Feature Description

Right now if you try to open content which is set to become available in the future like a livestream or a video premiere, you will get an error.
org.schabi.newpipe.extractor.exceptions.LiveNotStartException: This live event will begin in 16 hours.
On YouTube future content will have comments and chat already active alongside a thumbnail and further description of the event or video.
This should be visible before the official start.
Maybe even include a countdown.
