multicast udp

[vincenthure]

I would like to create a home TV
What I Imagine to do is using VLC as a serveur via UDP multicast
It's working well on my local network, but I didn't succes to configure my router (forwarding the 1234 port to my serveur) to make it working via internet
Is it possible? or not?

Thank's fot help

You will not be able to stream a multicast to the Internet.

Roughly, it can only work if you are connected near the backbone of the internet iirc, so forget it :)

not quite, you cant use multicast UDP over the generic IPv4 (and sometime IPv6 too) web/internet DUE purely to the worlds ISPs filtering/turning off the Multicast protocol on their ISP grade routers and related kit to and from your CPE BB modem sat on your desk for NO good reason, nothing to do with being near a backbone?.

YOU CAN still use Multicast through the internet, but you need to pass it through a Multicast TUNNEL end point such as the old MBONE mTunnel
http://www.cdt.luth.se/~peppar/progs/mTunnel/

"The mTunnel is an application that tunnels multicast packets over an unicast UDP channel. Several multicast streams can be sent over the same tunnel while the tunnel will still only use one port. This is useful if tunneling through a firewall.
The applications primary goal is to allow for easy tunneling of multicast over for instance a modem and/or an ISDN connection.

The mTunnel has a built in Web-server allowing for easy access to information about current tunnels. This server listens by default on port 9000 on the machine where started.

The mTunnel also listens on session announcements for easier tunneling of known sessions.

..."

for some odd reason, NO inovative? VLC devs have ever seen fit to add in a simple generic Multicast point to multipoint tunnel (that your AVC ,whatever TS content and SAP now and next announcements etc could then be fed, so totally bypassing the worlds ISPs restrictions and so forcing the use of wastful Unicast bandwidth the world over), into the long standing core multicast code base, even though the old MBONE multicast network supplyed masses of data and open multicast code that could have been retro-fitted into todays video apps, P2p DHT etc http://bamboo-dht.org/tutorial.html "Marcel has also written a report about his experiences building a multicast protocol on top of Bamboo. It may also be useful for tutorial purposes".
