其中，上述拆分服务器用于将源多媒体文件切成源切片媒体文件，并将原切片媒体文件发送给预处理设备与转码设备。
可选地，上述切片可以但不限于按照预定时长对源多媒体文件进行切片。例如，一个长10分50秒的源多媒体文件，从源多媒体文件的0分0秒处开始，每隔两分钟切片一次，将源多媒体文件切成5段两分钟的切片媒体文件和一段长50秒的切片媒体文件；或者按照平均分段的方法，将长10分50秒的源多媒体文件平均分成5段，每一段长2分10秒。
需要说明的是，上述按照预定时长或者平均分段的方法对源媒体文件进行切片仅仅为一种示例，具体对源文件切片的方法及切片媒体文件的时长本实施例在此不做限定。
可选地，在转码设备获取待处理的源多媒体文件中的源切片媒体文件 之前，控制设备还可以将源切片媒体文件对应的切片预处理任务发送给预处理设备，预处理设备根据预处理任务对源切片媒体文件所包含的帧画面进行关键区域识别，并保存识别得到的画面区域处理结果。

可选地，在从预处理设备集群中确定源切片媒体文件对应的预处理设备之前，还可以包括，控制设备根据切片媒体文件的文件类型，确定与文件类型对应的预处理设备。
例如，源切片文件的文件类型为包含字幕类型与不包含字幕类型，则选择对字幕进行处理的预处理设备对包含字幕的源切片文件进行处理，选择对视频进行处理的预处理设备对不包含字幕的源切片文件进行处理。
需要说明的是，上述从预处理设备集群中确定源切片媒体文件对应的预处理设备的方法仅为一种可选的示例，并不构成对本申请权利要求的限定。
可选地，转码设备根据画面区域处理结果对源切片媒体文件进行处理，得到处理后的目标切片媒体文件可以包括：转码设备根据画面区域处理结果获取源切片媒体文件包含的帧画面中的关键区域；转码设备对关键区域执行第一操作，对除关键区域外的其他区域执行第二操作。

可选地，关键时间段可以为源切片媒体文件中的一段或几段，第一操 作可以为提高码率，第二操作可以为降低码率。例如，画面区域处理结果中指示源切片媒体文件的第3秒到第7秒，第11秒到第14秒为关键时间段，其他时间段为非关键时间段，则可以将源切片文件中的第3秒到第7秒与第11秒到14秒的文件提高码率，其他非关键时间段的文件降低码率。
需要说明的是，上述第一操作为提高码率，第二操作为降低码率仅为一种可选的操作，本实施例对此不做具体限定。
通过本申请实施例，通过转码设备获取待处理的源多媒体文件中的源切片媒体文件，及与源切片媒体文件匹配的切片预处理结果，根据切片预处理结果中指示的存储地址获取与源切片媒体文件匹配的画面区域处理结果，并根据画面区域处理结果对源切片媒体文件进行处理的方法，通过为每一个源切片文件获得一个画面区域处理结果，从而可以根据画面区域处理结果对源多媒体文件中的每一个源切片媒体文件进行处理，得到目标切片媒体文件，实现了对源多媒体文件中的每一个切片媒体文件进行智能化分析并处理的目的。从而解决了相关技术中仅仅能够对整个源多媒体文件进行智能化分析的问题，提高了对源多媒体文件进行处理的处理效率。
作为一种可选的实施方案，在转码设备获取待处理的源多媒体文件中的源切片媒体文件之前，还包括：
S1，控制设备获取与源切片媒体文件对应的切片预处理任务；
S2，控制设备将与源切片媒体文件对应的切片预处理任务发送至预处理设备，以使预处理设备根据预处理任务对源切片媒体文件所包含的帧画面进行关键区域识别，并保存识别得到的画面区域处理结果。
可选地，上述切片预处理任务可以为对源切片媒体文件的每一帧中的画面进行分析，得到每一帧中的画面的关键区域，并将关键区域保存在画面区域处理结果中。
例如，结合图3进行说明。图3为一个源切片媒体文件中的一帧。如图3所示，源切片媒体文件长20分钟。在接收到源切片媒体文件与切片 预处理任务后，根据切片预处理任务，对源切片媒体文件中的每一帧进行分析，分析每一帧中的关键区域。图3中使用虚线框标识了关键区域。并将每一帧识别出的关键区域保存到画面区域处理结果中。
需要说明的是，对于确定关键区域的依据，本实施例不做具体限定。例如，可以通过源切片媒体文件中的图像的颜色、形状、特定图像等来确定关键区域，或者将带有字幕的区域确定为关键区域等。
