图1为本公开实施例中的一种视频投屏方法的流程图，本实施例可适用于客户端中进行视频投屏的情况，该方法可以由视频投屏装置执行，该装置可以采用软件和/或硬件的方式实现，当该装置为采用软件的方式实现时，该装置可配置于电子设备中，例如移动终端，具体包括手机、电脑或平板电脑等；该装置采用硬件的方式实现时，该装置可以是上述电子设备。为了便于理解，下面以该装置为第一设备为例，进行介绍。
如图1所示，该方法可以应用于第一设备，该方法包括如下步骤：
S101、接收投屏开启指令。
如图2所示，第一设备21可配置有视频投屏装置。具体的，第一设备21可以通过该视频投屏装置将第一设备21上播放的视频投屏到第二设备22上进行播放。其中，第一设备21具体可以是手机，第二设备22具体可以是电视。在其他实施例中，第一设备21不限于是手机，例如，第一设备还可以是除手机之外的终端设备，同理，第二设备22也不限于是电视，例如，第二设备还可以是其他具有视频播放功能的设备。在一些实施例中，第一设备21可以称为投屏设备。第二设备22可以称为被投屏设备，例如手机可以称为投屏设备，电视可以称为被投屏设备。
具体的，如图3所示为第一设备21的用户界面，该用户界面可以是第一设备21中安装的视频应用程序提供的用户界面。该视频应用程序具体可以是播放视频的应用程序。可以理解的是，此处只是示意性说明，并不对用户界面上显示的内容或用户界面中显示内容的布局进行限定。如图3所示，该用户界面上可以显示有多个视频的缩略图。例如，30表示多个缩略图中的任意一个。第一设备21的视频应用程序中的播放器可记为第一播放器。当用户在第一设备21的用户界面上对缩略图30进行操作后，第一设备21可以在该用户界面中的第一播放器31中播放缩略图30对应的视频。第一播放器31具体可以是视频播放器。此处，可以将第一播放器31当前播放的视频记为第一视频。具体的，用户对缩略图30的操作不限于点击、长按、双击等操作，还可以是其他操作。
另外，用户对用户界面的操作还可以触发投屏开启指令，从而使得第一设备21可以接收到用户触发的投屏开启指令。例如，第一设备21的用户界面还显示有投屏按钮32。例如，在第一播放器31播放第一视频的同时，投屏按钮32的周围可以提示“试试投屏到电视上看吧”。若用户希望将第一视频投屏到电视上，则可以对投屏按钮32进行操作，进而触发投屏开启指令。此处并不限定投屏按钮32在用户界面中的位置。例如，投屏按钮32可以显示在第一播放器31的右上角，投屏按钮32还可以显示在用户界面的其他位置。此外，投屏按钮32在用户界面中的位置可以是固定的或者非固定的。当投屏按钮32在用户界面中的位置是非固定的时，用户可以拖拽该投屏按钮32到用户界面的某一位置。
具体的，用户可通过对投屏按钮32的操作，开启第一设备21或视频应用程序的投屏功能。为了便于描述，下文以开启第一设备21的投屏功能为例进行介绍。例如，当用户对 投屏按钮32进行操作时，用户可以触发一个投屏开启指令，当第一设备21接收到该投屏开启指令时，第一设备21可以根据该投屏开启指令开启第一设备21的投屏功能。具体的，用户对投屏按钮32的操作不限于点击、长按、双击等操作，还可以是其他操作。
S102、响应于所述投屏开启指令，将第一视频投屏到目标设备。
其中，目标设备可以为第二设备，后续若无特殊说明，目标设备和第二设备均指代被投屏设备。在一些可能的实现方式中，当第一设备21接收到用户的投屏开启指令时，第一设备21可以显示投屏引导页。由于第一设备将视频进行投屏需要消耗一定的流量，该投屏引导页可以提示用户将第一设备21与周围的无线保真(Wireless-Fidelity，Wi-Fi)热点进行连接。具体的，该投屏引导页可以显示第一设备21周围的Wi-Fi热点的名称，第一设备21可以根据用户对某个Wi-Fi热点名称的点击操作，连接该Wi-Fi热点。进一步的，第一设备21可以搜索周围的可投屏设备，例如可投屏电视。在第一设备21搜索可投屏设备的过程中，该投屏引导页可以提示“正在搜索可投屏设备”。当第一设备21与可投屏设备之间的网络连接信号较弱时，该投屏引导页可以提示“请检测网络连接”。当第一设备21周围的可投屏设备没有连接到Wi-Fi热点时，该投屏引导页可以提示“请保持手机和电视处于同一Wi-Fi热点的覆盖下”。
需要说明的是，第一设备21与可投屏设备之间的连接方式不限于Wi-Fi，还可以是其他的无线连接方式，例如蓝牙。在另一些实施例中，连接方式还可以是有线连接方式。在第一设备21与可投屏设备建立连接后，该可投屏设备可称为被投屏设备，即上文所述的第二设备22。
具体的，当第一设备21检测到周围的可投屏设备时，投屏引导页可以显示可投屏设备的标识。当可投屏设备为多个时，本实施例并不限定多个可投屏设备的标识在投屏引导页中的排列顺序。例如，排列在第一位的可投屏设备的标识可以是最近一次与第一设备21连接的可投屏设备的标识。
进一步，第一设备21可以自动与最近一次连接的可投屏设备再次连接。在另一些实施例中，第一设备21可以根据用户对多个可投屏设备的标识中某一可投屏设备的标识的选择操作，与被用户选中的可投屏设备建立连接。
可选的，第一设备21可以向第二设备发送第一投屏指令，该第一投屏指令包括第一视频的视频信息，第一投屏指令用于控制第二设备22根据第一视频的视频信息，播放第一视频。
当第一设备21与第二设备22建立连接后，第一设备21可以向第二设备22发送第一投屏指令，该第一投屏指令包括第一视频的视频信息。可选的，第一视频的视频信息包括如下至少一种：第一视频的视频数据和第一视频的视频地址。
在一种可能的实现方式中，第二设备22在接收到第一投屏指令后，可直接根据第一视频的视频信息，播放该第一视频。例如，第二设备22可以投屏显示第一视频。
