### DESIGN OF SLICE MODE ####
# 0 SM_SINGLE_SLICE			| SliceNum==1
# 1 SM_FIXEDSLCNUM_SLICE	| according to SliceNum			| Enabled dynamic slicing for multi-thread
# 2 SM_RASTER_SLICE			| according to SlicesAssign		| Need input of MB numbers each slice. In addition, if other constraint in slice_argument is presented, need to follow the constraints. Typically if MB num and slice size are both constrained, re-encoding may be involved.
# 3 SM_ROWMB_SLICE			| according to PictureMBHeight	| Typical of single row of mbs each slice?+ slice size constraint which including re-encoding
# 4 SM_DYN_SLICE			| according to SliceSize		| Dynamic slicing (have no idea about slice_nums until encoding current frame)
# 5 SM_AUTO_SLICE			| according to thread number	| the number of slices is decided by the number of threads,SliceNum is ignored
