multicat - Multicast equivalent of Netcat SYNOPSIS
multicat [-i <RT priority>] [-t <ttl>] [-p <PCR PID>] [-s <chunks>] [-n <chunks>] [-d <time>] [-a] [-S <SSRC IP>] [-u] [-U] [-m <payload size>] <input item> <output item> DESCRIPTION
Multicat is a 1 input/1 output application. Inputs and outputs can be network streams (unicast and multicast), files, 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 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. ITEMS
Item format <file path | device path | FIFO path | network host> Host format [<connect addr>[:<connect port>]][@[<bind addr][:<bind port>]] OPTIONS
-a Append to existing destination file (risky) -d <time> Exit after a definite time (in 27 MHz units) -i <RT priority> Real time priority -h Show summary of options -m <payload size> Size of the payload chunk, excluding optional RTP header (default 1316) -n <chunks> Exit after playing N chunks of payload -p <PCR PID> PCR PID -s <chunks> Skip the first N chunks of payload -S <SSRC IP> Overwrite or create RTP SSRC -t <ttl> TTL of the packets send by multicat -u Source has no RTP header -U Destination has no RTP header SEE ALSO

DVBlast - Simple and powerful dvb streaming application SYNOPSIS
dvblast [-q] [-c <config_file>] [-r <remote_socket>] [-t <ttl>] [-o <SSRC_IP>] [-i <RT_priority>] [-a <adapter>] [-n <frontend_number>] [-S <diseqc>] [-f <frequency>] [-D <src_host>[:<src_port>][[@<src_mcast>][:<port>]][/<opts>]] [-A <ASI_adapter>] [-s <symbol_rate>] [-v <0|13|18>] [-p] [-b <bandwidth>] [-I <inversion>] [-F <fec_inner>] [-m <modulation>] [-R <rolloff>] [-P <pilot>] [-K <fec_lp>] [-G <guard_interval>] [-H <hierarchy>] [-X <transmission>] [-O <lock_timeout>] [-u] [-w] [-U] [-L <latency>] [-E <retention>] [-d <dest_IP>[<:port>][/<opts>]] [-z] [-C] [-e] [-M <network_name>] [-N <network_ID>] [-T] [-j <system_charset>] [-W] [-Y] [-l] [-g <logger ident>] [-Z <mrtg_file>] [-V] [-h] [-J <DVB_charset>] [-B <provider_name>] [-Q <quit_timeout>] [-x <text|xml>] DESCRIPTION
DVBlast is a simple and powerful streaming application based on the linux-dvb API. It opens a DVB device, tunes it, places PID filters, configures a CAM module, and demultiplexes the packets to several RTP outputs. DVBlast is designed to be the core of a custom IRD or CID, based on a PC with Linux-supported DVB cards. DVBlast does not do any kind of processing on the elementary streams, such as transcoding, PID remapping or remultiplexing. it does not stream from plain files, only DVB devices. If you were looking for these features, switch to VLC. OPTIONS
