具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
目前，移动终端在播放本地音频时，支持两种音频类型：普通音频及低时延视频。其中，普通音频对音效要求较高，因此，需要对普通音频进行混音和音效处理，由此可以将两个普通音频帧之间的时间间隔设置的稍长，例如，两个音频帧之间的时间间隔可以设置为20ms。而低时延音频对实时性要求较高，因此，无需对低时延音频进行混音和音效处理，由此可以将两个低时延音频帧之间的时间间隔设置的较短，例如，两个低时延音频帧之间的时间间隔可以设置为5ms。
当对一段音频数据在跨设备之间进行共享时，例如，移动终端将本地的音频发送到共享设备(例如，电视)上播放时，由于移动终端无法获取共享设备的音频播放能力，因此移动终端只能创建普通音频，并将普通音频发送到共享设备进行播放，由此导致音频共享时无法满足低时延音频的要求。
基于上述问题，本申请实施例提出了一种跨设备音频播放方法，能够实现无损的跨设备音频播放，提高用户的体验。
本申请实施例可以应用于移动终端；其中，移动终端也可以称为终端设备、用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。 移动终端可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、车联网终端、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(Set Top Box，STB)、用户驻地设备(Customer Premise Equipment，CPE)和/或用于在无线系统上进行通信的其它设备以及下一代通信系统，例如，5G网络中的移动终端或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的移动终端等。
本申请实施例对执行该技术方案的移动终端的具体形式不做特殊限制。
现结合图1-图3对本申请实施例提供的跨设备音频播放方法进行说明。
如图1所示，为本申请提供的跨设备音频播放方法的应用场景一个实施例的架构图。参考图1，移动终端100可以通过无线通讯方式(例如，蓝牙、WIFI等)与第一设备200进行通讯。其中，第一设备200可以是具有无线通讯功能及音频播放功能的设备，例如，智能音箱、手机、电视、平板等。本申请实施例对第一设备200的具体形式不作限定。
如图2所示，为本申请提供的跨设备音频播放方法一个实施例的流程示意图，可以包括：
步骤101，第一设备200获取音频能力信息，将音频能力信息发送给移动终端100。
具体地，音频能力信息用于标识第一设备200的音频能力，音频能力信息可以包括第一类型及第二类型。第一类型可以用于标识普通音频的能力，第二类型可以用于标识低时延音频的能力。
其中，第一设备200的音频能力信息可以在第一设备200中预先设置，例如，可以在第一设备200出厂时设置。第一设备200的音频能力信息也可以通过收集第一设备200中的硬件信息自动生成，例如，判断第一设备200中的音频硬件信息，以确定第一设备200是否支持第一类型和/或第二类型音频。
步骤102，第一设备200将音频能力信息发送给移动终端100。
当移动终端100与第一设备200建立连接(例如，蓝牙连接或WIFI连接等)后，第一设备200可以将音频能力信息发送给移动终端100，使得跨设备之间可以共享音频能力信息。
可选地，第一设备200还可以在收到移动终端100的查询请求后，发送音频能力信息给移动终端100。其中，查询请求可以用于查询第一设备200的音频能力信息。
步骤103，移动终端100接收第一设备200的音频能力信息。
具体地，当移动终端100接收第一设备200的音频能力信息后，解析音频能力信息，获取音频能力信息中的类型(例如，第一类型和/或第二类型)。
步骤104，检测到用户用于启动音频应用的第一操作，移动终端100基于音频能力信息创建音频数据流。
具体地，用户可以在移动终端100上进行操作，以启动音频应用，例如，用户可以在移动终端100中通过点击应用程序的图标打开游戏应用或通话应用等。响应于接 收到的用户启动音频应用的操作，移动终端100可以基于音频能力信息创建音频数据流。
示例性的，移动终端100可以判断音频能力信息中的类型。
若判断音频能力信息中包含第一类型，移动终端100建立基于第一类型的音频数据流，例如，移动终端100可以创建普通音频数据流。
若判断音频能力信息中包含第一类型和第二类型，移动终端100可以分别建立第一类型和/或第二类型的音频数据流。示例性的，移动终端100可以根据音频应用的类型创建普通音频数据流和/或低时延音频数据流，例如，若音频应用为游戏或通话等类型，则移动终端100可以建立低时延音频数据流。若音频应用为音乐等类型，则移动终端100可以建立普通音频数据流。
步骤105，移动终端100将音频数据流进行标记。
具体地，当移动终端100创建第一类型音频数据流和/或第二类型音频数据流之后，还可以对第一类型音频数据流和/或第二类型音频数据流进行标识，以在第一设备200处进行识别。在具体实现时，移动终端100可以将第一类型音频数据流标识为第一类型，移动终端100还可以将第二类型音频数据流标识为第二类型。
步骤106，移动终端100将音频数据流发送给第一设备200。
