You mean a QR code (or similar)?  Yes, certainly, but it will
not be a "live link" that you can click.  A player would have
to implement such a feature, and I'm not aware of any player
(software nor hardware) that does that.

The only thing you can do with a QR code is to scan it with a
smartphone (then your smartphone's browser will open the linked
web page), or -- if you want to open the webpage on your PC --
make a screen shot and feed it into an online decoder like
xing.org or webqr.com (there are hundreds like these).  There
are also browser plugins (for Firefox and Opera, maybe others,
too).

But all of that is not exactly what you want, according to
your description.  The only thing that comes close is the way
Youtube (and some other online video sites) embed links into
their videos, but these only work with Youtube's own player.
I don't think that there is any generic video software that
supports this.  ffmpeg certainly does not.
