[Mp4-tech] gaps_in_frame_num_value_allowed_flag...???

[Deepak Singh]

Dear Experts,
  I have query related to gaps_in_frame_num_value_allowed_flag and frame_num.
  As per my understanding of standard when
  gaps_in_frame_num_value_allowed_flag is 0 then frame_num will be in
 non decreasing order and increases till next IDR frame.
The value of frame_num  increase with plus 1 with respect to previous
 reference frame.
  Let me put an example for it.
  Lets assume B- frame is not used for reference.
  In h.264 coded bitstream the frames are : (frame_num as per my
  understanding it will be)
  Note: gaps_in_frame_num_value_allowed_flag = 0
  Coded Frame  :  IDR -> P-> P-> B->B-> P-> P->IDR->....
  Frame_num    :  0         1    2     3    3    4    5     0
  My question is for the same sequence if
  gaps_in_frame_num_value_allowed_flag = 1 and non- existing frame
  exists as
  Note: gaps_in_frame_num_value_allowed_flag = 1, NE = Non Existing Frame.
  Coded Frame : IDR -> P-> NE->P-> B->B->NE->NE-> P-> P->IDR->....
  Frame_num   :  0       1     ?      ?     ?    ? ?     ?       ?     ?     0
  How the frame_num value will behave for the above situation???
