New error on some videos

[benoon]

Anyone know what error is that ?
It happens from time to time for some videos.

Example:

./youtube-dl http://www.youtube.com/watch?v=ahekmrIM-Sw
[youtube] Setting language
[youtube] ahekmrIM-Sw: Downloading video webpage
[youtube] ahekmrIM-Sw: Downloading video info webpage
[youtube] ahekmrIM-Sw: Extracting video information
Traceback (most recent call last):
File "./youtube-dl", line 3017, in
retcode = fd.download(all_urls)
File "./youtube-dl", line 609, in download
ie.extract(url)
File "./youtube-dl", line 852, in extract
return self._real_extract(url)
File "./youtube-dl", line 1115, in _real_extract
url_map = dict((ud['itag'], urllib.unquote(ud['url']) + '&signature=' + ud['sig']) for ud in url_data)
File "./youtube-dl", line 1115, in
url_map = dict((ud['itag'], urllib.unquote(ud['url']) + '&signature=' + ud['sig']) for ud in url_data)
KeyError: 'url'

Here another example video which gives the same: http://www.youtube.com/watch?v=7prEbLsc_r4

Seems these both are RTMP videos, though they fail to download for me. Except I get a proper error though, instead of making Python crash like it does for you. Are you using the latest version?

Also, do you have rtmpdump installed? I don't know if it's related, but you need it to be able to download those kind of videos. Regardless though, I think RTMP downloading is still broken, which is unfortunately an issue related to rtmpdump which doesn't support the protocol used by YouTube.

Still, you should get a proper error when you try, instead of Python complaining like that. As I said, can you check that you have the latest version of youtube-dl?

a bit delayed response :), was out longer time...
no, i was not using the latest ver.

i have rtmpdump installed but it seems not to work for me.
do you know any other possibilites than yt-dl to get rtmp videos from yt?

Weird that you're getting these errors, then. Anyway, on Linux I don't think there's any tool to get videos through RTMP with the new protocol: rtmpdump is as far as I know the most advanced tool for that and doesn't support it.

You may have some luck with some tools on Windows, but even then I wouldn't bet on it too much. I suppose the point of using RTMP is to prevent people from downloading entire movies like that. Or maybe it's just more convenient for them. Either way I don't think there's a way to download them as of now, sorry. I could very well be wrong though, someone else may have an idea.
