Thanks for the report.
This kind of videos is download by parts, using the info in a .m3u8manifest, its url is in the hlsvp field of the video info dictionary.
We need to support multipart videos (#1012 or #995) and add helper methods for m3u8 manifests.

@jaimeMF
There is no need to download this as a multipart video
You can just remove the range parameter from the URL which you can find inside the .m3u8 and you will get the full file.
(6,5GB for 1080p in this case.)

@strex This doesn't work for me, the file that it's downloaded isn't recognized by ffprobe and it can't be played. Also the parts themselves are not playable, while for other m3u8 downloads (like dailymotion) can be played.

[jaimeMF]

They are supported now, but it needs ffmpeg for downloading.
@strex The videos are encrypted, so the file cannot be played directly.

I detected, that recording a youtube live stream still doesn't work. I tested it with https://www.youtube.com/watch?v=-m7VVgaRFio
