Description of your issue, suggested solution and other information

When using --dump-single-json --flat-playlist on a Youtube playlist, the url of entries seems to be only the ID instead of the full URL.
It works correctly on other websites like Vimeo.

This is expected.

Hello there, I'm developing a mpv & youtube-dl front-end. AFAIK, mpv only except an URL as input, so is there anyway I can get the URL from on entry of a flat playlist (e.g. {"url": "LMHfD1B78G0", "_type": "url", "ie_key": "Youtube", "id": "LMHfD1B78G0", "title": "An Annual Re-Review of Rainbow Six: Siege"}) w/o redownloading the webpage? I found YoutubeDL.extract_info but that is really slow on bad internet connection.
