The core parts of AAC were patented back in 1998. Those patents have expired. Some of the newer AAC features involved with HE-AAC are still patented. These patches are taken from fedora where they remove all patented functionality. Note that LC-AAC comprises the majority of AAC content. HE-AAC is for low bitrate stuff like audiobooks. Patches come from Fedora where this is also distributed. Local compiles show a 40% size reduction in the final ipk. Signed-off-by: Rosen Penev <rosenp@gmail.com> |