在另一种可能的实现方式中，第一投屏指令用于控制第二设备22中的第二播放器开启。例如，第二设备22在接收到第一投屏指令后，第二设备22可根据该第一投屏指令启动第二设备22中的播放器，第二设备22中的播放器可记为第二播放器。第二设备22可以根据 第一视频的视频信息，控制第二设备22中的第二播放器，播放该第一视频。第二播放器可以记录或缓存第二设备22播放过的视频的视频信息。例如，第一视频的视频数据或第一视频的视频地址。当用户需要在第二设备22上观看第一视频时，用户可以在第二播放器中寻找第一视频的视频信息，使得第二播放器直接播放第一视频，从而用户无需再次利用第一设备21对第二设备22播放过的视频再次进行投屏操作，进一步提高了投屏效率。
在一些实施例中，第一设备21向第二设备22发送第一投屏指令之后，第一设备21还可以向第二设备22发送至少一次投屏指令。例如，第一设备21向第二设备22发送第一投屏指令之后，第一设备21还可以向第二设备22发送第二投屏指令、第三投屏指令等。其中，第二投屏指令用于控制第二设备中的第二播放器开启。第三投屏指令也可以用于控制第二设备22中的第二播放器开启。以第二投屏指令为例，第二投屏指令不仅可以用于控制第二设备22投屏播放不同于第一视频的其他视频，也可以控制第二设备22的第二播放器开启，从而使得第二设备22控制第二播放器播放第二视频等。
第一设备21将第一播放器31中当前播放的第一视频投屏到第二设备22进行播放可以有如下几种实现方式：
在第一种实现方式中，第一设备21将第一播放器31中当前播放的第一视频的视频数据通过第一设备21和第二设备22之间的无线传输通道发送给第二设备22，视频数据可以是视频中的每一帧图像数据和每一帧音频数据。第二设备22在接收到第一视频的视频数据播放该第一视频。在第一种实现方式中，第一设备21和第二设备22可以同步播放该第一视频，也就是说，第一设备21上第一视频的播放进度与第二设备22上第一视频的播放进度同步。
第二种实现方式中如图4所示，第一设备21可以从视频应用程序对应的服务器23获取第一播放器31中当前播放的第一视频的视频地址，该视频地址可以是统一资源定位符(Uniform Resource Locator，URL)。第一设备21将该第一视频的视频地址发送给第二设备22。第二设备22根据该第一视频的视频地址获取该第一视频的视频数据后，播放该第一视频。在一些示例中，第一视频存储在服务器24中，第二设备22可以根据该第一视频的视频地址从服务器24获取到第一视频的视频数据。
需要说明的是，服务器23和服务器24可以是同一个服务器，也可以是不同的服务器。在第二种实现方式中，当第一设备21将第一视频的视频地址发送给第二设备22之后，第一设备21可以暂停播放第一视频，从而降低第一视频的耗电；当然在第二种情况中，第一设备21也可以不暂停播放第一视频。
可选的，第一视频的视频信息还可以包括第一视频的投屏参数。该投屏参数包括如下至少一种：播放进度、分辨率和播放音量。
在一些实施例中，第一设备21向第二设备22发送的第一视频的视频信息中包括第一视频在第一设备21中的播放进度。当第一视频在第一设备21上播放到30％时，用户开启投屏功能，第一设备21可以将第一视频的播放到30％的播放进度发送给第二设备22，从而使得第二设备22可以从播放到30％的播放进度继续播放第一视频。当然，第二设备22还可以根据第一视频的分辨率、播放音量等投屏参数，播放第一视频。
S103、获取所述第一视频在所述目标设备上的播放进度。
其中，第一视频在目标设备上的播放进度可以是第二设备上第一视频的播放进度。在一些实施例方式中，第一设备21将第一播放器31中当前播放的第一视频投屏到第二设备22进行播放后，第一设备21可以实时监测第一视频的播放进度，第一设备21也可以非实时监测第一视频的播放进度。
在一些示例中，第一设备21将第一视频的视频数据发送给第二设备22的情况下，第一设备21和第二设备22同步播放该第一视频，第一设备上第一视频的播放进度与第二设备上第一视频的播放进度同步，第一设备21可以实时监测第一设备21上第一视频的播放进度。
在另一些示例中，第一设备21将第一视频的视频地址发送给第二设备22，第二设备22可以根据该第一视频的视频地址，从服务器24获取与该第一视频的视频地址对应视频数据，并进行播放。由于第一设备21和第二设备22获取第一视频的视频数据的来源等信息可能不同，第一设备21上第一视频的播放进度并不影响第二设备22上第一视频的播放进度。因此，第二设备22播放第一视频之后，第一设备21可以暂停播放第一视频。此时，第一设备21可以实时监测第二设备22上第一视频的播放进度。例如，第二设备22可以将第二设备22上第一视频的播放进度实时发送给第一设备21，或者第二设备22在即将播放完第一视频时，将第二设备22上第一视频的播放进度发给第一设备21，以便第一设备21将第二投屏指令发给第二设备22，以将第二视频投屏到第二设备22。
S104、根据所述播放进度，确定所述第一视频投屏完成时，将第二视频投屏到所述目标设备。
在一些实施例中，第一设备21根据第二设备上第一视频的播放进度，确定第一视频在第二设备22上投屏完成时，第一设备21可以自动将第二视频投屏到第二设备22上，从而无需用户进一步的手动投屏操作，也可以使得第二设备22上播放的投屏视频是连续的。
可选的，第一设备21根据所述第二设备上第一视频的播放进度，确定所述第一视频投屏完成时，向第二设备22发送第二投屏指令，第二投屏指令包括第二视频的视频信息，第二投屏指令用于控制第二设备22根据第二视频的视频信息，播放第二视频。
在一些示例中，第一设备21确定第二设备22上第一视频投屏完成时，第一设备21向第二设备22发送第二投屏指令，该第二投屏指令包括第二视频的视频信息，第二视频的视频信息包括第二视频的视频数据或视频地址。同理，第二设备22可以根据第二视频的视频数据与第一设备21同步播放该第二视频；第二设备22也可以根据的第二视频的视频地址，从服务器24获取该第二视频的视频数据，播放该第二视频。
在一种可能的实现方式中，第二设备22在接收到第二投屏指令后，可直接根据第二视频的视频信息，播放该第二视频。例如，第二设备22可以投屏显示第二视频。
