Re: [ANNOUNCE] scan-s2 is available, please test

["Alex Betis" <alex.betis@xxxxxxxxx>]

Some more updates for scan-s2:
- Fixed skip count specified by "-k" option (skipped one message less than specified).
- Removed dumping (null) provider name.
- Fixed DVB-T tuning. Thanks to Hans Werner.
- Fixed some network ID output problems. Thanks to Oleg Roitburd.
- Added options to specify "S1" and "S2" entries in frequency file that will use DVB-S and DVB-S2 scan modes respectively.
- Added "-D" option to disable scanning of some modes. "-D S1" will disable DVB-S scan, "-D S2" will disable DVB-S2 scan.
- Added 3/5 and 9/10 FEC options. Thanks to Michael Verbraak.

In my TODO list so far:
- Revise and add diseqc motor support patch from Hans Werner.
- Revise and add few more patches sent by different people.
- Revise NIT message parsing to figure out why it doesn't add transponders with correct delivery system.
- Add UTF-8 channels encoding support.

Please test the latest version of scan-s2 from:
http://mercurial.intuxication.org/hg/scan-s2/

Let me know if something doesn't work as it should.

Thanks.
Alex.

Hi all,

Some updates for scan-s2:
- Frequency files parameters that can specify AUTO are now optional, not required to appear in the file. See README.
- Added ROLLOFF and modulation specification for DVB-S format. See README.
- Fixed usage of -n (network search) switch. NIT messages will not add new transponders by default now, so add -n if you really want it.
- NIT messages will not update existing transponders any more. After seeing several bad NIT messages that caused to miss channels I think that will be better that way.
- Added dumping of modulation and rolloff to VDR format file. The program queries the driver after successful tuning to get real parameters of the channel. Currently the driver do not return real values except for FEC, so if you specify AUTO values the output file will not have the real rolloff and modulation values. Igor said he will look at it.
- Added CAID dump to VDR file format, see "-x -2" switch.
- "-x XXX" switch opeation is fixed. Don't know who might want to use it after real CAID dump (option -2) and dump zeroes to CAID (option -1) is available.


Currently my TODO list include UTF channel names encoding. If you think of something else, please let me know and I'll try to add.

Please test the latest version of scan-s2 from:

Enjoy,
Alex.

Thanks. I'll use it in the dump.

i have seen, that FEC will be set if FEC is in initial file.
If transponder was found via NIT it will be not set

Yeah, it was my change since I saw NIT specifying incorrect FEC for a channel that was in my frequency list already!
I'll probably change it so NIT will be considered as the correct info unless frequency list include non-AUTO value.
This way it will be possible to overwrite values or rely on network announcements if you want full automatic behavior.
