视频云存储方法及系统、预览云存储的视频的方法及系统
本申请要求于2015年4月21日提交中国专利局、申请号为201510190857.9发明名称为“视频云存储方法及系统、预览云存储的视频的方法及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及视频云存储技术，尤其涉及一种视频云存储方法及系统、预览云存储的视频的方法及系统。
背景技术
视频云存储是在云计算概念上延伸和发展出来的一种通过集群应用、网格技术或分式文件系统等功能的一种系统，其通过应用软件集合起来协同工作，共同对外提供视频数据存储和业务访问功能。
目前的云存储系统，存储系统向前端设备(如网络摄像机)取流存储在存储设备中，平台也会向前端设备取流来进行预览。云存储设备和平台都是通过网络向前端设备取流。在实际应用场景中，经常会遇到前端IPC(IP camera，网络摄像机)由于网络带宽问题而只能输出一路视频流。如果网络异常或者前端设备只支持输出一路流，此时存储和预览就不可以同时进行，不能满足云存储系统的需求。
可以将前端IPC(网络摄像机)的流接入到外置流媒体中，平台预览和存储设备的存储都从该流媒体中进行取流存储。正常使用环境下，如图1所示，前端设备(如图1示出的网络摄像机)将数据流写入外置流媒体转发服务器，平台(图1示出IVMS-平台)通过流媒体转发服务器取数据流预览，云存储设备(如图1示出的存储设备)通过流媒体转发服务器取数据流存储。这样可以解决前端由于网络带宽问题只能出一路数据流带来的冲突。但是，这种方案的缺点也很明显，对于大规模存储系统，前端较多，就需要有大量的流媒体转发服务器来进行流媒体的转发，这就会使得整个系统的成本大幅攀升，且存在单点容易产生故障而无法继续作业的固有缺陷，比如某个流媒体转发服务器故障时，与其相连的前端设备就无法进行数据流的传输和存储。
如果从控制成本的角度出发而减少转发流媒体服务器的数量，则会出现大量前端设备接入少量转发服务器的架构，这又会使得转发服务器压力增大，从而导致取流速度受限。而且，外置的流媒体转发服务器在负载过高的情况下难以进行负载均衡，持续作业就容易宕机，再加上不可避免的服务器故障等原因，如图2所示，接入该服务器的前端设备(如图2示出的网络摄像机)视频流(如图2示出的数据流)就无法提取，会导致平台(如图2示出IVMS-平台)视频预览失败或者云存储数据(如图2示出的数据流)丢失等故障，整个视频云存储系统(图2示出存储设备)可靠性较差。

具体实施方式
以下将结合附图及实施例来详细说明本申请的实施方式，借此对本申请如何应用技术 手段来解决技术问题，并达成相应技术效果的实现过程能充分理解并据以实施。本申请实施例以及实施例中的各个特征，在不相冲突前提下可以相互结合，所形成的技术方案均在本申请的保护范围之内。
另外，附图所示出的本申请实施例的方法所包含的步骤，可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然本申请实施例的方法在所示的流程图中体现出了本申请的技术方案在执行时的一定的逻辑顺序，但通常而言，该逻辑顺序仅限于通过该流程图所示出的实施例。在本申请的另一些实施例中，本申请的技术方案的逻辑顺序也可以以不同于附图所示的方式来实现。
本申请实施例的视频云存储方法的实施例，主要用于云存储中的存储设备从前端设备进行取流并存储。如图3所示，该方法主要包括如下步骤。
步骤S310，云存储的管理服务器收到平台下发的录像计划后，确定目标存储设备，将该录像计划下发给指定的该目标存储设备，由该目标存储设备向与录像计划对应的前端设备(如网络摄像机)获取视频流。
本申请的实施例，在存储设备中内置有流媒体转发模块。存储设备中的内置流媒体转发模块，主要是向系统接入的前端设备取流，并将视频流转发到存储设备的存储模块进行存储，并提供给平台以便于在平台进行预览。
平台向管理服务器下发需要为前端IPC制定存储视频流(或者说数据流)的录像计划。管理服务器会根据当前云存储的系统运行情况以及预设的负载均衡策略，将平台下发的录像计划下发到指定的目标存储设备中的视频接入服务模块。存储设备接收到该录像计划之后，为该录像计划生成索引信息记录在本地，并将该索引信息发送给管理服务器，便于管理服务器根据该索引信息，能够顺利、准确地获知该存储设备在执行该录像计划。
