I am going to risk getting flamed here but you have a problem, and this
Download this (www.kyxpyx.com and see the technology section...)
What I am saying here is see what the data flow is like coming into your
win98 machine by using kasterblaster as a client tuned into your icecast
server (I have not tried this but it may work) in a relay set up. again this
may not work, however if it does, kasterblaster will show you what is coming
across packet by packet in the monitor window from the source feed just as
if it was a client. Then tune into the kasterblaster stream and listen to
the output and see if the information presented to you (long delays in
packet through put) corresponds to what you are hearing for drop outs
(remember that KB has a buffer of 1MB). the point of this is that at least
you will be able to see what is going on, and tell when it happens... This
may help you in determining the cause. You should be next to the icecast box
if possible when you do this to see what the logs are like at the same
time.That little red light in winamp when it kicks in is basically what
kasterblaster will show you when a client is starting to run out of buffers
after a certain number of packets if you know how big the buffer is on the
client unit. You can do some quick math to figure out what it takes to keep
that buffer full. If you see more stalls in the server window coming from
the source icecast server then what is required per second, you can start to
see what is really going on behind the scenes for a client connection. the
end result here is you have a quick little quality of service testing tool
hopefully. I have not gone into a lot of detail in an effort to spare the
rest of this list, so if you have questions, email me on the side, and let's
see if there is something that can be done to track your problem down. You
are probably correct in your assumption that you are doing everything
according to the "instructions" correctly. It's not always a server issue,
and you say the "rest of the net is fine" but have you tried other streaming
(video for example as I noticed you do post work) from a box there running
darwin QT (or KasterBlaster if you don't and don't want to go through the
hassle of setting something like that up for a quick test) or something that
is using straight TCP and see what happens there... ?
Just trying to help.
