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，包括但不限于对多个实施例的组合，都属于本公开保护的范围。
本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
随着移动互联网技术的不断发展，人们的日常生活已经高度信息化，而直播技术是解决人们在不同地理空间上异地接收直播地信息的一种高效手段。近年来兴起的网络直播，更是给人们的娱乐生活增加了很多乐趣，收到了人们的追捧。大量主播纷纷加入了网络直播的行列。而通过移动设备来进行直播，以其简便性受到了很多主播的青睐。但是，随着观众对于直播质量要求的不断提高，主播在进行直播的时候，需要添加直播背景音乐。
面对这种需求，对于大多数主播来说，只能够通过购置一套专业的直播设备，包括：台式电脑、专业声卡、若干个中间转换器/衔接器等专业直播辅助设备来实现直播中的直播背景音处理需求。
图1为本公开实施例提供的现有室内主播使用的直播设备套件结构示意图。如图1所示，直播设备套件包括：移动终端101、中间衔接器102、中间转换器103、声卡104、台式电脑105。
其中，移动终端101中安装有直播应用。
中间衔接器102用于解决移动终端101在长时间直播时，充电接口被数据线占用而无法充电的问题。
中间转换器103用于将台式电脑105中的特效数据转接到移动终端101中，并且连接耳机后可以给客户提供耳返功能，还能够解决声卡104只能单路输出而不能反向接收直播应用输出的音频数据的问题。
声卡104与麦克风连接，实现将音频模拟信号转换为数字信号，输入台式电脑105中进行各种音效处理。
但是，图1所示的方式造成了直播成本的提高，需要配置多个辅助设备，而绝大多数主播不具备专业技术，无法自己去配置这一套设备，因此还需要配备专门的技术人员团队来构建、运营和维护这套专业直播设备，这些都使得本已通过手机等移动终端降低了的直播门槛，又被提高了起来。
并且，由于连接了多个设备，使得整套直播设备的稳定性容易受到各种因素的影响，任何一个设备的接插件插口出现问题，或者线路由于某种原因断路，都会使得系统无法工作。
基于上述技术问题，本申请的发明构思旨在：
通过一个用户端直接让主播在直播的时候在通过屏幕快速简便地将所需要的音频添加到直播的音频流中即设置直播背景音乐。使得直播无需多个设备，仅用一个小型设备就能完成直播背景音处理，也无需专业技术人员团队参与运维，主播一人即可在直播时实时选择并添加音频如背景音乐。
下面结合附图对本申请提供的直播背景音处理方法进行详细介绍。
参考图2，图2为本公开实施例提供的直播背景音处理方法的流程示意图一。本实施例的方法应用在用户端中，用户端的实现形式包括具有直播功能的设备，该具有直播功能的设备包括但不限于：直播一体式终端、移动终端和计算机设备，用户可以通过该直播一体式终端或移动终端直接完成直播，无需使用其它配套设备来对直播的音频或视频进行额外的处理。
该直播背景音处理方法包括：
S201：在满足预设显示条件时，在显示屏上显示背景音操作控件。
在本实施例中，用户端包括：主控制器以及音频处理器，在主控制器上安装有直播应用以及音乐播放应用。
在本步骤中，预设显示条件包括：检测到摄像设备开启指令、检测到直播终端按预设运动方式进行运动(如摇一摇、圆周运动、翻转运动等)、接收到预设语音指令和接收到预设按钮或开关控件对应的开启指令中的至少一种。
值得说明的是，显示屏的类型可以是触控屏或非触控屏。
具体的，例如，用户通过点击显示在直播界面上的快捷控件，来显示背景音操作控件。
在一种可能的设计中背景音操作控件的显示方式包括：分屏，和/或，悬浮窗显示。