在另一种可能的实现方式中，所述第二投屏指令用于控制第二设备中的第二播放器开启。例如，第二设备22在接收到第二投屏指令后，第二设备22可根据该第二投屏指令启动第二设备22中的播放器，第二设备22中的播放器可记为第二播放器。第二设备22可以根据第二视频的视频信息，控制第二设备22中的第二播放器，播放该第二视频。同理，第 二播放器可以记录或缓存第二设备22播放过的视频的视频信息。例如，第二视频的视频数据或第二视频的视频地址。当用户需要在第二设备22上观看第二视频时，用户可以在第二播放器中寻找第二视频的视频信息，使得第二播放器直接播放第二视频，从而用户无需再次利用第一设备21对第二设备22播放过的视频再次进行投屏操作，进一步提高了投屏效率。
可选的，第一设备21可以获取第二视频的视频信息，根据所述第二设备上第一视频的播放进度，确定所述第一视频投屏完成时，根据所述第二视频的视频信息，向第二设备22发送第二投屏指令。
在一些实施例中，第一设备21可以预先获取第二视频的视频信息。当第一设备21确定第一视频在第二设备22上投屏完成时，根据预先获取的第二视频的视频信息，向第二设备22发送第二投屏指令。
其中，第一设备21获取第二视频的视频信息，可包括如下几种实现方式：
第一种实现方式中，第一设备21从视频信息列表中获取第二视频的视频信息，视频信息列表包括一个或多个视频的视频信息，在一些示例中，视频信息列表中的视频可以是排在第一视频之后需要播放的视频，例如第二视频。
第一设备21或视频应用程序中可预先存储有视频信息列表。其中，第二视频的视频信息可以是该视频信息列表中的任意一个视频的视频信息。例如，第二视频的视频信息是该视频信息列表中的第一个视频信息，该视频信息列表中视频的视频信息可以是在第一设备21播放第一视频之前存储在第一设备21或第一设备21的视频应用程序中，当然，视频信息列表中视频的视频信息也可以是第一设备21播放第一视频时或播放第一视频后存储。此外，第一视频也可以是该视频信息列表中的视频。
第二种实现方式中，第一设备21从服务器获取第二视频的视频信息。在一些示例中，当视频信息列表为空时，第一设备21可以向服务器23发送获取请求，以获取一个或多个视频的视频信息。其中，第二视频的视频信息可以是该一个或多个视频的视频信息中的任意一个，也可以是播放列表中预设位置上视频的视频信息，例如预设位置可以是播放列表中排在第一视频之后的位置。
在一些实施例中，第一设备21可以在第一视频的播放进度大于或等于预设进度时，获取第二视频的视频信息。第一设备21可以在第一视频播放完成之前获取第二视频的视频信息。例如，第一设备21可以在第一视频的播放进度达到70％-90％的时，获取第二视频的视频信息。第一设备21也可以在第一视频播放完成时获取第二视频的视频信息。例如，第一设备21可以在第一视频的播放进度达到100％的时，获取第二视频的视频信息。
在本实施例中，第一设备21根据第一视频在第二设备22上的播放进度，确定第一视频在第二设备22上投屏完成的方法，可包括如下几种实现方式：
第一种可能的情况中，第一视频投屏完成具体可以是第一视频在第二设备22上播放完成，例如第一视频在第二设备22上的播放进度达到了100％。在第一设备21上第一视频的播放进度与第二设备22上第一视频的播放进度同步时，第一视频投屏完成也可以是第一视频在第一设备21上播放完成。
第二种可能的情况中，第二设备22上播放的投屏视频(例如第一视频)包括按顺序播放的片头部分、剧情部分和片尾部分，预设进度可以是投屏视频播放完成剧情部分时对应的播放进度，也可以是投屏视频播放完成片尾部分时对应的播放进度。
在一些示例中，第一视频在第二设备上的播放进度达到预设进度，具体可以是第一视频的剧情部分(主体内容)在第二设备22上播放完成该第一视频的播放进度。例如，第一视频是一集电视剧，这一集电视剧包括片头部分、剧情部分和片尾部分。其中，片头部分、剧情部分和片尾部分中各个部分在每一集电视剧中所占的比例信息具体可以是各个部分在每一集电视剧中持续的时长与每一集电视剧的总时长的比值。这一集电视剧的总时长例如是40分钟，片头部分占2分钟，剧情部分占36分钟，片尾部分占2分钟。这一集电视剧投屏完成具体可以是这一集电视剧的剧情部分在第二设备22上播放完成。也就是说，如果将40分钟作为100％的进度，那么当片头部分播放完成时，这一集电视剧的播放进度达到了5％。当剧情部分播放完成时，这一集电视剧的播放进度达到了95％。当片尾部分播放完成时，这一集电视剧的播放进度达到了100％。如此，预设进度可以是95％，也可以是100％。
第一视频对应的电视剧可来源于服务器23，服务器23可以统计电视剧中每一集电视剧的片头部分、剧情部分和片尾部分中各个部分在每一集电视剧中所占的比例。服务器23可以将每一集电视剧的片头部分、剧情部分和片尾部分中各个部分在每一集电视剧中所占的比例信息、时间戳信息等发送给第一设备21。第二设备22播放第一视频的过程中，第一设备21确定第一视频的播放进度达到预设进度95％，且第一设备21确定第一视频的片头部分和剧情部分在该第一视频中所占的比例为95％时，第一设备21可以确定第一视频的主体内容即剧情部分在第二设备22上播放完成，此时可以确定第一视频投屏完成。接着第一设备21可根据第二视频的视频信息，将第二视频投屏到第二设备22进行播放。从而可以在视频投屏时自动跳过片尾部分。
本公开实施例提供的视频投屏方法，第一设备21根据用户的投屏开启指令，将当前播放的第一视频投屏到第二设备，并在第一视频投屏到第二设备之后，监测第一视频的播放进度，当根据第一视频的播放进度，确定第一视频投屏完成时，第一设备可以自动将第二视频投屏到第二设备，从而使得前一个视频投屏完成后可以继续投屏下一个视频，用户无需在前一个视频投屏完成后进行投屏操作。也就是说，多个视频可以在第二设备上连续投屏播放，中间不需要用户频繁地进行投屏操作，通过在前一视频投屏完成时自动投屏下一个视频，使得第二设备可以自动连续投屏，提高了投屏效率，从而提高了用户体验。
