Streaming Format Demo (shiftcast48)
Switch between WebRTC real-time, HLS timeshift (3 min · 48 hours), MSE timeshift (12 hours), VOD, lip-sync live, and more by a single tap. Compare the millisecond clock above the video against the timestamp inside the stream to feel each format's latency at a glance: WebRTC is ~0.2 s, HLS is several to a dozen seconds.
Format comparison
| Format | Latency | Rewind | Primary use |
|---|---|---|---|
| WebRTC | ~ 0.2 s | — | Two-way, surveillance, real-time control |
| HLS live (3 min) | 3-10 s | 3 min | Multi-device viewing, general purpose |
| HLS 48h timeshift | 5-15 s | 48 h | TV-style operation with deep rewind |
| MSE 12h timeshift | 1-3 s | 12 h | Relays & conferencing with rewind |
| VOD (MP4 / HLS) | n/a | — | Pre-recorded distribution |
Latency figures are typical. Real environments depend heavily on bandwidth and device.
