IMSDroid is a free software licensed under the GNU GPLv3 license terms. As far as the commercial product using IMSDroid or doubango isn't a closed-source software and is compatible with GNU GPL terms, there is no license violation. However, if your commercial product is a closed-source software and you want to keep it closed, then you should get a non-GPL license.
We can provide a non-GPL version of all components used in both IMSDroid and doubango except for x264 library.
~~An alternative to x264 could be PacketVideo's H.264 implementation which is released under Apache License.~~Starting Doubango 1220 we support OpenH264 (BSD).
Owners of doubango licenses can reuse part or whole
IMSDroid source code without any restriction.
