Addition of another crazy thing into internal tooling uncovered new interesting bug. 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…
Isolated property is supposed to enable referencing in-process COM servers as a registration free COM dependency, but something got broken on the way: Visual Studio 2019 Preview and .NET 5 produce applications that lose the link. It is still preview so hopefully things get resolved timely. The issue on GitHub: Single-File Executable Cannot Use Registration…

I was under impression that AMD hardware allows just one video encoding session and prevents from having multiple side by side. This has been the consistent behavior I was seeing and I was always wondering why it had to be that tight. To my surprise, the actual limitation is higher and, in particular, is sixteen…
