标映射关系。
在本发明的一些实施例中，步骤A3根据坐标映射关系从当前播放终端的帧缓存中读取到与视频截取区域对应的已解码视频数据。其中，当前播放终端中正在播放视频文件时，视频文件通过软件解码器或者硬件解码器已经将视频文件解码为已解码视频数据，终端从帧缓存中读取已解码视频数据，然后终端将读取到的已解码视频数据输出到显示屏幕上显示为播放界面，本发明中可以借助于帧缓存中保存的已解码视频数据，实时的获取从截取开始时间点开始，各个播放时间正在播放的视频文件对应的已解码视频数据，获取到正在播放的视频文件对应的已解码视频数据之后，根据坐标映射关系进行比例变换，获取到与视频截取区域对应的已解码视频数据，而在播放界面中视频截取区域以外的已解码视频数据不在获取的已解码视频范围之内。
需要说明的是，在本发明的一些实施例中，终端获取当前正在播放的视频文件中与视频截取区域对应的已解码视频数据还可以有其它的实现方式，例如首先获取到当前正在播放的视频文件对应的源文件，然后对源文件进行重新解码，可以生成已解码视频数据，根据坐标映射关系进行比例变换，获取到与视频截取区域对应的已解码视频数据，按照这样的方式也可以获取到已解码视频数据。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标分辨率，步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码之前，本发明提供的视频片段的截取方法还可以包括步骤B1至步骤B2。
在步骤B1中，判断获取到的已解码视频数据对应的视频文件中视频图像的原分辨率与 目标分辨率是否相同。
在步骤B2中，若原分辨率和目标分辨率不相同，对获取到的已解码视频数据对应的视频文件中视频图像的分辨率进行转换，得到包含目标分辨率的获取到的已解码视频数据。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标分辨率，则说明用户需要指定截取到的视频片段的分辨率，终端可以首先从视频文件的文件头信息中获取到视频图像的原分辨率，视频文件中视频图像的原分辨率为终端的显示屏幕中播放的视频文件被播放时显示的分辨率，若用户对视频文件中视频图像的原分辨率需要调整，终端的显示屏幕上可以显示分辨率调整菜单，由用户来指定截取到的视频片段的分辨率(即视频截取指令中携带的目标分辨率)，得到视频文件中视频图像的原分辨率之后，判断目标分辨率与原分辨率是否相同，若目标分辨率和原分辨率相同，则无需再进行分辨率的转换，若目标分辨率和原分辨率不相同，则需要对分辨率进行转换，具体的，可以调用第三方库(例如ffmpeg)来实现分辨率的转换，得到包含目标分辨率的获取到的已解码视频数据，则后续步骤1903中进行文件格式编码的就是此处描述的包含目标分辨率的获取到的已解码视频数据，即步骤1903中所述获取到的已解码视频数据具体为包含目标分辨率的获取到的已解码视频数据。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标分辨率，在前述执行了步骤A1至A3的应用场景下，步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码之前，本发明提供的视频片段的截取方法还可以包括步骤C1至步骤C3。
在步骤C1中，使用坐标映射关系和获取到的已解码视频数据对应的视频文件中视频图像的原分辨率计算出分辨率映射值。
在步骤C2中，判断分辨率映射值与目标分辨率是否相同。
在步骤C3中，若分辨率映射值与目标分辨率不相同，对获取到的已解码视频数据对应的视频文件中视频图像进行缩放处理，得到缩放后的获取到的已解码视频数据。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标分辨率，则说明用户需要指定截取到的视频片段的分辨率，终端可以首先从视频文件的文件头信息中获取到视频图像的原分辨率，视频文件中视频图像的原分辨率为终端的显示屏幕中播放的视频文件被播放时显示的分辨率，若用户对视频文件中视频图像的原分辨率需要调整，终端的显示屏幕上可以显示分辨率调整菜单，由用户来指定截取到的视频片段的分辨率(即视频截取指令中携带的目标分辨率)，得到视频文件中视频图像的原分辨率之后，结合前述执行步骤A1至A3的应用场景，用户对原始视频图像进行了调整，则可以按照上述步骤A1至A3来生成坐标映射关系，即视频截取区域与当前正在播放的视频文件中的视频图像的坐标映射关系，结合该坐标映射关系和原分辨率计算出分辨率映射值，然后判断目标分辨率与分辨率映射值是否相同，若目标分辨率和分辨率映射值相同，则无需对视频文件中视频图像进行缩放，若目标分辨率和分辨率映射值不相同，则需要对视频文件中视频图像进行缩放，具体的，可以调用第三方库(例如ffmpeg)来实现视频图像的缩放处理，得到缩放后的获取到的已解码视频数据，则后续步骤1903中进行文件格式编码的就是此处描述的缩放后的获取到的已解码视频数据，即步骤1903中所述获取到的已解码视频数据具体为缩放后的获取到的已解码视频数据。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标视频格式，步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码之前，本发明提供的视频片段的截取方法还可以包括步骤D1至步骤D2。
