例如, 当用户希望同时浏览两个会场的历史画面时, 在输入的回 放请求消息中选定这两个会场的流媒体标识信息, 并且选定需要的播 放位置信息, 当录播服务器得到该回放请求消息之后, 根据其所携带 的流媒体标识信息找到相应的两个会场的视频, 并根据播放位置信息 提取到从相应时间点开始的视频, 将选择到的这样两路流媒体信息组 合成为一路组合码流发送至发出请求的用户终端。
S104、 用户终端显示输出接收到的组合码流包括的流媒体信息。 其中, 流媒体信息具体可以包括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。

相应的, 本发明实施例提供的视频会议录播方法, 涉及录播服务 器, 如图 2所示, 包括:
S201、 录播服务器获取回放请求消息。
具体的, 录播服务器可以接收至少一个用户终端发送的回放请求 消息, 或者, 当录播服务器具有显示区域时, 录播服务器可以获取用 户在录播服务器显示区域输入的回放请求消息, 该录播服务器显示区 域包括至少一个子画面, 每一个子画面用于显示输出一个会场的实时 图像。 其中, 录播服务器获取用户在录播服务器显示区域输入的回放 请求消息的过程可以参照用户终端接收用户输入的回放请求消息的过 程。
S202、 录播服务器根据该回放请求消息选择流媒体信息。
其中, 回放请求消息可以包括流媒体标识信息和播放位置信息, 其中, 流媒体标识信息还可以包括参会会场的会场标识信息或该参会 会场所对应的子画面标志信息。 具体的, 录播服务器可以根据该流媒 体标识信息选择需要进行回放的会场并根据该播放位置信息从录制的 该会场的流媒体信息中选择需要进行回放的流媒体信息。 例如, 录播 服务器可以根据流媒体标识信息选定需要进行录播回放的会场画面, 同时, 录播服务器可以根据播放位置信息确定需要进行录播回放的历 史画面的起始时点。
5203、 录播服务器将选择到的至少一路流媒体信息组合成一路组 合码流, 一路流媒体信息对应一个会场。
5204、 录播服务器向至少一个用户终端发送该组合码流。
其中, 流媒体信息具体可以包括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。
本发明实施例提供的视频会议录播的方法, 通过接收用户输入的 回放请求消息, 并将该回放请求消息发送至录播服务器, 录播服务器 可以根据回放请求消息选择流媒体信息, 用户终端在接收到录播服务 器发送的一路组合码流后, 显示输出接收到的该至少一路流媒体信息, 其中, 该组合码流包括至少一路流媒体信息, 一路流媒体信息对应一 个会场。 采用这样一种方法对视频会议进行录播回放, 可以实现在视 频会议进行的中途, 根据用户的需要对会议的视频进行录播回放, 从 而提高了用户的使用感受。
进一步地, 本发明实施例视频会议录播方法, 如图 3所示, 包括:
5301、 录播服务器接收流媒体标识信息。
具体的, 用户可以在视频会议开始之前, 根据历史经验或预计参 加视频会议的会场数在录播服务器上预设一组流媒体标识信息以便录 播服务器实时监控记录有流媒体标识信息的至少一个用户终端。 或者 当用户终端接入会议网络后, 录播服务器将自动生成网络拓朴, 得到 所有会场的流媒体标识信息。 录播服务器同时可以根据该流媒体标识 信息配置录制策略, 例如, 录播服务器可以选择录制记录有流媒体标 识信息的全部用户终端的会议视频。
5302、 录播服务器将该流媒体标识信息发送至至少一个用户终端。 例如, 若该流媒体标识信息分别包括会场 1 至会场 9的流媒体标 识信息, 当用户终端接收到该流媒体标识信息后, 用户终端的显示区 域中分别对应会场 1 至会场 9 的子画面将处于开启状态。 这样一来, 用户终端可以方便快速地了解到所有参会的会场信息, 快速地与录播 服务器建立连接, 从而使得用户终端可以根据流媒体标识信息从所有 参会的会场中选择需要进行回放的会场的流媒体信息。
5303、 当会场状态发生变化时, 用户终端向录播服务器发送会议 信息, 以便该录播服务器更新流媒体标识信息。
其中, 该会议信息可以用于指示当前会场是否参与会议, 或者还 可以用于指示当前会场所能够提供的全部流媒体。
