Functions

static int switch_video_out	(	struct video_desc *	env,
		int	index,
		Uint8	button
	)		`[static]`

Changes the video output (local video) source, controlling if it is already using that video device, and switching the correct fields of env->out. grabbers are always open and saved in the device table. The secondary or the primary device can be changed, according to the "button" parameter: the primary device is changed if button = SDL_BUTTON_LEFT; the secondary device is changed if button = not SDL_BUTTON_LEFT;.

the correct message boards of the sources are also updated with the new status

Parameters:

env	= pointer to the video environment descriptor
index	= index of the device the caller wants to use are primary or secondary device
button	= button clicked on the mouse

returns 0 on success, returns 1 on error

tries to switch the state of a device from on to off or off to on we also have to update the status of the device and the correct message board

Parameters:

index	= the device that must be turned on or off
env	= pointer to the video environment descriptor

returns:

0 on falure switching from off to on
1 on success in switching from off to on
2 on success in switching from on to off
