I am not aware of additions that are missing. The official mpg123
contains a load of bugfixes and enhancements, compared to the version
the MPlayer mp3lib is derived from.
We did port the 32bit SSE and 3DNowExt optimizations from MPlayer.
Is there something I overlooked in particular?

I am not familiar with ffmpeg code and what synergies it might bring.
Perhaps it would make sense... or perhaps it would also make sense to
just make ffmpeg use libmpg123 for fast floating point decoding (did you
mean that?). I already thought about adding libmpg123 support to
libsndfile, for example -- not everyone needs to use the specific
features of libmpg123.
One argument against just merging with ffmpeg may be that a standalone
library for "just" MPEG audio has its uses and may be easier to port to
something like the Sony PSP (which happened) or some DSP chip (which
happened, too;-).


Alrighty then,

Thomas.
