背景技术
网络直播系统是一种将主播用户的直播视频流广播至多个观众用户进行观看的互联网系统。网络直播系统通常按照频道或房间或直播间来进行直播单位的划分。同一个直播间通常包括：一个主播客户端和多个观众客户端。
相关技术中还存在一种多主播共同直播的方法：第一主播客户端邀请第二主播客户端进行共同直播，第一主播客户端向服务器发送第一视频流，第二主播客户端向服务器发送第二视频流，服务器将第一视频流和第二视频流合并为直播视频流，然后服务器将直播视频流通过广播或组播技术发送给同一个直播间内的观众客户端，各个观众客户端接收并显示该直播视频流，该直播视频流的视频画面中以组合形式显示第一视频流的视频画面和第二视频流的视频画面，组合形式包括：大小窗组合形式、上下分屏组合形式和左右分屏组合形式中的任意一种。
由于很多观众客户端运行在小屏幕终端上，比如手机，小屏幕终端难以同时清楚地以组合形式显示第一视频流的视频画面和第二视频流的视频画面，所以对于小屏幕终端，服务器需要将第一视频流的视频画面和第二视频流的视频画面进行裁剪处理，将裁剪处理后的第一视频流和第二视频流合并为处理后的直播视频流，再把处理后的直播视频流发送给小屏幕终端中的观众客户端进行显示。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种实施环境的示意图。该实施环境包括：多个主播客户端110、服务器120、第一显示设备130和第二显示设备140。
主播客户端110为用于进行视频直播的客户端，用户可以通过主播客户端进行视频直播。主播客户端110可以安装在诸如手机、平板电脑、PC(Personal Computer，个人计算机)等本身具有摄像功能或者可以借助摄像设备进行视频录制电子设备中。
服务器120可以是一台服务器，也可以是由若干台服务器组成的服务器集群，或者是一个云计算服务中心。
第一显示设备130可以是手机、平板电脑、可穿戴设备等具备显示屏幕且支持多媒体播放功能的电子设备。
第二显示设备140可以是电视机、投影仪、PC等具备较强显示能力的多媒体播放设备，其中，显示能力包括显示屏的大小和/或显示屏的分辨率。
在本实施环境中，主播客户端110、服务器120和第一显示设备130和之间通过无线的方式进行连接。通常情况下，主播客户端110、服务器120、第一显示设备130之间通过无线网络的方式进行连接，但也不排除其它的无线连接方式。第一显示设备130和第二显示设备140之间可通过DLAN(DIGITAL LIVING NETWORK ALLIANCE，数字生活网络联盟)、无线播放(Airplay)、镜像技术(Mirror Cast)进行视频流的传输。
图2A是根据一示例性实施例示出的一种直播显示方法的流程图，本实施 例以该直播显示方法应用于图1所示实施环境中进行举例说明。该直播显示方法可以包括如下几个步骤：
在步骤201中，服务器向第一显示设备发送直播视频流。
其中，直播视频流由多个视频流合并得到。
在本实施例中，用户可以通过第一显示设备上安装的观众客户端观看多个主播的共同直播画面，然而由于很多观众客户端运行在例如手机等小屏幕的终端上，每个主播的直播画面的大小可能都大于第一显示设备的屏幕的大小。因此，第一显示设备无法完整的显示每个主播的直播画面。服务器将直播视频流发送给第一显示设备以供第一显示设备显示。以用户观看主播A和主播B的共同直播画面为例，服务器向第一显示设备发送直播视频流，该直播视频流由主播A的第一视频流和主播B的第二视频流合并得到。若第一显示设备的显示屏的为16∶9，主播A和主播B录制的视频画面也默认为16∶9，以左右分屏方式合并第一视频流的视频画面和主播B的第二视频流的视频画面为例，每个主播分到的视频画面是16∶4.5。
在一种可能的实施方式中，服务器向第一显示设备发送的直播视频流中携带预定标识，该预定标识用于指示上述直播视频流由多个视频流合并得到。
相应地，第一显示设备接收服务器发送的直播视频流。
在步骤202中，第一显示设备检测上述直播视频流是否由多个主播视频流合并得到。
在一种可能的实施方式中，第一显示设备检测直播视频流中是否携带预定标识，当检测到直播视频流中携带预定标识时，执行步骤203。
在步骤203中，当直播视频流由多个主播视频流合并得到时，第一显示设备检测是否存在第二显示设备。
