Ämne: Broadcasting mp3 with SoundJam 2.5.3 and QTSS 4
Hello to all participants
This list has been very useful to me indeed. I got a post from Lee
Azzarello, to whom I am very thankful for helping me to solve my problem in
trying to broadcast mp3 in real-time.
Before you can begin broadcasting mp3, you have to go to QTSS´s
administration (myservertcp-ipaddress:1220). Here you have to change your
password in "Change my MP3 broadcast password" once for all. With SoundJam
2.5.3 installed in my client (only for classic) I went to "Stream
Broadcast" command and used the following settings:
Server address: myserverstcp-ipaddress:554/icy_0
Port: is empty, because I have used it in the server address above
Password: the one I used in the QTSS´s administration pages (see above)
After that I went to the "SoundJam Encoder" by pressing the button
"Configure..." and configured the parameters accordingly. I was able to
stream 128 kbps in very high quality. You can try different settings, if
you want. Sometimes I noticed that if I stopped broadcasting for trying to
change some of my encoding configurations, SoundJam would not want to
connect to the server. I went to the administration pages and found out
that QTSS still had my ipnr. on the connected user lists. By closing
SoundJam and opening it again, I was able to get through. I think it
happened because I was trying to listen to my own broadcasting with iTunes
from my own machine. If I only listened to my broadcasting from other
clients, the problem wouldn´t occur.
Lee Azzarello has an explanation for the very mysterious url used in
"Server address":
"I think SoundJam might use the outdated Shoutcast protocol. QTSS uses the
newer Icecast protocol. The main difference between the two is that Icecast
supports mountpoints, which shoutcast doesn´t. QTSS also defaults to port
554. So SoundJam would have to broadcast to myhost.com:554. Then you could
connect your MP3 player to http://myhost.com:554/icy_0 (icy_0 is the
default mountpoint for Shoutcast)."
I hope the above explanation is clear enough for all of them that are
trying these things out. Now I have a full net radio by only using Mac´s. I
have 20 Mac clients with iTunes listening to my broadcast.
I have tried with WinAmp and it worked as broadcaster as well as SoundJam.
Nevertheless if I tried to listen to my broadcasting via WinAmp for Windows
(mind that there is a version for Mac´s also, which can´t be used as
broadcaster yet) I experienced that the sound was filled with small jumps.
It didn´t matter how low the bitrate was. I made many hypotheses about it:
network congestion, processor power in my Windows machine, QTSS sucks, and
Windows sucks. But none of those were right. By going deep in WinAmp
preferences, I found out that if I chose not to show music titles in real
time, the whole player would behave totally the same as iTunes for Mac´s:
smooth sound and high quality. I don´t understand the cause of this
problem. Has anybody a suggestion?
