WPF interface bridging the m3u8 stream download utility of FFmpeg.
Visit m3u8-dlwrapper.zip for the built binaries, or build the WPF project using Visual Studio on your own. Unzip and run m3u8-dlwrapper.exe on a Windows x64 machine. Enter the clip info to start downloading a .m3u8 stream.
These are what the tool actually does in the backend:
| Option | FFmpeg Command |
|---|---|
| 2x checked | ffmpeg.exe -user_agent "{UserAgent}" -headers "{Cookie}" -i {M3U8Link} -filter_complex "[0:v]setpts=PTS/2[v];[0:a]atempo=2[a]" -map "[v]" -map "[a]" -bsf:a aac_adtstoasc {SaveAs.mp4} |
| 2x unchecked | ffmpeg.exe -user_agent "{UserAgent}" -headers "{Cookie}" -i {M3U8Link} -c copy -bsf:a aac_adtstoasc {SaveAs.mp4} |
All the STDOUT and STDERR (100 latest lines) of ffmpeg.exe wil be redirect and kept in the text area.
Chromium's DevTools panel (F12) is very useful. HLS links can be easily captured under "Network" tab when using ".m3u8" as the filter. Noted that this no longer works for Youtube and Bilibili, but it's still worth trying on some other video sites.
Sometimes your request to a HLS link might be rejected due to incorrect user agent. Override the browser agent to your own with help of the online query: https://www.whatismybrowser.com/detect/what-is-my-user-agent