在本实施例中，用户端上包括至少一个显示屏。在一种可能的设计中，用户端可以通过扩展接口连接多个外接显示屏，扩展接口包括无线接口和有线接口。
在一种可能的设计中，当用户端的显示屏数量大于1个时，背景音操作控件显示在非直播界面所在的显示屏上。
S202：响应于用户对背景音操作控件的操作指令，将音乐播放应用中对应的第一音频码流发送到音频处理器中。
在本步骤中，对背景音操作控件的操作指令包括：暂停、播放、上一曲、下一曲、歌单、列表或歌单循环播放、顺序播放、音乐搜索、歌词搜索、排行榜单搜索等操作中的至少一个。
具体的，背景音操作控件可以作为音乐播放应用的显示媒介，直接将音乐播放应用的操作界面直接复制投影到背景音操作控件的预设显示区域上。这样主播就可以直接像操作音乐播放应用一样，搜索需要的背景音乐，进行播放、暂停等操作，或者在预设歌单中选择播放 列表，然后选择播放方式，如：按播放列表顺序播放，随机播放，列表循环播放，单曲循环播放等。
需要说明的是，在现有技术中，当一个终端上安装有多个应用程序，且若存在多个应用程序同时开启时都需要使用相同的接口或外接设备的情况下，这些应用程序就会产生冲突。如在手机直播时，直播应用需要占用耳机接口或扬声器，此时若想在手机终端上打开音频播放应用，由于音频播放应用也需要用到扬声器或耳机接口，这就使得两个应用产生了冲突，若用户执意打开音频播放应用则直播应用将被迫关闭。
现有技术的这个问题就使得主播无法直接在手机或其它移动终端上直接打开音频播放应用来进行背景音乐的播放。而主播们解决此问题，一般是需要另一个音乐播放设备在直播环境中播放音乐，使得麦克风采集到直播环境中的音乐声，从而将其加入到直播应用的输入音频码流中。
或者是如图1所示通过外接声卡104和中间转换器103的形式，利用台式电脑105开启音乐播放应用，其产生的音频码流输入到外置独立的声卡104当中，而麦克风也不是直接与手机或移动终端101连接，而是与声卡104连接，以便于声卡104将音乐播放应用产生的音频码流与麦克风采集到的声音码流进行合成。
显然上述现有技术是通过将直播应用与音乐播放应用分置于两个不同设备中，再附加中间连接设备，才能解决两个应用同时开启时的资源占用矛盾。但是这样也就大大增加了直播成本和直播技术门槛。
而本实施例却是一反常态，打破了两个应用不能安装在同一设备上的技术壁垒，将直播应用与音乐播放应用一同安装在同一个终端上，但是在直播时音乐播放应用的开启和操作方式，却与在非直播时的方式不同。通过背景音操作控件来调用音乐播放应用，让原本音乐播放应用开启时需要占用耳机接口、扬声器等外设资源，转为占用背景音操作控件所对应的终端设备中的音频处理器资源，该音频处理器资源可以是实体的硬件设备如音频处理芯片对应的IO管脚接口，也可以是虚拟声卡、虚拟耳机、虚拟扬声器等虚拟资源。
需要说明的是，虚拟资源需要由主控制器通过专门的接口程序或应用模块来实现，本领域技术人员可以根据实际情况进行选择，本申请不做限定。
通过可视化的背景音操作控件以及音频处理器的结合，得以实现省去了台式电脑、外置独立声卡、中间转换器、中间衔接器等等外部辅助直播设备，既使得直播时添加背景音乐的简单快捷，又降低了设备成本，还无需依靠专业的技术人员团队支持，主播一人便可轻松直播。
S203：音频处理器将第一音频数据流与第二音频码流进行汇流合成，以确定直播应用的输入音频码流。
在本步骤中，第二音频码流包括用户端通过音频采集装置接收到主播所发出的声音信号，和/或，直播环境中的声音信号。
在本实施例中，利用预设合成算法，将第一音频数据流与第二音频码流合成为输入音频码流；
直播应用接收输入音频码流，并对输入音频码流进行编码，以确定输出音频码流；
