Description
Summary of the bug:
Some facebook live streaming mpd urls (retrieved by youtube-dl -g) causes parser error for missing root node as follows. There is quite a chance encountering such live streams with parsing issues. In comparison, VLC can play the mpd url without any issue. Hopefully, what is missing can be clarified.
PS: if expired, there should be a bunch at https://www.facebook.com/watch/live/?ref=watch. Select the three dot option on the top right for "Copy Link" to retrieve with tools like youtube-dl.
How to reproduce:
$ ffprobe "`youtube-dl -g https://www.facebook.com/FOX35Orlando/videos/625902281343117/`"

Hi,
If at the time of your retrieving the streaming mpd url, the original live video has ended, there won't be any DASH mpd url returned but only regular '*.mp4' url to access. In that case, there would be no parsing error because the mpd url is not there. Please find one at https://www.facebook.com/watch/live for testing. (e.g. https://www.facebook.com/GameSpot/videos/2709904676001371 as for just now)

Since a live stream may end anytime, the url retrieved may not be a dash mpd for reproducing the issue. So a dash mpd that causes parsing error with wget is fetched as attached FYI.
