From: Michael Orlitzky Date: Mon, 16 Jun 2008 03:43:00 +0000 (-0400) Subject: Added the Infoq site. X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=1b8ef3e1c23144e7ca2f8f6724d123b12ae9081c;p=dead%2Fwhatever-dl.git Added the Infoq site. Added support for infoq.com by adding a new website class. Infoq attempts to obscure their video URLs with Base64 encoding which is easy enough to get around. I implemented this, and a couple of tests for the new class. --- diff --git a/src/websites/infoq.rb b/src/websites/infoq.rb new file mode 100644 index 0000000..fe05562 --- /dev/null +++ b/src/websites/infoq.rb @@ -0,0 +1,69 @@ +# +# Copyright Michael Orlitzky +# +# http://michael.orlitzky.com/ +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
