Provides builds of libmpv for macOS & iOS, used by media_kit, compatible with commercial use for playback, and GPL use for encoding.

Heavily inspired by Homebrew and IINA.

Notes

Some dependencies, which are not needed at the moment, may be added in the future:
- libbluray: A library for reading and parsing Blu-ray discs, with support for advanced features such as BD-J menus and seamless branching
- libarchive: A library for reading various archive formats, including tar and zip, with support for compression and metadata, and a flexible API for reading and extracting archive contents
We use meson as much as possible in order to simplify cross-compilation, at the cost of some heaviness regarding legacy packages
If the build freezes, reboot macOS

Command to visualize the workflow of a Makefile:

$ make -Bnd | make2graph | dot -Grankdir=LR -Tpng -o graph.png

How the libass optional patch was created

As the dependency of mpv on libass is deeply embedded in the code, the simplest solution was to:

Remove the dynamic linking in meson.build.
Include the ass/ass.h and ass/ass_types.h headers directly in the code
Remove the call to ass_library_version in player/command.c
Remove the calls to ass_library_init, called by mp_ass_init, in sub/osd_libass.c and sub/sd_ass.c