将输出音频码流从网络接口中发送到网络服务器中，以使网络服务器将输出音频码流发送给各个观众所使用的直播观看终端。
即直播应用将输入音频码流编码后，通过网络传输给直播平台服务器，再由直播平台服务发送给各个观众。
图3为本公开实施例提供的用户端处理背景音频码流的示意图。如图3所示，用户端300中包括主控制器31和音频处理器32，其中，主控制器31中安装了直播应用311和音乐播放应用312。在开启了直播应用后，用户通过点击快捷键打开背景音操作控件，以此调用音乐播放应用312，并且，用户通过操作背景音操作控件，从音乐播放应用312中选择作为背景音乐播放的音频，音乐播放应用312产生连续的音频码流即第一音频数据流，输入到音频处理器32中。
音频处理器32还与用户端300的各个音频采集接口连接(如USB(Universal Serial Bus，通用串行总线)音频输入接口，3.5mm接口麦克风音频输入接口，卡农头接口麦克风音频输入接口)，以接收各个音频采集设备所接收到的主播音频或主播所处环境的音频即第二音频码流。
音频处理器32将所接收到的第一音频码流和第二音频码流，输入到预设合成算法模型中，以确定合成音频码流，作为直播应用311的输入音频码流。
需要说明的是，本领域技术人员可以根据实际需要选择具体的预设合成算法模型，本申请不做限定。
本公开实施例提供的直播背景音处理方法，首先在满足预设显示条件时，在显示屏上显示背景音操作控件，然后响应于用户对背景音操作控件的操作指令，将音乐播放应用中对应的第一音频码流发送到音频处理器中，最后音频处理器将第一音频数据流与第二音频码流进行汇流合成，以确定直播应用的输入音频码流。第二音频码流包括用户端通过音频采集装置接收到主播所发出的声音信号，和/或，直播环境中的声音信号。本公开实施例通过，解决了现有技术在面对高质量的直播需求时，存在只能够依赖复杂的专业设备和专业技术人员团队来添加背景音的技术问题。达到了主播在直播终端上即可便捷快速地在直播音频流中添加背景音的技术效果，降低了直播的成本和技术门槛，提高了用户的使用体验感。
为了进一步说明S201中的分屏显示和悬浮窗显示背景音操作控件，下面以两个具体的实施例来进行分别说明。
参考图4，图4为本公开实施例提供的直播背景音处理方法的流程示意图二。本实施例的方法应用在用户端中，用户端的实现形式包括具有直播功能的设备，该具有直播功能的设备包括但不限于：直播一体式终端、移动终端和计算机设备，用户可以通过该直播一体式终端或移动终端直接完成直播，无需使用其它配套设备来对直播的音频或视频进行额外的处理。
该直播背景音处理方法包括：
S401：获取所述用户发出的开启指令。
在本步骤中，开启指令包括：点击直播界面上的背景音开启的快捷键按钮或控件。
在本实施例中，用户在启动用户端上的直播应用后，用户点击开始直播，则直播应用开启用户端上的摄像头。而当用户端检测到摄像头被打开后，则在显示屏的边缘显示分屏控件。
在一种可能的设计中，背景音开启控件包括用于分屏显示的悬浮窗控件即分屏控件，则用户点击分屏控件即可被用户端的主控制器检测到开启指令。
S402：根据开启指令所指示的预设显示方式，在直播界面上同时显示背景音操作控件。
在本实施例中，预设显示方式包括：分屏显示方式。
具体的，将所述用户端的至少一个显示屏分割为直播界面区以及背景音操作区。
需要说明的是，直播界面区以及背景音操作区的边界包括：直线边界和/或曲线边界。
图5a-5c为本公开实施例提供的一种用户端的显示屏分屏显示背景音操作区的示意图。如图5a所示，用户在用户端500的显示屏上点击“分屏控件”后，显示屏就会分为直播界面区510和背景音操作区520。
