具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本申请实施例中的技术方案进行描述。
在本申请实施例的描述中，“示例性的”、“例如”或者“举例来说”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”、“例如”或者“举例来说”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”、“例如”或者“举例来说”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，单独存在B，同时存在A和B这三种情况。另外，除非另有说明，术语“多个”的含义是指两个或两个以上。例如，多个系统是指两个或两个以上的系统，多个终端是指两个或两个以上的终端，多路视频流是指两路或两路以上的视频流。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
图1是本申请实施例提供的一种应用场景示意图。如图1所示，用户在终端A上开启了多景录像功能。以双景录像为例，用户在终端A上选择了两个后置摄像头录制视频，并选取了分屏显示模式，此时，在终端A的显示屏幕上可以显示有两个后置摄像头的视频录制界面，即视频录制界面11和12。在双景录像过程中，本方案可以将每个摄像头录制的视频文件均按照单独的视频文件存储，即将两个后置摄像头录制的视频文件按照两个视频文件存储，而不是按照一个视频文件存储，也即是说，各个摄像头录制的视频文件分别单独存储。此外，在双景录制过程中，本方案也可以生成一个或多个描述文件，该描述文件中可以包括各个摄像头的视频录制信息和录制视频过程中用户的操作信息。其中，视频录制信息包括以下一项或多项：各个摄像头的起始录制时间，各个摄像头的标识信息，各个摄像头的录制界面的显示方式，视频拍摄比例，或者，视频录制过程中，多个摄像头所属终端的显示屏幕的旋转角度；操作信息包括以下一项或多项：各个摄像头的录制界面的尺寸调整信息，各个摄像头的录制界面的显示调整信息，或者用户对各个摄像头的录制界面每次操作的起始时间。
在双景录像完毕后，当用户可以选择播放其中一个视频文件时，终端A可以基于该描述文件将剩余摄像头录制的视频文件自动加载至播放界面上，从而还原双景录制过程。当用户选择编辑其中一个视频文件时，终端A也可以基于该描述文件将剩余摄像头录制的视频文件自动加载至编辑界面上，从而还原双景录制过程，进而使得用户可以同时编辑各个摄像头录制的视频文件。当用户选择同时分享双景录像产生的各个视频文件时，终端A也可以基于该描述文件将各个摄像头录制的视频文件进行合成，然后再分享合成后的视频文件，其中，合成后的视频文件可以呈现双景录制过程。

接下来，基于图1所示的应用场景和图2所示的电子设备的硬件结构，以双景录像为例，对本方案的多景录像过程进行详细说明。
(1)用户选择双景录制模式
用户可以在终端上开启双景录制功能，以启动双景录制模式。在启动双景录制模式后，可以列出终端上各个摄像头，以供用户选择两路视频流。例如，如图3a所示，终端B上配置有四个摄像头，用户在启动双景录制模式后，终端B的显示界面上可以将四个摄像头列出，即图3a中的前置摄像头，后置主摄像头，后置超广角摄像头和后置长焦摄像头。
(2)用户选择双景录制所需的摄像头
终端在列出各个摄像头后，用户可以任意选择两个摄像头。例如，如图3a所示，用户可以选择后置主摄像头和后置长焦摄像头，也可以选择后置主摄像头和前置摄像头，等等。其中，用户在选择摄像头时，可以通过触控选择，也可以通过声控选择，在此不做限定。
(3)双景录制
在用户选择出两个摄像头后，即可以录制视频。在双景录制过程中，各个摄像头所采集的视频的呈现方式可以是默认的，例如，默认是分屏显示(如左右分屏或上下分屏等)或画中画显示等。示例性的，如图3b所示，当用户选择的两个摄像头为后置主摄像头和后置长焦摄像头时，可以默认是分屏显示；如图3c所示，当用户选择的两个摄像头为后置主摄像头和前置摄像头时，可以默认是画中画显示。
