Originally created by @googollee on GitHub (Jun 27, 2011).

I watch the Google I/O video and want to download "Writing Web Apps in Go" . But youtube-dl doesn't work:

$ youtube-dl --all-formats  "http://www.youtube.com/watch?v=-i0hat7pdpk" 
[youtube] Setting language
[youtube] -i0hat7pdpk: Downloading video webpage
[youtube] -i0hat7pdpk: Downloading video info webpage
[youtube] -i0hat7pdpk: Extracting video information
ERROR: unable to download video (format may not be available)

I sure the url can access from the browser and play the video. But seems something wrong when youtube-dl handles it.

Is there any way to fix it and download?

Thanks.

Cannot reproduce this, neither from Germany nor USA. By the way, there's no need to set --all-formats, youtube-dl picks the best format automatically.

It might have been a temporary fluke of youtube. Can you reproduce it now? From which country/AS?

It still can't work. I run it from linode VPS in Dallas, TX, USA.

Sorry, should've seen that earlier: You're running an old version of youtube-dl (the message format may not be available does not exist anymore). Since youtube often changes the way downloads work, you'll need the newest version. You can check with youtube-dl -v. It worked for me with 2011.02.25b (package in Debian unstable) and 2011.03.29 (current trunk).

If updating doesn't solve the problem, a pcap dump or the output of strace -s 2000 youtube-dl "http://www.youtube.com/watch?v=-i0hat7pdpk" (warning: long) would be extremely helpful.
Also, feel free to contact me in private via email, jabber (phihag@phihag.de), github or twitter (@phihag); and I can give you a private URL for that specific video.
