I updated my (latest) macOS system to the latest brew version of youtube-dl and tried to download a facebook developer video (url copied from FB video playback & right-click on "Show video URL".

Here is the output from the command line run with --verbose:

youtube-dl --verbose https://developers.facebook.com/FacebookforDevelopers/videos/10154614514323553/

If I try to download that URL directly in the browser address bar (Chrome/latest) I get an error from FB:

Sorry, the link you followed may be broken, or the page may have been removed.
Search for FacebookforDevelopers videos 10154614514323553 on developers.facebook.com

I'm not sure if this problem is with youtube-dl or FB itself. It is odd that the URL they explicitly give you is broken...

Anyway, filing this here just for your info. Let me know if there is any more debugging I can help with.
