Question

How to achieve multi-party audio conference with FMS?

Hi, folks,

    I need to design a Flash based web conference service. One requirement is it should allow multiple users to speak concurrently like a normal conference call facility does. However, I'm wondering whether Flash has any support of such mechanism. Can multiple client publish their Mic object to the same stream hosted by the FMS and get mixed together there? Or, rather, I have to create multiple streams for each speaker to publish to respectively and instruct every audience to subscribe all of these sterams and do the mix on the receiver side?

   Your suggestions is highly appreciated. Thanks.

Regards.

Weikai.

    It's the later... FMS has no way of mixing multiple streams into a single stream.Each publisher will need to publish to a unique stream, and each subscriber will need to subscribe to each of the streams over a separate NetStream.

    Yeah.  That totally blows too.  Remember the bandwidth per stream grows exponentially.

    1 person  = 2 streams ( one up, one down )

    2 people  = 4 streams ( two down, two up )

    3 people  = 9 streams ( three down, three up)

    etc.

    Its gets expensive bandwidth wise.  If you're talking about a large group of users you may want to look into creating a "designated" speaker type of situation.
