That looks pretty much like a proof of concept to me, but I'm impressed

IANAL, but GPL and for-profit business are not mutually exclusive.

Their particular ffmpeg-JavaScript seems to be compiled as GPL, not
LGPL. That *may* have an impact on the license of the JavaScript that
uses it (i.e. in particular your application), but that's really too
complex for me.
