+Most files in Libav are under the GNU Lesser General Public License version 2.1
+or later (LGPL v2.1+). Read the file COPYING.LGPLv2.1 for details. Some other
+files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to
+Libav.
+
+Some optional parts of Libav are licensed under the GNU General Public License
+version 2 or later (GPL v2+). See the file COPYING.GPLv2 for details. None of
+these parts are used by default, you have to explicitly pass --enable-gpl to
+configure to activate them. In this case, Libav's license changes to GPL v2+.
+
+Specifically, the GPL parts of Libav are
+
+- libpostproc
+- optional x86 optimizations in the files
+  libavcodec/x86/idct_mmx.c
+- the X11 grabber in libavdevice/x11grab.c
