Data Flow Synchronous Transmission of Video Capture Based on DM368

A video capture system often encounters the problem of lacking smoothness of video. A video capture system is usually composed of the image capture,image resizing,auto exposure,auto white balance,video compression and encoder,video stream and other modules. In this paper,the problem of data synchronization between these module is addressed based on complementing a video capture system. Utilizing the completion mechanism,the synchronized transmission of the data flow is implemented through reasonably scheduling the buffer between different modules. The test result manifests that the video acquired by this system runs fluently,and has high resolution and fine color reducibility. and the system runs stably.
