No, youtube.com does not really conceal direct links to the video. On the contrary, is provides them in machine-readable way. As a proof of concept, try this piece of mess in context of a page:
fetch('/get_video_info?&format=json&video_id='
+ new URLSearchParams(location.search).get('v'))
.then(resp => resp.text())
.then(text => open(JSON.parse(new URLSearchParams(text)
.get('player_response'))
.streamingData.formats
.filter(i => i.mimeType.startsWith('video/webm'))
// find max height video
.reduce((acc, elt) => acc.height > elt.height ? acc : elt)
.url));
I do not know, how youtube-dl works, though.
