Comment (by blm-ubunet@…):

 recordings from 0.24+fixes/0/25+fixes/0.26+fixes..
 All my dvb-t recordings (H264) have beginning corrupt/missing to "next"
 keyframe. My recordings are set to start on SEQ.
 (All==every file checked so far)
 ffprobe reports there are NO "coded_picture_number" from 0 to about 24.
 I expect the "next" keyframe is about 25.

 If I make a test file from recording (ffmpeg) I get
 "coded_picture_numbers" from zero..
