 Built with dash support but when opening a dash mpd url corresponding to a
 facebook live stream, "HTTP error 403 Forbidden" is returned as follows.
 However, VLC is able to play the mpd url without any issue.
 Any ideas?

 PS:
 The live video urls from facebook are changing.
 As mentioned in #7540, one can browse current live streams at
 https://www.facebook.com/livemap (a facebook account to log in may be
 necessary).
 The video URL can be copied by clicking the three dot option on the top
 right corner (Copy Link).
 A straightforward way to get the mpd url is using youtube-dl that can be
 installed through conda:
 {{{
 conda install -c conda-forge youtube-dl
 }}}
 Then the mpd url can be retrieved as follows (Here is an example. Please
 get a live one instead),
 {{{
 $> youtube-dl -g
