In continuation of previous AMD AMF encoder latency at faster settings posts, side by side comparison to NVIDIA encoders. The numbers are to show how different they are even though they are doing something similar. The NVIDIA cards are not high end: GTX 1650 is literally the cheapest stuff among Turing 16xx series, and GeForce…
A few weeks ago I posted a problem with AMF SDK about a property included into enumeration and triggering a failure in a followup request for value. It appeared to be “internal property” to intentionally tease the caller and report error by design, unlike all other dozens of SDK properties. And of course to raise…
It appears that re-initialization of encoding session with NVIDIA Video Codec SDK is or might be producing an unexpected memory leak. So, how does it work exactly? The root case problem is secondary nvEncInitializeEncoder call. Alright, it might be not exactly how API is designed to work, but returned statuses all indicate success, so it…
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));…
