vdr/libsi/headers.h
Klaus Schmidinger 293ed4027e Version 1.3.47 
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Fixed a crash when setting the time transponder in the Setup menu, caused by the
  new 'noneString' in cMenuEditChanItem (reported by Thomas Günther).
- Added NULL checks to some strdup() calls in menuitems.c (suggested by Darren
  Salt).
- Removed the unnecessary 'value' member from cMenuEditItem.
- Fixed the initial setting of the time transponder setup parameter (reported
  by Thomas Günther).
- Fixed unnecessary Set() calls in cMenuEditIntItem::ProcessKey().
- Allowing a tolerance for symbol rate values that are off by one (thanks to
  Richard Lithvall).
- Added VBITeletextDescriptorTag, TeletextDescriptorTag, LocalTimeOffsetDescriptorTag
  and PremiereContentTransmissionDescriptor to 'libsi' (thanks to Marco Schlüßler).
- Using geteuid() to check whether VDR is running as user 'root' (suggested by
  Tobias Grimm).
- Added a missing "Key$" in skincurses.c (reported by Darren Salt).
- Reintroduced the log message "deleting plugin: ..." when shutting down VDR (upon
  request by Ville Skyttä, as in the initial patch from Christoph Haubrich).
- Fixed the vdr.1 man page (a single DVB card can record and do live tv).
- The preferred audio language is now automatically selected when starting replay.
- Updated the Danish OSD texts (thanks to Mogens Elneff).
- The new function cPlugin::Active() can be used by a plugin to indicate that it
  is still busy and the system should not shut down or restart (based on a patch
  from Sascha Volkenandt). See PLUGINS.html for details.
- Fixed setting the 'Delta' parameter when calling the shutdown script with
  no active timer (reported by Helge Lenz).
- In order to make sure that plugins are compiled with the same DVB driver header
  files as VDR itself, the definition of DVBDIR has been removed from the VDR
  Makefile. If you are using a driver version that has its header files at a location
  other than /usr/include/linux/dvb, you can define DVBDIR in the Make.config
  file (see also INSTALL). Note that if you already have a Make.config file of your
  own, you should add the lines

  ifdef DVBDIR
  INCLUDES += -I$(DVBDIR)/include
  endif

  to its end, as in the new Make.config.template.
  Any reference to DVBDIR should be removed from all plugins' Makefiles, like this:

  Thanks to Marco Schlüßler for pointing out this problem.
- Implemented kNext and kPrev keys (based on a patch from Peter Juszack).
  See MANUAL for details.
- Implemented kChanPrev (from a patch from Darren Salt).
- The "Update channels" parameter in the "Setup/DVB" menu has been extended to
  allow updating only the PIDs (see MANUAL for details). When updating to this
  version of VDR, please verify that the setting is as you want it to be, because
  the values have been shifted.
- The new APIVERSION (see config.h) now allows existing compiled plugins to be
  used with newer versions of VDR, as long as there have been no changes to the
  VDR header files since the last APIVERSION. Existing plugins' Makefiles should
  have all references to VDRVERSION changed to APIVERSION, like this:

- If a timer is newly created from within the "Schedule" menu, and its event is
  already running or has its start time within the next two minutes, it now goes
  directly into the "Edit timer" menu in order to allow the user to make further
  changes to timer parameters before the actual recording starts (inspired by
  Christian Wieninger's "epgsearch" plugin).
- Added format check to syslog_with_tid().
- Updated the INSTALL file's section about non-VDR files in the video directory
  (since version 1.3.38 disk access is done in a separate thread, so the watchdog
  timer won't hit).
- Changed the behaviour of the "Use small font" setup option to *always* use the small
  font if set to '2' - even if it would have been a fixed font (suggested by Ronny
  Kornexl).
- No longer using characters 0x01 and 0x02 for mapping single quote and slash in
  recording names (thanks to Patrick Fischer for reporting that this was a problem
  with XML). The single quote is not mapped at all, and the slash is interchanged
  with the tilde. Existing recordings will be handled like before, so there is
  no need to actually rename them.
- The cRemote::CallPlugin() function now has a boolean return value that tells
  the caller whether initiating the plugin call was successful (suggested by
  Reinhard Nissl). If it returns false, another plugin call is currently pending
  and the caller should try again later. This also means that the SVDRP command
  PLUG can now return an error code is the call fails.
- The new function cPlugin::MainThreadHook() can be used by plugins to perform
  actions in the context of the main program thread. Use this function with great
  care and only of you absolutely have to! See also PLUGINS.html.
