摘要
基于Au1200设计无线车载媒体处理系统,介绍系统中视频监控部分的设计方案,提出基于ffmpeg的软压缩方法,设计并实现了视频监控的实时采集、压缩和存储。利用ffmpeg软压缩方法,将采集到的视频数据实时压缩成视频文件存储于硬盘中,降低了系统成本,对实际嵌入式媒体处理系统的开发具有较大价值。
A video monitoring design scheme which is a part of wireless multimedia processing system On vehicles based on Au,1200 is introduced. The real - time capture, compression and storage of video monitor is designed and implemented based on ffmpeg software compression method, The data of real - time capture is compressed to video files by ffmpeg method and stored on hard disk. The method can reduce system cost and it is valuable in the actual embedded media processing systems.
