Open source

The app ships VLCKit 3.6.0 on libVLC 3.0.21, built from VideoLAN's source with eight patches. Three leave out the code that is under the GPL rather than the LGPL: zvbi, seven of libVLC's modules, and the yadif deinterlacing modes. The rest only let VideoLAN's build run with today's tools; two of them change one line each of zlib's and libpng's source, so those two libraries are altered versions. Everything else in the binary is VideoLAN's build, under the LGPL 2.1 or more permissive licences.

The patches, the scripts, the README and the licence texts below, in one archive.

The build starts from these, at the exact revisions it pins:

• VLCKit 3.6.0

  Tag 3.6.0, commit c73b779f.

• libVLC 3.0.21

  vlc's 3.0.21 tag, commit dd8bfdba, which VLCKit 3.6.0 pins.

VLCKit's build applies its own 49 patches to libVLC and compiles every library libVLC links from source, downloading each from its own host. If a host no longer has a tarball the build needs, write to us and we will send it.

Applied to VLCKit at its 3.6.0 tag, in order, on a branch the build script makes.