第一显示设备检测是否存在其它可用于显示视频流的第二显示设备。
在一种可能的实施方式中，步骤203可以包括如下几个子步骤：
1、通过预定共享协议进行设备发现。
第一显示设备通过预定共享协议进行设备发现，预定共享协议包括DLAN、Airplay、Mirror Cast中的至少一种。换句话说，第一显示设备通过预定共享协议检测周围是否存在同样支持预定共享协议的第二显示设备。
2、在存在设备发现结果时，确定存在第二显示设备。
在存在设备发现结果时，第一显示设备则确定存在第二显示设备。即当第 一显示设备检测到周围存在同在支持预定共享协议的第二显示设备时，确定存在第二显示设备。
另外，在本实施例中，第二显示设备的显示能力优于第一显示设备，显示能力包括显示屏的大小和显示屏的分辨率中的第一项或者全部两项。以第一显示设备为手机为例，第二显示设备在通常情况下可以为电视机、投影仪、PC等显示屏幕大于手机或者是显示屏分辨率高于手机的电子设备。
可选地，第一显示设备可能检测到存在多个第二显示设备。当第一显示设备检测到存在第二显示设备时，显示设备列表。设备列表中包括检测到的第二显示设备，当获取到对应于设备列表中的第二显示设备的选择操作信号时，则将被选择的第二显示设备确定为第二显示设备。结合参考图2B，其示出了一种显示设备列表的示意图。以第一显示设备检测到存在的第二显示设备为电视1和电视2为例，第一显示设备显示设备列表20，设备列表20中包括电视1和电视2，当获取到对应于电视1的选择操作信号时，则将电视1确定为第二显示设备。
在步骤204中，若存在第二显示设备，则第一显示设备将直播视频流共享至第二显示设备进行显示。
在一种可能的实施方式中，第一显示设备在接收到服务器发送的直播视频流时，将直播视频流共享至第二显示设备按照预定组合方式进行显示。
以用户观看主播A和主播B的共同直播画面为例，结合参考图2C，其示出了一种第二显示设备显示直播画面的示意图。在图2C中，(a)部分为以左右分屏方式组合主播A的第一视频流的视频画面和主播B的第二视频流的视频画面得到的直播视频流的视频画面；(b)部分为以上下分屏方式组合主播A的第一视频流的视频画面和主播B的第二视频流的视频画面得到的直播视频流的视频画面；(c)部分为以大小窗方式组合主播A的第一视频流的视频画面和主播B的第二视频流的视频画面得到的直播视频流的视频画面。

在步骤205中，第二显示设备显示直播视频流。
可选地，第二显示设备按照预定组合方式进行显示。
综上所述，本实施例提供的方法，通过第一显示设备接收服务器发送的直播视频流之后，检测是否存在第二显示设备，在存在第二显示设备的情况下，将直播视频流共享至第二显示设备显示；解决了相关技术中将裁剪后的第一视频流和第二视频流合并为处理后的直播视频流发送给第一显示设备显示所存在的无法完整显示主播客户端录发送的视频流的画面的问题；达到了使用显示能力更优的第二显示设备完整清楚地显示视频流的画面的技术效果，使得用户能够观看完整的视频画面。
另外，通过以左右分屏方式、上下分屏方式、大小窗方式等预定组合方式组合多个视频流的视频画面，为用户提供了更加多样化的视频画面。
图3A是根据一示例性实施例示出的一种直播显示方法的流程图，本实施例以该直播显示方法应用于图1所示实施环境中进行举例说明。该直播显示方法可以包括如下几个步骤：
在步骤301中，多个主播客户端将录制的多个视频流发送给服务器。
主播在使用主播客户端进行共同直播时，每个主播客户端将录制的视频流发送给服务器，且每个主播客户端发送的视频流都是未经过裁剪处理和/或压缩处理的。以用户观看主播A和主播B的共同直播画面为例，主播A的主播客户端将主播A的第一视频流发送给服务器，主播B的主播客户端将主播B的第二视频流发送给服务器，且第一视频流和第二视频流都未经过裁剪处理和/或压缩处理。
相应地，服务器接收多个主播客户端发送的多个视频流。
在步骤302中，服务器对多个视频流中至少一个视频流的视频画面进行裁 剪处理和/或压缩处理。
为了在具有较小屏幕的第一显示设备中显示主播的共同直播画面，服务器需要对主播客户端发送的视频流的视频画面进行裁剪处理和/或压缩处理。以用户观看主播A和主播B的共同直播画面为例，当服务器以左右分屏方式或者上下分屏方式组合主播A的第一视频流和主播B的第二视频流时，服务器对第一视频流的视频画面和第二视频流的视频画面进行裁剪。当服务器以大小窗方式组合主播A的第一视频流和主播B的第二视频流时，服务器对第一视频流的视频画面和第二视频流的视频画面进行裁剪处理和/或压缩处理。
