Libraries

The following table shows the types of libraries distributed in FFmpegKitNext bundles.

Notes:

1. On Apple platforms, the primary distribution formats are xcframeworks and frameworks. The library types listed below are used to create these bundles
2. On Linux, FFmpeg is linked against two sets of External Libraries. The first consists of static libraries downloaded and built by the FFmpegKitNext build scripts. The second consists of shared libraries installed manually on the host system. The table below shows only the former
3. Supplementary Libraries are dependencies required to build External Libraries
4. On Web, dynamic linkage builds load FFmpeg side modules at runtime. Static linkage builds link FFmpeg libraries into one main WebAssembly module

	FFmpegKit	FFmpeg	External Libraries	Supplementary Libraries
Android	shared (.so)	shared (.so)	static (.a)	static (.a)
Apple (iOS, macOS, iPadOS, tvOS, visionOS)	shared (.dylib)	shared (.dylib)	static (.a)	static (.a)
Linux	shared (.so)	shared (.so)	static (.a)	static (.a)
Web	WebAssembly (.wasm), JavaScript (.js) and shared (.so) (if dynamically linked)	WebAssembly side modules (.so) (when dynamically linked) or linked into the main module (when statically linked)	static (.a)	static (.a)

The following table shows how these libraries are linked.

The following table shows the library files included in FFmpegKitNext bundles.

On Linux, some libraries are statically linked into FFmpeg, while others are dynamically linked from the host system. Therefore, they are also not included in FFmpegKitNext bundles.
