具体实施方式
下面结合附图和实施例对本公开进行说明。此处所描述的实施例仅仅用于解释本公开，而非对本公开的限定。为了便于描述，附图中仅示出了与本公开相关的部分而非全部结构。
下述至少一个实施例中同时提供了可选特征和示例，实施例中记载的至少一个特征可进行组合，形成多个可选方案。
实施例一
图1是本公开实施例提供的一种视频获取方法的流程示意图，本实施例可适用于在用户分享视频的过程中基于已有的视频片段合成一个完整视频的情况，该方法可以由视频获取装置来执行，该装置可以采用软件和/或硬件的方式实现，并可配置于任何具有网络通信功能的终端上，例如智能手机、电脑和平板电脑(Portable Device，PAD)等。
如图1所示，本公开实施例中提供的视频获取方法可以包括S110至S120。
在S110中，获取用户通过视频选择界面选择的至少两个已有的视频片段，其中，视频选择界面是由视频拍摄界面或者详情界面切换后显示的界面。
视频交互应用不仅支持用户分享现场拍摄的视频，还支持用户分享基于已有的视频片段合成的视频。在用户启用终端上的视频交互应用后，可以触发其视频拍摄界面或者详情界面的特定标识，例如上传标识或者分享标识等，使得视频交互应用由当前界面切换至视频选择界面，即视频选择界面可以通过用户触发视频拍摄界面或者详情界面的特定标识而显示，其中，详情界面可以是音乐详情界面或者视频资源的详情界面等其他的信息详情界面。视频选择界面可以同步显示终端本地已有的视频片段，以方便用户选择。其中，如果视频选择界面是由音乐详情界面切换进入，则用户可以使用该音乐详情页的音频作为合成视频的背景音乐。
在选择过程中，用户可以触控视频选择界面上的视频缩略图位置进行视频预览，以决定是否选择该视频片段。在一实施例中，用户选择的已有的视频片段的时长大于或等于时长阈值，即时长阈值决定了用户可选择的有效视频片段。示例性的，时长阈值设置为3秒，当用户选择的已有的视频片段A的时长为2 秒时，可以弹出提示框(toast)，提示用户当前选择的已有的视频片段A无效，要重新进行选择。用户可选择的已有的视频片段的数量可以适应性设置，例如最大可以设置为12，本实施例对此不做具体限定。当用户选择的已有的视频片段的数量达到预设数量要求时，视频选择界面上的其他视频缩略图可以覆盖白色蒙层，并且不再支持用户选择。
在一实施例中，获取用户通过视频选择界面选择的至少两个已有的视频片段，包括：响应于用户在视频选择界面上触发的视频多选请求，获取所述用户选择的至少两个已有的视频片段。
示例性的，图2是本实施例提供的一种视频选择界面的示意图，如图2所示，视频选择界面上可以设置多选控件21，表示用户当前可以选择至少两个已有的视频片段。多选控件可以设置在界面边缘的任意位置，图2仅作为示例，将其设置在左下方。当检测到用户点击该多选控件时，视频交互应用响应于用户的视频多选请求，并实时获取用户选择的已有的视频片段。在一实施例中，图2中包括时间、电量等，示例性的，时间为中午12点之前(Ante Meridiem，AM)。
在S120中，基于预设视频时长，将至少两个已有的视频片段合成为小于或等于所述预设视频时长的目标视频。
在一实施例中，可以基于视频合成技术，按照用户自主设置的视频排列顺序或者视频交互应用预设的视频排列顺序，将至少两个已有的视频片段合成为一个时长小于或等于预设视频时长的完整视频。当至少两个已有的视频片段的总时长大于预设视频时长时，视频交互应用可以获取用户选择的视频起点和终点，通过视频剪裁，得到目标视频。在目标视频合成后，用户可以选择合适的视频格式将目标视频保存至本地特定的存储位置，也可以选择直接上传服务端进行视频分享。
其中，预设视频时长可适应性进行设置，例如15秒，本实施例不做具体限定。通过对合成的目标视频的时长进行限定，可以避免用户上传的视频过长，而导致视频交互应用与服务端的数据通信压力较大，进而影响用户分享视频的体验。
在一实施例中，基于预设视频时长，将至少两个已有的视频片段合成为小 于或等于预设视频时长的目标视频，包括：基于预设视频时长，按照所述至少两个已有的视频片段的选择顺序，将至少两个已有的视频片段合成为符合预设视频时长条件(即小于或等于所述预设视频时长)的目标视频。在此情况下，用户选择已有的视频片段的触控顺序决定了目标视频中包含的视频片段的排列顺序。继续如图2所示，用户每次选择一个已有的视频片段，其对应的视频缩略图左上角将会显示编号，作为用户选择已有的视频片段的记录信息，视频交互应用同时记录用户的选择顺序和选择的视频片段信息。
在一实施例中，基于预设视频时长，将至少两个已有的视频片段合成为小于或等于预设视频时长的目标视频，包括：
