Add-on summary
HLS Downloader lets you easily download fragmented media files (with .ts file extension) from the internet.
HLS or HTTP Live steam is a new media format developed by Apple Inc. It contains a master playlist with ".m3u8" file extension. First, the extension downloads the master playlist, and then within the master, it finds playlist content. Each playlist has several fragmented items. All items are displayed in the UI with a download and a remove button. When you press on the download button the extension downloads all fragmented media and merges them all to generate a single media file.
Note #1: the UI for the extension can be opened in the toolbar popup, tab, or a separate window. Please right-click on the toolbar button to choose the appropriate context. Within the UI, there is a toggle button to turn the addon ON or OFF.
Note #2: HLS Downloader is NOT responsible for media contents that you download with this add-on. We strongly recommend that you verify the related media copyright permissions on each website before downloading any media file(s).
Note #3: to download HLS stream you gave 3 options. (1) to add a stream URL manually, please enter the desired URL with the ".m3u8" file extension in the UI. (2) as you browse the internet, this extension monitors the webpages and captures all HLS media files, and if anything found, automatically downloads the playlist and updates the badge number accordingly (only when the addon is turned ON). The third option for downloading the HLS stream is via the context-menu item. Please right-click on ".m3u8" streams and then select - Download with HLS Downloader - from the context menu.
If you have a feature request or found a bug to report, please fill the bug report form in the add-on's homepage.
