@section opengl
OpenGL output device. Deprecated and will be removed.
To enable this output device you need to configure FFmpeg with @code{--enable-opengl}.
This output device allows one to render to OpenGL context.
Context may be provided by application or default SDL window is created.
When device renders to external context, application must implement handlers for following messages:
@code{AV_DEV_TO_APP_CREATE_WINDOW_BUFFER} - create OpenGL context on current thread.
@code{AV_DEV_TO_APP_PREPARE_WINDOW_BUFFER} - make OpenGL context current.
@code{AV_DEV_TO_APP_DISPLAY_WINDOW_BUFFER} - swap buffers.
@code{AV_DEV_TO_APP_DESTROY_WINDOW_BUFFER} - destroy OpenGL context.
Application is also required to inform a device about current resolution by sending @code{AV_APP_TO_DEV_WINDOW_SIZE} message.
@subsection Options
@table @option
@item background
Set background color. Black is a default.
@item no_window
Disables default SDL window when set to non-zero value.
Application must provide OpenGL context and both @code{window_size_cb} and @code{window_swap_buffers_cb} callbacks when set.
@item window_title
Set the SDL window title, if not specified default to the filename specified for the output device.
Ignored when @option{no_window} is set.
@item window_size
Set preferred window size, can be a string of the form widthxheight or a video size abbreviation.
If not specified it defaults to the size of the input video, downscaled according to the aspect ratio.
Mostly usable when @option{no_window} is not set.
@end table
@subsection Examples
Play a file on SDL window using OpenGL rendering:
@example
ffmpeg -i INPUT -f opengl "window title"
@end example

@section sdl
SDL (Simple DirectMedia Layer) output device. Deprecated and will be removed.
For monitoring purposes in FFmpeg, pipes and a video player such as ffplay can be used:
@example
ffmpeg -i INPUT -f nut -c:v rawvideo - | ffplay -
@end example
"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"
