The question is being asked from time to time. Everyone knows what is full screen video. Video renderers implement full screen capability since long ago through their IVideoWindow::put_FullScreenMode property, and even Filter Graph Manager exposes its own IVideoWindow interface to forward calls to filter’s implementation of IVideoWindow interface. However, for Video Mixing Renderers, version 7…
A 100-lines code snippet which illustrates how a bitmap is overlaid over displayed video with Video Mixing Renderer 9 Filter using IVMRMixerBitmap9 interface. A video clip is played (default is Windows clock.avi, but you can replace it with your longer one to see overlay is really in a loop). http://code.assembla.com/…/VmrMixerBitmapSample01/… VMR9AlphaBitmap AlphaBitmap; ZeroMemory(&AlphaBitmap, sizeof AlphaBitmap);…
Recently it was the time to sort out an issue with a video DMO, which outputs YV12 video and in the same time is capable of supporting extended video strides in order to efficiently make a direct connection to Video Mixing Renderer Filters. From past experience, I already knew that some bugs are definitely involved…
This is a begged MFC code for multiple windowless video renderers. MFC project, two independent video renderers hosted by the same parent window (actually through owned controls but this makes no major difference), VMR9 in windowless mode. (this expects C:\Windows\clock.avi file to be available which is no longer the case after Windows XP – simply…
A simple question being asked all over again. Given IBasicVideo, IBasicVideo2, IVMRWindowlessControl or IVMRWindowlessControl9, how to save image to file? It is easy. It is a bit easier with IBasicVideo because it is possible to query this interface directly from graph’s interface, such as IGraphBuilder, and the call will be forwarded to video renderer. This…
