Subject: [yahoo] Fix video extraction (fixes #1521)
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=9c15e9de849641143e7654f2656c68e066fe9e2f;p=youtube-dl

[yahoo] Fix video extraction (fixes #1521)

There's no need to use two different methods.
Now we can also download videos over http if possible.
Also run the test for rtmp videos, but skip the download.
