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。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 Rood scalability.