在双景录制过程中，各个摄像头所采集的视频文件可以分别编码存储。例如，前置摄像头录制的视频文件为视频1，后置主摄像头录制的视频文件为视频2，则可以将这视频1和视频2单独存储，而不是将视频1和视频2合成为一个视频文件进行存储。可以理解的是，分别编码存储的视频文件之间可以具有关联关系，例如通过文件名或数据库记录将此次录制的 各个视频文件进行关联。
在双景录制过程中，可以生成与双景录制所产生的视频相关联的描述文件。该描述文件中可以包括各个摄像头的视频录制信息和录制视频过程中用户的操作信息。其中，视频录制信息包括以下一项或多项：各个摄像头的起始录制时间，各个摄像头的标识信息，各个摄像头的录制界面的显示方式，视频拍摄比例，或者，视频录制过程中，多个摄像头所属终端的显示屏幕的旋转角度；操作信息包括以下一项或多项：各个摄像头的录制界面的尺寸调整信息，各个摄像头的录制界面的显示调整信息，或者用户对各个摄像头的录制界面每次操作的起始时间。
为更好理解，举例说明描述文件的格式。如图4a所示，描述文件中可以包括描述双景视频整体相关的信息，该信息可以与录制时间轴无关。在图4a中，有各个摄像头的名称，如：主摄像头(Main-Lens)，前置摄像头(Front-Lens)；有各个摄像头录制的视频文件的名称，如：VideoFile0:VID_YYYYMMDD_HHMMSS_Main，VideoFile1:VID_YYYYMMDD_HHMMSS_Front；有双景录制时各个摄像头所采集的视频的呈现方式，如Picture-In-Picture of Main-Lens//后置主摄为大图的画中画；有横竖屏类型，如：90(即竖屏)，当为180时为横屏；有视频拍摄比例，如：16/9。如图4b所示，描述文件中也可以包括按照时间轴进行录制过程的记录，该记录可以记录画面发生改变的过程，如：在第10秒左右发生了前后摄像头画面的切换，在第15秒左右发生了画中画框的拖动，并在第20秒左右结束。可以理解的是，在用户拖拽画中画框的过程中，由于拖拽是自由无规则拖动，为了能够在后期复现用户的拖拽操作，因此可以记录拖拽轨迹，例如，以画中画矩形中心点为基准点画出拖动轨迹曲线并记录为文件，如图5所示，该图示出了拖动轨迹曲线。
生成描述文件后，可以将该描述文件与分别单独存储的各个摄像头录制的视频文件进行关联。例如，通过文件名或数据库记录将它们进行关联。
在用户结束双景录制时，即完成双景录制。
(4)播放双景录制的视频文件
用户可以选择任一双景录制的视频文件进行播放。当其中一个视频文件处于播放状态时，终端可以基于描述文件与分别单独存储的各个摄像头录制的视频文件之间的关联关系，将其他的视频视频文件与该视频文件进行叠加进行呈现。叠加时呈现方式则可以以描述文件进行还原。例如，若描述文件中记录的呈现方式为分屏显示，则以分屏显示的方式将各个视频文件叠加进行呈现。也即是说，在其中一个视频文件(如视频文件1)处于播放状态时，可以基于生成的描述文件，将与该视频文件(如视频文件1)相关联的其他视频文件(如视频文件2)自动加载至该视频文件(如视频文件1)的播放界面上。示例性的，在播放视频文件1的过程中，可以获取当前播放时间信息，然后基于当前播放时间信息从描述文件中查找当前播放时间下其他视频文件的播放状态，然后，再基于其他视频文件的播放状态，将其他视频文件加载至视频文件1的播放界面上。
在播放双景录制的视频文件过程中，当描述文件中记录了在某一时间点发生过用户交互变化(如分屏窗口的比例调整、画中画的切换等)，也可以按描述文件进行还原，进而在播放过程中对应的调整播放画面，以实现播放与用户录制过程一致的效果。例如，描述文件中记录的是在第10秒至第15秒，用户拖拽了一个画面，则播放到第10秒时，依据描述文件中记录的用户的拖拽轨迹，开始复现用户的拖拽操作。
