附图说明
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7为本公开实施例提供的电子设备的硬件结构示意图。
具体实施方式
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。
目前，通过终端上的播放器可以进行媒体数据播放，例如视频播放、音频播放等，在一些应用场景中，一些播放器通常需要一边下载一边播放。而在播放过程中，如图1a所示，终端100的界面中显示播放器110，播放器110可具有进度条111和进度条滑块112，用户可以通过拖拽进度条滑块112来控制播放进度，用户可将进度条滑块112拖拽到目标播放进度处，进而使得播放器110从目标播放进度处继续播放。其中终端100不限于手机、平板电脑、笔记本电脑、个人电脑、个人数字助理、可穿戴设备等。
而在用户将进度条拖拽到目标播放进度处后，通常需要等待一段时间后播放器才能响应用户拖拽操作，其原因是，如图1b所示，现有技术中，播放器通常在一个单独的读线程(Read  Thread)中进行解复用操作和下载操作，解复用操作是将下载的媒体文件中多个轨道分解出来，得到图像轨道、音频轨道、字幕轨道等的数据，并进行缓存，而播放器通常在读线程完成当前完整的一帧(指当前被解复用的帧)的解复用操作后，才能检测是否存在用户的拖拽操作指令；若存在用户的拖拽操作指令则响应用户的拖拽操作指令，也即从拖拽操作指令对应的播放进度处继续播放，若不存在用户的拖拽操作则读线程继续下一帧的解复用操作；而其中在读线程完成当前一帧的解复用操作过程中需要从套接字Socket数据包持续读取已下载数据直至读取到可以用于解码完整帧的数据长度为止，并对读取的已下载数据解复用，其中已下载数据可以为视频数据、音频数据等媒体数据。
因此在消息线程(Msg Thread)接收到用户拖拽操作指令后，需要等待读线程完成当前一帧的解复用操作后，用户拖拽操作指令才能被响应，导致拖拽操作的响应产生一定的时延，响应速度较慢，导致播放器不能马上从目标播放进度处继续播放，用户等待时间较长，影响观看体验。
为了解决上述技术问题，在本公开实施例中，接收用户对播放器的播放进度的控制指令(例如拖拽操作指令)，其中控制指令包括待播放的目标播放进度，然后根据所述控制指令，中断播放器对已下载数据的解复用操作；控制播放器响应控制指令，以从目标播放进度继续播放，由于能够及时控制解复用操作中断，因此才能快速响应控制指令，使得播放器更快的从目标播放进度处继续播放，缩短用户等待时间，提高用户观看体验。
参考图2，图2为本公开实施例提供的播放控制方法流程示意图一。本实施例的方法可以应用在终端设备中，该播放控制方法包括：
S201、接收用户对播放器的播放进度的控制指令，所述控制指令包括待播放的目标播放进度。
在本实施例中，用户可以对终端设备的播放器的播放进度进行控制，将播放进度调节至待播放的目标播放进度，在一种可选实施例中，用户可以拖动播放器进度条的滑块，将进度条的滑块拖动至待播放的目标播放进度，进而终端设备可以接收用户对播放器的播放进度的控制指令，控制指令包括待播放的目标播放进度。当然，用户对播放器的播放进度的控制指令并不限于上述举例中的拖动播放器进度条的滑块，其他方式的控制指令亦可。
S202、根据所述控制指令，中断所述播放器对已下载数据的解复用操作。
在本实施例中，考虑到现有技术中播放器通常在读线程完成当前一帧的解复用操作后，才能去响应控制指令，为了使控制指令能够及时被响应，因此在接收到控制指令后，及时中断解复用操作，而不需要读线程完成当前一帧的解复用操作后才去响应控制指令，极大的提高了播放器对控制指令的响应速度。
