Inputs and +outputs can be network streams (unicast and multicast), files, character +devices or FIFOs. + +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 +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. + +IngesTS is a companion application designed to manipulate TS files. It +reads the PCR values of the file, and builds the auxiliary file that is +necessary for multicat. + +OffseTS is another companion application to manipulate auxiliary files. +Given an offset in time from the beginning of the file, it returns the offset +of the position in number of packets. + +Finally aggregaRTP and desaggregaRTP can be used to carry a high-bitrate +signal over several contribution links. + +The multicat suite of applications is very lightweight and designed to +operate in tight environments. Memory and CPU usages are kept to a minimum, +and they feature only one thread of execution. They have no dependancy. + +-- +Meuuh 2010-01-07 |
