OSWrapper

Single-header file libraries to wrap OS-specific functionality.

Library	Description	Platform implementations
oswrapper_image.h	Image decoder using OS libraries	macOS, Windows (Vista and higher), Emscripten
oswrapper_audio.h	Audio decoder using OS libraries	macOS (10.4 and higher), Windows (7 and higher)
oswrapper_audio_enc.h	Audio encoder using OS libraries	macOS (10.4 and higher), Windows (7 and higher)

Usage

These libraries are single-header file libraries. Include them in exactly one C or C++ file as such:

#define OSWRAPPER_LIBRARYNAME_IMPLEMENTATION
#include "oswrapper_libraryname.h"

Replace libraryname with the name of the library.

Unlike standard single-header file libraries, you'll generally need to link against a system library to use these libraries, or perform some platform-specific initialisation action before using them. Here's the requirements:

Library	macOS	Windows	Emscripten
oswrapper_image.h	Link with -framework AppKit	Initialise the COM library, link with windowscodecs.lib	Compile with Asyncify
oswrapper_audio.h	Link with -framework AudioToolbox	Initialise the COM library, link with mfplat.lib, mfreadwrite.lib, and shlwapi.lib	N/A
oswrapper_audio_enc.h	Link with -framework AudioToolbox	Initialise the COM library, link with mf.lib, mfplat.lib, mfreadwrite.lib, and shlwapi.lib	N/A

Full examples of linking and using OSWrapper libraries can be found in the test folder.

Future work

• Emscripten audio decoding
• Haiku support
• SerenityOS support

Issues and PRs are welcome.
