The Stream Detector is a Chrome extension that allows users to detect and track playlists and subtitles used by various streaming protocols such as Apple HLS, Adobe HDS, MPEG-DASH, and Microsoft Smooth Streaming. This addon is a port of the popular Firefox addon and provides an easy way to monitor URLs, download video and audio files, and even customize download commands.

With The Stream Detector, users can simply click on the filenames in the addon's popup menu to copy the URLs. These URLs can then be transformed into readymade download commands for tools like yt-dlp, FFmpeg, Streamlink, hlsdl, or N_m3u8DL-CLI. The download commands include important headers such as User-Agent, Cookie, and Referer, ensuring a seamless downloading experience.

The addon also offers an options page where users can customize their experience and directly download media files. However, it's important to note that popular streaming platforms like YouTube, Vimeo, and Facebook may not be supported by this addon due to their proprietary technologies. In such cases, it is recommended to use dedicated tools like youtube-dl/yt-dlp for downloading from these platforms.

Please be aware that the Chrome version of The Stream Detector may have some limitations compared to the Firefox version. However, it still provides a valuable solution for tracking and downloading streams on the Chrome platform.