如图5所示为本实施例提供的视频投屏方法的示意图。该方法包括如下几个步骤：
S501、视频进入投屏状态。
用户点击投屏按钮32后投屏功能开启，第一设备21或第一设备21上安装的视频应用程序进入投屏状态。以第一设备21为例，当第一设备21视频投屏到第二设备22进行播放时，第一设备21进入投屏状态。该投屏状态可以被保存在第一设备21中。
在第一设备21处于开机状态或在该视频应用程序存活的生命周期中，该第一设备21或视频应用程序可以记忆该投屏状态，该投屏状态可以是第一设备21或视频应用程序当前是正在投屏的状态。其中，该视频应用程序存活的生命周期具体可以是该视频应用程序的 运行期间，该运行期间可以包括在前端的运行期间，也可以包括在后台的运行期间。
S502、判断视频信息列表是否为空，若是，则执行S503，否则执行S504。
第一设备21或视频应用程序中可以预先存储有视频信息列表，该视频信息列表可包括一个或多个视频的视频信息。当第一设备21或视频应用程序进入投屏状态时，第一设备21可以检测该视频信息列表是否为空。
S503、获取一个或多个视频的视频信息，并将一个或多个视频的视频信息存储到视频信息列表。
在一些示例中，当第一设备21检测到该视频信息列表为空时，第一设备21可以从服务器23获取一个或多个视频的视频信息，并将该一个或多个视频的视频信息存储到视频信息列表中。
在另一些示例中，当第一设备21检测到该视频信息列表为空时，第一设备21可以根据第一视频的视频信息向服务器23发送获取请求，以获取与第一视频相关的第二视频的视频信息。第一设备21可以将该第二视频的视频信息存储到视频信息列表中，同理，第一设备21还可以从服务器23获取更多视频的视频信息存储到视频信息列表中。
S504、等待视频投屏完成。
当第一设备21检测到该视频信息列表不为空时，第一设备21等待第一视频投屏完成。
S505、从视频信息列表中获取新的视频信息，并根据新的视频信息，对新的视频进行投屏。
新的视频可以是第二视频，新的视频信息可以是第二视频的视频信息。当第一设备21确定第一视频投屏完成时，从视频信息列表中获取新的视频信息。当第一设备将第二视频投屏到第二设备后之后，又可以返回到执行S501。通过重复执行S501-S505可以实现视频不间断的投屏。
本公开实施例提供的视频投屏方法，第一设备21通过判断视频信息列表是否为空，若该视频信息列表为空，则获取一个或多个视频的视频信息，并将一个或多个视频的视频信息存储到该视频信息列表中，使得该视频信息列表中持续有可用的视频的视频信息，从而使得第一设备可以持续地将视频信息列表中视频，投屏到第二设备上。在第一视频的播放进度大于或等于预设进度时，第一设备21从视频信息列表中获取第二视频的视频信息。在第一视频还未投屏完成时，第一设备21从视频信息列表中提前获取第二视频的视频信息，可保证第一视频投屏完成时，紧接着将第二视频投屏到第二设备22上，从而使得第二设备及时地播放第二视频。
图6为本公开实施例中的另一种视频投屏方法的流程图。本实施例在上述实施例的基础上，进一步对视频投屏方法进行了具体说明。相应的，如图6所示，本实施例的方法应用于如上所述的第一设备21中，具体包括：
S601、接收投屏开启指令。
S601和S101的实现过程和具体原理类似，此处不再赘述。
S602、响应于所述投屏开启指令，将第一视频投屏到目标设备。
S602和S102的实现过程和具体原理类似，此处不再赘述。
S603、控制投屏设备的投屏应用程序中的第一播放器进入暂停状态。
其中，投屏设备可以是第一设备21。第一设备21中的视频应用程序具备投屏功能时，该视频应用程序还可称为投屏应用程序。在一些实施例中，第一设备21将第一播放器31中当前播放的第一视频的视频地址发送给第二设备22，第二设备22可以根据第一视频的视频地址，从服务器24中获取第一视频的视频数据，并播放第一视频。在一些可能的实现方式中，第一设备21的第一播放器31中播放第一视频的播放进度并不影响第二设备22的第二播放器的播放进度，即第二设备22播放第一视频并不受限于第一设备21中播放第一视频。因此，第一设备21将第一视频投屏到第二设备22后，第一设备21可以控制第一播放器31进入暂停状态，使第一播放器31暂停播放第一视频。由第二设备22播放第一视频，从而可以节省第一设备21的网络流量、降低第一设备21的耗电等。
在另一种可能的实现方式中，第一设备21将第一播放器31中当前播放的第一视频投屏到第二设备22后，第一设备21也可以控制第一播放器31继续播放第一视频，即第一设备21和第二设备22可以同步播放第一视频。
当第一播放器31暂停播放时，第一设备21进入投屏控制页面，该投屏控制页面具体可以是如图7所示的用户界面。如图7所示，第一播放器31暂停播放，第一播放器31上显示暂停标识33。
S604、从所述目标设备接收所述第一视频的播放进度。
第一设备21可以从第二设备22实时接收第一视频的播放进度，第一设备21可以在该投屏控制页面中实时更新第一视频的播放进度。如图7所示，进度条34表示第一视频的播放进度。可以理解的是，第二设备22上也可以显示第一视频的播放进度。也就是说，第一视频的播放进度可以在第一设备21和第二设备22上同步更新。
另外，用户可以通过拖动进度条34控制第二设备22上第一视频快进或快退，从而调节第二设备22上第一视频的播放进度。用户还可以通过长按快进键35控制第二设备22上第一视频快进，长按快退键36控制第二设备22上第一视频快退。
在一些示例中，当用户对该投屏控制页面中的进度控制图标例如进度条34进行操作时，可以触发相应的进度控制指令。第一设备21将该进度控制指令发送给第二设备22。当第二设备22接收到该进度控制指令时，根据该进度控制指令控制第一视频的播放进度。
需要说明的是，在该投屏控制页面中用于控制播放进度的图标并不限于如图7所示的进度条34、快进键35和快退键36，还可以包括其他图标。
用户可以通过第二设备22的控制器控制第一视频的播放进度。例如，当第二设备22为电视时，该控制器具体可以是遥控器。用户可以通过遥控器控制电视上第一视频的播放进度。
