[Icecast] Using Icecast relay function with dynamic IP at remote source end
ok let see if I can translate it to broadcaster terms for ya :) A icecast server can be set up to accept direct source connection. ie dark ice( which i do agree runs better on the machine where icecast server is. ) I do use it to trans-code the mount to different encoding. THe icecast server can also set up as a relay, where it pulls in from the another server. Primary used to pull the stream from a icecast server. Then make it available to be acceded by clients from it mounts. But, BUTT is designed to stream to an icecast server, and does very well. http://icecast.org/docs/icecast-2.4.1/relaying.html Master is the source server (where the source comes from) ad Slave is the relay. THe connection is initiated by the slave to the master. BUTT ---MASTER ========= SLAVE ===== Clients --- can be local host or lan or wan private or public == is public connections wans/lans/... If you need more bandwidth you can setup/rent other SLAVEs on other networks to augment you bandwidth. It lot easier to have 1 master and bunch of slaves to spreading the bandwidth out, It easier to maintain a single master with many mounts + it easy to trace problems down with sources going to a common Master. I tend to diverge from your question a bit. But, your encoder should work find with broadcaster to the icecast server by itself. I have had it done for the past 10 years. The only real issue s when you encode the stream higher then what he bandwidth can handle. remember the source clients use the UPLOAD speed of you connection and the client use the UPLOAD speeds. In the USA it no uncommon to have uploads speeds to be far slower then you can download. Also I am talking about how fast the connection is not how much data you have in a month. It get really confusing when you talk about bandwidth, since they call both bandwidths.One is how big your pipe is and other how much you get through the pipe in a given time. Lot of the extra above fore those reading this and nee d a little more clarity :) David SLAVE looks a the master waiting for something to do. When it sees the mount it relays it.

[Icecast] Using Icecast relay function with dynamic IP at remote source end
Ha! Terms even a broadcaster can understand! Many many thanks. If BUTT is considered to be as good a transporter as Icecast, then I will stick with what I'm doing, if for no other reason than, "Master is the source server (where the source comes from) and Slave is the relay. THe connection is initiated by the slave to the master." Slave may not know where the Master is. Master (on a table in front of me at a remote music event) may be at unknown/dynamic IP address. I'd have to find my IP address, Teamview into the server computer at the station, stop the Icecast service, edit icecast.xml with my current IP address, and re-start the Icecast service. Is there any way to "push" a connection from Master to Slave? Slave is at a fixed IP address. -- That Jack Elliott (541) 848 7021 KPOV 88.9 FM High Desert Community radio Producer, The Wednesday Point Host, The Sunday Classics On 4/19/2017 8:47 PM, David Saunders wrote:> ok let see if I can translate it to broadcaster terms for ya :) > > A icecast server can be set up to accept direct source connection. ie > dark ice( which i do agree runs better on the machine where icecast > server is. ) I do use it to trans-code the mount to different encoding. > > THe icecast server can also set up as a relay, where it pulls in from > the another server.

I have spent part of today at a site which uses all of the above programs. A change of mains power service should be more reliable. Recent conversations here prompted this review. We have 2 machines running Darkice & Icecast2 each connected to a fibre service. Darkice is set to provide a high grade aac+ stream for 3 broadcast sites, a rebroadcast / logger [256b] mp3 local recording, and a skinny [56b] mp3 'website' stream. You can shape the mp3 audio with lowpass an highpass options. We have experimented with various formats and have gone with what the majority of players will handle. Everything runs at 48000 which is the native sampling rate of the on board sound cards. One less resampling process saves time and processor capacity. That's 2 Fibre cables in to the site, and 2 ISP's. One or other can fail, and they do, There was once a short period when both were out. We feed 3 broadcast sites and one IP relay site, which runs Icecast2. The relay site is a paid service provider and allows 200 connections. The relay site 'pulls' the audio from the fixed IP at the studio. It is configured and maintained by the service provider. This in turn feeds several relay services, some of them 'free', and a website player. I have no idea what the external links use, but everything works. There are more links than we know about as some just seem to add us to a list. We have a 'popular' programme! I note some of the relay sites resample our audio. The original installation was ADSL and the uplink could not manage 4 clients because ADSL uplinks are really low grade. In fact we think the ISP's were controlling the bandwidth more than they would admit. We used one upload to an IP relay site. Now we have fibre the relay transmitters connect direct. Each darkice machine has a logger which is a script running as an hourly cron job. We use a high sample rate because a number of the live programmes get rebroadcast. The playout machine is limited to wav and mp3. We use BUTT in a laptop connected to a mobile phone as a hotspot for OB's [Remotes] and the G3 uplink is generally good. We are fortunate that the cellular coverage here is mostly very good and very few users occupy the uplink. We have used local ADSL and Fibre. If we have an event where there will be a huge number of people live streaming from their smartphones, which tends to overload the network we make sure we have a non cellular circuit. BUTT feeds one of the studio Icecast2 servers and comes up in the studio on a second computer running Chrome. Audio plays direct into the desk from the #2 computer soundcard. BUTT is simple, works in windows, and its easy to adjust the bit rate to suit the link. It works better with a bit of headroom. Keep the levels down! Avoid processing. Sample as high as possible. The big advantage of this setup is the cost. The darkice/icecast2 machines are old ex lease junk computers we get for next to nothing. Once configured they run with no screen keyboard or mouse. The HP ones have better power supplies. OS and software is free. They reboot and run BUTT runs on Windows which the frontline are comfortable with. Everyone has a laptop. It does not matter what IP BUTT has, it sends to the fixed IP at the studio on port [ 8000 ] with a mount like /liveBroadcast.mp3 We get around crossovers by arranging presentation to accomodate the audio delay. Darkice handles multiple encoding with ease. Icecast2 does the transportation BUTT is the simple remote origination solution. regards Robert -- *Raupo Radio* 64 Warner Park Avenue Laingholm Auckland 0604 09 8176358 0221693124 06 650 6087 -------------- next part -------------- An HTML attachment was scrubbed...
