vlc-syphon-ndi plugins for VLC 3.0.x on macOS (11 or later). NDI needs macOS 13 and only the
NDI Runtime for macOS (libNDI_for_Mac.pkg) from http://ndi.link/NDIRedistV6Apple.
NDI Tools is not needed.

Keep the three items in plugins/ together. Recommended: leave VLC.app untouched and
start VLC with the plugin folder:

  mkdir -p "$HOME/Library/Application Support/vlc-syphon-ndi"
  cp -R plugins "$HOME/Library/Application Support/vlc-syphon-ndi/"
  open --env VLC_PLUGIN_PATH="$HOME/Library/Application Support/vlc-syphon-ndi/plugins" -a VLC

Then enable the filters in Preferences > Show All > Video > Filters (Syphon, NDI) and
Audio > Filters (NDI), or: --video-filter=syphon:ndi --audio-filter=ndi
