Provided that there already is a JPEG Multi File Source Filter that can act as a video source streaming video from local JPEG files, it looked to be useful to build a virtual camera on top of this filter. This is the main difference: an existing filter is generic and customizable: it requires to be…
I decided to gather DirectShow code and filters related to processing video from network/IP cameras and video servers into a library (in fact, a few libraries) so that it could be easily used for testing, research and other purposes. As time is going to permit, documentation and sample code will be provided, further development will…
A picture for relaxation: It is probably a fresh bug there as it seems to be happening far more frequently with version 2008 (with ot without SP1) as compared to 2005. Luckily it has no effect to code being written, the problem clearly relates to debugger. At some point there is a crash, though which…
I am sharing a couple of utilities to be able to quick check system settings. TimeZoneInformation prints in a human friendly style TIME_ZONE_INFORMATION structure as reported by Windows through GetTimeZoneInformation API.

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…

I wondered if there has been any improvement with a Visual Studio .NET 2008 SP1. latest compiler from Microsoft and briefly – the result is…
Microsoft C++ compiler offers a buffer security check option since quite a long ago. It adds so called “security cookies” onto stack and checks them to be not modified by code in order to early-detect stack buffer overflow conditions. The compiler option /GS is enabled by default in Release configurations and is not applicable to…
