Porting Of Software PHOENIX On Raspberry Pi

With the rapid development of the economy,information technology continues to progress and the popularity of smart home.The rapid development of embedded technology and the promotion of the concept of Internet of Things to promote more and more equipment with the "smart" and "network" linked together;smart home is the product of this trend.Now,Linux kernel-based systems are widely used on smartphone smart TVs and tablets.For low power consumption,high efficiency,stability of the multimedia mobile platform,this article for the Raspberry pi to achieve a portable energy efficient smart TV system(set top box).This paper mainly studies the development process of embedded Linux application system.Which include cross-compiler environment to build embedded Linux transplant,conceptions of the player and serviceplan program,using of Qt,the establishment of embedded web server.From the choice of cross-compiler tools,the existing system(PHOENIX)in the transplant procedures,video streaming media decoding and other aspects of analysis,the first cross-compiler tool selection is based on efficient and efficient,simple operation and experience to choose--Buildroot,which is a set of Makefiles and a series of patches that can easily build the target's cross-compilation toolchain,root filesystem,and kernel image.Related PHOENIX system software porting is based on QT5 programming software development and modification.General streaming media is encrypted to protect,so to solve this encrypted streaming media issues,choose to use TNT,M3U8,RTP and other media streams.As well as the final display of each software is responsible for the wayland.Expected results:Produce a practical application based on embedded Linux smart TV system(TV box).Real-time streaming of video streams and local media files.
