S120、若检测到当前网络环境满足投屏切换条件，则将所述第一投屏方式切换为第二投屏方式。
S130、采用所述第二投屏方式进行投屏。
在本实施例中，第一投屏方式是指投屏关联设备当前所使用的投屏方式。第二投屏方式 是指投屏关联设备切换后的投屏方式。第一投屏方式或者第二投屏方式的具体投屏方式在此不做限定。示例性的，具体投屏方式包括但不限于局域网投屏和互联网投屏，其中，局域网投屏为投屏关联设备通过局域网实现的投屏方式，即一个投屏关联设备通过局域网将投屏数据传输至其他投屏关联设备的投屏方式；互联网投屏为投屏关联设备通过互联网实现的投屏方式，即一个投屏关联设备通过局域网将投屏数据传输网络服务器，通过网络服务器将投屏数据传输至其他投屏关联设备的投屏方式。例如，局域网投屏和互联网投屏分别可以包括有线投屏和/或无线投屏，其中，可以通过HDMI线等实现有线投屏；无线投屏可以为WIFI投屏、云投屏等。投屏关联设备是指可以进行投屏的关联电子设备，投屏关联设备可以包括投屏发送端和投屏接收端，关联电子设备的数量可以为两个或者两个以上，在此不做限定。
示例性的，投屏关联设备可以包括第一电子设备和第二电子设备，第一电子设备与第二电子设备通信连接。其中，第一电子设备与第二电子设备用于将一个电子设备与另一个电子设备进行区分。第一电子设备和第二电子设备两者都是电子设备，但其不是同一电子设备。例如，本公开中的第一电子设备可以为手机终端，作为投屏发送端；第二电子设备可以为电视，作为投屏接收端；例如，本公开中的第一电子设备可以为计算机等的终端设备，第二电子设备可以为手机、计算机等的终端设备，且第二电子设备的数量可以是为多个。
在本实施中，投屏关联设备的当前网络环境是指投屏关联设备在网络环境的检测时刻的网络通信环境。投屏关联设备的不同网络环境可支持不同的投屏方式，例如，投屏关联设备接入局域网内，可支持局域网投屏方式，投屏关联设备接入互联网内，可支持互联网投屏方式，例如云平台方式。
投屏关联设备通过第一投屏方式进行投屏，投屏过程中，检测多个投屏关联设备的当前网络环境，其中，第一投屏方式可以是在多个投屏方式中随机选择的一种投屏方式，或者，可以是通过其他投屏方式切换到的投屏方式，或者，可以是在投屏启动时刻，人工选择的一种投屏方式，对此不作限定。投屏关联设备中的任一电子设备，在采用第一投屏方式的投屏过程中，检测多个投屏关联设备的当前网络环境。例如，该电子设备实时进行当前网络环境的检测，还可以是周期性的进行当前网络环境的检测。在检测到投屏关联设备的当前网络环境满足投屏切换条件的情况下，进行投屏关联设备的投屏方式的切换，其中，投屏切换条件是指预先设置的投屏关联设备进行投屏方式切换的条件。
需要说明的是，通过检测投屏关联设备的当前网络环境，可以得知投屏关联设备的通信方式、通信质量等网络环境信息，从而可以根据投屏关联设备的通信方式、通信质量等网络环境信息，判断是否满足投屏切换条件；在当前网络环境满足投屏切换条件的情况下，可以将投屏方式自动切换为与当前网络环境对应的投屏方式，提高了投屏关联设备与当前网络环境的适应性，从而保证了投屏质量，无感知切换，在不中断投屏过程的情况下进行自动切换，无需用户的等待过程。
示例性的，在第一电子设备与第二电子设备建立基于第一投屏方式的连接的情况下，第一电子设备和/或第二电子设备可以检测当前网络环境，在当前网络环境满足投屏切换条件的情况下，可以根据当前网络环境，建立第一电子设备与第二电子设备基于第二投屏方式的连接，并采用第二投屏方式进行投屏。
在一些实施方式中，第二投屏方式可以是根据当前网络环境实时确定的投屏方式，换而言之，第二投屏方式为与当前网络环境所适应的投屏方式，可以有效提高投屏关联设备与当前网络环境的适应性，从而保证了投屏质量。在一些实施方式中，第二投屏方式可以是用户预先指定的固定投屏方式。
