screencast.com support

[Nikoli]

Please add support for http://screencast.com/

[phihag]

Please read our guide for bug reporting. In particular, we need an example URL - http://screencast.com/ does not show any videos for me.

[Nikoli]

https://encrypted.google.com/search?q=site:screencast.com finds a lot videos, from first page of results:
http://www.screencast.com/t/3ZEjQXlT
http://www.screencast.com/t/OWUxZGMxN

Thank you for the report. youtube-dl 2014.07.11.2 and newer now include support for screencast. Type youtube-dl -U to update.

I've tested this with these two URLs, but feel free to report more - there may be more than one video type.

Thank you for adding support so fast, but a lot urls do not work:

These random videos from site:screencast.com, most of them do not work:
http://www.screencast.com/t/aAB3iowa
http://www.screencast.com/t/ee7qBLFUBv
http://www.screencast.com/t/BrlWxmckTd3
http://www.screencast.com/t/tH7VyaR9

[phihag]

See? Now you know why site support request should include example URLs :)

youtube-dl 2014.07.11.3 adds support for all of these screencast.com videos with the exception of http://www.screencast.com/t/tH7VyaR9, which is not a video, but an SWF presentation.
