vdr/remux.h
Klaus Schmidinger 49b561fcad Version 1.3.45
- Fixed updating the "Info" button in the "Timers" menu.
- Reduced the number of events to actually check when setting events to timers.
- cMenuEditIntItem now checks the given value and forces it to be between the
  given min and max limits.
- The status changes of EPG events are now logged for all channels that have timers.
- Removed the log message "deleting plugin: ..." when shutting down VDR (thanks to
  Christoph Haubrich for reporting that this is irritating when calling "vdr --help").
- Fixed cReadLine::Read() for lines that end with the infamous "\r\n" (thanks to
  Rolf Ahrenberg).
- Fixed cDvbDevice::SetAudioBypass() in case setTransferModeForDolbyDigital is false
  (thanks to Werner Fink).
- Updated 'sources.conf' (thanks to Oleg Roitburd).
- Fixed the shutdown timeout (thanks to Alexander Wenzel).
- Only calling RemoveEmptyVideoDirectories() once in case a recording has been
  deleted (reported by Hardy Flor).
- Fixed deleting recordings that have been removed externally when running out of
  disk space (reported by Jan Lenz).
- Fixed handling repeating VPS timers (they stopped recording too early).
- Timer log messages now show "VPS" if this is a VPS timer.
- Fixed getting the present EPG event in case none is currently 'running' (it
  then returns the one that just ended).
- Fixed calling a plugin's main menu function while a message is being displayed
  (reported by Helmut Auer).
- Updated the Russian OSD texts (thanks to Oleg Roitburd).
- Made cMenuRecordings::GetRecording() 'protected' (suggested by Marius Heidenstecker).
- Speeded up cRemux::ScanVideoPacket() (thanks to Reinhard Nissl).
- Enhanced logging EPG event data.
- Fixed format string handling (thanks to Darren Salt).
- The new function cDevice::ForceTransferMode() can be used to force the primary
  device into transfer mode (thanks to Reinhard Nissl).
- The 'version' of EPG events is now ignored when reading EPG data from 'epg.data'
  or via SVDRP/PUTE to avoid problems with double EPG events.
- The 'running status' of EPG events is now only set to SI::RunningStatusNotRunning
  for events before the present event.
- Fixed some #include sequences.
- Single shot VPS timers are now only considered 'expired' if their associated
  EPG event has been explicitly set to SI::RunningStatusNotRunning.
- The check for timers to be deleted is now done only every 30 seconds.
