However, downloading the -f 298 and -f 299 options (which are 60fps) results in this error:

youtube-dl -f 299

The way to work around it is to add a custom “accept” header, as follows:

youtube-dl -f 299 --add-header "accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8"

This header was just copied from the headers chrome/firefox send. It might me useful to make them default.

The download and name works fine for me with the current version of youtube-dl. I suspect that you are running an outdated version. What output do you get when you add the -v flag?

Oh, that was with version 2014.10.15. I upgraded to 2014.10.30 and it works out of the box now.
