These include the +libsamplerate (for core libraries) and bluez (for the bluetooth proximity helper +program) libraries, although others may also be included in the future. If +PulseAudio is compiled with these optional components, this effectively +downgrades the license of the server part to GPL (see file GPL for details), +exercising section 3 of the LGPL. In such circumstances, you should treat the +client library (libpulse) of PulseAudio as being LGPL licensed and the server +part (libpulsecore) as being GPL licensed. Since the PulseAudio daemon, tests, +various utilities/helpers and the modules link to libpulsecore and/or the +afore mentioned optional GPL dependencies they are of course also GPL licensed +also in this scenario. Andre Adrian's echo cancellation implementation is licensed under a less restrictive license - see src/modules/echo-cancel/adrian-license.txt for details. --- Lennart Poettering, April 20th, 2006. +Some other files pulled into PA source (i.e. reference implementations that are +considered too small and stable to be considered as an external library) use the +more permissive MIT license. This include the device reservation DBus protocol +and realtime kit implementations. + +Additionally, a more permissive Sun license is used for code that performs +u-law, A-law and linear PCM conversions. + +While we attempt to provide a summary here, it is the ultimate responsibility of +the packager to ensure the components they use in their build of PulseAudio +meets their license requirements. |
