@anxdpanic commented on GitHub (Jan 14, 2018):

el=vevo also returns Invalid parameters.

The valid el parameters I was able to find from the player.js; 'leanback', 'embedded', 'detailpage', 'editpage', 'adunit', 'previewpage', 'profilepage'
None seem to return dashmpd anymore unless it's live, my channel, or drm content.
