How did you stream this, and how can I reproduce the problem? Looks like
the streamer is using global headers, while the SDP does not contain them...

What are you using as a streaming server? Is it ffserver? Can you
try to store the audio and video in an avi file (instead of an mp4)
and see if it works better?

If you start the streamer first and the client in a second time, is
the client able to receive the video stream after printing some errors?
