Apologies, yes, I misspoke in the original email. That's what I get
for submitting something a couple of weeks after writing it and
assuming I still remembered the context correctly. Sorry for making
you check :-/

What bug to you see? I see correct PTS on current master when running
a simple file-to-file test.

Roger. In that case, I guess the question is whether the issue I
described in another email is best addressed by having a
one-in-one-out buffer inside tpad (like the buffer inside adelay) or
by something else. This is my first time messing with the innards of
ffmpeg, so I'm happy to be steered...
