为了更清楚地说明本公开实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍,显而易见地,下面描述中的附图是本公开的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
图1是现有技术提供的多媒体数据的处理系统的一种结构示意图;
图2是本公开实施例提供的向图1所示的处理系统添加处理节点之后的处理系统结构示意图;

图9是为本公开实施例提供的一种多媒体数据的处理装置的结构框图;
图10、图11是为本公开实施例提供的两种电子设备的结构框图。
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
本公开实施例可以应用于多媒体数据的处理系统中。数据处理系统可以包括顺序排列的多个处理节点,处理节点的数量可以根据实际应用场景设定。,每个处理节点用于对多媒体数据进行处理,不同处理节点的处理逻辑可以相同,也可以不同。相邻两个处理节点可以称为上游节点和下游节点,上游节点输出的多媒体数据是下游节点输入的多媒体数据,也就是说,上游节点对多媒体数据处理之后,再由下游节点对其进行处理。
图1是现有技术提供的多媒体数据的处理系统的一种结构示意图。参照图1所示,处理系统包括顺序排列的五个处理节点:ND1至ND5。其中,ND1是ND2的上游节点,ND2是ND1的下游节点,依次类推。从而,ND1对输入到处理系统的多媒体数据D1进行处理得到多媒体数据D2,ND1输出的多媒体数据D2输入到ND2中进行处理得到多媒体数据D3,ND2输出的多媒体数据D3输入到ND3中进行处理得到多媒体数据D4,ND3输出的多媒体数据D4输入到ND4中进行处理得到多媒体数据D5,ND4输出的多媒体数据D5输入到ND5中进行多媒体处理得到数据D6。如此,相当于将D1通过处理系统处理得到D6。
上述每个处理节点可以是开源多媒体处理框架提供的多媒体处理器,其中,开源多媒体处理框架可以例如为Ffmpeg、Gstreamer。当开源多媒体处理框架为Ffmpeg时,多媒体处理器可以是Ffmpeg提供的avfilter。
上述每个处理节点的功能可以不同。当上述ND1用于拉取视频流,ND2用于进行视频解码,ND3用于进行图像锐化,ND4用于合流布局,ND5用于解码时。
上述处理系统的结构可以变更,包括:向处理系统中添加节点、从处理系统中删除节点。
图2是本公开实施例提供的向图1所示的处理系统添加处理节点之后的处理系统结构示意图。参照图2所示,添加的处理节点包括ND6和ND7。ND6的上游节点为ND1,ND6的下游节点为ND7,ND7的下游节点为ND4。如此,ND6和ND7构成了一条新的处理线。新增的ND6和ND7的功能可以不同于图1中的各个处理节点的功能,也可以与图1中的部分节点的功能相同。例如,ND6用于进行解码,ND7用于进行图像分割。
图3是本公开实施例提供的从图2所示的处理系统中删除处理节点之后的处理系统结构示意图。参照图2和图3所示,被删除的处理节点包括:ND2和ND3。
现有技术中,相邻两个处理节点之间共用数据队列。也就是说,上游节点向该数据队列中写入数据的同时,下游节点从该数据队列中取数据。在这种情况下,下游节点待处理的数 据和正在处理的数据是不区分的,均在该数据队列中。从而,为了保证下游处理节点的处理过程不报错,在更新处理系统的结构之前,需要暂停上述处理系统中的各个处理节点的处理过程。在更新处理系统的结构之后,继续执行处理系统中的各个处理节点的处理过程。
可以看出,上述方案需要暂停处理系统,降低了处理系统的处理效率。
为了解决上述技术问题,本公开实施例可以在不需要暂停处理系统的前提下,更新处理系统的结构。考虑到需要暂停处理系统的原因是下游节点待处理的数据和正在处理的数据不区分,本公开实施例可以通过处理任务和下游节点的输入管理器,实现正在处理的数据和待处理的数据之间的解耦合。其中,处理任务中包括下游节点正在处理的数据,下游节点的输入管理器中包括下游节点待处理的数据。如此,更新处理系统的结构,不会影响处理任务的执行,从而实现了不暂停处理任务的情况下,更新处理系统的结构,提高了处理系统的处理效率。
下面以具体地实施例对本公开实施例的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本公开实施例进行描述。
与图1所示的处理系统相同,本公开实施例提供的处理系统也包括顺序排列的至少两个处理节点。但区别在于,本公开实施例中的每个处理节点对应有输入管理器和输出管理器,相邻两个处理节点分别为上游节点和下游节点,上游节点的输出管理器和下游节点的输入管理器具有关联关系,上游节点为下游节点生成多媒体数据。
图4是本公开实施例提供的多媒体数据的处理系统的一种结构示意图。参照图4所示,处理系统包括顺序排列的三个处理节点ND1至ND3。