例如, 若视频会议初始时刻的用户终端分别包括会场 1 至会场 9 的用户终端, 在会议的进行途中, 会场 9 的用户离开会议, 该会场的 用户终端断开了与各个会场的连接, 该用户终端同时将向录播服务器 发送会议信息, 该会议信息中指示会场 9 的用户终端已断开, 或者, 当会场 9 的用户离开会议一段时间后又重新加入, 当会场 9的用户终 端重新接入网络时, 该用户终端同样将向录播服务器发送会议信息, 该会议信息中指示会场 9 的用户终端已连接, 该录播服务器可以根据 该会议信息更新流媒体标识信息。 这样一来, 可以避免已断开的用户 终端继续占用录播服务器的资源。
5304、 用户终端采集用户所在会场的图像和声音, 得到流媒体信 息。
例如, 用户终端可以通过摄像头采集得到用户所在会场的图像信 息, 通过麦克风采集得到用户所述会场的声音信息, 将该图像信息与 该声音信息按照相同时间叠加在一起即形成了该会场的流媒体信息。
5305、 录播服务器接收并保存至少一个用户终端发送的流媒体信 其中, 流媒体信息具体可以包括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。
S306、 录播服务器获取回放请求消息。
具体的, 录播服务器可以接收至少一个用户终端发送的回放请求 消息, 或者, 当录播服务器具有显示区域时, 录播服务器可以获取用 户在录播服务器显示区域输入的回放请求消息, 该录播服务器显示区 域包括至少一个子画面, 每一个子画面用于显示输出一个会场的实时 图像。 需要说明的是, 对于具有显示区域的录播服务器而言, 录播服务 器可以根据从用户终端处获取的回放请求消息选择流媒体信息, 并将 选择到的流媒体信息返回给发出请求的用户终端或在录播服务器的显 示区域进行回放; 或者, 录播服务器还可以根据用户终端在录播服务 器的显示区域输入的回放请求消息选择流媒体信息, 并将选择到的流 媒体信息发送至制定的用户终端或在录播服务器的显示区域进行回 放。 其中, 录播服务器获取用户在录播服务器显示区域输入的回放请 求消息的过程可以参照用户终端接收用户输入的回放请求消息的过 程。
当录播服务器接收的是来自用户终端发送的回放请求消息时, 该 回放请求消息可以包括流媒体标识信息和播放位置信息, 该流媒体标 识信息还可以包括参会会场的会场标识信息或该参会会场所对应的子 画面标志信息。 回放请求消息中的流媒体标识信息可以是用户从用户 终端获得的流媒体标识信息中选择的, 与需要进行回放的会场所对应 的流媒体标识信息, 录播服务器可以根据该流媒体标识信息选择需要 进行回放的会场并根据该播放位置信息从录制的该会场的流媒体信息 中选择需要进行回放的流媒体信息。
S307、 录播服务器根据该回放请求消息选择流媒体信息。
S308、 录播服务器将选择到的至少一路流媒体信息组合成一路组 合码流, 一路流媒体信息对应一个会场。
其中, 具有码流组合功能的录播服务器可以通过自身的码流组合 模块进行码流组合; 或者录播服务器还可以将选择到的至少一路流媒 体信息发送至会议 MCU ( multipoint control unit , 多点控制单元) , 该 会议 MCU可以将至少一路流媒体信息组合为一路码流。
具体的, 可以采用如下方法将多路流媒体信息组合得到一路组合 码流: 当录播服务器选择到至少一路流媒体信息之后调用码流组合资 源; 将需要进行组合的多路流媒体信息切换发送至各个子流进行解码 生成流媒体信息的解码信息; 将各个子流的解码信息组合成一路统一 的组合码流, 并对该组合码流进行编码。
例如, 当录播服务器根据用户输入的回放请求消息选择到多路流 媒体信息时, 将触发录播服务器的组合子系统, 该组合子系统将向组 合控制模块下发合成命令。
组合控制模块对该合成命令进行分析, 并调用组合资源管理模块, 分配处理资源。 如果组合资源管理模块没有足够的资源可以进行码流 组合, 则组合控制模块将向组合子系统上报资源不足的错误; 如果组 合资源管理模块有充足的资源, 则组合控制模块调用资源。
在调用到资源之后, 组合控制模块将向录播服务器中用于完成码 流组合的相关处理装置的流处理控制模块下发流编码器、 流解码器调 度命令。 相关处理装置的流处理控制模块收到流编码器、 流解码器调 度命令后, 将这些调度命令分别转发至流编码模块与流解码模块, 从 而调度起相应的编码器和解码器。
