youtube-dl version 2013.11.17 fails

[khendr01]

Script fails the same on both Linux and Mac, both with and without http proxies (on both platforms). (So the http proxy isn't the issue.)

Command line evidence:

114 Penguin$ youtube-dl -U
youtube-dl is up-to-date (2013.11.17)

Running youtube-dl 'http://www.youtube.com/watch?v=_VyfE4lVqOY' works (youtube instead of YouTube).

This has been fixed in youtube-dl v2013.11.18, at least for YouTube. Type sudo youtube-dl -U to update.

Hmm. Thanks for the work-around.

The Domain Name System (DNS) is designed to be case insensitive. So any case for the machine name should work.

Can the youtube-dl team consider putting in a tolower() call for just the machine name part of the URL, so examples like I gave will work again?

Thanks,

We are well aware that DNS is case-insensitive. The problem is entirely unrelated to DNS. One can call youtube-dl
with a wide variety of arguments. For example, all of the following work:

https://www.youtube.com/watch?v=_VyfE4lVqOY
//youtube.com/watch?v=_VyfE4lVqOY
YouTube.com/watch?v=_VyfE4lVqOY
_VyfE4lVqOY
PLVyfE4lVqOY
ytsearch:Foo/Bar
ytfavs:
:tds

This matching can often be case-insensitive, but sometimes not (for example, we can detect whether something is a youtube video or a youtube playlist ID by looking at the first two characters). Therefore, I am not sure how we would be able to proceed. Feel free to propose a patch/pull though.
