摘要
将ARM与DSP相结合,研究和实现了一套嵌入式实时视频传输系统。以集成ARM和DSP双内核的OMAP3530作为核心处理器,通过ARM上搭载的Linux操作系统实现基于V4L2的图像采集功能,调用DSP完成H.264视频编码,压缩后的图像由基于实时流传输协议的流媒体服务器传输至远程计算机端解码并显示。测试结果表明,该系统具有较好的实时性和扩展性,有广阔的应用前景。
The research and implementation of a video transmission system based on ARM and DSP are introduced. The system uses chip OMAP3530 which is a dual-core processor as its CPU. The program of capturing pictures runs on Linux for ARM based on V4L2. Then, the pictures are encoded to the H. 264 format by the DSP. The encoded images are transferred to the remote computer by the stream media server based on RTSP. The experimental results show that the system has good real-time performance and expandability, and it has broad application prospects.
