Function Documentation

static void vout_display_DeleteWindow	(	vout_display_t *	vd,
		vout_window_t *	window
	)			`[inline, static]`

Referenced by DirectXCloseWindow(), and GetWindow().

void vout_display_GetDefaultDisplaySize	(	unsigned *	width,
		unsigned *	height,
		const video_format_t *	source,
		const vout_display_cfg_t *
	)

Computes the default display size given the source and the display configuration.

This asssumes that the picture is already cropped.

static vout_window_t* vout_display_NewWindow	(	vout_display_t *	vd,
		const vout_window_cfg_t *	cfg
	)			`[inline, static]`

Asks for a new window with the given configuration as hint.

b_standalone/i_x/i_y may be overwritten by the core

Referenced by DirectXCreateWindow(), and GetWindow().

void vout_display_PlacePicture	(	vout_display_place_t *	place,
		const video_format_t *	source,
		const vout_display_cfg_t *	cfg,
		bool	do_clipping
	)

Computes how to place a picture inside the display to respect the given parameters.

This assumes that cropping is done by an external mean.

Parameters:

	p_place	Place inside the window (window pixel unit)
	p_source	Video source format
	p_cfg	Display configuration
	b_clip	If true, prevent the video to go outside the display (break zoom).
