                     +Xvid MPEG-4 Part 2 encoder wrapper.
+                    +
                     +This encoder requires the presence of the libxvidcore headers and library
                     +during configuration. You need to explicitly configure the build with
                     +@code{--enable-libxvid --enable-gpl}.
+                    +
                     +The native @code{mpeg4} encoder supports the MPEG-4 Part 2 format, so
                     +users can encode to this format without this library.

+                    +
                     +The following options are supported by the libxvid wrapper. Some of
                     +the following options are listed but are not documented, and
                     +correspond to shared codec options. See @ref{codec-options,,the Codec
                     +Options chapter} for their documentation. The other shared options
                     +which are not listed have no effect for the libxvid encoder.
