FIX: media/ted (HTTP download only)

[alech]

I fixed the TED download. Unfortunately, RTMP does not seem to be supported by quvi (or is that just my build!?), so I fall back on the "native downloads", i.e. over HTTP. Unfortunately, max 480p only, then.

RTMP URLs are supported just fine by quvi. quvi doesn't download the final links whether it's HTTP or RTMP, you'll need to pass the RTMP URL to something else, like GStreamer.

I am using quvi with git annex, which seems to do "quvi get $url". If I do that on a TED URL such as
http://www.ted.com/talks/vijay_kumar_the_future_of_flying_robots with the RTMP code enabled, I get:

error: protocol `rtmp' is not supported

This seems to come from the following code:
https://github.com/legatvs/quvi-tool/blob/master/src/get/lget.c#L53-L64

cURL does support RTMP and I am somewhat tempted to patch quvi to support it too, even though my C is worse than my Lua ;-)

How do we solve this problem beforehand, though? At the moment, TED support is broken completely, so I'd say having 480p downloads is better than nothing and once quvi supports RTMP, the RTMP code can be enabled?

It's not supported in quvi-tool, so that's where the fix for that should be.

Hmmm, but with the existing libquvi-scripts code, nobody (using the library or quvi-tool) can download TED videos, which is clearly worse than 480p ;-)
