Is this only for HLS?

Playlist analysis targets HLS (.m3u8). Playback uses the same player stack as /watch. For MPEG-DASH, use the DASH / MPD Checker tool.

Why does Analyze fail but the player works?

Analyze runs fetch() from this origin. Some CDNs allow segment CORS for players but block manifest reads, or the opposite. Try fullscreen player or test from your own domain.

No. Everything runs in your browser except optional “explain error” which sends a short text to our API.

Stream Lab

Ein Tool für HLS: Manifest-Analyse, Varianten-Tabelle, eingebetteter Player und Live-Wiedergabe-Telemetrie — Buffer, Latenz, Codecs und Bitrate.

Stream-URL

HTTPS-M3U8 einfügen (oder eine beliebige URL zum Prüfen)

Erste Schritte

Fügen Sie ein HTTPS-Manifest ein, analysieren Sie es und starten Sie die Wiedergabe — die Wiedergabestatistiken erscheinen in der rechten Spalte.

Wiedergabe-Telemetrie

Von Video.js / VHS, während der Player läuft (Rechtsklick auf den Player → Statistik-Overlay auf dem Video).

Starten Sie die Wiedergabe im Player. Die Messwerte erscheinen hier jede Sekunde.

What does Stream Lab do?

Stream Lab merges link check, health summary, and playlist inspection into one layout: analyze the manifest, read variant bandwidths and URIs, then watch the same URL in the embedded player while telemetry streams to the side panel. Share links embed a snapshot of the last analysis (`?r=`).
