TED Support

[aurium]

May be nice to have TED Support for taks: http://www.ted.com/talks/dan_dennett_on_our_consciousness.html and play lists: http://www.ted.com/playlists/82/are_we_alone_in_the_universe.html

TED also provide subtitles and video meta-data.

How to download a video:

Visiting this talk page:
http://www.ted.com/talks/dan_dennett_on_our_consciousness.html

The download dialog gives me this URL to download the video in HD with subtitles:
http://video-subtitle.tedcdn.com/talk/podcast/2003/None/DanDennett_2003-480p-pt-br.mp4

I see in the page code this link inside a noscript area:
<a id="no-flash-video-download" href="http://download.ted.com/talks/DanDennett_2003.mp4">

This links looks like to be ever the same format:
"http://download.ted.com/talks/"+talkDetails.mediaSlug+".mp4"

...and talkDetails.mediaSlug is found here:
<script type="text/javascript">var talkDetails = {"id":125,...,"mediaSlug":"JeffHawkins_2003",...}</script>

the url http://download.ted.com/talks/DanDennett_2003.mp4 woks...

But the interesting is this:
wget http://download.ted.com/talks/DanDennett_2003-480p-pt-br.mp4
the same download URL, plus quality and lang parameters is redirected to the right file.
And Works!

Stop here! The wget line above works! ^^^

but... How to find the direct URL?

On this TED talk:
http://www.ted.com/talks/jeff_hawkins_on_how_brain_science_will_change_computing.html

We open the download dialog with ajax generated window from:
http://www.ted.com/download/links/slug/JeffHawkins_2003/type/talks/ext/mp4

The URL looks like to be ever
"http://www.ted.com/download/links/slug/"+talkDetails.mediaSlug+"/type/talks/ext/mp4"

This "ajax page" shows the download URL template:
url = 'http://download.ted.com/talks/JeffHawkins_2003{quality}{lang}.mp4?apikey=TEDDOWNLOAD'

Where {quality} may be "-light", "-480p", "" (empty means regular),
and {lang} may be "" or "-"+langCode, where langCode = "en", "it", "pt-br", ...

...and works too.
