摘要
视频应用程序的GUI与视频无法同时显示,在对此问题分析的基础上,提出了Linux平台上基于软件实现的在屏显示技术OSD(On Screen Display)混合器的视频应用程序框架,讨论了实现的关键技术。并针对该混合器移植开源GUI,为视频应用程序的界面设计提供API。应用实例表明,实时性、交互性和复杂度均比较理想。
GUI of video applications cannot be displayed together with the video simultaneously in same area.After analyzing this issue,a framework for video application of OSD（on screen display） mixer implemented on Linux platform based on software is presented,and the key technologies pertaining to the implementation are discussed as well.Furthermore,an open source GUI is transplanted to this OSD mixer, which provides the design of video application interfaces with API.Application tests show that the real-time,interactivity and complexity are all quite satisfied.
