None of them are used by default, their use has to beexplicitly requested by passing the appropriate flags to @file{./configure}.@section AMRAMR comes in two different flavors, wideband and narrowband. FFmpeg can makeuse of the AMR wideband (floating-point mode) and the AMR narrowband(floating-point mode) reference decoders and encoders.Go to @url{http://www.penguin.cz/~utx/amr} and follow the instructions forinstalling the libraries. Then pass @code{--enable-libamr-nb} and/or@code{--enable-libamr-wb} to configure to enable the libraries.Note that libamr is copyrighted without any sort of license grant. This meansthat you can use it if you legally obtained it but you are not allowed toredistribute it in any way. @strong{Any FFmpeg binaries with libamr supportyou create are non-free and unredistributable!}@chapter Supported File Formats and CodecsYou can use the @code{-formats} option to have an exhaustive list.@section File FormatsFFmpeg supports the following file formats through the @code{libavformat}library:@multitable @columnfractions .4 .1 .1 .4@item Supported File Format @tab Encoding @tab Decoding @tab Comments@item 4xm                       @tab   @tab X    @tab 4X Technologies format, used in some games.@item ADTS AAC audio            @tab X @tab X@item American Laser Games MM   @tab   @tab X    @tab Multimedia format used in games like Mad Dog McCree.@item ASF                       @tab X @tab X@item AVI                       @tab X @tab X@item AVM2 (Flash 9)            @tab X @tab X    @tab Only embedded audio is decoded.@item AVS                       @tab   @tab X    @tab Multimedia format used by the Creature Shock game.@item Bethsoft VID              @tab   @tab X    @tab Used in some games from Bethesda Softworks.@item BFI                       @tab   @tab X    @tab Brute Force & Ignorance, used in Flash Traffic: City of Angels.@item C93                       @tab   @tab X    @tab Used in the game Cyberia from Interplay.@item CIN                       @tab   @tab X    @tab Multimedia format used by Delphine Software games.@item Creative VOC              @tab X @tab X    @tab Created for the Sound Blaster Pro.@item CRYO APC                  @tab   @tab X    @tab Audio format used in some games by CRYO Interactive Entertainment.@item DV                        @tab X @tab X@item DXA                       @tab   @tab X    @tab This format is used in the non-Windows version of the Feeble Files         game and different game cutscenes repacked for use with ScummVM.@item Electronic Arts Multimedia  @tab    @tab X    @tab Used in various EA games;
