| Can SFUs and MCUs be friends? |
| When talking about videoconferencing, there are usually two different roads you can take: you can either use an SFU (Selective Forwarding Unit) and have all media relayed as it is with no transcoding, or use an MCU (Multipoint Control Unit) instead to decode all streams and encode a composed mix of all the contributions. Both approaches have pros and cons, so picking one over the other is usually a matter of trade-off. It's not always a binary matter, though: as a matter of fact, there are actually many cases where using both in an orthogonal way may make a lot of sense, in order to have one complement the shortcomings of the other, or extend the functionality you can get out of either when used on their own. This presentation will try to present some of these use cases, to show how SFUs and MCUs can actually be good friends, rather than strict and exclusive alternatives. |