其中,ND1和ND2为两个相邻处理节点,ND1是ND2的上游节点,ND2是ND1的下游节点。ND1的输出管理器OM1和ND2的输入管理器IM2具有关联关系。
ND2和ND3为两个相邻处理节点,ND2是ND3的上游节点,ND3是ND2的下游节点。ND2的输出管理器OM2和ND3的输入管理器IM3具有关联关系。
可以看出,第一个处理节点ND1的输入管理器IM1没有相关联的输出管理器。第一个处理节点通常可以为接收数据的节点,第一个处理节点可以按照时间周期启动,例如,每隔1分钟启动一次。
此外,最后一个处理节点ND3的输出管理器OM3没有相关联的输入管理器。最后一个处理节点通常没有输出数据,其通常用于将数据进行存储。
上述输入管理器用于存储处理节点的输入数据,输出管理器用于指示处理节点的输出数据输入到哪个输入管理器中,也就是用于指定该处理节点的下游节点。
图5是本公开实施例提供的一种多媒体数据的处理方法的步骤流程图。图5所示的方法可以应用在电子设备中,该电子设备可以理解为上述处理系统的调度器、或控制器、或引擎。参照图5所示,该多媒体数据的处理方法包括:
S101:在第一处理节点的第一输入管理器中存在第一多媒体数据时,生成第一处理任务,第一处理任务中包括所述第一多媒体数据。
其中,第一处理节点是上述图4所示的处理系统中的任一处理节点。第一输入管理器是第一处理节点的输入管理器,第一多媒体数据是第一处理节点待处理的多媒体数据,第一处理任务是第一处理节点的处理任务。一个处理节点可以对应一个或多个处理任务。
处理任务可以理解为一个存储任务信息的结构,其中可以包括以下至少一种信息:处理节点的标识信息、输入到处理节点的输入管理器中的多媒体数据、输出到处理节点的输出管理器中的多媒体数据、处理任务的生成时间。
图6是本公开实施例提供的处理任务的一种结构示意图。参照图6所示,输入队列中存储输入到处理节点的输入管理器中的多媒体数据,输出队列中存储输出到处理节点的输出管理器中的多媒体数据。
需要说明的是,在生成处理任务之后,输入队列中的多媒体数据可以理解为处理节点正在处理的多媒体数据,输出队列为空。在处理任务执行完成之后,输出队列中存储有多媒体数据。
S102:调用第一处理节点执行第一处理任务,得到第二多媒体数据,第二多媒体数据是对第一处理任务中的第一多媒体数据处理得到的数据。
其中,在第一处理任务执行完成时,第二多媒体数据存储于第一处理任务的输出队列中。
S103:将第二多媒体数据写入到至少一个第二处理节点的第二输入管理器中,第二输入管理器是与第一处理节点的第一输出管理器关联的输入管理器。
其中,第二处理节点是第一处理节点的下游节点。可以理解的是,一个第一处理节点可以对应有一个或多个下游节点。
在第一处理任务执行完成时,可以从第一处理任务的输出队列中提取出第二多媒体数据,并将第二多媒体数据写入到第二输入管理器中。
基于上述S101至S103的过程,图7是本公开实施例提供的对处理任务的调度过程示意图。
参照图7所示,对于第一个处理节点ND1,可以包括通过以下步骤进行调度:
S11:引擎从处理节点ND1的输入管理器IM1中取出多媒体数据D11。
S12:引擎根据D11生成ND1的处理任务TSK1,TSK1中包括D11、空的输出队列、ND1的标识信息、时间戳t1。
S13:引擎根据TSK1中的ND1的标识信息,调用ND1执行TSK1,得到的多媒体数据D12存储于TSK1中的输出队列中。
S14:在TSK1执行完成之后,引擎从TSK1的输出队列中取出D12。
S15:引擎根据TSK1中的ND1的标识信息,先确定ND1的输出管理器OM1,再确定与OM1关联的输入管理器IM2,并将D12写入到IM2中。
参照图7所示,对于第二个处理节点ND2,可以包括通过以下步骤进行调度:
S21:引擎从处理节点ND2的输入管理器IM2中取出多媒体数据D21。
S22:引擎根据D21生成ND2的处理任务TSK2,TSK2中包括D21、空的输出队列、ND2的标识信息、时间戳t2。
S23:引擎根据TSK2中的ND2的标识信息,调用ND2执行TSK2,得到的多媒体数据D22存储于TSK2中的输出队列中。
S24:在TSK2执行完成之后,引擎从TSK2的输出队列中取出D22。
S25:引擎根据TSK2中的ND2的标识信息,先确定ND2的输出管理器OM2,再确定与OM2关联的输入管理器IM3,并将D22写入到IM3中。
参照图7所示,对于第三个处理节点ND3,可以包括通过以下步骤进行调度:
S31:引擎从处理节点ND3的输入管理器IM3中取出多媒体数据D31。
S32:引擎根据D31生成ND3的处理任务TSK3,TSK2中包括D31、空的输出队列、ND3的标识信息、时间戳t3。
S33:引擎根据TSK3中的ND3的标识信息,调用ND3执行TSK3。
S34:引擎确定TSK3中的输出队列中不存在数据,代表ND3是最后一个处理节点。
