Yes, no fate vector indeed. I didn't look up any vector that may have
been provided by a standardization body.

Same here, even using files I think encoded by either Quicktime or Nero.

Indeed, it's just that it was part of the dsp functions, and I
implemented before seeing it wasn't used. And so, it isn't validated
either.

So indeed, the patch is unneeded, as well as dsp implementations of
this function.
