[Live-devel] Re: Setting a multicast OnDemand server

[Achraf GAZDAR]

Thanks for the fast reply 
you have reason Ross I have not gave much details about my application. In fact I want to implement a Video on demand application based on the following:
when a new client arrives, if he is the first client demanding a movie he will get it on a multicast stream. If we assume that an other client arrives later demanding the same movie, the server will give him the description of the ongoing session (multicast stream initially opened to the first client) and a new description for a new unicast stream to broadcast to him the missed part of the movie.
Thus the client download data from the multicast stream and keeps it on a buffer while downloading and playing data from the unicast stream. After playing all missed data, he send a teardown for the unicast stream and continue playing video from his buffer (filled by the multicast stream).
