If you watch the live stream in real time in the social channels, you will notice a delay of anywhere between 5-20 seconds between the video preview in the Loola Studio and the video in the social channel.
This delay happens due to buffering and some format conversions in the social networks and is not caused by Loola (Loola adds about 0.5 sec of lag time).

Note: even though there's a delay, the audio and video should be in sync while watching the social channels.
