Hi all!

I have a mobile app that streams a H.263 / RTP / UDP stream to my wowza server. I configured the stream using a simple .sdp file:

=0

o=- 0 0 IN IP4 127.0.0.1

s=Unnamed

i=N/A

c=IN IP4 0.0.0.0

t=0 0

a=recvonly

m=video 20030 RTP/AVP 96

a=rtpmap:96 H263-1998/90000

a=control:trackID=0

I can read the stream really well with VLC, but can’t read it with quicktime or real - I’m just getting a blank screen.

Anyone has had a similar problem? Any idea how to solve this? Thanks!!!
