No, this isn't an issue for us, as we're simply unwrapping the existing aac encode from inside the flash wrapper, and re-wrapping it as an mp4/m4a file. We don't actually make the aac itself. If you look at the output from "ffmpeg -formats", the important lines will be:

 E mp4             MP4 format
DE flv             FLV format

This means it can encode the mp4 format, and both decode and encode Flash (we care about decoding only).
