-@c man end DESCRIPTION
-
-@chapter Codec Options
-@c man begin CODEC OPTIONS
-
-libavcodec provides some generic global options, which can be set on
-all the encoders and decoders. In addition each codec may support
-so-called private options, which are specific for a given codec.
-
-Sometimes, a global option may only affect a specific kind of codec,
-and may be unsensical or ignored by another, so you need to be aware
-of the meaning of the specified options. Also some options are
-meant only for decoding or encoding.
-
-Options may be set by specifying -@var{option} @var{value} in the
-FFmpeg tools, or by setting the value explicitly in the
-@code{AVCodecContext} options or using the @file{libavutil/opt.h} API
-for programmatic use.
-
-The list of supported options follow:
-
-@table @option
-@item b @var{integer} (@emph{encoding,audio,video})
-Set bitrate in bits/s. Default value is 200K.
-
-@item ab @var{integer} (@emph{encoding,audio})
-Set audio bitrate (in bits/s). Default value is 128K.
-
-@item bt @var{integer} (@emph{encoding,video})
-Set video bitrate tolerance (in bits/s). In 1-pass mode, bitrate
-tolerance specifies how far ratecontrol is willing to deviate from the
-target average bitrate value. This is not related to min/max
-bitrate. Lowering tolerance too much has an adverse effect on quality.
-
-@item flags @var{flags} (@emph{decoding/encoding,audio,video,subtitles})
-Set generic flags.
-
-Possible values:
-@table @samp