在步骤D1中，判断获取到的已解码视频数据对应的视频文件的原视频格式与目标视频格式是否相同。
在步骤D2中，若原视频格式和目标视频格式不相同，对获取到的已解码视频数据对 应的视频文件的视频格式进行转换，得到包含目标视频格式的获取到的已解码视频数据。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标视频格式，则说明用户需要指定截取到的视频片段的视频格式，终端可以首先从视频文件的文件头信息中获取到视频图像的原视频格式，视频文件中视频图像的原视频格式为终端的显示屏幕中播放的视频文件被播放时的视频格式，若用户对视频文件中视频图像的原视频格式需要调整，终端的显示屏幕上可以显示视频格式调整菜单，由用户来指定截取到的视频片段的视频格式(即视频截取指令中携带的目标视频格式)，得到视频文件中视频图像的原视频格式之后，判断目标视频格式与原视频格式是否相同，若目标视频格式和原视频格式相同，则无需再进行视频格式的转换，若目标视频格式和原视频格式不相同，则需要对视频格式进行转换，具体的，可以调用第三方库(例如ffmpeg)来实现视频格式的转换，得到包含目标视频格式的获取到的已解码视频数据，则后续步骤1903中进行文件格式编码的就是此处描述的包含目标视频格式的获取到的已解码视频数据，即步骤1903中所述获取到的已解码视频数据具体为包含目标视频格式的获取到的已解码视频数据。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标视频质量，步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码之前，本发明提供的视频片段的截取方法还可以包括步骤E1至步骤E2。
在步骤E1中，判断获取到的已解码视频数据对应的视频文件的原视频质量与目标视频质量是否相同。
在步骤E2中，若原视频质量和目标视频质量不相同，对获取到的已解码视频数据对应的视频文件的视频质量进行调整，得到包含目标视频质量的获取到的已解码视频数据。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标视频质量，则说明用户需要指定截取到的视频片段的视频质量，终端可以首先从视频文件的文件头信息中获取到视频图像的原视频质量，视频文件中视频图像的原视频质量为终端的显示屏幕中播放的视频文件被播放时显示的视频质量，若用户对视频文件中视频图像的原视频质量需要调整，终端的显示屏幕上可以显示视频质量调整菜单，由用户来指定截取到的视频片段的视频质量(即视频截取指令中携带的目标视频质量)，得到视频文件中视频图像的原视频质量之后，判断目标视频质量与原视频质量是否相同，若目标视频质量和原视频质量相同，则无需再进行视频质量的调整，例如，若视频质量具体表示视频的画面组中关键帧之间的帧数量，视频质量表示视频的量化系数，视频质量表示视频的配置，若目标视频质量和原视频质量相同，则上述视频参数都相同。若目标视频质量和原视频质量不相同，则需要对视频质量进行调整，具体的，可以调用第三方库(例如ffmpeg)来实现视频质量的转换，得到包含目标视频质量的获取到的已解码视频数据，则后续步骤103中进行文件格式编码的就是此处描述的包含目标视频质量的获取到的已解码视频数据，即步骤1903中所述获取到的已解码视频数据具体为包含目标视频质量的获取到的已解码视频数据。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标视频帧率，步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码之前，本发明提供的视频片段的截取方法还可以包括步骤F1至步骤F2。
在步骤F1中，判断获取到的已解码视频数据对应的视频文件的原视频帧率与目标视频帧率是否相同。
