具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明实施例提供了一种视频播放方法及装置，其中，视频播放方法可以由智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、移动互联网设备(Mobile Internet Devices，MID)、虚拟现实(Virtual Reality，VR)设备、个人计算机(Personal Computer，PC)等具有360度视频播放功能以及数据处理功能的智能终端来实现。本发明实施例提供的视频播放方法及装置，可以自动控制观看视野的移动，实现360度视频观看轨迹的分享，以下分别进行详细说明。
请参阅图1，图1为本发明实施例提供的一种视频播放方法的流程示意图。本发明实施例中所描述的视频播放方法，包括：
101、播放终端获取目标观看轨迹文件。
本发明实施例中，该播放终端是具有360度视频播放功能的智能终端，播放终端获取到的目标观看轨迹文件，为针对360度视频预先生成的至少一个观看轨迹文件中的任意一个观看轨迹文件。播放终端获取目标观看轨迹文件的具体方式为：播放终端首先获取并显示该360度视频预先生成的至少一个观看轨迹文件的文件标识；然后接收播放终端的用户针对显示的文件标识输入的选择指令，并根据接收到的用户输入的选择指令确定用户选择的目标文件标识；最后将该目标文件标识对应的观看轨迹文件确定为目标观看轨迹文件。其中，360度视频是通过多个摄像机同时对同一个空间下的物体，进行多个角度拍摄生成的，360度视频支持多角度视频播放，故而用户在观看360度视频时，可以自由控制播放终端切换360度视频的观看角度，丰富了视频播放的形式。
102、所述播放终端根据所述目标观看轨迹文件，确定用户观看所述360度视频时的目标观看轨迹信息。
本发明实施例中，针对360度视频预先生成的每一个观看轨迹文件都包括有观看轨迹信息。播放终端在获取到目标观看轨迹文件之后，获取目标观看轨迹文件包括的目标观看轨迹信息，播放终端从而可以根据该目标观看轨迹信息确定出用户此次观看360视频时的观看轨迹。其中，该目标观看轨迹信息包括播放进度时间、视野聚焦位置和视野旋转角度等信息；该目标观看轨迹信息还包括播放进度时间、视野聚焦位置、视野旋转角度三者之间的映射关系，也即 是说根据播放进度时间可以确定出对应的视野聚焦位置和视野旋转角度；视野旋转角度是用户看向某一视野聚焦位置时，用户的头部相对于参考方向旋转的角度。
103、所述播放终端按照所述目标观看轨迹信息播放所述360度视频。
具体地，播放终端首先获取360度视频的当前播放进度时间，并从目标观看轨迹信息中确定出与当前播放进度时间对应的目标播放进度时间；然后根据目标观看轨迹信息包括的播放进度时间、视野聚焦位置和视野旋转角度之间的映射关系，确定出与目标播放进度时间对应的目标视野聚焦位置和目标视野旋转角度；最后从360度视频的多帧图像中确定出与目标视野聚焦位置和目标视野旋转角度对应的目标图像帧，并显示该目标图像帧。其中，目标图像帧即是用户的头部旋转了与目标视野旋转角度相同的角度后，用户看向目标视野聚焦位置时，用户通过播放终端的显示窗口能够看到的360度视频的画面。
前文介绍了播放终端根据360度视频的观看轨迹文件播放360度视频的方法，下面详细介绍生成360度视频的观看轨迹文件的过程。下面以播放一次360度视频为例进行说明，其他情况则可以以此类推。
具体地，播放终端在事先播放一次360度视频的过程中，每隔预设时间间隔(例如50ms)获取一次用户观看360度视频时的观看轨迹信息，每次获取到的观看轨迹信息包括播放进度时间(例如t)、视野聚焦位置(例如a)、视野旋转角度(例如r)以及三者的对应关系。请一并参见图2a和图2b，如图2a所示，用球形来表示360度视频的360度画面，点w表示播放终端的用户的眼睛，点a是球面上的一点且对应一个三维坐标，点w和点a的连线wa表示用户眼睛所观看的方向；如图2b所示，点b为球面上的参考点，点w和点b的连线wb表示参考方向。假设在观看轨迹信息获取时刻，用户的眼睛看向a点，则点a的三维坐标即为此次观看轨迹信息获取过程中获取到的视野聚焦位置a；则点w和点a的连线wa，与点w和点b的连线wb之间的夹角的大小即为此次观看轨迹信息获取过程中获取到的视野旋转角度r。其中，视野旋转角度r具有方向性，可以用视野旋转角度r的正负代表其方向，例如用正值表示顺时针方向旋转，用负值表示逆时针方向旋转。
