I’m going more in deep with the Dependency Descriptor extension support required for AV1 and also enabled for VP9 (1196318 - chromium - An open-source project to help move the web forward. - Monorail), and seems that the default scalabilityMode value used in the mediasoup demo (S3T3_KEY) is not included in the draft specifications (Scalable Video Coding (SVC) Extension for WebRTC).
Is there something that I’m missing about this? Thanks
AFAIR S3T3_KEY was in a previous version of the draft. Anyway, mediasoup threats “S” and “L” the same way.
