Assuming you mean the fifo_size parameter for the udp protocol:



   options contains a list of &-separated options of the form key=val."

$ ffmpeg -i input -f mpegts udp://hostname:port?fifo_size=25000000

The default value is listed below in the documentation as 7*4096 = 28672
packets of size 188 (= 5390336 bytes).

You weren't precise enough about what you are trying to do and what
your issue is.
