Purpose and scope

What this dashboard measures

Total capture, encoding, network, CDN, and player-buffer delay.

Capture delay ms, Encoding delay ms, Network delay ms, CDN or packaging delay ms, Player buffer ms, and Target latency ms feed the underlying totals beneath the Live-Stream Latency and Delay Calculator headline; Carry Target latency ms in its entered unit for comparison.

Instructions

How to use this calculator

Enter capture, encoding, network, CDN, and player-buffer delay plus a target latency.

  1. Supply Capture delay ms and Encoding delay ms from one Live-Stream Latency and Delay Calculator reporting period.
  2. Supply Network delay ms, CDN or packaging delay ms, Player buffer ms, and Target latency ms without changing the Target latency ms unit.
  3. Calculate the Live-Stream Latency and Delay Calculator and match its headline with underlying totals.
  4. Confirm the unit and convention for Target latency ms before accepting the Live-Stream Latency and Delay Calculator result.

Interpretation

Interpreting the headline metric

The largest component identifies the first optimization target. Reducing a small component cannot overcome a large player buffer.

Audit Capture delay ms, Encoding delay ms, and Network delay ms beside the Live-Stream Latency and Delay Calculator headline; Target latency ms reveals rounding across the underlying totals.

Calculation

Method used

All delay components are summed into modeled glass-to-glass latency and compared with the target.

Glass-to-glass latency = capture + encoding + network + CDN + player buffer delay.

The Live-Stream Latency and Delay Calculator evaluates Capture delay ms, Encoding delay ms, and Network delay ms separately; carry Target latency ms visible outside any percentage, rate, or total.

Calculation method last reviewed: June 21, 2026.

Worked scenario

Example calculation

Example: Two hundred milliseconds capture, one second encoding, network and CDN delay, and a three-second player buffer create several seconds total.

Match Target latency ms with the Live-Stream Latency and Delay Calculator underlying totals before judging the Target latency ms headline scale or units.

Visual audit

Reading the supporting metrics

The Live-Stream Latency and Delay Calculator dashboard places underlying totals beside Capture delay ms, Encoding delay ms, Network delay ms, CDN or packaging delay ms, Player buffer ms, and Target latency ms. Audit Target latency ms in its original unit before accepting the underlying totals or headline status.

Boundaries

Important edge cases and limitations

Jitter, retransmission, adaptive bitrate changes, device decoding, synchronization, and measurement error are excluded.

Adjust Target latency ms in the Live-Stream Latency and Delay Calculator before reading the underlying totals or headline.

Input audit

Checklist for this calculation

  • Audit the Live-Stream Latency and Delay Calculator period and Capture delay ms and Encoding delay ms units.
  • Match Target latency ms with the Live-Stream Latency and Delay Calculator underlying totals.
  • Calculate a fresh Live-Stream Latency and Delay Calculator after any Target latency ms adjust.
  • Carry Network delay ms, CDN or packaging delay ms, Player buffer ms, and Target latency ms beside the Live-Stream Latency and Delay Calculator; include Target latency ms in any saved or shared record.

Practical use

Recommended workflow

Measure each stage from telemetry, optimize the largest contributor, and retain enough buffer for stable playback.

Questions

Frequently asked questions

Why is the player buffer often the largest delay?

Buffered playback trades immediacy for resilience against network variation and segment arrival jitter.

What event should trigger another live-stream latency and delay calculator calculation?

Reconsider the Live-Stream Latency and Delay Calculator when Target latency ms no longer matches the source used for Capture delay ms. A new calculation keeps the cases separate.

Can an error in Capture delay ms shift the live-stream latency and delay calculator output?

Match Capture delay ms with Target latency ms inside the Live-Stream Latency and Delay Calculator reporting basis. Carry the Target latency ms unit aligned with the Capture delay ms period before reading the headline.

Which live-stream latency and delay calculator output is most affected by

Carry Capture delay ms and Encoding delay ms unchanged and adjust Target latency ms once in the Live-Stream Latency and Delay Calculator. Match the Target latency ms component with underlying totals to identify a proportional or threshold effect.