可以理解的是，在播放双景录制的视频文件过程中，各个视频文件均可以处于只读状态， 此外，已生成的描述文件也可以处于只读状态。此外，本方案中描述的视频文件处于播放状态，可以是指用户已选择播放该视频文件，即终端接收到用户下发的播放指令，但终端还未开始播放该视频文件，此阶段可以理解为预备播放状态；也可以指终端接收到用户下发的播放指令后，终端已开始播放该视频文件，此阶段可以理解为正式播放状态。示例性的，如图6所示，视频文件VideoFi le0在00:00:000时还未正式播放，此时可以加载其他的视频文件VideoFi le1，在加载过程中可以基于已生成的描述文件确定出横竖屏类型；当播放时间到00:10:500时，描述文件中记录有检测到画面变化，此时可以读取画面变化的轨迹图，并基于该轨迹图复现画面变化过程；在播放时间到00：20:300时，描述文件中记录有检测到画面变化结束，此时即可以结束复现画面变化过程。
(5)编辑双景录制的视频文件
用户可以选择任一双景录制的视频文件进行编辑。当其中一个视频文件处于编辑状态时，终端可以基于描述文件与分别单独存储的各个摄像头录制的视频文件之间的关联关系，将其他的视频文件与该视频文件进行叠加进行呈现。叠加时呈现方式则可以以描述文件进行还原。例如，若描述文件中记录的呈现方式为分屏显示，则以分屏显示的方式将各个视频文件叠加进行呈现。也即是说，在其中一个视频文件(如视频文件1)处于播放状态时，可以基于生成的描述文件，将与该视频文件(如视频文件1)相关联的其他视频文件(如视频文件2)自动加载至该视频文件(如视频文件1)的编辑界面上。
在编辑双景录制的视频文件过程中，可以同步记录用户对各个视频文件的编辑信息。之后，再基于记录的编辑信息，更新在双景录制过程中生成的描述文件。其中，编辑信息可以包括以下一项或多项：至少一路视频流的显示界面的尺寸大小，至少一路视频流的显示界面的位置，至少一路视频流的声音大小，或者，用户对至少一路视频流每次编辑的起始时间。可以理解的是，一路视频流可以对应一个视频文件。示例性的，用户的编辑操作可以包括：多景界面的调整，如分屏画面的大小调整与画中画的切换与拖动等；也可以包括选定某一画面进行音频静音处理等。举例来说，如图7所示，记录的用户的编辑信息为：在00:00:08:200时将主摄像头录制的视频文件进行了静音处理，在00:00:10:500时进行了画中画切换处理，在00:00:15:100时开始进行画中画拖动处理，在00:00:20:300时结束画中画拖动处理，在00:00:21:100时将主摄像头录制的视频文件解除了静音。
可以理解的是，用户对各个视频文件的编辑操作，还可以包含对视频文件进行滤镜、文字、音乐、水印边框的叠加等等。用户在编辑操作中所使用的相关静态资源(如音乐、水印边框等)也可以与描述文件一同存储，以使得在后期播放时，可以直接调用相关静态资源。
需说明的是，本方案中，用户在对各个视频文件进行编辑时，原始视频文件并不会被修改。在后期分享编辑后的视频文件时，可以基于更新后的描述文件，在原始视频文件的基础上复现编辑后的视频文件。
(6)分享双景录制的视频文件
用户可将多个视频文件进行分享，分享时可选择单独的一个视频文件分享或者将多个视频文件合并后分享。例如，如图8所示，用户可以选择分享画中画视频，即多个视频文件；也可以选择分享剪辑视频，即用户编辑过的视频文件；还可以选择分享前景视频或者后景视频，即单个视频文件。可以理解的是，在图8中用户除了可以选择分享画中画视频外，也可以选择其他模式的视频，例如分屏模式的视频，其中，画中画视频和分屏模式的视频可以称之为多景录像视频。
本方案中，视频文件合并分享时的逻辑与视频文件播放或编辑时的逻辑相似，同样从描述文件中读取录制过程中每个视频文件的状态、叠加的编辑效果等，然后再将多个视频文件合成为一个视频文件分享至社交平台或者其他设备。也即是说，在用户下发视频分享请求后，可以基于已生成或者更新的描述文件将各个摄像头录制的视频文件合成为一个视频文件，然后再将合成后的视频文件进行分享。示例性的，可以将需要合成的视频文件，以及相应的描述文件写入缓存流中，之后，可对该缓存流进行压缩处理，以得到合并后的视频文件。示例性的，在合成视频文件时，还可以先建立每个视频文件中视频帧与时间戳之间的对应关系，然后，再将同一时间戳对应的多个视频帧合成一个视频帧，其中，在合成时，可以基于描述文件中该时间戳下各个视频帧所处的位置，确定合成后的各个视频帧合并后再同一界面中的位置；最后，再将多个合成后的视频帧进行处理，得到合成后的视频文件。
