MilkDrop 2 Visualization Component for foobar2000

Port of Winamp's MilkDrop 2 visualization library from its original DirectX 9 version to use DirectX 11.1. MilkDrop 2 takes you flying through visualizations of the soundwaves you're hearing, and uses beat detection to trigger myriad psychedelic effects, creating a rich visual journey through sound.

Prerequisites to build the foo_vis_milk2.dll component for foobar2000:

• foobar2000 SDK: download the latest version and uncompress the contents in the external/ folder and apply the patch.
• NS-EEL2 (included in WDL): the files required to build the DLL are included in this repository.
• projectM EEL: clone the repository into the external/ folder, checkout the HEAD of the master branch and apply the patch. This is the default expression evaluation library.
• DirectXTK: the files required to build the DLL are fetched via the NuGet package manager.
• Windows Template Library (WTL): the files required to build the DLL are fetched via the NuGet package manager.
• Visual Studio 2022: open the foo_vis_milk2 solution, set foo_vis_milk2 as the Startup Project, install WTL and DirectXTK as NuGet packages, select a configuration, and build the solution.

Import the Visual Studio installation configuration file to install required components such as the Windows SDK, Active Template Library (ATL) and NuGet Package Manager.

Refer to the build pipeline jobs for a step-by-step guide on how to build. Only x86 and x64 Intel architecture platforms are tested.

See CHANGELOG for additional details.

See BUILDING for solution build instructions.

See TESTING for an outline of how to run a simple unit test and collect runtime coverage.

See LICENSES to become thoroughly confused.

Features

• Uses DirectX 11.1 (Direct3D 11.1, DXGI 1.6, Direct2D 1.1, DirectWrite 1.1) for rendering.
• Supports the Default User Interface (Default UI) only.
• Configurable through foobar2000 preferences instead of .ini files.
• Can build 32-bit and 64-bit x86 component configurations as well as ARM64 and ARM64EC.
• Built for foobar2000 2.0 and later with latest Windows 11 SDK (10.0.26100.0) and MSVC (v143).
• Updated all library dependencies to their latest available releases.
• Deprecated or insecure functions have been rewritten and most unused functionality removed.
• vis_milk2 has been upgraded to use more modern C++ alongside the move to DirectX 11.
• Tested on foobar2000 v2.1.6 (x86 32-bit and x86 64-bit) and Microsoft Windows 11 (Build 26100.1742).
• Intel architecture versions support Windows 7 SP1 or later and ARM architecture versions support Windows 10 or later.
  • However, some features such as hybrid graphics, high DPI displays and HDR might not work if the DXGI version required to support them is not on the system.

Run Requirements and Installation

• Download foobar2000 and install.
• Import foo_vis_milk2.fbk2-component into foobar2000 using the File > Preferences > Components > Install... menu item.
• Download and extract presets into this component's directory of foobar2000. This should be <foobar2000 profile folder>\milkdrop2\presets.
• Textures can also be added to <foobar2000 profile folder>\milkdrop2\textures and referenced in their accompanying configuration file <foobar2000 profile folder>\milkdrop2\milk2_img.ini.
• Custom messages can be entered into <foobar2000 profile folder>\milkdrop2\milk2_msg.ini.

Presets

The preset files define the visualizations via pixel shaders, equations and parameters.

The foobar2000 component is not packaged with any presets. Some presets enjoyed by Ryan Geiss (the MilkDrop 2 author) can be downloaded from his website. In addition, the projectM repository archives several preset and texture collections:

• Cream of the Crop Pack: A collection of about 10,000 presets compiled by Jason Fletcher.
• Base Milkdrop Texture Pack: Recommended for use with any preset pack!
• Milkdrop 2 Presets: The original preset collection shipped with Milkdrop and Winamp.

Build Notes

• Removed /d2notypeopt Visual C++ compiler option as it is applied by default on Visual Studio 2019 version 16.6 and later. (1, 2)
• Built all targets using v143 Platform Toolset for as /arch being "Not set" should default to /arch:SSE2 on Visual Studio 2022 version 17.10 and later. (1, 2)

MilkDrop 2

MilkDrop 2 (vis_milk2) is a music visualizer - a "plug-in" to the Winamp music player. The changes to the MilkDrop 2 source code release from 5/13/13 (version 2.25c) include:

• Porting VMS from DirectX 9 to Direct X 11.1. DirectX 11.1 is Direct3D 11.1, DXGI 1.6, Direct2D 1.1, and DirectWrite 1.1.
• Porting text layout and rendering from D3DX9 and GDI to DirectWrite and Direct2D, respectively.
• Building DLL with Visual Studio 2022 (v143) Platform Toolset.
• Minor bug and typo fixing so that the plug-in can be used in Winamp and foobar2000 music players without crashing.
• Fixing of string resources to flow consistently with Segoe UI spacing and sizing.
• Minor cleaning and updating of configuration panel to match functioning features and UI modifications.
• Developer experience improvements, such as:
  • Updated dependencies to latest available versions.
  • Refactored EEL2 and DirectXTK into separate projects.
  • PCH and multiprocessor compile enabled for fast builds.
  • Buildable with C++20 compiler, including the address sanitizer and fuzzer. Builds clean using /W4 (level 1,2,3,4 compiler warnings) and /WX (treat compiler warnings as errors) build options.
  • All character string and memory manipulation functions migrated to use their respective secure CRT versions.
  • Several utility functions and container classes replaced with their STL equivalents.
  • Enabled and added x86 and ARM 64-bit builds (x64, ARM64 and ARM64EC platforms) in addition to the upgraded x86 32-bit (Win32 platform) one. The 64-bit DLLs are not as extensively tested since most music players are still 32-bit applications.
  • Added a minimal unit test with associated infrastructure and some API service mock classes to test DLL initialization.
  • Added CI pipeline (GitHub Actions).
  • Enforced more consistent formatting (with ClangFormat), line endings, and file encodings. Important notes:
    • *.rc encoding was kept as "Western European (Windows) - Codepage 1252".
    • *.vcxproj/*.sln encoding was kept as "Unicode (UTF-8 with signature/BOM) - Codepage 65001".
    • All other text files use "Unicode (UTF-8 without signature) - Codepage 65001". All text files use CRLF line endings.
  • Updated comments and consolidated documentation.
