Remarks

T_DSM_LAUNCH_CAMERA_REQ数据结构:
typedef struct
{
     uint32 preview_x;     /*预览区域的x坐标*/
     uint32 preview_y;     /*预览区域的y坐标*/
     uint32 preview_w;    /*预览区域的宽度*/
     uint32 preview_h;     /*预览区域的高度*/
     uint32 img_w;          /*拍下来的照片的宽度*/
     uint32 img_h;          /*拍下来的照片的高度*/
     uint32 img_qt;         /*图片质量*/
}T_DSM_LAUNCH_CAMERA_REQ;

T_DSM_COMMON_RSP数据结构：
typedef struct
{
     int32 p1;    /*camera句柄*/
     int32 p2;    /*osd层buffer*/
}T_DSM_COMMON_RSP;

Example

/*mrp code*/

T_DSM_LAUNCH_CAMERA_REQ launch={0};
T_DSM_COMMON_RSP *cameRSP = NULL;
int32 len;

launch.preview_h = SCREEN_HEIGHT;
launch.preview_w = SCREEN_WIDTH;
launch.preview_x = 0;
launch.preview_y = 0;
launch.img_h = 32;
launch.img_w = 32;
launch.img_qt =  0;
mrc_platEx( 2501, (uint8*)&launch, sizeof ( T_DSM_LAUNCH_CAMERA_REQ ), (uint8**)&cameRSP, (int32*)&len, NULL );
