requesting a MPEG TS format through RTSP

[supriyas]

Hi,
Through RTP it is possible to play a file in TS format through strem output options.This doesnt distinguish between the audio and video packets and shows single SSRC for all packets. I want such behaviour(no difference in audio and video ) through RTSP.Is it possible? Is TS muxer useful for RTSP.HOw can I stream a TS file through RTSP?
Please help,
Thanks in Advance,
