Video Audio Delay
We experienced delays between audio and video transmission on multiple occasions, with delays varying between -600 ms and 600 ms. So quite noticeably. There seems to be a tendency for the delay to grow over the course of a session, but not necessarily. Sometimes there are strong shifts within a very short time. If this is relevant, I can provide recordings.
One recent example is: https://www.youtube.com/watch?v=guQBLrOI8kY
It is a recording of recent talk we hosted in the room ZEGGpolitisch, I believe it was hosted on Arlberg on 21.04.21
The delay of our videostream appears to be rather constant between 200 and 350 ms, while the streams of other participants seems to be more synced see at 01:20:00.
