rtmplite -- http://code.google.com/p/rtmplite/ -- can be used to
record Speex .flv audio and a/v files from Flash/Flex applets, and
ffmpeg can be used to extract the Speex audio from such files, which
can also be replayed on Flash.

Media Server. There is no tooling support.

> Subject: [Speex-dev] Creating Flash Files with Speex Encoded Audio
>
> Hello,
>
> According to Adobe's Flash Specification[1] and Adobe's Flv
Spec[2], Adobe SWF and FLV files can have Speex encoded audio which will be
decoded internally by Flash Player. Are there any authoring tools available to
construct such files?
>
> It seems that Adobe CS5 and the open source Flex project are not able to
include these types of files; they either fail, or convert the Speex audio to
another type before inclusion.

> Thanks.
