•The BPG decoding library uses a modified version of FFmpeg released under the LGPL version 2.1 as HEVC decoder. The BPG decoding library excluding the FFmpeg code is released under the BSD license. 
•The BPG encoder is released under the BSD license. It optionally uses the JCTVC HEVC reference encoder which is also released under the BSD license or the x265 library released under the GPL license. 
•Some of the HEVC algorithms may be protected by patents in some countries (read the FFmpeg Patent Mini-FAQ for more information). Most devices already include or will include hardware HEVC support, so we suggest to use it if patents are an issue.
