I meant the "broken non-IDR frame".

Paul, if I find a way to change only the audio frame's PTSes, what would I
change them to?
Don't I want to simply drop them, instead?
_But_ if I use -noise=drop, I'll drop the video packets, too, and the video decoder will malfunction
because of the broken IDR frame.
This is not a simple problem, eh?

Is there some secret to the trim filter?
--filter_complex "split=2[i5][i6],

[i6]trim=start_frame=138745:end_frame=246719[o6],
[o5][o6]concat=n=2"
I get "dup=481", instead, and wind up with 20.061708[3..] seconds of black
frames preceding the
segment I want, and the frame rate is 19.181 FPS.
You need to rewrite audio timestamps, otherwise you get 'empty' gaps.
Have you found an atrim expression that works?
I tried adding atrim=start=20.062. Now playback goes for 20.061708[3..] sec of black frames, then
freezes for another 20.061708[3..] sec, then continues as though nothing strange had happened.
Actually changing the audio frame's PTSes is going to be harder than hard.