通常而言，一台管理服务器都会对应多台存储设备，每个存储设备又都会执行或多或少的不同数量的录像计划。每一个录像计划都会对应一条索引信息，至少记录有存储设备的标识信息和链接地址。管理服务器根据存储在本地的索引信息，就可以准确获知每台存储设备当前正在执行哪些录像计划。
存储设备中的视频接入服务模块，根据该录像计划进行本地配置，生成相应的视频接入参数。由存储设备内置的流媒体转发模块根据该视频接入参数向前端设备取流，接收该前端设备所发送的视频流。流媒体转发模块所接收的视频流由存储设备中的存储模块进行本地存储。
步骤S320，当存储设备因故障等原因无法从前端设备取流时，向管理服务器发送告 警。管理服务器接收该存储设备无法从前端设备取流时发出的告警。
当存储设备内置流媒体转发模块出现异常导致无法从前端设备取流的时候，存储设备中的告警模块就会向管理服务器发送告警。
步骤S330，管理服务器根据存储设备所发送的告警，基于根据负载均衡策略将该录像计划下发给其他的存储设备，由其他的存储设备继续取该视频流。
管理服务器接收到告警后，还可以根据本地记录的索引信息，获得该异常的存储设备正在执行的所有录像计划，根据负载均衡策略将该异常的存储设备正在执行的所有录像计划下发到其他的存储设备中，并更新与这些录像计划相对应的索引信息，然后由其他存储设备中的内置流媒体转发模块继续取流并存储，这样就保证了前端设备所提供的视频数据不会丢失。
本发明的实施例提供了一种视频云存储系统，如图4所示，包括管理服务器410以及由管理服务器指定的目标存储设备420。
管理服务器410被设置为接收到平台下发的录像计划后，根据负载均衡策略，确定目标存储设备420，然后将该录像计划下发给该目标存储设备420。在收到目标存储设备420发出的告警后，根据负载均衡策略将录像计划下发给其他存储设备。
目标存储设备420被设置为根据管理服务器410下发的录像计划，从与该录像计划对应的前端设备获取视频流并存储。在无法从该前端设备获取视频流时，就向管理服务器410发出告警，将异常情况报告给管理服务器410。
如图4所示，本申请的实施例中，目标存储设备420包括视频接入服务模块421以及流媒体转发模块422。视频接入服务模块421，与管理服务器410相连，接收管理服务器410下发的录像计划，并根据所接收的录像计划生成视频接入参数。流媒体转发模块422，与视频接入服务模块421及前端设备相连，被设置为根据视频接入参数向前端设备获取视频流。
如图4所示，本申请的实施例中，该目标存储设备420还可以包括索引模块423，与管理服务器410相连，还与视频接入服务模块421或者其他用于接收该录像计划的模块相连，被设置为为录像计划生成索引信息，并将该索引信息发送给管理服务器410，或者通过其他能够与管理服务器进行通信的模块，将该索引信息发送给管理服务器。该索引信息至少包含有目标存储设备420的标识和地址。管理服务器410被设置为收到告警后，可以根据本地记录的索引信息以及负载均衡策略，将所述目标存储设备420正在执行的所有录像计划下发给其他存储设备。
在平台需要对云存储的视频进行预览时，如图5所示，本申请的预览云存储的视频的方法，主要包括如下步骤。
步骤S510，平台向流媒体客户端(VTDU-Client)发送预览请求。
步骤S520，流媒体客户端向管理服务器发送预览指令，该预览指令中包含有前端设备的标识(ID)信息。
步骤S530，收到该预览指令的管理服务器，根据该预览指令所包含的前端设备的标识信息，重定向到目前存储该前端设备所提供的视频流(或者说数据流)的存储设备，确定该存储设备的标识(ID)信息。
步骤S540，管理服务器向流媒体客户端发送重定向信息，该重定向信息中包含有该存储设备的ID信息。
步骤S550，流媒体客户端根据该存储设备的ID信息，向重定向的该存储设备发送取流指令。
步骤S560，收到取流指令的该存储设备，通过内置的流媒体转发模块向前端设备获取视频流。
步骤S570，该存储设备将从前端设备获取到的视频流转发到流媒体客户端，以便在平台上进行视频预览。
