 @end table

+ at section AVOptions
+
+These options are provided directly by the libavformat and libavcodec
+libraries. To see the list of available AVOptions, use the
+ at option{-help} option. They are separated into two categories:
+ at table @option
+ at item generic
+Can be set for any container or codec. Generic options are listed under
+AVFormatContext options for containers and under AVCodecContext options
+for codecs.
+ at item private
+Are specific to the given container or codec. Private options are listed
+under their corresponding containers/codecs.
+ at end table
+
+For example to write an ID3v2.3 header instead of a default ID3v2.4 to
+an MP3 file, use the @option{id3v2_version} private option of the MP3
+muxer:
+ at example
+ffmpeg -i input.flac -id3v2_version 3 out.mp3
+ at end example
+
+Note -nooption syntax cannot be used for boolean AVOptions, use -option
+0/-option 1.
