Icecast 2.0 Released 152

Posted by CowboyNeal from the internet-radio-made-easy dept.
ArcRiley writes "After 3 years of development and 6 weeks of beta testing, Icecast 2.0 has been officially released! Features include support for both MP3 and Ogg Vorbis, a web administration interface, support for listing in directories (such as dir.xiph.org), and is freely available under the GNU GPL for Linux and Windows."

      After years in development and years in alpha testing, The icecast development team has released version 2.0.0 of its streaming media server. Icecast2 supports Ogg Vorbis and MP3 streaming and has many features and functions you would expect from a world class streaming media server.

        Except some important relaying functionality is now dropped. In icecast 1 a relay would time out and stop sourcing the stream if no users are connected to it for a while, and resume the stream if someone connected. Good for saving bandwidth automatically. As far as I can tell this is gone from v2.

It says that it's compatible with Shoutcast servers. Does this mean shoutcast.com's listing servers? Has anyone seen how Shoutcast and Icecast compare as far as memory footprint, system usage, bandwidth usage? or are they more or less the same?
    • I believe it means that a Shoutcast client can access an Icecast server as if it were a Shoutcast server. Icecast has potentially lower bandwidth usage, since it supports Vorbis. Otherwise, I've never noticed much of a difference (I've never used either of them for anything serious).

Other codecs that sound sweet at 64kbps exist (windows media, real, quicktime) but they're not free, so you end up paying more than you save in bandwidth.

    And if you go legal with your streams, some licensing authorities (for want of a better word) haven't been clued in to how good ogg sounds at half the bitrate, so they'll give you a sucky-quality discount.

    All icecast 2 betas I tried were missing a vital feature; the ability to flood audio data out at the start of the TCP connection (rather than deliver it at the stream bitrate) -- this is vital because when you take too long delivering the data your stream can die due to filled queues.

    For example, there may be temporary packet loss on the network that results in TCP data queueing up at the sending side. Now unless icecast can correct for that rate mismatch, you're consistently behind and eventually the stream dies.

    I think they might have now added the fix, which is to step up its send rate from the stream bitrate whenever it has to, i.e. whenever the client falls behind (temporary network glitch). The unfortunate result otherwise is that your streams can die on a flaky network connection, even if the average bandwidth over time is more than enough to handle the audio stream!

      It always worked properly; you misunderstand how the timing has to work.

      When a connection is momentarily interrupted, the streaming server doesn't just stall the timing on the connection; it's still tracking how much data had to go out in a given period of time. The total output at any time will always be up to date. Thus, if the network connection is interrupted momentarily, the data will indeed burst forward to the correct point when connectivity resumes. It's like squeezing off a very stretchy hose for a short time.

      The connection is dropped only if connectivity disappears for longer than a certain threshold. Oh, and naturally, if you're trying to listen to a broadband bitstream over a 28.8 modem, you're going to get kicked pretty quickly. The hose only stretches so far, and if it bursts your connection gets dropped. That's not a bug.

      Also, a client that falls behind on its own will eventually burst the hose. That's a bug in the client; you won't fall further and further behind unless a) your playback rate is way off or b) your buffering is pooched. It's the client's responsibility to accept data at the rate the streaming server sends it. The streaming server's timing is correct; if something happens to mess with the client timing, the client has to deal with that.

      As for 'flooding data at the beginning of a connection', that doesn't really make sense in a system where every client has a configurable, different sized prebuffer.
