A practical guide to HLS playlists and how extensions handle them.
An HLS playlist describes how a player can request a stream. Depending on the source, it can reference one quality or several variants, with audio carried together or separately. An extension has to recognize the playlist and fetch media using the requests the website permits.
HLS is checked for both Stream Katcher plans, FetchV, CocoCut free and paid, and Video DownloadHelper free and paid. That is a format-support mark in the supplied October 9, 2026 infographic, not a guarantee that every HLS page can be saved.
Website access, expiring URLs, encryption and DRM can change what is available. DRM-protected video is outside Stream Katcher's supported download scope. Preview the detected item when possible, and play the saved file before relying on it.
Note: the comparison infographic is dated October 9, 2026. It does not specify product versions or a testing method; results on a particular website can differ.