根据预设视频时长和视频编辑模式，将至少两个已有的视频片段合成为小于或等于预设视频时长的目标视频，其中，视频编辑模式包括视频整体编辑模式和/或分片段编辑模式。
用户可选择对已有的视频片段进行编辑与合成后再分享，也可以选择不进行编辑，而直接将合成的完整视频进行分享。在用户选择对已有的视频片段进行编辑的情况下，根据视频交互应用支持的视频编辑模式，用户可以选择的编辑模式包括以下三种：
1)用户对由至少两个已有的视频片段初步合成的完整视频进行整体性编辑，得到目标视频。
2)用户单独对每个已有的视频片段进行编辑，基于用户编辑之后的视频片段合成目标视频。
3)将用户对初步合成的完整视频的整体性编辑效果与单独对每个已有的视频片段的编辑效果进行叠加，得到每个已有的视频片段的最终编辑效果，进而合成目标视频。
在一实施例中，视频编辑模式中涉及的编辑操作包括下述至少一项：剪裁、播放速度编辑、分辨率编辑、播放画面旋转、视频删除和添加显示特效。通过为用户提供多种视频编辑操作，不仅表明了视频交互应用功能的丰富性，而且可以提高用户制作合成视频的乐趣，提高用户体验。在一实施例中，在视频编辑过程中，已有的视频片段的原始视频并不会发生改变，改变的只是存储在终端缓存中作为中间文件的视频数据。并且，如果用户基于视频整体编辑模式和 分片段编辑模式对视频进行多次编辑时，播放速度编辑和分辨率编辑可以始终以原始已有的视频片段为基础进行编辑，从而得到每个已有的视频片段的最终编辑效果。
在一实施例中，该方法还包括：
如果检测到放弃编辑请求，则由视频编辑界面切换至视频选择界面，其中，视频选择界面保持用户对至少两个已有的视频片段的选择状态。在视频编辑过程中，如果用户通过触控视频编辑界面的放弃控件，结束当前编辑操作，视频交互应用则由当前视频编辑界面切换至(返回)视频选择界面。继续如图2所示，当返回视频选择界面后，视频选择界面仍然保持用户对已有的视频片段的选择状态，即用户仍可以直接基于原始已有的视频片段合成完整视频，实现个性化视频的分享。
本公开实施例首先获取用户通过视频选择界面选择的至少两个已有的视频片段，然后基于预设视频时长，将至少两个已有的视频片段合成为符合预设视频时长的目标视频，即通过利用终端本地已有的视频片段合成完整视频，解决了相关技术中视频交互应用功能单一以及不能满足用户分享个性化视频的需求的问题，实现了在视频分享过程中基于多个已有的视频片段合成一个完整视频，扩展与丰富了视频交互应用的视频分享功能，使得视频分享模式不再局限于现拍现分享的模式；由于用户可以完全自主地制作待分享的合成视频，提高了用户的个性化视频分享体验，此外，还避免了相关技术中通过专业视频编辑软件对视频片段进行编辑的复杂操作，提高了视频编辑的便捷性。
实施例二
图3是本公开实施例提供的另一种视频获取方法的流程示意图，下面以视频编辑模式是视频整体编辑模式为例，对视频获取方法进行示例性说明。
如图3所示，本公开实施例中提供的视频获取方法可以包括S210至S230。
在S210中，获取用户通过视频选择界面选择的至少两个已有的视频片段，其中，视频选择界面是由视频拍摄界面或者详情界面切换后显示的界面。
S220、基于预设视频时长，将至少两个已有的视频片段合成为小于或等于预设视频时长的连续视频。
视频整体编辑模式是指在合成目标视频的过程中，以基于多个已有的视频片段初步合成的视频为编辑对象进行编辑。因此，本实施例中当获取用户选择的已有的视频片段后，基于预设的视频时长，初步合成一个连续视频。此时，该连续视频的时长可以和最终的目标视频的时长相同，也可以不相同。在一实施例中，在连续视频的合成过程中，可以按照一定的视频排列顺序，例如已有的视频片段的选择顺序，基于视频合成技术，将多个已有的视频片段合成为小于或等于预设视频时长的连续视频。
在S230中，获取用户在视频编辑界面对连续视频的编辑操作，并将编辑后的连续视频作为目标视频。
其中，视频编辑界面可以设置视频预览区，所述视频预览区设置为在视频编辑过程中进行效果预览。例如，连续视频合成之后，用户可以在视频预览区对其效果进行预览；如果检测到用户对连续视频的编辑操作，随着编辑操作的进行，用户也可以随时对编辑效果进行预览。在一实施例中，用户可以对连续视频进行的编辑操作包括剪裁、播放速度编辑、分辨率编辑、播放画面旋转、视频删除和添加显示特效中的至少一种操作。
