StreamLoom: HLS/m3u8 Video Downloader

About

Find HLS (m3u8) streams on the current page, pick a quality, and download an MP4 locally.

Overview:
StreamLoom helps you detect HLS playlists (m3u8) used by a video on the current page. After you select a stream and a quality variant, StreamLoom downloads the playlist segments and remuxes them into an MP4 on your machine.

Important notes:
- DRM-protected streams are not supported.
- Download only content you have the rights to download.
- Very large videos may fail due to browser/extension memory limits.

How to use:
1. Open a page with an HLS video and start playback.
2. Open StreamLoom.
3. Select a detected stream and quality.
4. Click Download MP4.

Permission requirements:
- webRequest: detect m3u8 requests initiated by the active tab to populate “Found streams”.
- scripting: allow “Scan page” to locate m3u8 URLs embedded in the page when network detection misses.
- downloads: save the resulting MP4 file to the user’s device.
- offscreen: run local remuxing in an offscreen document.
- tabs/activeTab: identify the active tab and support “Open source tab”.

Privacy:
StreamLoom does not send data to the developer. It only requests video playlists and segments directly from the site you are viewing in order to create the MP4.
All network requests are made directly from the extension to the video host(s) you are viewing in your browser, solely to download the selected HLS playlist and its media segments. No analytics, tracking, or telemetry is sent to the developer.
