| 摘 要： | 研究开发了能将标准模拟视频信号实时采集存储到硬盘上,并且可以完成预览功能的视频流捕获系统.该系统可按用户对图像质量和输出文件大小的不同要求,通过选择DirectShow的压缩过滤器,输出不同格式的视频文件.按Fusion878A视频流捕获卡的开发和内核级WDM设备驱动程序的开发,实现捕获和预览功能的用户级DirectShow应用程序的开发,阐述了系统的实现过程.试验证明,该系统能够实时将输入的模拟视频信号捕获并以文件的形式存储在硬盘上,同时也实现了对输入模拟视频信号的预览功能,图像显示清晰、流畅.

| Abstract: | Developes a new system used to capture the live composite video signal to the hard disk and preview it in real time. The development process is described in three steps. Firstly, development of the capture and preview hardware adapter based on the Fusion878A. Secondly, develoment of the kernel WDM driver for the hardware adapter. Finally, development of the DirectShow application software. In every step the technical procedures and difficulties are described in detail. The video stream capture and preview system has been developed successfully. Experiments proved that the system can capture composite video signals and save it as files in the hard disk, and the system can preview the video signal. |
