libbluray is the library you'll need installed to play back Blu-rays. You'll need libaacs as well to bypass the DRM.

The software ships with a couple of programs that are helpful as well. Some of them are:

  • bd_splice which you can use to copy pieces of titles / playlists (see also bluray_copy for same functionality)
  • bd_list_titles to display title information
  • bd_info to display information about the Blu-ray