可选的，由于现有技术中读线程需要从套接字Socket数据包持续读取已下载数据直至读取到可以用于解码完整帧的数据长度为止，并对读取的已下载数据解复用，才会去响应控制指令，除非无法从套接字Socket数据包去读到已下载数据，否则不会中断，因此，本实施例中在根据所述控制指令，中断所述播放器对已下载数据的解复用操作时，根据所述控制指令，中断将套接字Socket数据包中的所述已下载数据发送给所述播放器的读线程，以使所述读线程在无法获取到所述已下载数据后，中断对所述已下载数据的解复用操作。本实施例中由于读线程无法继续从套接字Socket数据包获取到已下载数据，出现读数据错误，因此无法继续进行解复用操作，也即实现及时中断播放器对已下载数据的解复用操作，且该上述技术方案 对播放器程序代码改动较小，不需要改动读线程的程序代码。
需要说明的是，由于读线程在对当前一帧进行解复用操作过程中无法继续获取到已下载数据，也即无法得到可以用于解码完整帧的数据长度，因此解复用操作得到的也不是完整帧，也即解复用操作产生不完整数据，无法进行后续的解码得到完整的一帧视频帧、音频帧，因此可以在中断将套接字Socket数据包中的所述已下载数据发送给所述播放器的读线程之后，丢弃所述读线程在中断解复用操作时产生的不完整数据，避免影响后续解码过程。
S203、控制所述播放器响应所述控制指令，以从所述目标播放进度继续播放。
在本实施例中，在中断所述播放器对已下载数据的解复用操作后，即可及时控制播放器响应控制指令，也即播放器可以从目标播放进度开始继续播放，提高了对控制指令的响应速度，缩短用户在发出对播放器的播放进度的控制指令后的等待时间，提高用户观看体验。
在本实施例提供的播放控制方法中，接收用户对播放器的播放进度的控制指令，所述控制指令包括待播放的目标播放进度；根据所述控制指令，中断播放器对已下载数据的解复用操作；控制播放器响应所述控制指令，以从目标播放进度继续播放。本实施例通过控制播放器及时中断解复用操作，从而及时响应用户对播放器的播放进度的控制指令，使得播放器更快的根据控制指令从目标播放进度处继续播放，缩短用户等待时间，提高用户观看体验。
在上述实施例的基础上，在S203中控制所述播放器响应所述控制指令，以从所述目标播放进度继续播放时，可能存在两种情况，其中一种是目标播放进度对应时刻处未预先完成缓存，也即目标播放进度处未下载数据或未完成解复用操作，另一种情况是目标播放进度处已预先完成缓存，也即目标播放进度处已预先完成解复用操作，下面将针对上述两种情况分别进行说明。
可选的，在第一种情况中，如图3所示，S203所述控制所述播放器响应所述控制指令，以从所述目标播放进度继续播放，具体可包括：
S301、若所述目标播放进度对应时刻处未预先完成缓存，则从所述目标播放进度对应时刻处将Socket数据包中的所述已下载数据发送给所述读线程；
S302、控制所述读线程从所述目标播放进度对应时刻处的已下载数据继续进行解复用操作；
S303、对解复用操作结果进行解码，基于解码结果从所述目标播放进度继续播放。
在本实施例中，在从目标播放进度继续播放时，若目标播放进度对应时刻处未预先完成缓存，则可从目标播放进度处开始进行缓存，也即从目标播放进度处开始将Socket数据包中已下载数据发送给读线程，读线程基于获取到的已下载数据进行解复用操作，得到复用操作结果，可包括图像轨道、音频轨道、字幕轨道等数据，继而可基于图像轨道、音频轨道、字幕轨道等数据进行解码，得到对应的图像、音频、字幕等解码结果，播放器可基于解码结果进行播放，实现从目标播放进度继续播放。
可选的，在第二种情况中，S203所述控制所述播放器响应所述控制指令，以从所述目标播放进度继续播放，具体可包括：
若所述目标播放进度对应时刻处已预先完成缓存，则直接对缓存数据进行解码，基于解码结果从所述目标播放进度继续播放。
在本实施例中，在从目标播放进度继续播放时，若目标播放进度处已预先完成缓存，目标播放进度处已完成解复用操作，并进行缓存，可对缓存的解复用结果进行解码，得到对应 的图像、音频、字幕等解码结果，播放器可基于解码结果进行播放，实现从目标播放进度继续播放。当然，若目标播放进度处预先完成了解码，播放器可直接基于解码结果继续从目标播放进度处进行播放。
