Embedding youtube-dl: no suitable InfoExtractor

[ghost]

I tried the example for embedding youtube-dl but I always get this error:

ERROR: no suitable InfoExtractor: http://www.youtube.com/watch?v=BaW_jenozKc

Could you post the code you are using for calling youtube-dl and the version?
If you are using the code from https://github.com/rg3/youtube-dl/blob/master/README.md#embedding-youtube-dl, you may be using a version too old.

I used that code from https://github.com/rg3/youtube-dl/blob/master/README.md#embedding-youtube-dl. My version : 2015.01.23.4

Ok, what's the output you get if you run these two commands in the python interpreter (you have to run python):

>>> import youtube_dl
>>> youtube_dl.version.__version__

Thank You. You were right.
The command-line programm was version 2015.01.23.4, but the python package was an old one.

I'm closing the issue then. If you have any other problem, feel free to open a new issue.
