-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Adrian,
You can stream directly from the source, but in order to avoid the same machine support the broadcasting and generating the stream, i used two machine: o the stream generator o a server on the net that can send 100Mb/sec If you have only a few client or if your stream needs to be view in localnetwork then maybe you can avoid the broadcast server. To use the flux on a webpage i used http://www.flumotion.net/ . You can have a look on the web, then the html needed to use the flux is <video width="600" height="400" autoplay="yes" src="http://stream.pok.me/stream.ogg <view-source:http://stream.pok.me/stream.ogg>" tabindex="0"> </video> Off course you will maybe need some fallback depending on your target.
