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…

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…
Yesterday’s bug is not the only “news”. Some time ago I already saw weird broken behavior of rebuild of DirectShowSpy.dll with current version of Visual Studio and MSVC. Now the problem is getting more clear. Here is some interface: Compiled into type library it looks okay. Windows SDK 10.0.18362 COM/OLE Object Viewer shows the correct…
I might have mentioned that Intel Media SDK has a ridiculously eclectic design and is a software package for the brave. Something to stay well clear of for as long as you possibly can. To be on par on the customer support side Intel did something that caused blocking of Intel Developer Zone account. Over…
XAML MediaPlayerElement control/class is exhibiting a ridiculous bug on Xbox One: once you are going fullscreen the control is not showing the video correctly. A texture is assumed to be rendered in full and it is cropped instead (left top quarter of actual video or alike). I saw this before but at that time I…
