摘要
针对基于视频的路产管理系统需要实时同步播放多路复合视频的特点,设计了一款基于ActiveX技术的多功能视频播放器,该播放器通过数据库关联技术实现了每一帧视频图像的精确定位,并采用多线程边下载边播放技术实现了在Web环境的应用。该播放器已经成功应用于某路产管理系统中,使用表明:该播放器使用简单、视频播放流畅、帧定位效率高。
In order to solve the synchronous and real-time playing of multi-channel videos in road asset management system,a multimedia player base on ActiveX control technology is developed.The player realizes the accurate locating of reach video frame through database relevance technology.With the multi-thread and playing-when-downloading technology,it can be used in a web environment.The player has been successfully applied in a road asset management system.Experiment results prove that the player can be easily operated with high locating efficiency.
