Karl, I've managed to patch up my branch of Icecast to do the batching. Checked everything with valgrind and tested it extensively. It looks good. Tcpdump now shows nice size frames (mostly 1400 bytes). Any reason why you're not settings the MTU to something closer to 1500?

Hi all, I'm running an Icecast-2.2 server with at peak times some 50 sources and 500 concurrent listeners all using low-bitrate 16kpbs streams. I'm experiencing some connection losses at these peak times ("Client connection died" message in error.log). The machine running Icecast has a 100Mbit connection to the internet. It is a Celeron 2.4Ghz machine with 1Gbyte of main

Hi all, I have a question about the relationship between the "queue-size" and the "burst-size" <limits> parameters. Q: When a client connects is the burst-size immediately added to the queue-size? If this is the case then the slack for a 16kpbs client goes down from 50 sec (102400[queue-size] / 16kbps = 50 sec) to 18 seconds ( (102400 - 65536[burst-size]) / 16kpbs =

Do you mean you can relay within a single icecast server instance? So the relay is running on the same icecast process from which it is relaying a stream?

In my case that's not needed, but yes it would be really nice if all mount options could be retrieved from the database using an authenticated URL.

Please post to the mailing list the next time Ralf. I'm not using yp directory listings, but I can guess why it is not working. You're probably missing the libcurl.so library in your chroot jail directories. Here's the listing of files I have in the chroot jail: -----%< cut here > ls -R .: admin etc lib opt usr var web ./admin: listclients.xsl listmounts.xsl

Thanks for the suggestion. It turns out that debug for ices told me nothing but debug for icecast 2.2.0 showed that it was terminating the source at the same place in the playlist, apparently due to a lack of trailing metadata in one particular file -- icecast saw it as end of stream. After checking code updates on the TRAC system, I installed the kh branch of icecast (kh13) and this seems

Hi, I have used the SVN icecast-2.1-trunk version in my production system at http://audioserver.nl for 2 months now without problems. The fallbacks work fine as long as you make sure that the format (sampling frequency and bitrate) of the mount and it's fallback match. I have also patched the icecast-2.1-trunk version (patch not published yet, needs work to extract) to enable fallback of

Hi all, I have an icecast setup with 20+ sources. During peak times some 20 sources will be connected with a total of some 250 listeners more-or-less equally divided over the 20 sources. All streams are running at a measly 16 kbps. There is enough bandwidth to/from the server. During these peak times I see very high CPU usage for icecast 98-99%. The system I'm running is an Intel Celeron

Hi all, The URL authentication is great for reducing the administration overhead in running one or more icecast instances for lost of mountpoints and lots of listeners. However because the URL authentication is <mount> specific you still need to create a mountpoint for each (in our case) customer. Would it be possible to have a global URL authentication section which would apply to

Hi, You can if your machine is assigned two IP addresses. Then you can bind the webserver to port 80 on the first IP-adres and bind icecast to port 80 on the second IP-address. Hope this is helpful.

(I'm aware that this patch is not likely to be accepted in the upstream source because Icecast doesn't really support MP3, but I thought it worthwhile to send it here in case anyone wishes to modify their local source with it.) Background: Icecast does not make any attempt to demarcate the boundaries between MP3 frames, and when a listening client connects to the server it generally

Hi Geoff, Thanks, that sounds like a good idea. I've just tried it and of course it works. Then I discovered that when the original source is not connected icecast doesn't fall through to the fallback mount. Is this a known problem?

I'm curious about why you would want to run Icecast on port 80. Geoff Justin Bot wrote: >Care to shed some light on this?

Karl, It would certainly be a useful feature for me and I guess others. The current solution with ezstream works but listeners all end up at the same (current) point in the mp3 file. With the mp3 file as a fallback each individual listener would want to start hearing it from the start. This might be more difficult to implement with the single-q that is in the current trunk code, I don't know.

Hi, I've been using icecast-2.3.1 for some time now and it is really working well for me, solid as a rock (no crashes) and running 100's of streams and 1000's of listeners, but in order to support authentication and have easier configuration I want to start using the url authentication (esp. the stream_auth) and mount-name wildcards that are supported by icecast-2.3.2-kh17.

I have a patch on icecast-2.2.0 svn version which was written specifically to support SimpleCast users to retrieve the stats for their mountpoint and only that mountpoint. This is based on per mount-point username password. Using HTTP authentication the client can retrieve only http://hostname/admin/stats.xml given the correct username/password. This will only return the stats for that

Hello all, We (at ibiblio.org) are evaluating several projects and products for getting good analytics from icecast. Specifically, we have explored cacti and awstats. I am writing because I would like users of this list to send me their experiences with analytics and monitoring packages and products. I would like details such as time for initial deployment, time and steps to add an addiitonal
