Just a small tool here to try a few of a popular resolutions and measure video encoding latency. The encoder is running in configuration to address needs of real-time encoding with speed over quality setup. Note that the performance might be affected by side load, such as graphics application (I often use this application for…
It is embarrassing, my friends…
Microsoft Windows operating systems come with built-in API for face tracking in Windows.Media.FaceAnalysis Namespace. It is available since Windows 10 “Threshold 1” build 1507 even though it is probably not the most popular API for a few reasons but maybe most important is that like some other new additions, the API addresses UWP development. Nonetheless,…
Comparison of time codes is one method, and getting impression on latency through driving is another. Rainway Xbox One UWP application as a thin client to a desktop PC game. And we are happy people love it: Whoever the engineers who wrote the core technology, the minimal-latency streaming code – wow, I am so impressed…
In continuation of previous post about C++/WinRT and Telegram, here we with @ParameterSetAnalyzeBot: “Your buddy to extract H.264 parameter set NAL data”. In a chat, it expects an MP4 file with an H.264 video track sent him (her?). Then it extracts data from sample description box and deciphers into readable form: It’s literally taking the…
The previous post was focusing on problems with the hardware MFT decoder provided as a part of video driver package. This time I am going to mention some data about how the inefficiency affects performance of video capture using a high frame rate 260 FPS camera as a test stand. Apparently the effect is better…
Video GPU vendors (AMD, Intel, NVIDIA) ship their hardware with drivers, which in turn provide hardware-assisted decoder for JPEG (also known as MJPG and MJPEG. and Motion JPEG) video in form-factor of a Media Foundation Transform (MFT). JPEG is not included in DirectX Video Acceleration (DXVA) 2.0 specification, however hardware carries implementation for the decoder.…