步骤S580，当存储设备出现异常导致无法从前端设备获取视频流，从而导致预览出现异常时，流媒体客户端会自动重连管理服务器中内置的流媒体重定向模块。管理服务器中的流媒体重定向模块根据该自动重连，将预览指令重定向到该继续存储该前端设备所提供的视频流的其他存储设备，从其他存储设备处继续获取视频流进行预览，来支持平台预览功能，保证平台的正常预览。
本申请实施例的预览云存储的视频的系统，如图6所示，包括流媒体客户端610、管理服务器620以及存储设备630。
流媒体客户端610，与平台600、管理服务器620及存储设备630相连，被设置为收到平台600发送的预览请求后向管理服务器620发送预览指令，预览指令中包含有前端设备640的标识信息；根据存储设备630的标识信息，向存储设备630发送取流指令；接收存储设备630发送的视频流并进行预览。
管理服务器620，被设置为接收预览指令，根据前端设备640的标识信息，重定向到目前存储前端设备640所提供的视频流的存储设备630，确定存储设备630的标识信息； 并向流媒体客户端610发送重定向信息，重定向信息中包含有存储设备630的标识信息。
存储设备630，被设置为根据取流指令，向前端设备640获取视频流并转发给流媒体客户端610。
本申请的实施例中，流媒体客户端610被设置为在预览异常时自动重连管理服务器620；管理服务器620被设置为根据自动重连将预览指令重定向到继续存储前端设备640提供的视频流的其他存储设备630，从其他存储设备630处继续获取视频流。
本申请实施例的视频流的云存储系统，还请同时参考本前述申请实施例视频流的云存储方法以及如图7所示的本申请实施例的视频云存储系统及预览云存储的视频的系统的原理架构示意图。
本申请的实施例，如图7所示，摄像机将数据流传输至视频云存储系统，在存储设备中内置流媒体转发模块(如图7示出的存储(内置流媒体转发模块))，并在管理服务器中内置流媒体重定向模块(对应如图7示出的1-信令和2-重定向信息)。存储设备中的内置流媒体转发模块，主要是向系统(如图7示出的视频云存储系统)接入的前端设备取数据流(对应如图7示出的3-取流信令)，并将视频流转发到存储设备进行存储和在平台(如图7所示的IVMS-平台(VTDU-客户端)，其中，VTDU的英文全拼为Video Transfer&Distribute Unit，中文名字为视频传送分发单元)进行预览(对应如图7示出的4-数据流)。
管理服务器中内置的重定向模块，主要是在存储设备中的流媒体转发模块取流异常的时候，根据预设策略将前端设备接入到其他存储设备的内置流媒体转发模块中，并记录相应的索引信息，便于持续为平台提供流预览。
本申请通过内置在存储设备中的流媒体转发模块和内置在管理服务器中的重定向模块的相互合作，可以保证前端设备只能出一路流的情况下实现存储和预览的并行，并保证存储和预览的正确性。且在某个存储设备中的流媒体异常时可以快速接管，保证数据不丢失，提高用户体验。
本申请的实施例可以接入大量的前端设备，能够并行实现高效的流存储和预览。在高并发取流和预览时，视频流存储和预览独立进行，互不影响，有效提高了系统性能。本申请的实施例基于负载均衡技术，当存储系统的内置流转发出现异常时，可以由其他存储设备中的流媒体转发模块接管，不会造成前端设备的数据流丢失。
本领域的技术人员应该明白，上述的本申请实施例所提供的装置的各组成部分，以及方法中的各步骤，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的 网络上。可选地，它们可以用计算装置可执行的程序代码来实现。从而，可以将它们存储在存储装置中由计算装置来执行，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本申请不限制于任何特定的硬件和软件结合。
虽然本申请所揭露的实施方式如上，但所述的内容仅为便于理解本申请技术方案而采用的实施方式，并非用以限定本申请。任何本申请所属领域内的技术人员，在不脱离本申请所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本申请的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