通过剪裁，可以调整连续视频的时长，以得到符合时长要求的目标视频；通过播放速度编辑，可以调整连续视频的播放速度，使其快速播放或慢速播放；通过分辨率编辑，可以改变连续视频的播放画面的分辨率；通过视频删除，可以从视频编辑界面删除当前连续视频中包含的多个已有的视频片段，此时，还可以利用剩余已有的视频片段重新合成新的连续视频；通过播放画面旋转，可以改变视频的播放模式，例如由横屏播放调整为竖屏播放等；通过添加显示特效，例如一种或多种滤镜等，可以提高连续视频的画面展示效果。
示例性的，视频剪裁规则可以包括：当合成的连续视频的总时长小于或等于预设的目标视频的时长时，可以根据用户需求确定是否剪裁，但此时的连续视频均填充满整个剪裁区；当连续视频的总时长大于预设的目标视频的时长时，可以剪裁出等于预设的目标视频时长的视频长度，或者根据用户的设定时长进行裁剪；此外，当剪裁的视频长度达到目标视频时长要求的最大值或者最小值时，可以设置提示操作，例如震动，以免用户剪裁操作出错。剪裁结束后，可以对视频进行预览播放。
图4作为示例，示出了本实施例中的一种设置有视频预览区的视频编辑界面的示意图。如图4所示，视频编辑界面可以由视频选择界面直接切换进入，该视频编辑界面包括视频预览区41、视频裁剪区42和视频片段区43。其中，视频预览区41设置为在视频编辑过程中预览连续视频；视频裁剪区42左右两侧的把手可以随着用户的拖动而移动，以实现调整预览的连续视频时长；视频裁剪区42内的指针随着预览视频的播放而移动；视频片段区43展示用户选择的至少两个已有的视频片段，通过在该区域内的左右滑动，可以查看用户选择的所有视频片段。视频编辑界面的边缘位置，或者视频预览区41和视频裁剪区42之间的空隙，均可以用于设置编辑控件，例如剪裁控件、播放速度编辑控件、分辨率编辑控件等。
当视频交互应用检测到用户的编辑操作结束后，便将编辑之后的连续视频作为目标视频，用户可以在视频预览区进行效果预览。当检测到用户在视频编辑界面触发的编辑确定请求，即用户对所有的编辑效果进行保留，则将目标视频以视频格式保存至终端特定的存储位置；同时，如果检测到用户的视频分享请求，则将目标视频分享至服务端。
本公开实施例首先获取用户通过视频选择界面选择的至少两个已有的视频片段，然后基于预设视频时长，将至少两个已有的视频片段合成为小于或等于预设视频时长的连续视频，最后获取用户在视频编辑界面对连续视频的编辑操作，并将用户编辑后的连续视频作为目标视频，解决了相关技术中视频交互应用功能单一以及不能满足用户分享个性化视频的需求的问题，实现了在视频分享过程中基于多个已有的视频片段合成一个完整视频，扩展与丰富了视频交互应用的视频分享功能以及视频编辑功能，使得视频分享模式不再局限于现拍现分享的模式；由于用户可以完全自主地制作待分享的合成视频，提高了用户的个性化视频分享体验。
实施例三
图5是本公开实施例提供的又一种视频获取方法的流程示意图，下面以视频编辑模式是分片段编辑模式为例，对视频获取方法进行示例性说明。
如图5所示，本公开实施例中提供的视频获取方法可以包括S310至S330。
在S310中，获取用户通过视频选择界面选择的至少两个已有的视频片段， 其中，视频选择界面是由视频拍摄界面或者详情界面切换后显示的界面。
在S320中，获取用户在视频编辑界面每次对至少两个已有的视频片段中的一个已有的视频片段的编辑操作。
本实施例中分片段编辑模式是指在合成目标视频片段的过程中，以单个已有的视频片段为编辑对象进行编辑。在一实施例中，用户编辑操作的次数小于或等于获取的已有的视频片段的数量。在一实施例中，用户可以对每个已有的视频片段进行的编辑操作包括剪裁、播放速度编辑、分辨率编辑、播放画面旋转、视频删除和添加显示特效中的至少一种操作。其中，通过剪裁，可以调整已有的视频片段的时长，得到用户感兴趣的视频段；通过播放速度编辑，可以调整视频片段的播放速度，使其快速播放或慢速播放；通过分辨率编辑，可以改变视频片段的播放画面的分辨率，最终得到分辨率统一的多个已有的视频片段，保证合成的目标视频的画面展示效果；通过视频删除，可以从用户选择的多个已有的视频片段中完整去除某一个已有的视频片段，而无需从当前视频编辑界面重新返回视频选择界面；通过添加显示特效，例如一种或多种滤镜等，可以提高视频画面展示效果。
视频编辑界面可以设置视频预览区，该视频预览区设置为用户对单个已有的视频片段的编辑效果进行预览。图6作为示例，示出了本实施例中的另一种设置有视频预览区的视频编辑界面的示意图。如图6所示，视频编辑界面包括视频预览区61、视频裁剪区62和视频片段区63。其中，视频预览区61设置为在视频编辑过程中预览当前视频片段的效果；视频裁剪区62左右两侧的把手可以随着用户的拖动而移动，以实现调整当前预览的视频片段的时长；视频裁剪区62内的指针随着预览视频的播放而移动；视频片段区63展示用户当前编辑的视频片段。视频编辑界面的边缘位置，或者视频预览区61和视频裁剪区62之间的空隙，均可以用于设置编辑控件，例如剪裁控件、播放速度编辑控件、分辨率编辑控件等。
