具体实施方式detailed description
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，本领域普通技术人员在没有做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。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本发明的申请人发现，视频直播业务中，当客户端的数量增多时，需要额外增加转码服务器或者分发服务器来满足客户端数量增多的需求，比如在转码服务器的带宽不够的情况下，需要增加转码服务器；而增加转码服务器时，由于转码服务器和分发服务器之间的耦合，将新增加的转码服务器添加至直播业务中的工作量大；然而借助分布式存储模块可以很好的解决这一问题。The applicant of the present invention found that in the live video service, when the number of clients increases, additional transcoding servers or distribution servers need to be added to meet the increasing demand of clients. For example, when the bandwidth of the transcoding server is insufficient, it is necessary to Increase the transcoding server; when adding the transcoding server, due to the coupling between the transcoding server and the distribution server, the workload of adding the newly added transcoding server to the live broadcast service is heavy; however, the distributed storage module can be used to to solve this problem.

由于分布式存储模块具有即写即读的功能，可以无间隔的接收视频及将接收的视频发送出去，所以可以满足直播业务视频写入不丢帧和直播不卡顿的需求。此外，由于分布式存储模块的带宽一般比转码服务器的带宽大，其可以为更多的客户端提供直播业务和回看业务；而且在客户端数量较多的时候，可以只对分布式存储单元进行改进升级，而不对转码服务器和分发服务器做改动，比如在分布式存储模块与转码服务器及分发服务器连接关系不变时，仅仅将分布式存储模块的网卡进行升级，比如扩大网卡的带宽等；实际应用中，还可以通过交换机将分布式存储模块与转码服务和分发服务器连接，这样，在需要更换分布式存储模块时，借助交换机可以很方便的实现分布式存储模块的更换。Since the distributed storage module has the function of writing and reading immediately, it can receive video without interval and send the received video, so it can meet the requirements of live broadcast business video writing without frame loss and live broadcast without freezing. In addition, because the bandwidth of the distributed storage module is generally larger than that of the transcoding server, it can provide live broadcast services and playback services for more clients; and when the number of clients is large, only distributed storage modules can The unit is improved and upgraded without changing the transcoding server and distribution server. For example, when the connection relationship between the distributed storage module and the transcoding server and distribution server remains unchanged, only the network card of the distributed storage module is upgraded, such as expanding the network card. Bandwidth, etc.; in practical applications, the distributed storage module can also be connected to the transcoding service and distribution server through the switch, so that when the distributed storage module needs to be replaced, the distributed storage module can be easily replaced by the switch.

分布式内存单元将分布式文件单元挂载至自身的本地目录，将接收的视频拷贝至分布式文件单元对应的挂载目录，挂载目录为挂载分布式内存单元的本地目录，同时建立拷贝的视频与挂载目录间的对应关系，以供第二分发服务器基于挂载目录及对应关系在分布式文件单元中读取对应的视频。The distributed memory unit mounts the distributed file unit to its own local directory, and copies the received video to the mounting directory corresponding to the distributed file unit. The mounting directory is the local directory where the distributed memory unit is mounted, and a copy is created at the same time The corresponding relationship between the video and the mounted directory is used for the second distribution server to read the corresponding video in the distributed file unit based on the mounted directory and the corresponding relationship.
本发明实施例提供的一种视频直播方法中，分布式内存单元建立拷贝的视频与挂载目录间的对应关系之后，还可以包括：In a video live broadcast method provided by an embodiment of the present invention, after the distributed memory unit establishes the corresponding relationship between the copied video and the mounted directory, it may further include:
日志模块记录分布式内存单元拷贝的视频、挂载目录及对应关系，并生成日志。The log module records the video copied by the distributed memory unit, the mounted directory and the corresponding relationship, and generates a log.
本发明实施例提供的一种视频直播方法中，分布式内存单元将接收的视频拷贝至分布式文件单元对应的挂载目录，可以包括：In a video live broadcast method provided by an embodiment of the present invention, the distributed memory unit copies the received video to the mounting directory corresponding to the distributed file unit, which may include:
视频转存软件在分布式内存单元的触发下，将分布式内存单元接收的视频拷贝至分布式文件单元对应的挂载目录。Under the trigger of the distributed memory unit, the video dump software copies the video received by the distributed memory unit to the mount directory corresponding to the distributed file unit.
