[Live-devel] MRCP over RTSP with "liveMedia" library

[David Guthrie]

I implemented much of the MRCP protocol last year using the live  
media library.  If you want to talk with me offline, I can work out a  
way to get the code I was writing to you.  It was, of course, an  
older version of liveMedia, so you'd have to apply the patch to a new  
version of live.  I also only implemented sending data upstream to do  
voice recognition.  I tested against Nuance MRCP server 1.0.
