本申请基于申请号为201610967202.2、申请日为2016年10月28日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
本发明涉及信息处理领域，尤其涉及一种数据切换方法、装置、终端及计算机可读存储介质。
为了满足用户的需求，同一视频文件可能有多种语言类型，例如，中文、英文等；当使用媒体播放器播放这种媒体文件时，用户选择不同语言类型进行播放时，将会涉及到音频数据或者字幕的切换。
在相关技术中，一般根据音频切换指令，查找需要切换的音轨的音频数据帧和同步戳，即根据进行音轨切换时视频的时间戳去查找对应的音频数据帧和同步戳。也就是说，当用户需要同步音频或者字幕时，如果视频不间断播放，根据同步戳查找需要切换的音轨的音频数据的方法，可能导致视频和音频、视频和字幕之间的同步耗时过长或者同步失败。
可见，采用相关技术进行视频相关数据切换时，可能导致视频和音频、字幕之间的同步耗时过长或者同步失败的问题，用户体验较差。

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。
实施例一：
本发明实施例提供一种数据切换方法，该数据切换方法的执行主体为数据切换装置，该数据切换装置可以内置或者外接于一终端，在实际应用中，上述终端可以为智能手机、电脑、机顶盒等具有媒体文件播放功能的终端，本发明实施例不做具体限定。
图1-1为本发明实施例一中的数据切换方法的流程示意图，参见图1-1所示，该方法包括：
S101：接收视频相关数据切换指令；
这里，视频相关切换指令用于将当前的视频相关数据切换为目标视频相关子数据，目标视频相关子数据为具有第一属性的视频相关子数据。
这里，视频相关数据包括音频数据和字幕数据。
在实际应用中，将预设的视频相关数据队列的视频相关子数据与预设的视频数据队列的视频帧同步出队并发送到各自的解码器进行解码播放的过程中，接收由用户触发或者系统预设(例如，设置第3秒为中文播放)的视频相关数据切换指令，本发明实施例不做具体限定。以切换音频数据为例进行具体说明：假设用户正在观看中文发音的影片时，如果用户想将该影片切换为英语发音并继续观看，则可以通过点击终端上用于切换音频属性的按钮或者选项进行视频相关数据的切换。
这里，属性用于表征视频相关数据的语言，例如，中文、英文等；或者，也可以是系统设置的。
S102：执行视频相关数据切换指令，从预设的视频相关数据队列的队首获取第i个视频相关子数据；
这里，i为大于或等于1的整数。这里，视频相关数据队列可以为按照视频帧的时间戳和预设次序，将具有不同属性的视频相关子数据依次排列
的队列。
在实际应用中，获取预设的视频相关数据队列中视频相关子数据也就是将视频相关子数据按照先入先出的次序出队，当执行视频相关数据切换指令，判断预设的视频相关数据队列是否非空，当预设的视频相关数据队列非空时，从预设的视频相关数据队列队首指针指向的地址获取用于出队的第i个视频相关子数据；当预设的视频相关数据队列为空时，等待与视频帧对应的视频相关子数据的入队。例如，假设预设的视频相关数据队列中存在视频相关子数据a，b，c，d，e。队首指针指向视频相关子数据a，队尾指针指向视频相关子数据e或者d，则执行视频相关数据切换指令，从预设的视频相关数据队列中获取队首指针指向的用于出队的视频相关子数据a，然后从预设的视频相关数据队列中删除a，并将队首指针加1；则当前预设的视频相关数据队列中存在视频相关子数据b，c，d，e。队首指针指向视频相关子数据b，队尾指针指向视频相关子数据e或者d。
S103：判断第i个视频相关子数据是否为具有第一属性的视频相关子数据，其中，如果第i个视频相关子数据不是具有第一属性的视频相关子数据，执行S102，其中，此时i＝i+1，依次类推，直至获得具有第一属性的视频相关子数据，并将具有第一属性的视频相关子数据确定为目标视频相关子数据；如果第i个视频相关子数据为具有第一属性的视频相关子数据，则执行S104；
