+XV (XVideo) output device.
+
+This output device allows to show a video stream in a X Window System
+window.
+
+@subsection Options
+
+@table @option
+@item display_name
+Specify the hardware display name, which determines the display and
+communications domain to be used.
+
+The display name or DISPLAY environment variable can be a string in
+the format @var{hostname}[:@var{number}[.@var{screen_number}]].
+
+@var{hostname} specifies the name of the host machine on which the
+display is physically attached. @var{number} specifies the number of
+the display server on that host machine. @var{screen_number} specifies
+the screen to be used on that server.
+
+If unspecified, it defaults to the value of the DISPLAY environment
+variable.
+
+For example, @code{dual-headed:0.1} would specify screen 1 of display
+0 on the machine named ``dual-headed''.
+
+Check the X11 specification for more detailed information about the
+display name format.
+
+@item window_size
+Set the created 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.

+set to 0 by default. The values may be ignored by the window manager.
