Why does my link fail with a CORS error?

Browsers only allow cross-origin downloads when the server sends permissive CORS headers. If the host blocks them, the stream cannot be fetched from a web page.

Does it support encrypted streams?

Yes, AES-128 encrypted segments are decrypted locally using the key URI in the playlist, provided that key is publicly reachable.

Can I download DRM-protected video?

No. Widevine, FairPlay and PlayReady protected content cannot be decrypted, and downloading it would be unlawful.

Why is the output MP4 and not TS?

MPEG-TS segments are remuxed into a fragmented MP4 container so the result plays in any modern player without conversion.

Is my video uploaded to a server?

No. Every frame is decoded, processed and re-encoded inside your browser with Canvas, Web Audio and MediaRecorder. The file never leaves your device.
