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

Un seul outil pour le HLS : analyse du manifeste, tableau des variantes, lecteur intégré et télémétrie de lecture en direct — buffer, latence, codecs et bitrate.

Commencer

Collez un manifeste HTTPS, analysez-le, puis lancez la lecture — les statistiques de lecture apparaissent dans la colonne de droite.

Télémétrie de lecture

Depuis Video.js / VHS pendant la lecture (clic droit sur le lecteur → Stats pour un overlay sur la vidéo).

Lancez la lecture dans le lecteur. Les métriques apparaissent ici chaque seconde.

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=`).
