@alvestrand  VP8/VP9/AV1 all use a single stream for SVC. So it is somewhat tricky to keep statistics on a per-layer basis.  For example, a sender receiving a NACK could be getting feedback on losses within multiple layers, and a receiver sending a NACK would need to track the correspondence between losses and layers.  Also, the SFU will typically adjust the layers forwarded based on the aggregate bandwidth and loss rates.
