The name could also be simply libsvtav1, same as the library (and the
configure option), since unlike libvpx and (in theory) libaom, no other
codec will be supported by it. HEVC is in a different library.

LGTM either way.

As for options, most of FFmpeg uses underscores. It would be better to
use them too here.

Also, you cannot rename options, you have to create aliases and
deprecate the original. Otherwise you break user cases.

This encoder was pushed yesterday night, which is why this change is
being suggested. It's not going to break anyone's use cases.

Yes, I realized that afterwards and forgot to amend.

But options with underscores are still the preferred form in the
project.

That makes more sense.  I'll use libsvtav1 everywhere.

... and we are never going to achieve consistency by inheriting options with dashes in the name of backward compatibility.  Fair.

New version to follow.
