ChangeLog:
--------------------
2013-03-31
- adapt to vdr next version number, skipping support for vdr < 1.7.4
- fix compiling for newer frontend.h
- apply small other patches since 2012-11-11
2012-11-11
- apply patch from Michael Stilmant, who discovered two string buffers
being too small by one byte.
2012-06-05
- since some dvb drivers are buggy and dont tune DVB-S with ROLLOFF_AUTO,
therefore now explictly set ROLLOFF_35 in case of DVB-S. Thanks to R.Warsow
for report && testing.
NOTE: this is just a work-around for broken DVB-S drivers,
since DVB-S means by DVB standard *always* RO = 0.35
- print transponder data from satellite list during scan to make debug reports easier
to read

- VLC xspf output: as VLC-2.x.x no longer supports comma (VLC-1.x.x did) but only colon
as separator, update xspf output format accordingly. Thanks to Jacek Sliwerski for
report && samples.
- increase max number of supported dvb adapters, based on a patch send by Julian Scheel.
- auto scan: /dev/dvb/adapter(0..15)
- by option -a <NUM>: /dev/dvb/adapter(0..31)
- blacklist ( = look for a better device on auto scan ) Pinnacle PCTV 290e for cable:
- known to have weakness on cable because of integrated preamp
- it's driver doesnt report symbolrates correctly.
- for terrestrial scan it's still a preferred device
- no longer distribute a precompiled version of w_scan inside package.
2012-04-15
- add a missing 'break' for initial tuning data on satellite,
reported by L. Dolezel
- rework audio language descriptor to avoid segfault,
reported by L. Dolezel
- add Israel DVB-T, requested by B. Nahari
- update S13E0 transponders
- fix bug introduced by 'transponder scan logic modified' in 20120128,
which prevents -x option on US vsb/qam, reported by 'locuse'
- add experimental cmake build support. For now building with autotools
is still the standard way, but if you want to test, use
cd w_scan-<VERSION>
mkdir build && cd build
cmake ..
make
make install
2012-01-28
- modify dvb api < 5.5 logic, to find out which delsys are supported by hw
- init-data: plot only verified data
- transponder scan logic modified:
- alloc_transponder(): add newly allocated transponder only to new_transponders,
if freq not yet known.
- tune_to_transponder(): add tuned transponder only to scanned_transponders,
if freq not yet known.
- find_transponder(): replaced by find_transponder_by_freq()
- TODO: check side effects on 2nd gen delsys
2012-01-12
- add hack to allow compile against api 5.3
2012-01-11
- initial DVB-T2 support. Thanks for testing, code snippets and suggestions to Rolf Ahrenberg.
- go back to allow to compile with DVB-API >= 5.3 and remove configure check (too early)
- add video type to vdr output
- change CAid to uppercase in vdr output
- restructure Parameter print inside vdr output
- add audio type and subtitling pids if vdr version > 1.7 (even if no '1.8.0' exists yet)
2012-01-08
- fix a few compiler warnings, reported by rofa
- fix configure script to check for DVB API >= 5.5 as reported by rofa
- copy current transponder before parsing NIT in case of terrestrial
since T2 delsys descriptor doesnt report all settings belonging to hardware.
2012-01-07
- big cleanup:
- no longer tune with dvb api 3.2 drivers (pls upgrade your drivers)
- remove all occurencies of..
- BANDWIDTH_*
- FE_QPSK
- FE_QAM
- FE_OFDM
- FE_ATSC
- remove #ifdef's for features in dvb api added before 5.5;
therefore: COMPILING NOW NEEDS DVB API 5.5 OR HIGHER !
- because ofdm is no longer used by DVB-T only, Satellite frontends not
only use QPSK, DVB-C2 will use OFDM similar to DVB-T(2):
- rename ofdm_* to terr_*
- rename qam_* to cable_*
- rename qpsk_* to sat_*
- rename tuning parameters
- prepare on newer desciptors:
- add T2_delivery_system_descriptor (untested - need testers)
- add C2_delivery_system_descriptor (no linux support yet at all)
- prepare on SH_delivery_system_descriptor (no functionality yet)
- add network_change_notify_descriptor (no functionality yet)
- prepare on DVB-T2 scan:
- add bandwidths 10MHz, 1,712MHz
- add FEC_3_5, FEC_4_5 (DVB-T2)
- add QAM256 to terrestrial scan (DVB-T2)
- add transmission modes 1k,16k,32k (DVB-T2)
- add guard interval 1/128, 19/128, 19/256
- add several new items to the internal transponder tuning data for later support of
DVB-C2 and DVB-T2
- now set plp_id during tune id terrestrial scan and delivery_system = SYS_DVBT2
- try to discover supported delivery_systems per frontend using new ioctl DTV_ENUM_DELSYS
if DVB driver has api version 5.5 or higher (fallback otherwise)
- now do CRC32 checks in w_scan and prolong timeouts if CRC failures
occur (may help in some cases if bad reception)
- extend output format for 'scan' initial_tuning_data to deal with
DVB-T2/DVB-C2.
- old: # T <freq> <bw> <fec_hi> <fec_lo> <mod> <tm> <guard> <hi> [# comment]
# C <freq> <sr> <fec> <mod> [# comment]
- new: # T[2] [plp_id] [system_id] <freq> <bw> <fec_hi> <fec_lo> <mod> <tm> <guard> <hi> [# comment]
# C[2] [plp_id] [data_slice_id] [system_id] <freq> <sr> <fec> <mod> [# comment]
(NOTE: it's time to adopt 'scan' to API V5 && at least DVB-T2!)
- update documentation in ./doc to reflect file change of initial_tuning_data
2011-10-11
- add S152E0, S156E0, S166E0, update S160E0, thanks to ozvdr (Hans)
- no longer skip over the following audio formats in case of VDR output (now supported by vdr)
- 13818-7 audio w. ADTS transp syntax
- 14496-3 audio w. LATM transp syntax
- change xine output:
old: output standard audio only.
new: output AC3 audio. If not found, fall back to standard audio
- change mplayer output:
old: output '+' separated list of standard audio pids.
new: output '+' separated list of ac3 audio pids, followed by standard audio pids.
- change vlc xspf output:
- apply stray newlines patch for vlc dvb-s format,
as reported by Juergen Lock (cosmetics)
- convert to UTF-8 using glibc
- remove unneeded duplicated char recoding
2011-07-02
- add requested format 'Gstreamer Plugin dvbsrc'
- fix counting services
- cosmetics
2011-06-16
- updates to several satellites, thanks to Dotan Porat for
reporting and providing initial patches
- Nilesat 101/102 + Atlantik Bird 4A
- one transponder on Astra 19E2
- Amos 1/2/3
2011-05-02
- fix wrong ATSC 8VSB and 16VSB identifiers for xine output, thanks to M.Krufky
- now assume country = US, if frontend type = ATSC. This should work, since
most non-US countries using ATSC still use the same channel lists as US.
- now assume vdr format vdr-1.7, if VSB/QAM-B scan with vdr settings.
ATSC users of VDR anyway need to patch their sources or upgrade to
latest developer releases.
- check if choosen frontend type fits to choosen scan type
- extend -a option to allow string /dev/dvb/adapterN/frontendM
you may now use -a (0..7) or -a /dev/dvb/adapter(0..7)/frontend(0..7)
2011-04-10
- fix qam setting BR
- add option -C <charset>, output coding (default: guess users codepage).
if given, w_scan uses iconv to translate to this charset,
i.e. 'w_scan -fc -cDE -C utf-8'
if not given, w_scan tries to *guess* your charset and translates to that.
- now guess users country if -c <country> not given.
- add compiler flags: Wall, Wextra, Wno-comment, Wswitch-default, Wno-unused-parameter
- remove all remaining <TAB> whitespaces.
2011-03-29
- add Brasil ISDB-T/DVB-C, thanks to Mauro Carvalho Chehab
- changed command line option '-S':
- ordering of srates
- add 6086
- add 5217
- remove 7000, because unreasonable
- update man page accordingly
- update S23E5 TP16
2011-03-13
- update S41E9 and rename to S42E0
2011-03-06
- NOTE@maintainers: it's called 'w_scan', not 'w-scan' or 'wscan'.<br>
Please fix if mistyped in your repo.
- fix memory leak in parse-dvbscan.c:142 (dvbscan_parse_tuningdata; char * buf)
- fix memory leak in parse-dvbscan.c:489 (dvbscan_parse_rotor_positions; char * buf)
- fix double deallocating pointer in scan.c:2999 (main; int frontend_fd)
- fix memory leak in scan.c:2654 (main; char * country)
- fix memory leak in scan.c:2722 (main; char * satellite)
- fix memory leak in scan.c:3192 (main; char * initdata)

