Hamac example gives subprocess error

Using the code from the example on the blog (python 2.7)

[MoviePy] Running:

youtube-dl NpxD9TZIlv8 -o hamac.mp4Traceback (most recent call last):

You must install youtube-dl to be able to use download_webfile()

@Zulko thanks! Isn't that module imported in moviepy? Why is there no missing module error thrown?

[Zulko]

For the moment I don't use the module, I use the terminal interface of youtube-dl, which is why what you see is an OSError from the terminal. In the current version on Github, that error is caught and you get a nicer message saying that you must install youtube-dl.
