LOLA: Low Latency Audio Visual Streaming System
3.6. TCP/UDP ports used by LOLA
LOLA will use by default ports TCP 7000, UDP 19788 and UDP 19798 for service
communication and audio/video streaming. It is thus required that no restrictions apply for these
ports (e.g. due to network or Windows firewall settings or local network administration policies). If
you experience problems like “no connection”, or “video OK but no audio”, or “audio OK but no
video” or “remote video window open but remains black screen” it is likely that some port filtering
is affecting your connection. Please check your local network policies and also ask the remote site
to do the same.
