dvbv5-zap(1) User Commands dvbv5-zap(1)NAMEdvbv5-zap - DVBv5 tool for service tuning
SYNOPSISdvbv5-zap [OPTION]... channel-name
dvbv5-zap [OPTION]... frequency-name (for monitor or all PIDs mode)
DESCRIPTIONdvbv5-zap is a command line tuning tool for digital TV services that is
compliant with version 5 of the DVB API, and backward compatible with
the older v3 DVB API.
dvbv5-zap uses by default a new channel/service file format that it is
capable of supporting all types of Digital TV standards. It can also
support the legacy format used by the legacy dvb-apps.
The dvbv5-zap tool can be used on several different modes, depending on
the parameters used.
Please note that, in order to be able to use it in record mode, where
both the audio and video Packet IDs (PIDs) are output to a dvr record
node, the input file should contain the PIDs, e. g. they should have
been produced by a digital TV zap application like dvbv5-zap.
OPTIONS-c, --channels= channel-name-file
Read channels list from 'file'. Defaults to ~/.tzap/chan‐
nels.conf.
-3, --dvbv3
Force dvbv5-zap to use DVBv3 only. Useful to test if the legacy
API support is working.
-a, --adapter=adapter#
Use the given adapter. Default value: 0.
-A, --audio_pid=audio_pid#
Select a different audio Packet ID (PID). The default is to use
the first audio PID found at the channel-name-file.
-d, --demux=demux#
Use the given demux. Default value: 0.
-f, --frontend=frontend#
Use the given frontend. Default value: 0.
-I, --input-format=format
Format of the input file. Please notice that caps is ignored. It
can be:
channel - for dvb-apps compatible channel file;
zap - for dvb-apps compatible zap file;
dvbv5 (default) - for the dvbv5 apps format.
-l, --lnbf=LNBf_type
Type of LNBf to use 'help' lists the available ones.
-L, --search=string
Search/look for a string inside the traffic. Used only on moni‐
tor mode.
-m, --monitor
Enable monitor mode. On this mode, it will monitor de DVB traf‐
fic for all Packet IDs (PIDs) received by the device, showing
the Packet IDs (optionally filtered by a string), and presenting
some traffic statistics: number of packets per second, number of
Kbytes per second and total traffic. Those statistics are shown
per PID and the total per MPEG-TS.
-o, --output=file
Output filename. If specified, it will output the content of the
MPEG-TS into the file with the first video PID and the first
audio PID (or the one specified by audio_pid#). Use -o - for
directing the output to stdout.
-p, --pat
Add PAT and PMT MPEG-TS tables to TS recording (implies -r).
-P, --all-pids
Don't filter any pids. Instead, outputs all of them.
-r, --record
Sets up the /dev/dvb/adapteradapter#/dvr0 for MPEG-TS record.
-s, --silence
Increases silence (can be used more than once).
-S, --sat_number=satellite_number
Satellite number. Used only on satellite delivery systems. If
not specified, disable DISEqC satellite switch.
-t, --timeout=seconds
Amount of seconds to keep the tool running for zapping and for
recording. Useful if you want to record a program that you know
its duration.
-U, --freq_bpf=frequency
SCR/Unicable band-pass filter frequency to use, in kHz. Used
only on satellite delivery systems.
-v, --verbose
Be verbose. Useful to check if the MPEG-TS is happenning fine.
This option can be used multiple times to increase verbosity.
-V, --video_pid=video_pid#
video pid program to use (default 0)
-w, --lna=LNA
Enable, disable or put LNA power in auto mode. Not all frontends
support it. Valid values are:
0 - disable
1 - enable
-1 - auto
-W, --wait=time
Adds additional wait time for DISEqC command completion.
-x, --exit
Exit after tuning.
-X, --low_traffic
Also shows DVB traffic with less then 1 packet per second. Used
only in monitor mode.
-?, --help
Outputs the usage help.
--usage
Gives a short usage message.
--version
Prints program version.
EXIT STATUS
On success, it returns 0.
EXAMPLES
Recording a channel
The typical use is to tune into a channel and put it into record mode:
$ dvbv5-zap-c dvb_channel.conf 'music' -r
using demux '/dev/dvb/adapter0/demux0'
reading channels from file 'dvb_channel.conf'
service has pid type 05: 204
tuning to 573000000 Hz
audio pid 104
dvb_set_pesfilter 104
Lock (0x1f) Quality= Good Signal= 100.00% C/N= -13.80dB UCB= 70 postBER= 3.14x10^-3 PER= 0
DVR interface '/dev/dvb/adapter0/dvr0' can now be opened
The channel can be watched by playing the contents of the DVR inter‐
face, with some player that recognizes the MPEG-TS format.
For example, this audio-only channel can be playew with mplayer:
$ mplayer -cache 800 /dev/dvb/adapter0/dvr0
MPlayer SVN-r37077-4.8.2 (C) 2000-2014 MPlayer Team

Monitoring a channel
The dvbv5-zap tool can also be used to monitor a DVB channel:
$ dvbv5-zap-c dvb_channel.conf 573000000 -m
using demux '/dev/dvb/adapter0/demux0'
reading channels from file 'dvb_channel.conf'
service has pid type 05: 204
tuning to 573000000 Hz
