图1为本发明实施例所提供的一种视频录制方法的流程示意图;
图2为本发明实施例所提供的另一种视频录制方法的流程示意图;
图3为本发明实施例提供的一种视频录制装置的结构示意图;
图4为本发明实施例提供的另一种视频录制装置的结构示意图的结构示意图;以及
图5为本发明电子设备一个实施例的结构示意图。
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的视频录制方法、装置和电子设备。
图1为本发明实施例所提供的一种视频录制方法的流程示意图,本实施例所提供的方法可以应用于直播场景下的视频录制,也可以应用于游戏场景下的视频录制,另外,还可以应用于视频聊天场景下的视频录制,本实施例中对于视频录制的应用场景不做限定。
如图1所示,视频录制方法包括以下步骤:
步骤101,在目标视频的播放过程中,对用户在编辑面板上进行的编辑过程进行截取得到多张第一图片,以及对所播放的目标视频分别进行多次图片转化得到多张第二图片。
其中,编辑面板包括用于进行内容编辑的绘画区域,以及用于选定编辑控件的选项区域。绘画区域为覆盖在所述目标视频上方的透明图层。
具体地,在目标视频播放过程中,当探测到开始录制的操作时,记录探测到开始录制的操作的系统时间点,作为起始时间点。从起始时间点开始,对目标视频进行图片转化,在每一次图片转化时,计算图片转化的时间点与起始时间点的差值,将该差值作为本次图片转化得到的第二图片的时间戳。同时,每一次图片转化得到第二图片时,对用户在所述编辑面板上所编辑的内容进行截取,得到对应的所述第一图片;所述第二图片和对应的所述第一图片具有相同的时间戳。
进一步,从该起始时间点开始,记录目标视频的音频流,将播放所述音频流中音频片段的时间点与起始时间点的差值,作为对应音频片段的时间戳。当探测到结束录制的操作时,停止进行图片转化,以及停止记录所述目标视频的音频流。
步骤102,对多张第一图片,分别与对应的第二图片进行叠加,得到多张帧图像。
具体地,具有相同时间戳的第一图片和第二图片具有对应关系,将第一图片分别与对应的第二图片进行叠加得到帧图像,帧图像的时间戳为叠加得到该帧图像的第一图片和第二图片的时间戳。
作为一种可能的实现方式,由于第二图片中包括非透明的用户所编辑的内容,将这些非透明的内容直接叠加在第一图片上,从而可以形成涂鸦的效果。
作为另一种可能的实现方式,可以对第一图片进行复制,从而得到多个非透明的内容,将多个非透明的内容直接叠加在第一图片上,从而可以形成印章的效果。
步骤103,根据对多张帧图像进行合成所得到的视频流,以及目标视频的音频流,生成录制的视频片段。
具体地,针对每一张帧图像,依据各帧图像的时间戳的顺序,在视频的时间轴上,对各帧图像进行合成,得到视频流。对视频流与音频流进行合成时,将音频流中各音频片段的时间戳,与视频流中各帧图像的时间戳进行时间轴同步,得到录制的视频片段。
在一种可能的应用场景中,本实施例所提供的方法可以由基于IOS操作平台的移动终端执行,IOS是苹果公司开发的移动操作系统,主要用于iPhone或iPad等移动设备,IOS操作平台提供一种方法,可以将指定可视化控件(UIView)以及所包含的子UIView生成为一张图片,在本实施例中,每一次图片转化时,移动终端采用这种方法,针对用户预先指定的UIView以及所包含的子UIView转化为一张图片,从而完成本次的图片转化,并得到本次图片转化的图片。
用户在指定UIView时,可以指定显示有该目标视频的屏幕内的全部UIView,也可以是部分UIView本实施例中对此不作限定。
本实施例中,通过在目标视频的播放过程中,对用户在编辑面板上进行的编辑过程进行截取得到多张第一图片,以及对所播放的目标视频分别进行多次图片转化得到多张第二图片之后,对多张第一图片,分别与对应的第二图片进行叠加,得到多张帧图像,进而根据对多张帧图像进行合成所得到的视频流,以及目标视频的音频流,生成录制的视频片段,满足了用户在视频录制过程中的个性化需求。
为了清楚说明上一实施例,本实施例提供了另一种视频录制方法,本实施例所提供的方法可以应用于直播的应用场景下,用于录制直播视频,图2为本发明实施例所提供的另一种视频录制方法的流程示意图,如图2所示,该视频录制方法,包括以下步骤:
步骤201,当探测到用户长按“录制屏幕按钮”时,记录用户长按“录制屏幕按钮”时的系统时间点,将该时间点作为起始时间点。
具体地,在本实施例中,长按“录制屏幕按钮”为开始录制的操作,当探测到用户长按“录制屏幕按钮”时,开始执行视频录制任务。视频录制任务视频录制任务开启定时器,从而以一定预设时间间隔,针对播放的目标视频进行多次图片转化、以及针对用户在编辑面板上进行的编辑过程进行多次图片截取和记录目标视频的音频流。由于视频生成时,需要根据系统时间点确定各帧图像的时间戳,因此,视频录制任务需要在开始执行视频录制任务时,首先记录系统当前时间点(startTime)作为起始时间点。
步骤202,创建用于保存录制的视频片段的文件。
