Synchronization

The goal of this plugin is to allow two or more LiSP sessions running on different PCs to be synchronized during a performance (no edit synchronization). The two session are supposed to be identical, so, only user interaction with the cues are replicated on other sessions.

How to use

The plugin usage is quite simple, the only thing to do, is to add the remote session you want to “control” to the peer-list, this can be done via Tools > Synchronization > Mange connected peers

Linux Show Player - Manage synchronization peers

On the left you can find the peers list, on the right the following buttons:

  • Discover peers: Allow to search for other sessions in the network;
  • Manually add peer: Allow to manually add a peer, using it’s IP address;
  • Remove selected peer: Remove the selected peer;
  • Remove all peers: Remove all the peers.

To easily retrieve the (local) IP address Tools > Synchronization > Show your IP will display the current IP address of the PC.

How it works

Once a session is connected, user actions are replicated on the connected one. This is achieved by sending some info over the network, by default the 8070 and 50000 (for the discovery) ports are used, those values can be changed in the configuration file $HOME/.linux-show-player/config.cfg.

Two or more sessions can be mutually connected, this way all the sessions share the same “state”.
