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

This is not really obvious: Windows Media Player refuses to open a Windows Media (ASF) file with an undescriptive error message: “Windows Media Player encountered a problem while playing the file”. The problem, however, is that the file is actually good, more or less. The file plays well in DirectShow and Media Foundation APIs. There…
To follow up previous post with Media Foundation bug, here goes another one related to property handler for MPEG-4 files (.MP4) and specific property PKEY_Video_FrameRate which reports frame rate for given media file. This is the object responsible for filling columns in explorer, or otherwise visually the bug might look like this: The values of the properties are…
Unfortunately, 64-bit version of Windows Media Video 9 Decoder is not as good as its 32-bit sister. 32-bit version is user an order of magnitude more frequently and does not give troubles, nevertheless 64-bit version offers similar feature set it is pretty hard to see it in action since it takes a 64-bit media application to host…
