Ringmaster

Ringmaster is a videoconferencing research platform open-sourced along with our paper published at NSDI '23 — Tambur: Efficient loss recovery for videoconferencing via streaming codes, where Ringmaster serves as the basis for developing and benchmarking forward error correction (FEC) schemes in videoconferencing released here.

Ringmaster is designed to be a readable and extensible replacement for WebRTC in videoconferencing research, with the goal of supporting more use cases in the future (e.g., congestion control, multiparty conferencing). Contributions are welcome.

See below for the basic usage of Ringmaster that emulates a 1:1 video call. For any questions, please contact the owner Francis Yan.

Dependencies

  • Required environment: Ubuntu >=18.04
  • Install required packages
    sudo apt install autoconf libvpx-dev libsdl2-dev
    

Building

Compile Ringmaster with

./autogen.sh
./configure
make -j

Emulating a video call

Download a sample raw video ice_4cif_30fps.y4m, which has a resolution of 704x576 and a frame rate of 30 fps.

Next, go to src/app and execute the following commands in two terminals, respectively (run them without any arguments to see the usage):

./video_sender 12345 ice_4cif_30fps.y4m
./video_receiver 127.0.0.1 12345 704 576 --fps 30 --cbr 500

This emulates a 1:1 video call, where the caller compresses the raw video into VP9-encoded video frames with an average bitrate of 500 kbps and transmits the packetized frames to the callee over UDP.
