Flash / Flex Speex audio decodes to play speex file

Question

I want to play * .spx files that are Speex encoded on the Internet.
But I do not know Flash / Flex or any Flash Audio codec. After a Google search for the whole day, I got some solutions, that is:

• Do something wrapping the Speex files with the FLV container, because Speex only plays as the audio codec in the FLV container.
  Now I can play the SPX-Audio-Only FLV file in Flex, I use netStream.play("audio-only-speex.flv"), but I don’t know how to wrap the Spx file with the FLV container using ActionScript.
  Any project project?

• Spx decoding using AS.
  I checked the fllowing pages that they all decrypted OGG Vorbis but not Speex :(

  Adobe also provides the AS3 OggVorbis library, which is ported to Alchemy:

• FMS: Stream the server using FMS or Red / Xuggle. I’ve never heard of FMS stuff before, and also not sure if my virtual host supports it or not ...

• Convert all Spx files to MP3.

I think the best solution is Spx decoding in AS3, yes, I would like to make Flash Player Flash.
