+To stream over UDP to a remote endpoint:

+@example

+ffmpeg -i @var{input} -f @var{format} udp://@var{hostname}:@var{port}

+@end example

+

+To stream in mpegts format over UDP using 188 sized UDP packets, using a large input buffer:

+@example

+ffmpeg -i @var{input} -f mpegts udp://@var{hostname}:@var{port}?pkt_size=188&buffer_size=65535

+@end example
