Herqq libraries are open source
HUPnP core library
As of 25th of June 2010 and starting with the HUPnP version 0.6.0, the HUPnP core library is distributed under the LGPLv3 license.
Previous HUPnP releases were licensed under the GPLv3 only. In addition, it is important to note that a test program called HUpnpSimpleTestApp provided with the HUPnP library is still licensed under the GPLv3 only.
HUPnPAv was initially released in 17th of April 2011 and since then it has been distributed under the GPLv3 only. Similarly, the HUpnpAvSimpleTestApp provided with the HUPnPAv library is licensed under the GPLv3 only. It is possible that a future version of HUPnPAv will be released under other licenses as well. This is under consideration.