图6所示的对于单个已有的视频片段的编辑界面可以由视频选择界面直接切换进入，也可以由图4所示的视频编辑界面切换进入。示例性的，用户可以通过在如图4所示的视频编辑界面中，触控分片段编辑控件(图4中未示出)，视频交互应用响应于用户的切换请求，切换至如图6所示的针对单个已有的视 频片段的编辑界面。
在S330中，基于预设视频时长，将用户编辑后的至少两个已有的视频片段合成为小于或等于预设视频时长的目标视频。
当视频交互应用检测到用户的编辑操作结束后，按照一定的视频排列顺序，例如用户选择已有的视频片段的选顺序，将编辑之后的多个已有的视频片段合成为小于或等于预设视频时长的目标视频，用户可以在视频预览区进行效果预览。当检测到用户在视频编辑界面触发的编辑确定请求，即用户对所有的编辑效果进行保留，则将目标视频以视频格式保存至终端特定的存储位置；同时，如果检测到用户的视频分享请求，则将目标视频分享至服务端。
在一实施例中，基于编辑之后的已有的视频片段合成目标视频的过程中，如果用户进行裁剪编辑，此时的裁剪规则可包括：首先确定目标视频的首帧画面和末帧画面，然后根据目标视频的要求时长进行裁剪；或者，只确定目标视频的首帧画面，结合目标视频的要求时长进行裁剪。裁剪规则可以根据用户对目标视频的要求而定。
本公开实施例首先获取用户通过视频选择界面选择的至少两个已有的视频片段，然后获取用户在视频编辑界面每次对至少两个已有的视频片段中的一个已有的视频片段的编辑操作，最后基于预设视频时长，将用户编辑后的至少两个已有的视频片段合成为小于或等于预设视频时长的目标视频，解决了相关技术中视频交互应用功能单一以及不能满足用户分享个性化视频的需求的问题，实现了在视频分享过程中基于多个已有的视频片段合成一个完整视频，扩展与丰富了视频交互应用的视频分享功能以及视频编辑功能，使得视频分享模式不再局限于现拍现分享的模式；由于用户可以完全自主地制作待分享的合成视频，提高了用户的个性化视频分享体验。

上述计算机可读介质可以是上述终端中所包含的；也可以是单独存在，而未装配入该终端中。
上述计算机可读介质承载有一个或者多个程序，当上述一个或者多个程序被该终端执行时，使得该终端执行本公开任意实施例所述的方法，例如：获取用户通过视频选择界面选择的至少两个已有的视频片段，其中，所述视频选择界面是由视频拍摄界面或者详情界面切换后显示的界面；将所述至少两个已有的视频片段合成为小于或等于预设视频时长的目标视频。
可以以一种或多种程序设计语言或其组合来编写用于执行本公开的操作的计算机程序代码，上述程序设计语言包括面向对象的程序设计语言-诸如Java、Smalltalk、C++，还包括常规的过程式程序设计语言-诸如“C”语言或类似的程序设计语言。程序代码可以完全地在用户计算机上执行、部分地在用户计算机上执行、作为一个独立的软件包执行、部分在用户计算机上部分在远程计算机上执行、或者完全在远程计算机或服务器上执行。在涉及远程计算机的情形中，远程计算机可以通过任意种类的网络——包括局域网(Local Area Network，LAN)或广域网(Wide Area Network，WAN)-连接到用户计算机，或者，可以连接到外部计算机(例如利用因特网服务提供商来通过因特网连接)。
附图中的流程图和框图，图示了按照本公开一种或多种实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段、或代码的一部分，该模块、程序段、或代码的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。也应当注意，在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个接连地表示的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。在一实施例中，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或操作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。
描述于本公开实施例中所涉及到的模块或单元可以通过软件的方式实现，也可以通过硬件的方式来实现。其中，模块或单元的名称并不构成对该模块或单元本身的限定。
