because we expect to capture videos from individual watch pages, and
often processing thousands of videos with youtube-dl before the page is
ever opened in the browser is not desired behavior and is a crawling
problem
which was causing awfulness like this:

i.e. pushing the same stitched-up video to a bunch of wrong places :(
video extraction using generic extractor in case of very large url (more
than 20 mb) that youtube-dl interprets as html, to avoid spinning
forever here:

Mostly at startup. Now that brozzler claims sites in batches for
brozzling, we have situations where we start up a whole bunch of
browsers at the same time. That's probably why in some cases they are
slow to establish the websocket connection.