- fix octals in countries.c (backport from vdr-plugin wirbelscan-0.0.7)
- check/report hardware frequency and symbolrate limits to avoid error
messages in syslog
- fix option -L (VLC output) in case of DVB-S. Thanks to Juergen Lock.
2011-02-06
- bugfix: fix wrong comparison in check_frontend(), which lets the caller assume
that to not yet have pll lock and wait until timeout is over. This may speed up
each tuning to a new transponder a little. Thanks to Dick Streefland.
- set PILOT_AUTO on satellite transponders found by NIT. There's no flag inside NIT
to find explicitly 'ON' or 'OFF', so AUTO is the very best approach here.
Thanks to Dick Streefland.
- change <TAB> to <SPACE> in satellites.{c,h} and countries.{c.h} for better compat
with wirbelscan-0.0.6.
- add channel identifier USERLIST to channellist_t for compat with wirbelscan-0.0.6
2010-12-04

see https://bugzilla.redhat.com/show_bug.cgi?id=513871 (reported by "Stephen" and Felix Kaechele)
- changed struct tvct_channel to avoid gcc-4.4 warnings
- is_nearly_same_frequency changed to allow 2MHz on sat; 500kHz otherwise

- fixed small bug which causes endless loop in rare cases (DVB-T only)
- added man page for w_scan
2009-01-01/2009-04-25
- SYNTAX CHANGE:
w_scan now needs (!) command switch -c for defining your country. use uppercase two letters
for specifying your country, as defined by ISO 3166-1 use -c? for list:
DE = Germany

- removed folder patches (obsolet)
2008-11-06
- improved frontend detection (thanks to Hans Werner)
- added a patch for single frequency scanning, see folder patches.

2007-09-09
- added kaffeine channels.dvb format, switch -k
2007-08-07
- w_scan will no longer stop if frontend params cannot be set correctly.
This is necessary, because newest mercurial dvb drivers seem to have sometimes
difficulties with scanning complete frequency range. Additionally some cards added
to pci.ids.
2006-09-03
