本申请所提供的多媒体上墙方法，用于将多媒体流采集源所采集的多媒体流传输到显示屏上进行上墙显示，所谓“上墙显示”指的是将系统中的一个或多个多媒体采集源所采集的多媒体流以一些预设的显示方式显示在显示屏上，其中，预设的显示方式可以为将一个多媒体采集源所采集的多媒体流在显示屏上进行全景播放，还可以为将一个多媒体采集源所采集的多媒体流在显示屏上以分割为多个画面的形式进行播放，还可以是将多个多媒体采集源所采集的多媒体流在显示屏上的不同的显示单元处进行同步播放。
本申请所提供的多媒体上墙方法应用于一种多媒体上墙系统，图1为一种多媒体上墙系统的结构示意图，如图1所示，该多媒体上墙系统包括：显示屏1、监控平台2、客户端3、流媒体服务器4以及解码器5；其中，显示屏1用于将多媒体流以预设的显示方式进行显示；监控平台2用于管理系统中的多媒体采集源(例如摄像头)，并与客户端3进行交互以处理客户端3发起的业务请求；客户端3用于为用户提供视频浏览、回放功能，以及与监控平台2进行业务交互，特别地，本申请中的客户端3具有多媒体上墙控制功能，能够对待上墙的多媒体流进行基于预设显示方式的处理；流媒体服务器4用于存储多媒体采集源所采集到的多媒体流，并实现多媒体流的转发功能；解码器5用于对经编码的多媒体流进行解码，并将解码后的多媒体流发送至显示屏1进行显示。
图2为本申请实施例所提供的一种多媒体上墙方法的流程图，该方法基于图1所示的多媒体上墙系统中的客户端3实现，如图2所示，该方法包括：
步骤S101、基于预先获取到的播放地址，从流媒体服务器中获取目标多媒体流采集源所采集的原始多媒体流。
播放地址是获取目标多媒体流采集源所采集的多媒体流的入口，播放地址由流媒体服务器确定出，播放地址可以为目标多媒体流采集源的地址(例如摄像头地址)，也可以是流媒体服务器中存储目标多媒体流采集源所采集的多媒体流的存储地址，例如，在实际应用中，当上墙的多媒体流为目标多媒体流采集源所采集的实时多媒体流时(例如，实时播放监控视频)，则播放地址为目标多媒体流采集源的地址(例如监控摄像头地址)， 当上墙的多媒体流为目标多媒体流采集源所采集的历史多媒体流时，此时播放地址为流媒体服务器中存储目标多媒体流采集源所采集的多媒体流的存储地址。
步骤S102、基于预先配置的多媒体上墙显示方式对原始多媒体流进行处理，得到已处理多媒体流。
在一些实施例中，待上墙多媒体流在进行上墙显示之前，用户可在客户端上对待上墙多媒体流的上墙显示方式进行配置，例如，画面融合显示方式或画面分割显示方式；客户端在从流媒体服务器中获取到目标多媒体流采集源所采集的原始多媒体流后，基于用户配置的上墙显示方式确定出对原始多媒体流的处理方式，进而基于该处理方式对原始多媒体流进行处理，以得到已处理多媒体流，所得到的已处理多媒体流后续在显示屏上进行显示时，将以用户所配置的上墙显示方式进行显示。
需要说明的是，基于用户所配置的上墙显示方式确定出对多媒体流的处理方式，以及基于所确定出的处理方式来对多媒体流进行处理已是现有技术中成熟的技术手段，本申请实施例不再赘述。
步骤S103、基于预先获取到的媒体接收地址，将已处理多媒体流发送至流媒体服务器，以供流媒体服务器将已处理多媒体流发送至显示屏，实现上墙显示。
媒体接收地址是指流媒体服务器接收已处理多媒体流的地址，客户端基于该媒体接收地址将已处理多媒体流发送至流媒体服务器，流媒体服务器在接收到已处理多媒体流后，将该已处理多媒体流发送至显示屏上，实现上墙显示。
需要说明的是，在一些实施例中，通常流媒体服务器先将已处理多媒体流发送至解码器进行解码，进而由解码器将解码后的多媒体流发送至显示屏进行显示，但在另外一些实施例中，也可将解码器的功能直接集成于流媒体服务器中，从而在流媒体服务器内直接完成对已处理多媒体流的解码，本申请并不对解码器的有无以及设置位置进行限定，只要已处理多媒体流能够在显示屏上进行正常显示即可。
本申请实施例所提供的多媒体上墙方法，客户端从流媒体服务器中获取待上墙的媒体流，并直接对待上墙的媒体流进行上墙显示方式的设 置，相较于现有技术，本申请所提供的多媒体上墙方法无需额外设置拼接控制器来对多媒体流的显示方式进行设置，从而降低了整个多媒体上墙系统的建设成本，并且，用户可在客户端上直接对待上墙媒体流的上墙显示方式进行设置，从而无需在拼接控制控制器的专有管理台上进行设置，进而使上墙显示方式的配置过程更便捷。
图3为本申请实施例提供的另一种多媒体上墙方法的流程图，如图3所示，在一些实施例中，在步骤S101之前，还包括：
步骤S100a、确定待上墙的目标多媒体流采集源以及多媒体上墙显示方式。
