	This part describes the APIs with repect to Multimedia Camcorder.
	Camcorder is for recording audio and video from audio and video input devices, capturing
	still image from video input device, and audio recording from audio input
	device.

	@par
	Camcorder can be reached by calling functions as shown in the following
	figure, "The State of Camcorder".

	@par
	@image html	camcorder_state.png	"The State of Camcorder"	width=12cm
	@image latex	camcorder_state.png	"The State of Camcorder"	width=12cm

	@par
	Between each states there is intermediate state, and in this state,
	any function call which change the camcorder state will be failed.

	@par
	Recording state and paused state exists when the mode of camcorder is
	video-capture or audio-capture mode. In case of image-capture mode, CAPTURING state will
	exsit.

	* Attribute @n
	Attribute system is an interface to operate camcorder. Depending on each attribute, camcorder behaves differently.
	Attribute system provides get/set functions. Setting proper attributes, a user can control camcorder as he want. (mm_camcorder_set_attributes())
	Also, a user can comprehend current status of the camcorder, calling getter function(mm_camcorder_get_attributes()).
	Beware, arguments of mm_camcorder_set_attributes() and mm_camcorder_get_attributes() should be finished with 'NULL'.
	This is a rule for the variable argument.
	@par
	Besides its value, each Attribute also has 'type' and 'validity type'. 'type' describes variable type that the attribute can get.
	If you input a value that has wrong type, camcorder will not work properly or be crashed. 'validity' describes array or
	range of values that are able to set to the attribute. 'validity type' defines type of the 'validity'.
	@par
	A user can retrieve these values using mm_camcorder_get_attribute_info().
	Following tables have 'Attribute name', 'Attribute macro', 'Type', and 'Validity type'. You can refer '#MMCamAttrsType' and '#MMCamAttrsValidType'
	for discerning 'Type' and 'Validity type'.
