Description
Summary of the bug:
when specifying a duration for (anullsec, aevalsrc (havent tried the others) )
and specify the duration in terms of # of samples, it ignores? the statement
and attempts to make a file of infinite duration (thus terminated using ctrl+c else ..)
How to reproduce:

nb_samples sets number of samples per each output frame. It have nothing to do with duration.