需要说明的是，背景音操作控件即背景音操作区520所显示的内容包括：所述音乐播放应用的操作界面的全部或部分内容。
用户端500通过后台控制算法，将背景音操作区520的各个控件与音乐播放应用的操作界面进行映射对应。
如图5a所示，背景音操作区520中包括：
歌单子控件521，用于切换歌单列表；
搜索子控件522，用于搜索歌曲；
菜单子控件523，用于显示音乐播放应用的更多功能选项；
操作子控件524，用于实现播放、暂停、停止、上一曲、下一曲等操作。
当然可以理解的是，背景音操作区520还可以包括播放进度，音量控制，歌名，演唱者，作词/曲人等等信息控件。需要说明的是，本领域技术人员可以根据实际情况选择背景音操作区520的布局及实现样式，本申请不做限定。
在一种可能的设计中，分屏也可以是左右分屏，如图5b所示，分屏后直播界面区510和背景音操作区520所占显示屏的比例，可以根据实际需要进行调整，如：背景音操作区520占30％～50％。
需要说明的是，分屏后直播界面区510和背景音操作区520的边界也可以是直线与曲线所围成的任意几何形状。如图5c所示，背景音操作区520可以有多个，各个子控件分布在多个背景音操作区520中。
S403：获取用户对背景音操作控件的操作指令。
在本实施例中，用户对背景音操作控件的操作指令包括：用户在背景音操作区520中的各类操作指令，以及对背景音操作区520边界的操作指令。
用户在背景音操作区520中的各类操作指令，包括：暂停、播放、上一曲、下一曲、歌单、列表或歌单循环播放、顺序播放、音乐搜索、歌词搜索、排行榜单搜索中的至少一个。这些操作指令的具体作用，是在音乐播放应用中选择作为直播背景音的音频数据或音频码流。
对背景音操作区520边界的操作指令，包括：用户按预设方式改变直播界面区以及背景音操作区相邻的边界，以改变背景音操作控件的显示状态，显示状态包括：开启或关闭状态、扩大或缩小背景音操作区。
具体的，如图5a和5b所示的背景音操作区520，用户可以通过点击边界上至少一点或点击所述边界上至少一个直线段，来实现收起背景音操作区520或改变背景音操作区520所占的比例大小。
在一种可能的设计中，用户按住边界上的至少一点不放，然后进行上下或左右滑动，即可实现改变背景音操作区520所占的比例大小。如图5a中，用户按住边界上的一点，然后进行上下或左右滑动，即可实现改变背景音操作区520所占的比例大小。
这里需要说明的是，左右滑动时，也可以理解为用户手指沿着边界所指示的路径进行滑动，从左到右滑动时，代表扩大背景音操作区520所占的比例大小；从右到左滑动时，代表缩小背景音操作区520所占的比例大小。
如图5c，这种边界既有直线，又有曲线的情况，可以设定不同的操作方式，如当用户按住边界的直线段，以垂直于直线段的方向滑动，则在垂直于直线段的方向扩大或缩小背景音操作区520。
当用户按住曲线边界，并在曲线上被按住的点所在的切线方向，或者切线的垂直方向上滑动时，按照对应方向来扩大或缩小背景音操作区520。
当用户沿曲线边界或直线边界滑动时，也可实现改变背景音操作区520所占的比例大小。
S404：将音乐播放应用中对应的第一音频码流发送到音频处理器中。
用户在背景音操作区520中选中并开始播放某个音频时，音乐播放应用中对应的将该音频数据播放时产生的第一音频码流发送到音频处理器中。
S405：音频处理器将第一音频数据流与第二音频码流进行汇流合成，以确定直播应用的输入音频码流。
在本步骤中，第二音频码流包括用户端通过音频采集装置接收到主播所发出的声音信号，和/或，直播环境中的声音信号。
本步骤的具体原理及名词解释参考S203，在此不再赘述。