当用户需要将目标多媒体流采集源所采集的多媒体流进行上墙显示时，预先在终端内设置该目标多媒体流采集源所采集的多媒体流的上墙显示方式，以便于客户端基于用户所设置的上墙显示方式对多媒体流进行处理。
在一些实施例中，多媒体上墙显示方式包括：画面融合显示方式、画面分割显示方式或画面特效处理。
画面融合显示方式是指将至少一个多媒体流采集源的显示画面融合在指定分辨率的图像的指定位置(得到一副完整显示画面)。
画面分割显示方式是指将一个多媒体流采集源的显示画面分割为多个子画面进行显示，例如，将一个摄像头的画面分割为4个画面。
画面特效处理包括对画面的文字、图片或标注等的修改设置，例如，新增或修改叠加的文字内容、大小、字体、位置或动态显示效果，新增或修改叠加图片或标注，以及还包括对像素的调整。
图4为本申请实施例提供的又一种多媒体上墙方法的流程图，如图4所示，在一些实施例中，在步骤S101和步骤S100a之间，还包括：
步骤S100b、向监控平台发送多媒体上墙请求。
多媒体上墙请求中包括目标多媒体流采集源的身份信息和请求上墙的路数，其中，目标多媒体流采集源的身份信息可以为多媒体采集源的标识信息，请求上墙的路数是指多媒体采集源所具有的至少一路的采集点中，需要上墙显示的采集点的数量，例如，1路、4路等。
步骤S100c、接收监控平台反馈的媒体接收地址。
监控平台在接收到多媒体上墙请求后，向客户端反馈媒体接收地址，其中，媒体接收地址是指流媒体服务器接收多媒体流的地址，媒体接收地址可由监控平台在接收到多媒体上墙请求后，向流媒体服务器请求获取，并且，具体媒体接收地址的数量根据多媒体上墙请求中请求上墙的路数确定，即，当请求上墙的路数为1路时，媒体接收地址为1个，当请求上墙的路数为4路时，媒体接收地址为4个。
步骤S100d、向监控平台请求目标多媒体流采集源所采集的原始多媒体流在流媒体服务器中的播放地址。
本申请实施例中，客户端所获取的用于向流媒体服务器获取多媒体流的播放地址可由客户端向监控平台请求，具体地，客户端向监控平台发送播放地址获取请求，该播放地址获取请求中包含有目标多媒体流采集源的标识信息，监控平台在接收到该播放地址获取请求后，基于目标多媒体流采集源的标识信息，从自身数据库中查询出目标多媒体流采集源所采集的多媒体流的播放地址，并反馈给客户端。
图5为本申请实施例提供的再一种多媒体上墙方法的流程图，本申请实施例所提供的方法的执行主体为图1所示多媒体上墙系统中的监控平台2，如图5所示，该方法包括：
步骤S201、响应于客户端发送的多媒体上墙请求，向客户端反馈媒体接收地址，以供客户端基于媒体接收地址能够将已处理多媒体流发送至流媒体服务器。
该步骤同步骤S100c对应，具体请参见步骤S100c的描述，此处不再赘述。
步骤S202、向客户端发送播放地址，以供客户端基于播放地址能够从流媒体服务器中获取目标多媒体流采集源所采集的原始多媒体流并对所述原始多媒体流进行处理。
监控平台响应于客户端发送的获取请求目标多媒体流采集源所采集的原始多媒体流的播放地址的请求，而向客户端反馈目标多媒体流采集源所采集的原始多媒体流的播放地址，其中，播放地址的描述同步骤S101相同，此处不再赘述。
本申请实施例所提供的多媒体上墙方法，监控平台响应于客户端的 请求，而向客户端反馈待上墙的多媒体流的播放地址，从而使客户端能够基于播放地址从流媒体服务器中获取目标多媒体流采集源所采集的原始多媒体流并对所述原始多媒体流进行处理，相较于现有技术，本申请实施例无需额外设置拼接控制器来对多媒体流的显示方式进行设置，从而降低了整个多媒体上墙系统的建设成本，并且，用户可在客户端上直接对待上墙媒体流的上墙显示方式进行设置，从而无需在拼接控制控制器的专有管理台上进行设置，进而使上墙显示方式的配置过程更便捷。
在一些实施例中，如图6所示，在步骤S201之前，还包括：
步骤S200、向流媒体服务器请求媒体传输地址。
媒体传输地址是指流媒体服务器传输多媒体流的地址，媒体传输地址包括：媒体接收地址，媒体接收地址用于流媒体服务器接收多媒体流。
在一些实施例中，媒体传输地址还包括：媒体发送地址；媒体发送地址用于流媒体服务器发送多媒体流，此时，在执行步骤S201的同时，还包括：
步骤S201’、向解码器反馈媒体发送地址。
解码器在接收到媒体发送地址后，能够根据该多媒体发送地址识别出流媒体服务器发送来的已处理多媒体流，进而对已处理多媒体流进行解码，以进行上墙显示。
需要说明的是，本申请中，媒体接收地址和媒体发送地址可以为IP地址、端口号或RTSP URL地址，具体的，若解码器支持SIP或类似协议，则媒体接收地址和媒体发送地址为IP地址或端口号，若解码器支持RTSP协议，则媒体接收地址和媒体发送地址为RTSP URL地址。
