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

Special thanks to Mathieu Duponchelle for the initial implementation! View the source here: https://github.com/centricular/webrtcsink