在步骤F2中，若原视频帧率和目标视频帧率不相同，对获取到的已解码视频数据对应的视频文件的视频帧率进行转换，得到包含目标视频帧率的获取到的已解码视频数据。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标视频帧率，则说明用户需要指定截取到的视频片段的视频帧率，终端可以首先从视频文件的文件头信息中获取到视频图像的原视频帧率，视频文件中视频图像的原视频帧率 为终端的显示屏幕中播放的视频文件被播放时显示的视频帧率，若用户对视频文件中视频图像的原视频帧率需要调整，终端的显示屏幕上可以显示视频帧率调整菜单，由用户来指定截取到的视频片段的视频帧率(即视频截取指令中携带的目标视频帧率)，得到视频文件中视频图像的原视频帧率之后，判断目标视频帧率与原视频帧率是否相同，若目标视频帧率和原视频帧率相同，则无需再进行视频帧率的转换，若目标视频帧率和原视频帧率不相同，则需要对视频帧率进行转换，具体的，可以调用第三方库(例如ffmpeg)来实现视频帧率的转换，得到包含目标视频帧率的获取到的已解码视频数据，则后续步骤1903中进行文件格式编码的就是此处描述的包含目标视频帧率的获取到的已解码视频数据，即步骤1903中所述获取到的已解码视频数据具体为包含目标视频帧率的获取到的已解码视频数据。
在步骤1903中，从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，生成从视频文件中截取出的视频片段。
在发明实施例中，前述步骤1902中获取到了从截取开始时间点直至截取结束时间点的多个已解码视频数据，当截取结束时间点到达时，终端停止获取已解码视频数据，则可以从截取结束时间点开始，终端已经获取到需要截取的视频文件对应的已解码视频数据，接下来对获取到的已解码视频数据进行打包封装，使通过步骤1902获取到的已解码视频数据被包装为文件的形式，即可以对获取到的已解码视频数据进行文件格式编码，从而可得到用户需要截取的视频片段，生成的视频片段是从终端的播放界面中播放的视频文件得到。
在本发明的一些实施例中，若视频截取指令还包括用户选择的目标文件格式，则步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，具体可以包括如下步骤：
使用文件合成器将获取到的已解码视频数据编码为满足目标文件格式的视频片段，并在视频片段中携带文件头信息，文件头信息包括：视频片段的属性信息。
其中，在步骤1902获取到已解码视频数据之后，若终端接收到的视频截取指令中还包括目标文件格式，则说明用户需要指定截取到的视频片段的文件格式，执行步骤1902获取到已解码视频数据之后，具体可以使用文件合成器将获取到的已解码视频数据编码为满足目标文件格式的视频片段，具体的，可以调用第三方库(例如ffmpeg)来实现文件格式的转换，得到满足目标文件格式的视频片段，使用文件合成器时会在生成的视频片段中携带文件头信息，文件头信息中携带的是视频片段的基本特征信息，例如文件头信息包括：视频片段的属性信息。
在步骤1904中，根据目标用途将视频片段输出。
在本发明实施例中，视频截取指令还包括用户选择的目标用途，则步骤1903从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，生成从视频文件中截取出的视频片段之后，还需要按照用户的选择来输出截取到的视频片段，从而终端可以解决用户对视频截取的需求。
也就是说，本发明中终端从视频文件中截取出视频片段之后，还可以按照用户的需要将视频片段输出到特定的目的用途中，例如用户将截取到的视频片段存档，或者存档后分享到个人博客或者微博中，目标用途指明了用户需要输出的视频片段的特定用途，则本发明中视频截取得到的视频片段可以满足用户对上述目标用途的要求。
通过以上实施例对本发明实施例的描述可知，首先接收视频截取指令，视频截取指令包括：截取开始时间点、截取结束时间点，然后从播放时间为截取开始时间点开始，根据视频截取指令获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，直至播放时间为截取结束时间点为止，停止获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，从截取结束时间点开始，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，生成从上述视频文件中截取出的视频片段。本发明中终端 中的播放界面开始播放视频文件后，当播放时间达到截取开始时间点之后，可以获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，在截取结束时间点还未达到之前，仍需要继续获取与当前正在播放的视频文件中与视频截取区域对应的已解码视频数据，根据视频截取指令可以获取到多个已解码视频数据，在截取结束时间点到达之后，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，从而可以生成从视频文件中截取出的视频片段。本发明中是通过获取正在播放的视频文件对应的已解码视频数据，然后再对已解码视频数据进行文件格式编码的方式得到需要截取的视频片段，而不是通过抓取多张的视频图像来组合得到视频片段，本发明中即使需要截取时间跨度大的视频片段，只需要由用户设置截取开始时间点和截取结束时间点即可，视频片段的截取处理效率也很高。
