图1为本申请实施例提供的一种移动终端的播放控制方法的流程示意图，该方法可以由移动终端的播放控制装置执行，其中该装置可由软件和/或硬件实现，一般可集成在移动终端中。如图1所示，该方法包括：
步骤101、在播放目标视频片段前从服务端获取所述目标视频片段对应的用户评价信息。
示例性的，本申请实施例中的移动终端具体可为手机、智能手表、平板电脑、游戏机、个人数字助理和数字多媒体播放器等包含显示屏的设备。
目前，视频播放应用所提供的视频资源越来越丰富，且支持点播以及直播等功能，所以选择视频播放应用来观看视频的用户越来越多。移动终端上可装载的视频播放应用有很多，如爱奇艺视频、优酷视频、腾讯视频以及搜狐视频等等，这些视频播放应用为用户提供了大量的免费视频资源，用户可选择在线播放或者离线播放等播放模式，本申请实施例尤其适用于在线播放模式的应用场景。
示例性的，在执行本步骤之前，可将即将播放的目标视频资源（如用户选择播放的一部电影、一集电视剧或一期电视节目等）以预设时间间隔划分为多个视频片段。其中，预设时间间隔可为固定值（如5分钟），也可为目标视频资源总播放时长的预设比例值（如1/30），具体数值不做限定。根据所述目标视频资源的播放进度确定目标视频片段，目标视频片段可理解为当前正在播放的视频片段的下一个视频片段。
当用户选择在线观看模式时，在观看视频的过程中会对视频内容进行评价，如发布弹幕、点赞、评论以及在讨论区与其他在线用户聊天等等，这些用户表达自己对视频内容评价的信息均可作为用户评价信息。示例性的，所述用户评价信息包括所述目标视频片段在历史播放过程中接收到的弹幕数量、弹幕内容、点赞次数以及讨论区聊天记录中的至少一项。
用户评价信息一般可以与视频的播放时间（与视频的播放时间轴相对应）存在一定的对应关系，也就是说用户在看到自己想要评价的视频内容时会在对应的播放时刻发表评价信息，因此，可根据用户评价信息的发布时的播放进度确定其对应的视频片段，并将此对应关系上传至服务端（例如可以是正在使用的视频播放应用程序对应的服务器），以便服务端汇总当前的视频片段所对应的所有曾观看过该视频片段的用户所发布的评价信息，也就是说目标视频片段对应的用户评价信息包括服务端汇总的目标视频片段所对应的所有曾观看过目标视频片段的用户所发布的评价信息。
本步骤中，可在即将播放目标视频片段之前从服务端获取其对应的用户评价信息，也可在用户选择播放目标视频资源时开始获取该目标视频资源中包含的所有视频片段分别对应的用户评价信息，本申请实施例不做限定。
步骤102、根据所述用户评价信息确定目标视频片段是否满足预设降功耗条件。
示例性的，用户评价信息可以反映出曾经观看过目标视频片段的用户对目标视频片段的喜好程度或关注程度等。例如，当用户评价信息包含弹幕数量时，若弹幕数量较多，则说明用户关注程度较高；又如，当用户评价信息包含点赞次数时，若点赞次数较多，则说明很多用户喜欢该视频片段；再如，当用户评价信息包含弹幕内容或讨论区聊天记录时，可对弹幕内容和聊天记录中的文字进行识别，从中提取出能够反映用户评价的字段，如“好看”、“精彩”、“无聊”、“想快进”等等，根据识别出的字段来确定用户的观看态度。
本申请实施例中，预设降功耗条件可用于衡量用户对视频片段的满意程度，包括受关注度或是否喜欢观看等，当根据用户评价信息确定目标视频片段受关注程度较低或很多用户不喜欢观看时，可确定目标视频片段满足预设降功耗条件。
步骤103、若满足所述预设降功耗条件，则在播放所述目标视频片段时进行降功耗处理。
示例性的，所述降功耗处理可包括：降低屏幕亮度、降低屏幕刷新率、降低图层绘制帧率、降低图层合成帧率、降低显示画面分辨率和减小播放音量中的至少一项。
