I'm not totally certain, but your problem is likely due to appending SPS/PPS
information to _every_ intra-frame. I would correctly send it in your SDP
file, and never send it in-stream; this will resolve the issue. (To test
this hypothesis, try sending it with only the first intra-frame) <o:p></o:p></span></font></p>