本公开实施例提供的直播背景音处理方法，首先在满足预设显示条件时，在显示屏上以分屏的形式显示背景音操作控件，然后响应于用户对背景音操作控件的操作指令，将音乐播放应用中对应的第一音频码流发送到音频处理器中，最后音频处理器将第一音频数据流与第二音频码流进行汇流合成，以确定直播应用的输入音频码流。第二音频码流包括用户端通过音频采集装置接收到主播所发出的声音信号，和/或，直播环境中的声音信号。本公开实施例解决了现有技术在面对高质量的直播需求时，存在只能够依赖复杂的专业设备和专业技术人员团队来添加背景音的技术问题。达到了主播在直播终端上即可便捷快速地在直播音频流中添加背景音的技术效果，降低了直播的成本和技术门槛，提高了用户的使用体验感。
图6为本公开实施例提供的直播背景音处理方法的流程示意图三。本实施例的方法应用在用户端中，用户端的实现形式包括具有直播功能的设备，该具有直播功能的设备包括但不限于：直播一体式终端、移动终端和计算机设备，用户可以通过该直播一体式终端或移动终端直接完成直播，无需使用其它配套设备来对直播的音频或视频进行额外的处理。
该直播背景音处理方法包括：
S601：获取所述用户发出的开启指令。
本步骤的具体原理及名词解释参考S401，在此不再赘述。
S602：根据开启指令，以悬浮窗的预设显示方式，在直播界面上同时显示背景音操作控件。
在本实施例中，背景音操作控件以悬浮窗的形式叠加在直播界面上显示。
图7a-7e为本公开实施例提供的一种以悬浮窗的形式显示背景音操作控件的示意图。如图7a所示，用户在用户端700上点击了“背景音乐”快捷键后，在直播界面上叠加显示背景音操作控件即悬浮窗710。
悬浮窗710中包括：歌曲图标711、搜索控件712、菜单控件713、播放方式控件714以及缩放控件715。
在一种可能的设计中，歌曲图标711用于显示最近一次播放的歌曲的封面图片。
搜索控件712，用于搜索歌曲、歌词、歌手、专辑、歌单、排行榜等音频相关信息，以供用户筛选出直播时需要播放的背景音乐。
S603：响应于用户对背景音操作控件的操作指令，将音乐播放应用中对应的第一音频码流发送到音频处理器中。
在本实施例中，操作指令是指用户对悬浮窗上各个子控件的操作，具体的，如图7a-7d所示：
当用户在图7a所示的悬浮窗710上点击了缩放控件715时，悬浮窗710就只显示歌曲图标711，以减少悬浮窗710对直播界面的视觉影响。
当用户在图7a所示的悬浮窗710上点击了菜单控件713时，悬浮窗710将转变为图7b所示的形式，即在下方显示歌单列表，用户再选中了某个歌单后，如歌单1，则开始播放该歌单中的歌曲，如图7c所示，该歌曲可以是随机从歌单中选择的，也可以是该歌单中预设位置的歌曲，如第一首歌曲，也可以是该歌单最近一次所播放的歌曲。
此时，若用户再次点击菜单控件713时，歌单列表将会被收起，如图7d所示。
当用户在搜索控件712上输入了搜索关键字/词，并指示执行搜索后(如按回车，或点击“放大镜状按钮”)，如图7e所示，在悬浮窗710的下方将展开搜索结果列表，用户点击任意一个搜索结果，则切换播放该搜索结果所对应的歌曲。
当悬浮窗710开始播放歌曲后，用户端的主控制器将音乐播放应用中对应的第一音频数据流发送给音频处理器。
还需要说明的是，悬浮窗也可以设计为显示与音乐播放应用相同的操作界面，以使得主播不用改变对音乐播放应用的使用习惯，使用起来更加容易上手，提高用户体验。
S604、音频处理器将第一音频数据流与第二音频码流进行汇流合成，以确定直播应用的输入音频码流。
在本步骤中，第二音频码流包括用户端通过音频采集装置接收到主播所发出的声音信号，和/或，直播环境中的声音信号。
本步骤的具体原理及名词解释参考S203，在此不再赘述。