通过本实施例，通过在获取待处理的源多媒体文件中的源切片媒体文件之前，获取与源切片媒体文件对应的切片预处理任务，并通过预处理设备对源切片文件中的帧画面进行关键区域识别，从而在对源切片文件进行处理的过程中，确定对源切片文件的处理策略，实现了对源切片媒体文件进行灵活处理的效果。
作为一种可选的实施方案，在将与源切片媒体文件对应的切片预处理任务发送至预处理设备之前，还包括：
S1，控制设备从预处理设备集群中确定出与源切片媒体文件对应的预处理设备，其中，源多媒体文件中的源切片媒体文件的数量与预处理设备集群中的预处理设备的数量之比为N：M，N为大于1的自然数，M为大于1的自然数。
可选地，上述源切片媒体文件的数量与预处理设备集群中的预处理设备的数量之比为N：M可以为一个源切片媒体文件对应一个预处理设备；或者多个源切片媒体文件对应一个预处理设备。
可选地，上述从预处理设备集群中确定源切片媒体文件对应的预处理设备可以为：将N个源切片媒体文件平均分配给M个预处理设备。
例如，结合图4进行说明，图4中显示有4个源切片媒体文件。当对4个源切片媒体文件进行分配时，按照顺序分配给预处理设备1与预处理设备2。即，将源切片媒体文件1分配给预处理设备1；将源切片媒体文件2分配给预处理设备2；将源切片媒体文件3分配给预处理设备1；将 源切片媒体文件4分配给预处理设备2。如果有源切片媒体文件5，则又分配给源切片媒体文件1。
需要说明的是，本实施例对源切片媒体文件的数量与预处理设备的数量不做具体限定。
可选地，上述从预处理设备集群中确定源切片媒体文件对应的预处理设备可以为：在分配每一个源切片媒体文件时，将该源切片媒体文件分配给当前源切片媒体文件最少的预处理设备。
例如，结合图5进行说明，预处理设备1中有源切片媒体文件1、3，预处理设备2中有源切片媒体2。当要分配源切片媒体文件4时，将源切片媒体文件4分配给源切片媒体文件少的预处理设备2。在分配源切片媒体文件5时，由于预处理设备1与预处理设备2中的源切片媒体文件数目一致，因此可以采用顺序分配或者随机分配的方法。
需要说明的是，本实施例对源切片媒体文件的数量与预处理设备的数量不做具体限定。上述源切片媒体文件的分配方法仅为一种可选示例，本实施例对此不做具体限定。
通过本申请实施例，通过从预处理设备集群中确定出与源切片媒体文件对应的预处理设备，从而保证了每一个源切片媒体文件都会有一个预处理设备对其进行处理，且由于预处理设备有多个，从而提高了对源切片媒体文件的处理效率。
作为一种可选的实施方案，转码设备根据画面区域处理结果对源切片媒体文件进行处理，得到处理后的目标切片媒体文件包括：
S1，转码设备根据画面区域处理结果获取源切片媒体文件所包含的帧画面中的关键区域；
S2，转码设备对关键区域执行第一操作，对源切片媒体文件所包含的帧画面中除关键区域之外的其他区域执行第二操作，其中，第一操作与第二操作为不同操作。
可选地，上述操作可以为改变源切片媒体文件中的关键区域的码率，或者为对关键区域进行渲染等。例如，第一操作为使用第一参数对上述关键区域的图像进行渲染；第二操作为使用第二参数对上述关键区域的图像进行渲染。其中，第一参数与第二参数不同。
可选地，上述第一参数与第二参数可以包括图像的颜色、饱和度等参数。
可选地，源切片媒体文件中的每一帧可以包含相同或不同的关键区域。
具体结合图6进行说明。如图6所示，在一个源切片媒体文件的一帧中，将显示有人、汽车等位置确定为关键区域，以及将显示字幕的区域确定为关键区域，用虚线圈起。将除虚线圈起的区域确定为其他区域，用阴影表示。从而可以对关键区域执行第一操作，对其他区域执行第二操作。
需要说明的是，对于确定关键区域的方法，本实施例不做具体限定。例如可以为：通过源切片媒体文件中的图像的颜色、形状、特定图像等来确定关键区域。
通过本实施例，通过转码设备根据画面区域处理结果获取源切片媒体文件所包含的帧画面中的关键区域，并对关键区域执行第一操作，对其他区域执行第二操作，从而实现了对源切片媒体文件中的不同区域执行不同操作的目的，提高了对源切片媒体文件进行处理的灵活性。
作为一种可选的实施方案，转码设备对关键区域执行第一操作，对源切片媒体文件所包含的帧画面中除关键区域之外的其他区域执行第二操作包括：
S1，转码设备对关键区域按照第一码率执行编码处理操作；
