具体实施方式
为了使本技术领域的人员更好地理解本发明方案，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。
在本发明的说明书和权利要求书及上述附图中的描述的一些流程中，包含了按照特定顺序出现的多个操作，但是应该清楚了解，这些操作可以不按照其 在本文中出现的顺序来执行或并行执行，操作的序号如101、102等，仅仅是用于区分开各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、终端、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。
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，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-图2，本发明的一个实施例提供一种直播编码的方法，图1所示的为该直播编码的方法流程图，其包括：
步骤101：采集视频信息，获取所述视频信息的视频屏幕方向；其中，视频屏幕方向为视频信息中每帧画面的方向，譬如如图2所示的方向为横向。
具体地，采集视频信息可以通过终端的摄像设备来获取，包括但不限于前置或后置的一个或者多个摄像头。在一些实施方式中，采集视频信息还可以通过外接摄像设备进行，本发明实施例对此不作限制。
获取视频信息的视频屏幕方向可以通过根据重力感应器的感应信号来获取，譬如，假设目前的移动终端是竖向放置，当将该移动终端左转或者右转90度时，也即是横向放置，则会有相应的感应信号产生。考虑到一般情况下，视频信息的每帧画面的方向，也即视频屏幕方向与移动终端放置状态相一致，因此可以根据该重力感应器的感应信号来获取视频屏幕方向，这样的获取方式具有获取方便，简单易行且成本低廉的效果。
当然，考虑到重力感应器与加速度感应器在一定程度上功能是等同的，在一些实施方式中，还可以根据加速度感应器来获取视频屏幕方向，具体原理参考上述。
步骤103：比较所述视频屏幕方向与预置视频屏幕方向，若所述视频屏幕方向与预置视频屏幕方向不同时，则生成调整指令；其中，预置视频屏幕方向为直播方案设定的标准播放方向，譬如说为竖向，这样播放端默认的播放方向为竖向，于是用户通过竖向的观看模式就可以看到高品质的播放效果，当然， 直播方案设定的标准播放方向也可以是横向；调整指令为一个提示信息，用于表征视频屏幕方向与预置视频屏幕方向的不同。
在一些实施方式中，调整指令携带有偏转角度值，则生成调整指令包括：计算视频屏幕方向与预置视频屏幕方向偏转角度值；根据偏转角度值生成调整指令，其中偏转角度值为视频屏幕方向与预置视频屏幕方向的偏转值。
在具体实施计算偏转角度值时，可以以预置视频屏幕方向为标准方向建立一个坐标系，通过视频屏幕方向相对于预置视频屏幕方向偏向角来获取偏转角度值，譬如说，默认预置视频方向为竖向时，当移动终端由竖向向左转90度时，则偏转角度值为负90度；向右转90度时，则偏转角度值为正90度。
步骤105：发送所述视频信息以及所述调整指令至联动编码服务器，以使所述联动编码服务器根据所述调整指令将所述视频信息的所述视频屏幕方向调整为预置视频屏幕方向；其中，联动编码服务器为一台装有特定视频编码软件的计算机，值得一提的是，其还可以通过特定的编码来调整视频的帧率、码率等。
具体地，在一些实施方式中，视频信息以及调整指令可以通过HTTP传输协议或者HTTPS传输协议或者TCP协议发送至联动编码服务器。
匹配地，请参阅图3，本发明实施例还提供一种直播编码的方法，图3示出了该直播编码的方法的流程图，其包括：
步骤301：接收终端采集的视频信息以及在视频信息的视频屏幕方向与预置视频屏幕方向不同时生成的调整指令；其中，该步骤301中的视频信息对应于步骤101中的视频信息；该步骤301中的调整指令对应于步骤103中的调整指令，因此关于具体细节不再赘述。
在一些实施方式中，接收视频信息以及调整指令可以通过HTTP传输协议或者HTTPS传输协议或者TCP协议。
步骤303：根据所述调整指令将所述视频信息的视频屏幕方向调整为预置视频屏幕方向；其中，步骤303中的预置视频屏幕方向与步骤103中的预置视频屏幕方向相对应。
具体地，将视频信息的视频屏幕方向调整为预置视频屏幕方向可以通过旋转矩阵编码的方式实现。
旋转矩阵在旋转角度较小的情况下可以通过两次错切变化得到预置视频屏幕方向，在旋转角度较大的情况下可以通过三次等价错切得到预置视频屏幕方向，在实际中，对于旋转角度超过90度，可以首先旋转特殊角度90，180，270，然后在旋转剩下的角度数。其中，旋转矩阵到三次等价错切矩阵等式如下：
Figure PCTCN2017104466-appb-000001
其中，错切变换是基本的图像几何变换，首先在X方向进行顺时针的错切变换，然后在Y方向进行顺时针的错切变换，最后再到X方向进行顺时针错切变换，最终得到旋转角度以后的图像数据。
示例地，当默认预置视频方向为竖向时，当移动终端由竖向向左转90度、也即偏转角度值为负90度时，通过对视频信息每帧画面的像素通过转换矩阵即可将其横向的视频信息转为竖向的视频信息。由于该旋转矩阵是基于像素操作，没有减少像素，因此在一定程度上保证了画面的高清度，在一定程度上创造了带给用户良好视觉体验的前提。
与现有技术相比，本发明实施例一种直播编码的方法通过联动编码服务器调整采集的视频信息的视频屏幕方向，使得视频屏幕方向与预置视频屏幕方向相一致，进而统一了采集的视频信息的视频屏幕方向，同时避免了对视频信息的裁剪，在一定程度上提升了用户的观看体验。
请参阅图4，基于同一个发明构思本发明实施例提供一种直播编码的装置，其包括采集获取模块4001、比较生成模块4003以及发送模块4005，其中，
采集获取模块4001，用于采集视频信息，获取视频信息的视频屏幕方向；

在一些实施方式中，预置视频屏幕方向为竖屏。
在一些实施方式中，预置视频屏幕方向为横屏。
在一些实施方式中，采集获取模块4001包括获取单元，用于根据重力感应器的感应信号获取视频信息的视频屏幕方向。
优选地，比较生成模块4003包括：

与现有技术相比，本发明实施例一种直播编码的装置通过采集获取模块4001、比较生成模块4003、发送模块4005的设置，使得视频屏幕方向与预置视频屏幕方向相一致，进而统一了采集的视频信息的视频屏幕方向，同时避免了对视频信息进行裁剪，在一定程度上提升了用户的观看体验。
