Pipelining WebRTC videoconferences in Elixir with Membrane Framework
summary
An Elixir-based SFU built with the Membrane Framework receives SRTP from browsers, parses SDP with the xsdp library, handles ICE/DTLS in an ice bin and RTP decryption in an rtp bin, and forwards tracks via endpoint bins; packaged as membrane_webrtc_plugin and a demo video room. Current demo scales to tens of clients, supports screen sharing, lacks native SIP, shows ~20% core CPU gains from hot-path work (unpublished), and uses crash groups plus telemetry aiming for multi-node and single-room large-scale scaling.
