Hmm, input format used by ecasound is important here. If
input-device/file is finished, processing is stopped (engine status =
"finished"). For wav/raw/cdr/stdin/stdout, standard libc calls are
used (ferror() and feof()). Formats handled by libaudiofile (aif/snd)
have their own mechanism... I tested streaming soundcard input through
a named FIFO from one ecasound process to another and it seemed to
work ok. I used raw format.
Btw; Ecasound doesn't grow input-file length during processing (shown by
"fstatus"), but this shouldn't be a problem.