用户还可以在该投屏控制页面控制第一视频的播放音量。如图7所示，当用户对音量控制图标37进行操作时，可以触发音量控制指令。第一设备21将该音量控制指令发送给第二设备22，从而使得第二设备22可以调节第一视频的播放音量。用户也可以通过第二设备22的控制器控制第一视频的播放音量。
需要说明的是，在该投屏控制页面中用于控制播放音量的图标并不限于如图7所示的音量控制图标37，还可以包括其他图标。例如，该投屏控制页面可以显示有“+”和“—”。当用户长按“+”或“—”时，可以触发播放音量调节指令。当第一设备21接收到该播放音量调节指令时，根据该播放音量调节指令调节第一视频在第二设备22中的播放音量。其中，“+”用于增大播放音量，“—”用于降低播放音量。此外，如果第一设备21为手机时，用户也可以通过按该手机的音量调节按钮时，可以触发播放音量调节指令，以用于调节第一视频在第二设备22中的播放音量。
需要说明的是，用户也可以通过第二设备22的控制器控制第一视频暂停。例如，第二设备22为电视，第二设备22的控制器为遥控器，该遥控器包括暂停按钮，当用户按压暂停按钮时可触发视频暂停控制指令。接着遥控器将该视频暂停控制指令发送给第二设备22，第二设备22根据该视频暂停控制指令控制第一视频暂停。
用户还可以通过该投屏控制页面中的分辨率控制图标38调节第二设备22上第一视频的清晰度。例如，当用户对分辨率控制图标38进行操作时，该投屏控制页面中可弹出分辨率选择弹窗，该分辨率选择弹窗可包括多种分辨率模式，用户可以选择其中一种分辨率模式。具体的，当用户选择某一种分辨率模式时可触发分辨率配置指令，第一设备21将该分辨率配置指令发送给第二设备22，第二设备22可根据该分辨率配置指令所指示的分辨率模式，配置第一视频在第二设备22上显示的分辨率，从而实现对第二设备22上第一视频的清晰度进行调节。
在一些实施例中，视频应用程序还具有更换可投屏设备的功能。例如，当用户需要将第二设备22更换为其他设备时，可以点击设备更换图标39，此时第一设备21可进入设备搜索页面，该设备搜索页面具体可以是如上所述的投屏引导页，该投屏引导页包括多个可投屏设备的标识。用户可以选择除第二设备22之外的其他可投屏设备作为新的第二设备。当用户单击关闭设备搜索页面后，第一设备21可回到如图7所示的投屏控制页面。
需要说明的是，如图7所示的用户界面只是示意性说明，本实施例并不限定各个图标的形状、位置等。
S605、当所述第一视频的播放进度大于或等于预设进度时，获取第二视频的视频信息。
当第一视频的播放进度大于或等于预设进度时，第一设备21可以获取第二视频的视频信息。例如第二视频的视频信息可以是第二视频的视频地址(例如URL)，也可以是第二视频的视频数据。
S606、在所述第一视频投屏完成时，将所述第二视频的视频信息发送给所述目标设备，所述目标设备用于根据所述第二视频的视频信息获取所述第二视频，并播放所述第二视频。
以第二视频的视频信息为第二视频的视频地址为例，第一视频投屏完成时，第一设备21将第二视频的视频地址发送给第二设备22。第二设备22可以根据第二视频的视频地址从服务器24中获取该第二视频的视频数据，并播放该第二视频。
在一些实施例中，第二视频的视频信息还包括：第二视频的播放进度、第二视频的分辨率和第二视频的播放音量中的至少一种。
服务器23可以统计电视剧中每一集电视剧的片头部分、剧情部分和片尾部分中各个部 分在每一集电视剧中所占的比例。服务器23可以将每一集电视剧的片头部分、剧情部分和片尾部分中各个部分在每一集电视剧中所占的比例信息、时间戳信息等发送给第一设备21。
如上述实施例所述，当第二设备22上第一视频的播放进度达到95％时，第一设备可以确定第一视频投屏完成。第一设备21向第二设备22发送第二视频的视频信息，第二视频的视频信息不仅包括第二视频的视频地址，还可以包括第二视频的播放进度。例如，第二视频的播放进度可以是第二视频的起始播放进度。其中，起始播放进度可以是投屏视频播放完成片头部分时对应的播放进度。以投屏视频为第二视频为例，第二视频的起始播放进度可以是第二视频中的片头部分在该第二视频中所占的比例。例如，第二视频的起始播放进度可以是5％。也就是说，第二设备22可以从第二视频5％的播放进度开始播放第二视频。如此，当第二设备22从第二视频的5％开始播放时，可以跳过第二视频的片头部分，如此用户无需对电视剧中每一集电视剧的重复部分进行多次观看，提升用户体验。
第一设备21向第二设备22发送的第二视频的视频信息还可以包括第二视频的分辨率，从而使得第二设备22可以根据该第二视频的分辨率调节第二设备22上第二视频的分辨率。
可选的，第一设备21控制第一设备21的投屏应用程序中的第一播放器进入暂停状态之后，该方法还包括：第一设备21接收投屏停止指令，根据该投屏停止指令，控制投屏设备的投屏应用程序中的第一播放器进入播放状态。
当第一设备21或视频应用程序处于投屏状态时，用户还可以控制第一设备21或视频应用程序退出投屏状态。如图7所示，当用户再次对投屏按钮32进行操作时可触发一个投屏停止指令。也就是说，投屏按钮32可以是一个投屏控制开关，在非投屏状态下，用户点击一次投屏按钮32可控制第一设备21或视频应用程序进入投屏状态。在投屏状态下，用户点击一次投屏按钮32可控制第一设备21或视频应用程序退出投屏状态。
举例说明，在非投屏状态下，当用户点击一次投屏按钮32，第一设备21可以控制第一设备21或视频应用程序进入投屏状态。第一设备21上播放的视频可以投屏到第二设备22上播放。以第一设备21上播放的视频为第一视频为例，第一设备21上第一视频的播放进度为40％时，用户对投屏按钮32进行操作时，第一设备21控制第一设备21进入投屏状态。接着第一设备21向第二设备22发送第一视频的视频信息，该第一视频的视频信息可以包括第一视频的视频地址以及第一视频的播放进度(例如上述40％)，如此第二设备22可以根据第一视频的视频地址获取到第一视频的视频数据，并根据第一视频的播放进度，从40％处继续播放第一视频。如此，用户无需在第二设备22上，从该第一视频的0％处重新观看已观看过的重复部分，而是直接从未观看的部分开始观看，进而节约用户时间，提高用户体验。
