Subject: [youtube] Modify the regex to match ids of length 11 (fixes #1396)
X-Git-Url: https://git.cielonegro.org/gitweb.cgi?a=commitdiff_plain;h=8963d9c2661b7de8832b7afcf1cdbc197275d8e3;p=youtube-dl.git

[youtube] Modify the regex to match ids of length 11 (fixes #1396)

In urls like http://www.youtube.com/watch?v=BaW_jenozKcsharePLED17F32AD9753930 you can't split the query string and ids always have that length.
