unable to download youtube live stream

[2011]

This is probably a duplicate of some past bug, but I didn't see anything exactly like it.

This is a live stream (don't know if those eventually get converted to static videos).

Looks like it's a duplicate of #5703 and #5545

[2011]

I have never seen the 92-95 formats (or the HSL identifier) before.

Unlike 5703, I was unable to get any of the formats while the stream was live.
