Introducing WebRTCSink

A new Rust based GStreamer plugin for easy WebRTC

Sequence is proud to announce WebRTCSink, a comprehensive Rust-based GStreamer element for WebRTC streaming, designed to handle encoding, congestion control, and packet loss mitigation automatically. Built on top of webrtcbin, it functions as a sendonly sink that accepts raw audio/video streams and manages the encoding process.

Key Features:

• Configurable codec selection through properties

• Built-in signalling protocol with optional custom implementation

• Dynamic bitrate adjustment based on network congestion

• Packet loss mitigation through retransmission and Forward Error Correction (FEC)

• Real-time statistics monitoring and visualization

The element requires the latest GStreamer main branch and will be included in the upcoming 1.20 release.

Development roadmap:

• Rust-based signalling server

• Additional congestion control algorithms

• flexfec implementation

• Comprehensive integration testing
