return specific error when video blocked on copyright grounds (python lib)

[dattaz]

actually it's return a generic error : youtube_dl.utils.DownloadError (same as no internet connection for example)
it's will be useful to have a specific error, something like youtube_dl.utils.BlockedCopyright

Post an example URL, and how you are calling youtube-dl (ideally the minimum code to reproduce it)

code to reproduce https://gist.github.com/dattaz/80c94db5d22b2bb5b96f
url blocked in france..

Post the output of script execution.

1. In the future, please format your code to make sure it can be run without modifications (i had to remove the leading indentation).
2. If you are running on python 2.x you need to use from __future__ import unicode_literals(as reported when running the script).
3. You can access the original exception:

                       except youtube_dl.utils.DownloadError as e:
                           print(repr(e.exc_info[1]))

gives ExtractorError(u'...'), there are multiple causes for an ExtractorError. You can directly use it to report the problem.

sorry for indentation, i use python 2.x but no report about using from future import unicode_literals

can we know all cause for ExtractorError ? because other url (also blocked) show a different message...that why i think having a specific error can be a good idea

[jaimeMF]

There are a lot of possible error messages (georestriction, removed due to copyright, removed by the user, temporary problems ...). I don't think we can accurately classify them. As I said if you get the original exception, you can get the YouTube said: This video is available in France, French Guiana, Guadeloupe, Martinique, New Caledonia, French Polynesia, Saint Pierre and Miquelon, Réunion, Wallis and Futuna, Mayotte only message.
