• cbs_h265 : Detect more reference combinations which would overflow the DPB

  cbs_h265 : Detect more reference combinations which would overflow the DPB
  In total, the number of short term references (from the selected short
  
  term ref pic set), the number of long term references (combining both the
  
  used candidates from the SPS and those defined in the slice header) and
  
  the number of instances of the current picture (usually one, but can be
  
  two if current picture reference is enabled) must never exceed the size
  
  of the DPB.  This is a generalisation of the condition associated with
  
  num_long_term_pics in 7.4.7.1.
  We use this to apply tighter bounds to the number of long term pictures
  
  referred to in the slice header, and also to detect the invalid case where
  
  the second reference to the current picture would not fit in the DPB (this
  
  case can't be detected earlier because an STRPS with 15 pictures can still
  
  be valid in the same stream when used with a different PPS which does not
  
  require two DPB slots for the current picture).