接着，用户可触发投屏停止指令，例如当用户再次点击投屏按钮32时，可触发一个投屏停止指令，当第一设备21接收到该投屏停止指令时，第一设备21可控制第一设备21中的第一播放器进入播放状态。第二设备22上播放的投屏视频可以恢复到第一设备21上继续播放。在一些实施例中，第二设备22上播放第一视频时，第二设备22上第一视频的播放进度为50％，用户关闭了投屏功能，第一设备21从50％继续播放上述第一视频。当停止在第二设备22上投屏的时候，第一设备21上从第二设备22投屏结束时对应的播放进度， 继续播放第二设备上的投屏视频。如此用户无需在第一设备21上，从该第一视频的40％处重新观看第二设备已经播放过的重复部分，而是直接从未观看的部分开始观看，例如从第一视频的50％处开始观看，进而节约用户时间，提高用户体验。该方法可以实现第一设备21和第二设备22接力播放第一视频，从而保证了第一视频能够持续、不间断地播放，提高了用户观看视频的体验，提高了用户的满意度。在一些实现方式中，用户还可以在第二设备22的遥控器上点击返回按钮，从而控制第二设备22退出投屏状态，第二设备22上播放的第一视频可以恢复到第一设备21上继续播放，保证了第一视频能够持续、不间断地播放，提高了用户观看视频的体验。
本公开实施例提供的视频投屏方法，第一设备21通过第一设备21实时监测前一个视频在第二设备上播放的播放进度，当前一个视频的播放进度达到第二设备开始播放前一个视频的片尾部分对应的播放进度时，确定前一个视频在第二设备上投屏完成。第一设备21将下一个视频的视频信息发送给第二设备，使得第二设备开始播放下一个视频，如此第二设备可以跳过前一个视频的片尾部分，用户无需重复观看该片尾部分，节约用户时间，提高用户体验。
进一步，当前一个视频在第二设备22上播放完成时，第一设备21将下一个视频的播放进度和视频地址等视频信息发送给第二设备22，第二设备22无需从下一个视频的起始点(例如播放进度为0％)开始播放下一个视频，而是可以从下一个的视频的播放进度(例如5％)开始播放，如此第二设备22可以跳过下一个视频的片头部分。进而用户无需重复观看多个视频的重复部分，节约了用户时间，提高用户体验。
更进一步，第一设备21在非投屏状态下，第一设备21将当前第一设备21上播放的当前视频的播放进度和视频地址等视频信息发送给第二设备22，如此第二设备22可以根据该当前视频的播放进度和视频地址，直接从该当前视频的播放进度处播放该当前视频。用户无需在第二设备22上从头开始观看该当前视频。第一设备21在投屏状态下，第一设备21将第一设备21在当前视频未完全播放完时向第二设备发送的下一视频的投屏指令，第二设备22在未完全播放完当前视频时，即开始播放下一视频，如此第二设备22无需播放当前视频的片尾部分。并且，第一设备21通过将下一视频的起始播放进度发送给第二设备22，第二设备22无需播放下一视频的起始播放进度之前的内容如片头部分，从而节省用户时间，进而用户可以观看更多个视频，进一步提高了用户体验。
可选的，所述方法还包括：第一设备21确定第一视频投屏完成时，第一设备21的投屏应用程序的第一播放器关闭，第一设备21重新启动该第一播放器。
第一设备21将第一播放器31中当前播放的第一视频投屏到第二设备22播放，当第一视频投屏完成时，第一播放器31可能会被自动关闭。
在一些实施例中，当第一视频投屏完成时，第一设备21可以检测第一播放器31是否被关闭，若第一播放器31被关闭，可以重新启动第一播放器31，并且使第一播放器31处于暂停状态。
本公开实施例提供的视频投屏方法，第一设备21在检测到第一播放器被关闭后，通过 重新启动该第一播放器。如此保证第一设备21能够对后续视频正常投屏到第二设备22，减少投屏过程中，出现中断的情况，进一步减少用户再次进行手动投屏操作的次数，进一步提高用户使用第一设备将视频投屏到第二设备的便利性，提升用户体验。
与上述实施例相结合，当第一视频在第一设备21的视频应用程序的第一播放器31播放时，所述方法还可以包括如图8所示的如下几个步骤：

可选的，当所述投屏控制图标的显示条件成立时，第一设备21接收投屏控制图标显示指令。投屏控制图标94的显示条件可包括预设条件。作为一种示例，预设条件可以是第一设备21的投屏应用程序从前端运行状态转换为后台运行状态。如此，第一设备21检测到投屏应用程序从前端运行状态转换为后台运行状态时，即满足显示条件，第一设备21接收投屏控制图标显示指令。
图7所示的用户界面是视频应用程序提供的用户界面。在一些应用场景下，用户可能会控制该视频应用程序进入后台运行模式。在一些可能的实现方式中，当用户需要开启第一设备21上的其他应用程序时，可以通过点击如图7所示的返回按钮40，使第一设备21上的投屏应用程序从在前端运行状态转换为后台运行状态。例如第一设备21可以返回到桌面界面，该桌面界面可包括多个应用程序的图标，用户通过点击其他应用程序的图标可触发第一设备21启动其他应用程序，以便用户对其他应用程序进行使用。
在一些实施例中，用户通过对返回按钮40的操作可以触发一个后台运行指令。当第一设备21接收到该后台运行指令时，可以控制该视频应用程序到后台运行。
S802、响应于所述投屏控制图标显示指令，显示投屏控制图标，所述投屏控制图标用于投屏控制。
在一些实施例中，第一设备21检测到视频应用程序由前端运行状态转换到后台运行状态后，在第一设备21的桌面界面上显示一个投屏控制图标，该投屏控制图标用于进行投屏控制。在一些可能的实现方式中，用户可以通过该投屏控制图标切换投屏到第二设备的视频。例如，用户可以通过该投屏控制图像切换投屏到第二设备的视频为目标视频，该目标视频可以是用户选择的视频。在另一些可能的实现方式中，用户还可以通过该投屏控制图标控制第二设备22上播放的投屏视频的播放进度、播放音量、分辨率等。
