One more system check tool to quickly enumerate available monitors (using DXGI), take snapshots and was them in PNG files (using WIC). Apart from straightforward desktop snapshot taking, the tool offers a few more functions: Goes through the entire list of available video adapters and connected monitors Uses three slightly different methods to do the…
Just a small test here to feature use of multiple GPUs within single Media Foundation pipeline. The initial idea here is pretty simple: quite so many systems are equipped with multiple GPUs, some have “free” onboard Intel GPU idling in presence of regular video card. Some other systems have integrated “iGPU” and discrete “dGPU” seamlessly…
One annoying thing existing for a long time is an internal _com_error exception in Direct3D shader cache, coming from D3DSCache.dll during execution of innocent API calls like D3D11CreateDevice. Also related storage location for the cache files is %LOCALAPPDATA%\D3DSCache, one can try deleting it completely in the case annoying issue persists. Many of us can afford…
Microsoft Windows operating systems come with built-in API for face tracking in Windows.Media.FaceAnalysis Namespace. It is available since Windows 10 “Threshold 1” build 1507 even though it is probably not the most popular API for a few reasons but maybe most important is that like some other new additions, the API addresses UWP development. Nonetheless,…
There is a number of systems out there equipped with multiple GPUs which work cooperatively. The technology itself started from Integrated graphics processing units which brought a “free” GPU into system. Such system equipped with an additional discrete card obtained two GPUs at a time and from certain point it was a challenge to not…
A few nice updates today for a Direct3D 11 shadertoy rendering tool I posted earlier on here. As a load tool, it benefits from some flexibility and it is also a demonstration of hardware capabilities as well. First of all, the -EnumerateAdapters switch is now more verbose about DXGI and prints more of flags, e.g.:…
ID3D11VideoContext::VideoProcessorSetOutputTargetRect method: The target rectangle is the area within the destination surface where the output will be drawn. The target rectangle is given in pixel coordinates, relative to the destination surface. If this method is never called, or if the Enable parameter is FALSE, the video processor writes to the entire destination surface. Okay, let…
