| 摘要: |
| 采用Windows平台下的Direct Show组件技术,以及MPEG-4和DSP Group True Speech(TM)视音频压缩算法,在Visual C++6.0开发环境下实现从摄像头捕捉视频,从麦克风捕捉音频,并将视音频数据压缩后合并输出到AVI文件。数据压缩比达到100:1,节省了存储空间,实现了视频的预览。 |

| Abstract: |
| Based on Directshow,a system is developed using MPEG-4 and DSP group truespeech(TM) encoding algorithms in visual C++6.0.The system implements video and audio real-time capture and preview and saves them as an AVI file.For its high compression ration(nearly 100:1),it reduces memory space greatly. |