在实际应用中，获取第i个视频相关子数据的属性，判断第i个视频相关子数据的属性与第一属性是否一致；其中，如果第i个视频相关子数据的属性与第一属性一致，则将第i个视频相关子数据确定为目标视频相关子数据；如果第i个视频相关子数据的属性与第一属性不一致，则第i个视频相关子数据不是具有第一属性的视频相关子数据，则释放不是具有第一属性的视频相关子数据。例如，获取第i个视频相关子数据a的属性为中文，判断视频相关子数据a的属性是否与第一属性一致，当第一属性为英语时，则释放该视频相关子数据a；当第一属性为中文时，则将该视频相关子数据a确定为目标视频相关子数据。
S104：发送到解码器进行解码，以实现与对应的视频帧同步播放。
在实际应用中，播放器同时调用音频解码器对上述获取的目标音频子数据进行解码，调用字幕解码器对目标字幕子数据进行解码，并依据同样的时间戳将解码后音频子数据、字幕子数据和视频帧输出到播放窗口并使之保持同步。
在实际应用中，假设视频相关数据队列为如图1-2所示的队列，假设该视频相关队列的属性种类为两种，也就是说，视频相关数据队列中视频相关子数据a1和a2为与第二视频帧对应的不同属性的视频相关子数据，a3、a4为与第三视频帧对应的具有不同属性的视频相关子数据，a1、a3具有相同的属性。当播放第二视频帧后，接收到视频相关数据切换指令，则从视频相关数据队列的队首取与第三视频帧对应的视频相关子数据a3，判断a3的属性，如果a3的属性为第一属性，则将a3发送到解码器进行解码；如果a3的属性不是第一属性，则将队首指针加1，从视频相关数据队列中取视频相关子数据a4，如果视频相关子数据a4的属性为第一属性，则将视频相关子数据a4确定为目标视频先关子数据，将该目标视频相关子数据发送到解码器进行解码。由于该视频相关队列中视频相关数据的属性为两种，因此，从视频相关数据队列中判断与视频帧对应的视频相关子数据的次数有限，能够实现视频相关数据的平滑切换。
本实施例提供的数据切换方法，首先，通过接收视频相关数据切换指令，执行视频相关指令，从预设的视频相关数据队列的队首获取第i个视频相关子数据，如果第i个视频相关子数据不是具有第一属性的视频相关子数据，则从预设的视频相关数据队列中获取第i+1个视频相关子数据，依次类推，直至获得具有第一属性的视频相关子数据，并将具有第一属性的视频相关子数据确定为目标视频相关子数据。也就是说，视频相关子数据的属性信息为有限个，按照与视频帧对应的视频相关子数据的属性信息，从视频相关数据队列的队首获取目标视频相关子数据，提高了切换速度，能够实现视频相关子数据的平滑切换，然后，将目标视频相关子数据发送到解码器进行解码，以实现与对应的视频帧同步播放，缩短了视频相关数据和视频同步时间，提高了用户体验。
基于前述实施例，本实施例提供了一种数据切换方法，如图2所示，该方法包括：
S201：接收媒体文件播放请求；
这里，播放请求用于播放当前媒体文件。
在实际应用中，媒体文件为编码后的视频数据和编码后视频相关数据合成的文件。
S202：响应媒体文件播放请求，获取媒体文件；
S203：将媒体文件进行分离，获得视频数据和视频相关数据；
在实际应用中，可以采用多媒体视频处理工具，例如，快进动态图像专家组(FFMPEG，Fast Forward Moving Picture Experts Group)软件将媒体文件进行分离，当然，也可以为其它软件，本发明实施不做具体限定。
S204：对视频数据进行处理，获得至少一个视频帧；
S205：按照预设分割策略，将视频相关数据进行分割，获得与至少一个视频帧对应的视频相关子数据；
S206：按照至少一个视频帧的时间戳和预设的次序，将与视频帧对应的具有不同属性的视频相关子数据依次排列，获得视频相关数据队列。
这里，预设的次序为视频相关子数据的属性的排列次序，属性表示视频相关子数据的语言类型，例如：中文、英文等，本发明实施例不做具体限定。
在实际应用中，预先创建一个队列，按照至少一个视频帧的时间戳和预设的具有不同属性的视频相关子数据的排列次序，将视频相关子数据按照先入先出的次序存储在预设的队列中。例如，预先创建一个队列，假设预设的具有不同属性的视频相关子数据的排列次序为偶数位为中文，奇数位为英语，则将与第一视频帧对应的具有英语属性的视频相关子数据第一个入队，然后将与第一视频帧对应的具有中文属性的视频相关子数据第二个入队，依次类推，则获得视频相关数据队列。
