Download M3U8 to MP4 with Command-line Tools (programmatic method)

There are more than one command-line tools capable of downloading M3U8 to MP4, such as FFmpeg, yt-dlp, N_m3u8DL-CLI and more. From personal experience, the combination of yt-dlp plus FFmpeg is still the best option - yt-dlp offers excellent download speed, and FFmpeg helps to combine the video chunks and merge audio. But it may take you some time to figure out how it works if you know little about command-line interfaces.

How to download M3U8 to MP4 with yt-dlp + ffmpeg:

Step 1. Download and install yt-dlp and FFmpeg tools on your computer. If you've installed the downloader before, use the command yt-dlp -U to update to latest version.

Step 2. Launch the command-line interpreter. On Windows, type “cmd” in the search bar to find the Command Prompt and open it. On Mac, open the Terminal app from applications .

Step 3. Type yt-dlp "URL", and hit Enter to execute the command. Replace URL with the actual M3U8 link you copied in advance.

This basic command will fetch the best quality for you. If the video and audio are separate files, FFmpeg will merge them automatically after downloads.

Bonus: How to convert M3U8 to MP4 with FFmpeg alone:

If you only have FFmpeg installed, it can also convert M3U8 to MP4 video without yt-dlp, but the speed can be somehow slower.

In the command-line interpreter, type ffmpeg -i “m3u8-URL” -c copy output.mp4 and hit Enter to run it.

This will also preserve the best quality and save to MP4 format with original codecs without re-encoding.

Can I Download M3U8 to MP4 Online?

Maybe, visit https://m3u8.dev/ to have a try. When I entered a test M3U8 link and clicked "MP4 Download", it didn’t respond at all. Then I selected “TS Download”, and it successfully downloaded the video in TS format, but the saved .ts video file cannot be opened or converted to MP4. So either it only supports a small number of M3U8 links or it’s broken now.

Troubleshooting Tips

Fix some common issues you may encounter when downloading M3U8 to MP4.

1. Downloaded video has no audio/video.

If this happens, make sure you have the right M3U8 link first, not the single audio or video stream link. If you’re using VLC or browser extensions, try to download the video and audio files separately and merge them manually later; or try to use a more powerful video downloader or the FFmpeg method.

2. Fail to load/detect/open the M3U8 link.

The M3U8 URL may be expired and invalid. Many web servers set expiry time for M3U8 URLs to prevent unauthorized sharing and downloading. Please refresh the video page and copy the active M3U8 URL again, then download it immediately.

3. Can't download some M3U8 streams.

Some M3U8 streams are protected by Digital Rights Management (DRM) or from a paid service, they are not downloadable. In such cases you might have to use a recording program like OBS to record the video.

 

Conclusion

By following the methods above, you can download most M3U8 streams to MP4 for easy playback on all devices and media players. There isn't really a one-size-fits-all approach to downloading all M3U8 videos, it depends on the site and your own needs.
