Comment (by blm-ubunet@…):

 A recording from 2009 (dvb-t h264) has coded picture_number 0
 (pict_type=I) but is missing coded_pict 1 to 7..

 Later recordings are using B frames as ref frames.
 Recording from 2010 has coded_pict_num 1-3 missing.
 Later recordings have first coded_pict_num of value 24 but have 25-27
 missing..
