图1为本公开实施例提供的一种投屏方法的流程图，本实施例可适用于投屏情况，该方法可以由设置于发送端的投屏装置来执行，该发送端可以是移动终端(如：智能手机或者平板电脑)或者可穿戴设备(如：智能手表、智能手环、智能眼镜或者头戴VR终端等)。如图1所示，该方法包括如下步骤：
S110，基于设定账号登录至投屏服务器。
其中，设定账号可以是用户在投屏服务器中注册的账号，投屏服务器可以理解为用于实现投屏功能的服务器。本实施例中，用户通过发送端中安装的投屏应用程序(Application，APP)或者通过浏览器投屏网页输入设定账号及登录密码，从而登录至投屏服务器。发送端登录至投屏服务器后，还可以将所在的局域网地址上报至投屏服务器。
S120，基于发送端信息生成至少一种协议类型的推流地址，并将推流地址发送至投屏服务器。
其中，发送端信息包含局域网地址信息、发送端端口信息及音视频路径信息，即推流地址由局域网地址信息、发送端端口信息及音视频路径信息组成。至少一种协议类型可以包括流媒体传输协议(Hyper Text Transfer Protocol-Flash Video，HTTP-FLV)和实时消息传输协议(Real Time Messaging Protocol，RTMP)。这样可以使得支持HTTP-FLV协议或者RTMP协议的接收端均可以接收到发送端的音视频流，不受硬件及系统等的限制。
例如，发送端根据获取到的局域网地址信息、发送端端口信息及音视频路径信息生成推流地址，并将该推流地址发送至投屏服务器。
S130，根据推流地址将音视频流发送至目标接收端，使得目标接收端播放音视频流。
其中，目标接收端为采用设定账号登录至投屏服务器的终端，即目标接收端与发送端采用同一账号登录至投屏服务器，且目标接收端可以为一个或者多个。
本实施例中，若目标接收端点选了推流地址，发送端则根据该推流地址将音视频流发送至目标接收端，使得目标接收端播放音视频流，从而实现发送端将音视频流投屏至目标接收端。
例如，根据推流地址将音视频流发送至目标接收端的过程可以是：对发送 端执行录屏操作，获得音视频流；判断发送端与目标接收端是否处于同一局域网；若发送端与目标接收端处于同一局域网，则根据推流地址建立与目标接收端的数据通道，并通过数据通道将音视频流发送至目标接收端；若发送端与目标接收端不处于同一局域网，则将音视频流发送至投屏服务器，使得投屏服务器将音视频流转发至目标接收端。
其中，录屏操作可以理解为对当前屏幕播放的音视频进行录制，从而获得音视频流。
其中，判断发送端与目标接收端是否处于同一局域网的方式可以是：向目标接收端发送网络探索ping信息；若接收到目标接收端的反馈信息，则发送端与目标接收端是否处于同一局域网。
本实施例中，当发送端登录至投屏服务器后，投屏服务器向发送端发送ping指令，发送端根据ping指令ping接收端，若接收到目标接收端的反馈信息，则发送端与目标接收端处于同一局域网。
本实施例中，若发送端与目标接收端处于同一局域网，则发送端将音视频流通过建立的数据通道发送至目标接收端；若发送端与目标接收端不处于同一局域网，则发送端将音视频流发送至投屏服务器，使得投屏服务器将音视频流转发至目标接收端。
本公开实施例的技术方案，基于设定账号登录至投屏服务器；基于发送端信息生成至少一种协议类型的推流地址，并将推流地址发送至投屏服务器；其中，发送端信息包含局域网地址信息、发送端端口信息及音视频路径信息；当接收到目标发送端发送的投屏请求时，根据推流地址将音视频流发送至目标接收端，使得目标接收端播放音视频流。本公开实施例提供的投屏方法，可以实现投屏的通用性，不受硬件及系统等的限制。

S220，通过投屏请求向投屏服务器获取推流地址列表。
其中，推流地址为采用设定账号登录至投屏服务器的终端生成的。其中，投屏请求可以是通过浏览器网页发送，或者投屏APP发送。
本实施例中，通过投屏请求向投屏服务器获取推流地址列表的过程可以是：若接收端通过网页登录投屏服务器，则通过设定投屏网址向投屏服务器发送投屏请求，以获得推流地址列表。
其中，设定投屏网址可以是预先设定好的地址，例如：http://www.touping.com。本实施例中，投屏服务器接收到投屏请求后，确定接收端支持的通信协议，并同一账号对应的接收端支持的通信协议下推流地址列表发送至接收端。使得接收端选择其中一推流地址，以获取该推流地址对应的音视频流。即若接收端支持HTTP-FLV协议，则投屏服务器将HTTP-FLV协议下的推流地址列表发送至接收端；若接收端支持RTMP协议，则投屏服务器将RTMP协议下的推流地址列表发送至接收端。
例如，若接收端通过投屏APP登录投屏服务器，则通过检测用户触发的投屏请求模块向，以获得推流地址列表投屏服务器发送投屏请求，以获得推流地址列表。
S230，根据用户选择的推流地址获取音视频流，并播放音视频流。
例如，用户从推流地址列表中选择其中一推流地址，获取该推流地址对应的发送端对应的音视频流，并播放音视频流。
例如，根据用户选择的推流地址获取音视频流，并播放音视频流的方式可以是：根据用户选择的推流地址确定目标发送端；若接收端与目标发送端处于同一局域网，则接收目标发送端发送的音视频流；若接收端与目标发送端处于不同的局域网，则接收投屏服务器发送的音视频流。
本实施例中，当用户选择其中一个推流地址后，将生成该推流地址的发送端确定为目标发送端，若接收端与目标发送端处于同一局域网，则接收目标发送端通过数据通道发送的音视频流，若接收端与目标发送端处于不同的局域网，则接收投屏服务器转发的音视频流。
本公开实施例的技术方案，基于设定账号登录至投屏服务器；通过投屏请求向投屏服务器获取推流地址列表；其中，推流地址为采用设定账号登录至投屏服务器的发送端生成的；根据用户选择的推流地址获取音视频流，并播放音视频流。本公开实施例提供的投屏方法，可以实现投屏的通用性，不受硬件及系统等的限制。

例如，在接收发送端发送的推流地址以及至少一个接收端发送的投屏请求之后，还包括：若接收到发送端发送的音视频流，则将音视频流转发至至少一个接收端进行播放。
本实施例中，若接收端与发送端不在同一局域网，则发送端将录屏到的音视频流发送是投屏服务器，使得投屏服务器将该音视频流转发至接收端。
本实施例的技术方案，检测到发送端及至少一个接收端基于同一设定账号登录至投屏服务器时，接收发送端发送的推流地址以及至少一个接收端发送的投屏请求；根据投屏请求将推流地址发送至至少一个接收端，使得发送端将播放的音视频流投屏至至少一个接收端进行播放。可以实现投屏的通用性，不受硬件及系统等的限制。
