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…
IDirectSoundNotify8 is an interface to get notified on playback on capture audio buffer reaching certain position in the buffer. It is a must thing when implementing ring buffers with new data continuously added to the buffer for seamless playback (continuously copied from in case of capture). This project is a minimalistic C++ sample code to…
Started as Is it possible to use local component in DLL? on microsoft.public.vc.atl newsgroup. The question is to embed a custom DirectX Media Object (DMO) into executable so that it is only available to proprietary application and not to entire system and could be reused in other applications.

Although I personally have no experience with tricky DirectShow filters that decide on possibility of connection not only looking at media type and other capabilities, there has been a number of cases mentioned that certain video decoders will only connect to renderers or video renderers in order to avoid interception of decoded data. It was…
WinHttpCrackUrl and WinHttpCreateUrl API functions are breaking URL string into components and recompose back to string. There was a mess with passwords and security issues since when putting password into URL is no more acceptable. Experienced users might remember the times when URL could embed password, e.g. ftp://john:mysecretpassword@host.com/path. Password is lo longer accepted by major…
This continues the topic raised by previous post. As fairly noticed by The March Hare, video renderer is using hardware overlay and the benchmark is incorrect if we are to extrapolate the performance to scenario with multiple video renderers. So, an updated test application creates 16 video renderers with 16 threads pumping two meida samples…
Started here: How can I overlay timestamp on the image? on microsoft.public.win32.programmer.directx.video Let us see if RGB conversion adds any noticeable effect on streaming YUY2 video, typical output of video decompressor. As a reference I am taking a simple YUY2 source -> Video Mixing Render Filter (VMR) graph, where source filter streams the same pre-allocated…
