@end example
-@section sdl
-
-SDL (Simple DirectMedia Layer) output device.
-
-"sdl2" can be used as alias for "sdl".
-
-This output device allows one to show a video stream in an SDL
-window. Only one SDL window is allowed per application, so you can
-have only one instance of this output device in an application.
-
-To enable this output device you need libsdl installed on your system
-when configuring your build.
-
-For more information about SDL, check:
-@url{http://www.libsdl.org/}
-
-@subsection Options
-
-@table @option
-
-@item window_borderless
-Set SDL window border off.
-Default value is 0 (enable window border).
-
-@item window_enable_quit
-Enable quit action (using window button or keyboard key)
-when non-zero value is provided.
-Default value is 1 (enable quit action).
-
-@item window_fullscreen
-Set fullscreen mode when non-zero value is provided.
-Default value is zero.
-
-@item window_size
-Set the SDL window size, can be a string of the form
-@var{width}x@var{height} or a video size abbreviation.
-If not specified it defaults to the size of the input video,
-downscaled according to the aspect ratio.
-
-@item window_title
-Set the SDL window title, if not specified default to the filename
-specified for the output device.
-
-@item window_x
-@item window_y
-Set the position of the window on the screen.
-@end table
-
-@subsection Interactive commands
-
-The window created by the device can be controlled through the
-following interactive commands.
-
-@table @key
-@item q, ESC
-Quit the device immediately.
-@end table
-
-@subsection Examples
-
-The following command shows the @command{ffmpeg} output is an
-SDL window, forcing its size to the qcif format:
-@example
-ffmpeg -i INPUT -c:v rawvideo -pix_fmt yuv420p -window_size qcif -f sdl "SDL
output"
-@end example
-
@section sndio
