+@section Advanced linking configuration
+
+If you compiled FFmpeg libraries statically and you want to use them to
+build your own shared library, you may need to force PIC support (with
+@code{--enable-pic} during FFmpeg configure) and add the following option
+to your project LDFLAGS:
+
+@example
+-Wl,-Bsymbolic
+@end example
