27 This part describes the APIs with repect 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
33 Camcorder can be reached by calling functions as shown in the following
34 figure, "The State of Camcorder".
37 @image html camcorder_state.png "The State of Camcorder" width=12cm
38 @image latex camcorder_state.png "The State of Camcorder" width=12cm
41 Between each states there is intermediate state, and in this state,
42 any function call which change the camcorder state will be failed.
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

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.
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'.
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'.

1928 * mm_camcorder_create:\n
1929 * Create camcorder object. This is the function that an user who wants to use mm_camcorder calls first.
1930 * This function creates handle structure and initialize mutex, attributes, gstreamer.
1931 * When this function success, it will return a handle of newly created object.
1932 * A user have to put the handle when he calls every function of mm_camcorder. \n
1933 * Second argument of this function is the field to decribe pre-setting information of mm_camcorder such as which camera device it will use.
1934 * Normally, MM_VIDEO_DEVICE_CAMERA0 is for Main camera(or Mega camera, Back camera),
1935 * and MM_VIDEO_DEVICE_CAMERA1 is for VGA camera (or Front camera). If you want audio recording,
1936 * please set MM_VIDEO_DEVICE_NONE. (No camera device is needed.)
1938 * @param[out] camcorder A handle of camcorder.
1939 * @param[in] info Information for camera device. Depending on this information,
1940 * camcorder opens different camera devices.
1941 * @return This function returns zero(MM_ERROR_NONE) on success, or negative value with error code.\n
1942 * Please refer 'mm_error.h' to know the exact meaning of the error.
1943 * @see mm_camcorder_destroy
1945 * @post Next state of mm-camcorder will be MM_CAMCORDER_STATE_NULL
1946 * @remarks You can create multiple handles on a context at the same time. However,
1947 * camcorder cannot guarantee proper operation because of limitation of resources, such as
1948 * camera device, audio device, and display device.