在一些实施方式中，投屏切换条件为当前网络环境支持的第二投屏方式的优先级高于第一投屏方式的优先级。
可以理解的是，当前网络环境支持的第二投屏方式的优先级高于第一投屏方式的优先级，换而言之，投屏关联设备在进行投屏时，优先选取第二投屏方式，提升投屏质量。
在投屏之前，可以预先配置多种投屏方式，并对多种投屏方式设置优先级。设置优先级 的依据可以包括但不限于投屏稳定性、投屏费用、投屏质量、投屏速度等，在此不做限定。示例性的，若第二投屏方式的稳定性高于第一投屏方式，不会出现显示画面卡顿的情况，则设置第二投屏方式的优先级高于第一投屏方式的优先级；或者，若第二投屏方式的投屏费用低于第一投屏方式，不会产生流量费用，则设置第二投屏方式的优先级高于第一投屏方式的优先级；或者，若第二投屏方式的投屏速度高于第一投屏方式，投屏延迟小，则设置第二投屏方式的优先级高于第一投屏方式的优先级。例如，投屏方式的优先级可以是基于投屏稳定性、投屏费用、投屏质量、投屏速度的一项或多项设置的，对此不作限定。其中，投屏方式的优先级可根据用户需求进行更新，更新后的投屏方式优先级进行存储，便于在投屏切换的情况下进行调用。
例如，在采用第一投屏方式的投屏过程中，投屏关联设备可以检测投屏关联设备的当前网络环境，确定当前网络环境支持的投屏方式，在当前网络环境支持的第二投屏方式的优先级高于第一投屏方式的优先级的情况下，可以将投屏方式切换为优先级高的第二投屏方式，并根据第二投屏方式进行投屏，提升投屏质量。其中，当前网络环境支持的投屏方式可以是多种，在优先级高于第一投屏方式的优先级的情况下，可以是将当前网络环境支持的投屏方式中优先级最高的投屏方式确定为第二投屏方式。
在一些实施例中，第二投屏方式可以是投屏关联设备检测到的用户指定的投屏方式，换而言之，用户指定的投屏方式为优先级最高的投屏方式。可以理解的是，为了提升用户体验，投屏方式的优先级可以根据用户的需求进行定制。
在一些实施方式中，投屏切换条件包括：当前网络环境变化为不支持所述第一投屏方式的网络环境。
可以理解的是，在当前网络环境的通信质量差的情况下，例如通信连接断开、通信传输速率慢等情况，表明当前网络环境无法以第一投屏方式继续进行投屏，需要进行投屏方式的更换，以提高投屏质量。
例如，在采用第一投屏方式的投屏过程中，投屏关联设备可以检测投屏关联设备的当前网络环境，在当前网络环境不满足第一投屏方式的投屏条件的情况下，可以将投屏方式切换为第二投屏方式，并采用第二投屏方式进行投屏。其中，第二投屏方式可以是与当前网络环境支持的投屏方式中的一种，例如可以是当前网络环境支持的投屏方式中优先级最高的投屏方式。可以理解的是，当前网络环境不满足第一投屏方式的投屏条件，表明第一投屏方式所需的网络环境可能存在问题，可以更换其他网络环境下的投屏方式，以保证投屏质量。
示例性的，当前网络环境可以为WIFI投屏，在WIFI中断的情况下，投屏关联设备可以更换为其他网络连接，以保证投屏质量。其中，其他网络可以包括蜂巢式网络、卫星通讯等，在此不做限定。
需要说明的是，在切换为第二投屏方式的情况下，采用第二投屏方式进行投屏，并停止第一投屏方式的投屏过程。投屏关联设备可根据切换后的投屏方式进行投屏，例如，投屏发送端确定第二投屏方式下的投屏数据发送方式，并进行投屏数据的发送，投屏接收端确定第二投屏方式下的投屏数据接收方式，并接收投屏数据进行展示。此处对第二投屏方式的具体实现方式不作限定。
本公开实施例的技术方案，通过在采用第一投屏方式的投屏过程中，检测投屏关联设备的当前网络环境，若检测到当前网络环境满足投屏切换条件，则将第一投屏方式切换为第二投屏方式，采用第二投屏方式进行投屏。通过上述技术方案，实现了投屏关联设备投屏方式的自动切换，并将投屏方式自动切换为与当前网络环境对应的投屏方式，提高了投屏关联设备与当前网络环境的适应性。