在一些实施例中，本步骤可包括：根据所述用户评价信息确定所述目标视频片段对应的目标降功耗策略；在播放所述目标视频片段时采用所述目标降功耗策略进行降功耗处理。其中，降功耗策略中可包括降功耗处理的方式以及对应的参数值。这样设置的好处在于，能够更加细致地根据用户评价信息进行不同程度的降功耗处理，更好地兼顾用户的观看需求和节省功耗的效果。
示例性的，所述目标降功耗策略包括降低屏幕亮度、降低屏幕刷新率、降低图层绘制帧率、降低图层合成帧率、降低显示画面分辨率和减小播放音量中的至少一项以及对应的参数值。其中，降低屏幕亮度对应的参数值为目标屏幕亮度值，降低屏幕刷新率对应的参数值为目标屏幕刷新率，降低图层绘制帧率对应的参数值为目标图层绘制帧率，降低图层合成帧率对应的参数值为目标图层合成帧率，降低显示画面分辨率为目标显示画面分辨率，减小播放音量对应的参数值为目标音量值。可以理解的是，为了增强降功耗的效果，可以同时采用上述多种降功耗的方式，例如同时降低屏幕亮度、降低屏幕刷新率、降低图层绘制帧率、降低图层合成帧率、降低显示画面分辨率和减小播放音量。不同的降功耗策略之间的区别可体现在降功耗方式的不同、降功耗方式的数量不同以及降功耗方式对应的参数值不同等各个方面，本申请实施例不做限定。
本申请实施例对移动终端中装载的操作系统不做限定，可以是安卓（Android）系统、手机窗口（Windows Phone，WP）操作系统、Linux及IOS系统等等。示例性的，为了便于说明，本申请实施例以常见的Android系统进行后续的说明。
为了便于理解，下面以Android系统为例，对Android系统中显示画面从生成到显示的过程进行简单的说明。图2为本申请实施例提供的一种显示过程示意图。
首先，在应用（Application）层，每个应用程序（以下简称应用或APP）包含1个或多个图层，各个应用APP1、APP2…APPN按照自己的应用设计情况（一般由对应的安装包APK决定）各自单独执行图层绘制（Render）操作（即绘制图层上的图像），并在绘制操作处理完成后，各应用将所绘制的所有图层发送给执行图层合成操作的图层合成模块（Surface flinger）。
然后，在应用框架（Framework）层，所有图层（包括可见图层和不可见图层）组成一个图层列表，定义为ListAll。图层合成模块从ListAll中挑选出可见图层组成可见图层列表，定义为DisplayList。随后，图层合成模块从系统中三个可循环使用的帧缓冲器（Frame Buffer，简称BF或buffer）中，找出一个空闲的FB，并在该空闲的FB上，根据应用配置信息，例如哪个图层应该置底、哪个图层应该置顶、哪个区域为可见区以及哪个区域为透明区等等，通过合成（Compose）操作，将DisplayList中包含的图层叠加在一起，得到最终的待显示画面。
最后，在内核（Kernel）层，可以将待显示画面传输给显示硬件（包括显示控制器和显示屏，使待显示画面最终显示在显示屏上。这里对显示屏的类型不做限定，例如可以是液晶显示器（Liquid Crystal Display, LCD）。
另外，Android系统在显示刷新的过程中引入了同步（Vsync）刷新机制。图3为本申请实施例提供的Vsync显示刷新机制的示意图。具体地，Vsync刷新机制其实就是在整个显示流程中，插入“心跳”即系统同步（Vsync）信号，由显示控制器发送给CPU，用于产生Vsync中断，以控制每次图层绘制操作和图层合成操作都需要按照心跳来完成，从而将整个显示过程中的关键步骤都纳入到Vsync的统一管理机制。Vsync信号的频率目前常见为60Hz。