To me, it looks like the BSD 3-clause, a.k.a. "Modified BSD" license.
Several files in ffmpeg's source tree seem to carry this license.

According to gnu.org: Yes.

Good question. ffmpeg's LICENSE.md provides some license references,
but is probably not meant as a template for distribution with a binary,
and doesn't explicitly quote the BSD-licensed components. It does
mention all GPL-licensed components, bit I assume to raise awareness
for when ffmpeg is GPL and when it it LGPL - and what non-free means.
