实施例一
图1为本公开实施例一所提供的一种音频播放方法流程示意图，本公开实施例适用于音频播放的场景，例如是在视频播放的过程中切换音频数据的情形。该方法可以由配置于客户端的音频播放装置来执行，该装置可以通过软件和/或硬件的形式实现，该装置可配置于电子设备中，例如配置于移动终端或服务器设备中。
如图1所示，本实施例提供的音频播放方法，包括：
S110、在当前音视频数据播放的过程中，当获取到音频数据切换指令时，向服务端请求与所述音频数据切换指令相关联的目标音频数据。
在本实施例中的音频播放方法可适用于多个视频应用平台，播放的当前音视频数据中视频数据和音频数据是相互独立的两组数据。视频数据和音频数据在播放过程中，可以通过视频数据和音频数据被接收到时的时间戳信息，或是音频数据和/或视频数据的关键帧信息进行音视频数据的播放同步。其中，关键帧是音视频数据的压缩编码中最为重要的帧，例如视频数据压缩编码中的I帧。
在当前音视频数据播放的过程中，当获取到音频数据切换指令时，客户端则会向服务端发出请求，以获取与音频数据切换指令相关联的目标音频数据。目标音频数据也就是音频切换的目标对象，将当前音视频数据中的初始音频数据切换为目标音频数据。在获取目标音频数据的过程中，会通过服务端提供的目标音频数据的数据获取链接，与服务端之间建立连接通道；然后，通过该连接通道获取目标音频数据并进行缓存，等待确定播放时间之后进行播放。目标音频数据与初始音频数据是与当前音视频数据中视频数据相关联的不同音频内容的数据。在一些场景中，初始音频数据与目标音频数据可以是与同一个视频数据匹配的不同语种的配音音频数据。例如，一个电影视频，包含有与之匹配的汉语、英语、法语及日语等不同语种的配音音频数据。该电影的观众可以在观看电影的过程中，切换任一语种的音频数据。或者，一些动画片的配音有普 通话版本以及方言版本，观众也可以选择不同版本的音频数据进行播放，并且在播放的过程中切换不同版本的配音音频数据。
S120、根据所述当前音视频数据中的视频数据的关键帧信息确定所述目标音频数据的播放时刻。
在进行音视频同步时，通常可以将视频同步到音频上，就是以音频的播放速度为基准来同步视频。也可以将音频同步到视频上，就是以视频的播放速度为基准来同步音频。或者，还可以将视频和音频同步到外部的时钟上，选择一个外部时钟为基准，视频和音频的播放速度都以该时钟为标准。在本实施例中，考虑到音频会被切换的不稳定性，选择将音频同步到视频的同步策略。
在已缓存未播放的视频数据中，确定与获取到音频数据切换指令的时刻对应的视频图像帧相邻的且未播放的视频关键帧，也就是按照多个视频图像帧的时间顺序，在与获取到音频数据切换指令的时刻对应的视频图像帧之后的第一个视频关键帧；然后，将视频关键帧对应的视频播放时间作为目标音频数据的播放时刻。从而，可以在用户的音频数据切换指令发出后，很快进行响应，执行音频的切换操作。
S130、在所述播放时刻将所述当前音视频数据中的初始音频数据切换为所述目标音频数据并进行播放。
在确定好的目标音频数据的播放时刻播放目标音频数据以替代初始音频数据，在消耗新的目标音频数据的同时，还需要清除音频数据缓存区域中，在该播放时刻之后的初始音频数据的已缓存数据，以避免初始音频数据在该播放时刻之后继续播放。从而实现了目标音频数据与初始音频数据的播放衔接，在此过程中，视频数据的播放并没有停止，因此不会出现黑屏或是卡顿的问题。
本公开实施例的技术方案，可以通过在当前音视频数据播放的过程中，当获取到音频数据切换指令时，向服务端请求与音频数据切换指令相关联的目标音频数据；根据当前音视频数据中的视频数据的关键帧信息确定目标音频数据的播放时刻；在播放时刻将当前音视频数据中的初始音频数据切换为目标音频数据并进行播放。即将播放的音视频数据中的音频数据和视频数据相互独立，使两个相互独立的数据依据视频数据的关键帧信息同步播放。本公开实施例的技术方案解决了相关技术中切换音频时需要切换包含另一不同音频的视频导致消耗过多流量且视频播放衔接不流畅的问题，实现了能够在播放视频的过程中仅切换音频数据，不会产生冗余的视频内容下载，并且使视频流畅的播放，避免了视频播放界面的黑屏以及卡顿等现象。
实施例二
