Libraries

The following table shows the types of the libraries created by FFmpegKit build scripts and published in the FFmpegKit releases.

Note that on Apple platforms the primary bundle format is xcframeworks/frameworks. Library types listed below are used to create them. Additionally, Supplementary Libraries are libraries that are required to build External Libraries.

	FFmpegKit		FFmpeg		External Libraries	Supplementary Libraries
Android	shared (.so)		shared (.so)		static (.a)	static (.a)
Apple (iOS, macOS, tvOS)	>= v4.5.1	shared (.dylib)	>= v4.5.1	shared (.dylib)	static (.a)	static (.a)
	< v4.5.1	static (.a)	< v4.5.1	static (.a)
Linux	shared (.so)		shared (.so)		static (.a)	static (.a)

Below you can see how they are linked.

	FFmpegKit		FFmpeg		External Libraries	Supplementary Libraries
Android	Dynamically linked to FFmpeg		Statically linked to External Libraries		Statically linked to Supplementary Libraries	-
Apple (iOS, macOS, tvOS)	>= v4.5.1	Dynamically linked to FFmpeg	>= v4.5.1	Dynamically linked to External Libraries	Statically linked to Supplementary Libraries	-
	< v4.5.1	Statically linked to FFmpeg	< v4.5.1	Statically linked to External Libraries
Linux	Dynamically linked to FFmpeg		Statically linked to External Libraries		Statically linked to Supplementary Libraries	-

And, the following table shows the library files included in FFmpegKit bundles.

Notice that when FFmpeg is built as shared libraries, External Libraries are not put inside the bundles since they are statically linked and their object code is already inside the FFmpeg libraries.

	FFmpegKit	FFmpeg	External Libraries		Supplementary Libraries
Android	X	X	-		-
Apple (iOS, macOS, tvOS)	X	X	>= v4.5.1	-	-
