I am trying to stream a 6 channel wav file using testOnDemandRTSPServer
application with some changes in WAVAudioMediaFileSource.cpp to handle
multichannel file. Ijust want to know in payload type format , what value
should i use instead of 10 or 11 which are user for single or dual channel
file streaming.

Re: If VLC can play the file, you might try to use VLC as an RTSP server
and openRTSP (with -V) and see how VLC creates the SDP.  You might also try
asking on the VLC mail list.
In RFC 1889 (RTP/RTCP http://tools.ietf.org/html/rfc1889), page 10
references a side document for information on payload type. Here is a PDF
link that I found; the link in the RFC is broken:
http://www.potaroo.net/cgi-bin/id2pdf?f1=draft%2dietf%2davt%2dprofile%2d06%2etxt
  found on http://www.potaroo.net/ietf/idref/draft-ietf-avt-profile/
 Page 14 of the PDF has a table with RTP payload types.  You could search
out the latest version of this document and see if your WAV even has a
payload type registered.
