Rtwatch: Watch videos with friends using WebRTC
Rtwatch is an open-source project leveraging Pion WebRTC and GStreamer to enable perfectly synchronized video co-watching experiences. Unlike other solutions, its key innovation lies in managing all video state on the backend, streaming only current frames to viewers. This ensures universal control over playback, preventing individual caching or unsynced fast-forwarding, a feature appealing to those seeking robust multi-user media solutions.
The Lowdown
Rtwatch is a novel application designed for synchronized video viewing with friends, built upon the powerful combination of Pion WebRTC and GStreamer. It aims to provide a seamless, real-time shared viewing experience where playback controls, such as pausing and seeking, are unified across all participants.
- The system uses Pion WebRTC for real-time communication and GStreamer for media processing.
- Its core distinction is that all video state is maintained on the backend server, not client-side.
- This server-side control means only the current audio/video frames are sent to viewers, preventing them from downloading or caching the video content.
- Crucially, shared controls ensure that when one person pauses or seeks, it applies instantly and uniformly to everyone watching.
- The project provides detailed setup instructions, including Docker deployment and GStreamer installation guides for various operating systems (Debian/Ubuntu, Windows, macOS).
- Users can play videos from local files or remote URIs, with examples provided for both.
- A simple web interface allows users to initiate and control playback, demonstrating multi-tab synchronization.
By centralizing video state and streaming only frames, Rtwatch offers a technically sound approach to group video watching, ensuring a consistent and controlled experience for all participants.
