IINA ships with pre-compiled dynamic libraries for convenience reasons. If you aren't planning on modifying these libraries, you can follow the instructions below to build IINA; otherwise, skip down to Building mpv manually and then run the steps here:

Using the pre-compiled libraries

  1. IINA uses CocoaPods for managing the installation of third-party libraries. If you don't already have it installed, here's how you can do so:

Using RubyGems

$ sudo gem install cocoapods

Using Homebrew

$ brew install cocoapods
  1. Run pod install in project's root directory.

  2. Open iina.xcworkspace in the latest public version of Xcode. IINA may not build if you use any other version.

Building mpv manually

  1. Install mpv:
$ brew install mpv --with-uchardet

Feel free to include your own copies of the other libraries if you'd like.

  1. Copy latest header files into libmpv/include/mpv/.

  2. Run other/parse_doc.rb. This script will fetch the latest mpv documentation and generate MPVOption.swift, MPVCommand.swift and MPVProperty.swift. This is only needed when updating libmpv. Note that if the API changes, the player source code may also need to be changed.

  3. Run other/change_lib_dependencies.rb. This script will deploy the depended libraries into libmpv/libs. Make sure you have a phase copying of all these dylibs in Xcode's build settings.
