|86||86||NB that if you are sending to UDP or what not, that a client may have to wait until the next i-frame to be able to start receiving the stream, so the GOP setting (-g) i-frame interval will have an effect on how quickly they can connect. Setting it to a lower number means it will use more bandwidth, but clients will be able to connectmore quickly (the default for x264 is 250--so for 30 fps that means an i-frame only once every 10 seconds or so). So it's a tradeoff if you adjust it. This does not affect actual latency (just connection time) since the client can still display frames very quickly after and once it has received its first i-frame. Also if you're using a lossy transport, like UDP, then an i-frame represents "the next change it will have to repair the stream" if there are problems from packet loss.
