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

摘要： 针对传统虚拟摄像头技术需要驱动程序支持的特点，提出一种完全基于DirectShow技术的虚拟摄像头开发框架。分析DirectShow和WDM的技术特点，论述其实现过程中的关键技术，给出一个实际应用案例。基于该框架的开发方案减轻了虚拟摄像头的开发和维护成本，具有良好的可扩展性。
