摘　　要：针对车载播放系统立体性、互连性、智能性的多方向发展趋势,研发了一套基于QNX的车载立体播放系统。采用实时性在微秒级的QNX系统作为软件平台;提出系统分层逻辑架构模型,增强模块间的独立性;利用FFMPEG核心技术完成立体视频解码,满足多码流同步实时输出;设计GLES立体渲染容器进行同步实时渲染。实验表明,该方案在有效提高车载视频观感的同时,极大地提升了整个车系的科技竞争力。With the multi-directional development of the vehicle playback system,three-dimensional,connectivity,intelligent become the main trends. A vehicle stereo playback system based on QNX is researched. The QNX of microsecond real-time system is used as the software platform. A layered logical architecture model is proposed to enhance the independence between modules. In order to meet the needs of simultaneous real-time output, FFMPEG technology is used to complete the stereo video decoding. GLES stereo rendering container is designed to synchronize real-time rendering. The experi- mental results show that the program effectively improves the look and feel of the vehicle video, and also greatly enhances the technological competitiveness of the entire vehicle type.
