In my opinion, per-layer (spatial or temporal) stats require a lot of work. Let's start with the simplest one. For example, how about adding three fields to `RTCOutboundRTPStreamStats`? `spatialLayerCount`: For SVC, returns the number of spatial layers configured. Returns 1 for simulcast or unicast. `temporalLayerCount`: Returns the number of configured temporal layers. (We can mix simulcast and temporal scalability in VP8 or H.264.) `spatialLayerActiveCount`: For SVC, returns the number of spatial layers currently in use. May be less than `spatialLayerCount` due to bandwidth limitations. Returns 1 for simulcast or unicast. I don't know if it is possible to change the number of temporary layers at runtime. https://webrtc-review.googlesource.com/c/src/+/285420 is a prototype implementation in libwebrtc. -- GitHub Notification of comment by bc-lee Please view or discuss this issue at https://github.com/w3c/webrtc-stats/issues/673#issuecomment-1330179734 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