具体地，若移动终端100生成第一类型音频数据流，则可以将该第一类型音频数据流发送给第一设备200；若移动终端100生成第二类型音频数据流，则可以将该第二类型音频数据流发送给第一设备200；若移动终端100生成第一类型音频数据流和第二类型音频数据流，则可以将该第一类型音频数据流和第二类型音频数据流发送给第一设备200。
进一步地，移动终端100还可以获取当前网络环境的状态信息。其中，网络环境的状态信息可以包括时延及负载。在具体实现时，移动终端100可以基于网络传输协议，例如，传输控制协议(Transmission Control Protocol，TCP)，识别出当前网络环境的时延及负载信息。示例性的，TCP网络报文中支持往返时延(Round-Trip Time，RTT)及确认(ACK)报文，通过RTT报文可以获取到网络传输时延，通过ACK报文可以计算出网络丢包，也就是说，可以计算出网络的负载信息。
进一步地，移动终端100还可以基于网络环境的状态信息确定发送策略。其中，发送策略可以是，基于网络环境的状态信息中时延和负载的高低将第一类型音频数据流和/或第二类型音频数据流进行打包发送。
示例性的，若移动终端100判断时延较小且稳定，例如，移动终端可以计算预设历史时间段内的时延，若该预设历史时间段内的时延均值小于第一阈值(例如，10ms)，则可以认为时间较小且稳定。此时，移动终端可以将第一类型音频数据流和/或第二类型音频数据流进行打包发送，例如，移动终端100可以通过每10ms发送两帧第二类型音频数据(例如，低时延音频数据)，和/或每20ms发送一帧第一类型音频数据(例如，普通音频数据)的方式向第一设备200发送音频数据流。若时延均值小于第二阈值(例如，5ms)，则移动终端可以通过每5ms发送一帧第二类型音频数据(例如，低时延音频数据)，和/或每20ms发送一帧第一类型音频数据(例如，普通音频数据)的方式向第一设备200发送音频数据流。
若移动终端100判断时延较差且不稳定，例如，若时延大于第三阈值(例如，20ms)，此时，移动终端100如果每5ms发送一帧第二类型音频数据，则第一设备200无法稳定的收到音频数据，由此导致播放也不连续。因此，移动终端100可以通过每20ms发送四帧第二类型音频数据和/或一帧第一类型音频数据的方式向第一设备200发送音频数据流。
步骤107，第一设备200接收移动终端100发送的音频数据流，并播放音频数据流。
具体的，第一设备200接收到移动终端100发送的音频数据流后，可以判断该音频数据流的类型。
若第一设备200判断该视频数据流为第一类型(例如，普通音频数据流)，则根据与第一类型音频数据流对应的的时间间隔(例如，20ms)进行播放。
若第一设备200判断该视频数据流为第二类型(例如，低时延音频数据流)，则根据与第二类型音频数据流对应的的时间间隔(例如，5ms)进行播放。
现结合图3对本申请跨设备音频播放方法进行说明。如图3所示，移动终端100包含应用程序模块310、音频数据流处理模块320及音频数据流发送模块330。其中，应用程序模块310用于启动相应的应用程序，使得应用程序可以生成相应的音频数据流，应用程序模块310可以包括一个或多个应用程序，示例性的，应用程序模块310包括应用程序311及应用程序312，例如，应用程序311可以是游戏，应用程序312可以是音乐。当用户点击应用程序的图标，以启动应用程序后，例如，用户启动应用程序311和应用程序312后，响应于用户的操作，应用程序311可以生成第二类型音频数据流，应用程序312可以生成第一类型音频数据流。音频数据流处理模块320可以用于对应用程序模块310生成的音频数据流进行处理，例如，可以将音频数据流按照预设的时间间隔向音频数据流发送模块330发送，示例性的，音频数据流处理模块320可以对第一类型音频数据流进行混音及音效等处理，并按照每20ms一帧第一类型音频数据的时间间隔向音频数据流发送模块330发送第一类型音频数据流，以及每5ms一帧第二类型音频数据的时间间隔向音频数据流发送模块330发送第二类型音频数据流。音频数据流发送模块330接收到音频数据流处理模块320发送的音频数据流后，基于当前的发送策略向第一设备200发送音频数据流。其中，当前的发送策略可以基于当前的网络环境信息(例如，时延)确定。可以理解的是，音频数据流处理模块320在发送音频数据流之前，还可以对音频数据流进行标识，例如，将第一类型音频数据流标识为第一类型，将第二类型音频数据流标识为第二类型。
第一设备200包括音频数据流接收模块340、音频数据流处理模块350及音频数据流播放模块360。音频数据流接收模块340用于接收移动终端100中音频数据流发送模块330发送的音频数据流。当音频数据流接收模块340接收到音频数据流后，可以对音频数据流的类型进行识别，由此可以区分音频数据流是第一类型或第二类型，并将音频数据流发送给音频数据流处理模块350。音频数据流处理模块350接收到音频数据流接收模块340发送的音频数据流后，对第一类型音频数据流进行混音及音效处理，并将第一类型音频数据流按照每20ms一帧的时间间隔向音频数据流播放模块360发送，以及将第二类型音频数据流按照每5ms一帧的时间间隔向音频数据流播放 模块360发送。音频数据流播放模块360接收到频数据流处理模块350发送的音频数据流后，将第一类型音频数据流按照每20ms一帧的时间间隔进行播放，将第二类型音频数据流按照每5ms一帧的时间间隔进行播放，由此可以完成移动终端100与第一设备200之间的音频共享，并可以实现音频数据流的无损传输，保证音频数据流的音质，提高用户的体验。
