a GstVaapiWindow |
Returns : |
the parent GstVaapiDisplay object |
void gst_vaapi_window_show (GstVaapiWindow *window
);
Flags a window to be displayed. Any window that is not shown will not appear on the screen.
|
a GstVaapiWindow |
void gst_vaapi_window_hide (GstVaapiWindow *window
);
Reverses the effects of gst_vaapi_window_show()
, causing the window
to be hidden (invisible to the user).

a GstVaapiWindow |
Returns : |
TRUE if the window is fullscreen |
void gst_vaapi_window_set_fullscreen (GstVaapiWindow *window
,gboolean fullscreen
);
Requests to place the window
in fullscreen or unfullscreen states.
|
a GstVaapiWindow |
|
TRUE to request window to get fullscreen |

);
Retrieves the height of a GstVaapiWindow
|
a GstVaapiWindow |
Returns : |
the height of the window , in pixels |
void gst_vaapi_window_get_size (GstVaapiWindow *window
,guint *pwidth
,guint *pheight
);
Retrieves the dimensions of a GstVaapiWindow.
|
a GstVaapiWindow |
|
return location for the width, or NULL
|
|
return location for the height, or NULL
|
void gst_vaapi_window_set_width (GstVaapiWindow *window
,guint width
);
Resizes the window
to match the specified width
.
|
a GstVaapiWindow |
|
requested new width for the window, in pixels |
void gst_vaapi_window_set_height (GstVaapiWindow *window
,guint height

,guint width
,guint height
);
Resizes the window
to match the specified width
and height
.
|
a GstVaapiWindow |
|
requested new width for the window, in pixels |
|
requested new height for the window, in pixels |
gboolean gst_vaapi_window_put_pixmap (GstVaapiWindow *window
,GstVaapiPixmap *pixmap
,const GstVaapiRectangle *src_rect
,const GstVaapiRectangle *dst_rect
);
Renders the pixmap
region specified by src_rect
into the window
region specified by dst_rect
.
|
a GstVaapiWindow |
|
a GstVaapiPixmap |
|
the sub-rectangle of the source pixmap to
extract and process. If NULL , the entire pixmap will be used. |
|
the sub-rectangle of the destination
window into which the pixmap is rendered. If NULL , the entire
window will be used. |
Returns : |
TRUE on success |
gboolean gst_vaapi_window_put_surface (GstVaapiWindow *window
,GstVaapiSurface *surface
,const GstVaapiRectangle *src_rect
,const GstVaapiRectangle *dst_rect
,guint flags
);
Renders the surface
region specified by src_rect
into the window
region specified by dst_rect
. The flags
specify how de-interlacing
(if needed), color space conversion, scaling and other postprocessing
transformations are performed.
