| Abstract: | 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. |
