[RFC 6/7] media: uapi: h264: Clean slice invariants syntax elements

Ezequiel Garcia
2020-06-23T18:29:30Z

The H.264 specification requires in its "Slice header semantics"
section that the following values shall be the same in all slice headers:

pic_parameter_set_id
frame_num
field_pic_flag
bottom_field_flag
idr_pic_id
pic_order_cnt_lsb
delta_pic_order_cnt_bottom
delta_pic_order_cnt[ 0 ]
delta_pic_order_cnt[ 1 ]
sp_for_switch_flag
slice_group_change_cycle

and can therefore be moved to the per-frame decode parameters control.

Field 'pic_parameter_set_id' is simply removed in this case,
because the PPS control must currently contain the active PPS.

Syntax elements dec_ref_pic_marking() and those related
to pic order count, remain invariant as well, and therefore,
the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size
are also common to all slices.
