Hi everybody<br>
<br>
I've found a project quite similar to yours encoding h264 and
streaming via wifi, it also cover how to adjust bitrate depending on
the bandwidth.<br>
<br>

<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 style="FONT-STYLE: normal; DISPLAY: inline; FONT-FAMILY:

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>
