Icecast - Aug 2004 - Problem with streaming some mp3s (but not all)

Hi!

I would really appreciate if someone could try to help
me out with this... i've been struggling with it for
quite a while now. :(

Anyway, I was trying to use ices to broadcast mp3s
with icecast2 (a recent cvs snapshot of all 3
components from brendan's site). I have it working
fine for some of my mp3s (encoded with lame -b 32) but
with the other mp3s which are actually the ones that I
wanted to broadcast, it doesn't work.

Basically, what happens is, with XMMS, it keeps trying
to reconnect and occasionally will be able to play a
garbled fraction of a second.  With Winamp, it just
sits there, and after a while says something like
error syncing to mpeg stream.  Just doing a plain wget
on the stream and trying to play it with mpg123
results in silence.

The problem mp3s were encoded with lame --alt-preset
cbr 40 and lame --alt-preset cbr 80.  You can access
some example mp3s here:

http://www.svaudio.org/test1.mp3 (works)
http://www.svaudio.org/test2.mp3 (doesn't work-40kbps)
http://www.svaudio.org/test3.mp3 (doesn't work-80kbps)

My DNS is flaky sometimes, so use 68.53.92.187 if you
have problems.

All of the problem mp3s work fine when played
independently, and mp3_check finds no problems.

I realize that I could just reencode these, but I want
to know what settings to avoid and would like to avoid
having to do that if at all possible (there are 40 of
them and they take about half an hour to an hour
each.)

Thanks a lot!

P.S. I would appreiate if you could CC replies to me,
but I'll try to remember to check the list anyways. :)

Hi:

My guess is that ices can't handle 16000 or 32000hz sampling rates.  The
32kbps file is 22050hz and the 80kbps file is 32000hz.  I couldn't get
mpg123 to play test2 remotely, but lame defaults to 32000hz with 40kbps
mono and 16000hz with 40kbps stereo, so I'm guessing this is the problem.
You can either use --resample to force a different sampling rate or pick a
different bitrate.

Geoff.

So there is no way around having to re-encode them
all?
