multicat - Multicast equivalent of Netcat
Contents
Description
Multicat is a 1 input/1 output application. Inputs and outputs can be network streams (unicast and
multicast, IPv4 and IPv6), files, directories, character devices or FIFOs. It is thought to be a
multicast equivalent of the popular netcat tool.
Multicat tries to rebuild the internal clock of the input stream; but it wants to remain agnostic of what
is transported, so in case of files and directories, the said clock is stored to an auxiliary file
(example.aux accompanies example.ts) while recording. Other inputs are considered "live", and the input
clock is simply derived from the reception time of the packets.
