具体实施方式
下面结合说明书附图对本申请实施例所提供的数据传输方法、系统、装置、电子设备及存储介质进行详细的解释和说明。
在本申请实施例中，终端设备包括但不限于笔记本电脑、智能手机、平板电脑以及台式电脑中的至少一种，会议应用例如为一种安装于终端设备上的会议软件，第一数据传输应用也安装于终端设备上，具有设备同步功能或共享外设功能，通过该功能可以获取目标设备的摄像头采集的数据。目标设备包括但不限于智能交互平板(例如：会议室中的会议平板)或者其他具有摄像头的电子设备，并可具有内设或外设的大广角、高性能的摄像头；第二数据传输应用安装于目标设备上，也具有相应的设备同步功能或共享外设功能。终端设备和目标设备，可通过第一数据传输应用和第二数据传输应用进行数据的传输和/或共享。
在会议室中终端设备通过会议应用进行视频会议的场景下，由于受终端设备自身摄像头的广角和/或采集画质等因素的影响，有时需要通过终端设备上安装的传屏应用来调用外部设备摄像头的画面，例如会议室中会议平板的摄像头采集的画面，一般会议平板的摄像头广角大，可以采集整个会议室的会议场景(例如：所有参会人员的表情、动作等，会议过程中需要展示的物品等)，而且大部分情况下会议平板的摄像头往往比用户终端设备自身摄像头的性能更加优越。
现有技术中，在上述会议场景下，终端设备的用户出于习惯，往往首先想到的是打开会议应用，而非打开传屏应用。故，此时即使用户在会议应用的界面，对照相机功能进行设置选择：虚拟摄像头(也可为：Sharing Camera，即传屏应用的虚拟摄像头，此处可参见图3)，由于虚拟摄像头对应的缓存中没有被灌入数据，此时会议应用显示的是黑色画面。这正是由于用户习惯在开会前先去打开会议应用进行选择，而非先手动打开终端设备上的传屏应用并启动其上的设备同步功能或共享外设功能，这就导致无法通过终端设备的传屏应用与会议平板端对应的传屏应用建立连接，进而获取会议平板端的摄像头画面，也无法将该画面灌入虚拟摄像头对应的缓存中，会议应用无法从虚拟摄像头对应的缓存中读取相应的数据。可见，在上述使用场景下，现有的操作并不符合用户的使用习惯，导致终端会议应用常常出现的黑色画面会给用户带来困扰，使得用户会议的体验感差。
基于现有技术中存在的技术问题，提出本申请实施例的方案。
本申请至少一个实施例提供了一种数据传输方法，实现媒体数据的便捷传输。数据传输方法包括但不限于如下的步骤：响应对会议应用的虚拟摄像头选项的选择操作，控制第一数据传输应用启动；会议应用和第一数据传输应用运行于终端设备上；通过第一数据传输应用与第二 数据传输应用连接，建立终端设备与目标设备之间的通信连接；第二数据传输应用运行于目标设备上；通过第一数据传输应用向第二数据传输应用发送媒体数据获取指令；第二数据传输应用基于接收到的媒体数据获取指令，获取目标设备的摄像头采集的第一媒体数据，并将第一媒体数据发送至第一数据传输应用；通过第一数据传输应用将第一媒体数据传输至会议应用，以在会议应用上显示与第一媒体数据对应的画面。可见本申请实施例实现了在用户打开会议应用和选择虚拟摄像头选项后，自动控制第一数据传输应用启动，通过第一数据传输应用与第二数据传输应用，建立终端设备与目标设备之间的通信连接，并为会议应用提供用于形成视频画面的第一媒体数据(即目标设备摄像头的数据)，避免了常规方案中用户经常遇到的打开会议应用并选择虚拟摄像头选项之后显示画面是黑色的问题。可见本申请实施例提供的技术方案实现了在视频会议场景中自动跨设备调用摄像头，简化了用户操作，明显提升用户的视频会议体验和用户满意度。本申请实施例充分利用了目标设备的摄像头在硬件性能上的优势，为参加视频会议的用户提供更好的视频效果和会议效果等。
如图1所示，本申请一个或多个实施例能够提供一种数据传输方法，该数据传输方法包括但不限于步骤S100至步骤S500。
步骤S100，响应对会议应用的虚拟摄像头选项的选择操作，虚拟摄像头驱动发送数据请求指令至服务模块。
