109 * This function creates bin of video source.
110 * Basically, main pipeline of camcorder is composed of several bin(a bundle
111 * of elements). Each bin operates its own function. This bin has a roll
112 * inputting video data from camera.
114 * @param[in] handle Handle of camcorder context.
115 * @return This function returns MM_ERROR_NONE on success, or the other values on error.

122 * This function creates bin of audio source.
123 * Basically, main pipeline of camcorder is composed of several bin(a bundle
124 * of elements). Each bin operates its own function. This bin has a roll
125 * inputting audio data from audio source(such as mike).
127 * @param[in] handle Handle of camcorder context.

146 * This function creates main pipeline of camcorder.
147 * Basically, main pipeline of camcorder is composed of several bin(a bundle
148 * of elements). And if the appilcation wants to make pipeline working, the
149 * application assemble bin that is proper to that task.
150 * When this function is called, bins that is needed for preview will be composed.
152 * @param[in] handle Handle of camcorder context.
