Livestream Latency Calculator

Livestream Latency Calculator

Wondering why your stream lags behind real-time? This calculator breaks down total end-to-end latency by contributing factor.

Total Latency = Encoding Delay + Network Transit + Player Buffer Delay + CDN Delay

Example

500ms encoding, 300ms network, 2000ms player buffer, 1000ms CDN delay:

Total Latency = 3,800 ms → ~3.8 seconds end-to-end latency

Why Standard Streaming Protocols Add Significant Delay

Standard HLS/DASH streaming protocols commonly introduce 15-30+ seconds of latency due to segment-based buffering, where video is chunked into several-second segments before being distributed and buffered by viewer players.

When Lower Latency Actually Matters

Specialized low-latency streaming protocols (LL-HLS, WebRTC) can reduce this to just a few seconds, which matters significantly for interactive live content like auctions, live Q&A, or competitive gaming streams, where real-time viewer interaction depends on minimizing this delay.