组合控制模块向流交换模块发送指令, 指示其将需要进行组合的 多路流媒体信息切换发送至组合码流的各个子流的流解码器所在的流 处理模块上。 例如, 可以将需要进行组合的多路流媒体信息切换发送 至视频组合画面的子画面流的解码器所在的流处理模块上。
组合码流的各个子流的流解码器所在的流处理模块将收到的流媒 体信息分发到流解码模块。 该流解码模块对流媒体信息码流进行解码 生成流媒体信息的解码信息 (例如, 视频信息的解码信息即为解码后 的图像, 音频信息的解码信息即为解码后的音频数据) , 然后将解码 后的流媒体信息发送到对应的流处理模块。
组合码流的各个子流的流解码器所在的流处理模块会将接收到的 解码后的流媒体信息发送至组合码流的编码器所在的流处理模块。 该 流处理模块会将该解码后的流媒体信息分发到组合码流的流编码模 块, 并将各个子流的数据组合成一路统一的组合码流, 并对该组合码 流进行编码。
统一编码后的组合码流存储在录播服务器的内部, 以便该录播服 务器显示输出或向用户终端发送该组合码流信息。
这样一种组合码流中可以包括用户点播的多路流媒体信息, 对于 视频会议而言, 可以在带宽不变的前提下实现多会场音视频信息的录 播回放。 S309、 录播服务器显示输出选择到的至少一路流媒体信息。
具体的, 当流媒体标识信息包括第一子画面标志信息或第一子画 面对应的第一会场的会场标识信息时, 在该录播服务器显示区域的第 一子画面显示输出选择到的与该第一子画面标志信息或该第一会场的 会场标识信息对应的第一流媒体信息; 或当该流媒体标识信息为第一 子画面标志信息或第一子画面对应的第一会场的会场标识信息时, 在 显示区域显示输出选择到的与该第一子画面标志信息或该第一会场的 会场标识信息对应的第一流媒体信息; 或当该流媒体标识信息包括第 一子画面标志信息或第一子画面对应的第一会场的会场标识信息以及 第二子画面标志信息或第二子画面对应的第二会场的会场标识信息 时, 在该录播服务器显示区域的第一子画面显示输出选择到的与该第 一子画面标志信息或该第一会场的会场标识信息对应的第一流媒体信 息, 同时在该录播服务器显示区域的第二子画面同步显示输出选择到 的与该第二子画面标志信息或该第二会场的会场标识信息对应的第二 流媒体信息。
例如, 当录播服务器自身具有音视频输出设备时, 该录播服务器 可以直接播放选择到的至少一路流媒体信息。 或者, 用户也可以通过 录播服务器的数据接口将至少一路流媒体信息拷贝或者发送至用户的 其他私有设备。
S310、 用户终端接收该录播服务器发送的一路组合码流, 该组合 码流包括至少一路选择到的流媒体信息, 一路流媒体信息对应一个会 场。
S311、 用户终端显示输出接收到的至少一路流媒体信息。
具体的, 当流媒体标识信息包括第一子画面标志信息或第一子画 面对应的第一会场的会场标识信息时, 在该用户终端显示区域的第一 子画面显示输出接收到的与该第一子画面标志信息或该第一会场的会 场标识信息对应的第一流媒体信息; 或当该流媒体标识信息为第一子 画面标志信息或第一子画面对应的第一会场的会场标识信息时, 在该 用户终端显示区域显示输出接收到的与该第一子画面标志信息或该第 一会场的会场标识信息对应的第一流媒体信息; 或当该流媒体标识信 息包括第一子画面标志信息或第一子画面对应的第一会场的会场标识 信息以及第二子画面标志信息或第二子画面对应的第二会场的会场标 识信息时, 在该用户终端显示区域的第一子画面显示输出接收到的与 该第一子画面标志信息或该第一会场的会场标识信息对应的第一流媒 体信息, 同时在该用户终端显示区域的第二子画面同步显示输出接收 到的与该第二子画面标志信息或该第二会场的会场标识信息对应的第 二流媒体信息。

在多个用户终端实际进行视频会议的过程中, 每个用户终端的显 示屏的子画面可以分别显示出其他会场的用户终端所拍摄的实时视 频。 每个子画面均具有表示时间进度的进度条, 进度条所处的位置即 为当前的数据位置, 用户可以通过操作进度条请求录播服务器录播回 放历史视频信息。
例如, 当参与视频会议的用户终端仅包括本地以及位于另一远程 会场的两个用户终端时, 本地用户终端的显示屏上仅显示另一会场的 画面。 如图 4 所示, 本地用户终端显示屏的显示画面为另一会场的实 时画面, 画面下方具有显示时间的进度条, 进度条所处位置为当前时 间点。