如图3所示，假设Vsync信号周期为T，不考虑信号的传输延迟，第一个Vsync信号Vsync1到达CPU后，CPU向各应用转发该第一个Vsync信号Vsync1，各应用响应用户在显示屏上的触摸滑动等操作，开始执行绘制操作；在各应用完成绘制操作后，得到各应用所绘制的多个图层。第二个Vsync信号Vsync2到达CPU后，CPU向图层合成模块转发该第二个Vsync信号Vsync2，图层合成模块开始执行图层合成操作，将各应用所绘制的多个图层进行合成，生成待显示画面。第三个Vsync信号Vsync3到达CPU后，系统开始执行显示刷新，并将该待显示画面最终显示在显示屏上。由上述描述可知，应用程序、图层合成模块和显示屏接收到的Vsync信号的频率是一致的，且是预先设置好的固定值。
在移动终端图层绘制、合成和刷新显示的流程中，存在3种帧率：绘制帧率、合成帧率和刷新率。
其中，绘制帧率为图层绘制完成后，触发图层合成模块进行图层合成的帧率，可以理解为单位时间（例如，1秒钟）绘制的图层帧数。所述绘制帧率包括应用程序对应的（图层）绘制帧率和单类图层对应的（图层）绘制帧率。系统中运行的应用程序可能有多个，每个应用程序可能包括多个图层，例如，视频播放器应用程序下一般包括三个图层：一个显示视频内容的图层，可定义为U1；两个SurfaceView类型的图层，一个用于显示弹幕内容，可定义为U2，另一个用于显示用户界面（User Interface，UI）控件（如播放进度条、音量控制条以及各种控制按钮等）和广告，可定义为U3。所述应用程序对应的绘制帧率为应用程序单位时间内执行绘制操作的次数，其中，执行一次绘制操作时可能绘制了一个或者多个图层。所述单类图层对应的绘制帧率为同一编号或名称（如前面的U1、U2或U3）的图层单位时间内被触发绘制的次数。
合成帧率为把各个应用程序绘制的图层合成为一个待显示画面的帧率，可以理解为单位时间合成的画面帧数。
刷新率为移动终端显示屏画面刷新的帧率。一般，显示屏会以60Hz的刷新率刷新。
在一些实施方式中，可通过将显示屏的亮度值调整到目标屏幕亮度值来降低屏幕亮度，包括将显示屏的亮度值调到最低（相当于熄灭屏幕）。
可通过将用于绘制图层、合成图层或屏幕刷新的参考信号（如Vsync信号）的频率调整为目标图层绘制帧率、目标图层合成帧率或目标屏幕刷新率来实现降低图层绘制帧率、降低图层合成帧率或降低屏幕刷新率，且绘制图层、合成图层和屏幕刷新对应的Vsync信号的频率可以相同（如均由60Hz降为50Hz）也可以各不相同（如由60Hz分别降为50Hz、52Hz和54Hz）。也可通过变更图层绘制操作、图层合成操作和屏幕刷新操作对参考信号的响应机制来实现将图层绘制帧率、图层合成帧率或屏幕刷新率降低至目标图层绘制帧率、目标图层合成帧率或目标屏幕刷新率。例如，接收到的第2n+1个信号响应，接收到的第2n个信号不响应；又如，以n个（如5个）信号为一组，每组中的第一类预设编号（如1,2,4,5）的信号响应，第二类预设编号（如4）的信号不响应。
示例性的，如上述举例，将当前的图层绘制帧率60Hz降至目标图层绘制帧率50Hz，可通过以下两种方式实现：第一种，将发送至应用程序的Vsync信号的频率更改为50Hz；第二种，假设Vsync信号的频率为60Hz，以6个信号为一组，控制应用程序响应每组中的5个第一类预设编号（如1,2,3,4和5）的信号来绘制图层，不响应1个第二类预设编号（如6）的信号。
降低显示画面分辨率可以在图层绘制阶段或图层合成阶段来实现，例如应用程序在绘制目标视频片段对应的图层时降低图像的分辨率至目标显示画面分辨率，又如图层合成模块可在进行合成前或在合成过程中将目标视频片段对应的显示画面分辨率降至目标显示画面分辨率。其中，调低分辨率可通过图像处理相关手段实现。