在实际应用中，预先创建的队列可以为链式队列，也可以为循环队列，本发明实施例不做具体限定。该队列的队首指针和队尾指针可以自定义设
置，为了避免在判断获得的视频相关数据队列的队满和队空时出现误判，在设置队首指针和队尾指针的指向地址时，需要将其中之一指向空位，例如，队首指针可以指向实际队首，队尾指针指向队尾的下一个空位；也可以将队首指针指向队首前一个空位，队尾指针指向实际队尾。
实施例三：
基于前述实施例，本实施例提供了一种数据切换方法，如图3所示，该方法包括：
S301：接收媒体文件播放请求；
这里，播放请求用于播放当前媒体文件。
这里，媒体文件可以是视频媒体文件，也可以是音频媒体文件，本发明实施例不做具体限定。
S302：响应媒体文件播放请求，获取媒体文件；
S303：将媒体文件进行分离，获得视频数据和视频相关数据；
这里，分离可以为将包含音频、视频、字幕的媒体文件分成独立的音频数据、视频数据和字幕数据。
在实际应用中，可以采用媒体文件分离器将封装合成的媒体文件进行分离，得到独立的视频数据和视频相关数据。例如，播放器打开媒体文件，播放器调用分离器将媒体文件分离为单独的视频数据和视频相关数据。
S304：对视频数据进行处理，获得至少一个视频帧；
S305：按照预设分割策略，将视频相关数据进行分割，获得与至少一个视频帧对应的视频相关子数据；
S306：获取数据类型不能被读取的视频相关子数据；
S307：从视频相关子数据中释放数据类型不能被读取的视频相关子数据；
S308：按照至少一个视频帧的时间戳和预设的次序，将与视频帧对应的具有不同属性的视频相关子数据依次排列，获得视频相关数据队列。
实施例四：
基于前述实施例，本实施例提供了一种数据切换方法，如图4所示，该方法包括：
S401：接收媒体文件播放请求；
这里，播放请求用于播放当前媒体文件。
S402：响应媒体文件播放请求，获取媒体文件；
S403：判断视频相关数据队列是否队满；其中，如果视频相关数据队列队满，则执行S410；如果视频相关数据队列未满，则执行S404；
S404：将媒体文件进行分离，获得视频数据和视频相关数据；
S405：对视频数据进行处理，获得至少一个视频帧；
S406：按照预设分割策略，将视频相关数据进行分割，获得与至少一个视频帧对应的视频相关子数据；
S407：获取数据类型不能被读取的视频相关子数据；
这里，数据类型包括：视频、音频、字幕。
S408：从视频相关子数据中释放数据类型不能被读取的视频相关子数据；
S409：按照至少一个视频帧的时间戳和预设的次序，将与视频帧对应的具有不同属性的视频相关子数据依次排列，获得视频相关数据队列。
S410：如果视频相关数据队列队满，则停止将媒体文件进行分离。
本实施例提供的数据切换方法，通过在将媒体文件进行分离前，判断视频相关数据队列是否队满，如果视频相关数据队列队满，则停止将媒体文件进行分离，避免了视频相关数据队列队满时，后写入的视频相关子数据的覆盖先写入的视频相关子数据的风险，能够保证视频相关数据的完整性。
实施例五：

在本发明其它实施例中，装置还可以包括：存储模块，配置为接收媒体文件播放请求，其中，播放请求用于播放当前媒体文件；响应媒体文件播放请求，获取媒体文件；将媒体文件进行分离，获得视频数据和视频相关数据；对视频数据进行处理，获得至少一个视频帧；按照预设分割策略，将视频相关数据进行分割，获得与至少一个视频帧对应的视频相关子数据；按照至少一个视频帧的时间戳和预设的次序，将与视频帧对应的具有不同属性的视频相关子数据依次排列，获得视频相关数据队列。
在本发明其它实施例中，装置还可以包括：删除模块，配置为获取数据类型不能被读取的视频相关子数据；从视频相关子数据中释放数据类型不能被读取的视频相关子数据。
在本发明其它实施例中，装置还可以包括：判断模块，配置为判断视频相关数据队列是否队满；如果视频相关数据队列队满，则停止将媒体文件进行分离；如果视频相关数据队列未满，则将媒体文件进行分离。
