How do I download a video from Vimeo with youtube-dl embedded in Python? It works from the command line:

youtube-dl https://vimeo.com/15991774

(works)

and it works from Python if it is the first video I download:

import youtube_dl
ydl = youtube_dl.YoutubeDL({})
ydl.download(["https://vimeo.com/15991774"])

(works)

However, it does not work after downloading a video from Youtube:

ydl.download(["https://www.youtube.com/watch?v=RwdY7Eqyguo"])

(works)

ydl.download(["https://vimeo.com/15991774"])

does not work:

[vimeo] 15991774: Downloading webpage
[vimeo] 15991774: Extracting information
[vimeo] 15991774: Downloading webpage

Post complete code. Post complete verbose log.

The code was complete. Here it is again:

#!/usr/bin/env python3

import youtube_dl

ydl = youtube_dl.YoutubeDL({"verbose": True})
ydl.download(["https://www.youtube.com/watch?v=RwdY7Eqyguo"])
ydl.download(["https://vimeo.com/15991774"])

And here is the complete output:
