<DIV>Hi Ross, </DIV>
<DIV> </DIV>
<DIV>Now we are able to stream over Wifi with receiver application running on
iOS device.</DIV>
<DIV>But we are getting a very large propagation delay ranging from 200ms
initially when application to more than 1.5 sec after some 5-10 minutes
duration. We are using a camera which produces 30fps.</DIV>
<DIV>We had calculated the time needed for capture and H264 encode the frame
which is always lesser than the frame rate (33ms for 30fps)</DIV>
<DIV>Trying to find where the delay is, Server side or the receiver side.</DIV>
<DIV> </DIV>
<DIV>Does live555 internal layer waits until the frames arrive in time order (As
fPresentationTime is used for each frame), or can we drop frames if they are not
in order? Can this help us to overcome the issue of propagation delay?</DIV>
<DIV> </DIV>
<DIV>Please suggest any other areas which can cause the propagation delay?</DIV>
<DIV> </DIV>
<DIV>Thanks in advance.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV>Ashfaque</DIV>

looks to me like your output data rate exceeds the capacity of your network (in
this case, a WiFi network). This is especially likely if you are streaming
via multicast, because the bandwidth of multicast over WiFi tends to be
significantly lower than unicast. If you are streaming via multicast, then
you might want to try streaming via unicast instead.<BR><BR>
