An interesting Media Foundation question on StackOverflow: Weird connection between CoInitializeSecurity() and Media Foundation Encoders A developer has reasons to discard standard COM security and go RPC_C_IMP_LEVEL_ANONYMOUS. Surprisingly this has effect on Windows Media Foundation API in the part of available codecs (Media Foundation Transforms). Sample code: CoInitializeSecurity line in the code above removes the…
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…
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…
A few nice updates today for a Direct3D 11 shadertoy rendering tool I posted earlier on here. As a load tool, it benefits from some flexibility and it is also a demonstration of hardware capabilities as well. First of all, the -EnumerateAdapters switch is now more verbose about DXGI and prints more of flags, e.g.:…
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
