Compile the -program with `make`. - - -The socket description format -============================= - -For conveniency all tools use the same way of describing a socket in a -program argument: - -<connect address>:<connect port>@<bind address>:<bind port> - -All parts are optional; default port (1234) or wildcard address will then -be used. - -Some examples: - -Reading all streams coming to port 5004: - @:5004 -Reading from a multicast stream on port 5004: - @239.255.0.1:5004 -The same, with source-specific multicast: - 192.168.0.1@239.255.0.1:5004 -Writing to a multicast stream on port 5004: - 239.255.0.1:5004 -The same, but binding to a specific interface: - 239.255.0.1:5004@192.168.0.2 - - -Using Multicat -============== - -Recording a multicast address to a file: - -multicat @239.255.0.1:5004 /tmp/myfile.ts - -This will also create file /tmp/myfile.aux. Playing back the file: - -multicat -p 68 /tmp/myfile.ts 239.255.0.2:5004 - -Adding an RTP header to an existing multicast stream: - -multicat -p 68 -u @239.255.0.1:5004 239.255.0.2:5004 - -The PCR PID is here supposed to be 68. If you don't specify it, the timestamps -will not be RFC-compliant (but will work in most cases). You can use the -get_pcr_pid tool from libdvbpsi to determine it. Otherwise, if you are sure -the stream contains a single program, and only one PID carries a PCR, you can -pass "-p 8192" the disable the PID check. This isn't on by default because -it can produce awful things with multi-program transport streams, and the -world would be a better place if people had to knowingly turn it on. - - -Using IngesTS -============= - -ingests -p 68 /tmp/afile.ts - -This will create file /tmp/afile.aux. 68 is supposed to be the PCR PID. -The same note as above applies to ingesTS. - -Playing the file: - -multicat -p 68 /tmp/afile.ts 239.255.0.2:5004 - - -Using OffseTS -============= - -We want to take the first 60 minutes of a TS file. We must scale it in a -27 MHz clock: -60 * 60 (seconds) * 27000000 (MHz) = 97200000000 - -Find the offset in 1316-blocks: - -offsets /tmp/myfile.aux 97200000000 - -It returns for instance "556896".
