I've been using Icecast and SHOUTcast for several years now, to deliver audio and Video content.

I wonder what kind of alternatives do I have to those two, especially when streaming video. On the client side, what software can I choose from to stream to those servers live?

Making the streams available with Flash would be great, but that's maybe another story. We're still using EdCast, which is kinda dead by now, Shoutcast DSP plugin is not an option, as this tends to crash, etc. Are there any alternatives to that, when livestreaming video?

I'm using Liquidsoap for content generation, mixing, etc. It should work with Icecast, Liquidsoap and if possible SHOUTcast.
