Typedef Documentation

vlc_gl_surface_t

typedef struct vlc_gl_surface vlc_gl_surface_t

Function Documentation

vlc_gl_Create()

vlc_gl_t* vlc_gl_Create	(	struct vout_window_t *	wnd,
		unsigned	flags,
		const char *	name
	)

Creates an OpenGL context (and its underlying surface).

Note

In most cases, you should vlc_gl_MakeCurrent() afterward.

Parameters

wnd	window to use as OpenGL surface
flags	OpenGL context type
name	module name (or NULL for auto)

Returns

a new context, or NULL on failure

vlc_gl_surface_CheckSize()

bool vlc_gl_surface_CheckSize	(	vlc_gl_t *	gl,
		unsigned *restrict	width,
		unsigned *restrict	height
	)

Checks if the dimensions of the surface used by the OpenGL context have changed (since the previous call), and the OpenGL viewport should be updated.

Returns

true if at least one dimension has changed, false otherwise

Warning

This function is intrinsically race-prone. The dimensions can change asynchronously.
