 A description of some of the currently available video encoders
+ at section libopenh264
+Cisco libopenh264 H.264/MPEG-4 AVC encoder wrapper.
+This encoder requires the presence of the libopenh264 headers and
+library during configuration. You need to explicitly configure the
+build with @code{--enable-libopenh264}.
+This encoder currently supports only baseline profile.
+For more information about the library see
+ at url{http://www.openh264.org}.
+ at subsection Options
+The following FFmpeg global options affect the configurations of the
+libopenh264 encoder.
+ at table @option
+ at item b
+Set the bitrate (as a number of bits per second).
+ at item g
+Set the GOP size.
+ at item maxrate
+Set the max bitrate (as a number of bits per second).
+ at item flags +global_header
+Set global header in the bitstream.
+ at item slices
+Set the number of slices, used in parallelized encoding. Default value
+is 0. This is only used when @option{slice_mode} is set to
+ at samp{fixed}.
+ at item slice_mode
+Set slice mode. Can assume one of the follwing possible values:
+ at table @samp
+ at item fixed
+a fixed number of slices
+ at item rowmb
+one slice per row of macroblocks
+ at item auto
+automatic number of slices according to number of thread
+ at end table
+Default value is @samp{auto}.
+ at item loopfilter
+Enable loop filter, if set to 1 (automatically enabled). To disable
+set a value of 0.
+ at item profile
+Set profile restrictions. If set to the value of @samp{main} enable
+CABAC (set the @code{SEncParamExt.iEntropyCodingModeFlag} flag to 1).
+ at end table
 @section jpeg2000
 The native jpeg 2000 encoder is lossy by default, the @code{-q:v}
