Description

Functions

GST_VAAPI_WINDOW_XWINDOW()

#define             GST_VAAPI_WINDOW_XWINDOW(window)

Macro that evaluates to the underlying X11 Window of window

Parameters

window

a GstVaapiWindow

gst_vaapi_window_x11_new ()

GstVaapiWindow *
gst_vaapi_window_x11_new (GstVaapiDisplay *display,
                          guint width,
                          guint height);

Creates a window with the specified width and height . The window will be attached to the display and remains invisible to the user until gst_vaapi_window_show() is called.

Parameters

display	a GstVaapiDisplay
width	the requested window width, in pixels
height	the requested windo height, in pixels

Returns

the newly allocated GstVaapiWindow object

gst_vaapi_window_x11_new_with_xid ()

GstVaapiWindow *
gst_vaapi_window_x11_new_with_xid (GstVaapiDisplay *display,
                                   Window xid);

Creates a GstVaapiWindow using the X11 Window xid . The caller still owns the window and must call XDestroyWindow() when all GstVaapiWindow references are released. Doing so too early can yield undefined behaviour.

Parameters

display	a GstVaapiDisplay
xid	an X11 Window id

Returns

the newly allocated GstVaapiWindow object

gst_vaapi_window_x11_get_xid ()

Window
gst_vaapi_window_x11_get_xid (GstVaapiWindowX11 *window);

Returns the underlying X11 Window that was created by gst_vaapi_window_x11_new() or that was bound with gst_vaapi_window_x11_new_with_xid().

Parameters

window

a GstVaapiWindowX11

Returns

the underlying X11 Window bound to window .

gst_vaapi_window_x11_is_foreign_xid ()

gboolean
gst_vaapi_window_x11_is_foreign_xid (GstVaapiWindowX11 *window);

Checks whether the window XID was created by gst_vaapi_window_x11_new() or bound with gst_vaapi_window_x11_new_with_xid().

Parameters

window

a GstVaapiWindowX11

Returns

TRUE if the underlying X window is owned by the caller (foreign window)

Types and Values

GstVaapiWindowX11

typedef struct {
} GstVaapiWindowX11;

An X11 Window wrapper.
