The offset could be related to a difference in timestamps. I suggest you
insert the "ashowinfo" filter in front of both audio inputs and compare the
timestamps of the first few frames in the "amovie" case that works and the
"filter_complex" case that does not work, to see if there is any

Can you observe the memory usage growing during the encode?

Also, I suggest you trim your test command line to see exactly what part of
it is causing the error; it may be that the "cannot allocate memory" error
is completely unrelated to the offset problem.
