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.

Телеметрия воспроизведения

Из Video.js / VHS во время работы плеера (правый клик по плееру → Stats для оверлея на видео).

Запустите воспроизведение в плеере. Метрики появляются здесь каждую секунду.

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=`).