为便于更好的理解和实施本发明实施例的上述方案，下面举例相应的应用场景来进行具体说明。
以用户使用浏览器观看视频为例进行举例，用户遇到喜欢的视频画面，可以选择截取整个视频画面片段或者部分视频画面片段，制作为不含音频的视频片段，保存在本地或者分享给好友。请参阅如图21所示，为本发明中视频片段的截取流程示意图。
在步骤S1中，视频截取区域偏移位置计算
视频文件在终端的显示屏幕上播放时，可以是全屏幕播放，如图20中的区域A所示，可以是非全屏幕区域，如图20中的区域B所示。也可以是区域B到区域A的任意一个区域。不管是在什么区域，用户都可以在视频播放区域内划出一个方形区域，用来作为想要截取的视频截取区域，首先需要计算出划定区域相对于视频播放区域的四个角的偏移位置。
在步骤S2中，原始视频图像的坐标映射
因为区域B到区域C是不确定的，即视频播放区域的尺寸与原始的视频图像大小不一定相等，所以在完成上述的偏移位置之后，需要计算出该偏移位置在原始的视频图像中的坐标映射关系。
步骤S1和S2完成后，进行如下P1、P2、P3的菜单选择，终端的显示屏幕上需要给出一个菜单让用户选择，具体的，包括如下菜单：
P1，用途选择：确定截取到的视频片段是仅存档文件还是存档后分享。
P2，配置选择：分辨率、视频格式、视频质量，文件格式，视频帧率，视频截取时长(即截取开始时间点、截取结束时间点)。
P3，模式选择：确定需要截取出单个视频片段还是多个视频片段。
在步骤S3中，已解码视频数据的处理
当用户进行步骤S1划定区域操作时，默认从当前时间点开始处理。视频播放的过程，就是对视频文件解码为原始数据再显示的过程，通常原始数据是YUV420格式。从原始数据开始合成视频片段，可以省去重新解码源文件的环节，可以更节省终端的处理器资源，也可以节省终端的电量。
如图22所示，为本发明实施例提供的已解码视频数据的处理流程示意图，其中，该过程具体可以包括步骤m1至步骤m7。
在步骤m1中，从视频截取指令中获取用户选择的目标分辨率，目标视频格式和目标视频质量，目标文件格式，目标视频帧率，截取的视频长度。根据具体的配置情况不同，分为如下两个不同的处理过程，如Q1和Q2，接下来分别进行说明。
Q1、当满足以下条件：目标分辨率与原分辨率相同，目标视频帧率与原帧率相同，目标视频格式与原视频格式相同(即目标编码器与原解码器采用相同的压缩视频协议)，目标视频质量与原视频质量相同。满足这些条件时，可以选择Q1判决过程，根据视频截取指令对获取到的已解码视频数据进行文件格式编码，生成从视频文件中截取出的视频片段，此过程相当于拷贝模式。Q1过程中不需要解压缩视频文件，而仅仅将已解码视频数据重新 封装一个新的文件格式。
具体的，在Q1过程下的流程为：
在步骤m3中，根据目标文件格式，打开文件合成器，并生成文件头信息，在文件头信息包含了视频片段的一些基本特征，比如视频片段的属性，采用的视频编码格式。
在步骤m7中，调用文件合成器，将已编码视频数据按照规则进行文件格式编码，得到视频片段，这里的规则是指假若用户选择的目标文件格式为mp4文件，那最终编码得到的视频片段就应该是按照mp4文件对视频的组织方式生成视频片段。
Q2:不满足于Q1的任何一个条件，即至少满足如下一种条件：目标分辨率与原分辨率不相同，目标视频帧率与原帧率不相同，目标视频格式与原视频格式不相同(即目标编码器与原解码器采用不相同的压缩视频协议)，目标视频质量与原视频质量不相同，执行Q2判决过程。
具体的，在Q2过程下的流程为：
在步骤m2中，根据需要编码的视频格式，打开编码器。
在步骤m3中，根据文件格式，打开文件合成器，并生成文件头信息。
在步骤m4中,从当前播放过程的解码环节，取得已解码视频数据。
在步骤m5中，根据m1步骤中得到的信息，确定是否进行缩放处理，例如用户划定视频截取区域，将视频截取区域当前播放器范围相比较，得到一个比例关系，用这个比例关系结合原始分辨率，计算得到一个尺寸，如果这个尺寸与目标分辨率不相同，则需要进行缩放处理，使得输出视频片段的分辨率符合要求。如果不需要则无须缩放处理。
在步骤m6中，调用编码器，为已编码视频数据按照目标视频格式进行视频格式的编码。
在步骤m7中，调用文件合成器，将已编码视频数据按照目标文件格式进行编码，生成视频片段。
需要说明的是，本发明中对已编码视频数据处理的流程与视频文件的播放过程同步，如果是合成多个视频片段，则重复以上Q1或Q2过程。
在步骤S4中，视频片段的输出