当用户希望浏览另一会场的历史视频画面时, 可以将进度条向左 拖动至希望浏览的历史时刻, 本地用户终端从而确定用户输入了回放 请求消息。
本地用户终端将该请求消息发送至录播服务器, 录播服务器根据 该请求消息选择存储在录播服务器中相应的流媒体信息, 并将选择到 的该历史视频画面进行适配处理发送至本地用户终端。
本地用户终端将接收到的流媒体信息进行解码并显示输出于本地 用户终端的显示屏上。 其中, 流媒体信息可以包括视频信息、 音频信 息、 图片信息、 字幕信息中的至少一种, 例如, 当用户拖动进度条浏 览另一会场的历史视频画面时, 声音和字幕也将跟随用户的拖动进行 回放。
再例如, 当参与视频会议的用户终端包括分处多个会场的用户终 端时, 如图 5所示, 本地用户终端的显示屏划分为 9个不同的显示子 画面, 分别显示会场 1 至会场 9的实时画面。 每个子画面的下方均具 有显示每个子画面时间的进度条, 整体画面的下方还具有显示整体时 间的全局进度条。
当用户希望浏览其他所有会场的历史视频画面时, 可以将全局进 度条向左拖动至希望浏览的历史时刻, 本地用户终端从而确定用户输 入了回放请求消息。
本地用户终端将该请求消息发送至录播服务器, 录播服务器根据 该请求消息选择存储在录播服务器中相应的多路流媒体信息, 录播服 务器可以将多路流媒体信息组合为一路组合码流并发送至本地用户终 端。
本地用户终端将接收到的组合码流进行解码并显示输出于本地用 户终端的显示屏上, 每个子画面均显示对应会场的同一历史时刻的历 史画面, 如图 6 所示, 当用户向左拖动全局进度条时, 所有子画面的 进度条统一跟随全局进度条的移动而移动。 其中, 流媒体信息可以包 括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。
或者, 当用户希望浏览其他会场中的某一特定会场的历史视频画 面时, 可以将该会场所对应子画面的进度条向左拖动至希望浏览的历 史时刻, 本地用户终端从而确定用户输入了回放请求消息。 以图 5 为 例, 当用户希望浏览会场 6 的历史视频画面时, 可以将画面 6 的进度 条向左拖动。
本地用户终端将该请求消息发送至录播服务器, 录播服务器根据 该请求消息选择存储在录播服务器中相应的多路流媒体信息, 录播服 务器可以将多路流媒体信息组合为一路组合码流并发送至本地用户终 端。 在该组合码流中, 子画面 6 已配置为用户请求的会场 6的历史视 频画面, 其他会场所对应的子画面未 #文更改。
本地用户终端显示屏的显示画面可以如图 7 , 其中, 流媒体信息可 以包括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。 子 画面 6的进度条位于用户选择的历史时刻, 子画面 6显示会场 6的历 史画面, 其他子画面未发生变化。 用户还可以将子画面 6 放大至全屏 播放, 如图 7所示, 这样一来可以进一步提高用户的使用感受。
再或者, 当用户希望浏览其他会场中的多个特定会场的历史视频 的历史时刻; 或者用户还可以选定多个子画面进行画面联动, 当用户 拖动一个子画面的进度条时, 其他联动子画面的进度条也会跟随者移 动。 同样以图 5为例, 子画面 1与子画面 2为联动画面, 当用户希望 同时浏览会场 1、 会场 2的历史视频画面时, 可以将子画面 1或子画面 2的进度条向左拖动。
本地用户终端将该请求消息发送至录播服务器, 录播服务器根据 该请求消息选择存储在录播服务器中相应的多路流媒体信息, 录播服 务器可以将多路流媒体信息组合为一路组合码流并发送至本地用户终 端。 在该组合码流中, 子画面 1 和子画面 2 已配置为用户请求的历史 视频画面, 其他会场所对应的子画面未 #文更改。
本地用户终端显示屏的显示画面可以如图 8 , 其中, 流媒体信息可 以包括视频信息、 音频信息、 图片信息、 字幕信息中的至少一种。 子 画面 1和子画面 2的进度条位于用户选择的历史时刻, 分别显示会场 1 和会场 2的历史画面, 其他子画面未发生变化。
进一步地, 本地用户终端在接收到录播服务器发送的其他会场历 史视频画面的流媒体信息之后, 还可以将该流媒体信息转发至参与会 议的其他会场的用户终端, 以使其他会场也能够同时参阅该录播回放。
