基于DaVinci和Gstreamer技术的视频播放系统设计

摘要

The goal of this design is to develop a real-time streaming video playback subsystem for the video processing platform which is based on DaVinci TMS320DM355. Gstreamer framework to develop the plugin of TMS320DM355 is used in this system.It can decode the AVI video file which is MPEG-4 encoded and then output the video stream to TV set to display. At the same time, infared module (MSP430) for remote control and employs OSD to develop system's user interface is utilized. Finally, the goal to implement a fully functional player is achieved.%目标是在以DaVinci TMS320DM355为核心的视频处理平台上实现视频流的实时播放.将采用Gstreamer框架结构开发TMS320DM355芯片的插件,实现经MPEG-4压缩后的AVI格式多媒体数据流的解码,并输出到电视机上播放.同时使用红外模块MSP430进行遥控,利用OSD开发系统界面.最后实现了一个功能完善的播放系统,达到了开发目的.
