摘要
介绍了Linux环境下实现视频采集、传输、显示的原理和工作流程,对Linux环境下使用V4L2实现视频采集的过程进行了详细的分析,对Socket编程实现网络通信和SDL中的视频显示API进行了深入的研究,进而实现了在服务器端使用USB摄像头捕获实时图像,通过网络传输,将图像数据传送到客户端进行实时显示。
Introduce the theory and procedure to accomplish the video capture,transmission and display in Linux.Give an detail analysis of using V4L2 to attain video capture in Linux,and make an in-depth research of the Socket and the SDL video programming.At last implement the whole system by using the USB camera to capture the real-time image on the server,sending the image data to the client through the network,and real-time displaying.
