Comment (by blm-ubunet@…):
My recordings are from dvb-t & are AVC with intra-refresh (no IDR).
I observe the seektable offset (from binary byte offset cutting etc) to be
related to the difference in audio pkt PTS & video pkt PTS.
Is MythTV using the audio PTS as the timecode?
Graphing the first hundred or so (mark,offset) from (recordedseek) as
incremental diffs shows the first 2-3 to be abnormal.
Confirming what the keyframes are (& where they are) is problematic.
ffprobe reports no keyframes.
Avidemux shows no keyframes but can count/decode/display frames.
