为使本发明实施例的目的、技术方案和优点更加清楚，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，本领域普通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。
本发明实施例提供了一种直播视频的转码方法，如图1所示，具体步骤包括：
101、接收主播用户发送的流媒体数据上传请求。
其中，所述流媒体数据上传请求中携带有流媒体数据和主播用户的属性信息，所述流媒体数据为可以直播的数据。所述主播用户的属性信息具体可以为主播用户的IP信息、域名信息、位置信息、数据传输率等信息，本发明实施例不做具体限定。
对于本发明实施例，所述流媒体数据上传请求中还可以携带有主播用户请求转换的码率，所述码率具体可以为1080p、720p、1280p、1024p等，本发明实施例不做具体限定。需要说明的是，若主播用户未指定流媒体数据将要转换的码率，则将所述流媒体数据转换成默认的码率，其中默认码率可以为直播视频中所有的码率，也可以是由系统默认配置的码率，本发明实施例不做具体限定。
102、根据所述主播用户的属性信息选择实时转码服务器。
对于本发明实施例，根据主播用户的属性信息选择实时转码服务器具体
过程可以为：首先对主播用户发送的流媒体数据上传请求进行解析，从解析结果中获取主播用户的运营商、位置信息、及传输速率等信息，然后选择和主播用户的运营商相同的实时转码服务器，接着从与主播用户的运营商相同的实时转码服务器中，提取能够对主播用户位置信息进行转码的实时转码服务器，此时若可对主播用户位置信息进行转码的实时转码服务器存在多个，则还需要进一步的获取可对主播用户位置信息进行转码的实时转码服务器的负载信息，最后从中选择一个负载较大的实时转码器。对于本发明实施例，实时转码服务器可将流媒体数据实时转换成多种码率，以适应不同播放终端对码率的需求。
103、将所述流媒体数据发送给所述实时转码服务器，以使得所述实时转码服务器将所述流媒体数据实时转换成多种码率的流媒体数据。
进一步地，实时转码服务器将多码率的流媒体数据发送至源服务器上。其中，所述实时转码服务器和所述源服务器为分布式部署，比如在同一个运营商，同一个地区，都部署有实时转码服务器和源服务器，实时转码服务器和所述源服务器采用相同的分布式部署，可快速的将实时转码服务器中多码率的流媒体数据发送给源服务器。需要说明的是，分布式部署的实时转码服务器，每一个位置区域当中包含一个或多个实时转码服务器，每个实时转码服务器对应一个位置区域，即每个实时转码服务器仅可对区域范围内的流媒体数据进行转码。
进一步地，在实时转码服务器将流媒体数据转换成多种码率的流媒体数据之后，还可以判断流媒体数据的格式是否为标准的视频格式，若流媒体数据的格式不是标准的视频格式，则还需要将流媒体数据转换成标准的数据格式，然后将标准格式的多码率流媒体数据发送给源服务器。其中，标准的视频格式为常见的播放器能够播放的格式，如rmvb，wmv，avi等，本发明实施例不做具体限定。
对于本发明实施例，根据接收到的流媒体数据上传请求中的主播用户属性信息，选择与主播用户服务器最近的实时转码服务器，然后通过所述实时转码服务器对将流媒体数据转换成多种码率的流媒体数据，最后将多码率的流媒体数据发送到源服务器上，从而解决了直播视频难以适应不同播放终端对码率的需求。
与上述方法相对应地，本发明实施例还提供了一种直播视频的转码方法，如图2所示，具体步骤包括：
201、接收主播用户发送的流媒体数据上传请求。
其中，所述流媒体数据上传请求中携带有流媒体数据和主播用户的属性信息。对于本发明实施例，所述主播用户的属性信息中包括位置信息，运营商信息和标识信息，所述位置信息用于表示主播用户所在的地理位置，运营商信息表示主播用户所使用的网络运营商，具体可以为联通、电信、移动等，本发明实施例不做具体限定。所述标识信息为主播用户想在直播视频上打标识的信息，例如标识信息具体可以为电视台台标、图形图标、文字图标等。在本发明实施例中，通过在流媒体数据上传请求中增加标识信息，可在用户请求播放直播视频时，在直播视频上显示所述标识信息。
202、选择与所述运营商信息对应的实时转码服务器。
