【摘要】：随着科技社会的发展,安防监控领域视频设备的高清化已成为新的发展趋势。采用TI最新推出的达芬奇单片系统TMS320DM8168,设计了一套高清视频监控系统。主要介绍了V4L2在该系统中的实现,主要包括视频接口设计、V4L2采集设备驱动开发和V4L2采集应用程序设计等内容。测试结果表明该系统中实现的V4L2驱动和应用程序能够为DM8168高清视频监控系统提供高清视频数据,具有良好的可靠性和稳定性。
[Abstract]:With the development of science and technology, the high-definition video equipment in the field of security surveillance has become a new development trend. A high-definition video surveillance system is designed by using TI's latest da Vinci monolithic system TMS320DM8168. This paper mainly introduces the implementation of V4L2 in this system, including the design of video interface and the development of V4L2 acquisition device driver and the design of V4L2 acquisition application program. The test results show that the V4L2 driver and application program in this system can provide high-definition video data for DM8168 high-definition video surveillance system, and it has good reliability and stability.
