[spatial svc]Another workaround to avoid using prev_mi We encode a empty invisible frame in front of the base layer frame to avoid using prev_mi. Since there's a restriction for reference frame scaling factor, we have to make it smaller and smaller gradually until its size is 16x16. Change-Id: I60b680314e33a60b4093cafc296465ee18169c19
