Is it possible to use youtube-dl to download video from a .m3u8
stream file or other livestream formats?
When I copy the video URL into YouTube-dl it spits out:
[https @ 0x7fc351416080] inflate return value: -3, incorrect header check
Last message repeated 15 times
After that it spits out of couple lines of red text that doesn't seem to want to copy in properly, so I took a snippet:
Does anyone know if this is possible?
I'll be using this Live Event from NASA TV as an example:
https://www.youtube.com/watch?v=21X5lGlDOfg
First, list the formats for the video:

Pick the format you wish to download, and fetch the HLS m3u8 URL of the video from the manifest. I'll be using 94 mp4 854x480 HLS 1380k , avc1.4d401f, 30.0fps, mp4a.40.2@128k
for this example:
youtube-dl -f 94 -g https://www.youtube.com/watch\?v\=21X5lGlDOfg

Note that link could be different and it contains expiration timestamp, in this case 1592099895 (about 6 hours).
Now that you have the HLS playlist, you can open this URL in VLC and save it using "Record", or write a small ffmpeg command:
ffmpeg -i \
