Hi Everyone,

Did anyone have feedback or other thoughts on Sergio’s proposal?

Thanks!

Currently there is no standard protocol (like SIP or RTSP) designed for ingesting media in a streaming service, and content providers still rely heavily on protocols like RTMP for it.

This transcoding step is always present in traditional streaming to support e.g. ABR, and comes at no cost. However webrtc implements client-side ABR, by means of simulcast and SVC codecs, which otherwise alleviate the need for server-side transcoding. Content protection and Privacy Enhancement can be achieve with End-to-End Encryption, which preclude any server-side media processing.
