This configuration mostly copies vp9 configuration for regular video, but is done separately to allow tune av1 svc bitrates independently of vp9. Bug: webrtc:12148 Change-Id: Icd11817ada8f9b6135ee2da57204eadb50de3954 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/195329 Reviewed-by: Philip Eliasson <philipel@webrtc.org> Commit-Queue: Danil Chapovalov <danilchap@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32713}
