[Seshu kumar Chava]

Hi Ross,
 
     I am using windows media player for playing this file, even winamp
also giving error while trying to play this file. 
     I was able to play the mp3 with out any problems after receiving
over RTP but for wave files I am facing problem.
 
Can you please help me in this regard.
 
Thanks,
Seshu.

What media player were you using?  You should be able to play the stream

using QuickTime Player, or VLC, or (I think) MPlayer.

I'm sorry, but I don't understand what you're saying here.  If the input

file contains 16-bits-per-sample audio data, then the data will be
streamed 
- in RTP - as the "audio/L16" MIME type (i.e., 16-bit data).  Similarly,
if 
the input file contains 8-bits-per-sample audio data, then the data will
be 
streamed - in RTP - as the "audio/L8" MIME type (i.e., 8-bit data).
 
If you want 16-bit input data to be converted to 8-bit u-law for
streaming, 
then you can do so by setting the variable "convertToULaw" to "True" in 
"testOnDemandRTSPServer.cpp".