进一步的，对于目标播放进度对应时刻处已预先完成缓存的情况，说明解复用操作已进行到目标播放进度之后，例如目标播放进度处为第100秒，解复用操作已进行到第120秒，因此在中断解复用操作，响应控制指令，从目标播放进度继续播放后，还需要继续从解复用操作中断处执行解复用操作，如图4所示，具体过程可包括：
S401、从解复用操作中断处将Socket数据包中的所述已下载数据发送给所述读线程；
S402、控制所述读线程从所述解复用操作中断处的已下载数据继续进行解复用操作，并将解复用操作结果进行缓存。
在本实施例中，可从解复用操作中断处开始将Socket数据包中已下载数据发送给读线程，读线程基于获取到的已下载数据继续进行解复用操作，得到复用操作结果，并将解复用操作结果进行缓存，保证了播放器能够继续缓存。
在上述实施例的基础上，S401所述从解复用操作中断处将Socket数据包中的所述已下载数据发送给所述读线程，包括：
将Socket数据包中与解复用操作丢弃的不完整数据对应的已下载数据重新发送给所述读线程，并继续将该已下载数据后续的已下载数据发送给所述读线程。
在本实施例中，由于在中断将套接字Socket数据包中的已下载数据发送给所述播放器的读线程之后，丢弃了读线程在中断解复用操作时产生的不完整数据，因此，为了保证解复用操作结果的连续性，可对丢弃部分重新进行解复用操作，也即将Socket数据包中与解复用操作丢弃的不完整数据对应的已下载数据重新发送给读线程，并继续将该已下载数据后续的已下载数据发送给读线程，使得读线程根据获取到的已下载数据继续进行解复用操作，实现了从丢弃位置重新进行解复用操作。
在上述任一实施例的基础上，如图5所示，本发明实施例提供一种播放控制方法，该播放控制方法包括：
S501、通过所述播放器的消息线程接收用户对播放器的播放进度的控制指令。
在本实施例中，播放器的消息线程是播放器内部的消息线程，让播放器行为不阻塞界面操作。本实施例中可通过播放器的消息线程接收用户通过界面操作对播放器的播放进度的控制指令。
S502、由所述消息线程根据所述控制指令生成中断指令；
S503、根据所述中断指令，中断将Socket数据包中的所述已下载数据发送给所述播放器的读线程。
在本实施例中，消息线程在接收到控制指令后，可根据控制指令向Socket数据包的处理装置发送中断指令，进而使得该处理装置根据中断指令中断将Socket数据包中的已下载数据发送给播放器的读线程。
S504、控制所述播放器响应所述控制指令，以从所述目标播放进度继续播放。
在本实施例中，控制播放器响应控制指令的过程可同上述实施例，此处不再赘述。
在上述各实施例提供的播放控制方法中，通过控制播放器及时中断解复用操作，从而及时响应用户对播放器的播放进度的控制指令，使得播放器更快的根据控制指令从目标播放进 度处继续播放，缩短用户等待时间，提高用户观看体验。

以上描述仅为本公开的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本公开中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本公开中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
此外，虽然采用特定次序描绘了各操作，但是这不应当理解为要求这些操作以所示出的特定次序或以顺序次序执行来执行。在一定环境下，多任务和并行处理可能是有利的。同样地，虽然在上面论述中包含了若干具体实现细节，但是这些不应当被解释为对本公开的范围的限制。在单独的实施例的上下文中描述的某些特征还可以组合地实现在单个实施例中。相反地，在单个实施例的上下文中描述的各种特征也可以单独地或以任何合适的子组合的方式实现在多个实施例中。
尽管已经采用特定于结构特征和/或方法逻辑动作的语言描述了本主题，但是应当理解所附权利要求书中所限定的主题未必局限于上面描述的特定特征或动作。相反，上面所描述的特定特征和动作仅仅是实现权利要求书的示例形式。