图3为本公开实施例提供的一种投屏方法的流程示意图，本实施例的方法与上述实施例中提供的投屏方法中多个示例方案可以结合。本实施例提供的投屏方法进行了细化。例如，所述第二投屏方式为局域网投屏方式；所述投屏关联设备包括：投屏发送端与投屏接收端，所述投屏切换条件包括：所述投屏发送端与所述投屏接收端位于同一局域网内。
如图3所示，该方法包括：
S210、在采用第一投屏方式的投屏过程中，检测投屏关联设备的当前网络环境，其中，所述投屏关联设备包括：投屏发送端与投屏接收端。
S220、若所述投屏发送端与所述投屏接收端位于同一局域网内，则将投屏方式切换为局域网投屏方式。
S230、采用所述局域网投屏方式进行投屏。
在本实施例中，投屏发送端是指发送投屏数据的电子设备。投屏接收端是指接收并展示投屏数据的电子设备。其中，投屏数据可以包括但不限于图片、音频、视频等内容。局域网投屏方式是指利用局域网进行投屏显示的投屏方式，可以包括有线局域网投屏方式和无线局域网投屏方式，例如无线局域网投屏方式可以为WIFI投屏。可以理解的是，在利用局域网进行投屏的情况下，投屏发送端与投屏接收端位于同一局域网内。
例如，在采用第一投屏方式的投屏过程中，可以实时检测投屏发送端和投屏接收端的当前网络环境，在当前网络环境的检测结果为投屏发送端与投屏接收端位于同一局域网内的情况下，可以将投屏方式切换为局域网投屏方式。需要说明的是，局域网投屏方式具有延迟低、不消耗流量的特点，通过局域网投屏方式进行投屏，可以提升投屏质量并降低流量消耗。例如，局域网投屏方式的优先级高于第一投屏方式的优先级，或者，投屏关联设备的当前网络环境不支持第一投屏方式。示例性的，第一投屏方式可以是云投屏方式。
在一些实施方式中，检测投屏关联设备的当前网络环境，包括：基于局域网对投屏关联设备进行搜索；在同一局域网内搜索到全部的投屏关联设备的情况下，确定当前网络环境满足局域网投屏方式的投屏切换条件。
例如，投屏发送端搜索位于同一局域网内的电子设备，若搜索结果中包含与投屏发送端通过第一投屏方式连接的投屏接收端，则表明当前网络环境满足局域网投屏方式的投屏切换条件，进而可以建立投屏发送端与投屏接收端的局域网连接，并通过局域网进行投屏数据的传输，实现投屏。例如，投屏接收端搜索位于同一局域网内的电子设备，若搜索结果中包含与投屏接收端通过第一投屏方式连接的投屏发送端，则表明当前网络环境满足局域网投屏方式的投屏切换条件，进而可以建立投屏发送端与投屏接收端的局域网连接，并通过局域网进行投屏数据的传输，实现投屏。
在一些实施方式中，基于局域网对投屏关联设备进行搜索，包括：基于当前局域网发送搜索请求；接收当前局域网内设备反馈的设备信息，基于接收的设备信息验证当前局域网内的设备是否为投屏关联设备。
其中，设备信息是指设备的标识信息，具有唯一性。换而言之，在已知投屏关联设备的设备信息的前提下，通过设备信息可以验证设备信息对应的设备是否为投屏关联设备。
示例性的，当投屏关联设备中的任一电子设备在连接到局域网的情况下，可以向当前局域网内的设备发送搜索请求，示例性的，该搜索请求可以是以广播的形式发送，该搜索请求中可以包括当前设备本身的设备信息/地址信息，便于接收到搜索请求的设备进行信息反馈。当前局域网内设备响应搜索请求并向投屏发送端反馈设备信息；发送所述请求的设备可以对接收的设备信息进行验证，例如将接收的设备信息与第一投屏方式中接入的设备的设备信息进行比较，若接收的设备信息与第一投屏方式中接入的设备的设备信息相同，则当前局域网内接收到搜索请求的设备为投屏关联设备，若接收的设备信息与第一投屏方式中接入的设备的设备信息不同，则当前局域网内接收到搜索请求的设备不为投屏关联设备。
