best (legal) way to record/convert audio

hi,

i'm developing an application that i hope to offer commercially.

i'm interested in finding the best (and least expensive) *legal* method for recording audio using flash media server 3 (whatever version) and then converting it to WAV (e.g., 8kHz, 8-bit mulaw) or a similar format.

i have found a program called ffmpeg, which works very nicely. however, i can not find info on whether this is a legal method for decoding audio in a .flv file for use in a commercial application. (i plan to manipulate the audio on the server side, then stream the result back in mp3 format or something similar.)

are there features in the latest flash clients that i can take advantage of in order to eliminate (or reduce) any license fees? (i can force clients to upgrade their flash clients if necessary.) if not, what company do i have to deal with for licensing, and what's the best approach?

any advice would be greatly appreciated.

tom

    Recorded audio stream is encoded by Nellymoser proprietary codec. The
    only legal way to decode it is to buy Nellymoser ASAO SDK. It's worth
    of doing if your estimated income from this project will be around $1M
    or so :)

    See above. And FFMPEG has appropriate disclaimer at its homepage. It's
    very dificult to miss it out...
