Stream downloading

Concurrent segment downloads Max simultaneous downloads Speed limit (MB/s, 0 = unlimited) Desktop-helper download folder

Where the desktop helper saves files. Browser (in-page) downloads always go to your browser's Downloads folder.

Simple clear HLS (MPEG-TS) streams are downloaded and remuxed to MP4 in your browser via mux.js. Complex streams (fMP4, DASH, large or long downloads) are handed to the desktop helper, which uses real ffmpeg.

Companion & privacy

Enable desktop helper integration Desktop notifications when downloads finish Embed title & poster (cover art) into downloads Floating download button on pages with media Private jobs (skip new persistent history) Browser history retention (days, 0 = keep until cleared)

Existing records remain until cleared or expired. Desktop history is managed separately in the desktop app.