在步骤303中，服务器将处理后的多个视频流合并，得到处理后的直播视频流。
服务器以预定组合方式组合经过裁剪处理和/或压缩处理的多个视频流，得到处理后的直播视频流。预定组合方式包括：大小窗方式或者左右分屏方式或者上下分屏方式。
在步骤304中，服务器将处理后的直播视频流发送至第一显示设备。
在一种可能的实施方式中，处理后的直播视频流中携带预定标识，该预定标识用于指示所述处理后的直播视频流由多个处理后的主播视频流合并得到。
相应地，第一显示设备接收服务器发送的处理后的直播视频流。
在步骤305中，第一显示设备检测上述处理后的直播视频流是否由多个处理后的多个视频流合并得到。
在一种可能的实施方式中，第一显示设备检测上述处理后的直播视频流中是否携带预定标识，当检测到上述处理后的直播视频流中携带预定标识，则执行步骤306。
在步骤306中，若存在第二显示设备，则第一显示设备检测是否存在第二显示设备。
其中，第二显示设备的显示能力优于第一显示设备。
在步骤307中，若存在第二设备，第一显示设备向服务器发送处理前的直播视频流获取请求。
相应地，服务器接收第一显示设备发送的处理前的直播视频流获取请求。
在步骤308中，服务器将多个视频流合并，得到处理前的直播视频流。
处理前的直播视频流由多个处理前的主播视频流合并得到。
在步骤309中，服务器将处理前的直播视频流发送给第一显示设备。
相应地，第一显示设备接收服务器发送的处理前的直播视频流。
在步骤310中，第一显示设备将处理前的直播视频流共享至第二显示设备。
在一种可能的实施方式中，第一显示设备按照预定组合方式，将处理前的直播视频流共享至第二显示设备。
可选地，第一显示设备将处理前的直播视频流共享至第二显示设备之后，与第二显示设备同步显示处理前的直播视频流。
相应地，第二显示设备接收第一显示设备共享的处理前的直播视频流。
在步骤311中，第二显示设备显示处理前的直播视频流。
综上所述，本实施例提供的方法，通过第一显示设备接收服务器发送的直播视频流之后，检测是否存在第二显示设备，在存在第二显示设备的情况下，将直播视频流共享至第二显示设备显示；解决了相关技术中将裁剪后的第一视频流和第二视频流合并为处理后的直播视频流发送给第一显示设备显示所存在的无法完整显示主播客户端录发送的视频流的画面的问题；达到了使用显示能力更优的第二显示设备完整清楚地显示视频流的画面的技术效果，使得用户能够观看完整的视频画面。
另外，通过对主播视频流的视频画面进行裁剪处理和/或压缩处理，将处理后的直播视频流发送给第二显示设备，使得第二显示设备可以显示和自身显示屏幕相匹配的直播视频流的视频画面。
另外，通过以左右分屏方式、上下分屏方式、大小窗方式等预定组合方式组合多个视频流的视频画面，为用户提供了更加多样化的视频画面。
需要说明的一点是，在上述实施例中，服务器还将直播视频流发送给主播客户端，使得主播客户端显示直播视频流。换句话说，在主播通过主播客户端与其他主播共同直播时，主播客户端显示的视频画面和第一显示设备显示的画面相同，都是显示的直播视频流的视频画面。以用户观看主播A和主播B的共同直播画面为例，若直播视频流中的2个视频流的视频画面是以左右分屏方式进行组合，则第一显示设备和主播客户端显示的都是主播A的第一视频流的视频画面和主播B的第二视频流的视频画面以左右分屏方式组合而成的直播视频流的视频画面。
另外，对于主播而言，在主播客户端中只能看到裁剪处理和/或压缩处理前的不完整的视频画面，无法查看完整的视频画面。在一种可能的实施方式中， 在主播客户端的显示界面中还显示目标操作控件，该目标操作控件用于触发以大小窗方式显示与主播对应的处理前的视频画面。结合参考图3B，其示出了一种主播客户端的界面示意图。当主播客户端获取到主播B对应于目标操作控件31的触发操作时，在显示界面中以大小窗方式显示主播B完整的视频画面32。
需要说明的是，上述实施例中有关第一显示设备侧的步骤可以单独实现成为第一显示设备一侧的直播显示方法，有关服务器的步骤可以单独实现成为服务器一侧的直播显示方法，有关第二显示设备一侧的步骤可以单独实现成为第二显示设备一侧的直播显示方法，有关主播客户端侧的步骤可以单独实现成为直播客户端一侧的直播显示方法。