S2，转码设备对帧画面中除关键区域之外的其他区域按照第二码率执行编码处理操作；
其中，第一码率高于第二码率。
可选地，上述第一码率可以为超清码率，上述第二码率可以为高清码率。例如，继续结合图6进行说明。图6中已经确定出了关键区域与非关键区域。此时，将关键区域中的码率调整为超清码率，将其他区中的码率调整为高清码率，从而使关键区域中的人物、汽车与字幕更加清楚，同时由于其他区域为非超清码率，从而减小了源切片媒体文件的体积。
通过本实施例，通过转码设备对关键区域按照第一码率执行编码处理操作；对帧画面中除关键区域之外的其他区域按照第二码率执行编码处理操作，从而实现了对源切片媒体文件中的不同区域执行不同操作，以使不同区域的显示码率不同的目的，提高了对源切片媒体文件进行处理的灵活性。
作为一种可选的实施方案，在根据画面区域处理结果对源切片媒体文件进行处理，得到处理后的目标切片媒体文件之后，还包括：
S1，转码设备将与源多媒体文件中所包含的各个源切片媒体文件分别对应的目标切片媒体文件进行合并，得到与源多媒体文件对应的目标多媒体文件；
S2，转码设备将目标多媒体文件发送至播放客户端进行播放。
可选地，上述对目标切片媒体文件进行合并可以为根据各个目标切片媒体文件的起始时刻，确定目标切片媒体文件的顺序，根据目标切片媒体文件的顺序，将多个目标切片媒体文件合并成一个完整的目标多媒体文件，并将目标多媒体文件发送给播放客户端进行播放。
例如，有三个目标切片媒体文件，编号为1、2、3。三个目标切片媒体文件的起始时刻分别是0分0秒、4分0秒、2分0秒，因此，三个目标切片媒体文件的正确顺序应该为1、3、2。根据上述顺序，将三个目标切片媒体文件合并成一个目标多媒体文件，并将目标多媒体文件发送给播放客户端进行播放。
通过本实施例，通过转码设备将与源多媒体文件中所包含的各个源切 片媒体文件分别对应的目标切片媒体文件进行合并，得到与源多媒体文件对应的目标多媒体文件，并将目标多媒体文件发送至播放客户端进行播放，从而保证了在对源切片媒体文件进行处理的过程之后，可以得到完整的目标多媒体文件，提高了源切片媒体文件的处理准确度。
以下结合图7，对上述多媒体文件处理方法做整体说明。如图7所示，在相关技术中，不包含由虚线框所围住的部分。当获取到源多媒体文件时，根据源多媒体文件获取源切片媒体文件1到源切片媒体文件n，其中n为大于1的自然数。之后将源切片媒体文件1-n发送给转码设备1-n，由转码设备1-n对源切片媒体文件1-n进行转码，得到转码后媒体文件1-n，并将转码后媒体文件1-n合并为转码后多媒体文件。然而，使用该方法，仅仅做到了对源多媒体文件的转码。而本申请中，在获取到源切片媒体文件1-n后，通过虚线框中的步骤，将获取到的源切片媒体文件1-n发送到预处理设备1到预处理设备m中。其中，m为大于1的自然数。预处理设备1-m接收为每一个源切片媒体文件分配的切片预处理任务1到切片预处理任务n，并根据接收到的切片预处理任务1-n分析源切片媒体文件1-n，获得每一个源切片媒体文件的画面区域处理结果。当获取到每一个源切片媒体文件的画面区域处理结果后，将画面区域处理结果1-n发送到转码设备1-n。转码设备1-n根据画面区域处理结果1-n对源切片媒体文件1-n进行转码，得到目标切片媒体文件1-n，并将目标切片媒体文件进行合并，得到目标多媒体文件。
需要说明的是，上述转码设备可以不为n个，当上述转码设备不为n个时，有以下两种情况：
当源切片媒体文件数量小于等于转码设备数量时，直接通过转码设备对元切片媒体文件进行处理；当源切片媒体文件数量大于转码设备数量时，则多余的源切片媒体文件排队等待处理。
通过上述步骤，由于每一个源切片文件都获得了一个画面区域处理结果，从而可以根据画面区域处理结果对源多媒体文件中的每一个源切片媒 体文件进行处理，得到目标切片媒体文件，实现了对源多媒体文件中的每一个切片媒体文件进行智能化分析并处理的目的。从而解决了相关技术中仅仅能够对整个源多媒体文件进行智能化分析的问题，提高了对源多媒体文件进行处理的处理效率。

通过本申请实施例，通过预处理设备识别源切片媒体文件中的关键区域并保存，得到画面区域处理结果，从而实现了对源切片媒体文件中的不同区域执行不同操作的目的，提高了对源切片媒体文件进行处理的灵活性。
