Abstract

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.

Description

technical field [0001] The present invention relates to the field of live broadcast, in particular to a method and device for screen recording and live broadcast based on mobile equipment, mobile equipment and a live broadcast system. Background technique [0002] With the development of hardware and communication networks of mobile devices such as smartphones and IPADs, and the gradual increase in the awareness of domestic mobile game players, the trend of heavy mobile games is becoming more and more obvious. While more and more MOBA and FPS mobile games are appearing, a new industry has also been born - "mobile game live broadcast". An authoritative data agency predicts that the scale of China's game live broadcast market will reach more than 5 billion yuan in three years, of which mobile game live broadcast will account for more than 30% of it. [0003] At present, mobile game live broadcasting is mainly to record the game screen and sound of the mobile device by install...
