The dev kit contains a C++ header file named effects.h that contains 2 interfaces that must be implemented to get the plugin to work with WMP. This sample registers and works without issues in WMP. I downloaded the Latest Windows SDK which contains a C++ plugin wizard to compile a working visualization sample. In a nutshell: WMP will call certain methods on my C# COM interface, but not others. I have persisted with this for 3 days (about 20 hours) and not got past the single issue I will describe below.įor those who don't know, WMP visualizations are the pretty images that show in media player while listening to music. I am quite new to exposing C# to COM and may have missed something basic. If visualizations are not displayed, check if the file you playback is a MIDI file or not.įor further details, please refer to the following solution in Microsoft's technical support website.I am attempting to create a Windows Media Player (WMP) Visualization plugin in C#. Since MIDI files contain only descriptive information about music and does not include actual sound data, visualizations are not displayed.
