@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.
