Developing a software system through integrating existing applications becomes mature and practical There is already a huge number of multimedia applications today However, few studies focus on integrating stream-based multimedia applications into a software system This paper therefore aims to integrate software for applications with multimedia audio/video streams through a wrapper technique In wrapping multimedia applications, a virtual device approach is used to intercept/redirect the audio/video streams The wrapper modules are designed for audio and video applications based on two media device interfaces, ALSA and V4L in Linux, respectively The DMA synchronization between multimedia applications is a critical issue To demonstrate the feasibility of the proposed approach, a voice control information system for high speed rail was developed by integrating two audio media applications Skype and Sphinx
