Abstract


Video call technology matures, has been able to basically meet the people's daily life instant communication . However, in today's increasingly rich material civilization , spiritual civilization, people are increasingly seeking to improve . The purpose of using video calls are not only satisfied with a simple communication, people also want to be able to video call at the same time add some fun. The main use DirectShow technology and OpenGL technology combines video communication software design and implementation. Using DirectShow video communication as the basic framework , the software can well guarantee the Windows system running well and good hardware compatibility . Effects processing using OpenGL as a tool for video special effects processing to the GPU for processing, not only can get very good results, do not have a greater impact on system resources . In the software function, screen communication software implemented to meet the following functions: a ) audio processing . In the audio sender and receiver side volume control and sound shield settings. 2 ) video processing . You can set the video brightness , saturation and contrast and other basic parameters , can capture both local and remote video capture , you can set the video window is displayed, you can send the video screen , you can play video files to each other. You can also set video effects , which is the main task of this paper . Way video effects settings will contain video information OpenGL scene as a local video source to communicate. The user can simply select the type of effect , to achieve a variety of different types of effects such as local or global contrast , hue , color changes , a variety of different shapes, different transparency, borders , various effects produced by the particle system , such as fireworks, rain, snow, fog and so on. While users can precisely control and adjust various parameters of these effects and to obtain satisfaction personalized results.
