The licensing is explained here: https://git.alsa-project.org/?p=alsa-plugins.git;a=blob;f=rate/rate_samplerate.c So this particluar rate plugin is licensed under GPL 2.0 "to follow the license of libsamplerate", unless you have a commercial license to libsamplerate. I don't think the rationale for that exception makes much sense (LGPL would have worked just fine, as far as I can tell), but at this point relicensing may be very difficult due to many contributors. libsamplerate was relicensed under the 2-clause BSD license in 2016[1], which may or may not allow you to apply LGPL to the rate plugin (my guess would be that it doesn't allow you to do that, but IANAL).

I now had a look at the link you provided, and there I saw that BSD-3- Clause and MIT were also mentioned. I had a closer look at the code, and I found two more exceptions: the libspeexdsp based rate plugin (under the pph directory) seems to be licensed under BSD-3-Clause, and rate-lav/gcd.h is licensed under MIT (rate-lav/rate_lavrate.c is LGPL, however). > The licensing is explained here: > > https://git.alsa-project.org/?p=alsa-plugins.git;a=blob;f=rate/rate_samplerate.c > > So this particluar rate plugin is licensed under GPL 2.0 "to follow the > license of libsamplerate", unless you have a commercial license to > libsamplerate.

Relicensing shouldn't be that hard after all, if that's desired (I think it would be a good idea). Now that I looked, there actually aren't many contributors to that plugin, only Takashi and Jaroslav. Diego E. 'Flameeyes' Pettenò also has a commit, but it only changes one line in the build system. > libsamplerate was relicensed under the 2-clause BSD license in 2016[1], > which may or may not allow you to apply LGPL to the rate plugin (my > guess would be that it doesn't allow you to do that, but IANAL). > > [1] http://www.mega-nerd.com/SRC/license.html -- Tanu https://www.patreon.com/tanuk https://liberapay.com/tanuk _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org https://mailman.alsa-project.org/mailman/listinfo/alsa-devel ^ permalink raw reply [flat|nested] 7+ messages in thread

But the only concern is that no one but for lawyers can confirm its validity... thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org https://mailman.alsa-project.org/mailman/listinfo/alsa-devel ^ permalink raw reply [flat|nested] 7+ messages in thread

You don't need to care, except if you do use open source code in distributed closed source programs (aka windows and macos). -- Sylvain ^ permalink raw reply [flat|nested] 7+ messages in thread