具体地，响应对会议应用的虚拟摄像头选项的选择操作，虚拟摄像头驱动发送数据请求指令至服务模块，可包括：会议应用响应虚拟摄像头选项的选择操作，则向虚拟摄像头驱动发送数据请求指令，然后虚拟摄像头驱动转发数据请求指令至服务模块。其中，本实施例中的服务模块是指一种随着第一数据传输应用的安装而安装于终端设备上的系统服务，终端设备包括但不限于笔记本电脑、智能手机、平板电脑以及台式电脑中的至少一种，会议应用例如为一种安装于终端设备上的会议软件。其中，虚拟摄像头驱动也是随着第一数据传输应用的安装而安装于终端设备上的，例如为Virtual Camera驱动程序等，具体在此不做限定。随着终端设备启动运行，虚拟摄像头驱动和服务模块均在后台自动运行，且服务模块自动与虚拟摄像头驱动建立连接。本申请实施例中的虚拟摄像头驱动位于终端设备的驱动层，则服务模块和第一数据传输应用均可通过驱动层的本地端口和本地地址(例如127.0.0.1)与虚拟摄像头驱动连接。
步骤S200，响应数据请求指令，服务模块控制第一数据传输应用启动；会议应用、第一数据传输应用、虚拟摄像头驱动及服务模块运行于终端设备上。
具体地，本申请实施例服务模块响应数据请求指令的方式可包括：利用ShellExecute(一种用于控制外部程序打开的应用程序接口函数)自动打开第一数据传输应用，当然并不限于此。
步骤S300，通过第一数据传输应用与第二数据传输应用的连接，建立终端设备与目标设备之间的通信连接；第二数据传输应用运行于目标设备上。
具体地，通过第一数据传输应用与第二数据传输应用的连接，建立终端设备与目标设备之间的通信连接，可以采用以下方式：在第一数据传输应用的界面中手动输入连接码，也可从该界面所显示并搜索到的可连接的设备中进行选择，若只有一个可连接设备，也可自动进行连接；若界面显示的设备在历史记录中连接过，则还可同时显示历史上的连接时间；当然还可有其他方式，并不限于此。通过上述方式，第一数据传输应用可向第二数据传输应用获取地址(IP，Internet Protocol，网际互连协议)信息和端口(Port)信息，以基于该地址信息和端口信息，通过传输控制协议(TCP，Transmission Control Protocol)方式建立终端设备与目标设备之间的通信连接。其中，本申请可选实施例中的第一数据传输应用可以是数据传输应用客户端(Client)，第二数据传输应用可以是数据传输应用服务端(Server)，该数据传输应用：可以是一种具有设备同步功能或共享外设功能的应用，包括但不限于传屏应用。
步骤S400，通过第一数据传输应用向第二数据传输应用发送媒体数据获取指令；第二数据传输应用基于接收到的媒体数据获取指令，获取目标设备的摄像头采集的第一媒体数据，并将 第一媒体数据发送至第一数据传输应用。
具体地，通过第一数据传输应用向第二数据传输应用发送媒体数据获取指令，包括：在步骤S300后，第一数据传输应自动开启设备同步功能或共享外设的功能，并向第二数据传输应用发送媒体数据获取指令。第二数据传输应用响应于接收到的媒体数据获取指令，可以在目标设备的屏幕上弹出对话窗，与会者可通过对话窗中的同意选项和/或不同意选项，选择同意或拒绝终端设备调用目标设备的摄像头。其中，响应用户对同意选项的操作，第二数据传输应用基于媒体数据获取指令，可向目标设备的摄像头发送采集第一媒体数据的指令，目标设备的摄像头响应该指令将第一媒体数据发送给第二数据传输应用，第二数据传输应用进行压缩及编码后将第一媒体数据发送至第一数据传输应用。可选的，目标设备的摄像头采集的视频数据可以为RGB格式，经过第二数据传输应用进行编码后压缩得到H264格式的视频数据。反之，响应用户对不同意选项的操作，第二数据传输应用不再执行相应的操作。此外，本申请可选的实施例中在第二数据传输应用配置中设置默认同意选项，以默认允许终端设备调用目标设备的摄像头。
步骤S500，通过第一数据传输应用发送第一媒体数据至虚拟摄像头驱动，以在会议应用上显示与第一媒体数据对应的画面。
