Further experiments with Direct3D 11 shadertoy rendering: HTTP Server API integration and serving on demand parts of HTTP Live Streaming (HLS) asset using Media Foundation with hardware video encoding. An hls.js player is capable to read and play the content, including being able to step between quality levels. A sort of a Google Stadia for…
If there was a prize for the messiest SDK, Intel Media SDK would be a favorite. They seem to have put but special care to make things confusing, unclear, inconvenient to use and sick perplexed. So there is no clear signal which versions of SDK have support for SkipFrame field. One has to query and…
I am sharing today one another tool which I am using to simulate load from time to time (such as the one against video/desktop streaming through Rainway). The application is rendering an HLSL variant of Sakura Bliss shadertoy (by Philippe Desgranges) using Direct3D 11 swap chain in DXGI_SWAP_EFFECT_FLIP_DISCARD mode. For starters, the shader is mesmerizing…
Fancy stuff goes first: This is an application that renders this shadertoy by Taron into a video file with requested metrics. Why? it looks great it is a source of content used for various development and testing purposes

MPEG-4 Media Foundation Source stubbornly keeps marking a second video sample with a MFSampleExtension_CleanPoint flag even though nothing suggests that the video frame is an IDR frame. The actual video frame is a P frame both in terms of MP4 box formatting and contained NAL units (the video is in fact an “infinite GOP” flavor…
A bump of StackOverflow post about Media Foundation design flaw related to video encoding. Set attributes via ICodecAPI for a H.264 IMFSinkWriter Encoder I am trying to tweak the attributes of the H.264 encoder created via ActivateObject() by retrieving the ICodecAPI interface to it. Although I do not get errors, my settings are not taken…
