Did you try watching the result? I had thought that the complaint was that
because of missing segments audio was lagging behind video. Last night I
downloaded News at Ten and let ffmpeg repackage it. There were 14 missing
segments. As each is 10s that is over 2min altogether, on a 24min
programme. Would you buy a book with 10% of the pages ripped out? I found
the problem was the reverse of what I thought. The audio finished 2min
before the video. Wouldn't your method only help if the errors were evenly
distributed? 10% of the content would still be missing.
BBC Business Live was a bit better this morning (b07p4t1f) with hlshd1
having missing segments at 4, 6, 8, 9, 10, 127.
