SUMMARY = "Sound server for Linux and Unix-like operating systems"
DESCRIPTION = "A general purpose sound server intended to run as a middleware \
between your applications and your hardware devices, either using ALSA or OSS."
HOMEPAGE = "http://www.pulseaudio.org"
SECTION = "libs/multimedia"

# Most of PulseAudio code is under LGPL-2.1-or-later. There are a few
# exceptions:
#
# The "adrian" echo canceller variant has code under a non-standard permissive
# license. See src/modules/echo-cancel/adrian-license.txt for details. This
# recipe disables the adrian echo canceller to avoid hassle with the unusual
# license.
#
# The src/modules/reserve* and src/pulsecore/rtkit* files are under the MIT
# license.
#
# The src/pulsecore/filter/ directory contains code under the 3-clause BSD
# license.
#
# People who distribute PulseAudio binaries need to also consider that there
# are some dependencies to GPL libraries. LGPL code that depends on GPL
# libraries probably becomes effectively GPL-licensed (at compile-time? or at
# at link-time?). I'm not a lawyer, though, so I'm not sure of the exact
# implications. The GPL dependencies only affect the server, not the client
# library, with the exception of libdbus that affects both. These are the GPL
# library dependencies:
#
# One of the resampler implementations uses libsamplerate. This recipe doesn't
# enable that resampler, however.
#
# One of the database implementations uses gdbm. This recipe doesn't enable
# that database implementation, however.
#
# module-lirc (enabled by PACKAGECONFIG[lirc]) uses LIRC.
#
# module-equalizer-sink uses FFTW. This recipe disables that, however.
#
# The dependency with the most complicated licensing considerations is libdbus.
# When PACKAGECONFIG[dbus] is enabled (like it is by default), libdbus will be
# used by both the server and the client library (libpulse). Does this affect
# applications that use libpulse? It should also be noted that libdbus is
# dual-licensed: either GPL-2.0-or-later or AFL-2.0 terms apply. Whose decision
# is it which of the licenses apply? What a mess. Some people hold the view that
# libdbus is a system library that is covered by the "special exception" in
# GPLv2's section 3, and therefore libdbus's GPL license doesn't affect
# PulseAudio.