如图9所示，91-93分别表示应用程序的图标，94表示投屏控制图标。该投屏控制图标94可以包括多个子图标，不同的子图标可以实现不同的控制功能。具体的，子图标95和子图标96可用于控制投屏视频的播放进度，所谓的投屏视频是指投屏到第二设备上播放的视频。例如，用户对子图标95或子图标96操作时可触发播放进度控制指令，第一设备21将该播放进度控制指令发送给第二设备22，第二设备22根据该播放进度控制指令，控制投屏视频在第二设备22上的播放进度。子图标97和子图标98可用于切换投屏视频。当 用户对子图标97或子图标98操作时可触发视频切换指令，第一设备21将该视频切换指令发送给第二设备22，该视频切换指令包括视频信息列表中目标视频的视频信息，例如目标视频的视频信息可以是下一个视频的视频信息，也可以是上一个视频的视频信息，或者是其他视频的视频信息。如此，第二设备22根据目标视频的视频信息，播放目标视频。
子图标99可用于调节投屏视频的分辨率。在一些可能的实现方式中，当用户对子图标99进行操作时，可以触发分辨率配置指令，第一设备21将该分辨率配置指令发送给第二设备22，如此第二设备22可以基于该分辨率配置指令控制第二设备上播放的投屏视频的分辨率。子图标100可用于控制投屏视频的播放音量。例如，当用户对子图标100进行操作时可触发播放音量控制指令，第一设备21将该播放音量控制指令发送给第二设备22，如此第二设备22可以根据该播放音量控制指令控制第二设备22上播放的投屏视频的播放音量。
子图标95用于控制第二设备22上播放的投屏视频快进。子图标96用于控制第二设备22上播放的投屏视频快退。子图标97用于将投屏到第二设备的视频切换为该视频的下一个视频。子图标98用于将投屏到第二设备的视频切换为该视频的上一个视频。子图标100可以是转动的，当子图标100逆时针转动时，控制第二设备22上播放的投屏视频的播放音量增大。当子图标100顺时针转动时，控制第二设备22上播放的投屏视频的播放音量减小。同理，当用户对子图标95或子图标96进行操作时可触发播放进度控制指令，第一设备21将该播放进度控制指令发送给第二设备22，如此第二设备22可以根据该播放进度控制指令，控制第二设备22上播放的投屏视频的播放进度。当用户对子图标97或子图标98操作时可触发视频切换指令，第一设备21将该视频切换指令发送给第二设备22，该视频切换指令包括视频信息列表中的下一个视频的视频信息或上一个视频的视频信息，从而使得第二设备22根据下一个视频的视频信息或上一个视频的视频信息，播放下一个视频或上一个视频。
需要说明的是，如图9所示的投屏控制图标94只是一种示意性说明。通过投屏控制图标94进行投屏控制的方法不限于如上所述的方法。另外，如图9所示的投屏控制图标94的一些子图标可以是复用的。例如，当用户对子图标95进行单击时，可控制投屏视频在第二设备上快进。当用户对子图标95进行双击时，可控制投屏视频的音量增大。例如，当用户对子图标95进行单击时可触发播放进度控制指令，第一设备21将该播放进度控制指令发送给第二设备22，从而使得第二设备22根据该播放进度控制指令，控制第二设备22上播放的投屏视频的播放进度。当用户对子图标95进行双击时，可触发播放音量控制指令，第一设备21将该播放音量控制指令发送给第二设备22，从而使得第二设备22根据该播放音量控制指令控制第二设备22上播放的投屏视频的播放音量。
需要说明的是，当第一设备21处于投屏状态，并且第一设备21当前并未显示投屏控制页时，投屏控制图标94可以是全局显示的。例如，当第一设备21启动其他应用程序时，第一设备21可以显示其他应用程序的用户界面，并在其他应用程序的用户界面上以透明、半透明、悬浮的方式显示投屏控制图标94，从而使得用户可以在控制其他应用程序的同时，还可以对视频投屏进行控制。
此外，用户还可以通过对投屏控制图标94进行操作，控制视频应用程序从后台运行调整到前端运行。当视频应用程序调整为前端运行时，第一设备21的用户界面可以回到如图7所示的用户界面。本实施例并不限定用户对投屏控制图标94的具体操作方式。第一设备21能够区分开用户对投屏控制图标94中子图标的操作和对投屏控制图标94的操作即可。
在一些实施例中，投屏控制图标94在第一设备21上的显示位置可以是固定的，也可以是不固定的。例如，用户可以对投屏控制图标94进行拖拽，从而改变投屏控制图标94的显示位置。
本公开实施例提供的视频投屏方法，第一设备21通过根据用户的后台运行指令，在后台运行视频应用程序，并在第一设备21的用户界面上显示投屏控制图标，该投屏控制图标用于进行投屏控制。即使第一设备21将处于前端运行状态的视频应用程序调整到后台运行状态时，用户还可以通过该投屏控制图标对该视频应用程序的视频投屏进行控制。如此用户可以在控制其他应用程序的同时，还可以对视频投屏进行控制，进一步提高了用户视频投屏控制的便利性。
在上述实施例的基础上，所述方法还可以包括如图10所示的如下几个步骤：
S1001、接收视频切换指令。
在本实施例中，用户可以随时切换投屏到第二设备上的视频。例如，第一设备21当前投屏到第二设备22上播放的投屏视频是如上所述的第二视频，在第二设备22上播放第二视频播放的过程中，用户可以在如图7所示的用户界面上点击其他视频的缩略图或者用户可以点击如图9所示的子图标97或子图标98等触发视频切换指令。例如，用户点击其他视频的缩略图的操作可触发一个视频切换指令，或者用户点击子图标97或子图标98的操作可触发一个视频切换指令。
S1002、响应于所述视频切换指令，将用户选择的目标视频投屏到所述目标设备。
当第一设备21接收到该视频切换指令后，向第二设备22发送第三投屏指令，第三投屏指令包括用户选择的目标视频的视频信息，所述第三投屏指令用于控制第二设备22根据目标视频的视频信息，播放目标视频。例如，该目标视频的视频信息包括该目标视频的视频数据或该目标视频的视频地址。如上述，第二设备22当前播放的投屏视频为第二视频，当第二设备22接收到该第三投屏指令后，停止播放第二视频，并根据第一设备21发送的该目标视频的视频数据播放该目标视频，或者第一设备21根据目标视频的视频地址，获取目标视频的视频数据，并播放该目标视频。
