Hello everyone!

What I want to do is to have synchronized playback of my mp3's through computers in different rooms so that all the speakers in my house would be "tuned" to the same stream. Obviously, it gets really irritating really soon when you walk through the house and all of the speakers are out of sync.

At the moment I've setup VLC and it works like a charm, EXCEPT for the synchronization part! Is it at all possible? Should I add this to feature requests?

a "netsync" module is alread available. You have to setup the stream server to act as a "sync reference" (or whatever its supposed to be called) and ask all the clients to use it to sync.

You enable it by adding it to the extra interfaces list

Code: Select all

--extraintf netsync

Help about the "netsync" module :

Code: Select all

 Network synchronisation
      --netsync-master, --no-netsync-master                                  Act as master for network synchronisation
                                 (default disabled)
          Allows you to specify if this client should
          act as the master client for the network
          synchronisation. (default disabled)
      --netsync-master-ip <string>                                  Master client ip address
          Allows you to specify the ip address of the
          master client used for the network
          synchronisation.

(all this is of course available in the prefs if you don't want to use command line options)

You have no idea how good it feels to hear that there's a solution after a whole day of struggling with this!!

So a biiig biiig thank you!

Although I'm still struggling with it. I thought I fixed all the settings properly, but it's not synched yet.

I did this on the server computer: I went to Settings/Preferences/Interface/Control Interfaces and then checked the box for Network Synchronisation. After that I checked the box in its Advanced Settings "Act as master for network synchronisation". Then I saved the properties and went to check the settings for the receiving computer.

For the client machine I checked the box for Network Synchronisation and added the ip address of the server machine to the box "Master Client IP Address".

After that I just started streaming from the server (with "Play Locally" checked) and opened the stream from the other computer. They still weren't synced though.

Is there something obvious I have missed?

yes ... the streaming server should only stream. You need to use another instance of VLC acting as client in order to use the syncing mechanism.