需要说明的是,上述过程对于一个处理节点仅示出了一个处理任务。而在实际应用中,一个处理节点可以包括多个这样的处理任务,一个处理节点的不同处理任务中的处理节点的标识信息相同,但以下内容不同:输入队列中的多媒体数据、输出队列中的多媒体数据、时间戳。
基于上述处理系统,本公开实施例可以在不暂停处理系统的情况下,更新处理系统的结构。其中,更新处理系统的结构可以包括:删除第三处理节点、添加第四处理节点。第三处理节点是处理系统中待删除的任一处理节点。第四处理节点是待添加的任一处理节点。
下面详细说明从处理系统中删除第三处理节点的过程。
在本公开实施例中,删除第三处理节点的过程可以包括:首先,确定处理系统中待删除的第三处理节点、第三处理节点的第一相邻节点,第一相邻处理节点可以包括以下至少一种:第一上游节点、第一下游节点;然后,删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系,和/或,删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系。
当第三处理节点为处理系统中的第一个处理节点时,第三处理节点存在第一下游节点,但不存在第一上游节点。此时,只需要删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系。
当第三处理节点为处理系统中的最后一个处理节点时,第三处理节点存在第一上游节点,但不存在第一下游节点。此时,只需要删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系。
其中,第一上游节点是第三处理节点的上游节点,第一下游节点是第三处理节点的下游节点。
可以理解的是,处理系统中的节点是相互关联的,如果一个节点和其余节点不关联,则代表该处理节点被从处理系统中删除。从而本公开实施例可以通过删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系,以及删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系,实现删除第三处理节点的目的。
可以理解的是,当第三处理节点在处理系统中的位置不同时,删除第三处理节点之后处理系统的结构不同。
当第三处理节点是第一个处理节点或最后一个处理节点时,删除第三处理节点之后,处理系统中剩余的各个处理节点之间的关联关系未被破坏,通过上述关联关系仍构成一个完整的处理系统。此时,不需要对处理系统进行修复。
当第三处理节点是中间处理节点时,删除第三处理节点之后,第一上游节点和第一下游节点之间断开。此时,需要根据第一上游节点是否有下游节点,和/或,第一下游节点是否有上游节点,确定是否需要对处理系统进行修复。
当第一上游节点有下游节点,且,第一下游节点有上游节点时,不对处理系统进行修复。 如图8所示,当ND4为第三处理节点时,删除ND4之后,第一上游节点ND1具有下游节点ND2,第一下游节点ND2具有上游节点ND1。此时,可以不对处理系统进行修复。
当第一上游节点没有下游节点,和/或,第一下游节点没有上游节点时,对处理系统进行修复,也就是建立第一上游节点的输出管理器和第一下游节点的输入管理器之间的关联关系。这样,可以保证整个处理系统的链路是通的。如图8所示,当ND2为第三处理节点时,删除ND2之后,第一上游节点ND1和ND4均没有下游节点,第一下游节点ND3没有上游节点。此时,可以建立第一上游节点ND1的输出管理器OM1和第一下游节点ND3之间的输入管理器IM3之间的关联关系,并且建立第一上游节点ND4和第一下游节点ND3的输入管理器IM3之间的关联关系。
当然,在删除上述两种关联关系之后,还可以释放第三处理节点,以节约第三处理节点占用的计算机资源。
在删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系之前,可以在第一上游节点的输出管理器中设置第一标记,第一标记用于指示第一上游节点的处理任务停止对第三处理节点的输入管理器生成多媒体数据。
具体地,当第一上游节点的输入管理器与至少两个下游节点的输入管理器相关联时,仅对第三处理节点的输入管理器设置第一标记,其余下游节点的输入管理器不设置第一标记。如此,仅停止为第三处理节点生成数据的处理任务,不停止对其余下游节点生成数据的处理任务。这样可以使第一上游节点不会继续为第三处理节点生成数据,再等待已生成的存储在第三处理节点的输入管理器中的数据被第三处理节点处理完,即可删除第一上游节点的输出管理器和第三处理节点的输入管理器之间的关联关系。
可选地,在删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系之前,需要判断是否满足第一预设条件。如果满足第一预设条件,则删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系。如果不满足第一预设条件,则不删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系。
