OMGosh dude, you are difficult.
How do you propose we certify it? Do a careful combing-over of the source
code, or what?
VLC is already under a Free license, the source code can be obtained, and
it's popularly recognized as Free (so it gets included in repositories of
systems that carefully separate free and nonfree software, like Debian and
Fedora). All those factors alone make it VERY close to certain that the
software is indeed Free. Ditto the Opus codec. I would be astonished if
either one turned out to be proprietary.
So yeah, please make like a Wikipedian and Assume Good Faith.
