All PulseAudio source files are licensed under the GNU Lesser General Public
|
|
License. (see file LGPL for details)
|
|
|
|
However, the server side has optional GPL dependencies. These include the
|
|
libsamplerate and gdbm (core libraries), LIRC (lirc module), FFTW (equalizer
|
|
module) and bluez (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 the 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.
|
|
|
|
In addition to this, if D-Bus support is enabled, the PulseAudio client library
|
|
(libpulse) MAY need to be licensed under the GPL, depending on the license
|
|
adopted for libdbus. libdbus is licensed under either of the Academic Free
|
|
License 2.1 or GPL 2.0 or above. Which of these applies is your choice, and the
|
|
result affects the licensing of libpulse and thus, potentially, all programs
|
|
that link to libpulse.
|
|
|
|
Andre Adrian's echo cancellation implementation is licensed under a less
|
|
restrictive license - see src/modules/echo-cancel/adrian-license.txt for
|
|
details.
|
|
|
|
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.
