Verify in what sense? This might verify not that it's an MPEG2-layer 3
compliant bitstream, but only whether mpg123 will barf. Sure, it'll work
for purposes intended most times, but I don't recall if mpg123 has been
certified itself.
On a related note to the Vorbis thread, I know the gentleman at AT&T
Research who spent 14 years becoming the "inventor" of the mpeg encoders.
The patents are AT&T's shared with Fraunhofer, but Johnston's opinion is
that Vorbis is going to have a very tricky time skirting the issue of
patent infringement if they do have anything that works. I think the
magnitude of the project is generally unappreciated, perhaps even by
Vorbis. AT&T has 14 years of lawyers patenting JJ's every move,
good or bad.
(Disclaimer -- I don't like lawyers, these sorts of patent deals, and I
have no preference one way or the other as to encoders. Perceptual coding
is an interest, but it's not how I want to *listen* to my music! <g>)
