Interface methods lack pure specifiers. This might be OK for some development but once you try to inherit your handler class from public winrt::implements<AsyncCallback, IRtwqAsyncCallback> you are in trouble! 1>Foo.obj : error LNK2001: unresolved external symbol “public: virtual long __cdecl IRtwqAsyncCallback::GetParameters(unsigned long *,unsigned long *)” (?GetParameters@IRtwqAsyncCallback@@UEAAJPEAK0@Z) 1>Foo.obj : error LNK2001: unresolved external symbol “public: virtual…
Added a few more resolutions to NvcEncode tool. Resolutions above 4K are tried with H.264 codec but they are expected to not work since H.264 codec is limited to resolutions up to 4096 pixels in width or height. So the new ones apply to H.265/HEVC. They work pretty well on NVIDIA GeForce RTX 2060 SUPER:…
More of unusual stuff: mix of Media Foundation pipeline, with a custom media source specifically, with GStreamer pipeline. It appears that with all bulkiness of GStreamer runtime, the framework remains open for integrations and flexible for a mix of pre-built and custom components. PoC push source plugin on top of Media Foundation media session and…

An application is creating audiovisual HLS (HTTP Live Streaming – adaptive streaming developed by Apple) stream on the fly now with Microsoft PlayReady DRM encryption attached. UWP samples offer a sample application for playback: PlayReady sample. The playback looks this: Oops, no video!…
I mentioned issues in AMD’s and Intel’s video encoding related drivers, APIs and integration components. Now I switched development box video card to NVIDIA’s and immediately hit their glitch too. NVIDIA GeForce RTX 2060 SUPER offers really fast video encoder and consumer hardware from AMD and Intel is simply nowhere near. 3840×2160@144 video can be…
The small box in the right bottom corner of the video is Chuwi LarkBox “World’s Smallest 4K Mini PC”. With Intel J4115 CPU and Intel UHD Graphics 600 GPU it is running Windows 10 and is capable to render and encode video in real time. 1600×900@60 is a bit too heavy for it and VLC…
There is some support for Opus in Windows, unfortunately however it is not documented. IIRC it came to extend media codec support in Microsoft Edge browser, and since internally Microsoft Edge is using standard platform media API Media Foundation, the decoder came in format of Media Foundation Transform. It is interesting that Opus decoding was…
