Sending stream to multiple computers

[xandu]

I have to implement a solution for a videoconference in my company. It uses a "star" topology - i.e. the general manager sends video to 6 local managers and the 6 managers sends video to the general manager. Each local manager sees only the general manager, and the general manager sees all. They all must hear each other.
My question is: can I use VLC to send video to 6 participants at the same time, or I must create some sort of "relay" or "repeater" to do this job?
Then, can I extract only audio from an incoming stream and re-broadcast it?
Thank you!

I remember like I saw it in this forum, but I couldnt find by now. May be you can search, hope you find the solution.

Hi, INCARA i search in the forums, but only find this post, and other post with vlvc were very old, all links dead, I read that the vlvc was not a very good application, so I want to do it with vlc.

Thanks

Here is the solution of your question:

-> First, you need to download VLC.
-> Install it on each computer that you want to be able to watch the streams.
-> Run VLC on the main computer. This is going to be the "master", which will be broadcasting to all the others. The "master" won't show video locally. You'll have to open a new VLC and connect like others if you want to watch on the main computer.
-> Click File, then Wizard (ctrl+W in XP). This opens the streaming/transcoding wizard. Make sure Stream to Network is selected and click Next.
-> For the Input screen, you have two choices. If the file/disc is already in the playlist, then go with Existing Playlist Item and select the appropriate item from the list you want to play. Conversely, you can Select a Stream to choose from a browse box which files/disc to play . After getting the playlist set up, click Next.
-> On the Streaming screen, select RTP Multicast. Below that, fill in the special Multicast address you will be broadcasting to (see Tips). Click Next.
-> Click Next again for the Encapsulation Format.
-> For Additional Streaming Options, enter one for Time-to-Live unless you have multiple routers on your network, which is pretty rare for home networks. You could put 2 or 3 just to be safe, if you suspect that there is more than one.
-> Under Time-to-Live is SAP announce. Check the box and enter a name or phrase that will identify the stream for people in their playlists, like Elm Street Theater, or Casablanca... whatever.
-> Now click Finish to begin the streaming of the files.
-> Open another VLC instance (on another computer or the same computer) and open the Playlist (ctrl+P in XP). Click Manage, Services Discovery, then SAP announcements. An item should appear in your playlist called, strangely enough, Session announcements. The default time for announcements is 5 minutes. After that time you should see the name or phrase for your stream under the Announcements item. Double click on the name and it should start playing.
-> If you don't want to wait for the SAP, go to File, Open Network Stream. Choose UDP/RTP Multicast and enter the multicast address that the video is being broadcast to/on. Leave the port numbers alone and click Ok to begin the video playing on the remote VLC. Do this for each computer who wants to watch.

See that was so easy.