例如，主播用户的运营商为电信，则从分布式部署的实时转码服务器中，选择所有运营商的为电信的实时转码服务器。在本发明实施例中，由于同一运营商的服务器之间传输速率高，因此选择与运营商信息对应的实时转码服务器，可在后续步骤中提高流媒体数据在主播用户服务器和实时转码服务器之间的传输速度。
203、从与所述运营商信息对应的实时转码服务器中，提取能够对所述位置信息进行转码的实时转码服务器。
对于本发明实施例，提取能够对所述位置信息进行转码的实时转码服务器具体过程可以如下：首先获取该位置信息所在的位置区域，然后从与所述运营商信息对应的实时转码服务器中，提取该位置区域内的实时转码服务器。
例如，主播用户的位置信息为和平区中山路123号，由于该位置信息对应的位置区域为和平区，和平区内的实时转码服务器都能够对上述位置信息中的流媒体数据转码，因此从与所述运营商信息对应的实时转码服务器中，提取能够对所述位置信息进行转码的实时转码服务器，可以满足对主播用户上传的流媒体数据进行转码的需求。
204、获取所述能够对所述位置信息进行转码的实时转码服务器的负载数据。
其中，实时转码服务器的负载数据表示实时转码服务器能够承受的数据
量。在本发明实施例中，通过获取能够对所述位置信息进行转码的实时转码服务器的负载数据，可在后续步骤根据负载均衡原则进行有效的选择实时转码服务器，从而可以提高实时转码服务器转码的效率，以及各个实时转码服务器的利用率。
205、从所述能够对所述位置信息进行转码的实时转码服务器中，筛选出负载数据小于等于预置阈值的实时转码服务器。
其中，所述预置阈值可以根据各个实时转码服务器实际负载情况进行设置，也可以由系统默认配置，本发明实施例不做具体限定。在发明实施例中，通过从能够对所述位置信息进行转码的实时转码服务器中，筛选出负载数据小于等于预置阈值的实时转码服务器，并通过负载数据小于等于预置阈值的实时转码服务器对流媒体数据进行转码，可以提高转码服务器转码的效率，以及各个实时转码服务器的利用率。
206、从所述负载数据小于等于预置阈值的实时转码服务器中，选择与所述位置信息最近的实时转码服务器。
207、将所述流媒体数据和所述标识信息发送给所述实时转码服务器。
进一步地，以使得所述实时转码服务器将所述流媒体数据实时转换成多种码率的流媒体数据，并在多种码率的流媒体数据上加上所述标识信息。并将多码率的流媒体数据发送至源服务器上；其中，所述实时转码服务器和所述源服务器为相同的分布式部署。
对于本发明实施例，首先接收主播用户发送的流媒体数据上传请求，选择与所述运营商信息对应的实时转码服务器，然后从与所述运营商信息对应的实时转码服务器中，提取能够对所述位置信息进行转码的实时转码服务器，接着获取能够对所述位置信息进行转码的实时转码服务器的负载数据，从能够对所述位置信息进行转码的实时转码服务器中，筛选出负载数据小于等于预置阈值的实时转码服务器，再从负载数据小于等于预置阈值的实时转码服务器中，选择与所述位置信息最近的实时转码服务器，最后将流媒体数据和所述标识信息发送给所述实时转码服务器，以使得所述实时转码服务器将所述流媒体数据实时转换成多种码率的流媒体数据，并在多种码率的流媒体数据上加上所述标识信息。从而解决了现有技术中直播视频难以适应不同播放终端对码率的需求。
进一步的，作为对上述方法的实现，本发明实施例提供了一种直播视频的转码装置，如图3所示，该装置包括：接收单元、选择单元和发送单元。
接收单元31，用于接收主播用户发送的流媒体数据上传请求，所述流媒体数据上传请求中携带有流媒体数据和主播用户的属性信息。所述主播用户的属性信息具体可以为主播用户的IP信息、域名信息、位置信息、数据传输率等信息。
选择单元32，用于根据所述接收单元31接收的主播用户的属性信息选择实时转码服务器。选择实时转码服务器具体过程可以为：首先对主播用户发送的流媒体数据上传请求进行解析，从解析结果中获取主播用户的运营商、位置信息、及传输速率等信息，然后选择和主播用户的运营商相同的实时转码服务器，接着从与主播用户的运营商相同的实时转码服务器中，提取能够对主播用户位置信息进行转码的实时转码服务器，此时若可对主播用户位置信息进行转码的实时转码服务器存在多个，则还需要进一步的获取可对主播用户位置信息进行转码的实时转码服务器的负载信息，最后从中选择一个负载较大的实时转码器。对于本发明实施例，实时转码服务器可将流媒体数据实时转换成多种码率，以适应不同播放终端对码率的需求。