在一些实施方式中，设备信息包括设备标识和投屏会议标识；基于接收的设备信息验证当前局域网内的设备是否为投屏关联设备，包括：将设备信息中的投屏会议标识与当前设备的投屏会议标识进行比对，以及，将设备信息中的设备标识与第一投屏方式中投屏关联设备的设备标识进行匹配；若设备信息中的投屏会议标识与当前设备的投屏会议标识相同，且设备信息中的设备标识与第一投屏方式中投屏关联设备的设备标识匹配成功，则确定当前局域网内的设备为投屏关联设备。
其中，设备标识是指可用于识别设备的标识信息，具有唯一性，设备标识可以包括但不限于IP、端口等信息。投屏会议标识是指可用于云投屏的投屏会议标识信息，例如，投屏会议标识可以为ROOM ID，ROOM ID可为二维码、文本或者字符串等形式，在此不做限定。需要说明的是，通过投屏会议标识可以加入投屏(会议)房间，该投屏会议标识为在投屏的起始时刻预先存储得到，其中接入同一投屏过程的投屏关联设备中存储的投屏会议标识相同，该投屏会议标识可以是由投屏关联设备中的任一设备请求的，通过展示的方式或者数据传输的方式，实现投屏关联设备对投屏会议标识的存储。需要说明的是，本实施例通过设备标识和投屏会议标识对当前局域网内的设备进行验证，提升了投屏关联设备验证的可靠性。
示例性的，在投屏发送端接收的IP、端口完全与之前通过第一投屏方式连接的投屏接收端的IP、端口相同，且接收的ROOM ID与之前通过第一投屏方式所使用的ROOM ID相同的情况下，可以将当前局域网内的设备确定为投屏关联设备。
在一些实施方式中，在同一局域网内搜索到全部的投屏关联设备的情况下，还包括：对投屏关联设备进行局域网连接；在任一投屏关联设备连接失败的情况下，确定当前网络环境不满足局域网投屏方式的投屏切换条件。
可以理解的是，在确定投屏关联设备之后，可以对投屏关联设备进行局域网连接，由于设备移动、局域网信号波动等因素影响，可能导致投屏关联设备无法连入局域网，可以将当前网络环境确定为不满足局域网投屏方式的投屏切换条件，不进行投屏方式的切换，从而避免投屏质量下降的情况发生。通过对投屏关联设备进行局域网连接，保证了投屏方式顺畅地切换为局域网投屏方式，可在局域网投屏方式进行正常投屏。
在一些实施方式中，第一投屏方式为云投屏方式；确定当前网络环境对应的第二投屏方式，包括：离开云投屏的投屏房间，并向投屏关联设备发送局域网投屏指令，以使投屏关联设备接收局域网投屏指令，并离开云投屏的投屏房间。
在本实施中，云投屏方式是指通过广域网或者互联网进行投屏显示的投屏方式。与局域网相比，广域网或者互联网具有更广的通信范围，可以使投屏方法的应用场景下更加丰富。云投屏方式可以通过任意网络实现投屏，但云投屏方式延迟较高且会产生上下行流量费用。可以理解的是，在投屏发送端与投屏接收端无法接入同一局域网，或者投屏发送端和投屏接收端其中一端的局域网信号差的情况下，云投屏方式可以作为备选投屏方式，保证投屏质量。
示例性的，图4是本公开实施例所提供的一种云投屏方法的示意图。云投屏方法步骤包括：0.投屏接收端启动云投屏；1.投屏接收端向云会议服务器申请投屏会议标识(ROOM ID)，投屏会议标识可以为PIN码或者二维码；2.云会议服务器向投屏接收端返回投屏会议标识；3.投屏接收端根据投屏会议标识加入投屏房间；4.投屏接收端展示投屏会议标识；5.投屏发送端开始云投屏；6.投屏发送端通过扫描或者输入投屏会议标识加入投屏房间；7.云会议服务器将加入成功结果返回至投屏发送端；8.投屏发送端抓屏录音编码生成音视频流；9.投屏发送端将音视频流发送至云会议服务器；10.云会议服务器将音视频流传输至投屏接收端；11.投屏接收端对音视频流进行解码并展示。
