 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 MPEG-4 Part 2, so users can
+encode to this format without this library.
+
+ at subsection Options
+
+The options follows are supported by the libxvid wrapper. For the
+documentation for the undocumented but listed options, please see
+ at ref{codec-options,,the Codec Options chapter}.
+
+ at table @option
+ at item b
+
+ at item g
+
+ at item qmin
+
+ at item qmax
+
+ at item mpeg_quant
+
+ at item threads
+
+ at item bf
+
+ at item b_qfactor
+
+ at item b_qoffset
+
+ 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.
+
+ at item cgop
+Enable closed GOP.
+
+ at item global_header
+Place global headers in extradata instead of every keyframe.
+
+ at end table
+
+ at item trellis
+
+ at item me_method
+Set motion estimation method. Possible values in the decreasing order
+of speed and increasing order of quality:
+
+ at table @samp
+
+ at item zero
+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}.
+
+ at item epzs
+Enable all of the things described above, plus advanced diamond zonal
+search for 8x8 blocks, half-pixel refinement for 8x8 blocks, and motion
+estimation on chroma planes.
+
+ at item full
+Enable all of the things described above, plus extended 16x16 and 8x8
+blocks search.
+
+ at end table
+
+ at item mbd
+Set macroblock decision algorithm. Possible values in the increasing
+order of quality:
+
+ at table @samp
+
+ at item simple
+Use macroblock comparing function algorithm (default).
+
+ at item bits
+Enable rate distortion-based half pixel and quarter pixel refinement for
+16x16 blocks.
+
+ at item rd
+Enable all of the things described above, plus rate distortion-based
+half pixel and quarter pixel refinement for 8x8 blocks, and rate
+distortion-based search using square pattern.
