and bypass downloading metadata about individual videos as well as the
videos themselves (for youtube playlists), because even just the
metadata can take many minutes or hours in case of thousands of videos
because youtube-dl's can be annoyingly verbose, confusing, doesn't tell
us the things we're interested in, and doesn't tell us where the
messages originate
finish_frag_download, instead of locking around monkey-patching, to
allow different threads to youtube-dl concurrently, but still not
interfere with each other
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:
