Re: Need for help about using vorbis in embedded system

Thank you for replying.
i would like to add another question.what is the output(as data structure) that is expected from the vorbis?,can i get the output in a segmented form that is suitable for packetizing(in arrays or buffer data structures) at a sender-side, and reassembling at a receiver-side?
note: i am using iMote2 sensor node with PXA271/XScale processor of ARM architecture,TinyOS operating system,and C with nesC programming languages.


sorry for asking much

Regards,
Mash'al

Yes, the reference encoder should work in realtime on a system like
that. Note that's it's not especially well-tuned for 8 kHz audio; most
people use it at 48 or 44.1 kHz. It will work though.

You might also be interested in the new Opus codec we're developing.
It's somewhat higher complexity, but offers superiour compression and
the reference implementation includes a fixed-point encoder, which may
make up for the complexity difference on XScale.
