摘要
实时视频采集和压缩是多媒体应用的核心。用软件实现实时视频采集和压缩避免了使用特定硬件的限制,易于修改,开发成本低。介绍了基于VFW和DirectShow开发实时视频采集的软件技术,并利用第三方提供的编、解码器进行实时压缩,并给出了相应的试验结果。
Video capture and compression is the core of the application of the multimedia. Compared with hardware, the software method avoids the limitation of the special device and is apt to modify. It also cost less. This paper introduces two me thods of real-time video capture based on the VFW and DirectShow. With the help of the Codec such as MPEG-4 offered by the third part, we can also compress the real-time video.
