Could you build this?
No Pion/rtwatch uses real-time WebRTC media pipelines in Go to decode, demux, seek, and synchronously stream video to multiple peers with millisecond precision on the backend.
What it would actually take: The architecture relies on the Pion WebRTC stack in Go, custom RTP/RTCP packet handling, backend media demuxing/decoding (such as FFmpeg bindings or native decoders), and server-side clock synchronization across dynamic peer connections. Achieving smooth pause, seek, and synchronized frame delivery over unreliable networks requires deep expertise in real-time streaming protocols, WebRTC internals, and audio/video codecs.
