Live recorded screen broadcasting method, live recorded screen broadcasting device, mobile device and live broadcasting system

The invention discloses a method and a device for broadcasting recorded screen live on the basis of a mobile device, a mobile device and a live broadcasting system. An application interface OpenGL ES is utilized to acquire first screen data corresponding to the screen picture of the mobile device according to a preset first frame rate, the acquired first screen data are encoded, so that encoded first video data are obtained, and the first video data are encapsulated into a first RTMP (Real-Time Messaging Protocol) data packet. Thus, by acquiring screen picture according to the preset frame rate, video data with a stable frame rate can be obtained, video data with a stable code rate can be obtained by encoding the video data, and thereby the smoothness of the video data played by a viewing side player can be improved. 本发明公开了种基于移动设备进行录屏直播的方法和装置、移动设备及直播系统。利用应用程序接口Opengl ES以预设的第帧频采集所述移动设备的屏幕画面所对应的第屏幕数据，对采集得到的所述第屏幕数据进行编码，以得到编码后的第视频数据，并将第视频数据封装成第RTMP数据包。由此，通过以预设的帧频采集屏幕画面，可以得到稳定帧频的视频数据，对该视频数据进行编码，就可以得到稳定码率的视频数据，从而可以
