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 or remultiplexing. it does not stream from plain files, only DVB devices. If you were looking for these features, switch to VLC.

OPTIONS

-a, --adapter <adapter>
Address of the adapter
-A, --asi-adapter
Read packets from an ASI adapter (0-n). If support for Deltacast ASI cards is compiled in, prefix the adapter number with "deltacast:" to select a Deltacast input. Deltacast inputs are numbered as (100 * card number) + channel number.
-b, --bandwidth <bandwidth>
Frontend bandwidth
-B, --provider-name <name>
Service provider name to declare in the SDT. If you want to change provider name per output use /srvprovider= output option in the config file.
-c, --config-file <config file>
Use the given configuration file
-C, --dvb-compliance
Pass through or build the mandatory DVB tables
-d, --duplicate <dest IP:port>
Duplicate all received packets to a given destination
-D, --rtp-input
Read packets from a multicast address instead of a DVB card
-W, --emm-passthrough
Enable EMM pass through (CA system data)
-Y, --ecm-passthrough
Enable ECM pass through (CA program data)
-e, --epg-passthrough
Enable EPG pass through (EIT data)
-E, --retention <retention>
Maximum retention allowed between input and output (default: 40 ms)
-f, --frequency <frequency>
Frontend frequency. If '-' is specified instead of a numeric value, the frontend will be not be tuned by dvblast and you should use external tuning tool (szap) to tune it.
-F, --fec-inner <FEC>
Forward Error Correction used by satellite (FEC Inner)
DVB-S2 0|12|23|34|35|56|78|89|910|999 (default auto: 999)
-G, --guard <interval>
DVB-T guard interval
DVB-T 32 (1/32)|16 (1/16)|8 (1/8)|4 (1/4)|-1 (auto, default)
-h, --help
Print the help message
-H, --hierarchy <hierarchy>
DVB-T hierarchy (0, 1, 2, 4 or -1 auto, default)
-i, --priority <RT priority>
Real time priority
-I, --inversion <inversion>
Inversion (-1 auto, 0 off, 1 on)
-j, --system-charset <charset>
Character set used for printing messages (default UTF-8)
-J, --dvb-charset <charset>
Character set used in output DVB tables (default ISO-8859-1)
-k, --uncommitted <uncommitted port>
Port number for uncommitted diseqc (0: no uncommitted diseqc, 1-4)
-K, --fec-lp
DVB-T low priority FEC (default auto)
-1, --delsys <delivery_system>
Select delivery system. Possible values: DVBS|DVBS2|DVBC_ANNEX_A|DVBT|ATSC (default guessed)
-5, --multistream-id <stream_id>
Set stream ID for multistream capable transponders. Value: 0-255 (default: 0)
-l, --logger
Send messages to syslog instead of stderr
-g, --logger-ident <logger_ident>
Set the program name that will appear in syslog (default: dvblast /the executable name/).
-L, --latency <latency>
Maximum latency allowed between input and output (default: 100 ms)
-m, --modulation
Modulation
DVB-C qpsk|qam_16|qam_32|qam_64|qam_128|qam_256 (default qam_auto)
DVB-T qam_16|qam_32|qam_64|qam_128|qam_256 (default qam_auto)
DVB-S2 qpsk|psk_8 (default legacy DVB-S)
-M, --network-name <name>
DVB network name to declare in the NIT
-n, --frontend-number <frontend number>
The frontend number
-y, --ca-number <ca_dev_number>
CA device number. Default: 0
-2, --dvr-buf-size <size>
Sets the size of the DVR TS buffer in bytes.
-N, --network-id <ID>
DVB network ID to declare in the NIT
-o, --rtp-output <SSRC IP>
RTP output IP
-O, --lock-timeout <timeout>
Timeout for the lock operation (in ms)
-p, --force-pulse
Force 22kHz pulses for high-band selection (DVB-S)
-P, --pilot
DVB-S2 Pilot (-1 auto, 0 off, 1 on)
-q, --quiet
Be quiet (less verbosity, repeat or use number for even quieter)
-Q, --quit-timeout <delay>
When locked, quit after this delay (in ms), or after the first lock timeout
-r, --remote-socket <remote socket>
Remote socket to use
-R, --rolloff <rolloff>
Rolloff value to use
DVB-S2 35=0.35|25=0.25|20=0.20|0=AUTO (default: 35)
-s, --symbol-rate <symbol rate>
Symbole rate
-S, --diseqc <diseqc>
Satellite number for diseqc (0: no diseqc, 1-4, A or B)
-t, --ttl <ttl>
Time-To-Live of the multicast stream
-T, --unique-ts-id
Generate unique TS ID for each program
-u, --budget-mode

-U, --udp
Use raw UDP rather than RTP (required by some IPTV set top boxes)
-v, --voltage <0|13|18>
Voltage to apply to the LNB (QPSK)
-V, --version
Only display the version
-w, --select-pmts
Set a PID filter on all PMTs. This option is automatically enabled when config file is used. To disable setting PMT filters in case of config file is used, add --select-pmts after --config-file <file> parameter.