图5是本公开实施例所提供的一种投屏切换方法的示意图。图5中由云投屏方式切换为局域网投屏方式，在云投屏方式的投屏过程中，投屏切换方法的步骤包括：0.投屏发送端检测到可以进行局域网连接；1.投屏发送端启动局域网业务搜索，发送搜索请求；2.投屏接收端响应搜索请求，并返回投屏接收端的IP、端口和投屏会议标识等信息；3.投屏发送端向投屏接收端发起局域网连接；4.投屏发送端检测局域网连接结果，并离开云投屏房间；5.投屏发送端向投屏接收端发送局域网投屏指令；6.投屏接收端离开云投屏房间，接收局域网投屏指令；7.投屏发送端抓屏录音编码生成音视频流；8.投屏发送端将音视频流发送至投屏接收端；9.投屏接收端对音视频流进行解码并展示。
本公开实施例的技术方案，若投屏发送端与投屏接收端位于同一局域网内，则将投屏方式切换为局域网投屏方式，并根据局域网投屏方式进行投屏，提高了投屏质量。
图6为本公开实施例提供的一种投屏方法的流程示意图，本实施例的方法与上述实施例中提供的投屏方法中多个示例方案可以结合。本实施例提供的投屏方法进行了细化。例如，所述第一投屏方式为局域网投屏方式，所述第二投屏方式为云投屏方式；所述云投屏方式的投屏切换条件为：投屏关联设备的局域网断连，且支持互联网接入。
如图6所示，该方法包括：
S310、在采用局域网投屏方式的投屏过程中，检测投屏关联设备的当前网络环境。
S320、若投屏关联设备的局域网断连，且支持互联网接入，则将投屏方式切换为云投屏方式。
S330、采用所述云投屏方式进行投屏。
在本实施例中，局域网断连是指投屏关联设备断开与局域网的连接。可以理解的是，在投屏关联设备的局域网断连，且支持互联网接入的情况下，将投屏方式切换为云投屏方式，可以避免投屏中断的情况发生，从而保证了投屏显示画面的连贯性。
在一些实施方式中，投屏关联设备预先存储有云投屏方式的投屏会议标识；确定当前网络环境对应的第二投屏方式，包括：基于投屏会议标识，加入云投屏方式的投屏会议房间。
可以理解的是，投屏关联设备预先存储云投屏方式的投屏会议标识，可以确保在局域网连接断开后，使投屏方式切换有据可依，并加入同一投屏会议房间，提升了投屏方式切换的速度和投屏连接的准确性。
在一些实施方式中，投屏会议标识的确定方式包括：接入投屏的任一设备，向云会议服务器发送会议申请，并接收云会议服务器反馈的投屏会议标识；接入投屏的任一设备展示投屏会议标识或者将投屏会议标识发送至接入投屏的其他设备。
示例性的，在投屏关联设备通过局域网投屏方式进行投屏的情况下，投屏关联设备中的任一设备可以向云会议服务器发送会议申请，云会议服务器向投屏关联设备内多个设备反馈投屏会议标识，投屏关联设备内多个设备将投屏会议标识存储在设备本地，以便在局域网断连时，根据投屏会议标识加入投屏会议房间，实现了投屏的无缝切换，保证了投屏显示画面的连贯性，并且该过程无需用户参与，提升了用户体验。
示例性的，图7是本公开实施例所提供的一种投屏切换方法的示意图。投屏切换方法的步骤包括：1.投屏发送端启动局域网业务搜索；2.投屏接收端响应搜索请求，并返回IP、端口和投屏会议标识等信息；3.投屏发送端向投屏接收端发起局域网连接，投屏接收端返回加入结果；4.投屏发送端向投屏接收端发送局域网投屏指令，投屏接收端返回加入结果；5.投屏发送端抓屏录音编码生成音视频流；8.投屏发送端将音视频流发送至投屏接收端；6.投屏接收端对音视频流进行解码并展示。例如，A0.在投屏发送端检测到局域网断连事件情况下；A1.投屏发送端检测并断开局域网投屏，获取投屏会议标识；A2.投屏发送端根据投屏会议标识加入投屏会议房间，云会议服务器向投屏发送端返回加入结果；B0.投屏接收端检测到局域网断连事件；B1：投屏接收端检测并断开局域网投屏，获取投屏会议标识；B2：投屏接收端根据投屏会议标识加入投屏会议房间，云会议服务器向投屏接收端返回加入结果；A3.投屏发送端抓屏录音编码生成音视频流；A4.投屏发送端将音视频流发送至云会议服务器；A5.云会议服务器将音视频流传输至投屏接收端；A6.投屏接收端对音视频流进行解码并展示。
