Originally created by @hdclark on GitHub (Aug 3, 2011).

I also am not able to download any video that is available (or, as far as I can tell, also available) in WebM. After grabbing the latest version (2011.03.29) I had to change:

!/usr/bin/env python

!/usr/bin/env python2.7

to get the script to proceed beyond the 185th line. Beyond this, I am unable to download any html5 content. I am also unable to try specify any other (non-WebM) formats:

The same fate happens when trying to use philhag's fork, which apparently fixed the issue earlier ( https://github.com/rg3/youtube-dl/issues/108 ).

I tried to use youtube-dl just now and also had this error. Until last week I used the program without problems. I suspect that there were changes on Youtube, because the Firefox extension Easy Youtube Video Downloader also crashed; button disappeared. Must be a detail common to the two softwares.

Yeah, there was a Youtube change sometime within the past couple hours, actually. It also broke my Youtube without Flash auto greasemonkey script as well. Hope to see a new version soon :)

And as far as I can tell, it doesn't have anything to do with WebM videos, I think it's broken for all videos right now.

doorknob60: you're right, there are (as far as I can tell) no working videos, WebM or not.

A few hours ago the problem only existed for WebM videos.

For what it is worth, clicking on 'save as' under the www.youtube.com/html5 beta currently serves you a link to a Rick-Roll.

Yes, all youtube downloads were broken. Commit 0ac22e.. in my fork should fix it. Does it work for you?

phihag: Works for me too. I still get flv's when downloading, though, instead of WebM.

Is there any planned support for WebM format? (In other words: should I close this issue because it is out of the scope of youtube-dl?)

@hdclark webm should be supported, and it works for me. By default, youtube-dl should choose the best (highest-quality) format. Try -f 43 or -f 45:

youtube-dl -f 45 http://www.youtube.com/watch?v=rLxQiI8c1Bs

I'll add a fallback (-f 45,43) when I get to it - probably this weekend.
