Let's try 720p WebM (45):

youtube-dl -f 45 --verbose https://www.youtube.com/watch?v=jLnL63cXmD8
[debug] System config: []
[debug] User config: []

Indeed, 720p and 1080p WebM do exist, confirmed with KrISS dwld. Seems like Youtube is messing in it's code. Again.

youtuble-dl soft-fails and drops down to format 43 (640x360) with --prefer-free-formats. This format is correctly extracted.

Duplicate of #1578, I'm sorry but the current solution is to keep trying until Youtube serves itag 45.
Thanks for the report.
