FFmpeg is driven by the decoding loop, so either your system buffer the
network packet for you or you'll read them longer past their arrival
depending on what ffmpeg is doing (e.g. it got enough data to decode
while probing so it won't check for it for a while).

Are you 100% sure it is working as should? try to write a small program
that fetches from udp and feeds to a file and then inspect the resulting
dump and then feed it to ffmpeg from a pipe
