Hello list I'm running Icecast 2.3.2. Every few seconds, streams are interrupted by a noticeable glitching or popping sound. It sounds like it's being caused by a buffering or latency problem but I'm not sure how to fix it. If the listener re-connects to the stream it stops the glitching for a few minutes, but eventually it returns. Glitching is also appearing in the dumpfiles created by Icecast. I'm running Icecast 2.3.2 on Fedora, and streaming MP3 using libmp3lame and libshout 2.2.2. Can anybody point me in the right direction to fix this?

At a guess, it sounds like the source stream is lacking in bandwidth if all listeners are suffering from the interruptions? -- Regards, James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...? -------------- next part -------------- An HTML attachment was scrubbed...

Hi James, So why would reloading the listener's stream fix the problem (at least for a while)? If it does turn out to be a source bandwidth issue, is there a way to buffer the stream on the server to reduce the problem? Or simply a case of reducing the bitrate? thanks, Rob On 12 July 2010 11:47, James Bensley <jwbensley at gmail.com> wrote:> At a guess, it sounds like the source stream is lacking in bandwidth if all > listeners are suffering from the interruptions? > > -- > Regards, > James. > > http://www.jamesbensley.co.cc/ > > There are 10 kinds of people in the world; Those who understand Vigesimal, > and J others...? > > > _______________________________________________ > Icecast mailing list > Icecast at xiph.org > http://lists.xiph.org/mailman/listinfo/icecast > >-------------- next part -------------- An HTML attachment was scrubbed...

What is the bitrate of your stream? 2. How much bandwidth do you have between your source and your streaming server? 3. How many listeners do you have? 4. How much bandwidth does your streaming server have to service listeners? These should help us narrow down your problem. Geoff.

I have a small instance running Fedora dedicated to Icecast and nothing else.
