I really doubt this other implementation is worth bothering with,
except maybe to lift a few optimized functions. Porting external code
into lavc results in lots of bloat and code duplication, since the
toolkit of dsp functions already in lavc won't get used. I expect the
lavc encoder just needs some optimization, and then it will be
perfectly fine on its own.
