I tried to add reentrancy to mpg123 sometime ago (quick hack of a couple of
hours), but failed because I forgot to duplicate the windowing filter,
that means you were able to open multiple streams , but when you played
more than one stream simultaneously you heard a loud noise, because the
windowing filter coefficients were screwed up by the other streams.
:-)
Eric, please drop us a note when you got the re-entrancy working.
I'm interested too in a fast and reentrant mp2/mp3 decoding lib.
FYI: Xaudio is a nice fast (similar speed as mpg123) and re-entrant MPEG layer
1,2,3 decoding lib, ( http://www.xaudio.com ) , of free apps there is no
license to pay, for commercial ones, I think the license is $2 - $5.
Not that you get binary-only libs, no opensource, but the API works very well,
and has been ported to various platforms, windoze included. :-)
Benno.
