Re: dvbv5-scan needs which channel file?
Ah, thank you Olli -- much appreciated! If dvbv5-scan expects the initial scan files in the new DVBV5 format, does that mean that these still somewhat mysterious initial scan files have to be supplied, as in the link to the dtv-scan-tables? How are these initial scan files themselves generated? Surely there must be thousands of different dvb signal locations -- is linux-tv going to try to maintain these thousands of scan tables for download? What do users do when their particular location is not represented in the dtv-scan-tables.git? Finally, I'm using gnutv to record television; I imagine it still only accepts the old format? What's the new alternative?

Re: dvbv5-scan needs which channel file?
Hi David, Well, the initial scan files need to be supplied for dvbv5-scan somehow. The initial scan files that are maintained in the the git repo I posted earlier are updated by users who notice differencies. Basically I and some other users have created scripts that automatically generate the files for my country, so it's rather easy. I don't know how it works for other countries. Anyway, if you prefer to generate the data yourself you can use w_scan to generate it in DVBV3 format: w_scan -ft -c FI -x ~/initial_v3.conf Then use the dvb-format-convert tool that comes in the v4l-utils package: dvb-format-convert -I CHANNEL -O DVBV5 ~/initial_v3.conf ~/initial_data_v5.conf Then you can run dvbv5-scan with this file: dvbv5-scan ~/initial_data_v5.conf Alternatively you can skip the whole conversion phase and run dvbv5-scan with the DVBV3 initial tuning data: dvbv5-scan -I CHANNEL ~/initial_v3.conf Cheers, -olli On 30 December 2014 at 10:23, David Liontooth lionte...@cogweb.net wrote: Ah, thank you Olli -- much appreciated!

Re: dvbv5-scan needs which channel file?
Hi David, Em Tue, 30 Dec 2014 07:49:05 -0800 David Liontooth lionte...@cogweb.net escreveu: OK, perfect; thank you. This should be documented in dvbv5-scan. And we should have a man page for it. This is documented, and there is a man page for it: dvbv5-scan(1)User Commands dvbv5-scan(1) NAME dvbv5-scan - DVBv5 tool for frequency scanning SYNOPSIS dvbv5-scan [OPTION]... initial-file DESCRIPTION dvbv5-scan is a command line frequency scanning 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-scan uses by default the 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. A single physical channel (also called as transponder) may have several virtual channels inside it, encapsulated via a MPEG Transport stream. Those virtual channels are called as 'service' at the MPEG-TS terminol‐ ogy, and may have one or more audio, video and other types of elements inside it. The dvbv5-scan goal is to scan for a list of physical chan‐ nels/transponders and identify there the MPEG-TS services available. The dvbv5-scan tool is smart enough to retrieve the information at the MPEG-TS Network Information Table (NIT) about other channels available on the stream. OPTIONS The following options are valid: -3, --dvbv3 Force dvbv5-scan to use DVBv3 only. -a, --adapter=adapter# Use the given adapter. Default value: 0. -d, --demux=demux# Use the given demux. Default value: 0. -f, --frontend=frontend# Use the given frontend. Default value: 0. -F, --file-freqs-only Don't use the other frequencies discovered during scan. By default, dvbv5-scan will find new transponder/physical channels and add them at the internal frequency table it uses for scan. This option disables such feature. -G, --get_frontend Use data from get_frontend on the output file. By default, dvbv5-scan will repeat the same network parameters as found at the scan file. This should work fine if the output file will be used by the same frontend. However, if you intend to use the generated file on another frontend, or wants a faster tuner, this option can be used to store the actual detected parameters, instead of the ones that came from the source channel file. -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. -N, --nit Use data from NIT table on the output file. By default, dvbv5-scan will repeat the same network parameters as found at the scan file. This should work fine if the output file will be used by the same frontend. However, if you intend to use the generated file on another frontend, or wants a faster tuner, this option can be used to store the parameters that are announced by the broadcaster via the MPEG-TS Network Information Table (NIT), instead of the ones that came from the source chan‐ nel file. -o, --output=file output filename (default: dvb_channel.conf) -O, --output-format=format Output format: channel - for dvb-apps compatible channel file; zap - for dvb-apps compatible zap file; vdr - for vdr compatible zap file; dvbv5 (default) - for the dvbv5 apps format. -p, --parse-other-nit Parse the other NIT/SDT tables that could be found mainly on some DVB-C carriers. -S, --sat_number=satellite_number Satellite number. Used only on satellite delivery systems. If not specified, disable DISEqC satellite switch. -T, --timeout-multiply=factor Multiply the scan lock wait time and MPEG-TS table parsing by this factor. -U, --freq_bpf=frequency SCR/Unicable band-pass filter frequency to use, in kHz. Used only on satellite delivery systems. -v, --verbose

Re: dvbv5-scan needs which channel file?
Hello David, Coincidentally I was just yesterday working with dvbv5-scan and the initial scan files. dvbv5-scan expects the initial scan files in the new DVBV5 format. w_scan is not producing results in this format. The scan tables at http://git.linuxtv.org/cgit.cgi/dtv-scan-tables.git/ are in the new format. Some of them are a bit outdated though (send in a patch if you can update it for your area). The v4l-utils package also includes tools to convert between the old and the new format.