为了便于理解上述所描述的双景录像过程，下面基于上文的描述，继续以双录视频录像举例说明。可以理解，下述为描述是上文的另一中表达方式，两者是相结合的。
对于双景录像过程：如图9所示，首先，在终端上启动双录视频录制。接着，终端上列举出所有摄像头视频流。之后，用户可以选择两路视频流进行采集，以及选择双录视频记录形式，如分屏或画中画。之后，用户所选择的摄像头可以采集双录视频并分别单独编码为视频，即产生视频文件1和视频文件2两个视频文件。同时在录制过程中，记录双录视频操作过程，并生成记录文件(即上文所提及的描述文件)。最后，将双录视频与记录文件进行关联即可。
对于双景视频浏览过程：如图10所示，首先，用户在终端上启动视频浏览。接着，终端读取双录视频关联信息，以确定出视频文件1、视频文件2和记录文件(即上文所提及的描述文件)。然后，终端中的播放器可以按记录文件将双录视频进行合并播放。
对于双景视频编辑过程：继续参阅图10，首先，用户在终端上启动视频浏览。接着，终端读取双录视频关联信息，以确定出视频文件1、视频文件2和记录文件(即上文所提及的描述文件)。然后，终端可以按记录文件重现双录视频。接着，用户重新调整视频，并对某路视频进行编辑处理。最后，基于用户的编辑信息，更新记录文件(即上文所提及的描述文件)。
接下来，基于上文的描述，以双景录像为例，对本方案中所提及的终端上所涉及的功能模块进行介绍。可以理解的是，以下介绍的功能模块可以用来实现上文描述的双景录制过程，各个功能模块详细的工作过程，可参见上文双景录制过程中的描述，在此就不再一一赘述。此外，终端中涉及的各个功能模块的实现均可以但不限于由上述图2中所描述的电子设备200中的处理器210来实现。
如图11所示，本方案中，终端中可以包括摄像头选择模块31，视频采集模块32，双景视频描述文件生成模块33，双景视频关联模块34，双景视频播放模块35，双景视频编辑模块36和双景视频分享模块37。
其中，摄像头选择模块31可以采集终端的各个摄像头视频流，也即采集各个摄像头拍摄的视频。
视频采集模块32可以基于摄像头选择模块31，选定2路视频流输出，输出时将双路视频分别编码保存。视频采集模块32可以按默认方式呈现2路视频流，如画中画或分屏。其中，当为多景录像时，视频采集模块32也可以输出大于2路的视频流，例如3路视频流，或者4 路视频流等。
双景视频描述文件生成模块33可以在视频采集模块32输出两个视频文件的同时，生成与该双景视频相关联的描述文件。示例性的，描述文件中可以包括时间、类型、模式、横竖屏、分辨率等等。
双景视频关联模块34可以将分别记录的两个视频文件、一个描述文件通过特定方式进行关联，关联的逻辑可通过文件名或者通过数据库记录关联。
双景视频播放模块35可以在用户选择任一双景视频进行播放时，基于双景视频关联模块34提供的关联关系，将另一路视频与该路视频进行叠加，叠加时呈现方式则完全以关联的描述文件进行还原。
双景视频编辑模块36可以在用户进行双景视频进行编辑时，同步将编辑操作写入关联的描述文件，即基于用户的编辑信息，更新双景视频描述文件生成模块33生成的描述文件。示例性的，双景视频编辑模块36可以提供给用户进行选择显示方式编辑。
双景视频分享模块37使用户可以按需分享，例如分享一个或多个视频文件。在用户选择分享多个视频文件时，双景视频分享模块37可以将多个视频文件合成为一个视频文件分享至社交平台或其他设备。
接下来，基于上文所描述的多景录像过程，介绍本申请实施例提供的一种多景录像方法。可以理解的是，该方法是上文所描述的多景录像过程的另一种表达方式，两者是相结合的。该方法是基于上文所描述的多景录像过程提出，该方法中的部分或全部内容可以参见上文对多景录像过程的描述。
请参阅图12，图12是本申请实施例提供的一种多景录像方法的流程示意图。可以理解，该方法可以通过任何具有计算、处理能力的装置、设备、平台、设备集群来执行。如图8所示，该多景录像方法包括：
