[request] Add option to prefer HTTP over RTMP (and vice versa) for supported sites.

[PinkPandaKatie]

Some sites, like LiveLeak, support both HTTP and RTMP streaming for some videos. Since rtmpdump is kind of flaky, it would be nice to be able to select HTTP.

The LiveLeak extractor currently just chooses the first file it sees, without giving the user the option. Here is a temporary patch which just forces LiveLeak to look for HTTP first:

diff --git a/youtube_dl/extractor/liveleak.py b/youtube_dl/extractor/liveleak.py

Can you name an example URL that would be improved by this patch? For our test video http://www.liveleak.com/view?i=757_1364311680 I only get the HTTP download. In any case, the proper way is to extract all URLs and return them, and let the youtube-dl format handling code figure out which format/URL to pick.

This is the one I was trying to to download: http://www.liveleak.com/view?i=f93_1390833151

Thank you, with that URL it's easy to test. This issue has been fixed in youtube-dl 2014.01.30 and newer (type youtube-dl -U to update).