具体地，第一媒体数据，例如可为经第二数据传输应用进行编码后压缩得到的H264(高度压缩数字视频编解码器标准)格式的数据流，并可以通过FFmpeg(一种具有视频格式转换功能的多媒体视频处理工具)方式对第一媒体数据进行解码，以将H264格式的数据流解码为YUV(一种可用于记录彩色图像的格式)格式的数据流，解码过程还可包括通过libyuv(一种视频格式转换工具)将YUV格式的数据流转换为RGB24(24位RGB)格式的数据流，以得到解码后的第二媒体数据。其中，本实施例第一数据传输应用对第一媒体数据进行解码过程中，可按照数据请求指令中包含的视频长度、视频宽度、视频大小的格式要求进行数据转换，以得到第二媒体数据。本申请实施例将第二媒体数据存储于驱动层中预先为虚拟摄像头模块分配的存储空间(Buffer，即虚拟摄像头驱动的缓存)，会议应用从Buffer中获取第二媒体数据，以及利用获取到的第二媒体数据形成画面。
综上，本申请的实施例，在用户在终端设备打开会议应用并选择虚拟摄像头选项后，在摄像头驱动和服务模块的支持下，能够自动开启第一数据传输应用及其设备同步功能或共享外设功能，进而与目标设备的第二数据传输应用建立通信连接，以获取目标设备的摄像头采集的媒体数据，使得会议应用能够自动调用并显示外部目标设备的摄像头采集的媒体数据，避免了现有技术中操作复杂，不符合用户习惯，且往往导致用户打开会议应用并选择Sharing Camera之后画面是黑色，给用户带来困扰和不便的问题。本申请通过响应会议应用的Sharing Camera选择操作，自动控制第一数据传输应用及其功能的启动，简化了用户手动操作，整个流程更加符合用户使用习惯，提升了用户视频会议体验和满意度；此外，还明显提高了目标设备的摄像头的利用率。
在本申请一个或多个实施例中，该数据传输方法还包括：服务模块控制第一数据传输应用启动之前，或者，在第一数据传输应用接收到第一媒体数据之前，则通过服务模块发送预设图片至虚拟摄像头驱动，以在会议应用上显示与预设图片对应的画面。
具体地，随着终端设备启动运行，虚拟摄像头驱动和服务模块均在后台自动运行，且服务模块自动与虚拟摄像头驱动建立连接。其中，虚拟摄像头驱动位于终端设备的驱动层，则服务模块可通过驱动层的本地端口和本地地址(例如127.0.0.1)与虚拟摄像头驱动连接。然后，服务模块向虚拟摄像头驱动发送验证数据包；通过虚拟摄像头驱动对验证数据包进行验证；如果验证通过，虚拟摄像头驱动向服务模块发出第一应答指令(表明验证成功的指令)；第一应答指令表示服务模块具有向虚拟摄像头驱动写入数据的权限；如果验证未通过，则通过虚拟摄像头驱动向服务模块发出第二应答指令(表明验证失败的指令)；第二应答指令表示服务模块没有向虚拟摄像头驱动写入数据的权限。同时，服务模块中保存有预设图片，如果验证通过，则 服务模块将预设图片的数据写入虚拟摄像头模块分配的存储空间(Buffer，即虚拟摄像头驱动的缓存)中，会议应用选择Sharing Camera时，可以从Buffer中获取预设图片的数据，以及利用获取到的预设图片的数据形成画面。其中，预设图片编码例如可为RGB24(24位RGB)格式的数据流，从而在会议应用的界面上形成画面。在本申请一个或多个实施例中，预设图片具有用于引导用户操作的文字信息和/或用于引导用户操作的图示信息。例如，文字信息例如可以是引导用户下载和/或使用传屏应用的文字介绍，图示信息例如可以是引导用户下载和/或使用传屏应用应用的操作示意图等。本申请实施例可基于上述的方案在未成功获取第一媒体数据的情况下通过预设图片引导用户进行相应的操作，例如可告知用户按照输入PIN码(一种连接码)的方式手动建立终端设备与目标设备之间的连接，和/或，可以手动启动第一数据传输应用(即数据传输应用客户端(Client))界面的设备同步功能或共享外设的功能，设备同步功能或共享外设的功能包括但不限于：数据传输应用客户端基于上述连接获取到数据传输应用服务端的摄像头采集的视频数据。本实施例基于上述方式提高访问虚拟摄像头驱动的可靠性，保证向虚拟摄像头驱动中写入的数据为本申请实施例待使用的媒体数据。同时，解决了在通过第一数据传输应用获得目标设备的摄像头采集的数据之前，终端设备在会议应用界面选择Sharing Camera选项后，显示黑色画面对用户造成的困扰，提升了用户会议的体验和满意度。