在一些实施方式中，如图2b所示，假设b点是播放终端上一次获取观看轨迹信息时获取到的视野聚焦位置，a点是播放终端此次获取观看轨迹信息时获取到的视野聚焦位置，则同样可以用连线wa与连线wb之间的夹角的大小来表示播放终端此次获取观看轨迹信息时获取到的视野旋转角度r。故而视野旋转角度r表示用户的头部相对于，上一次获取观看轨迹信息时获取到的视野聚焦位置b与用户眼睛w的连线所在方向旋转的角度。
进一步地，在360度视频本次播放结束后，播放终端可以获取到至少一组观看轨迹信息，观看轨迹信息的格式例如是(t：a：r)，播放终端将获取到的至少一组观看轨迹信息存储到同一文件中，从而生成一个观看轨迹文件。其中，观看轨迹信息在观看轨迹文件中的存储格式例如可以是：(t1：a1：r1)，(t2：a2：r2)，(t3：a3：r3)……，(t：a：r)表示播放终端同一次获取到的播放进度时间、视野聚焦位置和视野旋转角度，进而形成了三者之间的对应关系。需要说明的是，360度视频播放一次，播放终端对应生成一个360度视频的观看轨迹文件，在多次播放360度视频后，可以对应生成多个360度视频的观看轨迹文件。
在一些实施方式中，播放终端在事先播放一次360度视频的过程中，每获取到一组用户观看360度视频时的观看轨迹信息之后，根据在360度视频的播放过程中所获取到的所有观看轨迹信息检测360度视频是否观看完成；或者，播放终端根据360度视频已经播放过的所有图像帧检测360度视频是否观看完成；若播放终端检测到360度视频观看未完成，则输出提示信息，该提示信息用于提示用户观看未完成，进一步该提示信息可以用于提示用户未观看的画面对应的视野旋转方向，从而避免用户遗漏观看信息；若播放终端检测到360度视频观看完成，则输出观看已完成提示信息，从而避免出现重复观看已经观看过的画面的问题。
在一些实施方式中，在360度视频此次播放完成，且对应得到一个360度视频的观看轨迹文件之后，播放终端可以将360度视频的观看轨迹文件存储在本地存储介质中，也可以将360度视频的观看轨迹文件存储到云端服务器中，以便于播放终端或者其他播放终端从云端服务器下载该360度视频的观看轨迹文件，并根据该360度视频的观看轨迹文件自动控制用户观看该360度视频时的画 面切换，从而实现360度视频观看轨迹的分享。
请一并参见图3a和图3b，图3a是用户通过现有方式观看360度视频时，看到的360度视频的画面以及各个画面的顺序，也即是观看360度视频时用户所看到的独特故事线。为了下次看到相同的故事线或者将看到的独特故事线分享给其他用户，播放终端在用户通过现有方式观看360度视频时，每隔预设时间间隔记录一次用户的观看轨迹信息，最后生成360度视频的观看轨迹文件，360度视频的观看轨迹文件的生成过程可参考前文描述，在此不再赘述。图3b是用户或者其他用户观看该360度视频时，播放终端根据该360度视频的观看轨迹文件自动播放360度视频的过程中，360度视频的播放画面以及各个画面的顺序，根据该360度视频的观看轨迹文件自动播放该360度视频的方法亦可参考前文描述，在此不再赘述。采用上述方式，可以使得图3b所示的播放画面以及各个画面的顺序与图3a所示的播放画面以及各个画面的顺序相同，从而实现360度视频观看轨迹，或者说故事线的分享，且不会遗漏用户想分享的关键信息，丰富了360度视频的观看形式。
本发明实施例中，首先获取目标观看轨迹文件，然后根据目标观看轨迹文件确定用户观看360度视频时的目标观看轨迹信息，最后按照目标观看轨迹信息播放360度视频，从而可以自动控制观看视野的移动，实现360度视频观看轨迹的分享。