本公开实施例与上述实施例中所提供的音频播放方法中多个方案可以结合。本实施例所提供的音频播放方法，描述了从当前音视频数据播放开始至音频数据被切换的过程。
图2为本公开实施例二所提供的一种音频播放方法的流程示意图。如图2所示，本实施例提供的音频播放方法，包括：
S210、根据用户的音视频数据获取指令，向服务端请求与所述音视频数据获取指令相关联的视频数据的数据获取链接以及视频数据对应的至少一个音频数据的数据获取链接。
在本实施例中的音频播放方法可适用于多个视频应用平台，播放的当前音视频数据中视频数据和音频数据是相互独立的两组数据。也就是说在音视频数据生产的过程中，音频数据与视频数据分别进行制作，一份视频内容对应的制作了多份音频内容，且每一份音频内容是不同的。例如，一个电影视频，对应的有与之匹配的汉语、英语、法语及日语等不同语种的配音音频数据。
用户在视频应用平台选择视频进行观看的时候，可以在平台搜索想观看的视频，或者观看视频应用平台推荐的视频。当用户确定观看的视频，即向视频应用客户端发出了音视频数据获取指令，视频应用客户端会根据音视频数据获取指令向服务端请求对应的音频数据与视频数据资源。服务端会反馈相应的音视频数据资源链接，包括一个视频数据获取链接，以及对应的至少一个音频数据的数据获取链接。
在以往的音视频数据中，音频数据是与视频数据融合在一起的，若一个影视作品有不同的配音版本，那么在服务端进行存储的便是相同视频内容、不同语言音频的视频文件，对服务端来说视频生产成本以及存储成本较大。而通过本实施例的技术方案，可以分别存储视频数据与音频数据，在视频播放时，根据用户的播放需求将对应的视频数据与音频数据组同步播放即可，大大减轻了服务端的视频生产成本以及存储成本，对服务端的运行更加友好。
S220、根据用户的初始音频数据确定指令，在所述至少一个音频数据中确定初始音频数据，并通过视频数据和初始音频数据分别对应的数据获取链接获取视频数据和初始音频数据作为当前音视频数据并进行播放。
在服务端提供了一个或多个的音频资源中，用户需要选择一个音频数据作为初始音频数据。当用户确定初始音频数据之后，即向客户端发出了初始音频数据确定指令。客户端便根据获取到的初始音频数据确定指令，在至少一个音频数据中确定初始音频数据，并基于对应的数据获取链接与服务端分别建立音视频数据传输链路，以获取视频数据和初始音频数据作为当前音视频数据并进 行播放。
S230、在当前音视频数据播放的过程中，当获取到音频数据切换指令时，向服务端请求与所述音频数据切换指令相关联的目标音频数据。
当前播放的音视频数据中，若视频数据对应有一个以上的音频数据，用户便可以在当前音视频数据播放的过程中发出音频数据切换指令，以切换不同的音频数据。例如，初始音频数据为视频数据的英语配音音频，用户希望切换到汉语配音的音频，那么汉语配音音频数据即为目标音频数据。
S240、根据所述当前音视频数据中的视频数据的关键帧信息确定所述目标音频数据的播放时刻。
在本实施例中，选择将音频同步到视频的同步策略。在已缓存未播放的视频数据中，确定与获取到音频数据切换指令的时刻对应的视频图像帧相邻的且未播放的视频关键帧；然后，将视频关键帧对应的视频播放时间作为目标音频数据的播放时刻。从而，可以在用户的音频数据切换指令发出后，很快进行响应，执行音频的切换操作。
S250、在所述播放时刻将所述当前音视频数据中的初始音频数据切换为所述目标音频数据并进行播放。
本公开实施例的技术方案，通过以视频数据和音频数据相互独立的方式为用户提供音视频资源，根据用户的选择同步播放相应的音频数据与视频数据。并且，在当前音视频数据播放的过程中，当获取到音频数据切换指令时，向服务端请求与音频数据切换指令相关联的目标音频数据；根据当前音视频数据中的视频数据的关键帧信息确定目标音频数据的播放时刻；在播放时刻将当前音视频数据中的初始音频数据切换为目标音频数据并进行播放。可以使用户在观看视频的过程中无需暂停视频，便可以切换不同的音频数据。本公开实施例的技术方案解决了相关技术中切换音频时需要切换包含另一不同音频的视频导致消耗过多流量且视频播放衔接不流畅的问题，实现了能够在播放视频的过程中仅切换音频数据，不会产生冗余的视频内容下载，并且使视频流畅的播放，避免了视频播放界面的黑屏以及卡顿等现象，使用户有了更加好的视频消费体验。