在一种可能的实现方式中，第二设备22在接收到第三投屏指令后，可直接根据目标视频的视频信息，播放该目标视频。例如，第二设备22可以投屏显示目标视频。
在另一种可能的实现方式中，第三投屏指令用于控制所述第二设备22中的第二播放器开启。例如，第二设备22在接收到第三投屏指令后，第二设备22可根据该第三投屏指令启动第二设备22中的播放器，第二设备22中的播放器可记为第二播放器。进一步，第二设备22可以根据目标视频的视频信息，控制第二设备22中的第二播放器，播放该目标视频。
例如，第二设备22当前播放的是第二视频，用户点击了如图7所示的缩略图70，则 第一设备21可以将缩略图70对应的视频的视频信息发送给第二设备22，从而使得第二设备22播放缩略图70对应的视频。如果用户点击了子图标97，则第一设备21可以将第二视频的下一个视频的视频信息发送给第二设备22，从而使得第二设备22播放第二视频的下一个视频。如果用户点击了子图标98，则第一设备21可以将第二视频的上一个视频的视频信息发送给第二设备22，从而使得第二设备22播放第二视频的上一个视频。其中，第二视频的下一个视频或第二视频的上一个视频具体可以是根据如上所述的视频信息列表确定的。视频信息列表中的视频信息的排序可表示相应的视频排序。
如上实施例可知，用户可以通过操作投屏按钮32控制投屏功能开启或关闭。在本实施例中，当第二设备22当前播放的视频是从第一设备21投屏过来的视频时，第一设备21可以默认切换后的视频也是需要投屏到第二设备22的视频。
可选的，第二设备视频切换指令，检测投屏应用程序是否处于投屏状态，当投屏应用程序处于投屏状态时，第一设备21将用户选择的目标视频投屏到第二设备22。
由于用户可以随时通过操作投屏按钮32控制投屏功能开启或关闭，因此在第一设备21接收到用户触发的视频切换指令时，可以检测视频应用程序当前是否处于投屏状态。如果视频应用程序当前处于投屏状态，则第一设备21可以根据该视频切换指令，直接将用户选择的目标视频的视频信息发送给第二设备22，使得第二设备22根据目标视频的视频信息播放目标视频。如果视频应用程序当前不是投屏状态，则第一设备21可以通过第一播放器31对用户选择的目标视频进行正常播放。具体判断过程如图11所示，如图11所示，该过程具体包括如下几个步骤：
S1101、接收视频切换指令。
S1102、判断视频应用程序当前是否处于投屏状态，是则执行S1103，否则执行S1104。
S1103、新视频直接进入投屏状态。
其中，该新视频可以是用户选择的目标视频。新视频直接进入投屏状态具体可以是指第一设备21将新视频直接投屏到第二设备22上进行播放。第一设备21将新视频直接投屏到第二设备22上进行播放后，视频信息列表的更新、以及从视频信息列表中获取下一个视频的视频信息的过程与上述实施例类似，此处不再赘述。
S1104、以正常状态播放新视频。
可选的，目标视频的投屏参数与历史投屏视频的投屏参数一致。第二设备可存储有历史投屏视频的投屏参数，其中，历史投屏视频可以是如上所述的第一视频或第二视频。投屏参数包括如下至少一种：播放进度、分辨率和播放音量。
当第一设备21向第二设备22发送的第三投屏指令不包括用户选择的目标视频的投屏参数时，第二设备22可以按照历史投屏视频的投屏参数对目标视频进行播放。可选的，目标视频的分辨率与切换之前投屏到所述第二设备的视频的分辨率一致；和/或所述目标视频的播放音量与切换之前投屏到所述第二设备的视频的播放音量一致。例如，第二设备22按照播放第二视频时所用的投屏参数，播放目标视频。举例说明，第二设备22播放第二视频时的分辨率为高清，播放音量为6，第二设备22播放目标视频时的分辨率为高清，播放音量为6。
需要说明的是，用户选择的目标视频可以是视频合集中的任意一个视频。该视频合集是一部完整的电视剧。第二设备22可以连续播放该视频合集中的每一个视频。如果第二设备22已经播放到了该视频合集中的最后一个视频，则播放完该最后一个视频后，可以从该视频合集的第一个视频重新开始播放。
在一些实施例中，当第一设备21在竖屏模式下，由于第一播放器31占用的面积较小，第一设备21的用户界面上可以显示视频合集的多个视频图标。此时，用户可以单击视频合集中的任意一个视频图标，进行投屏的视频切换。当第一设备21在横屏模式下，由于第一播放器31占用的面积较大，可能无法显示视频合集的视频图标，第一设备21的用户界面可以显示“选集”图标。当用户点击“选集”图标时，该用户界面可以显示视频合集的多个视频图标，用户可以单击任意一个视频图标，以切进行投屏的视频切换。
本公开实施例提供的视频投屏方法，第一设备21根据视频切换指令，检测视频应用程序是否处于投屏状态；当视频应用程序处于投屏状态时，则将用户选择的目标视频的视频信息发送给第二设备22，使得第二设备22播放目标视频。当视频应用程序不处于投屏状态时，第一设备21通过该第一设备21的第一播放器31播放该目标视频，而不再控制第二设备22播放该目标视频。第一设备21通过在将视频进行投屏之前，先检测视频应用程序是否处于投屏状态，当视频应用程序处于投屏状态时，直接投屏。当视频应用程序不处于投屏状态时，则不进行投屏，从而避免用户关闭投屏设备的投屏功能后，第一设备21继续进行视频投屏导致的错误操作，保证了视频投屏的正确性。同时，也保证了用户在执行一次投屏操作后，不需要反复执行投屏操作即可使得第二设备连续投屏播放。
另外，用户选择的目标视频的投屏参数与切换之前第二设备上播放的投屏视频的投屏参数一致，减少用户对目标视频的投屏参数的配置次数，用户无需对切换后的目标视频的投屏参数进行重新配置，也能够使第二设备按照用户的习惯播放目标视频，符合用户的需求。进一步节省了用户的时间，提高了用户体验。
