Abstract: Aiming at the characteristics of the traditional virtual camera technology needs driver’s support, this paper proposes a virtual camera development framework based entirely on the DirectShow technology. It analyzes the DirectShow and WDM technology’s features, focuses on discussing the key technology of implementation, and gives a practical application case. Software development based on this framework can reduce the virtual camera’s costs of development and maintenance, and it has good scalability.

Key words: virtual camera, DirectShow technology, driver model
