Code:
NAL position 0x000158A0 (88224)
  nal_unit_type:  7 "Sequence parameter set"
  profile_idc       = 100 "High"
  constraint_flags  = 16 (0x10)
      constraint_set0_flag = 0
      constraint_set1_flag = 0
      constraint_set2_flag = 0
      constraint_set3_flag = 0
      constraint_set4_flag = 1
      constraint_set5_flag = 0
  level_idc         = 40
  time_scale / 2    = 24000
  num_units_in_tick = 1001
  fixed_frame_scale = 0
Nothing changed. I miss the frame-packing field.
3D encodings with ffmpeg / x264 and --frame-packing=3 also don't show the field. But it should be there.
The other infos can be changed.
In fact, the frame_packing info is inserted as SEI message

Code:
nal_unit_type:  6 "SEI"
  nal_ref_idc: 0
  payload_type: 45 "frame_packing_arrangement"
  payload_size: 7
