I understand that openRTSP can recieve unsupported RTP data using -s
opitions.

I'm trying to recieve a stream of JEPG data reflected by Darwin Streaming
Server using openRTSP.when i run i get something like this..

C:\live\testProgs>openRTSP rtsp://128.82.x.xx/odu.sdp
Opened URL "rtsp://128.82.x.xx/odu.sdp", returning a SDP description:
v=0
o=ApplicationCaster 46475841112261 3301404135 IN IP4 128.82.5.57
s=\odu.sdp
c=IN IP4 0.0.0.0
t=0 0
a=control:*
m=application 0 RTP/AVP 96
a=rtpmap:96 JPEG/90000
a=control:trackid=1

Created receiver for "application/JPEG" subsession (client ports 2944-2945)
Setup "application/JPEG" subsession (client ports 2944-2945)
Created output file: "application-JPEG-1"
Started playing session
Receiving streamed data...

even tough it creates a file by name application-JPEG-1 in the testProgs
folder it doesnt write anything into it.

The header of RTP stream which openRTSP is currently trying to recieve is
something like this...

RTP packet length=1462

v=2 p=0 x=0 cc=0 m=0 pt=97 seq=1 ts=472998495 ssrc=0xffd8ffe0

documentation states -s <byte-offset> specifies the size (in bytes) of any
special header that follows the standard RTP header,the RTP packets
doesn't have any special header followed by RTP header,how do i recieve it
using openRTSP.
