[Icecast] Configure Ubuntu Server 16.04 for icecast2

Discussion:

Hi all,
First of all, thank you for supporting us.
I've installed Libretime (https://github.com/LibreTime/libretime) which
user Icecast2 on Ubuntu Server 16.04.
I've also developed a mobile application to listen to stream
myhost:8000/mount.
My problem is when the number of listeners increases up 500 (On live
streaming with butt), the application blockes, and I hardly get info from
myhost:8000/status-json.xsl.
My question is : How shoud I configure my Ubuntu / Icecast / Liquidsoup to
allow more than 5000 listeners to listen music without any issue.

Thanks.

Regards.

Hi BKF,

you can configure icecast to serve thousands of listeners but it's not
going to happen on anything less then an industrial strength internet
connection.

If you have ADSL you can probably handle 5 listeners maybe 10 on an
average service.

If you have VDSL increase that to 15 maybe.

If you have fibre it might do 25.

It all depends on the service provided by your ISP and the condition of
the cabling between the local switch and your location.

They control how much data you can send and recieve even on " unlomited "

Then it dependsÂ on the modem router, and your in house network,
although these are less likely problem areas.

If you want 5000 listeners you have to send audio to a Streaming Service
Provider who has a BIG internet upload capability which costs money.

There are some that charge rather low rates for 200-1000 connections
because they know that while you pay for capability very few stations
have more then one or two listeners on line at any time.

I support one that has up to 200 listeners and we may be at 40 or so
except when there is some critical news breaking which takes us over the
100.

We have a feed for an app and a feed for tunein and a feed for the
website. The app has the highest usage

Hi,
Thank you so much for your reply,
I've a dedicated server in OVH, where I have done speed test for the server
:

****@xxxxx ~> speedtest-cli Retrieving speedtest.net <http://speedtest.net>
configuration...Retrieving speedtest.net <http://speedtest.net> server
list...Testing from OVH SAS (x.x.x.x)...Selecting best server based on
latency...Hosted by fdcservers.net <http://fdcservers.net> (Paris) [1.88
km]: 6.488 msTesting download
speed........................................Download: 900.46 Mbit/sTesting
upload speed..................................................Upload:
282.95 Mbit/s*

Is it enough for up 5k listeners ? Could you please give me best Providers
for streaming ?

Thanks.

Hi,

283000/5000=56.6

So with ~283Mb/s upstream, if you wanted 5,000 listener capacity your
streams would have to have a bitrate of 56.6kb/s or lower.

Cheers,
Jordan

streams would have to have a bitrate of 56.6kb/s or lower.

Speaking conservatively, I would de-rate that number by 50%, or in other words:

0.5*283000/5000=28.3 kb/sec.

This to account for various overheads (TCP/IP packet framing and negotiation, data bursting at stream startup, administrative interface traffic, etc. It all adds up.

Cheers!

Hi Frederick,

Wouldn't overhead (at least partly) already be factored in with the
speed test data/results? Obviously not 100% comparable to audio
streaming, but..

Those speed tests are best case scenario - one big old file where the only overhead would be tcp syn/acks.

5000 x syn/acks and handshakes everytime a client connects would quite a lot of overhead I imagine.

Note that this is an educated guess - I don't run /anything/ on the scale of 5000 users lol

Hi Jake,

Thanks for clarifying. Makes sense, in addition to what Frederick said
re: admin interface, bursting, etc.

Cheers,
Jordan

Bonjour,

*Upload: 282.95 Mbit/s*

is going to choke at about 5 listeners *
*

You need a streaming server provider.

https://shoutca.st/

is an example but there are many.

Don't buy 5k listeners buy 100 and see how it goes.

*regards*

You have confused megabits for kilobits. The number of listeners depends on the bitrate of the stream. Assuming a 64kb/s stream, 282.95 Mb/s will support 4400 listeners, but more likely 4000.