在本申请一个或多个实施例中，该数据传输方法还包括：当第一数据传输应用接收到第一媒体数据，第一数据传输应用向服务模块发送断开指令；服务模块在接收到断开指令后，服务模块对断开指令进行响应，具体断开与虚拟摄像头驱动的连接，以停止向虚拟摄像头驱动发送预设图片，之后第一数据传输应用将经过处理的第一媒体数据发送至虚拟摄像头驱动，即满足终端设备会议应用使用目标设备的摄像头的需求。
在本申请一个或多个实施例中，通过第一数据传输应用发送第一媒体数据至虚拟摄像头驱动之前，还包括：第一数据传输应用通过驱动层的本地端口和本地地址与虚拟摄像头驱动建立连接；然后，通过第一数据传输应用向虚拟摄像头驱动发送验证数据包；通过虚拟摄像头驱动对验证数据包进行验证；如果验证通过，则通过虚拟摄像头驱动向第一数据传输应用发出第一应答指令(表明验证成功的指令)；第一应答指令表示第一数据传输应用具有向虚拟摄像头驱动写入数据的权限；如果验证未通过，则通过虚拟摄像头驱动向第一数据传输应用发出第二应答指令(表明验证失败的指令)；第二应答指令表示第一数据传输应用没有向虚拟摄像头驱动写入数据的权限。本实施例能够通过上述的方式提高访问虚拟摄像头驱动的可靠性，避免验证不通过的应用向虚拟摄像头驱动写入数据，保证向虚拟摄像头驱动中写入的数据为本申请实施例待使用的媒体数据。
在本申请一个或多个实施例中，通过虚拟摄像头驱动对验证数据包进行验证，包括：通过虚拟摄像头驱动对验证数据包进行解析，以解析出进程标识号(ID，Identity Document)；校验进程标识号是否为终端设备上的应用层的进程标识号，具体判断进程标识号是否存在于终端设备的进程列表中；若是，则确定验证通过，说明第一数据传输应用为运行于终端设备的应用层上的应用；若否，则确定验证未通过，说明第一数据传输应用不是运行于终端设备的应用层上的应用。基于上述改进之后的技术方案，本申请实施例还能够避免非应用层的程序或者应用对驱动层的访问，提升了本申请实施例的安全性。
在本申请可选的实施例中，通过第一数据传输应用与第二数据传输应用连接，建立终端设备与目标设备之间的通信连接，包括：如果目标设备数量为一个，通过第一数据传输应用与当前的目标设备上的第二数据传输应用连接，建立终端设备与当前的目标设备之间的通信连接；如果目标设备数量为多个，根据用户的选择操作或者设备连接历史信息确定待连接的目标设备，通过第一数据传输应用与待连接的目标设备上的第二数据传输应用连接，建立终端设备与待连接的目标设备之间的通信连接。本实施例根据设备选择操作确定待连接的目标设备，具体为：在第一数据传输应用界面上，显示搜索到的所有目标设备的列表，响应用户基于点击或触控的 设备选择操作，确定与该设备选择操作对应的目标设备作为待连接的目标设备。本实施例搜索目标设备的方式包括基于简单服务发现协议(SSDP，Simple Service Discovery Protocol)方式搜索在当前局域网内的目标设备，将搜索到的目标设备添加到列表中。根据设备连接历史信息确定待连接的目标设备，具体为：历史信息中包含上次连接的目标设备的信息，本次连接可自动连接上次连接的设备。本申请实施例能够基于上述的方案满足用户快速连接目标设备的需求，满足用户调用所需的目标设备的摄像头的需求，提升了用户满意度。本申请实施例不仅明显提升了用户的操作效率，而且可为用户提供可选择的多个目标设备，用户仅在终端设备上登录会议应用的账号即可，而无需在目标设备上登录会议应用的账号情况下即可使用目标设备的摄像头，提高了会议应用的账号安全性，提升了用户体验。
如图3所示，会议应用中可具有设备设置选项(右侧的×用于关闭该选项)，在设备设置选项下可进行音频设置和视频设置，音频设置例如可包括音频设备、扬声器、麦克风的选择设置，结合本申请实施例的视频设置可在照相机选项(包括虚拟摄像头选项)中选择对应的虚拟摄像头，在点击该选项之后，第一数据传输应用及设备同步功能会被自动打开，成功获得目标设备摄像头的数据后写入虚拟摄像头模块分配的存储空间(Buffer，即虚拟摄像头驱动的缓存)中，此时会议应用显示的视频画面为对应于该虚拟摄像头模块的画面；该示例为某会议应用的界面示意，当然并不限于此。
