Watch later feed url is interpreted as a video (was: ytwatchlater extractor doesn't work for youtube watch-later page.)

[ffernand]

I've tried downloading the list of videos from the watch-later section of youtube. The following command is what I've tried (minus credentials)

youtube-dl --verbose -cit -u [EMAILADDRESS] -p [PASSWORD] ytwatchlater

... producing the following output:

    raise ExtractorError(u'YouTube said: %s' % video_info['reason'][0], expected=True)

I've also tried using the full url

youtube-dl --verbose -cit -u [EMAILADDRESS] -p [PASSWORD] https://www.youtube.com/feed/watch_later

Which equally doesn't work but produced a different stack-trace...

The following is version info...

$ youtube-dl -U
youtube-dl is up-to-date (2013.08.17)

Only [EMAILADDRESS] AND [PASSWORD] in output were changed to protect the innocent ;)

You have to call it with :ytwatchlater, like youtube-dl :ytwatchlater -u ... -p ..., this is done so that it's not interpreted as a Youtube video id.
The second error is a bug, because it's interpreted as a youtube video url, with id feed.

You can use --netrc and the ~/.netrc file to hide the login information and to save time typing it.

Ahh, ok! Feeling sheepish... much appreciated!!!

We have to fix the https://www.youtube.com/feed/watch_later being interpreted as a video.
