[mary-users] Mary and Flex, commit input w/o Socket shutdown

[René Bühling]

Hello Marc,

thank you very much for your valuable hint which lead me to a working 
version.

Indeed it is now working with MARY 4 via a HTTP connection. Would that 
HTTP communication have worked with Mary 3.6 too? I could reach the 3.6 
server via http but I did not manage to send the arguments, it always 
says "Error parsing request: Expected either a line MARY IN=<INPUTTYPE> 
OUT=<OUTPUTTYPE> [AUDIO=<AUDIOTYPE>] or a line containing only a number 
identifying a request."

Anyway, I feel that I would prefer the version 4, but the major problem 
is currently that Mary 4 seems no longer to be able to produce MP3s. 
Flash on the other hand is not able to play WAVs. I found workaround 
ActionScript classes which manage to play the WAV received from Mary at 
all, but there is something wrong with the playback speed or else. The 
received audio clip is played extremely slow. Has the MP3 support gone 
or will it reappear in a future realease of Mary? Or can it even be 
reactivated via config?

Thanks,
René
