[gst-devel] using ORC for g729 documentation

Hello,

some notes about the opensource g729-compatible codec (with gstreamer
elements) I posted some weeks ago on this mailing list.
First of all, I've seen, Laurent Glayal has posted another announcement
aboput a parallel project in the meanwhile.. I wonder if a join could be
possible.

By the way, reference code is _heavily_ unoptimized in many points,
especially in the arithmetic operations emulation (64 bits multiplication,
division, etc) which, I guess, aren't covered from any copyright nor
patents.

I'd like to rewrite those operations in an optimized way using ORC.
Unfortunately I wasn't able to find so much documentation about this
interesting project and, before starting "shooting in the dark", I'd like to
know where I could gather any additional information.

Thanks in advance to anybody who will save me from ignorance.

Regards,
Gibro Vacco