其中,上述第一预设条件可以包括以下至少一种:不存在目标处理任务、第三处理节点的输入管理器中不存在第四多媒体数据。目标处理任务是第一上游节点正在执行的处理任务,目标处理任务用于为第三处理节点的输入管理器生成多媒体数据。
上述第四多媒体数据是第三处理节点的输入管理器中的多媒体数据,也就是第三处理节点待处理的多媒体数据。
当第三处理节点为图4所示的处理系统中的ND2时,第一上游节点为ND1,第一下游节点为ND3。目标处理任务是ND1正在执行的,并且为ND2生成多媒体数据的处理任务。第三处理节点的输入管理器为IM2。
可以理解的是,第三处理节点的输入管理器中不存在第四多媒体数据,代表第三处理节点不存在待处理的多媒体数据。不存在目标处理任务代表不存在正在为第三处理节点生成待处理的多媒体数据的处理任务。在这种情况下,删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系,避免第四多媒体数据被丢弃和/或目标处理任务输出的多媒体数据被丢弃。进而避免多媒体数据在播放过程中缺失部分片段,有助于提高多媒体数据的播放平滑性。
当然,如果第三处理节点的输入管理器中存在第四多媒体数据时,首先,生成第二处理 任务,第二处理任务中包括第四多媒体数据;然后,删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系。
可以理解的是,在生成第二处理任务时,第四多媒体数据被装载到第二处理任务中,第三处理节点的输入管理器中不再存储第四多媒体数据。此时,可以删除第三处理节点的输入管理器和第一上游节点的输出管理器之间的关联关系。
需要说明的是,如果满足上述所有第一预设条件,则可以最大的保证多媒体数据的播放平滑性。
在生成第二处理任务之后,可以通过引擎调用第三处理节点执行第二处理任务,并在第二处理任务执行完成之后,释放第三处理节点占用的计算机资源。
相应地,在删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系之前,还需要判断是否满足第二预设条件。如果满足第二预设条件,则删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系。如果不满足第二预设条件,则不删除第三处理节点的输出管理器和第一下游节点的输入管理器之间的关联关系。
其中,上述第二预设条件可以包括:第三处理节点的输入管理器中不存在多媒体数据,和/或不存在第三处理节点正在运行的处理任务。代表第三处理节点不会为第二下游节点生成多媒体数据,从而,可以避免第三处理节点的输入管理器中的多媒体数据被处理完之后,或正在运行的处理任务被执行完之后,得到的多媒体数据没有输入管理器可输入,而导致处理完的数据被丢弃。进而避免多媒体数据在播放过程中缺失部分片段,有助于提高多媒体数据的播放平滑性。
下面详细说明向处理系统中添加第四处理节点的过程。
在本公开实施例中,添加第四处理节点的过程可以包括:首先,确定待添加的第四处理节点、第四处理节点的第二相邻节点,第二相邻节点包括第二上游节点和/或第二下游节点,第二上游节点和第二下游节点是处理系统中已有的处理节点;然后,建立第二上游节点的输出管理器和第四处理节点的输入管理器之间的关联关系,和/或,建立第四处理节点的输出管理器和第二下游节点的输入管理器之间的关联关系。
其中,第四处理节点是待添加的具有任意功能的处理节点,第四处理节点被添加到现有的处理系统中的第二上游节点和第二下游节点之间。第二上游节点和第二下游节点可以是相邻的两个处理节点,也可以是不相邻的两个处理节点。
基于图4所示的处理系统,图8是本公开实施例提供的一种添加第四处理节点之后的处理系统结构示意图。参照图8所示,ND4是第四处理节点,其第二上游节点为ND1,其第二下游节点为ND2。从而在添加ND4时,先建立第二上游节点ND1的输出管理器OM1和第四处理节点ND4的输入管理器IM4之间的关联关系,再建立第四处理节点ND4的输出管理器OM4和第二下游节点ND2的输入管理器IM2之间的关联关系。如此,实现了将第四处理节点ND4添加到图4所示的处理系统中ND1和ND2之间的目的,得到如图8所示的处理系统。
当然,在实际应用中,第四处理节点可以不存在第二上游节点或第二下游节点。
当第四处理节点被添加到图4所示的第一个处理节点ND1之前时,第四处理节点不存在第二上游节点,存在第二下游节点ND1。添加之后,第四处理节点是处理系统的新的第一个处理节点。
当第四处理节点被添加到图4所示的最后一个处理节点ND3之后时,第四处理节点不存 在第二下游节点,存在第二上游节点ND3。添加之后,第四处理节点是处理系统的新的最后一个处理节点。
可以看出,在添加第四处理节点时,处理系统中已有的各处理节点都不需要停止运行,也就是其处理任务均可以继续执行。
