vdr/player.h
Klaus Schmidinger a4112a96a6 Version 1.1.5
- Added direct access to the index data of cPalette (needed for displaying SPUs,
  thanks to Andreas Schultz).
- The status monitor function cStatus::Replaying() now gets a 'cControl *' argument instead
  of a 'cDvbPlayerControl *' in order to allow additional players to call this function.
  cPlayer and cControl have been given the functions GetIndex() and GetReplayMode() to
  allow access to the player's status.
- Added cOsd::OpenRaw() to create a raw OSD (needed for displaying SPUs).
- Changed the symantics of the Name parameter in cStatus::Recording() and
  cStatus::Replaying(). It is no longer the full directory name of the recording,
  but rather just the basic name. This has been changed to allow players that can't
  provide a name to simply use a string that describes the player type (like, e.g.,
  "DVD").
- Fixed a hangup when switching to the next file during replay.
- Fixed a possible race condition in the cDvbPlayer (thanks to Andreas Schultz
  for pointing out this one).
- Disabled channels on Transponder 12070 in 'channels.conf', which apparently no longer transmits.
