Subject: eit: Add scraper for first aired date. (#4287).
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c17b34d3b0e0a3ede89ebc5748fce2a3447d0692;p=thirdparty%2Ftvheadend.git

eit: Add scraper for first aired date. (#4287).

Our broadcaster summary often has "(1995) Lorem ipsum", so we
can extract the first aired date of 1995 from this.

Issue: #4287.
