HLS Downloader

HLS videos refer to content transmitted using the HTTP Live Streaming (HLS) protocol. HLS is an adaptive bitrate streaming communication protocol developed by Apple, mainly used for delivering audio and video content over the internet.

HLS videos typically consist of multiple short media segments, which are usually TS (Transport Stream) format files, each lasting a few seconds. These segments are stored in a special M3U8 playlist file in a specific order, which instructs the video player on how to fetch and play these segments.

HLS has become one of the most commonly used technologies in online streaming due to its high reliability and broad device compatibility. MPMux can combine all HLS segments into a single MP4 file, so you don't need to use other tools for conversion.

This downloader is only suitable for videos that comply with HLS technical standards. It is not applicable to videos that do not conform to the standards. Additionally, encrypted HLS videos cannot be downloaded using this tool.

If the target video has multiple resolutions, it may result in capturing multiple HLS video URLs representing different resolutions. Also, if video ads on the page are loaded using HLS, their URLs will also be captured. You need to analyze the URL structure to distinguish them. If multiple HLS addresses are captured due to different resolutions, you can choose any one of them, as you can switch resolutions again during the download process.

When MPMux encounters a request failure while downloading a segment, it will automatically retry. If the number of failed requests exceeds a certain threshold, the download task will automatically pause to avoid unnecessary resource waste. The failure may be due to the video server not allowing frequent requests, in which case you should reduce the number of concurrent download requests through the settings. Alternatively, it could be caused by network request timeouts.

Many similar extensions can download video media directly without opening an additional tab. This is because such extensions typically support only static videos, like MP4 or WEBM. For fragmented videos like HLS, a dedicated tab is required to temporarily store and process media segments. While the extension’s popup can also serve as a temporary container for media data, it is not a reliable option since it may close unexpectedly due to any of your actions, leading to data loss.

More importantly, MPMux relies on certain HTML5 APIs during video processing, which are only available in HTTPS environments. Therefore, an HTTPS tab is needed to support this requirement.

Additionally, using a tab as a temporary container is very useful for downloading large files. Typically, downloading large files takes more time, but within a tab, concurrent requests can be made, effectively increasing download speed and reducing download time.

Yes! You only need to install the extension for your browser, and you can use it without registration or login. You can download videos as many times as you want, with no limits!

No! MPMux does not host your videos, keep copies of downloaded videos, or save your download history on the server. All video downloading tasks are completed within your browser, without involving third-party servers, ensuring your privacy!
