  对于IVE_IMG_S方面的API函数，对svp_img数据类型需要做对齐操作，不然会失败。

1.     src_image->virt_addr[0] = sample_svp_convert_ptr_to_addr(td_u64, ext_frame->video_frame.virt_addr[0]);
   
2.     src_image->phys_addr[0] = ext_frame->video_frame.phys_addr[0];
   
3.     src_image->width = ext_frame->video_frame.width;
   
4.     src_image->height = ext_frame->video_frame.height;
   
5.     src_image->stride[0] = ext_frame->video_frame.stride[0];
   
6.     src_image->type = OT_SVP_IMG_TYPE_YUV420SP;//0x2
   
7. 
   
8.     src_image->virt_addr[1] = src_image->virt_addr[0] + src_image->height*src_image->stride[0];
   
9.     src_image->phys_addr[1] = src_image->phys_addr[0] + src_image->height*src_image->stride[0];
   
10.     src_image->stride[1] = ext_frame->video_frame.stride[0];
