It is failing even with ~2 seconds.. so yes, I am waiting at least that
long.

Sorry, I should have been clearer: it only works for delays lower than 1
second (or ~2 seconds with a lower framerate).
If I make the min-threshold-time longer, I get the "black output"
problem I am trying to solve. (or sometimes, just one frozen frame)

Here's an example of it getting stuck with just 2 seconds of delay
(max-size-time is high enough for that already):
