How to get m3u8 live files, not real-time mvu8 video files?

I would like to get a live m3u8 file, not a m3u8 DVR, since the latter contains too many segments (4 hours) and is slow and not convenient for downloading and processing.

For example, a sky news feed

www.youtube.com/watch?v=y60wDzZt8yg

What I've done:

Change user agent string on iPad or visit

www.youtube.com/get_video_info?&video_id=y60wDzZt8yg

I could get something like

manifest.googlevideo.com/api/manifest/hls_variant/playlist_type/DVR/signature/11D1EE619ACDCA91661CB6F42597F96F0C86CC1F.742A7B383F4B10A099B1C7AAEF1E15DCD2F160C6/ipbits/0/fexp/9416126%2C9420452%2C9422596%2C9423459%2C9423661%2C9423662/source/yt_live_broadcast/id/y60wDzZt8yg 0,2 / SVER / 3 / key / yt6 / UPN / 0y8ab4RaX_U / expire / 1454380402 / sparams / GCR% 2Cid% 2Cip% 2Cipbits% 2Citag% 2Cmaudio% 2Cplaylist_type% 2Cpmbypass% 2Csource% 2Cexpire / f / 86.172pass.6 /yes/maudio/1/gcr/gb/file/index.m3u8

which contains sub-m3u8 files with multiple permissions.

When opening this file 720p sub-m3u8
