Description

When giving youtube-dl a mpd from YouTube it won't detect any formats in it. It also downloads only the mpd itself. The mpd is from a live stream after the stream was finished (I attached the file, as YouTube links expire after 6 hours), but this happens with all of the mpds from YouTube I tested. FFmpeg on the other hand detects all formats in the mpd, so it must be an issue with youtube-dl.

youtube.txt

I tested a mpd from another site which worked as it should.
Strangely youtube-dl uses mpds from YouTube without a problem, when giving youtube-dl a YouTube URL.

You are not supposed to pass these URLs directly.

Why closing when this is appearently a problem, where youtube-dl doesn't recognize the mpd?
