 Encoding ffpresets for common usages are provided so they can be used with the
 general presets system (e.g. passing the @option{pre} option).
 
+ at section libxvid
+
+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
+ at 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.
+
+ at subsection Options
+
+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.

+
+ at item flags
+Set specific encoding flags. Possible values:
+
+ at table @samp
+
+ at item mv4
+Use four motion vector by macroblock.
+
+ at item aic
+Enable high quality AC prediction.
+
+ at item gray
+Only encode grayscale.
+
+ at item gmc
+Enable the use of global motion compensation (GMC).
+
+ at item qpel
+Enable quarter-pixel motion compensation.

+Enable closed GOP.
+
+ at item global_header
+Place global headers in extradata instead of every keyframe.

+Use no motion estimation (default).
+
+ at item phods
+ at item x1
+ at item log
+Enable advanced diamond zonal search for 16x16 blocks and half-pixel
+refinement for 16x16 blocks. @samp{x1} and @samp{log} are aliases for
+ at samp{phods}.
+

+Enable all of the things described above, plus advanced diamond zonal
+search for 8x8 blocks, half-pixel refinement for 8x8 blocks, and motion

+Enable all of the things described above, plus extended 16x16 and 8x8
+blocks search.
