Being complicated for many things, Media Foundation is still quite simple for the basics. To capture video with Media Foundation the API offers Source Reader API which uses Media Foundation primitives to build a pipeline that manages origin of the data (not necessarily a live source as in this example, but can also be a…
A few updates to DirectShowReferenceSource module, it’s Media Foundation video Media Source related part today. First, the video media source is now handling restarts from paused state correctly and resumes frame generation from proper position (not from zero as before).

For already years Nvidia’s H.264 video encoder Media Foundation Transform has been broken giving REGDB_E_CLASSNOTREG “Class not registered” failure in certain circumstances, like main display is not the one connected to Nvidia video adapter. As simple as this: CoInitialize(NULL); MFStartup(MF_VERSION); class __declspec(uuid(“{60F44560-5A20-4857-BFEF-D29773CB8040}”)) CFoo; // NVIDIA H.264 Encoder MFT CComPtr<IMFTransform> pTransform; const HRESULT nCoCreateInstanceResult = pTransform.CoCreateInstance(__uuidof(CFoo));…
If I recall correctly, Intel was the first vendor to supply H.264 hardware video encoder as a Media Foundation Transform (since Windows 7) and overall Intel Quick Sync Video (QSV) was the earliest widely available implementation of hardware assisted encoding. However one of the aspects of such encoding seems to be missing: update of encoder…

Microsoft released new Windows 10 update and again there is a new tsunami approaching. Media Foundation H.265 decoder: there is no longer “preliminary documentation” notice in MSDN article. The decoder is a substandard quality software item but it covers more or less what it has to. In particular, it indeed backs H.265 video playback including…
