DirectShow Video Mixing Renderer 9 Description

The DirectShow Video Mixing Renderer 9 application was developed to be a small test tool that will dynamically mix two video files (.mpeg, .mpg, .avi and .dat). Mixing involves alpha-blending and stretching/shrinking and positioning of the two video streams, individually, using DirectShow's VMR9 filter. The two video streams, one on top of the other, are rendered on a single surface. This surface, in our case, is a PictureBox control. Each stream's alpha value, position and height/width can be adjusted at runtime.Additional InformationThe second video stream opened is on top of the first one, i.e., file-2 video is rendered on top of file-1 video. Therefore, if the first video's alpha value is a 100% and the second video's alpha value is 50%, then both videos will be equally (50%) visible. It should be noted that the values of Width and Height of trackbars can run into negative values. So when a video stream's width is -100%, it is laterally inverted. Similarly, when a video stream's height is -100%, the video is upside down.
