The project root includes nine directories, five top-level build scripts (nix-android.sh, nix-ios.sh, nix-linux.sh, nix-macos.sh and nix-tvos.sh), one combining script (nix-apple.sh) for Apple platforms, one LICENSE file and three markdown files (README.md, CONTRIBUTING.md and CODE_OF_CONDUCT.md).

• The android folder contains the files necessary to build the FFmpegKitNext Android library. These files are:

  • Configuration files required by gradle
  • A documentation configuration file for doxygen
  • The library source code inside the ffmpeg-kit-next-android-lib folder
  • NDK build files under the jni folder
  • A README.md file

• The apple directory includes the files necessary to build the FFmpegKitNext Objective-C library for iOS, macOS and tvOS. They are:

  • Configuration files required by Autotools
  • A documentation configuration for doxygen
  • The library source code inside the src folder
  • A README.md file

• The docs folder contains the documentation and digital assets.

• The flutter folder contains the files of the flutter plugin, which supports the Android, iOS and macOS platforms.

• The linux directory includes the files necessary to build the FFmpegKitNext C++ library for Linux. These files are:

  • Configuration files required by Autotools
  • A documentation configuration for doxygen
  • The library source code inside the src folder
  • A README.md file

• The react-native folder contains the files of the react-native plugin, which supports the Android and iOS platforms.

• The scripts directory includes all the scripts called by the top-level build scripts.

  • Scripts responsible for cross-compiling external libraries are grouped by platform name and can be found under the android, apple and linux folders
  • The function scripts contain platform-specific bash functions
  • The main scripts are responsible for building an architecture for a platform
  • The run scripts execute the cross-compilation scripts under the android, apple and linux folders
  • The start scripts (start-android.sh, start-ios.sh, start-linux.sh, start-macos.sh, start-tvos.sh and start-apple.sh) are the per-platform build entry points. The top-level nix-<platform>.sh wrappers only prepare a Nix environment and then invoke them, so these scripts can be run directly to build without Nix, as long as the required toolchain is already available on the system
  • The source.sh script contains external library repository URLs and their versions
  • The variable.sh script includes common variables used by all platforms

• The src directory is empty by default. The source code of the enabled external libraries is downloaded into this directory by the top-level build scripts.

• The tools directory includes patch files and release scripts.

• A temporary folder named .tmp is created at the start of the build to store temporary files needed by the scripts, such as the gas-preprocessor.pl script and the gnu-config project.

• After compilation, all compiled objects (libraries, frameworks, xcframeworks, Android archives, etc.) are created as bundles under the prebuilt directory.

  • The Android archive (.aar) in local Maven format is located under the bundle-android-aar-${API}-maven folder
  • The iOS frameworks are located under the bundle-apple-framework-ios-${IOS_MIN_VERSION} folder
  • The iOS xcframework is located under the bundle-apple-xcframework-ios-${IOS_MIN_VERSION} folder
  • The macOS frameworks are located under the bundle-apple-framework-macos-${MACOS_MIN_VERSION} folder
  • The macOS xcframework is located under the bundle-apple-xcframework-macos-${MACOS_MIN_VERSION} folder
  • The tvOS frameworks are located under the bundle-apple-framework-tvos-${TVOS_MIN_VERSION} folder
  • The tvOS xcframework is located under the bundle-apple-xcframework-tvos-${TVOS_MIN_VERSION} folder
  • The Linux headers and libraries are located under the bundle-linux folder