具体地,视频录制任务在移动终端的文件系统中创建一个文件,该文件用于保存最终所录制的视频片段。一般来说,视频录制任务采用固定的名称对该文件进行命名,因此,作为一种可能的实现形式,移动终端的文件系统中不存在该名称的文件,则在文件系统中新建一个文件。作为另一种实现形式,移动终端的文件系统中已存在该名称的文件,则删除已存在的文件后,在文件系统中新建一个该名称的文件。在创建文件之后,开启目标视频的音频流输入源和视频流输入源,准备开始录制。
步骤203,在目标视频的播放窗口显示编辑面板。
具体地,编辑面板包括用于进行内容编辑的绘画区域,以及用于选定编辑控件的选项区域。其中,绘画区域为全屏覆盖在目标视频上方的透明图层;在选项区域内,显示有多个编辑控件,这些编辑控件用于选定绘制的属性,例如:编辑控件可以用于选择绘制的线条粗细、颜色等属性。从而用户在绘画区域内进行编辑时,可以依据预先选择的绘制属性,沿用户的触控轨迹进行绘制。
步骤204,在目标视频的播放过程中,对目标视频进行图片转化,得到本次图片转化得
到的第二图片,每一次图片转化得到第二图片时,对用户在所述编辑面板上所编辑的内容进行截取,得到对应的所述第一图片。
具体地,视频录制任务将屏幕内的指定的各个可视化控件转换成对应的控件图片,进而依据各可视化控件之间的相对位置,将各控件图片合成为一张图片转化得到的第二图片。本实施例中,每一次图片转化得到第二图片时,对用户在所述编辑面板上所编辑的内容进行截取,得到对应的第一图片。
在具体实现过程中,由于在目标视频的播放过程中,每一次图片转化得到第二图片时,对用户在所述编辑面板上所编辑的内容进行截取,因此,进行图片转化和内容截取的进程可以采用相同的计时器,每当达到计时周期时,执行图片转化和内容截取各一次,从而获得具有对应关系的第一图片和第二图片各一张。
需要说明的是,为了实现更好的录制效果,在对用户在所述编辑面板上所编辑的内容进行截取时,仅针对绘画区域内的内容进行截取,而不对选项区域进行截取。同理,在对目标视频进行图片转化时,一般不对“录制屏幕按钮”进行图片转化。
步骤205,计算图片转化的时间点与该起始时间点的差值,将差值作为本次图片转化得到的第二图片的时间戳,以及第二图片对应第一图片的时间戳。
具体地,视频录制任务记录本次图片转化的时间点,即当前时间点(currentTime),和起始时间点(startTime)的差值(Δvt=currentTime-startTime),将差值(Δvt)作为本次图片转化得到的第二图片的时间戳,以及作为第二图片对应第一图片的时间戳。
步骤206,根据时间戳,对第一图片,与对应的第二图片进行叠加,得到帧图像,将该帧图像以视频流的形式添加到录制的视频片段中。
具体地,视频录制任务将本次图片转化得到的第二图片,与具有相同时间戳的第一图片分别作为不同图层,进行叠加,得到帧图像,帧图像的时间戳为该第一图片和第二图片的时间戳。将帧图像与该帧图像的时间戳(Δvt)进行绑定,进而转换成操作系统特定数据类型,得到一帧图像,将该帧图像以视频流的形式添加到录制的视频片段中。
步骤207,记录播放器所播放的目标视频中主播的音频流,得到音频片段,将播放该音频流中音频片段的时间点与起始时间点的差值,作为对应音频片段的时间戳。
步骤208,将音频片段和对应的时间戳转换成音频流,依据音频流中音频片段的时间戳以及帧图像的时间戳,采用时间轴同步的方式,将音频片段插入到对应帧图像位置。
需要说明的是,在录制过程中,需要重复执行步骤204-步骤208,直至录制结束或暂停。
步骤209,当探测到用户执行结束录制的操作时,停止进行图片转化,以及停止记录所述目标视频的音频流,结束录制。
其中,本实施例中,结束录制的操作具体为松开“录制屏幕按钮”。
具体地,当探测到用户执行松开“录制屏幕按钮”的操作时,关闭定时器、关闭音频流输入源并结束视频录制任务。
步骤210,调用播放器预览录制的视频片段。
进一步,在预览之后,显示用于对该视频片段进行分享、保存或取消的控件,由用户从分享、保存或取消中选择所需的操作。
例如:用户可以在直播过程中,为主播画像,从而录制的视频片段中,同时包括了主播直播的过程,以及用户画像的过程。用户在预览该视频片段之后,可以将该视频片段分享给主播,或者其他用户,从而可以实现用户与主播,或者,用户之间的互动,提高了用户的体验。
本实施例中,通过在目标视频的播放过程中,对用户在编辑面板上进行的编辑过程进行截取得到多张第一图片,以及对所播放的目标视频分别进行多次图片转化得到多张第二图片之后,对多张第一图片,分别与对应的第二图片进行叠加,得到多张帧图像,进而根据对多张帧图像进行合成所得到的视频流,以及目标视频的音频流,生成录制的视频片段,满足了用户在视频录制过程中的个性化需求。
为了实现上述实施例,本发明还提出一种视频录制装置。
图3为本发明实施例提供的一种视频录制装置的结构示意图,如图3所示,该视频录制装置包括:播放模块31、叠加模块32和录制模块33。
播放模块31,用于在目标视频的播放过程中,对用户在编辑面板上进行的编辑过程进行截取得到多张第一图片,以及对所播放的目标视频分别进行多次图片转化得到多张第二图片。
其中,编辑面板包括用于进行内容编辑的绘画区域,以及用于选定编辑控件的选项区域。可选地,绘画区域为覆盖在所述目标视频上方的透明图层。

录制模块33,用于根据对所述多张帧图像进行合成所得到的视频流,以及所述目标视频的音频流,生成录制的视频片段。
