On Samba Live, both audio and video streams are sent through a media server—not a P2P connection.
More participants will use more bandwidth, though: while each broadcaster, by default, sends a stream at 512 kbps, we cap each room at 3,072 kbps. If you experience issues with specific users when adding more participants, it is very likely a bandwidth issue.
This room cap works like this:
- 6 broadcasters x 512 kbps = 3,072 kbps (no capping is done with that amount of participants).
- If you introduce a 7th broadcaster, we reduce each broadcaster stream by 50% - so 7 x 256kbps = 1,792 kbps. You can keep adding broadcastings until the total is greater than 3,072 kbps.
- Each time you cross the 3,072 threshold, the broadcaster stream gets halved again (to 128 kbps) and so on.
