中文摘要: 在TMS320DM642 平台上实现了能够实时处理分辨率为1024×768, 60Hz 视频图像的H.264 视频编码器.解决了DM642 平台下大分辨率视频图像的接入问题, 根据DM642 的片内资源设计了存储器分配方案, 并针对视频采集驱动和H.264 视频编码器提出了一套优化解决方案. 测试结果表明, 对于1024×768 这种大分辨率视频图像, H.264 编码器的处理速度能够满足视频编码的实时处理要求.
Abstract:In this paper, optimization of a H.264 encoder and video capture driver using TMS320DM642 are presented, and some speciality are considered according to the analysis of the video capture driver structure and the architecture of DM642. The problem of dealing with high definition video, such as video frame of 1024×768 resolution, is finally resolved based on DM642. The testing results demonstrate that encoder has sped up remarkably after optimization, which can meet the real-time encoding requirement for the video resolution of 1024×768.
