When it comes to vendor specific SDK for hardware assisted video encoding, Intel Media SDK is perhaps the oldest one among current vendors: Intel, NVIDIA, AMD. And also surprisingly the worst one. All three vendors are offering their SDKs for really close capabilities, however the kits are designed and structured differently. If NVIDIA and AMD…
Another example how Microsoft Media Foundation can be annoying in small things. So we have this Video Processor MFT transform which addresses multiple video conversion tasks: The video processor MFT is a Microsoft Media Foundation transform (MFT) that performs colorspace conversion, video resizing, deinterlacing, frame rate conversion, rotation, cropping, spatial left and right view unpacking,…
New platform, Universal Windows Platform (UWP), offers new Media Foundation bugs. UWP Media Element embeds a Media Foundation video renderer to present media video frames played back. Under certain conditions, the Media Element control fails to present video inline with just incrementing the presentation time indicating playback in progress. Nevertheless once expanded full screen the…
Not the first, not the last. A Direct3D 11 enabled Media Foundation transfer fails to transfer sample attributes while doing the conversion. Why attributes are important in first place? Because we can associate data with samples/frames and have them passed through attached to specific frame as the conversion goes and as the data transits through…
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). Second, the video media source is now Direct3D 11 aware. That is, when it participates…
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));…
