Hi everybody
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.

Hi Ross,
Now we are able to stream over Wifi with receiver application running
on iOS device.
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.
We had calculated the time needed for capture and H264 encode the
frame which is always lesser than the frame rate (33ms for 30fps)
Trying to find where the delay is, Server side or the receiver side.
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?
Please suggest any other areas which can cause the propagation delay?
Thanks in advance.
Regards,
Ashfaque

It 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.
