  27         This part describes the APIs with respect to Multimedia Camcorder.
  28         Camcorder is for recording audio and video from audio and video input devices, capturing
  29         still image from video input device, and audio recording from audio input
  30         device.
  31
  32         @par
  33         Camcorder can be reached by calling functions as shown in the following
  34         figure, "The State of Camcorder".

  41         Between each states there is intermediate state, and in this state,
  42         any function call which change the camcorder state will be failed.
  43
  44         @par
  45         Recording state and paused state exists when the mode of camcorder is
  46         video-capture or audio-capture mode. In case of image-capture mode, CAPTURING state will
  47         exist.

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