Config file syntax for site specific parameters?

[pps]

I just added
-f 299+bestaudio/137+bestaudio/298+bestaudio/bestvideo+bestaudio
to the youtube-dl config file at
~/.config/youtube-dl/config
to specify which youtube video sizes I prefer.

Problem is, when I now try to use youtube-dl to download files from vimeo, that download now fails. ("ERROR: requested format not available").

Is there a syntax for the config file so that we can specify certain video sizes for youtube but keep the default behavior for other sites?

Thank you!

Simply add /best at the end (-f 299+bestaudio/137+bestaudio/298+bestaudio/bestvideo+bestaudio/best) it will fallback to the default format.
I'm closing the issue, since I think that should work. Please comment here if it doesn't solve your problem.

There's already a proposal for supporting per site configuration: #3101.

It works, thanks!
